Lincoln Elementary School Project Overview
The original 49,706 square foot two story building was constructed in 1948-49. A 1,060 square foot administrative addition was added in 2014. The site is approximately 4 acres in size and urban-residential in nature.
The renovated Lincoln Elementary school project is proposed as a 450 student, 56,000 square foot K-5 school located on the existing Lincoln Elementary site. The renovated school would contain general classrooms, resource rooms, library, kitchen, gymnasium, commons, music room, administrative, counseling, and educational support spaces.
Prior to the renovation work beginning at Lincoln Elementary the students and staff will relocate to the New Elementary completed at North Cora Street. Students and staff will be temporarily housed at the new facility while the existing Lincoln Elementary structure will be abated and renovated. After completion of building and site renovations at Lincoln Elementary, students and staff move back to the renovated building.
Lincoln Elementary Value Analysis
Prior to the planning and visioning process documented in this educational specification the District charged the project/construction manager, OAC Services, and Integrus Architecture with evaluating the original 2018 bond plan and validating the budgets and projects proposed.
The District project/construction manager, architect and structural engineer have reviewed in detail the original building construction documents and several engineering reports dated 2003-2015 to assess potential design and construction challenges. Of particular note were the reports recommending several projects to improve-upgrade the seismic condition of the structure. The documentation contains descriptions of several projects that have implemented these recommended projects, dated 2003-2015.
As part of this process, the design team reviewed the building condition assessment report for Lincoln Elementary School and determined that the original 1948 construction has significant remaining residual value to the community and District. The existing structure and systems would require significant alterations and updates, but it is proposed that this structure remain.
Renovation Explanation
As part of a comprehensive planning process for November, 2018 Capital Improvement bond election, Ellensburg School District has commissioned a study of Lincoln Elementary School to determine the feasibility of fully modernizing and adding necessary new construction to Lincoln in order to create a fully updated elementary school for 21st Century education, which will meet the needs of the Ellensburg community for many years to come. Lincoln Elementary was originally constructed in 1948-49 and is 49,607 square feet in size. It is a two-story building with low slope roofs. The classrooms are arranged along a central corridor with the administration, gymnasium, and music room (originally a locker room) forming a north wing. The cafeteria and kitchen are located on the east side of the building as a one-story wing as well. The site is approximately four acres. As such, on-site parking and playground areas are limited. Compounding this problem are three portable classroom buildings that sit at the south side of the site. Two covered play areas are located on the east side of the building one near the kitchen, and one near the gym. Because the kitchen is situated where it is, a delivery drive bisects the existing play area, creating a substantially dangerous risk of accidents. The building is fairly close to the street on both the west and north sides.
The new design is based on the list of program spaces with an ideal capacity of 450 students based on the number of classrooms, specialty spaces, and sizes of core spaces (gym, administration, library, etc.). Combining the existing renovated spaces with new construction, the design includes a total of approximately 56,000 square feet. The plan organization is heavily influenced by the desire to construct a new full-sized gymnasium. The existing gym is undersized, even for an elementary school and would be very difficult to enlarge in place. Therefore, the design indicates a new full-size gym to be constructed. The cafeteria and kitchen would then be relocated to the gym’s previous location, taking advantage of this space’s volume and better location on site; deliveries would no longer need to cut across the playground.
The library and music rooms would be moved to the previous location of the cafeteria and kitchen. This floor level would be raised to a level that would allow access via an interior ramp. The administration area would remain in its current location. In general, the classrooms would still be arranged along the central corridor, but reconfigured to maximize their size. Small group break-out spaces have been accommodated at several locations along the main corridor.
Additional off-street parking would be constructed west, creating a new visitor parking and parent drop off driveway. Bus traffic would extend along Capitol Avenue on the north side of the school. Existing outdoor hardscape play areas will remain intact, as will the open green space areas.
The building will be required to meet the building envelope performance requirements of the current Washington State Energy Code. Abatement will be completed for the entire facility. Among other things, this will require all new thermal insulation (walls, floors, perhaps roof) as well as replacement of any windows, which were not replaced as part of the recent upgrades. In general, there are several seismic upgrades, mostly related to the unreinforced masonry walls that are required to bring the building up to a safe level as well. Finally, a completely new Mechanical, Electrical, and Plumbing system will be installed replacing the existing infrastructure, to include fire suppression.

Executive Summary & Overview
Executive Summary
In creating this Educational Specification, Integrus Architecture was asked to continue the transparent and inclusive process that the District used to plan and pass the November 2018 bond. The bond included a New Elementary School project and two existing elementary schools. These projects will house over three fourths of the District’s elementary students.
- Three two-hour work sessions focused on Lincoln Elementary
- Previous work completed in early 2019
Explored are the above processes used to develop the goals, vision, and guiding principles for the program and design of the elementary schools. Site specific elements and program spaces for Lincoln Elementary are included. The design team and administration will use this specification to validate each aspect of the project to insure they meet the high standards of the Ellensburg School District and the Ellensburg Community.
Process Overview
Continuing the conversation around building organization, the design committee worked in small groups to identify potential solutions that integrated the learning neighborhoods with the heart of the school. The groups were given learning neighborhoods with options for three, four, five, or six classroom groupings. Four potential solutions were identified. The committee then proceeded to take these solutions and apply them to the Lincoln Elementary School site. The groups were guided through identifying the key features of the site such as student drop-off, bus loading, building front door, parking and play activities. This process provided the design committee with the opportunity to identify priorities for connections within the building as well as throughout the sites.

Visioning
Visioning
The design of a new school cannot begin without first establishing a common vision and direction confirmed with all the stakeholders. To achieve this, Education Specification meetings were organized around a series of visioning presentations, discussions, and exercises.
The process started with an understanding of Ellensburg School District's Mission and Values:
“All students will graduate prepared for life’s opportunities. We believe that learning opens doors and gives students the chance to open doors throughout their lives. We strive to cultivate habits of excellence that stay with our students long after they leave our district.”
