construction
The owner hired Massaro as a CM agent with a stipulated sum contract. In this case, Massaro does not hold any other contracts with trades and acts as a representative for the school district for a lump sum amount. The owner also holds a contract with an architect with a lump sum, who in turn hired several engineers and consultants under them. The district also holds individual lump sum contracts with several prime contractors as well, including general, mechanical, plumbing, and electrical contractors.
Electrical
The electrical system is sourced by an incoming 208/120V three phase, 4 wire service transformer. Additional electricity comes from the photovoltaic panels located on the roof of the building. These sources provide power to the demanding mechanical and food service equipment, as well as the lighting.
mechanical
For heating and cooling, this building is equipped with a closed loop water source heat pump. The system provides heat in the winter by passing supply air through a boiler located in the mechanical room, which then passes through an electric heat pump. The system is reversed in the summer, using the refrigerant in the heat pump and a rooftop condensing unit to remove heat from the building. This type of system is simple, reliable, efficient, and flexible, making it ideal for large facilities like this school.
lighting
The lighting is mostly made up of drop-in
direct/indirect LED fixtures, as well as some aesthetically pleasing pendants. Large clerestories and curtain walls also allow for ample day-lighting throughout the building.
structural
Spring Creek Elementary utilizes a foundation made up of cast-in- place concrete footings, piers, and slabs. The foundation walls are made of concrete masonry units, which then continue above ground to make up the walls of the superstructure. For added support, W-shaped steel beams and k-joists are used as necessary throughout the structure. The use of masonry as the skeleton of the building is traditional for schools, due to the durability, low cost, and soundproofing advantages of CMUs.
fire protection
The entire building is classified as light hazard, with the exception of the attic, storage rooms, and mechanical rooms, which are considered ordinary hazard. The structure features a wet pipe sprinkler system with all heads being unconcealed pendants. The piping is made of 1 ½” to 2” PVC.
