Trade Package - Airport Substation Transformer Upgrade Project - TP 09 - Deep Foundation

The San Francisco Airport Substation Transformer Upgrade Project requires a design‑builder to install deep foundations beneath three new 55‑MVA transformers and associated switchgear. The work is confined to the West of Bayshore (WOB) property, which includes environmentally sensitive habitat for the endangered San Francisco garter snake, so construction must be phased to avoid operational disruption and ecological impact. The trade package (TP‑09) covers earthwork and trenching for below‑grade foundations, with an estimated cost of $2.5 million. Bids are due by 3:00 PM on October 14, 2026. • Scope: below‑grade deep foundations for transformer pad and switchgear support. • Location: West of Bayshore property, San Francisco International Airport, CA. • Environmental constraints: compliance with the San Francisco Garter Snake Recovery Action Plan. • Budget: $2.5 M (Cost‑Maximum‑Design). • Submission deadline: 3:00 PM, 14 Oct 2026 (RFQ). • Contact: Leila Lilazi ([email protected]).