This vision and mission were reviewed along with the current District educational approach, curriculum, and future curriculum goals. The discussion started with, “How could these new facilities support and enhance teaching and learning in the District?” To help the design team and committee answer this, the first meeting revolved around two different exercises “Blink” and “Hopes & Fears.” “Blink” gives an often unexpected snapshot to show a common ground perspective as it relates to various types of spaces in and outside a building. For the exercise “Hopes & Fears,” the design committee first gave comments on post-it notes on a variety of topics, then later chose images that resonated with their hopes, dreams and/or fears for the new schools and captured the committee’s thoughts and priorities on boards.
Other exercises included activities such as “A Day in the Life” which charted the path of building users throughout the day through the lens of Howard Gardner’s Eight intelligences. The Environmental Workshop captured ideas about responsible design solutions for Ellensburg’s elementary schools. The workshop covered four major areas of sustainable design including site and water usage, materials selection, building systems, and renewable energy.
The renovated Lincoln will:
“... be welcoming to all as it honors the past and embraces the future.”
The renovated Lincoln will:
“... honor the historical character and legacy of our building while providing a space that fosters creativity and builds community.”
The renovated Lincoln will:
“... maintain its historical character and sense of community while incorporating modern-day and futuristic accommodations to serve generations to come within the Ellensburg community.”
The renovated Lincoln will:
“... remain a historic building that can be creatively adapted , both physically & educationally, for the needs of the current students and those to come in the next half century. It will be full of daylight and the walls will be covered with student work.”
Guiding Principles

Group Exercises
Six topics common in school design were posted as initial talking points of discussion:
- Community Use
- Outdoor Learning & Play
- Teaching & Teaming
- Safety & Security
- Maintenance & Durability
- Space Needs
The Education Specification Planning Committee and the design team discussed hopes and fears surrounding these topics. As they talked, committee members wrote down their feelings on sticky notes and posted them on each general topic.
The design team then brought out a variety of images both of the existing Mt. Stuart and Lincoln Elementary schools as well as images of physical space and activities that would inspire further discussion on each of the topic. The design committee was asked to add these images to the existing hopes and fears boards and further their comments with images that were relevant to their thoughts on each topic. At the end of the exercise, a comprehensive documentation of the committee’s hopes and fears remained.

These sessions provided insight into how the current Lincoln Elementary building functions for the staff and community as well as the opportunities to improve and make new functions work. The group analyzed what elements of the existing Lincoln were important to keep. They shared how students function in the context of a school day. They reviewed alternate ways of organizing learning neighborhoods and carried those thoughts into adjacency exercises with the new program.
Keep, Add, Change
This exercise was intended to establish a baseline of the important existing characteristics of Lincoln as well as the existing challenges in the building and on site. These three categories provided a positive way to look at the needs of the school in relationship to what is currently available, what is missing, and what must evolve to help students continue to find success. These items listed here frequently reappeared in other discussions and exercises and began to illustrate the committee’s priorities.

Project Adjacencies
Relationships
After the development of the goals and vision for the project with the design committee, the group worked together to examine the relationships within learning communities and to identify the essential community elements of the school. A number of example organizations were reviewed from the virtual tours and the physical tours the committee participated in. These high-level concepts informed the process of the committee to identify organizational diagrams that fit both the current and future teaching and learning needs of the schools.
For Lincoln Elementary, the design committee reviewed the examples of neighborhoods and learning communities shown here and participated in several exercises to identify the important relationships within the existing building. These examples and exercises are included here.
Day in the Life of Lincoln
The Lincoln “Day in the Life” exercise is intended to identify the transitions and sequences for student activities during the school day. It illustrates which spaces students use the most and helps the design team find opportunities for collaboration, socialization, exploration, formal and informal gathering, creativity, and community use throughout the student’s day. The exercise also provides opportunities for staff and educators to discover unique challenges some students face. The groups chose a fictional representative student to base their day in the life around. Discussions revolved around key points in the day including arrival, meals, support, and play.
The committee identified a few key observations in this process. Those listed below are considerations the final design for the renovated Lincoln should address.
- Students participate in approximately 8-15 transitions throughout the school day, depending on their individual support needs
- Students with the most support needs often have to travel the furthest based on staff locations within the existing building and portables
- The majority of transitions take 30-60 seconds for students. Most accomplish this well, but some can get distracted en route. Limiting time and distance of unaccompanied transitions is preferable.
Learning Space Neighborhoods
During the visioning sessions, significant discussions surrounding the concept of Learning Neighborhoods were had. The concept is characterized by a group of classrooms or learning spaces adjacent/surrounding a shared learning area.
This philosophy allows the classroom to flow into the shared area during activities or presentations providing a level of flexibility and variety. It allows classrooms to utilize a larger learning area outside of the formal classroom as lessons dictate. Independent study, group work, team teaching, and project based learning are a few of the many activities possible in the shared learning space. The shared learning space also provides space for reading and social interactions outside of a formal classroom setting. The shared learning and shared conference space provide a variety of pullout spaces for students with specialists such as Title I or speech, language, etc.
Locating the shared area off the main hall separates traffic from these learning areas, improving acoustic separation for both the shared space and the classrooms. Additionally, creating these neighborhoods allows for daylighting and views to each group of classrooms, enhancing the overall connectivity between the interior to the exterior.
These concepts and goals were reviewed for Lincoln and conform to the needs of students and staff desires. The existing building presents some challenges for these concepts, but opportunities were explored in the adjacency exercise and should be continued as part of the design process.
Adjacencies
The Lincoln Design Committee worked in groups of three to five individuals to discuss the needs identified in the previous exercises and lay out options for the relationships between classrooms, support spaces, specialists, and community spaces. These adjacencies were informed by the Day in the Life exercise and groups were asked to focus on a particular grade level for classroom layouts. The committee worked with scale program element coins to represent their ideas over the existing building floor plans.
For the exercise, existing building elements were removed other than exterior walls and circulation. Groups were encouraged to think outside the present building condition in order to identify desired relationships between program elements. Some results here may be challenging to realize in the final building. However, the relationships identified can inform the design process and provide a reference point when evaluating options.
