Quantity surveyor, cost consultant or project manager: which one does your Oman project need?
Owners often ask for one when they need another. Here is what each role actually does, side by side, and how to decide which to appoint for your project.
The three roles side by side
Each role answers a different question for the owner.
| Cost consultant | Quantity surveyor | Project manager | |
|---|---|---|---|
| Answers the question | What will it cost, and what does each decision do to that? | What has been built, what is it worth, what is owed? | Is the whole project on plan, and who is doing what? |
| Busiest stage | Brief to tender | Tender to final account | Brief to handover |
| Core deliverables | Order-of-cost estimate, cost plan, cash-flow forecast, procurement advice | Bill of quantities, tender evaluation, interim certificates, variation valuations, final account | Execution plan, master programme, risk register, monthly client report, decision log |
| Reports to | Owner | Owner (client-side) or contractor (contractor's QS) | Owner |
| Typical fee basis in Oman | Lump sum or percentage of estimated cost | Percentage of contract value or lump sum per stage | Monthly fee or percentage of project value |
| Can one firm do it? | Yes, with the QS role | Yes, with the cost consultant role | Yes, when the firm has both commercial and delivery staff |
When a quantity surveyor is enough
A single villa, a warehouse or a fit-out with one architect and one contractor rarely needs a project manager. What it needs is a bill of quantities so the tender is comparable, someone to check the interim bills, and someone to agree the final account. That is quantity surveying, and it pays for itself on most projects through the variations it prevents and the payments it corrects.
When you need a project manager as well
Add a project manager when there is more than one consultant to coordinate, when the opening date is fixed by a lease or a season, when the owner cannot give the project their own time, or when the project has phases and packages that must land in sequence. The project manager owns the programme and the interfaces; the quantity surveyor owns the money. On larger projects both roles report independently to the owner, which is a useful check.
Why the same firm often does both
Cost and programme move together. A project manager who does not know what a delay costs, or a quantity surveyor who does not know what the programme allows, will each give incomplete advice. Firms that carry both roles can give the owner one monthly report covering scope, cost, time and risk. The condition is independence: the firm must not hold the construction contract, or its advice on cost is compromised.
Common questions
- Is a cost consultant the same as a quantity surveyor?
- Same profession, different stage. Cost consultancy is the budget-setting work before the contract; quantity surveying is the measurement and certification work during and after construction. Most firms, including ours, do both.
- Does a project manager replace the contractor's project manager?
- No. The contractor manages the works. A client-side project manager manages the project for the owner and holds the contractor to the plan.
- Can I appoint a QS after the contractor has started?
- Yes. A commercial health check on the contract, the payments to date and the variations is the usual starting point.
- What does OGB provide?
- All three roles: cost consultancy, quantity surveying through to final account, and client-side project management, from one team in Muscat.
