| Project and application | Project location, building type, construction sequence, and intended use of the formwork. | Cast-in-place reinforced-concrete residential building; formwork reused across typical floors. | Written confirmation of the proposed system’s intended applications, limitations, and required accessories. |
| Structural geometry | Wall, column, beam, and slab dimensions; floor-to-floor height; openings; corners; and changes in layout. | Provide dimensioned drawings and identify typical, transfer, and non-typical levels separately. | Panel layout drawings, shop drawings, and a component schedule coordinated with the latest project drawings. |
| Concrete and design loads | Concrete density and mix, placement rate, pour height, temperature, vibration method, and construction loads. | Set project-specific values with the structural engineer and concrete contractor; do not use a generic pressure assumption. | Design calculations showing the assumed loads, load combinations, support arrangement, and design criteria. |
| System and material | Select a suitable system, such as timber-beam, steel, aluminum, or modular panel formwork, based on geometry and site conditions. | Compare system weight, handling method, available crane capacity, labor skills, and expected reuse conditions. | Material grades, component dimensions, connection details, surface finish information, and product data sheets. |
| Deflection and concrete finish | Specify acceptable formwork movement and the required concrete surface finish for each element. | Identify whether surfaces will be exposed, painted, tiled, or covered by another finish. | Design checks against the project’s stated deflection and finish criteria, plus details for joints and tie-hole treatment. |
| Supports and stability | Define prop spacing, shore height, bracing, anchorage, bearing surfaces, and reshoring sequence. | Check the actual site layout, floor capacity, ground conditions, and temporary works sequence. | Support and bracing layouts, installation guidance, and calculations for the proposed site configuration. |
| Compatibility and interfaces | Check compatibility with reinforcement, embedded items, construction joints, safety platforms, and adjoining systems. | Mark lift openings, service penetrations, slab edges, and any areas with congested reinforcement on the drawings. | Coordinated drawings and a clear list of included, excluded, and separately supplied components. |
| Quantity and reuse plan | Estimate the required formwork area, peak concurrent demand, construction cycle, and planned reuse sequence. | Base quantities on pour schedules and floor layouts rather than total building area alone. | A quantity takeoff with assumptions, spare-parts allowance, and a realistic reuse and maintenance plan. |
| Quality and traceability | Set inspection requirements for dimensions, welds, coatings, fasteners, and incoming materials. | Agree acceptance criteria and inspection points before production begins. | Inspection records, material certificates where applicable, traceability information, and pre-shipment inspection access. |
| Delivery and documentation | Confirm delivery location, packing method, shipment schedule, unloading arrangements, and required documents. | Coordinate delivery dates with the construction programme and site storage capacity. | Packing list, component labels, installation and safety instructions, maintenance guidance, and agreed delivery schedule. |
| Commercial scope and support | Clarify supply scope, engineering responsibilities, spare parts, warranty terms, and technical support arrangements. | Record responsibilities for design review, installation supervision, and changes caused by revised drawings. | A detailed quotation with exclusions, service scope, response arrangements, and documented change-control terms. |
