Construction estimating services in Irvine, CA

The figures come from the U.S. Census Bureau's Building Permits Survey, which counts new privately-owned residential units permitted by the city itself. For 2025, Irvine issued 1,746 units, down 53 percent from 3,730 in 2024. That total splits into 368 single-family and 1,378 multifamily units, with multifamily at 79 percent of the mix. It is residential only; it does not include commercial or industrial permits.

Yes. With 1,378 of 1,746 permitted units in multifamily, most takeoffs we run here involve repeated floor plates, podium transitions, and Type III or Type V construction over concrete. Repetition means your per-unit quantities stabilize quickly, but the first level and the roof still carry one-off detailing. We separate the typical floor from the base and roof so your buyout reflects where the real cost sits.

Much of Irvine is underlain by marine terrace deposits and older alluvial fan soils, and expansive clay is common in some areas. That often means over-excavation below footings, import fill, and sometimes post-tensioned slabs. We read the geotechnical report before we price foundations, because the recommended bearing depth and the presence of undocumented fill change footing quantities directly. Confirm site-specific recommendations with the geotechnical engineer and the city building department.

We cover the full set, from Division 02 sitework and Division 03 concrete through Divisions 22, 23, and 26 for MEP and Division 31 earthwork. Deliverables come in Excel and PDF organized by CSI MasterFormat division, with marked-up plan sets so you can trace each quantity back to the sheet. If you only need one trade, we can scope to that division alone.

Most projects return in 24 to 48 hours, and rush turnaround is available when a bid date is close. Timing depends on sheet count, the number of disciplines, and whether we are working from a full permit set or a design development set. Send the architectural, structural, and MEP sheets together when you can; pricing a partial set means we have to flag assumptions instead of measuring them.

We use ZIP-code-adjusted material and labor pricing, so Irvine quantities carry Orange County rates rather than a statewide average. That matters on trades where labor is a large share of the installed cost, such as framing, drywall, and MEP rough-in. We work from RSMeans data and adjust for the specific scope, story height, and access conditions described in your plans.

Send the plan set, the specifications, the geotechnical report if you have it, and the bid form or scope sheet you are pricing against. If there is a schedule or a phasing plan, include it, because phased work changes general conditions and crane or hoist time. Tell us the bid date and whether you want a single trade or the full package.

Yes. We cover Santa Ana, Riverside, Stockton, Chula Vista, Fremont, and San Bernardino, along with the rest of California. Rates and code editions shift between jurisdictions, so we adjust pricing by ZIP code and flag anything jurisdiction-specific for you to confirm locally. If your project spans two cities, we can price each separately so you can compare.

Energy code compliance in California affects envelope, glazing, lighting, and HVAC selection, and it can add equipment and controls that do not appear on the architectural drawings. We read the Title 24 documentation when it is available and carry the specified assemblies, insulation values, and equipment efficiencies into the takeoff. Where documentation is not yet issued, we flag the affected line items as allowances so you know what is still open.

Every quantity in the spreadsheet is tied to a color-coded markup on the plan sheet, so you can see exactly where a number came from and check it against your own read. That is useful when a subcontractor challenges a quantity or when a plan revision changes one area. Markups are delivered as PDF alongside the Excel workbook.
