Start with the failure or objective
What should the first site visit settle?
Retaining wall excavation must accommodate footing geometry, reinforcement, drainage aggregate, pipe, waterproofing access and safe slopes or shoring. The temporary cut can be more demanding than the finished wall footprint.
For a retaining wall excavation project in Anaheim, the useful outcome of the first visit is a defined repair or construction boundary—not just a verbal unit price. Access, neighboring improvements, site operations, drainage and the handoff to other trades should be visible in the written scope.
Ask the estimator to label assumptions and exclusions. A number that omits preparation, disposal, permits, testing, traffic phasing or restoration is not directly comparable to a complete proposal.