Key ideas explored included the relationship of classrooms to shared learning areas and to support spaces. Resource and Title spaces were in all examples located for easy access and transition by students from their primary classroom. Restrooms were not completely illustrated in each diagram, but were a common discussion. The current separated locations of restrooms with no way to observe hand washing are a challenge. The desires expressed by the committee included either a central location on the classroom corridor or restrooms at either end. This would reduce challenges faced by in-class restroom breaks as well as supervision of divided locations.
Community spaces were examined in the context of access and program needs. Different groups were assigned to review alternate gym locations. The discussion around gymnasium needs included an independent and acoustically isolated music classroom as well as the need for a performance stage for large group assemblies. Options were discussed for adjacent cafeteria and gym space that could be opened to each other. Some of these opportunities are dependent on the final location of the gym addition. The gym location discussions were mostly dependent on site needs are reflected in site diagrams.
Building Diagrams & Site Relationships
Building Diagrams & Site Relationships
The existing building and site were examined in several group exercises. Continuing the conversation around building organization, the design team organized the ideas presented in the building adjacency and site planning workshops to create two site diagrams and three building diagram concepts. These illustrate the concepts discussed by the design committee and will serve as a starting point for the District and design/build team to evaluate during the design process. Each diagram has some merits and some challenges, which will need to be explored further.
Building Diagram A
Diagram A represents the initial concept laid out in the 2018 bond. Classrooms are located predominately in their existing locations. Some classroom space is reclaimed at both floors to reach the desired count. A new stair is created with the gym addition at the south to provide some of that captured space on the second floor over the existing stair. The elevator is located at the south end and serves the three existing levels. The gymnasium is located on the lowest level matching the current cafeteria floor elevation. Commons, Gymnasium, and Library all have direct access to the playground areas. A new public entry would be created at the gymnasium for after-hours activities.
Building Diagram B
Diagram B represents an alternate location for the gymnasium addition at the north end of the site. This co-locates the major community spaces for after hours use and direct access from the main entry. Commons, Gymnasium, and Library all have direct access to the playground areas.
Some classroom space is reclaimed at both floors to reach the desired count. The second floor centralizes restrooms and reclaims space at the north end to capture an additional classroom. A new elevator connects all existing levels.
Building Diagram C
Diagram C represents an alternate approach for the gymnasium. This would be a full-size high school court split with an operable wall that serves both cafeteria and PE during the day, but can be opened up for after hours use and assemblies. This option was discussed in either the north or south location.
This option also frees up the existing gymnasium to serve as a library or other teaching space. Other ideas from the design committee included kindergarten space, music space, or adding a level for additional second floor space. This option would not require capturing additional space on the second floor to meet the classroom count goal.
- Bus Drop Off Area — Designated on the East side of the building
- Car Drop Off Area — Drop off driveway added on-site at main entrance
- Delivery Access — Direct connection from street to kitchen
- Parking Lot — Increase existing lot & improve layout
- Playgrounds — Replace with new play equipment & consider artificial turf
- Track — Add new designate Daily Mile path
- Provide opportunity for small container garden for science projects
- Soften hard surface play edges to reduce noise at classroom windows
- “Leafer” — Preserve tree for respite
- Bus Drop Off Area — Designated on the North side of the building
- Car Drop Off Area — Designated on the East and West sides of the building
- One Way Street — Propose one way traffic on Sampson for student safety
- Delivery Access — Direct access to kitchen from street & service lot
- Parking Lot — Increase existing layout: xx sq. ft. xx stalls
- Service Lot — Add new parking lot: xx sq. ft. xx stalls
- Outdoor Learning — Add fenced & designated outdoor space on lawn at West side of building
- Playgrounds — Replace with new play equipment & consider artificial turf
- Shade structure for respite & quiet play
- Track — Provide designated pathway for PE activities & Daily Mile. 1/5 mile loop as shown.
- Hill — Preserve hill for play & winter activities
- “Leafer” — Preserve tree for respite
Programs
The spaces are based on the District’s previous Education Specification work for general education spaces. They are in alignment with specialist needs and available existing building square footage. This summary was used by the committee in the previous exercises regarding building and site arrangements. It will guide the design team going forward and serve as the primary reference check on program size and space. The final building design will have a target of 5% variance from the sizes shown. Some flexibility may be required as the program is adapted to the existing building.
Program Priorities
During the final design committee meeting, the group was asked to vote with E-Bucks to identify program priorities. These priorities were intended to serve as a reference point for the design team as the program is adapted and fit into the existing building. The baseline assumption for the exercise was that half of the bucks were already spent on infrastructure such as HVAC, lighting, and elevator access. Each individual was then given ten bucks to spend on six program priorities. Discussion followed to understand the priorities.
The top three priorities included Support Spaces, Classrooms, and Playground/Site needs.
- Must meet the needs of diverse learners
- Must be available all day
- Shared space should not be in hallways
- Collaborative & support space should be available on both floors
- Should be equal in size
- Provide the same amount of storage in each
- Maintain the “Magic Closets”
- Provide storage for student items, i.e. cubbies or other built-in options
- Provide for a variety of play options
- Support discovery-based play
- Provide shade elements
- Provide quiet/contemplative space
- Mitigate seasonal challenges such as mud & ice on existing grass areas
- Support P.E., Daily Mile, & other fitness activities
Proposed Plan
The Lincoln Elementary Modernization and Addition school project is proposed as a 450-500 student, 56,000-58,000 sq. ft. Kindergarten-5th school located on the existing Lincoln Elementary site. The modernized school and additions would contain general classrooms, resource rooms, library, kitchen, gymnasium, commons, music room, administrative, counseling, and educational support spaces.
The Lincoln Elementary Modernization and Addition project will include type 1 and type 2 renovations to the existing building structure. The original two-story Lincoln Elementary was constructed in 1948-49 and is proposed to be modernized along with the 1,060 sq. ft. administrative addition that was added in 2014. Additions of approximately 7-10,000 sq. ft. consisting of new gymnasium and associated support spaces are proposed. The addition will also include a new elevator. New playground equipment and updates to the play areas will be provided as well. Existing portable classroom structures will be removed from the site with expanded parking approximately in the same area consisting of 15-20 additional parking spaces. It is our understanding that an 85 foot stream buffer extends onto the site in the southwest corner of the site south of the existing portables, but no new construction is anticipated in this area. The site is approximately four acres in size and urban-residential in nature.

