Edmund Central School

Building Renovation & Addition | Roscoe, SD

West Plains Engineering provided mechanical and electrical design for an addition and renovation to the Edmunds Central School in Roscoe, SD.

The addition involved a new building entry, offices, commons area, kitchen, classrooms, gymnasium, and new laboratory totaling approximately 26,660 square feet of new construction, as well as 21,970 square feet of existing building renovation. The renovation includes existing classrooms, laboratory, music, gymnasium, and other support spaces. The project also involves a new parking lot, playground and other site improvements.

The mechanical system uses VAV rooftop units with chilled water/heating water coils, and with heat recovery units for the building. VAV boxes were used in conjunction with the rooftop for individual control of each classroom. The boiler plant included two high-efficiency hot water boilers with a variable primary pumping system. The chilled water plant included an air-cooled chiller system with primary secondary pumping system. Perimeter radiation was used to handle the exterior envelope loads. A DDC direct digital temperature controls system was used to provide the proper control for the temperature in the building.

The domestic water system was provided with a water softener, and the domestic water heating system consisted of two high-efficiency water heaters. The plumbing fixtures for the project include sensor-activated flushing water closets and urinals, electric water coolers with sensor operated bottle fillers.

The building was protected with a wet fire protection sprinkler system designed to the latest NFPA requirements. A new fire sprinkler service was brought to the building and extended inside.

The electrical system included new LED lighting and the relocation of some fluorescent lighting. The gymnasium was designed with a dimming system for multiple uses. The electrical service was changed from a 120/240V, 800A/ Single Phase system to a new 277/480V, 3 Phase, 4 Wire system utilizing “Integrated Power Centers” for 277/480V and 120/208V distribution and branch circuits. The chiller was served with a separate feeder, not through the building service main switch. A new fire alarm system and data closet were designed in the project with relocation and reconnection of the existing to the school. Camera rough-ins were provided for the owner’s camera system installation. A new door access and intercom system was designed for integrated access for public and staff entrance.
