BACKGROUND

Simpson Gumpertz & Heger, Inc., was selected as part of a competitive, qualifications-based solicitation process to design Support Buildings Seismic Improvements at Plant No. 1, Project No. P1-137. At the time of the solicitation, the Orange County Sanitation District (OC San) documented its intent to award a subsequent agreement to the design consultant for continuation of engineering services during construction.

OC San completed the Seismic Evaluation of Structures at Plant Nos. 1 and 2, Project No. PS15-06, as part of the FY 2017-2018 General Manager's Workplan to enhance infrastructure reliability. The study initiated a long-term seismic upgrade program aligned with OC San's Strategic Plan and Capital Improvement Program. It identified high-priority deficiencies in staff-occupied and critical structures at Plant No. 1 that could limit safety and immediate occupancy following a seismic event.

This project includes rehabilitation of the following buildings: Auto Shop; Control Center; Buildings A, B, 3, 5, and 6; Warehouse; and the 12-kV Service Center.
