The solution starts with the building use and site design basis. A quotation review needs the overall dimensions, clear span and column spacing, eave height, doors and openings, crane or equipment requirements, local snow, wind and seismic loads, and the delivery destination. The agreed scope may include structural calculations and drawings, frame fabrication, roof and wall systems, export packing, logistics coordination and erection supervision. The proposal for each project defines the exact supply scope, responsibilities and document package. The ranges in the specification table are typical industry references. Final member sizes, connections, coatings, envelope system, schedule and order volume are determined after the input data are reviewed and are confirmed with the project quotation.
