Quantity Surveyor Agreement (Singapore)

A Quantity Surveyor Agreement in Singapore fixes the respective duties and entitlements of the parties to the arrangement.

The role of a quantity surveyor in Singapore encompasses cost estimation, bill of quantities preparation, tender evaluation, interim valuation, variation assessment, final account settlement, and dispute advisory. On public-sector projects procured through the Government Procurement Act (GPA) and administered by the Building and Construction Authority (BCA), quantity surveyors play an essential role in cost governance and compliance with BCA procurement guidelines. Private-sector projects — including condominiums regulated by the Building Maintenance and Strata Management Act 2004 (Cap. 30C) — similarly depend on quantity surveyors for accurate cost control throughout all project phases from inception to final account.

Under SOPA, any person who carries out construction work or supplies related goods and services (including quantity surveying services) has a statutory right to progress payments. Section 5 of SOPA entitles a claimant to serve a payment claim on the respondent, and section 12 provides for adjudication of payment disputes by an adjudicator appointed by an authorised nominating body such as the Singapore Mediation Centre (SMC) or the Singapore Institute of Architects (SIA). A quantity surveyor agreement that clearly defines the payment milestones and deliverables will reduce the risk of payment disputes under SOPA and provide both parties with a clear framework for interim and final payment certification.

The Accounting and Corporate Regulatory Authority (ACRA) requires that quantity surveying firms operating in Singapore be properly registered as business entities. Quantity surveyors who are members of the Royal Institution of Chartered Surveyors (RICS) or SISV are bound by professional codes of conduct that mandate competence, integrity, and professional indemnity insurance. The agreement should address the quantity surveyor's obligation to maintain current professional indemnity coverage throughout the engagement and for a specified run-off period after project completion.

Singapore's construction sector is overseen by the BCA, which administers the Construction Quality Assessment System (CONQUAS), the Green Mark Scheme, and the buildability and constructability requirements under the Building Control (Buildability) Regulations. Quantity surveyors are expected to be familiar with these frameworks and to advise clients on cost implications of regulatory compliance. The Economic Development Board (EDB) and JTC Corporation, which manage industrial land and facilities, impose specific cost reporting requirements on projects within their estates that quantity surveyors must address in their deliverables.

The Singapore International Arbitration Centre (SIAC) and the Singapore Mediation Centre (SMC) are the primary dispute resolution institutions for construction disputes in Singapore. Quantity surveyors frequently serve as expert witnesses on quantum issues in SIAC arbitrations and Singapore High Court litigation, providing independent opinions on the valuation of works, variations, delay costs, and defects. The agreement should anticipate the possibility of expert witness work and include appropriate fee provisions for dispute-related services.

A Quantity Surveyor Agreement is needed whenever a project owner, developer, or main contractor engages a quantity surveying firm or independent quantity surveyor to provide cost management services for a construction or development project in Singapore.

Project owners commissioning new building works require a quantity surveyor agreement before the design stage begins. BCA requires that projects above certain value thresholds comply with buildability score requirements under the Building Control (Buildability) Regulations, and the quantity surveyor must assess the cost impact of design choices on buildability compliance. Engaging a quantity surveyor without a formal agreement creates uncertainty about the scope of services, fee basis, and professional liability that can lead to disputes during the project lifecycle.

Developers undertaking condominium or mixed-use projects need a quantity surveyor agreement to govern cost planning from feasibility through to final account. The Urban Redevelopment Authority (URA) development charge and differential premium calculations, together with the Stamp Duties Act (Cap. 312) implications of land transactions, require accurate cost estimation that a quantity surveyor provides. The agreement should define the deliverables at each project stage — feasibility cost study, schematic design cost plan, detailed design cost plan, tender documentation, and post-contract cost management.

Main contractors on Design-and-Build projects appoint quantity surveyors to manage subcontract procurement, interim valuations, and variation claims. The SIA Articles and Conditions of Building Contract (Lump Sum Contract, 9th Edition) and the Public Sector Standard Conditions of Contract (PSSCOC) both contemplate the involvement of a quantity surveyor in the administration of the works, and the agreement should reference the applicable conditions of contract.

Government agencies procuring construction works under the Government Procurement Act must comply with the Ministry of Finance procurement guidelines, which require independent cost estimates prepared by qualified quantity surveyors. A quantity surveyor agreement with the appointed cost consultant formalises this engagement and the deliverables expected at each procurement milestone.

