Ask five contractors what building construction cost per square feet in Bangladesh should be and you will get five numbers, all defensible and all incomplete. A per-square-feet rate is a summary of dozens of decisions, and quoting one before those decisions exist is guesswork dressed as a budget. Below is how our engineers build a real number — and what makes yours move.
The Foundation Decides More Than the Finishes
On a plot with competent soil close to the surface, a shallow footing may be enough. On soft alluvial ground — common across Dhaka's newer neighbourhoods — the same building may need piles twenty-five metres deep. That single difference can move the total by a wide margin before a single wall is built, which is why a soil test in Dhaka is the cheapest budgeting tool available to any owner.
What Sits Inside a Per-Square-Feet Rate
- Substructure: soil investigation, piling or footings, pile caps and grade beams.
- Superstructure: RCC frame, slabs, staircases, shear walls and reinforcement percentage.
- Envelope and partitions: masonry, plaster, waterproofing, glazing and external finish.
- MEP: electrical, plumbing, fire protection, lift and generator provisions.
- Finishes: floor, door, window, kitchen and sanitary specification — the widest-swinging item of all.
- Preliminaries: site setup, safety, supervision, testing, insurance and contingency.
Four Site Factors Owners Underestimate
Access is first: a narrow lane in an old area limits truck size and pump reach, and every constraint has a cost. Second, neighbours — building within metres of an occupied structure rules out vibration-heavy methods and pushes you toward bored piles. Third, the water table, which decides dewatering and waterproofing scope. Fourth, storey count, because taller structures need heavier columns, deeper foundations and more of the vertical services that per-square-feet averages hide.
Specification Is Where the Rate Really Moves
Two buildings with identical structures can differ substantially once finishes are chosen. Local versus imported tiles, standard versus premium sanitary ware, aluminium versus uPVC windows, a basic lift versus a branded one — these choices are usually where an owner's budget is genuinely decided. Fixing your specification early converts a range into a rate.
How to Get a Number You Can Trust
Commission a soil investigation, get a structural design based on that data, and then ask for a priced bill of quantities against a written specification. A per-square-feet figure derived from those three documents is a budget. One quoted over the phone is an opening position, and the gap between them is usually discovered halfway through construction.
