Description

The Twin Rivers Unified School District is soliciting sealed electronic bids for the construction of a building pad, utility connections, demolition, new fencing, irrigation, and related site work to support a leased portable Transitional‑Kindergarten classroom at Sierra View Elementary School. The scope excludes the portable structure itself, which will be supplied under a separate contract. The project requires coordination with a modular‑unit contractor, compliance with DSA safety plans, prevailing‑wage rules, and a mandatory pre‑bid conference. • Site preparation: grading, building pad, tree removal, demolition of existing fences/gates. • Utility installation: new electrical, low‑voltage, and plumbing services to the portable unit. • New site improvements: black‑vinyl fencing, gates, irrigation, path‑of‑travel upgrades, and landscaping. • Coordination & compliance: mandatory pre‑bid meeting, DSA safety plan, performance/bond requirements, and prevailing‑wage compliance.

Budget estimate

$200,000 – $300,000

The Engineer’s estimate for the whole project is $500,000, but the bid package threshold is $220,000 and the district’s stated budget for the site‑work portion is roughly $220,000 plus a 10 % contingency (≈ $242,000). Considering typical contractor margins (10‑15 %) and the possibility of change orders, the expected contract award to the winning bidder will likely fall between $200k and $300k.
