Service 08

Client side quantity surveyor

The number, and what it means for the decision in front of you

A client side quantity surveyor is the surveyor appointed by you rather than by the contractor. The measurement is the same discipline either way. What differs is who the answer is for, and whether anybody tells you what the answer means before you commit to it.

The problem

A measured number is not the same as commercial advice.

One side of the appraisal is tested. The other is not.
Value is checked against public sales data more or less continuously. Build cost is usually carried forward from the last scheme, and it carries no date.
How often each side of an appraisal is retested Two tracks across the same two year period. Gross development value carries nine test points, roughly one a quarter, because comparable sales are public. Build cost carries a single test point at the start and nothing after it, so the figure reaching tender is the one set two years earlier. Gross development value tested against public sales data, about quarterly Build cost set once, then carried forward same figure, two years on the last scheme this tender

Most developers who have been disappointed by a quantity surveyor were not let down by the arithmetic. They were given a figure and left to work out for themselves what it meant.

Measurement is a technical discipline with published standards behind it, and it is done to a consistent quality by most of the profession. That is precisely why it is the wrong thing to buy on its own. Two surveyors measuring the same drawings will produce broadly the same quantities. What separates them is whether anybody tells you which of the assumptions behind those quantities is fragile, what happens to the figure if the ground turns out differently, and whether the decision you are about to take is the right one at all.

The pattern repeats. A cost plan arrives as a spreadsheet with a total at the bottom and no statement of what it excludes. A tender report ranks four bids by price without normalising the qualifications that make them incomparable. A monthly valuation certifies close to what was applied for, because checking it properly takes longer than the fee assumed. None of that is incompetent. All of it leaves the developer holding a number they cannot interrogate.

The second failure is timing. A surveyor brought in to measure a finished design is doing arithmetic on decisions that were taken months earlier, when they could still have been changed cheaply. By the time the quantities exist, the structural solution is fixed, the specification is written and the procurement route is chosen. Every one of those decisions moved the cost more than the measurement ever will.

The third failure is the report that cannot be acted on. A monthly document that states a certified figure, a forecast and a variance, with no view on which of those numbers is soft and what would close it, describes the past accurately and helps with nothing. What a developer needs each month is short and awkward: what has moved, what is going to move, and what decision is now due. That is a harder document to write, because it commits the person writing it to a position.

The difference

Where the advice is worth more than the measurement.

Five decisions taken before anybody opens a measurement package. Each moves more money than any rate in a bill of quantities, and none of them is a measurement question.

Decision 01

The structural solution

Two frames reach the same floor area and both price correctly. Which carries programme risk, which depends on a single supplier, and what the difference in duration does to finance cost across eighteen months appears in neither set of quantities.

Decision 02

The procurement route

Single stage or two stage, both legitimate, measurement identical. What changes is where the competition sits and how much of the price is genuinely fixed at the point you are committed.

Decision 03

The contingency

A round percentage looks prudent and tells you nothing. Built against identified events, each with a value and a release trigger, it can be spent deliberately and defended to a funder line by line.

Decision 04

The qualification at the back of a tender

A paragraph moving ground risk back to the employer is English, not a number. It appears in no measured quantity and is frequently the most expensive item in the document.

Decision 05

The provisional sum nobody defined

Defined means the contractor has priced its effect on programme and preliminaries. Undefined means they have not, and both follow later. The two look identical in a total and behave very differently once instructed.

Decision 06

The pricing document itself

A contract sum supported by three lump sums leaves nothing to value a change against. The breakdown you specify before tenders go out decides how every variation for the next two years gets priced.

None of this needs unusual technical skill. It needs an appointment whose purpose is to give you an opinion rather than to produce a document, and somebody with no commercial reason to keep that opinion comfortable.

What we do

An independent quantity surveyor who gives you the opinion as well as the figure.

The measurement is the foundation. The advice is the product.

The industry label for this appointment is the professional quantity surveyor, usually shortened to PQS, meaning the surveyor engaged by the client rather than by the builder. We will use plain terms from here, because the label describes who signs the fee note and tells you nothing about what you receive.

Method 01

Measured scope, not remembered rates

Quantities to NRM1 at cost planning stage and to NRM2 where a bill is required, so figures trace to a standard. Set out on our cost planning and take-off pages.

Method 02

A stated position, not just a total

Exclusions and assumptions on the face of the document rather than in an appendix. Where an assumption is doing a lot of work we say so, and what would establish it. Where a figure is not safe to commit against, we say that too.

Method 03

Monthly, against the works

Valuations made against work genuinely in place. Variation assessment tests entitlement before value, because answering both together is how a change becomes a claim.

Method 04

Reporting for the people who read it

A board paper and a funder’s drawdown pack ask different questions of the same figures. A position certified properly each month survives examination by a lender’s monitoring surveyor without argument.

Method 05

Closing the account

Final account negotiation starts from a record built during the job rather than reconstructed afterwards. Where it will not settle it moves to final accounts and disputes with the evidence already in order.

Method 06

Independence by structure

No design fees, no contractor relationships, no software licences to sell. One side of a project only, never a lender and a developer on the same scheme. One senior lead from first budget to final account.

