A useful PEB scope connects the primary steel frame with secondary members, connections, bracing, roof and wall build-up, openings, drainage, insulation and the planned installation sequence. Requirements depend on the confirmed design basis, building use, span and height, applicable environmental loads, equipment and site interfaces. Avoid fixing member sizes or assuming one standard bay layout until the responsible design team has reviewed the project information.

For steel fabrication, agree the approved drawings, material grades and thicknesses, connection and welding details, tolerances, inspection points, identification and traceability requirements, dispatch sequence and documentation. For roofing and cladding, coordinate profile, coating, fixing, laps, flashings, gutters, penetrations, ventilation and maintenance access. If hot-dip galvanization is required, assess part geometry, venting and drainage, handling and the applicable coating specification before fabrication is finalized.

When reviewing commercial offers, compare equivalent scope. Engineering, supply, fabrication, coating, transport, lifting equipment, erection, civil works, electrical systems, permits and handover documentation may be included or excluded differently. Ask the proposal to list assumptions, deliverables, interfaces and exclusions explicitly so the project team can compare offers on a consistent basis.
