OVERVIEW

The new athletic wing at the Pittsburg Middle School is an opportunity to provide state of the art athletic facilities to the school community. This wing will include a new gymnasium and weight room in addition to support spaces such as girl’s and boy’s locker rooms, a team room, and a training room. These spaces are all within a modern building addition that creates a bookend to the existing building anchored by the large volume of the gymnasium.

In addition to these programmatic uses, the new addition will include designated storm shelter areas in the locker rooms. These areas can be used by the whole school, providing a place of refuge in a time of emergency. Using structural precast concrete building components for the walls and roof, these spaces are designed to meet the storm shelter requirements while still providing functional spaces in support of the gymnasium and the nearby exterior play field.

Located at a distance from the existing building, the landscaping will re-create the street as it connects to the surrounding grid to the north. This serves to draw pedestrians into the connector component as an access control point for the play field to the south. Double doors on either end of the connecting corridor allow the new addition and the existing building to be closed to the public to accommodate after-hours access by the public. This addition will be a much needed resource for the Pittsburg Middle School and the local community.

SITE CONCEPT Civil

MKEC has evaluated the existing site conditions and proposed site improvements for the building addition to the existing Pittsburg Middle School located south of E 14th St between N Broadway St and N Joplin St in Pittsburg, Kansas. The site plan consists of a new gymnasium addition, courtyard improvements, drop-off lane and parking lot improvements. A. DEMOLITION Demolition for this project will consist of removing: • City street vacation (N Elm St & E 13th to Joplin St)

o Relocate overhead powero Relocate gas mainso Relocate underground telecommunications

• asphalt pavement • concrete pavement • concrete curb & gutter • concrete sidewalks • trees & landscaping B. GRADING AND DRAINAGE The site generally drains from northeast to southwest. The proposed gymnasium addition will impact this drainage pattern so additional grading and new storm sewer will be required north of the gym.

The gymnasium addition will remain at the same finished floor elevation as the existing middle school.

Storm water detention is not anticipated for this site.

The site is not located in a FEMA 100 year floodplain. C. UTILITIES

1. Storm Sewer New storm sewer is anticipated to drain the proposed courtyard areas that will be created in the

vacated Elm St. corridor. The proposed storm sewer will connect to the existing storm sewer systems located at the intersections of Elm & 14th and Elm & 13th. Trench drains and Nyloplast drain basins are anticipated throughout the courtyard areas.

The storm system structures will be a combination of concrete structures and Nyloplast drain basins. HDPE pipe will be used wherever possible. When HDPE pipe cannot be used, RCP will be used.

The building roof drains will be collected via a storm pipe system and be routed underground to the storm sewer mains.

2. Water A new 8” water main is anticipated to be extended from a 12” City main at Joplin St west along

13th St. and feed new fire hydrants south of the gymnasium addition. Any new domestic or fire lines will be pulled off this new 8” line.

3. Sanitary Sewer An existing 8” (size per City information) sanitary sewer runs east to west within the 14th St.

right-of-way, just north of the gymnasium addition. Any new sanitary sewer services will need to extend north and connect to this main.

4. Dry Utilities Overhead electric and telecommunication lines will be relocated as part of the Elm St. vacation

process. An existing gas meter is located at the southeast corner of the existing middle school and is served from a gas line along Elm St. The service line may need to be relocated for the new gym addition.

New gas, electric, cable and fiber optic line costs should be planned for at this time. D. PAVING

1. Pavement All drives and parking lots will be concrete curb and gutter surrounding asphalt pavement. The

pavement design will be provided by the geotechnical engineer. Sidewalks will consist of 4 inch thick unreinforced concrete and will meet American’s with Disability Act (ADA) guidelines for accessibility. Loading areas and delivery lanes will have reinforced concrete pavement.

SITE CONCEPT Landscape Architecture

A. Proposed Landscape Plantings: New plantings will be provided as required by local design ordinance. New plant materials will be selected based on their performance and overall hardiness within their zones.

B. The new gameday sidewalk connection will run north-south and serve as pedestrian circulation from E. 14th Street through the new building corridor and back out to the existing football field. This will be a widened sidewalk that will incorporate decorative integrally colored pavements, site furnishings, and colorful landscape to create an inviting experience to students, parents, and guest.

