Design-to-delivery handoffs for modular projects
Modular projects fail at handoffs: design to factory, factory to transport, transport to site, site to finishing. Define owners, documents and checkpoints at each one.
A modular project moves through four handoffs: design to factory, factory to transport, transport to site, and site assembly to finishing. At each, define who owns the next step, which documents pass across, and what must be checked before work continues.
Handoff 1: design to factory
The factory needs a frozen, coordinated drawing set: architecture, structure, services, finishes. Record what "frozen" means and the cost of changes after it (design freeze). Confirm approvals with the engineer of record and local authority before production.
- Documents: drawings, specifications, schedules, approved submittals.
- Check: every party has acknowledged the revision in writing.
Handoff 2: factory to transport
- Documents: inspection records, packing list, lifting and handling instructions.
- Check: pre-shipment inspection against the quality plan (quality records).
- Agree who insures, and the damage reporting method.
Handoff 3: transport to site
- Documents: delivery schedule, site access plan, unloading plan.
- Check: the foundation is ready, within tolerance, and the crane is booked (foundation interfaces).
- Receive and inspect on arrival (receiving).
Handoff 4: assembly to finishing
- Documents: as-built information, connection records, test results.
- Check: joints sealed, services connected and tested, defects listed.
Make it contractual
Write each handoff into the contract with an owner, a checklist and an acceptance signature. Note who decides when drawings conflict. The turnkey evaluation guide and prefab exclusions show where gaps appear.
Keep one record
A single shared log of drawings revisions, decisions and open questions avoids version disputes. Timelines for each stage vary by project; ask for a written one.
Questions people ask
What is a handoff?
The point where responsibility and information pass from one party or stage to another.
Why do handoffs matter more in modular work?
Because factory production begins early and changes late are costly.
What is the key document?
A frozen, coordinated set of drawings and specifications that every party has acknowledged.
Who coordinates?
Name one coordinator in the contract.
