What determines the cost of a factory or warehouse
We do not publish a rate per square metre before seeing a site, because a figure like that is almost always wrong for any specific project. What can be set out up front is what actually moves it.
Why there is no single number
The largest factor in the cost of an industrial building is ground conditions, and ground conditions cannot be read from a drawing or from floor area. Developed estate land may need only shallow footings. Former paddy land a few kilometres away may demand driven piles. The gap between those is large, and only a soil investigation answers it.
A figure quoted before a survey is therefore a guess, and that guess usually returns as a scope variation mid-project. We would rather explain what determines the cost, then build the number once there is data underneath it.
What the scope covers, by building type
Cost follows scope. Comparing quotes without first comparing what is inside them is the most common way to pick the wrong contractor.
| Simple clear-span warehouse | Steel frame, metal roof, concrete floor with hardener, basic MEP, small office. Excludes racking, dock levellers, and sprinklers. |
|---|---|
| Distribution warehouse with docks | Adds dock levellers and shelters, a tighter floor flatness tolerance, commodity-appropriate sprinklers, and container-rated yard paving. |
| General manufacturing plant | Machine foundations, higher electrical capacity, compressed air, process ventilation, and wastewater treatment. Decided entirely by the production process, not by floor area. |
| Food or pharmaceutical plant | Temperature and humidity controlled areas, hygienic finishes, water treatment, and far heavier documentation demands. Cleanrooms push it further still. |
| Commercial and office building | Multi-storey, facade, central air conditioning, vertical transport, and a finish level that matters far more than it does on an industrial building. |
What moves the cost
These eight. Knowing which apply to your project is far more useful than an average taken from somebody else’s.
-
Ground conditions and foundation type
The single largest factor, and the only one that cannot be estimated from drawings. Developed estate land may need only shallow footings; former paddy land in Karawang often demands driven piles. The gap between them is large, and only a soil investigation answers it.
-
Clear height and structural span
Every extra metre of clear height raises steel tonnage, wind load, and erection cost. A wide span with no intermediate columns costs considerably more than a divided one, though it often pays back in pallet positions gained.
-
Floor specification
A general warehouse floor and a floor for high racking with VNA forklifts are two different jobs. A tight flatness tolerance changes the pour method, not just the finish.
-
Power, HVAC, and process utility capacity
Calculated from a real equipment list, not from floor area. Two warehouses of identical size can differ sharply if one is fully conditioned.
-
Fire protection
Driven by the stored commodity and stack height, not building area. The same warehouse with different contents can demand a very different sprinkler system.
-
Wastewater and water treatment
Follows the discharge standard in the Environmental Approval. For industries with process effluent this is a substantial line item, and one often missed in early budgets.
-
Office area fit-out level
Office area costs considerably more per square metre than production area. The office share of total floor area matters more than people usually assume.
-
Location and site access
Regional wages, material logistics distance, and plant access. Projects outside the main industrial belt generally cost more because the local supply chain is thinner.
What a building price never covers
A budget covering only the building is almost always short. These are the line items most often missed.
- Land price, raw land preparation, and perimeter fencing
- Production machinery and its installation, which on a plant project often far exceeds the building cost
- Permitting fees, environmental consultants, and regional levies
- PLN capacity upgrades or a dedicated substation, where estate capacity falls short
- Racking, forklifts, and operational equipment
- VAT and other taxes
- Financing costs and interest during construction
When the number becomes reliable
We always present an estimate together with how firm it is, rather than as a single figure that looks more certain than it is. An estimate given without saying how solid its basis is will change.
| Before any survey | No basis yet. Cannot be called a quote. |
|---|---|
| After feasibility | Grounded in soil data and a layout concept. Enough for an investment decision, not for a contract. |
| After detailed design and BQ | Built from working drawings and a quantified bill. A reasonable basis for a contract. |
Questions about cost
- What does a warehouse cost per square metre?
- There is no honest single figure for this before the site has been seen. The largest cost factor is ground conditions, and that cannot be read from a drawing or from floor area. What we can set out up front is what moves the number: foundation type, clear height, floor specification, electrical capacity, and the fire protection the stored commodity demands. A figure you can rely on comes after a soil investigation and a short feasibility pass.
- What does a factory cost per square metre?
- For a factory, floor area is not even the main determinant. The production process running inside it is: machine foundations, electrical demand, compressed air, process ventilation, and effluent treatment. Two buildings of identical size can cost very differently if their processes differ. That is why we start from the equipment list and production flow rather than from a rate per square metre.
- Why does TCC not quote a figure up front?
- Because a figure quoted before a soil investigation is a guess, and that guess usually returns as a scope variation mid-project. We would rather explain what determines the cost, then build the number once there is data underneath it. That is slower at the start and considerably cheaper at the end.
- When is a number you can rely on available?
- After a feasibility study and soil investigation, an initial estimate can be built for an investment decision. Once detailed engineering and the bill of quantities are complete, it tightens to something fit to base a contract on. We always present an estimate together with how firm it is, rather than as a single figure that looks more certain than it is.
- What is not included in a building price?
- Land, production machinery and its installation, permitting fees, PLN capacity upgrades, racking and operational equipment, VAT, and financing costs during construction. On a plant project the machinery often far exceeds the building cost, so a budget covering only the building is almost always short.
