PROJECT NARRATIVE

THE PROCESS

PBK worked with the Corona-Norco USD team to provide a design of the new Gym and Performing Arts Center for Corona Fundamental Intermediate school. PBK worked with the district and Principal in developing a program summary, the proposed design and associated costs. The District has communicated the need for a space that can house a gym, (2) locker rooms, (2) offices, gender neutral RR’s, (2) multi-occupant RR’s, a stage as well as support spaces. Currently the existing Multi-Purpose Building consists of Locker rooms, support spaces, an MPR and supports 552 students. The Principal indicated that the new building needs to match aesthetically to the adjacent classroom / administration building and that the public entry must be on the S. Belle Ave. as this is where student pick-up and drop-off occurs. The New Gym and Performing Art’s center is designed to relocate the program of the existing multi-purpose building to the new facility, account for additional spatial needs, and is designed to support 800 students. By working with the district PBK established a set of programmatic needs and developed various design options to determine the best design to proceed with.

The proposed design, project program, basis of design, project schedule and cost estimate are outlined in detail later in this document.
