How to Price a Commercial Parking Lot Paving Job | Reddit & LinkedIn

A commercial paving bid is driven by three things: the area, the asphalt depth, and the condition of the base underneath. A clean overlay on a solid base is a fraction of the cost of a full-depth reconstruction that requires milling, dig-out, and new aggregate. The asphalt is a commodity; the earthwork is where the price moves.

Walk the lot and zone it. Mark the sections that need only an overlay and the sections that are failing and need full-depth repair. Pricing the whole lot at one rate either overprices the good areas or underprices the bad ones, and both lose you the job or the margin.

The subgrade decides whether the asphalt lasts or fails in two winters. Check for standing water, alligator cracking, and soft spots that signal a failed base. A lot that ponds water needs drainage correction or the new asphalt fails early, and that correction is a real line item, not an optional extra.

Bid the base honestly. If the subgrade is questionable, carry a dig-out and aggregate allowance and state that soft areas found during milling are priced as change orders. That protects you from a base that looks fine until the paver is on site.

• Overlay: solid base, mill the edges, pave a new lift.
• Full depth: remove asphalt and base, rebuild the aggregate.
• Drainage: correct ponding before paving or the lot fails early.
• Dig-out: price failed subgrade areas separately.

Convert the paving area and the lift depth to tons using the mix density, then add a waste factor. A thicker lift or a heavier commercial mix changes the tonnage and the price, so match the spec to the traffic load the lot carries.

Price labor and equipment by the day: the paver, the rollers, the crew, and the trucking that hauls hot mix from the plant. Milling, when required, is its own day-rate line. A commercial paving crew is an expensive daily unit, so estimating days accurately matters more than shaving the per-ton price.

Beyond asphalt and earthwork, a commercial lot needs striping, ADA-compliant stalls and access aisles, wheel stops, and signage. These are code items on a commercial lot, not extras, so price them on their own lines. Add any grading permit or right-of-way permit the jurisdiction requires.

Sequence and access matter too. If the client needs the lot open in phases so the business keeps running, price the phasing, because paving half a lot at a time costs more than paving it all at once.

Carry a written contingency for soft subgrade and unexpected dig-out, and state that conditions found during milling are change orders priced before the extra work starts. That single clause keeps a hidden base failure from turning a profitable job into a loss.

Structure the bid as milestone draws: a deposit at mobilization, a draw at base completion, and a final payment at striping and acceptance. ContractShield invoices each draw, takes card or ACH through Stripe, and Collections chases any late payment with a sequence you approve with one tap.
