If you run civil for a production builder in the Lowcountry, you already know the margin math. A subdivision sitework contractor in SC either hits the per-lot number and the phase release schedule, or the pro forma slips and the VP of Construction starts asking questions. This playbook lays out how JSW Construction prices, phases, and self-performs subdivision civil scopes for builders like Lennar, DR Horton, Pulte/Centex, Mungo, Crescent Homes, Hunter Quinn, Beach Company, Daniel Corp, and Brookfield across active Berkeley, Charleston, and Dorchester County communities. We wrote this for the civil manager scoping the next phase at Nexton, the super running pad prep at Cane Bay Plantation, and the estimator pulling quantities for Carnes Crossroads, The Ponds, Summers Corner, Del Webb Nexton, Del Webb Cane Bay, Myers Landing in Goose Creek, or Point Hope at Cainhoy.
If you want to skip the reading and send a takeoff, request per-lot pricing and we will turn it around against your quantity schedule. Otherwise, here is how we think about the work.
How We Scope a Subdivision Civil Package
Every subdivision civil package we take on starts with the same triage. We pull the approved civil drawings from the engineer of record, the geotech report, the SCDHEC stormwater permit, and the recorded plat from the surveyor. From there we build a per-lot quantity template: cut and fill by lot, wet utility laterals, dry utility conduit stubs, flatwork square footage, and the driveway apron count. That template is what drives both our per-lot price and our phase mobilization plan.
Scope on a typical Lowcountry subdivision lot includes site prep and clearing, mass excavation to subgrade, rough grade, wet utilities (water service, storm laterals, sanitary sewer), dry utility trench for fiber conduit and power, flatwork (sidewalks and driveway aprons), fine grade to finish pad, and builder pad prep. We self-perform all of it with our own fleet, which is the reason we can hold a per-lot number across a 200-lot phase without relying on a chain of subs to keep their pricing.
Per-Lot vs Lump-Sum: Which Pricing Model Fits Your Project
Production builders almost always want per-lot pricing. It matches the way your accounting system draws against each closing and it lets the super release lots in small batches without renegotiating the sitework contract. Land developers selling finished lots to multiple builders typically prefer lump-sum per phase, because the scope is defined by a plat and a release date rather than a house plan. Here is how we frame the three pricing models we quote most often.
Per-lot pricing works best when the lot mix is consistent, the builder is taking down lots in a predictable cadence, and the civil drawings are fully permitted. We quote a single number per lot type (50 ft single-family, 70 ft single-family, townhome, duplex, large-lot), and that number covers everything from clearing the lot to handing a finish pad to the framing super. If the mix shifts, we apply the matching lot-type price to the new release.
Lump-sum per phase fits horizontal land development where the client is the developer, not a builder. You are paying for a phase of infrastructure (mass grading, wet utility mains, storm ponds, road section to binder) and the deliverable is finished lots ready for vertical. We quote lump sum against the civil plans with clear allowances for unsuitable soils and dewatering.
Unit-price with quantity schedules is the middle path. We quote per linear foot of 8 in PVC sanitary, per cubic yard of unsuitable export, per square yard of sidewalk, per each for yard inlets. This protects both sides when quantities are uncertain, which is common on Lowcountry jobs where the geotech surprises get real below the phosphate layer.
Typical Per-Lot Cost Ranges by Scope
The table below shows the ranges we are currently pricing across active Berkeley, Charleston, and Dorchester subdivisions. These assume a fully permitted civil package, reasonable soils (Coastal Plain fill, not heavy organics), and a phase of at least 40 lots so mobilization is spread. They cover lot-scope only: clearing, rough grade, wet and dry utility stubs from the ROW, driveway apron, sidewalk across the frontage, and finish pad to slab subgrade.
| Lot Type | Typical Frontage | Per-Lot Range (Lot Scope) | Notes |
|---|---|---|---|
| Single-family 50 ft | 50 ft | $8,500 to $12,500 | Standard slab product, minimal cut/fill |
| Single-family 70 ft | 70 ft | $11,500 to $16,000 | Longer apron, more sidewalk, larger pad |
| Townhome lot | 20 to 24 ft | $5,500 to $8,000 | Shared wall, shared utilities, tighter pad |
| Duplex lot | 60 to 80 ft | $10,000 to $14,500 | Two utility sets, single pad |
| Large-lot > 1/4 acre | 90 ft plus | $15,000 to $24,000 | Septic prep possible, longer driveways |
These are honest ranges, not teaser numbers. If your civil drawings push us outside them (heavy unsuitables, deep sanitary, long utility runs to the main), we will tell you at bid and show the math. Send drawings to request per-lot pricing calibrated to your project.
Phasing Vocabulary: What We Price Against
A phase release on a 400-lot community like Del Webb Nexton or Cane Bay Plantation is not one job. It is a series of mobilizations tied to your lot release schedule and your house starts forecast. We price against three pad states and two mobilization tiers.
Warehouse pad is rough graded, compacted to spec, and staged for material storage or a model row. It carries no fine grade. Rough pad is cut to plan grade plus or minus 0.2 ft, ready for utility service stubs and fine grade. Finish pad is the one the framing crew wants: fine graded to slab subgrade, compacted per geotech, with the apron and sidewalk forms ready. We quote each state separately so you can release lots in the order your starts calendar actually runs.
Phase 1 mobilization absorbs the cost of moving the full fleet (skid steers, mini-ex, 8k, 60k, and 80k excavators, wheel loader, rollers, and water truck) on site and running crew. Phase 2 and later mobilizations are lighter because the main infrastructure is already in and we are running lot-scope work against the existing plan.
What Our Crews Self-Perform on a Typical Subdivision Lot
Self-perform percentage matters to the civil manager because every sub you add is a schedule risk and a coordination tax. On a standard Lowcountry subdivision lot, JSW crews directly perform clearing and grubbing with the 60k excavator and loader, mass excavation and rough grade with the 80k and dozer pulling GPS, wet utility laterals (3/4 in water, 4 in sanitary, 12 in to 18 in storm) with the 8k and mini-ex, dry utility trench and conduit placement for fiber and power, flatwork forming and placing for sidewalks and driveway aprons, fine grade with the skid steer and laser, and final pad prep with compaction testing hand-off to the geotech.
What we coordinate rather than self-perform: paving binder and surface, streetlight poles, final power energization, and landscape. We run the schedule with your builder super, the civil engineer of record, the geotech field rep, the surveyor for pad elevations and lot pins, and the county inspector for utility and BMP sign-offs. That coordination is built into our per-lot number; it is not an extra line item.
Expert Insight from Nikki Walker
"The builders who get the best numbers from us are the ones who share their starts forecast 90 days out and let us match our mobilizations to their release cadence," says Nikki Walker, who leads commercial estimating at JSW. "A per-lot price looks flat on paper, but underneath it we are solving for how many lots we can prep in one pass of the excavator and one pour cycle of the flatwork crew. When a civil manager at a community like Carnes Crossroads or Summers Corner tells us the actual release schedule instead of the aspirational one, we can hold pricing through the full phase. When we are guessing, we have to carry risk in the number, and that costs the builder. Transparency on the schedule is worth real dollars per lot."
How to Get a Per-Lot Number Back Fast
We turn takeoffs around inside five business days when we have: approved civil drawings, the geotech report, the plat with lot numbers and types, a release schedule or starts forecast, and any special conditions (HOA flatwork color, decorative aprons, tree save requirements). If you are early in feasibility and only have a concept plan, we will quote a budget range based on comparable active jobs at Point Hope, Myers Landing, The Ponds, or Nexton and refine once the civil drawings are stamped.
