| Relevant project experience |
Completed projects comparable in building use, structural system, climate, and installation conditions. |
Project descriptions, scope of work, completion records, and references that can be contacted with permission. |
Experience with a different type of modular building may not transfer directly to the buyer’s project. |
| Engineering and code compliance |
Design documents prepared for the project’s destination, including applicable structural, fire, energy, and life-safety requirements. |
Design drawings, calculation packages, material specifications, and a clear list of applicable codes and approvals. |
Building requirements vary by location and intended use; factory production does not replace local approvals. |
| Quality management |
Documented procedures for incoming materials, production checks, nonconformities, and final inspection. Any claimed certification should cover the relevant site and scope. |
Current certificate details, inspection plans, sample quality records, and corrective-action procedures. |
Consistent, documented checks help identify defects before modules leave the factory. |
| Factory capability and capacity |
Production equipment, trained staff, and available capacity suited to the proposed module size, materials, and schedule. |
Factory audit or live video tour, production workflow, capacity statement, and schedule showing planned production stages. |
Declared capacity should be assessed against the actual order and current workload, not treated as a guarantee. |
| Materials and durability |
Specified structural and finish materials with traceable product information and suitability for expected environmental exposure. |
Material schedules, technical data sheets, test reports where applicable, and maintenance requirements. |
Material selection affects service life, maintenance, comfort, and performance in the project’s climate. |
| Testing and inspection |
Inspection and testing requirements defined for the project, with results recorded and linked to the relevant products or production batches. |
Inspection and test plan, sample reports, acceptance criteria, and procedures for resolving failed results. |
Clear acceptance criteria reduce ambiguity during factory checks and handover. |
| Transport and installation planning |
Practical coordination of module dimensions, lifting points, transport routes, site access, foundations, and installation sequence. |
Transport drawings, lifting plans, packing details, installation method statement, and a responsibility matrix. |
A factory-ready module still needs to be safely transported and correctly connected on site. |
| Schedule and project coordination |
A realistic programme covering design approvals, procurement, production, inspection, shipping, and site installation. |
Milestone schedule, customer-input list, change-control process, and named project contacts. |
Delays can arise from design changes, approvals, logistics, or site readiness—not only factory production. |
| Quotation transparency |
A clear distinction between included work, exclusions, assumptions, optional items, and costs that depend on final design or destination. |
Itemised quotation, scope matrix, payment milestones, warranty terms, and written change-order process. |
Comparable quotations require aligned scope; a low initial price may omit important services or site work. |
| After-sales support and warranty |
Written warranty coverage, a process for reporting defects, and defined support responsibilities after delivery. |
Warranty document, response procedure, spare-parts policy where relevant, and service contact details. |
Clear post-delivery responsibilities support maintenance and defect resolution. |
