Build an inspection plan that distinguishes code approval, contract acceptance, testing, correction, and warranty handoff.
A modular project has several inspection systems: factory or program oversight, local authority inspections, design-professional observations when required, contractor quality control, owner contract acceptance, and optional independent reviews. One does not automatically replace another.
Build the inspection matrix from controlling documents
List each requirement from approved plans, specifications, contracts, manufacturer instructions, adopted code, permit conditions, and certification programs. Assign the verifier, notice period, evidence, acceptance standard, and hold point. Schedule observation before insulation, finishes, backfill, or module placement hides the work.
Cover every project transition
- Approved document revision and module identification
- Factory records, protected openings, shipment condition, and loose items
- Foundation dimensions, elevations, bearings, anchors, utilities, and drainage
- Delivery damage, placement, connections, bracing, and weather protection
- Structural, envelope, mechanical, electrical, plumbing, and life-safety completion
- Testing, corrections, occupancy, manuals, warranties, keys, and final records
Separate inspection outcomes
| Outcome | What it establishes | What it does not establish alone |
|---|---|---|
| Authority approval | Observed code or permit milestone accepted | Every contract finish is correct |
| Quality-control check | Team followed its defined process | Independent acceptance |
| Owner acceptance | Contract item accepted or listed for correction | Waiver of hidden or warranty rights |
Manage observations and corrections
- Publish the inspection and hold-point schedule.
- Confirm current drawings at the work location.
- Record observations with location and evidence.
- Assign each discrepancy and due date.
- Reinspect before concealment or payment.
- Close records into occupancy and warranty files.
Prevent evidence from disappearing
- Photographs without date, location, revision, or subject
- Correction covered before reinspection
- Factory and site teams assuming the other owns a connection
- Final payment before manuals, approvals, and open-item status are reconciled
Deliver a usable closeout package
Organize approved plans, permits, inspection results, test reports, photographs, equipment information, serial numbers, startup records, correction closure, occupancy documentation, warranties, maintenance requirements, contacts, and unresolved warranty items. The file should let a future owner understand what was accepted and how to operate it.