Exploring the Site
The original 49,706 square foot two-story building was constructed in 1948-49. A 1,060 square foot administrative addition was added in 2014. The site is approximately 4 acres in size and urban-residential in nature.
The renovated Lincoln Elementary school project is proposed as a 450 student, 56,000 square foot K-5 school located on the existing Lincoln Elementary site. The renovated school would contain general classrooms, resource rooms, library, kitchen, gymnasium, commons, music room, administrative, counseling, and educational support spaces.
Prior to the renovation work beginning at Lincoln Elementary, the students and staff will relocate to the New Elementary completed at North Cora Street, north of Mt. Stuart Elementary School. Students and staff will be temporarily housed at the new facility while the existing Lincoln Elementary structure will be abated and renovated. After completion of building and site renovations at Lincoln Elementary, students and staff will move back to the renovated building.
Lincoln Elementary School is located near downtown Ellensburg, WA within a “Public Reserve” zone surrounded by residential development (residential medium density, R-M). The school is bordered by Capitol Avenue to the north, Walnut Street to the east, Sampson Street to the west, and residences to the south. Morgan Middle School is located just to the northwest across Capitol Avenue. The school’s main entry is located via a recent administration addition at the northwest corner off Sampson Street. The existing two-story school building is oriented north-south facing Sampson Street with a one-story gym-music volume running east-west long the north side of the site facing Capitol Avenue. Three portable classroom structures are located south of the existing main school building. An existing parking lot with twenty spaces is located to the south off Sampson Street. Play fields are located along the east side of the site. The site is nearly 4 acres. A creek is located to the southwest across Sampson Street south of Washington Avenue. There is an 85-foot stream buffer associated with the creek that extends on to the southwest corner of the school site.
Automobile drop-off and pick-up occurs curb side along Sampson Street; bus drop-off occurs curb side along Walnut Street. In addition to the school’s parking lot, street parking around the school is available along Capitol Avenue and adjacent neighborhood streets. The existing kitchen and cafeteria are located in the middle of the site to the east of the two-story classroom wing. The interior location of the kitchen requires kitchen deliveries to cross the middle of the playground, which is a safety concern.
Ellensburg is centrally located in Washington State east of the Cascade Range and is at an elevation of 1,542 feet above sea level. Located in the Cascade rain shadow, Ellensburg experiences a typical intermountain cool, semi-arid climate with just less than 10 inches of precipitation per year. Winter temperatures average between 19-40 degrees, while summer temperatures average between 50-84 degrees. Prevailing winds for the site, both in duration and magnitude, are from the northwest. The location of the existing school building on the northwest corner of the site helps buffer the wind and protect the play areas to the east and south. This orientation also supports the development of a courtyard south of the existing gym. The existing classrooms were designed to receive ample daylight; tall ceilings with extensive translucent panels above clear vision windows allow high levels of natural light deep into the classrooms. The north-south orientation of the existing classroom wing presents some glare and heat gain challenges for the east and west facing classrooms, however, the issue of glare is mitigated with the use of only a low narrow band of clear glass, and the majority of the light being brought in is through translucent means, which is much more diffuse.
Shaping the Building
Listen. Process. Draw. Repeat.
The Lincoln Elementary Modernization and Addition school project is proposed as a 450-500 student, 56,000-58,000 square foot K-5 school located on the existing Lincoln Elementary site. The modernized school and additions will contain general classrooms, resource rooms, library, kitchen, gymnasium, commons, music room, administrative, counseling, and educational support spaces.
The Lincoln Elementary Modernization and Addition project will include Type 1 and Type 2 renovations to the existing building structure. The project scope will keep Type 2 renovations below the IEBC threshold of 50%, so substantial alternation criteria is not triggered. The original two-story Lincoln Elementary was constructed in 1948-49 and is proposed to be modernized along with the 1,060 square foot administrative addition added in 2014. Additions of approximately 7,000 square feet consisting of new gymnasium, music classroom, and elevator are proposed. New playground equipment and updates to the play areas will be provided as well.
Existing portable classroom structures will be removed from the site with expanded parking approximately in the same area consisting of 15-20 additional parking spaces. It is our understanding that an 85 foot stream buffer extends onto the site in the southwest corner of the site south of the existing portables, but no new construction is anticipated in this area. The site is approximately 4 acres in size and urban-residential in nature. There were a variety of programmatic and site constraints that helped guide the site diagram and spatial arrangements for the renovated Lincoln Elementary.
Many of the committee’s and students’ favorite elements from the Educational Specifications are carried into the schematic design phase of the modernized Lincoln Elementary School. Natural daylight, flexible teaching areas, a comfortable building scale for kids, views to outside, landscaping, greenery, and courtyards where kids have a protected area to explore, learn, and engage in an outdoor learning environment are fundamental to the design of the updated facility.
- Classrooms — The school will house a K-5 configuration with a suite of specialist instructional areas. Every classroom has views to the exterior and an abundance of natural daylight. The existing historic classroom character will be maintained as much as possible while being brought up to current educational standards. Existing casework, built-ins, and the “magic door” closets will be reused and refreshed wherever practical.
- Library — The new school library will be relocated to the first-floor level to increase accessibly to the school community and availability for after hours use. The new location, in the original kindergarten room, allows the opportunity to reopen the large, historic window projection with new windows to create a daylit space. The library will be developed with student centered amenities that inspire a love of reading and learning.
- Guiding Principals:
- Image/Identity — Respect the existing historic Lincoln Elementary School interior and exterior and develop additions that are harmonious and complimentary to the existing building, while also being expressive of their own time. New additions will endeavor to touch the existing building as lightly as possible.
- Teaching/Learning — Provide supportive and inclusive spaces that encourage student/staff interaction and inspire student learning, exploration, and collaboration.
- Outdoor Learning/Play — Provide inviting outdoor gathering, teaching and play areas that promote learning, exploration and connection to the environment.
- Safety/Security — Create a warm, welcoming facility that nurtures community values and promotes a feeling of inclusion, comfort and safety.
- Maintenance/Durability — Develop a facility that is easily accessible, easy to use and easy to maintain.
