GENERAL INFORMATION

1.2 SITE CONCEPTS

The proposed middle schools in this construction package will be located at the west and south sites. A new elementary school will also be located at the south site with the middle school to create a campus-type development for Liberal USD 480.

• Pine Street Site (South): Includes the new south middle school and related site amenities and a new elementary school with parking for about 100 cars and related outdoor play facilities.

• Western Site (West): Includes the new west middle school, parking for about 300 cars, track and fi eld, separate practice fi eld, and related site work.

SITE GRADING AND DRAINAGESite drainage will be directed overland to a combination of ditch sections and enclosed storm drain strategically located throughout the site site areas. Storm water detention is anticipated to be required and will be confi rmed with a storm water management study per city of Liberal public works requirements. Detention would be located within new or existing dry, shallow detention ponds. Refer to the civil engineering portion of the SD narrative.

Proposed building additions will have internal roof drains that will be connected to the existing storm drain system. A Storm Water Management Plan will be prepared during design development for this project. Proposed grading will work to balance cut and fi ll for both sites and erosion control measures will be in accordance with the city of Liberal and Kansas State Standards and Best Management Practices for erosion and sedimentation control.

LANDSCAPE ARCHITECTUREA. Proposed Landscape Plantings: New plantings and street trees will be provided as required by the City of Liberal. School entries will be planted with shade trees and ornamental trees with a few planting beds of shrubs and native grasses to create an inviting entry experience for school patrons and students. Planting beds will be mulched with durable hardwood mulch and edged with bed edging to reduce maintenance. A chemical weed barrier will be installed under and over the proposed shredded hardwood planting bed mulch material to prevent weed growth.

B. The open site areas used for storm water detention and other areas not used for playing fi elds will be seeded with native herbaceous prairie plants and native grasses. The intent is to re-create the natural beauty of the Kansas prairie and minimize the need for mowing, fertilization, and watering.

C. All lawn areas adjacent to the proposed building will be sodded with a drought tolerant, tall turf-type Fescue grass blend.

D. Irrigation: An automatic irrigation system will be provided for the natural turf play fi elds. Supplemental watering of turf and plantings outside of the irrigation zones

GENERAL INFORMATION CONTINUEDATHLETIC FIELDS AND TRACKA. Running Track: An eight-lane asphalt track with ½” polyurethane surface and structural spray system will be provided with striping meeting State High School Association requirements. Includes an inside perimeter track slot drain. Other track events including Long/Triple Jump, Pole Vault, Discus, and Shot Put will be located adjacent to the track. High Jump will be located inside the track “D” area.

1. New high jump areas at the north and south ends of the track; 2. One long/triple jump with two jump pits; 3. Pole vault landing pad and runway. 4. Install track timing and communication cables in communication boxes within the fi eld surfacing to accommodate track timing and photo fi nishes.

B. Natural Turf Football and Soccer Practice Fields: Construct the athletic fi eld with a well-drained soil mix and perimeter sub-drainage system. Install the following additional improvements:

1. A combination football/soccer goal system will be provided in the turf fi eld per NFHS standards. 2. Scoreboard and fl agpole outside of the track. 3. Football play clocks within the high jump concrete curb area. 4. Install communication boxes for potable water for the players, electric outlets, and track timing and communication system. 5. Install 6-feet height galvanized fencing in locations shown on the drawings around the track and fi eld for crowd control during games and to keep vehicles off of the fi eld areas.

C. Aluminum Grandstand: Construct a 500 seat aluminum grandstand on the home side.

CIVIL ENGINEERINGA. Pine Street Site 1. This site will need to be platted, overriding the previous platted subdivision in this area.

2. Utilities: • The existing lift station located at the north east area of the site (near Griffi th Avenue and Charles Street) will need to be upgraded, according to the City. This will fall under the School’s design and bidding services. Further investigation is needed to confi rm the need for upgrading.

