How a project runs

Four steps, no surprises

  1. STEP 1

    Scope the work

    Call (949) 678-7913 or send the plans. We tell you which investigation, tests and inspections the jurisdiction will actually require.

  2. STEP 2

    Proposal

    You get an itemized quote — usually same business day — with unit rates so you can check it against the bid.

  3. STEP 3

    Field & lab

    Technicians and inspectors mobilize on schedule. Cross-certified staff cover multiple scopes per trip where the code allows.

  4. STEP 4

    Reports that pass

    Signed, sealed documentation written for the plan checker and usable by the contractor, delivered on the timeline we committed to.