What we produce

Six outputs a construction cost consultant for developers should be able to hand over.

Each is written to go to a board, a lender or a joint venture partner without a covering explanation.

Output 01

Cost plan to NRM1

An elemental cost plan that develops with the design and is reissued at each stage with a reconciliation showing what changed, why, and whether it was design development or scope creep. The exclusions and assumptions are stated on the face of the document, because a number without them is not advice.

Output 02

Bill of quantities to NRM2

Measured quantities a contractor can price and cannot later reinterpret. Where the design is incomplete, the gaps are identified and filled deliberately rather than quietly, and each assumption is recorded so it can be tested when the drawings catch up.

Output 03

Tender analysis

Bids normalised to a common basis so the comparison is genuine, with qualifications and exclusions pulled out and priced rather than left in the appendices. The cheapest tender and the lowest out-turn cost are frequently different bids.

Output 04

Interim valuations

Monthly valuation of work genuinely in place, with the report stating the forecast out-turn, the changes assessed and the items still open. Valuing against an application rather than against the works is the most common way a project overpays quietly for two years.

Output 05

Variation assessment

Each change valued under the contract, with the entitlement tested before the value is discussed. Granting an extension of time and agreeing to pay for it are two separate decisions, and merging them is expensive.

Output 06

Final account negotiation

The account assembled, tested and settled, with changes reconciled against what was instructed and what was built. Where it will not settle, the record is already built well enough to argue from.

Why developers call

Three situations that bring a developer to this page.

Scenario 01

The budget that was never a budget

A figure taken from a previous scheme, carried into an appraisal, then repeated in board papers until it became the number everybody believed. Nobody wrote down what it excluded. Our hidden cost exposure scenario deals with what surfaces when that figure is finally tested against measured scope.

Scenario 02

Quantities nobody checked

The contractor's quantities were accepted because checking them looked like duplication, and because everybody assumed somebody else had. The consequence appears at remeasurement or at final account, by which point the works are built. This is the subject of our quantity assumption risk scenario.

Scenario 03

A tender that looked competitive

Four returns, one clearly cheapest, and a set of qualifications in the back of it that moved risk back onto the employer without anybody pricing the transfer. Normalising the bids turns four different documents into one comparison, and it usually changes the ranking. Where the documents themselves created the opening, our tender documentation gaps scenario applies.

Most of this work sits on housing, apartment and mixed use schemes. If that is your territory, the residential development page describes how the commercial position usually runs, and the borrower side page sets out how we work with developers and private investors specifically.

Questions

Appointing a quantity surveyor, answered directly.

What does a client side quantity surveyor actually do?

Two things, and the second is the one that matters. The first is measurement and valuation: building the cost plan, measuring the works, testing tenders, valuing what has been built and settling the account. The second is telling you what those numbers mean for the decision in front of you, which is where the exposure sits and what would have to be true for the figure to hold. A surveyor who only does the first is doing arithmetic on decisions you have already taken.

Is this the same as the contractor's quantity surveyor?

No, and the distinction is worth being blunt about. Both use the same measurement standards and both are competent professionals. The difference is who they are paid by and what they are paid to achieve. The contractor's surveyor is there to maximise and defend the contractor's account, which is a legitimate job. An independent quantity surveyor acting for you is there to test it. Every valuation has both sides present, and if only one of them is represented the outcome is predictable.

Do I need one on a design and build contract?

Yes, and arguably more than on a traditional contract, because on design and build the consultants who wrote your specification are usually novated across to work for the contractor. Where the appointment also carries authority to instruct and certify, the role is called the employer's agent, and we set that out on our employer's agent page. The measurement discipline is the same either way. What changes is the authority: without being named in the contract, a surveyor can advise you but cannot instruct, certify or bind anybody, and the contractor is entitled to treat their view as an opinion rather than a decision.

At what project size is it worth appointing one?

The threshold is complexity rather than value. A straightforward scheme at several million pounds may need less commercial attention than a phased refurbishment at a fraction of that, where the unknowns sit behind existing fabric and the contract has to allocate them. If the commercial position is simple, we will say so rather than propose a fee against it. What raises the threshold is anything that makes the scope hard to describe: existing fabric, phased handovers, a live building, a specification driven by an end user who has not signed yet, or a procurement route that fixes the price before the design supports it.

How do you charge?

Full lifecycle appointments are usually a percentage of construction value. Defined pieces of work, for example a cost plan at feasibility or a tender analysis, are quoted as a fixed sum. Expert and dispute work runs at a day rate. The basis is agreed and written down before anything begins, with the exclusions stated rather than left to be discovered. Where a scheme runs materially longer than the programme the fee was priced against, we raise it at the time and agree the position, rather than presenting it afterwards as an additional account.

Can you take over a project that has already started?

Yes, and a good part of the work arrives that way. The first exercise is establishing where the position actually stands, which is rarely where the last report said it stood: what has been certified, what has been instructed but not valued, what has been claimed and what is genuinely still open. That reconciliation is uncomfortable to read and it is the only honest starting point. We would rather deliver that in the first fortnight than issue a comfortable report that agrees with the previous one and defers the problem to the final account, where it costs considerably more to resolve.
