Service coverage

Focused where local pricing matters.

Primary coverage is Southern California and the Central Coast. Arizona and Nevada can be supported selectively when the GC already has local trade relationships.

Arizona & Nevada

Selective support before formal expansion. Best fit: existing GC clients with in-state subcontractors who need estimating discipline, formatting, scope review, and SOV support.

  • Commercial TIs and renovations
  • Restaurant and retail rollouts
  • GC-provided local subcontractor coverage

How it works

Simple intake. Clear conflict check. Then bid production.

  1. Send the intake.GC name, project owner/name, address or APN, bid date, project type, and scope summary.
  2. Conflict check.Sierra checks the private internal register by project address, owner, and scope.
  3. Clear or conflicted.If clear, you receive a scoped fee proposal. If conflicted, the project is declined with no details shared.
  4. Bid preparation.Internal bid, SOV, bid forms, assumptions, alternates, exclusions, and final package are prepared per agreed deliverables.

Conflict-free

One GC per project. No double bidding the same project for competing general contractors.

Transparent

Assumptions are documented. Pricing logic is visible. No black-box estimating.

Confidential

Project details, GC identity, and bid contents stay inside the engagement. NDAs available on request.
