Sitework takeoff
Clearing, excavation, select fill and drainage for sandy and clay subgrades across Nueces County.
CY · SF · LFWe produce CSI MasterFormat takeoffs and estimates for builders and bidders in Corpus Christi and the Coastal Bend. Send your plan set and get an Excel and PDF estimate in 24–48 hours, with quantities marked up on the drawings.
Corpus Christi pricing turns on four things: wind-uplift and flood-zone requirements on coastal structures, expansive clay and sandy subgrades across Nueces County, refinery and port-driven industrial scopes, and a residential market where 1,220 single-family units were permitted in 2025. Each changes quantities, not just unit prices.
Corpus Christi sits where the Gulf Coast meets the Coastal Bend, and that location shows up in every takeoff. Roof assemblies on the island and near the bayfront carry wind-uplift fastening schedules that add clips, straps and ring-shank nails beyond a typical inland count. Foundations in the clay and sandy soils west of the bay often require over-excavation, select fill and post-tension slab quantities that a generic square-foot number will miss.
The 2025 permit data tells you where the volume is: 1,384 new privately-owned residential units, up 7% from 1,291 in 2024, with 1,220 single-family and 164 multifamily. Permitted value was $375M, an average of $270,700 per unit. Corpus Christi ranks 14th of 25 covered Texas cities by residential units, holding 1.9% of the 72,008-unit state total. If you bid here, your estimate has to reflect coastal assemblies, not a statewide average. Our Texas construction estimating work covers the whole state, and we price material and labor by ZIP code so coastal premiums land in the right line.
For bidders. You need quantities you can defend in a bid review. We mark up the plan set and organize the Excel by CSI division, so your buyout and your bid form match line for line.
For builders. You need a budget that survives a coastal inspection. We count wind-uplift fasteners, slab reinforcement and drainage scope that a square-foot estimate skips, then price it with ZIP-adjusted RSMeans data.
For owners. You need a scope check before you commit. We compare your plans against a full takeoff and flag missing divisions, so change orders do not arrive in the first month of construction.

1,384 new housing units in 2025 (+7.2% vs 2024).
1,220 single-family · 164 multifamily (12%).
Corpus Christi issued 1,384 new privately-owned residential units in 2025, up 7% from 1,291 in 2024. Single-family accounted for 1,220 units; multifamily was 164, or 12% of the total. That mix matters for takeoff work. Single-family plans repeat, so a builder running the same plan on multiple lots gets more value from a reusable quantity model than from one-off counts. Multifamily at 164 units is small but not trivial; those jobs carry common-area MEP, elevator and sitework scope that a house takeoff never touches. Permitted value of $375M works out to an average of $270,700 per unit, which is a useful sanity check when your own budget comes in far above or below it. For the broader state picture, see our Texas construction estimating page.
At 14th of 25 covered Texas cities by residential units, Corpus Christi is a mid-volume market, holding 1.9% of the 72,008 units permitted across those cities. That ranking tells you something practical: you are not competing with the volume of a Dallas–Fort Worth suburb, so bid margins are tighter and quantity errors cost more. Contractors who also work El Paso or Laredo often ask us to keep a consistent format across markets so their crews and suppliers can compare scopes. The industrial side is different from all of them. Refinery, petrochemical and port work around the ship channel brings structural steel, pipe racks, foundations and coatings scope that follows a different estimating rhythm than residential. We handle both from the same marked-up plan set.
We take off the divisions that drive cost in the Coastal Bend, from dirt to finishes, and deliver them in one organized workbook.

Your plan sets repeat across subdivisions in Nueces and San Patricio counties. We build a takeoff once, then reprice per lot as soil, drainage and roof geometry change.
Your 164-unit share of the city's 2025 residential permits sits in low-rise, garden-style and wrap buildings where unit-mix repetition hides real cost differences between types.
You buy one scope and need it measured precisely. We extract your division cleanly from the full set so your bid does not carry the general contractor's contingency.
You need a cost check while drawings are still moving, so scope gaps surface before they become change orders after permit issuance.
You are adding to an existing building or replacing storm-damaged assemblies, and you want an independent quantity check before you sign a contract.
We take off plans from anywhere in the Coastal Bend, and the ZIP code drives the material and labor pricing. If your project sits on the island, along the bay, or inland toward the refineries, the quantities change with the exposure category.
