Description

This Caltrans project calls for extensive heavy‑construction work in Mendocino County, CA, including bulk earthmoving, the construction of soldier‑pile retaining walls, and the placement of a new roadway segment. The contract is estimated at $14.5 million and requires a Class A license or a combination of specific Class C licenses (C‑12, C‑8, C‑61, D‑09). A mandatory pre‑bid conference is scheduled online, and bidders have roughly a seven‑week window to review documents and prepare their proposals. The work schedule spans 230 working days from award to completion, demanding mobilization of equipment, labor, and material logistics in a relatively remote county setting. • Scope: earthwork, soldier‑pile wall construction, roadway installation. • Estimated value: $14.5 M; 230‑day construction schedule. • Licensing: Class A or specific Class C combinations required; compliance with Title VI nondiscrimination.

Budget estimate

$700,000 – $1,500,000

The estimated contract value is $14.5 M. Assuming a typical subcontractor profit margin of 5‑10 % for heavy civil work, the net earnings for the prime contractor could range from roughly $725,000 to $1.45 M. Factors influencing the final budget include the scope of work taken on (full scope versus partial), prevailing labor rates in Mendocino County, equipment mobilization costs, and the complexity of the soldier‑pile wall construction.
