Definition

In an APC context, a client brief for quantity surveying services sets out the client's project objectives, scope, agreed fee, programme, and communication arrangements. It forms part of, or accompanies, the terms of appointment. The RICS Rules of Conduct require clients to receive a written record of the services to be provided; the brief fulfils that obligation.

Why this matters for Client Care

  • A clearly articulated brief prevents misalignment between the client's expectations and the QS's deliverables, which is one of the primary causes of fee disputes on construction projects.
  • Recording the client's budget at the outset creates the baseline against which cost plans and value engineering decisions are measured throughout the project.
  • The brief identifies the reporting structure and communication preferences, enabling the QS to tailor their approach to the individual client.
  • Assessors expect candidates to demonstrate how they obtained and used a client brief in a real project, not merely describe the concept in the abstract.

Key principles

Capturing the client's objectives and constraints

The brief should record the client's primary objective (cost certainty, speed, sustainability), the budget as a hard cap or range, and any cost-sensitive items. Constraints such as programme milestones, planning conditions or tenant fit-out obligations should be noted, as they influence procurement advice and risk allocation.

Defining the QS scope within the brief

The brief should state which QS services are included (initial cost appraisal, elemental cost plan, Bills of Quantities, tender analysis, contract administration, final account) and which are excluded. Each included service should reference the programme stage at which it will be delivered.

Fee, communication, and reporting arrangements

The brief should record the agreed fee and its basis (percentage of construction value or fixed lump sum). The reporting cadence (monthly cost reports) and communication method (email, site meetings, project extranet) should be agreed and recorded from the outset.

Conflict of interest and confidentiality

Before accepting the instruction, the surveyor must check for conflicts of interest, particularly where a relationship with a contractor or subcontractor could compromise objectivity. The brief should confirm that no conflict exists, or document how any conflict has been managed under the RICS Conflicts of Interest global professional statement. Project information must be kept confidential.

Relevant RICS guidance and legislation

  • RICS Rules of Conduct (effective 2 February 2022) — Rule 3 (Service) requires written confirmation of the services to be provided and the basis of the fee.
  • RICS standard form terms of appointment — the standard form is designed for use alongside a scope of services document and provides tested provisions for fee, liability, and dispute resolution.
  • RICS Conflicts of Interest global professional statement (1st edition, 2017, effective 1 January 2018) — governs the identification and management of conflicts of interest on construction and refurbishment projects.
  • Consumer Rights Act 2015 — applies where the client is a consumer; pricing and service information must be transparent and intelligible.

Ethics and Rules of Conduct angle

A client brief is an expression of Rule 3 (Service): the surveyor must understand what the client needs and deliver against it. Rule 1 applies where the brief records budget or programme constraints that the QS must not misrepresent in subsequent cost plans. Rule 2 (Competence) is engaged where the brief includes QS tasks in areas where the candidate is not yet competent; the scope should either be restricted or a suitably qualified supervisor identified.

APC-style Q&As

Q (Level 1) What is the purpose of a client brief in a quantity surveying instruction?

A client brief records the client's project objectives, budget, programme, and the agreed scope of QS services, creating a shared written baseline against which the surveyor's performance can be measured and disputes can be resolved.

Q (Level 1) At what stage in a project should the client brief be agreed?

The brief should be agreed and signed before substantive work begins, so that the QS has a clear instruction and the client has a documented understanding of what they will receive. Starting work without a written brief exposes both parties to misunderstanding and potential dispute.

Q (Level 2) On a refurbishment project, how would you structure the client brief to capture both the client's cost objectives and the reporting arrangements you intend to use?

(example) On a recent office refurbishment I prepared a brief that opened with the project scope and the client's primary objective, which was to complete within a hard budget ceiling without deferring any of the specified fit-out elements. I then set out the QS services to be provided at each RIBA stage, the fee basis, and the reporting structure, which was a monthly cost report issued five working days before each project meeting. The brief was reviewed with the client at the kick-off meeting, any amendments were agreed, and both parties signed the final version before the feasibility cost plan was commenced.

Q (Level 2) A client asks you to proceed with a QS instruction before the brief has been finalised. How do you respond?

I would explain that commencing work without a written brief creates risk for both parties: the client has no documented assurance of what will be delivered, and I have no clear instruction against which to measure my performance or justify my fee. I would offer to prepare a concise interim brief covering the immediate scope and budget, so that work can begin promptly whilst the fuller terms of appointment are finalised. I would not commence substantive work without at least that interim written record in place.

Q (Level 3) Partway through a refurbishment project you discover that your firm has a commercial relationship with the main contractor that you were not aware of when you accepted the instruction. How do you handle this?

(example) I would immediately disclose the relationship to the client in writing, explaining its nature and the potential effect on my objectivity. Under the RICS Conflicts of Interest global professional statement, any conflict must be disclosed promptly and managed transparently. In consultation with my firm's compliance officer, I would assess whether safeguards (excluding the contractor from tender, having a colleague review my cost assessments) were sufficient, or whether the conflict required me to withdraw. The client's informed decision would be the determining factor.