The 2025 permit mix was 1,220 single-family and 164 multifamily units, with $375M in permitted value at an average of $270,700 per unit. That tells you where the drawing volume is, and it is mostly residential with a steady commercial and industrial tail.
Detached homes in Southside, Calallen and Flour Bluff subdivisions, plus custom builds on the island. We count slab reinforcement, roof sheathing and wind-uplift fastening schedules that coastal plan sets carry.
Watch for: Roof clips, straps and ring-shank nail counts
Two- and three-story apartment buildings with surface parking, common in the Southside and near the university. Repetitive unit plans hide differences in corner units, stairs and roof geometry.
Watch for: Unit-mix repetition and corner-unit framing
Piling and stem-wall foundations, breakaway walls and elevated living floors on the island and bayfront. Elevation and flood zone drive foundation depth, not the square footage.
Watch for: Pile depth, elevation certificates and breakaway walls
Strip centers, restaurants, offices and self-storage along South Padre Island Drive and the major arterials. Tenant improvements and shell work often arrive as separate scopes on the same set.
Watch for: Shell versus tenant-improvement scope split
Warehouses, fabrication shops, tank pads and maintenance buildings serving the Port of Corpus Christi and the refineries. Structural steel, pipe racks and equipment pads dominate the quantities.
Watch for: Steel tonnage, anchor bolts and equipment pads
Roof replacement, siding, drywall and structural repair after wind and hail events. Repair scopes are measured from field dimensions and photos rather than a clean architectural set.
Watch for: Field-verified dimensions and matching existing assemblies
Two estimates for the same square footage can land far apart here, because wind exposure, soil, drainage and material haul distance all move the quantities. These are the drivers we price explicitly rather than bury in a square-foot number.
Coastal exposure categories drive roof sheathing nailing, fastener spacing, continuous load path straps and opening protection. Flood zones add elevation, breakaway wall and foundation vent requirements. Code editions adopted locally change over time, so confirm the current edition and any local amendments with the City of Corpus Christi building department before you lock quantities. The cost shows up in fasteners, hardware and inspection time, not in the framing square footage.
IBC · IRC · local building departmentMuch of the inland side of the bay sits on expansive clays that shrink and swell with moisture, while the island and barrier side is sandy and needs deeper support. That combination pushes many projects to post-tension slabs with deepened perimeter beams, or to piling and grade-beam foundations. Over-excavation, select fill and moisture conditioning are real line items here, and they are the first thing a square-foot estimate drops.
post-tension slabs · select fill · piling and grade beamsThe Gulf hurricane season runs June through November, and wind-driven rain on the coast is harder on exterior assemblies than inland rain. Roof underlayment, flashing details, window and door installation and exterior sealants carry more labor and better materials. Schedule compression after a storm also raises labor cost, because every roofer and drywall crew in the Coastal Bend is booked at the same time.
hurricane season · roof underlayment · flashing and sealantsThe local labor pool is split between residential trades and the industrial and refinery maintenance market, which pays differently and pulls crews away from building work. Skilled concrete finishers, roofers and mechanical trades are the tightest. We price labor by ZIP code with RSMeans data and adjust for the trade mix, so a residential framing crew and an industrial pipefitter crew are not carrying the same rate.
RSMeans data · ZIP-adjusted labor · trade mixCorpus Christi is flat and drains slowly, so site plans carry detention, swales, berms and finished-floor elevations that inland cities do not need at the same scale. Pad elevation above the floodplain often means import fill, and import fill is a trucking cost. Lot grading, retaining walls and storm sewer quantities belong in the sitework division, not in a site allowance, or the estimate misses them entirely.
detention · import fill · finished-floor elevationMost building materials come in from San Antonio, Houston or the Rio Grande Valley, so freight is a real line item on steel, masonry and precast. Coastal projects also specify stainless or hot-dip galvanized fasteners, connectors and hardware, which cost more than standard mill finish. Sales tax treatment on materials depends on the contract type and the owner, so confirm it with your accountant rather than assuming.
freight · galvanized and stainless hardware · Texas sales taxCoastal exposure, expansive clay over sandy subgrades, and flat sites change quantities in ways a generic Texas template misses. Here is where each trade's takeoff picks up the difference.
