A realistic Charlotte-area commercial concrete project — dumpster pad replacement, parking-lot section repair, ADA curb-ramp retrofit — runs bid to punch walk in 21 days. Not seven, not five. Twenty-one, and here is where the days actually go.
Days 1–3: Bid
Property manager sends a walk-through request or a plan set. Estimator walks the site or reads the drawings within 48 hours, priced written bid delivered within 72 hours. That is the industry-standard turnaround from a commercial concrete crew that is actually paying attention.
The bid should include: line-item quantities, mix design (PSI, air-entrainment, admixtures), joint plan, mobilization, permit costs, and a realistic pour window. If a bid comes back as a single lump-sum with no line items, the bidder has not read the drawings.
Days 4–5: Bid review and award
Property manager reviews the bid, compares against comparable bids, and awards. This is usually two business days if there is a single decision-maker; longer if there is a portfolio owner or regional review. The award triggers the paperwork phase, not the pour phase.
Days 6–8: COI, W-9, and vendor packet
Certificate of Insurance issued naming the property management company and property owner as additional insureds. W-9 delivered. Vendor packet (contractor license, contact information, references) completed. All of this is same-day work if the contractor has done it before, but AP teams typically take 48 to 72 hours to process the packet before releasing the project to schedule.
Days 9–14: Permit and mobilization
- Municipal permit lead time — Charlotte typically clears right-of-way permits in 5 to 10 business days. Union County, Cabarrus, and Gaston Counties run 7 to 14. Weekend or after-hours work requires additional notification.
- Waste hauler coordination — if the project affects a dumpster pad, the waste hauler needs 3 to 5 business days notice to move service or accept a temporary bin.
- Tenant notification window — 7 business days is the standard notice property managers should give retail or apartment tenants for concrete work affecting parking or trash service.
Days 15–18: Pour and cure
Subgrade prep on day one of mobilization, pour on day two, cure protection through day three. Standard 4000 PSI mix reaches walk-ready strength in 24 hours and full drive-ready strength in 5 to 7 days. For dumpster pads, we typically pour on a Saturday and return the pad to service on Monday using fast-cure mixes.
Days 19–21: Punch walk and close-out
Property manager walks the site with the contractor foreman, punch list documented, any remaining items completed within 48 hours. Final invoice delivered. Warranty documentation on file. Project closed.
Twenty-one days is the honest calendar. Anyone quoting a five-day turnaround on a public commercial project is either skipping paperwork you will pay for later or has not actually run the permit clock.