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

D. Irrigation: An automatic irrigation system will be provided for establishment of the front lawn and planting areas near the front entry. City water is proposed to be used by the irrigation system. The water will be separately metered with a backflow preventer per local codes. The irrigation system will be designed to be sustainable with “Smart Control” will be provided as an alternate to provide additional water savings by limiting water to planting areas on an as-needed basis. The system will be able to detect water needs based on soil moisture conditions, rain/freeze shut-down, wind and other conditions.

Supplemental watering of turf and plantings outside of the irrigation zones will be manually watered with hoses attached to building hose bibs or quick connects located along the irrigation mainline. Areas of irrigation will be coordinated with the District during Design Development.

E. Site Furnishings: Benches, bike racks, and waste receptacles will be provided at the main entry as coordinated with District staff.

STRUCTURAL I. Overview

The Pittsburg Middle School Addition project consists of a new one-story athletics addition located to the east of existing middle school. The addition will be separated from the existing building by approximately 65 feet, but will be connected by an enclosed corridor. The addition will include a competition Gymnasium, Locker Rooms and a Weight Training/Aerobics Room. The Locker Room areas will be designed as a hardened area for increased occupant protection during a severe wind event.

Structural design will generally be in accordance with the International Building Code 2012 Edition as adopted and amended by the City of Pittsburg, Kansas. Structural design of the hardened area will generally be in accordance with ICC 500-2008 ICC/NSSA “Standard for the Design and Construction of Storm Shelters”.

II. Structural Systems Description

A. Structural Framing Systems: The roof framing will typically be 1½” x 20 gage wide rib (Type B) painted metal roof deck supported by open-web steel joists and structural steel beams spanning between structural steel beams and columns. A 3” x 20 gage acoustic deck (Type NA) supported by long-span (DLH) steel joists will be provided at the Gymnasium. Precast concrete double tees and load-bearing precast concrete walls will be utilized at the hardened areas. The hardened area will be separated from the adjacent structure by a building expansion joint.

The exterior walls of the hardened area feature 8-foot-tall parapets to help screen the rooftop mechanical units. These higher parapets will require the precast wall panels to be thicker than would otherwise be necessary.

B. Foundation Systems: A geotechnical investigation has been performed at this site and geotechnical recommendations are provided in the report referenced below. Foundations will consist of isolated and continuous shallow foundations bearing on suitable native soil materials or on engineered fill prepared as recommended by the project geotechnical engineer.

ELECTRICAL I. Codes and Standards

A. The following codes are applicable to this project:

1. International Building Code (IBC) – 2012 – with Local Amendments2. International Fire Code (IFC) – 20123. International Energy Conservation Code (IECC) – 2012 4. International Mechanical Code (IMC) – 20125. NFPA 70 National Electrical Code (NEC) – 2011 6. NFPA 101 Life Safety Code – Latest Adopted Edition

B. Publications from the following standards organizations will be used as design guidelines for the project:

1. NFPA 72 National Fire Alarm and Signal Code2. Illuminating Engineering Society of North America (IES)3. Building Industry Consulting Services International (BICSI)4. Americans with Disabilities Act (ADA)5. National Electrical Manufacturer’s Association (NEMA)6. Telecommunications Industry Association (TIA)

C. The project will be designed to conform to the Americans with Disabilities Act and Architectural Guidelines (ADAAG).

II. Electrical Distribution

A. The existing main electric service at the Middle School currently provides capacity for 2000 amperes at 480Y/277 volts. However, bussing inside the main switchboard is rated for 3000 amps, and the 2000-amp trip sensor in the main circuit breaker can be readily upgraded to 3000 amps. Furthermore, this switchboard is readily expandable with clearance available in the main electrical room to include an additional distribution section.

1. The electric utility’s service transformer appears to be quite adequate to accommodate the anticipated electrical loads in the new addition—based upon historical demand data provided by the utility company. The present peak demand is approximately 600 kW (750 kVA).

2. The spare capacity available from the existing main switchboard appears to be more than sufficient to serve the new addition.

3. Additional parallel sets of service entrance conductors will be pulled from the utility transformer to increase the current-carrying capacity of the service entrance feeder.
