On a food plant job, the real cost of a curb isn't the curb. It's how long that area stays tied up. A coated concrete curb typically goes through forming, pouring, curing, grinding, prep, coating and another cure before the area can be handed to the next trade. A prefabricated stainless curb, filled with concrete on site, takes several of those steps out. On a typical 100 lin. ft. install, areas can be released 15–20% sooner. That time shows up downstream: following trades start earlier, the schedule tightens and time-based costs come down. Results vary by site.
Why this matters
Most curb comparisons stop at the price per foot. For a general contractor, the bigger number is usually what happens around the curb: how long the area is held, who is waiting on it, and what every extra day on site costs. This article looks at stainless curbs purely from that cost and schedule angle.
Where the time goes with a coated curb
On most projects, a coated concrete curb involves a sequence like this:
- Form and pour the curb
- Wait for the concrete to cure
- Grind and prep the surface
- Prime and apply the urethane cement or coating system
- Wait for the coating to cure before traffic and wash-down
Each step is short on its own, but each one holds the area. Until the curb is finished and cured, the trades that follow often can't fully start.
Faster release: what it means downstream
When curb areas are released sooner, the benefit carries through the rest of the job:
- Following trades start earlier. Equipment setters, process piping, electrical and controls crews can move into the area sooner instead of waiting on cure windows.
- Less trade stacking. Earlier starts mean fewer crews squeezed into the same space late in the job, which usually means better productivity and less need for premium-time shifts.
- Fewer return trips. With no coating on the curb face, there's no flooring crew coming back just to touch up chipped curb edges before turnover.
- Earlier turnover. Where curbs sit on or near the critical path, time saved in those areas can carry through to substantial completion.
Where the savings show up
- Time-based general conditions. Site supervision, trailers, equipment rental and temporary services are paid by the day or week. Fewer days held means less spend.
- Overtime and acceleration. A schedule with more room needs fewer weekend shifts and less acceleration to hit milestones.
- Liquidated damages exposure. On tight contracts, days recovered early in the job are cheaper than days recovered at the end.
- A stronger bid.
How much this is worth depends on the project. Where curbs are on the critical path, the schedule savings can be significant. Where they aren't, most of the value comes from fewer return trips and less coordination.
Compare the full cost, not just the unit price
Stainless costs more per foot than a coated concrete curb. A fair comparison looks at the whole picture:
- Curb material and installation
- Forming, grinding, prep and coating labour
- Cure and wait time before the area can be released
- Return trips and touch-ups before turnover
- Days the area is unavailable to following trades
- Your general conditions cost per day
Planning to protect the savings
- Release early. Made-to-order stainless needs lead time, so settle the curb layout and release shop drawings early.
- Field-verify. Confirm dimensions on site before fabrication to avoid rework.
- Coordinate the floor transition. Agree on the curb-to-floor detail with the flooring contractor up front.
- Protect installed curbs. Stainless can dent under heavy impact, so protect curbs in high-traffic construction zones until turnover.
How we approached it with HygieniCurb™
We designed HygieniCurb™ for food and beverage facilities with schedule in mind:
- Stainless steel face, concrete core. Mounts to the wall and is filled with concrete on site.
- Fully welded and sealed to help keep moisture and contaminants out.
- 304L or 316L stainless, in 14 or 16 gauge.
- Simpler install. No forming, grinding, priming or coating on the curb. On a typical 100 lin. ft. install, areas can be released 15–20% sooner. Results vary by site.
- Made to order for your layout.
Questions to ask on your next food plant bid
- Are curbs on or near the critical path in any area?
- Which trades are waiting on curb areas to be released?
- What do your general conditions cost per day on this job?
- How many return trips did curbs need on your last food project?
- Would a stainless alternate strengthen your bid with the owner?
Disclaimer: Performance, installation time and cost savings depend on site conditions, project schedule, substrate, installation practices and the contractor performing the work. Install time figures are based on a typical 100 lin. ft. install, and results will vary by project.