• Sewer - Sewer lines will need to be relocated as well, since they were installed to serve as residential development that has yet to occur. The City will be providing the design and bidding for the sewer projects. Any easements will need to be vacated as part of the platting process.

1.2 SITE CONCEPTS

• Water - A water main will need to need relocated in a couple of areas, as they were also installed to serve a residential subdivision. The city will design and bid this relocation project.

• Power - Overhead power lines are currently crossing the proposed school site. These lines were also installed to serve a future subdivision. The lines need to be relocated. Coordination will need to be made with Southern Pioneer. Regardless, power is available to the site.

• We will need to check with AT&T, Zito (cable), and phone for service to the site. Fiber optic is not in the area.

• Gas - According to Black Hills Energy gas is available to the serve the site.

3. Griffi th Avenue will need to be extended to serve the east side of the proposed site and will be designed and constructed by the school district. Sidewalks will be required to be installed along the west side of the Griffi th extension.

GENERAL INFORMATION CONTINUED

1.2 SITE CONCEPTS

CIVIL ENGINEERING CONTINUED 4. Access is anticipated from the extended Griffi th Avenue, Hickory Street, and Walnut Street.

5. A pavement impact study will be required. The study will focus on the travel paths and the impact the traffi c will have on the current street structure. Some streets (Hickory, Walnut – last couple of eastern blocks, and Warren) only have a chip and seal structure. Bus traffi c will damage these streets after a short time and chip and seal is not intended to support a lot of standard vehicle traffi c.

6. Detention - The City has stated detention will be required for the proposed improvements. We understand the detention facility could be placed south of our site, as the developer to the south will modify the facility in the future when he develops the site. Although fi ll will most likely be placed in the fl oodplain for the control structure, more earth will likely be removed for the detention containment volume resulting in a net loss of earth in the fl oodplain. The City would fi le the necessary documents to FEMA for the permit. Detention could also be placed on- site for the school improvements only.

B. Western Site 1. The site will require platting, a drainage study, and a traffi c impact study.

2. Access is anticipated from Western Avenue.

3. The site has a blanket gas easement. The gas company will need to be contacted to vacate the blanket easement. Gas line should be able to be relocated to stay away from the school. The natural gas line runs along the western part of the site.

4. Coordination with FAA will be required prior to construction of the site to ensure building height and equipment height will remain below FAA’s height restrictions.

5. ONEOK has a high pressure pipeline clipping the S.E. corner of the site. We will need to have tight coordination with ONEOK to ensure we avoid confl ict with the proposed sanitary sewer service line and drainage design items (detention and storm systems).

6. Detention - Drainage runoff can be conveyed from the site to the “fi gure 8” detention facility south of the site (and increase the size of the detention facility – school district can use the fi ll) if the desire is to not have detention on-site. The City has an easement along the west side of Western Avenue which could be used to convey the storm runoff from the site to the detention facility, if the easement is wide enough. The runoff could be conveyed in an open ditch or through a storm system. Detention could be placed on the school site as well. Engineering Analysis to provide the most economical solution.

7. Traffi c – We understand a traffi c study is needed to evaluate the impact the proposed school traffi c will have on the existing traffi c on Western Avenue. The traffi c study will determine if any improvements are required to the geometrics of the roadway, or if traffi c signals are required.

8. Utilities – • Water - A 14-inch water main exits along the west side of Western Avenue. The City states the line should have enough pressure and fl ow to serve the site.

• Sewer – the City is designing and will be installing a new sanitary main to serve the proposed Western site. We understand this line will be installed deep enough to gravity fl ow the sewage from the new school.

• Power – Power line exist along the west side of Western Avenue and can serve the site

• Gas – According to Black Hills Energy gas is available to the serve the site.

DISCOVERY COURTYARDSAs a site plan feature to the ES Prototype, Discovery Courtyards are located adjacent to the Media Center and surrounded by building on three sides. This courtyard is a place for an outdoor learning classroom or simply a quiet place to read and enjoy the outdoors. These areas can be uniquely themed post-construction through the collaboration of the community & students.

