BACKGROUND:
This project provides for the demolition of the Old Juvenile Hall facility located at 202 Glacier Drive, Martinez.
Contra Costa County Risk Management has restricted access to Old Juvenile Hall because it contains hazardous building materials and other contaminants. The building has become a health and safety hazard. Additionally, this building is outdated and no longer serves the needs of the Probation department and is inadequate to address current advances in rehabilitative programming, trauma-informed care, and behavioral science that is required to meet the needs of today’s youth and the staff tasked with their care.
Old Juvenile Hall is an approximately 54,694 square-foot, two-story building constructed in 1950 and expanded in 1975. Demolition will commence with the abatement and disposal of hazardous materials, followed by the complete demolition of the building and its underground utilities. The project scope includes installing temporary and permanent security fencing, backfilling and grading the site, hydroseeding, and installing new irrigation lines. A retaining wall will be built to shore up the play yard areas, and a new emergency generator will be installed.
On October 7, 2025, the Board of Supervisors authorized the Public Works Director to solicit bids for the Project. Public Works obtained permit approval for the plans, and the Board determined that the project is exempt from CEQA.
On December 3, 2025, Public Works opened bids. Ten (10) contractors submitted bids against a construction cost estimate of $6,217,000. The bid results are as follows:

Public Works Department staff have thoroughly reviewed the bids. Staff determined that the low bid submitted by Penkor General Contractors, Inc. is responsive and that Penkor General Contractors, Inc. has documented an adequate Good Faith Effort (GFE) to comply with the requirements of the County’s Outreach Program.
Therefore, staff recommends that the construction contract for this Project be awarded to Penkor General Contractors, Inc., the lowest responsive and responsible bidder, in the amount of $4,500,000.
CONSEQUENCE OF NEGATIVE ACTION:
Without the Board of Supervisors’ approval, the Old Juvenile Hall facility will remain an ongoing hazard, risk, and attractive nuisance. Additionally, the facility’s presence will prevent potential redevelopment of the area for beneficial use.