Through an open exchange of ideas and our research-backed design approach, we are continually building on previous work while fostering an attitude that encourages innovative break-through thinking. To maintain this attitude, we are critical of everything we do and restless in our pursuit of ever-better results.
Exploration Sketches
Diagram A — Gym Addition to the South
Diagram A represents the initial concept laid out in the 2018 bond. Classrooms are located predominately in their existing locations. Some classroom space is reclaimed at both floors to reach the desired count. A new stair is created with the gym addition at the south to provide some of that captured space on the second floor over the existing stair. The elevator is located at the south end and serves the three existing levels. The gymnasium is located on the lowest level matching the current cafeteria floor elevation.
Commons and Gymnasium both have direct access to the playground areas. A new public entry would be created at the gymnasium for after-hours activities.

Our work supports the human condition, understands its potentials and frailties, and creates an environment that fosters inquiry, well-being and growth. We seek to understand the human condition and address those things that we, as human creatures, respond directly to - from physical comfort issues such as light levels, temperature, and humidity - to our emotional and psychological needs.
Project Description
The design concept for Lincoln Elementary School has been developed in response to Ellensburg School District’s Education Specifications and program criteria, existing site and campus conditions, various standards and regulations governing the project, and community expectations established by the 2018 school bond. Based on the significant residual value of the existing school building to the community and the District, the original 49,000 square foot two-story building, constructed in 1948-49 with a 1,000 square foot administration addition in 2014, will be remodeled and modernized to become a 21st century learning environment serving the Ellensburg community for decades to come. The project scope includes a new gymnasium, music classroom, and elevator additions totaling approximately 7,000 square feet of new construction.
The renovated school project is proposed as a 450 student, 57,000 square foot K-5 school located on the existing Lincoln Elementary site. The site is approximately four acres and urban-residential in nature. The renovated school will contain general classrooms, resource rooms, library, gymnasium, dining commons, kitchen, music room, administrative, counseling, and educational support spaces. Prior to the renovation work beginning at Lincoln Elementary, the students and staff will relocate to the District’s new elementary school at North Cora Street, north of the existing Mt. Stuart Elementary School. Students and staff will be temporarily housed at the new facility while the existing Lincoln Elementary structure will be abated and renovated. After completion of building and site renovations at Lincoln Elementary, students and staff move back to the renovated building.
Utilizing the work done during the generation of the Education Specifications as a starting point, the design team developed detailed testfit plan concepts with the new gym addition located to both the northeast and south of the existing building. After review with the District, the clear preference was for the new gym to be located to the northeast so that it can be zoned with the other more public functions of the dining commons and administration. Through the schematic design phase, multiple plan concepts were developed by the design team, reviewed with the District, and tested with Garco Construction, the project’s design-build contractor, to verify and validate the feasibility of the project’s scope.
Site & Building Organization
The existing elementary school is largely an “L-shaped” building with a long, two-story classroom leg running north-south and a one-story gym and music classroom volume running east-west on the site. At the intersection of the two historic wings, a single-story administration addition serves as a recent secure entry point to the school building. The main entry and main façade of the building face Sampson Street to the west. The school’s play areas are located to the east and south of the building. The new gym and music classroom addition to the northeast of the existing building create the opportunity for a new south facing courtyard off the new dining commons, which will be housed in the existing gym volume. A new elevator and secondary-entry addition will be located at the south end of the existing building to connect the school’s three floor levels.
The school’s site organization will feature automobile drop-off along the sidewalk on Sampson Street and bus drop-off along a new and enlarged sidewalk on Walnut Street. An expanded staff and visitor parking lot will be developed to the south where the existing parking lot and portable classrooms are located. While preserving the large “leafer” tree at the southwest corner of the site, the parking lot access will shift south to extend the length of the auto drop-off on Sampson Street. A new service and delivery area will be located at the northeast corner of the school with access off Walnut Street, eliminating the need for food service deliveries to cross the school’s play area. The location of the new gym and music classroom addition will create a new courtyard south of new dining commons. The courtyard will offer a calm and more introspective play area for students, increasing the diversity of recess activities available and maintaining a quieter area outside the new kindergarten classrooms inside the existing building. Reconfigured soft-surface play areas will be developed within the hardscape play areas to accommodate new and expanded play equipment, and the existing play field will remain in its current location to the southeast.
The school’s building organization will maintain and respect the historic character of the Mid-Century school building to the greatest extend possible. Existing classrooms will remain in their current locations, as much as possible, and renovated in a manner to preserve their character, while bringing them up to 21st century standards. Several of the existing building’s areas will be more extensively remodeled and reconfigured in order to achieve the goals and program stated in the Education Specifications. The library will be relocated to the ground floor where the original building’s kindergarten was located. It will be able to take advantage of the first-floor access and the large bay window projection that lends itself to a more public and shared function. Three first floor classrooms will become kindergarten classrooms with single occupant toilet rooms inside the classroom. A special education suite of classrooms and support spaces will be located where the school’s original cafeteria and kitchen is located, providing most of the specialist resources in a central location, affording the ability to easily collaborate. A new dining commons and kitchen will be located within the existing gym space with a mechanical and storage mezzanine located above the new kitchen. The existing music room and gym storage will be reconfigured to provide building support spaces and access to the new gymnasium and music classrooms. The new music classroom will be positioned so that it can serve as an elevated platform connecting to the gym.
Architectural Expression
The existing school building is a Mid- Century Modern two-story “L-shaped” structure clad in red, Roman brick. The building incorporates narrow, ribbon view windows with translucent panels in the classrooms to bring abundant daylight into the spaces. The brick, windows, and parapets give a strong
horizontal expression to the building. Several stairways and spaces utilized corner windows to add interest and hierarchy to the building’s expression. The existing gym volume, as well as several other spaces, have simple punched window openings common with load-bearing masonry construction
during that era. Some of the historic character, and horizontality, has been diminished over time with the replacement of the original glass block in the classrooms, the removal of the precast sills and lintels, and the infill of the expansive glazing in the original cafeteria and kindergarten spaces.