Corpus Christi sits on flat coastal ground with a shallow water table in many areas, so mass grading balances are tight and cut/fill is usually net import rather than export. Take off stripping depth by area, then structural fill by compacted cubic yard, not loose yard. Stormwater scope typically includes trench excavation, bedding stone, HDPE or RCP pipe by linear foot, inlets and headwalls by each, and riprap by ton. Confirm the adopted drainage criteria and any local floodplain requirements with the city engineering department. Our sitework estimating services break these into separate bid items so a subcontractor's quote can be compared line for line.
Wind-rated assemblies change both material and labor. Roof sheathing, roof-to-wall connectors, and continuous load path hardware are separate line items from the framing itself, and they are frequently missed on coastal bids. Take off wall framing by linear foot of wall with plate counts, then convert to board feet; roof framing by square with ridge, hip, and valley lengths. Roofing on the coast usually means a wind-rated shingle or standing seam metal system with underlayment and secondary water barrier, plus fasteners specified by corrosion class. Our roofing estimating services and framing estimating services use the same plan markup so the two scopes reconcile.
Single-family work dominates local permitting, and the unit mix matters for pricing. Take off per-plan quantities for each model, then multiply by the number of repeats, and keep a separate column for site-specific items like driveways, fences, and landscaping. For multi-family, common areas, stairs, and elevator shafts are their own takeoff sections. Residential estimating services and multi-family estimating services both start from the same marked-up plan set, with quantities organized by CSI division. See how we handle this across the state on our Texas construction estimating page.
Expansive clay in the region drives post-tensioned slab or pier-and-beam design, and the takeoff has to follow the geotechnical report rather than a standard detail. Count piers by depth range, beam forming by linear foot, and slab area by square foot with a typical 5–10% waste factor on ready-mix. Watch for vapor barrier, capillary break, and post-tension cable and anchorage items that are easy to leave out. Foundation estimating services cover the excavation, forms, reinforcement and concrete as one package so nothing floats between trades. Add mix design surcharges for sulfate-resistant cement where the soils report calls for it.
Salt air pushes specification toward corrosion-resistant materials: copper or PEX-A with proper support, coated hangers, stainless fasteners, and sometimes PVC-coated conduit outdoors. Those substitutions carry different unit costs than the inland default, so the takeoff must follow the specification section, not habit. Count fixtures by type, pipe by diameter and linear foot, ductwork by pound and square foot, and devices by each. MEP estimating services separate plumbing, mechanical, and electrical so you can bid each package to a different sub. Verify local amendments to the mechanical, plumbing, and electrical codes with the building department before pricing.
Quick check for a single element. For a full drawing set, send the plans and we measure everything, including the items calculators miss.
Typical waste: 3–5% for slabs, 5–10% for footings and walls. Truck count assumes 10 CY loads; confirm load size with your ready-mix supplier.

Dimensions below are illustrative. The method is what matters: area, then thickness, then waste, then conversion to cubic yards.
Assume a 52 ft x 34 ft main slab with a 4 ft x 20 ft front porch and a 6 in. thickened edge beam around the perimeter.
| Step | Calculation | Result |
|---|---|---|
| Main slab area | 52 ft x 34 ft | 1,768 SF |
| Porch area | 4 ft x 20 ft | 80 SF |
| Total area | 1,768 + 80 | 1,848 SF |
| Slab volume at 4 in. | 1,848 SF x 0.333 ft | 615.4 CF |
| Perimeter | 2 x (52 + 34) + porch | 192 LF |
| Beam volume, 12 in. x 6 in. | 192 LF x 1.0 ft x 0.5 ft | 96.0 CF |
| Gross volume | 615.4 + 96.0 | 711.4 CF |
| Waste, 7% | 711.4 x 0.07 | 49.8 CF |
| Priced volume | 711.4 + 49.8 | 761.2 CF |
| Convert to cubic yards | 761.2 / 27 | 28.2 CY |
The order of operations is the part estimators get wrong. Waste is applied after beam and slab volumes are combined, not to the slab only, because the pump, chute loss, and uneven subgrade affect the whole placement. On a coastal slab, add the vapor barrier area (1,848 SF plus laps, typically 10%), the post-tension cable footage if the design is PT, and any sulfate-resistant mix upcharge as separate lines so the concrete supplier's quote can be checked against your quantity.
