A site supervisor has a simple task: to make sure the client gets what was agreed and paid for. The supervisor is the housing company's eyes and ears on site, following progress, checking quality, documenting work stages and stepping in before small problems become big ones.
What does a site supervisor do?
- Reviews the designs. Ideally before the contract starts, identifying contradictions and gaps.
- Monitors quality. Work stages are inspected before they are covered up. Waterproofing, joints and penetrations are documented.
- Assesses additional works. Is the work justified, correctly priced and in line with the contract?
- Follows the schedule. Delays are addressed early.
- Keeps records. Minutes from supervision visits are invaluable if disagreements arise.
- Leads the handover. Defects are recorded in a defects list and their repair is followed up.
A good supervisor pays for themselves with a single unjustified request for additional work.
When should a supervisor be brought in?
Supervision brings the most value when the supervisor is involved from the design or tendering stage. They then know the designs and the contract thoroughly before work begins. A supervisor brought in later is still far better than none at all.
Projects where supervision is especially important
New buildings, major renovations, pipe renovations, façade repairs, roofing contracts and balcony renovations. Bathroom renovations too, because waterproofing defects often only show up years later.
Is a supervisor needed if the contractor is competent?
Yes. The supervisor is not there to police the contractor but to represent the client. They make sure both parties interpret the contract the same way, that changes are agreed in writing and that everything is documented. A competent contractor values clear supervision, as good records protect both sides.
Can supervision cover only part of a project?
Yes. The scope of supervision is always agreed per project. The most common options are:
- supervision of the whole project, from design to the end of the warranty period
- supervision of the construction phase, from contractor selection to handover
- supervision of critical work stages, such as waterproofing and concrete pours
- a handover inspection only
What does site supervision cost?
The price depends on the scope of the project, the frequency of site visits and the project duration. A fixed price agreement is often the best option for a housing company, because it can be budgeted in advance.
Example: supervising a pipe renovation
In a pipe renovation of a block of 100 flats, the supervisor attends weekly site meetings, supervises critical work stages and reports to the board monthly. The project typically takes 12 to 18 months. Supervision usually accounts for one to three per cent of the total contract cost.
How to choose a good site supervisor
A good supervisor has hands-on experience of similar projects. Renovation is more demanding than new construction, because existing structures hold surprises and decisions must be made quickly. When requesting quotes, ask how many similar projects the supervisor has done, how reporting works and what happens if a serious defect is found.
Above all, choose a supervisor who communicates clearly, is easy to reach and genuinely looks after the client's interests. Request a quote for site supervision.
