Imagine a business requesting an extra room beside its warehouse. It sends the same length and width to two contractors and receives very different prices. One includes panels only; the other includes a frame, doors and electrical work. This is an illustrative scenario, not a claimed NACE project.
A useful enquiry for a sandwich panel room in Jeddah begins with the intended use: a daily office, equipment enclosure, staff space or store. Dimensions alone do not define what must be supplied.
A comparable quotation needs a defined use, identifiable products and a written installation scope.
Turn the purpose into a brief
Record the occupancy, contents, openings and required services. State whether dimensions are external or clear internal dimensions. Identify connections to existing buildings and any equipment that needs maintenance access.
An insulated panel does not determine an air conditioner’s capacity. Treat cooling and ventilation as separate design requirements that must suit the finished room.
Specify the measurement basis
Floor area and panel quantity are different measurements. Ask how walls, roofs and openings are measured, and whether transport, lifting and waste are included. Do not infer inclusions from an attractive headline rate.
| Item | Clarification to request |
|---|---|
| Panels | Manufacturer, product code, core, thickness, facings and coating |
| Frame and installation | Design responsibility, materials and connection details |
| Services | Doors, power, cooling and drainage: included or excluded? |
Buy an identifiable system
Ruukki’s assembly instructions illustrate why panel joints and fixings are product specific. Ask for applicable product documentation rather than accepting “premium panel” as a specification.
Request approval of any proposed substitution before installation. The proposal should explain what changes in performance, appearance or scope. Record the roof drainage route and connections to the existing building.
Define a useful handover
Agree on material approval, concealed-work records and final acceptance before work begins. Ask the competent specialist to define suitable checks for the agreed scope. A visual inspection alone should not be presented as proof of every claimed performance.
For a NACE enquiry, prepare site photographs, dimensions and intended use, and identify whether you need supply, installation, or both. Mark unresolved structural and drainage questions for inspection instead of silently assuming they are included.
A measurement example behind the price per square metre
Ask suppliers to show the quantity basis when quoting a sandwich panel room in Jeddah. Consider an illustrative rectangular room measuring 4 metres long, 3 metres wide and 2.5 metres high. These invented dimensions explain measurement only; they are neither a completed project nor a purchase quantity.
| Component | Calculation | Illustrative result |
|---|---|---|
| Floor | 4 × 3 | 12 m² of floor area |
| Walls before openings | 2 × (4 + 3) × 2.5 | 35 m² gross wall area |
| Horizontal roof footprint | 4 × 3 | 12 m² before slope and overhangs |
Do not add these figures and treat the total as the panel order. Actual roof dimensions, openings, overlaps and cutting must follow an agreed take-off. Request a separate allowance for waste without assuming a percentage. Identify framing, trims, transport, lifting, installation and tax separately. This makes clear whether a quoted rate buys floor area within a completed room or a square metre of panel, and which additional work each proposal includes.
Questions & acceptance checklist
- Confirm dimensions, openings and intended use.
- Define measurement and exclusions.
- Approve product and frame information.
- Allocate transport and lifting responsibilities.
- Request handover records.
Before you decide
Does a square-metre rate include everything?
Only the written quotation can establish that. Check the frame, services, accessories, transport and tax treatment.
Can room size alone determine panel thickness?
No. Required performance, product data, spans, loading and design details also matter.
When is a site visit important?
When access, lifting, existing construction or service connections affect the scope or installation method.
Prepare a clear scope for your panel room
Share the intended use, dimensions, location and site photos; the quotation will identify the included structure, panels and installation works.
