Choosing a builder for a commercial plaza
Ask every builder to show you commercial buildings they have completed, ideally ones you can visit. A firm that has only built houses may struggle with deep excavation, heavy column sizes and the sequencing of lifts and services.
Check who will run the site day to day. On a plaza you want a qualified site engineer on site, not just a thekedar visiting once a day. Ask how they manage concrete pours, curing and the quality of sariya on every floor.
- Completed multi-storey work you can see in person
- A named site engineer and a clear reporting line
- Their own shuttering and scaffolding, or reliable hire arrangements
- Experience working alongside a registered architect and structural engineer
Approvals, drawings and contracts
Commercial buildings need approved architectural and structural drawings before work begins. A registered architect (PCATP) and a structural engineer (PEC) must sign them. The approving body depends on where the plot sits: LDA for LDA-controlled areas, DHA building control inside DHA, the Bahria Town planning office in Bahria Town, the Cantonment Board in Cantt areas and the TMA elsewhere. Rules on height, setbacks, parking and fire safety change from time to time, so confirm the current position with the authority before you finalise the design.
Your contract should list the scope floor by floor, the grade of concrete and steel, brick specification, who buys which materials and how payments are linked to completed stages. Keep a retention amount until defects are fixed after handover.
Site supervision and quality checks
Most problems in commercial buildings come from shortcuts that are hidden once the next slab is cast. Independent checks at key stages are worth arranging, even if the builder has their own engineer.
Keep a photo record of steel before every pour and ask for cube test results for concrete. Water leakage, cracking and poor fire exits are expensive to fix in a finished plaza with tenants inside.
- Steel checked against the structural drawings before each pour
- Concrete cube tests at regular intervals
- Proper curing of slabs and columns
- Roof and basement waterproofing tested before finishing
- Fire exits and stair widths checked against the approved plan