GUIDING PRINCIPLES OF ES & MS DESIGNS

ES PROTOTYPE DESIGNThe design team has developed the proposed schematic design to meet the challenges and implement the guiding principles of design. The new elementary prototype will use the latest technology to reinforce the District’s emphasis on creating a 21st century school that serves the community, meets the needs of the students and provides a safe place for learning.

As established during the Visioning Meetings, the prototype design is organized around two grade level neighborhoods and delineation of community use spaces from classroom spaces. These ideas reinforce collaboration within classroom neighborhoods and promote community integration in the school. Classroom neighborhoods are organized around a fl exible Discovery area that provides additional educational space for students. These open, technology-fi lled Discovery areas take on a unique and identifi able character for each neighborhood. Natural daylight and views to an outdoor learning courtyard promote a positive learning environment.

The location of the commons, gymnasium, and media center allows for community use outside of school hours. Centered on the commons, the music room also serves as a stage for school or community performances. To further the fl exibility of the commons, an operable wall separates the gymnasium from the commons. This allows for a greater variety of uses for the students and community.

A safe and secure entry is established through the location of the administration. Visitors are directed through a reception area before gaining access to the school. A parent center adjacent to the administration provides a place for parents to interact and connect with the staff, administration, and each other. This unique space also facilitates parental involvement with the students.

Three distinct spaces in the new elementary school are centrally located within the building plan. The media center, art, and music rooms all provide a unique learning environment. These spaces become a focal point in the design of the school through their location, building massing, and material treatment.

Strong, durable materials clad the exterior of the building. A blend of masonry, metal panel, and glazing in key locations defi ne the functions within and create an inviting and aesthetically pleasing school. Natural daylight and views are provided in all classrooms to enhance the learning environment.

COMMUNITY CHARACTERISTICSThe design team established key areas of the elementary school prototype that respond to each distinct school community. The Discovery Courtyard and the Community Courtyard take on a unique design related to the community in which the school resides. The exterior building materials also distinguish the individual school. Through the use of the color and pattern, a unique aesthetic defi nes each building.

Within the school, interior materials also establish a character that responds to the school’s community. Material pattern, color, and fi nish express a unique aesthetic for each individual elementary school. Through these elements, each prototype school takes on an individual character that responds to the community in which it resides.

The interior of the elementary schools will be a positive and creative environment that serves as a learning tool for students, the community and visitors. The interior will have a comfortable, fun and cool vibe through the use of innovative materials, textures and colors.

Each school will have established individual character that responds to the community in which it resides. This will occur through the placement of color and materials. Material fi nish selections will be durable and easy to maintain.

FLOOR FINISHESThe Main Corridor will have polished concrete. The Administration, Media Center and Music room will have carpet tile. The Commons Area will have resilient fl oor tile, while the Gymnasium will have resilient athletic sheet fl ooring. In the Kindergarten, First, Second, and Third Grade Classrooms, the fl oor fi nish will be carpet tile and resilient fl oor tile. The Fourth and Fifth Grade Classrooms will also have resilient fl oor tile. The Discovery Areas and Classroom Corridors will have a combination of carpet tile and resilient fl oor tile. In the Kitchen and rest rooms, the fl oor fi nish will be epoxy resin.

WALL FINISHESLobbies, Main circulation and Commons will have painted gypsum and painted concrete masonry units. Wall materials throughout classrooms neighborhoods will be high impact resistant wall board for durability. Decorative tack walls will be provided in key locations such as corridors, media center, and discovery areas. Painted wood fi ber board acoustical panels will be used in the gymnasium and

commons as needed to make the spaces acoustically comfortable. Rest rooms will have wainscot ceramic tile on wet/plumbing walls.

