Sun Microsystems Campus

Project Overview

Pie was engineer-of-record for deep foundation stabilization / under-pinning of the foundations, re-grading and drainage design between the buildings, and modifications to the fire separation walls. The Sun Microsystems campus is a 563,000 sf class A office consisting of four buildings on a 72 acre site with offices, conference & training rooms, clean room facility, central plant, cafeteria, and fitness center.

After contending with significant structural and civil engineering issues resulting in foundation movement in a below-grade vault and elevator core that translated into problems for the superstructure above, Sun Microsystems retained Pie to assist with both the forensic engineering condition assessment as well as becoming the designer-of-record and providing construction quality assurance/administration for the rehabilitation. The building movement resulted in negative impacts to the stability of the superstructure, and compromised fire separation walls that extended the full height of the building (crawlspace to roof).