If the geotechnical report calls for a pier system instead, the slab quantity drops but pier concrete, forming, and excavation appear as new line items. Re-run the takeoff against the foundation sheet before you release the bid. Our concrete estimating services and foundation estimating services both follow this sequence, and the output arrives in Excel and PDF organized by CSI MasterFormat division with the plan set marked up.
Wind-rated assemblies add items that a standard framing takeoff does not carry: roof-to-wall connectors, continuous load path straps, and sometimes closer nail spacing than the default. These are counted by each or by linear foot of wall, not lumped into the framing square footage. The plan's structural sheets and the wind speed map drive the quantities, so we take off from those sheets directly. Confirm the adopted code edition and any local amendments with the building department before you price.
Yes, when the specification calls for it. Expansive clay in the area often triggers sulfate-resistant cement or a lower water-cement ratio, and those carry a mix surcharge that must be a separate line item. We also separate vapor barrier, capillary break, and post-tension cable from the slab concrete itself so each can be bid and compared. If your geotechnical report specifies a pier system, we re-takeoff the foundation from that report rather than the standard detail.
Most projects are returned in 24–48 hours, and rush turnaround is available. The clock starts when we have a complete plan set and the scope notes. Larger multi-family or commercial packages with many sheets may take longer, and we will tell you the schedule before we start. Deliverables are Excel and PDF, organized by CSI MasterFormat division, with the plan set marked up so you can trace every quantity back to the sheet.
The figures come from the U.S. Census Bureau Building Permits Survey for 2025. They count permits issued by the city itself for new privately-owned residential units only, so they exclude commercial, industrial, and renovation work. Corpus Christi issued 1,384 total units in 2025, up from 1,291 in 2024, a 7% increase. Single-family units were 1,220 and multifamily 164, or 12% of the total. Permitted value was $375M, an average of $270,700 per unit.
Yes. Multi-family takeoffs separate each unit type, then multiply by the number of repeats, and keep common areas, stairs, and elevator shafts as their own sections. That structure lets you bid the building package to one subcontractor and the site package to another without overlap. Multifamily was 12% of local residential permits in 2025, so the unit mix varies by project. Send the full set, including civil and landscape, so the sitework scope is priced from the same drawings.
Flat coastal sites usually mean minimal fall and tight cut/fill balance, so drainage is priced as a full system: trench excavation by linear foot, bedding stone by ton, pipe by diameter and linear foot, inlets and headwalls by each, and riprap by ton. We do not price pipe alone, because the excavation and backfill are the labor-heavy part. Confirm the adopted drainage criteria and floodplain requirements with the city engineering department before finalizing quantities.
Yes. We cover the surrounding region and other Texas markets, including El Paso, Arlington, Plano, Laredo, Lubbock, and Fort Worth. Pricing is ZIP-code-adjusted for material and labor, so a takeoff for a project in another market reflects that market's costs rather than a single statewide average. If your project is in a smaller town nearby, send the address and we will confirm the pricing basis before starting.
A complete plan set is the main input: architectural, structural, civil, and MEP sheets, plus any specifications and the geotechnical report if foundations are in scope. If you have a bid date and a scope split you want us to follow, include that. We return Excel and PDF organized by CSI MasterFormat division with the plans marked up. Missing sheets are the most common cause of delay, so send what you have and we will flag the gaps.
Corrosion-resistant materials change both material cost and labor. Stainless fasteners, coated hangers, and PVC-coated conduit take longer to install and are counted by each or by linear foot, not by a generic percentage. We take those quantities from the specification sections and price them as separate line items. If the specification is silent, we note the assumption in the deliverable so you can confirm it with the design team before the bid.
Yes. The takeoff is organized by CSI MasterFormat division, which maps directly to subcontractor scopes: concrete, framing, roofing, MEP, and sitework each get their own section with quantities and units. That structure lets you send one section to each bidder and compare quotes line for line. It also makes scope gaps visible, because an item that appears in no section is easy to spot before the bid goes out.
Send your plan set and we will return a CSI-organized takeoff in Excel and PDF, typically within 24–48 hours.