CEILING FINISHESThe ceilings will be 2’ x 2’ suspended acoustical panels with high NRC in Classrooms, Main Circulation corridor, the Media Center, Classroom corridors, Discovery Areas, Administration, and the Music classroom. Gypsum board soffi ts and bulkheads will be used in key locations throughout the building to defi ne a sense of entry and divide ceiling planes and heights. Some spaces will have exposed structure with fl oating acoustical clouds, such as the Corridors, Commons and Discovery areas. Some rooms may have exposed structure with no ceiling, such as the Art room, electrical and janitor closets, mechanical, and other rooms where ceilings are not required for the aesthetic or sound transmission purposes.

BUILDING CONCEPTS

THE MIDDLE SCHOOL VISION MS PROTOTYPE DESIGNDLR Group’s Liberal Middle School project team set out to design a new middle school for 6th through 8th grade students and staff. The building is organized to address a variety of issues and concerns, as well as building uses and teaching methods, that were identifi ed by the School District and DLR Group’s project team.

The circular Media Center sits at the core of the building, with a round-about corridor branching into radius hallways leading into academic wings and the public, community, and common spaces. Separate drives for bus and drop-off traffi c each have an entrance into the common areas of the building. Students arriving in the morning will enter one of the entrances and will go to the centrally-located commons area before classes begin. 6th graders will travel around one side of the roundabout corridor into their academic wing, while 7th and 8th graders travel the opposite side of the roundabout into their wing. Each academic wing houses Core Classrooms, Science Prep and Storage, a Teacher’s Planning Center, Resource Room, Computer Lab, a Small Conference Room, and two banks of restrooms. The academic wings are essentially self-contained, achieving separation of the 6th graders from the 7th-8th graders.

On the opposite side of the Media Center core are the building’s public, administrative, and elective spaces. Administration is located at the front entrance to the building to allow for proper supervision of the entrance, as well as convenient access from all areas of the building. The Commons area is also at the heart of the building and will serve as the eating area, a place for students to congregate before classes begin, and a gathering area for student or public activities. The Music Classroom rooms are located adjacent to Administration Suite. An 800-seat competition gym, support spaces, and a weight room are located at the north entrance. This allows for easy parking and after hours access for events and practices.

Elective classrooms, including FACS, Industrial Tech, Music, and Art are all centrally located off the Media Center roundabout corridor. This arrangement provides maximum program fl exibility and convenient access.

Special Education classrooms are located throughout the building. Inclusive program classrooms are near the building’s core, with additional classrooms for pullout and speech programs in each academic wing.

14

Staff support spaces are plentiful, and designed to meet the planning, preparation, and training needs of teachers and staff members. In addition to a Teacher’s Planning Center in each academic wing, staff will have a separate dining/lounge area adjacent to the Commons area and Cafeteria, and a Forum Room between the academic wings designed to accommodate large training sessions or meetings.

The new Liberal Middle School is designed to meet the growing functional needs of the District’s staff and students, while providing the fl exibility necessary to accommodate various teaching methods and a variety of student and staff activities.

EXTERIOR BUILDING MATERIALSThe exterior building materials will be modifi ed through the use of color and pattern of the materials listed below to distinguish a unique and aesthetic defi nition of each building for the individual schools.

The exterior building will be constructed of brick veneer on concrete load bearing masonry units, with two or three colors of brick incorporated in the design for accent. Precast concrete or cast stone will be used at windowsills and lintels for added accents to the façade. At the two main entrances and the Media Center clerestory, storefront or curtain wall system with metal panels above shall be incorporated to accent these key building elements.

The front entrances and commons area curtain wall systems shall have tinted glass to accent the building colors. Either storefront or aluminum windows will be strategically located in classrooms, the administration area, and other areas that require adequate natural lighting. The roof membrane will be a modifi ed bitumen roof system.

INTERIOR BUILDING MATERIALSThe interior building materials will be modifi ed through the use of color and pattern of the materials listed below to distinguish a unique and aesthetic defi nition of each building for the individual schools.

