Pricing, inclusions and timing
Each project is quoted against its design, quantity, fit-out and site requirements. Compare factory supply and site costs separately. Ask the written quotation to identify the inclusions, exclusions and responsible party for each item below.
Allow for design and scope confirmation, approvals and engineering, procurement, manufacture and inspections, then delivery and installation. Site preparation and service connections need to be coordinated with the factory programme. Dates are confirmed for your project after reviewing capacity, materials and site readiness.
Send the site address, intended use, preferred layout, quantity, access information and target delivery date. Drawings and a finish schedule help define the scope. If the brief is still developing, share what you have so the remaining decisions can be identified.