The new building additions will strive to be complimentary to the existing historic structure, rather than trying to match, or recreate, the existing building’s specific materials and colors. Using guidelines consistent with the preservation and rehabilitation of historic buildings, the new additions will be clearly differentiated from the original mid-century building. The new additions will take cues from the
existing building using masonry, vertical punched openings, and horizontal corner windows to create harmonious extensions of the existing building, which are enduring and true to their time.
Generally, the new building exteriors will consist of masonry, storefront window systems, and metal panel as appropriate, materials that are enduring, cost effective and easily maintained. Colors and tones will be warm and inviting and work well with the existing building’s materials, the materials will be sustainable and appropriate for an elementary school.
Sustainable Design
Sustainable design and resource stewardship are critical aspects to building a better future for the students that will attend Lincoln Elementary School, as well as the staff and faculty that will work at the school, over the coming decades. There are numerous sustainable design elements that play a role in making the project more sustainable and environmentally responsive, but perhaps none more significant than the reuse of the original school building built over 70 years ago. A rough calculation for choosing to renovate the existing building, rather than tear down and replace the school, shows the project will save over 1,000 metric tons carbon dioxide from being released into the world’s atmosphere. Carbon dioxide emissions are widely believed to be a major contributor to climate change.
One of the design features of the existing building that contributes to sustainable design and resource stewardship is the classroom daylighting. The windows and translucent panels, along with the high ceilings, bring daylight deep into the classrooms. Good daylighting levels have been shown to improve student performance, and good daylighting lowers operating expenses in new construction through the addition of daylight sensors that reduce the amount of electricity used for artificial lighting. The new gym addition will strive to also have great natural light to make the experience of using the space enjoyable and reduce the need for electric lighting during the school day. Energy efficient LED lighting will be utilized throughout the renovated building and new additions where there is not adequate natural light levels to dim or turn off the lights. Occupancy sensors will also be used to ensure that the lights are only on when necessary.
The project’s mechanical system will be highly efficient and improve indoor air quality through the direct outside air system (DOAS) and will improve occupant comfort though its efficient heating and cooling systems. Improved air quality and occupant comfort have been shown improve student performance and reduce student and staff absentee rates.
Water is a precious resource, and the project will seek to reduce the amount of potable water used to the greatest extent possible. Low flow plumbing fixtures and draught-tolerant landscaping will be used.
A significant aspect of the design team’s commitment to sustainability and occupant health is the use of healthy materials. Products that contribute to healthy indoor air quality and have low environmental impacts will be prioritized. Like daylighting and thermal comfort studies, good indoor air quality improves performance and decreases absenteeism. Part of the project scope, and critical to the reuse of the existing building, is the abatement of building’s hazardous materials, such as lead, asbestos, heavy metals, and refrigerants. Abating the building will ensure that there are no long-term health issues associate with the building, making the building a healthy place to inhabit.
Structural
Structural engineering informs the ways in which a structure can - and should - be built. Through analysis and design, we ensure that what we build is able to withstand the stresses and pressures of its environment; that it remains safe, stable, and secure throughout its intended use. Striving for an integrated solution that meets the needs of all involved, the structural engineering team provides the support necessary to take projects from concept to design to construction - and, ultimately, from vision to reality.
Structural Elements
I. Structural Elements
A. Foundations
Soil conditions on the Lincoln Elementary site consist of silt with sand (alluvial deposits) extending to a depth of between 1 ft. and 7 ft. below grade surface. Gravels with sand and silt are present beneath the alluvial deposits. The alluvial deposits will need to be over-excavated and the sub-soil will need to be remediated to support new footings per Geotechnical Site Investigation Report by GN Northern, Inc. dated September 2, 2020. Geotechnical recommendations for soil remediation include over-excavating to a depth and width 3 ft. beyond the extents of the footings and placing geo-textile between layers of compacted structural fill above 12 in. of compacted quarry spalls.
B. Slabs-on-Grade
Four-inch-thick concrete slabs-on-grade will support floor loading. Slab reinforcement will be designed to reduce crack width and to provide some distribution of loading. Thickened slabs will be provided as required for equipment loading or concentrated loads where the use of isolated footings or foundations cannot be justified. Slabs will be cast over a moisture barrier and a 6 in. gravel base on top of remediated soil. Geotechnical recommendations for soil remediated to support slab-on-grade is to compact a 12 in. layer of quarry spalls into the exiting soft soil.
The following structural systems are currently planned:
- New Construction — Roof Framing (Gym and Music)
Roof loads will be supported by 3 in. (20 gage) acoustic steel roof deck over open-web steel joists. The open-web steel joists will be supported by steel wide flange beams and steel columns. - Renovated Construction — (Existing Music Room/ New Custodial Receiving and Chair Storage)
The existing interior walls and roof structure at the existing music classroom will be demolished and replaced with new structure, leaving the historic brick walls as a veneer. Roof loads will be supported by 1-1/2 in. (20 gage) steel roof deck over wide flange beams. Where mechanical loads are required to be supported, the wide flange beams will be sized to support the additional load. - Mechanical Mezzanine above New Food Service in Existing Gym
The new mechanical mezzanine above the food service area will be a concrete-on-metal-deck floor supported on composite steel wide-flange beams and steel columns. The mechanical mezzanine will be structurally isolated from the existing gym walls. New supporting foundations will be necessary in the existing crawl space. - New Floor above Existing Boiler Room
The existing boiler room equipment will be demolished, and a new floor system will be installed at the same level as the existing first floor. The new floor system will be concrete-on-metal-deck supported by composite steel wide flange beams and steel columns. - Elevator Shaft Addition
A reinforced CMU elevator shaft will be added off the south end of the corridor. The at-grade entrance will have a slab-on-grade floor. The elevator lobbies at the main level and second level will be concrete-on-metal-deck floor supported on steel wide-flange beams and steel columns. - Lateral Systems (New Construction)
Lateral loads imposed by wind and seismic forces on the new gym and music addition will be resisted by horizontal roof diaphragms and steel braced frames. Loads imposed on the re-structured music portion of the building will be resisted by a new internal steel frame system. A seismic isolation joint will be added between the existing music room and the existing gym. The mezzanine above the food service will resists lateral force through steel braced frames. The elevator addition on the south end of the building will be seismically isolated from the existing building. Lateral forces will be resisted by the CMU walls of the elevator shaft. - Existing Building
The existing building structure is analyzed and retrofitted in accordance with IEBC 2018, Level 2 Alterations. The existing building structure will remain intact to the extents possible. Where the existing lateral load carrying structure is not impacted by an increased demand to capacity ratio of more than 10%, seismic upgrades are not required. However, localized seismic retrofit items will be voluntarily applied throughout the building to improve seismic performance of the unreinforced masonry building. Where a lateral load carrying element is greatly impacted, new structural steel braced frames, meeting the requirements of IEBC, will be added.
