Start by defining the roles you need
The architect develops and coordinates spatial design; engineers design and inspect structural or services systems; the quantity surveyor manages measurement and cost; the project manager coordinates scope, programme and responsibilities; and the contractor organises construction resources. Boundaries vary with appointment, so put services and deliverables in writing. One person saying “I handle everything” is not evidence that every discipline is covered.
Match the team to the project's complexity. Confirm current professional registration where the work requires it, company status, tax and insurance information relevant to the appointment, and authority to sign. Ask who will actually perform the work, not only who attends the interview. A strong company profile does not guarantee the proposed site team is available.
Verify comparable experience
Request recent projects similar in size, construction type, location and contract arrangement. Speak to clients using contact details independently verified where possible. Ask about final cost versus authorised changes, programme, quality response, communication, safety and defects after handover. Visit a live site and a completed project with permission.
Review key staff, equipment access, subcontractors, workload and financial capacity appropriate to the job. For contractors, inspect sample programmes, method statements, quality records and safety systems. For consultants, review example deliverables with confidential information removed. Evidence of learning from a difficult project can be more useful than a flawless marketing story.
Compare proposals on one basis
- Issue the same drawings, specifications, scope and return schedule to every bidder.
- Separate fees or prices from exclusions, assumptions and programme.
- Clarify who obtains approvals, coordinates disciplines and visits site.
- Check whether taxes, reimbursable expenses and specialist inputs are included.
- Investigate an abnormally low offer rather than celebrating it.
- Score quality and risk transparently before negotiating.
Do not ask one bidder to disclose proprietary detail merely to give it to another. Clarifications should make the proposal understandable, not permit an unfair rewrite after competitors' prices are known.
Use a fair written agreement
Appointments and building contracts should state scope, documents, deliverables, programme, payment, change control, communication, insurance, intellectual property where relevant, suspension, termination, dispute handling and handover. Allocate risk to the party able to manage it. Unrealistic transfer often returns as inflated price or dispute.
Personal trust is valuable, but it works better with clear records. Hold a kickoff meeting, name authorised contacts and establish reporting before work begins. Never lend a professional's name or registration to work they will not control. Obtain project-specific legal and professional advice for the agreements; this checklist helps ask questions but cannot certify a firm or person for your job.
Interview the proposed day-to-day lead, not only senior management. Ask how drawing questions, inspections, samples, cost changes, safety and weekly reporting will be handled. Give the team a small realistic scenario—such as discovering unsuitable soil—and ask who decides, what is recorded and how cost and time are assessed. The answer reveals working habits better than a rehearsed claim of quality.
After appointment, review performance against the agreed deliverables. Prompt feedback and documented corrective action are fairer than storing complaints until the final payment. If a relationship fails, follow the contract's notice and handover process so drawings, site records, materials and responsibilities transfer safely. Selection is important, but active, professional client governance remains necessary throughout the project.
Document conflict-of-interest declarations during selection.
