About this file
This is a final construction plan document for the County of San Mateo Public Works Department for the Lerida Court and Gabarda Way Retaining Walls Improvement Project located in Ladera, California. The project encompasses approximately 320 feet of retaining wall improvements along County Road No. 222, involving demolition of existing deteriorating soldier pile and wood lagging walls and construction of new shotcrete-faced retaining walls supported by cast-in-drilled-hole concrete piles, steel walers, and dual rows of ground anchors. The scope includes drainage system improvements consisting of concrete swales, gutters, and new storm drain infrastructure with drop inlets; removal and replacement of asphalt concrete pavement and base material; rock slope protection; site restoration with hydroseed and fiber rolls; tree removal; and coordination with existing water, electrical, sanitary sewer, and storm drain utility lines. Sealed bids are due by 2:30 p.m. on Thursday, March 19, 2026, submitted to the County Executive's Office, 500 County Center, 5th Floor, Redwood City, California 94063. The anticipated contract award date is April 7, 2026, with contractors required to begin work within ten calendar days of receiving the Notice to Proceed and complete the project within 80 working days.
The Engineer's estimate for the project is $3,060,000. Contractors must possess either a Class A License or applicable Class C licenses and be registered with the California Department of Industrial Relations. All bidders must comply with prevailing wage requirements under California Labor Code Section 1770 et seq., with rates available through the Department of Labor Standards Enforcement. Contractors are required to obtain comprehensive general liability insurance of $1,000,000, motor vehicle liability insurance of $1,000,000, and professional liability insurance of $1,000,000, with the County named as additional insured. The project is subject to liquidated damages of $4,800 per calendar day for delays, 100 percent diversion of inert construction materials, and water pollution control measures. Plans and specifications are available for download via the OpenGov website or for purchase at a nonrefundable fee of $40 per set from the Director of Public Works. Bids may not be withdrawn for forty-five days after bid opening, and the County reserves the right to reject any or all bids.
