Multi-Location Programs
Five hundred sites is one job, done five hundred times the same way
Portfolio-wide mechanical work rarely fails on the technical side. It fails between the sites: dozens of local contractors reading one scope dozens of ways, schedules that slip quietly, change orders nobody can compare, and closeout paperwork that never arrives.
We run the program as one project. Sites are surveyed and sorted into tiers by what each needs. The scope is written once per tier and proven on pilot locations. Crews move market by market, and every site is priced, tracked and closed out the same way, so your team manages one contractor instead of a spreadsheet of them.
- Tiered scopes — each site gets what it needs, priced by tier
- Regional waves — crews, equipment and cranes sequenced market by market
- Built to your standard — your equipment specs and prototype drawings
- One program manager who owns the whole site list
How It Runs
From the first survey to the last site
The same four stages apply to twenty locations or five hundred. Scale changes how many crews run in parallel, not how each site is handled.
Survey & standardize
We verify roof and building conditions, sort sites by type or tier and write one mechanical scope for each, with outliers flagged up front.
Pilot sites
A first group proves the scope, the crew days and the price at real locations. What we learn goes back into the plan before the rollout.
Rollout on your calendar
Work follows your remodel schedule or runs in regional waves. Equipment, cranes and inspections are booked before each site.
Closeout & handover
Each site closes with photos, startup readings, air balance and warranty records, ready for your facilities team.

HVAC and refrigeration only
Rooftop units, ductwork, walk-ins and refrigeration. We are not a general contractor learning rooftops on your sites.
The same job at every site
One scope per site type, one materials standard and one checklist, proven on pilot locations first.
Pricing you can compare
A unit price per site type or tier and a defined process for exceptions, so change orders are rare and explainable.
One point of contact
One program manager and one phone number, no matter how many states the site list crosses.

Frequently Asked Questions
Multi-location mechanical, answered
What does 512 Project Group do?
We are the mechanical contractor for brands with many locations. We run commercial HVAC and refrigeration programs, from rooftop unit, duct and walk-in replacements to remodel scopes, and deliver them the same way at every site.
What kinds of businesses do you work for?
Any brand with more than one address: restaurants, retail, convenience stores, grocery, banks, medical and fitness. We work directly for the brand’s construction or facilities team, or underneath their general contractor.
Do you work outside Texas?
Yes. Programs cross state lines, and who holds the license and pulls the permit in each jurisdiction is settled before a schedule is published.
Who actually performs the work?
512 Project Group holds the contract and manages the program. Work is performed by our sister companies, 512 Mechanical and 512 Refrigeration, wherever their crews can reach, and by vetted licensed trade partners elsewhere — all to one written scope and one closeout standard.
How is a multi-location program priced?
Usually as a unit price per site type or tier, built from a survey and proven on pilot sites, with a defined process for locations that turn out to be different. You see the price per site before the rollout starts.