D. Exterior Walls
The new construction portions of the project will have curtain walls and storefronts. The exterior walls will be supported laterally by floor and roof framing. Vertical support will be provided by concrete foundation walls. Exterior finishes will be laterally supported by light gage steel studs spanning vertically from floor to roof. The existing portion of the building will have minimal changes to the exterior walls.

HVAC Approach
The school district is required to analyze three systems for the energy life cycle cost analysis (ELCCA). Three options are being analyzed in the ELCCA are identical to the systems evaluated for new Ellensburg Elementary and Mt. Stuart. We do not expect different results than the previous schools analyzed and are basing our current design on the same 4-pipe fan coil system to standardize on system maintenance, operation and troubleshooting district-wide.
Current Approach (4-pipe fan coils, ceiling mount, ducted):
Classrooms: 4-pipe fan coils ducted to the classroom. For the first floor classrooms, we are proposing a new soffit near the corridor to preserve the current classroom ceiling height. On the second floor, the fan coils are proposed to be housed within the existing accessible attic. Filter return grilles will be provided to facilitate routine filter changes and prevent substantial attic access. A dedicated outside air unit (DOAS) with heat recovery and demand-controlled ventilation will be provided and ducted to each space. Demand controlled ventilation will be regulated through pressure independent controls consisting of electronic dampers and airflow sensors.
Gym: Single zone air handling unit with hot water coil, chilled water coil, filters, and a mixing box for air side economizer and demandcontrolled ventilation. (7,600 cfm supply and 3,000 cfm outside air +/-).
Commons: Single zone air handling units with hot water and chilled water coils. The space ventilation will be provided from a DOAS unit and controls will be equipped with demand control ventilation. (7,000 cfm supply).
Kitchen: The kitchen will be served by a fan coil with hot and chilled water coils and outside air. Makeup air for kitchen exhaust will be provided by the kitchen fan coil and the commons air handling unit by transferring air between the commons and the kitchen.
Main Electrical Room: 4-pipe fan coil unit with economizer cooling.
MDF/IDF: Ductless split systems will be provided in these spaces to maintain temperature year round.
The heating water system will be provided from a central natural gas fired heating plant with 90% efficient condensing boilers supplying 140° water. The plant will contain two high efficiency gas fired boilers-each sized for 60-70% capacity each. The heating distribution system will be piped with constant flow through the primary boiler loop and variable flow through the secondary loop. Heating water circulation will be provided by two redundant floor mounted pumps with VFDs to reduce energy consumption. At this early stage, the system capacity is anticipated to be 1,500 MBH with 150 GPM and 4 in. main heating loop.
The cooling system will consist of one air cooled chiller with scroll compressors and will located in an equipment yard. The chilled pump will be variable flow by using a VFD, floor mounted and sized for 100% capacity. At this early stage, the system capacity is anticipated to be in the 175 ton range with 250 GPM and a 6 in. main chilled water loop.
Water Treatment
For hydronic systems, provide high efficiency air/dirt separator in each closed loop hydronic system. Introduce chemicals through the glycol feeder and/or pot feeder. Introduce propylene glycol to heating and cooling systems through glycol feeders with 30% inhibited propylene glycol solution.
Air & Hydronic Balancing
Systems shall be completely balanced to ±10% of design values in accordance with Associated Air Balance Council or National Environmental Balancing Bureau. Balance will be performed under a separate contract direct with the Owner.
Indoor Air Quality
DOAS and Air Handling Unit Air Filtration: 2 in. disposable thick pleated media 30% efficient pre-filters (MERV 7) and 2 in. thick 80-85% efficient final filters (MERV 13).
Fan Coil Filtration: 2 in. disposable thick pleated media 30% efficient pre-filters (MERV 8).
General Exhaust: Maintain a minimum of 8-10 air changes per hour exhaust in toilet rooms, custodial rooms and locker rooms.
Ventilation: in accordance with Washington State Code, and ASHRAE Standard 62.1 plus specific exhaust makeup air requirements.
Separate building air fresh air intakes from exhaust.
The building facility personnel shall have the ability to override the DOAS and air handling unit ventilation controls to shut off outside air to the building when the outside air quality is not acceptable such as during roofing projects or area fires.
Acoustics
Systems will be designed and installed to meet the maximum noise criteria (NC) established for each space use. Special acoustical considerations of the mechanical systems will include locating air compressors away from acoustically sensitive areas and limiting the noise effects of the air-cooled chiller on adjacent spaces. Where this is not possible, acoustically treated walls will be required.
Additional acoustical considerations will include limitation of duct velocities through ductwork,
terminal units and air inlets/outlets to achieve space NC, use of sound attenuators in the duct systems, and vibration isolation of mechanical equipment with spring isolators and flexible
connections.
Ducts will be sized with a maximum air velocity of 1500 FPM.
- Halls, Corridors and Lobbies: 35-45 NC
- Private Offices: 25-35 NC
- Classrooms: 35 NC
- Libraries: 25-35 NC
Building Automation System
The building will have direct digital controls (DDC) provided by one of the followed approved vendors: Siemens (base bid), Alerton (alternate bid) as extensions to central systems currently maintained by the district. Wireless controls are not allowed. Control manufacturers will bid competitively during the bidding period. Communications protocol will be BACnet except Siemens will be P2.
Damper and valve actuators shall be electronic with Siemens or Belimo actuators. Room thermostats shall be electronic wall sensors locally adjustable in all classroom and office areas.

