Korsmo Construction built this new state-of-the art 134,000-square-foot middle school to house 1,000 students on an existing 22-acre occupied site for the Clover Park School District. The Korsmo team worked closely with the District and architect to complete the design phase to align within the District’s tight budget and schedule. The project included football and baseball fields, track, and athletic courts.
The Korsmo team offered cost and time-saving solutions, including phasing of an early water line during the existing school’s summer break to avoid impact to students and staff; critical path method schedule phasing to get a head start on construction of the new field so it could be used in the fall; and the use of cement-treated base over the entire building footprint to “armor” subgrade and limit unsuitable soils risk. This option saved about $750,000 per vertical foot of potential excavation and fill. The team also recommended additional test pits, which revealed an increased swath of existing fill in the middle of the new building footprint. Excellent bid coverage resulted in the project being well under the 90 percent construction document estimate.
