PEB (Pre-Engineered Building) Construction · Question

What documents should I collect from the PEB supplier at handover?

Short answer

Collect the as-built drawings, structural design basis, material test certificates, bolt and coating records, inspection and test reports, erection completion records, warranty terms and an operation and maintenance guide. Do not release the final payment until the agreed set is in your hands, and keep it organised for lenders, insurers and future modifications.

In more detail

The handover pack is the permanent record of what was built. When you later want to extend the shed, claim under a warranty, answer an insurer or show a lender the asset, these papers are what everyone asks for.

Agree the list at the start of the contract, so the supplier knows from day one what must be produced. Leaving it for the last week usually means missing items and arguments.

As-built drawings showing the structure as erected, with member marks and anchor layout
Design basis and calculations summary, with the standards and loading assumptions used
Mill test certificates and traceability index for major steel
Records for coating, galvanising or paint, and for bolts and fasteners
Factory inspection and site erection checks, including alignment and tightening records
Sheeting and accessories data, with product and sealant details
Written warranties, with start dates, scope and conditions
Maintenance guidance for cleaning, gutters and roof checks

A pack that paid for itself

An owner wanted to add a mezzanine two years after handover. Because the design basis and as-built drawings were on file, the engineer could assess the frame quickly. Without them, a costly investigation would have been needed first.

Walk the building against the drawings, review the pack for gaps, and record any pending items in a short written list with dates. Tie the final instalment to completion of that list.

Key points

As-built drawings and the design basis are the most valuable documents for later changes.
Material certificates and test records support traceability and insurance questions.
Warranty papers should state scope, start date and conditions clearly.
Agree the handover list in the contract, not at the end of the work.
Link final payment to receipt of the complete document set.

Who this applies to

Owners taking over a newly erected factory or warehouse.
Finance and project teams who must file asset records for lenders or insurers.
Facility managers inheriting a building and needing records for maintenance.
