Risks, Weaknesses & What to Verify
Because promotional claims don’t always translate into consistent delivery, you should verify:
| What to Check | Why It Matters / What to Ask / Inspect |
|---|---|
| Quality of execution vs visuals | Ask to visit 2–3 recent projects they completed locally. Compare materials, finish, junctions vs their portfolio photos. |
| Scope clarity in contract | Precisely define what is included: structural alterations, interiors, MEP (electrical / plumbing), furniture, site supervision, external works. |
| Detailed BOQ / specification sheet | Every material, finish, brand, hardware, thickness, color must be documented so there’s no ambiguity or substitution. |
| In-house vs subcontracted work | Find out which parts (furniture, electrical, plumbing, exterior works) they execute themselves vs subcontract. |
| Supervision & quality checks | Ask how often senior designers / project leads visit the site. What QC checklists are used? How defects or deviations are handled. |
| Payment linked to milestones | Payments should correlate with deliverables / milestones, not arbitrary dates. Include holdbacks or penalty clauses for delays or low quality. |
| Warranty / defect liability | After handover, define the period and types of defects (finishing, plumbing, electrical etc.) they will rectify. |
| Change orders / variation policy | How client requests for changes mid-project are handled, costed, scheduled, and approved. |
| Permits / approvals / structural responsibility | If your project needs structural adjustments or regulatory permission, clarify who takes responsibility and liability. |