The majority of the building’s interior spaces will consist of concrete masonry walls. In the administration, media center and other areas with minimal threat of abuse, walls will largely be constructed of drywall over metal studs. Select interior public spaces will be accented with wood and, in some cases, exterior building wall materials.

The classroom wings, Media Center and administration will have carpeted fl oors. The Commons and central circulation corridor fl oors will be covered with an easily maintained vinyl product. The gymnasium will have a traditional cushioned maple plank fl ooring system. The restrooms and food service areas will be fl oored with quarry or porcelain tiles. Locker and shower rooms will have seamless epoxy resin fl ooring systems. Stained concrete will be used for the art, forum and science

classroom fl oors. There will be sealed concrete in the janitor’s closets, mechanical rooms, electrical rooms, and throughout building services areas.

The majority of the interior partitions will be painted. There will be wallcoverings applied in select administration areas. Classrooms and corridors will have tackable surfaces and markerboards.

Most ceilings will be a highly absorbent 2’ x 4’ acoustical tile. There will be exposed structure ceilings in the art classrooms, gymnasium, janitor’s closet, electrical rooms, and other areas where ceilings are not required for aesthetic or acoustical purposes. Restrooms and shower rooms will have epoxy painted drywall ceilings for moisture control. There will be a combination of painted drywall soffi ts and acoustical ceilings in the corridors and public areas such as the media center, commons and administration.

GENERAL OVERVIEWThe new Liberal Middle School Prototypes will be a one-story structure. The design will include an area of last resort (AOLR) for increased occupant protection during severe wind events, the structural design of which will be based on ICC 500-2008.

The new Liberal Elementary School Prototypes will consist of both one-story and two story components. The design will include an area of last resort (AOLR) for increased occupant protection during severe wind events, the structural design of which will be based on ICC 500-2008. STRUCTURAL SYSTEMS DESCRIPTIONA. Roof Systems: The roof framing systems at both schools will typically be a 1½” x 20 gage wide rib (Type B) painted metal roof deck supported by open-web steel joists and structural steel beams spanning between a combination of load bearing masonry walls and structural steel beams and columns. 3” x 22 gage Type N painted metal roof deck is anticipated to be used in the gymnasiums of both schools. Metal deck spans in the gymnasiums are anticipated to be 8’-0” to 10’-0”.

B. Floor Systems: At the Elementary Schools the typical elevated fl oor framing system will consist of a 3” thick reinforced concrete slab over 3” x 20 gage composite metal deck (6” total thickness) capable of spanning 8’-0” to 10’-0” between steel beams. Typical steel beams will be designed with headed studs to engage the slab in a composite manner to reduce steel costs. The typical fl oor framing will be supported by a combination of load bearing masonry walls and structural steel beams and columns. The fl oor framing over the area of last resort will either be a composite structural steel system as described above, with an additional 3” of concrete (9” total thickness), or a system consisting of precast hollowcore planks with a topping slab. The walls at the area of last resort will be either reinforced concrete or fully grouted masonry. Concrete walls at the perimeter of the area of last resort will be a minimum of 8” thick. Masonry walls at the perimeter of the area of last resort will likely need to be a minimum of 12” thick.

C. Foundation Systems: Foundations at both schools will consist of isolated and continuous shallow foundations that bear on suitable soil materials prepared as recommended by the project geotechnical engineer. All footings and foundations will be cast-in-place concrete and reinforced with ASTM A615 Grade 60 reinforcing steel. Perimeter trench footings will extend to frost depth as required by the building code and as recommended by the project geotechnical engineer. Slabs on grade will be a minimum of 4 inches thick and reinforced with welded wire reinforcement. Slabs on grade will be placed over a 15 mil vapor retarder placed on a minimum of 4 inches of granular drainage fi ll over the subgrade prepared as recommended by the project geotechnical engineer’s report.

D. Lateral systems: Resistance to wind and seismic lateral forces will be provided by ordinary reinforced masonry shear walls at the Middle Schools and by steel concentrically braced frames at the Elementary Schools.
