- Design-build & plan-and-spec delivery
- BIM execution-plan and coordination review
- Load-basis and equipment-selection responsibility
- Fabrication capability and capacity confirmation
- Spool drawings & prefab assemblies
- Multi-trade coordination with partner companies
- TAB and commissioning responsibility matrix
- Post-construction maintenance handoff
The J3 process: estimate to commissioning
The project workflow should define estimate basis, design responsibility, approved documents, BIM coordination, procurement, fabrication, installation, controls, startup, testing, commissioning support, training, and closeout. The actual responsibilities and acceptance criteria are project-specific.
BIM and coordination requirements
Confirm the BIM execution plan, software and version, model ownership, levels of development, clash responsibility, fabrication use, issue dates, approvals, record model, and relationship to signed contract documents. No software, clash, change-order, or fit outcome is claimed without project evidence.
One campus, coordinated trades
The site identifies related Beyer Plumbing, Beyer Electrical, J3 Automated Systems, and Velocity Sheet Metal entities. Confirm the participating companies, facilities, scope, capacity, contractual relationships, and responsibility matrix for the proposed project.
Built for GCs and owners alike
General contractors, owners, and developers can submit project documents, delivery method, facility type, location, bid date, design responsibility, schedule, procurement requirements, and decision contacts for eligibility review.