Washington State Sustainability Protocol
- Schematic analysis shows reusing the existing Lincoln Elementary School building cuts the embodied carbon footprint by half
- One of the most sustainable aspects of the Lincoln Elementary School project is preserving the existing community asset while bringing it up to modern day standards
- Daylight modeling analysis quantifies the exceptional daylight performance of the existing Lincoln Elementary School teachers and students already understand experientially
- Nearly all classrooms receive nearly 100% spatial daylight autonomy* [Spatial Daylight Autonomy (sDA) describes how much of a space receives sufficient daylight. Specifically, it describes the percentage of floor area that receives at least 300 lux (30 foot-candles) for at least 50% of the annual occupied hours.]
- Good daylighting has been shown to improve math and reading progression, as well as overall academic performance
- Using modeling software the design team is striving to make the new gym addition as well day lit as the existing building
Building Materials
- New materials will be selected with the health of the occupants and the planet in mind

Programs
Occupational Therapy (OT)
School-based occupational therapy practitioners are occupational therapists (OTs) and occupational therapy assistants (OTAs) who use meaningful activities to help children participate in what they need and/or want to do in order to promote physical and mental health and well-being. Occupational therapy addresses the physical, cognitive, psychosocial and sensory components of performance. In schools, occupational therapy practitioners focus on academics, play and leisure, social participation, self-care skills, and transition/work skills.
Physical Therapy (PT)
School-based physical therapists (PT) are part of a team of related service providers who support a student’s ability to access his/her educational environment. As specialists in movement, they assist a student’s physical participation in a variety of settings throughout the school day. The primary role of the school PT is to help students benefit from their educational program within the educational environment.
Physical therapy is provided at schools only when it is related to educational needs. Intervention and goals in the school setting address the child’s functional needs in accessing all areas of the school curriculum. Physical therapy interventions are designed to enable the student to travel throughout the school environment; participate in classroom activities; maintain and change positions in the classroom; as well as manage stairs, restrooms, and the cafeteria. School-based therapy is not intended to meet all of the therapeutic needs of a student; rather it is intended to ensure that a child can have physical access to his or her education.
Resource Rooms
Resource Room I
The Resource Room I is for students with identified disabilities who demonstrate primary learning needs in the academic domain or in adaptive skills. They may need intensive, specially designed instruction to learn how to read, write, and solve mathematical calculations and problems. They may have special needs in social-emotional and/or functional life skills domains as well.
Resource Room II
Resource Room II is provided for students with identified disabilities who demonstrate an increased need in one or more domains. Students receiving learning resource center support, receive half or more of their daily instruction through general education, along with specially designed instruction in learning areas or other areas of identified need.
Speech Therapy
Speech therapy is an intervention service that focuses on improving a child's speech and abilities to understand and express language, including nonverbal language. Speech therapists, or speech and language pathologists (SLPs) provide these services.
Title
Title I, Part A is a federal program designed "to provide all children significant opportunity to receive a fair, equitable, and high-quality education, and to close educational achievement gaps" and serves the unique needs of children K-12 who struggle to learn. Title I programs and services provide customized instruction and curricula that helps these students meet academic standards and take an active, engaged interest in what they learn and can do. As the oldest and largest federal education program, Title I, Part A programs build equity of opportunity for children whose struggles often keep them on the academic sidelines.
Progressive Design Build
Why the PDB Contract Procedure is Appropriate for the Lincoln Elementary Project
For the Lincoln Elementary School the construction delivery method will be the Progressive Design Build (PDB) Contracting model. This method allows for the District to hire one contractor and designer who will team with the District to provide their construction expertise through the design, permitting, and construction phases. The project has some demanding features that will need the contractor’s input.
The age, layout, and condition of the existing school structure cannot adequately support the program needs of the District. The structure will be brought up to current energy codes by upgrading the wall systems on the interior of the building. The structure will also need to be brought up to current seismic regulations. Abatement will be completed for the entire facility, and a completely new Mechanical, Electrical, and Plumbing system will be installed to replace the existing infrastructure, to include fire suppression. Also, one of the most beneficial results from the Design Build delivery is the ability of the contractor to collaborate with the designer to increase the design efficiency and constructability of the project as it relates to these highly specialized activities.
The current structure was constructed in 1949, with minor upgrades completed over the life of the structure. This presents many complications and unknowns throughout the structure. The PDB team will help bring new and innovative ideas and thoughts to the facility that the District may not be aware of. The creativity of the PDB team will be instrumental in the development of the renovated facility to provide the most efficient and technologically appropriate building.
By utilizing PDB, this will allow the design team to accelerate the design timeline, and allow the beginning of the site package before the building design is 100% complete. By accelerating the schedule, it will allow the team to start construction of the additional space prior to students leaving school for the summer break. Once summer break begins, the students will be moved out of the building for one year allowing construction in the existing structure to be reduced to one year and allowing the students back in the school for the fall of 2022. PDB also allows the District to lock in the project amount early and avoid some cost escalation. In addition to locking in the budget early, utilizing the outlined schedule will allow strategic timing of the bid packages to get the best value for the various scopes of work. The PDB team will also provide valuable constructability reviews, bring Value Engineering options to the table, and be able to identify long lead procurement items to stay on pace with an aggressive schedule.
In addition, it is important to point out, once the Guaranteed Maximum Price (GMP) is set, the risk of the final project cost exceeding the approved GMP, due to unforeseen change orders, is greatly reduced over other delivery methods of similar size and scope. With PDB the Design-Builder assumes risk of change orders from errors and omissions in the documents, not the Owner. The exception would be the discovery of significant unknown subsurface site conditions or Owner directed increases to project scope. PDB is the best way for the District to stay within the budget and maximize value.
The ability for the District to choose the team based upon qualifications rather than low bid in a very hot market is key, as it is not desirable to have a contractor who is not qualified or experienced.
Parents, Staff, Students and Community Members,
The Ellensburg School District Board of Directors authorized a bond proposition to be placed on the November 6, 2018, special election ballot to alleviate overcrowding and address critical safety and maintenance concerns at the elementary school level. This plan will add space, build a replacement Mt. Stuart Elementary, and renovate Lincoln Elementary, and build a new elementary school on newly purchased property on the northwest side of town.