Dispute situations also generate the need for quantity surveying services. Parties to adjudication under SOPA, arbitration at SIAC, or litigation in the Singapore High Court frequently engage quantity surveyors as expert witnesses on quantum issues. The agreement should address the quantity surveyor's role as expert, the duty to the tribunal, and the fee basis for expert work. Infrastructure projects funded by the Land Transport Authority (LTA) or the Public Utilities Board (PUB) have additional cost governance requirements that the quantity surveyor must address within the engagement framework.

A properly drafted Singapore Quantity Surveyor Agreement should contain the following elements to protect both the client and the quantity surveying professional.

Parties: Full legal names, UEN registration numbers, and addresses of the client and quantity surveying firm. Where the quantity surveyor is an individual practitioner, the agreement should state their SISV or RICS membership number and professional qualifications. Corporate quantity surveying firms should provide their ACRA registration details and the names of the directors or partners responsible for the engagement.

Project Description: The name, address, and nature of the construction project, the estimated project value, and the project timeline. Reference to the relevant BCA building plan approval number and URA planning permission should be included where available. The description should identify the procurement route (traditional, design-and-build, management contracting, or construction management) and the applicable conditions of contract (SIA, PSSCOC, FIDIC, or bespoke).

Scope of Services: A detailed description of the quantity surveying services to be provided at each project stage — feasibility cost study, cost plan at each design stage, bill of quantities preparation, tender documentation and analysis, tender evaluation report, interim valuations and payment recommendations, variation assessments and instructions, cost monitoring reports, final account preparation and agreement, and any specialist services such as life-cycle costing, value engineering, or tax depreciation schedules. The scope should reference the applicable conditions of contract and the quantity surveyor's role under those conditions, distinguishing between core services and additional services that may be requested during the engagement.

Fees and Payment: The fee basis — whether a percentage of construction cost, a lump sum, or time charges — together with the payment schedule, invoicing requirements, and GST treatment under the Goods and Services Tax Act (Cap. 117A). SOPA payment claim procedures should be referenced, including the 21-day payment response period under section 11(1) of SOPA. The agreement should state whether the fee is inclusive or exclusive of disbursements (printing, travel, specialist subconsultant fees) and the mechanism for fee adjustment if the project scope or value changes significantly.

Professional Standards and Indemnity: The quantity surveyor's obligation to perform services with the skill, care, and diligence expected of a competent quantity surveyor in Singapore, in accordance with SISV and RICS standards of professional conduct. The agreement should require the quantity surveyor to maintain professional indemnity insurance with a minimum cover amount (typically S$500,000 to S$5 million depending on project value) for the duration of the engagement and a specified run-off period of six to twelve years, reflecting the limitation period under the Limitation Act (Cap. 163).

Intellectual Property: Ownership of cost plans, bills of quantities, tender reports, and other deliverables. The client typically requires an irrevocable licence to use all deliverables for the project (including for subsequent phases, modifications, and disputes), while the quantity surveyor retains copyright in the underlying work product and methodology.

Confidentiality and PDPA: Obligations regarding confidential project information — cost data, tender prices, project budgets, and commercial strategies — and compliance with the Personal Data Protection Act 2012 where personal data of project participants, tenderers, or employees is processed as part of the quantity surveying services.

Limitation of Liability: A cap on the quantity surveyor's liability, typically linked to the level of professional indemnity insurance or a multiple of the fee. Exclusion of consequential and indirect loss is common in Singapore construction consultancy agreements but must satisfy the Unfair Contract Terms Act (Cap. 396) reasonableness test where applicable.

Termination: Rights of termination for breach, insolvency, and convenience, together with the quantity surveyor's entitlement to payment for work completed up to the date of termination and reasonable costs of orderly handover. Users of this forms-legal.com template should adapt the termination provisions to their specific project procurement route and the applicable conditions of contract.

Governing Law and Disputes: Singapore law as governing law, with disputes resolved by mediation at the SMC, adjudication under SOPA (for payment disputes), arbitration at SIAC, or litigation in the Singapore courts. The agreement should specify the dispute resolution mechanism clearly, as SOPA adjudication is available only for payment disputes and does not cover other types of professional negligence or breach of contract claims. Under Singapore law, Section 169 of the Companies Act 1967 (Cap. 50) and Section 8 of the Employment Act 1968 (Cap. 91) govern the core requirements for this type of document.
