Frequently Asked Questions

What does the builder program include and how does a GC enroll?

The builder program is available to general contractors, production builders, and design-build firms with two or more active lots or projects in a calendar year. Enrollment includes a dedicated project manager assigned to your account, volume pricing locked at contract execution, priority scheduling for rough-in and trim-out phases, and a standing RFI log maintained by our builder liaison. Schedule a builder consultation at (909) 655-5646 to review qualification criteria and current program availability.

How do you handle RFI support and submittal log documentation?

Our builder liaison maintains a running RFI log for every active project and responds to RFI entries within one business day. Equipment schedule submittals are prepared in your preferred format at the permit set stage and updated if equipment specifications change before rough mechanical. All submittals include model numbers, load calculations, and installation sequence notes compatible with standard submittal log formats used by GC project management platforms.

What is included in the closeout documentation package?

The closeout documentation package includes the commissioning report with measured system performance data, a completed punch list sign-off, warranty start date, manufacturer equipment registration confirmation, a homeowner maintenance schedule, and a copy of the final inspection approval for the HVAC scope. This package is delivered to the builder superintendent before the punch walk so your certificate of occupancy documentation is complete prior to key delivery.

Do you work on both production builder schedules and custom home builds?

Yes. Our new construction division is structured to support both production builder volume schedules — where consistent rough-in timelines across multiple lots are the priority — and custom home builds, where plan review, architect coordination, and equipment selection require more pre-construction engagement. Custom builder clients receive plan review support at permit set and a dedicated project manager who coordinates directly with the architect of record on equipment schedule submittals.

How are change orders managed on active projects?

All change orders are issued in writing before any out-of-scope work proceeds. Our project manager documents the scope change, revised cost, and schedule impact, and routes the change order through your preferred approval process. No verbal approvals are accepted as authorization. This applies to both field-generated changes identified during rough-in and owner-directed design changes submitted through the architect or design-build coordinator.

What service area do you cover for new construction and remodel projects?

Robert & Sons Fontana Builders serves general contractors and builders throughout Fontana, CA and the broader San Bernardino County market, including Ontario, Rancho Cucamonga, Rialto, and surrounding Inland Empire jurisdictions. For multi-phase or high-volume builder programs outside this primary radius, coverage availability is reviewed during the builder consultation. Contact us at [email protected] or call (909) 655-5646 to confirm jobsite coverage for your active lot addresses.
