Dispute Resolution in Construction Industry Singapore

A withheld progress payment, a contested variation or a delay claim can stall cash flow, strain relationships with subcontractors and put a project timeline at risk. Construction disputes are rarely just legal problems, which is why the way they are resolved matters as much as who is right.

Singapore offers a layered system for dispute resolution in construction industry projects, from mediation and statutory adjudication to arbitration and the courts. This guide explains how each option works, how they compare and what to put in place before a dispute escalates.

Dispute Resolution in Construction Industry

Dispute resolution in construction industry refers to the contractual and statutory processes used to settle claims arising from a building or infrastructure project, such as payment, variation, delay and defect disputes.

Arbitration clauses are a staple of construction contracts in Singapore, but they sit within a wider range of alternative dispute resolution methods and court options. The methods below run from the least to the most formal.

1. Negotiation

Direct negotiation between the parties, often at contract administrator or senior management level, is the first step in most tiered clauses. It is the cheapest option, but it produces a binding outcome only if the parties record the settlement in writing.

2. Construction Mediation

Construction mediation is a voluntary and confidential process in which a neutral mediator helps the parties reach their own settlement. The Singapore Mediation Centre (SMC) has handled construction disputes since 1997, and the Singapore Contractors Association (SCAL) launched the Singapore Construction Mediation Centre for disputes where at least one party is a SCAL member or a listed trade subcontractor.

Mediation may help preserve working relationships, although it does not guarantee that outcome, and it binds the parties only once a settlement agreement is signed.

3. Expert Determination

Expert determination refers a defined technical or valuation issue, such as the cost of defects or the value of variations, to an independent expert. Whether the expert’s decision is final depends on the contract, so the clause should say so expressly. SMC also offers neutral evaluation.

For large infrastructure projects, the Singapore Infrastructure Dispute-Management Protocol (SIDP) provides for a dispute board that follows the project and can mediate, give an opinion or make a determination. It is recommended for projects above S$500 million.

4. Adjudication Under SOPA

The Building and Construction Industry Security of Payment Act 2004 (SOPA) gives parties who carry out construction work, or supply related goods or services, a statutory right to progress payments. It also creates a fast adjudication process when a payment claim is disputed.

The determination has only temporary finality, so a losing respondent can challenge it in court, but only after the adjudicated sum is paid in first. The stages and deadlines are covered in the SOPA section below.

5. Construction Arbitration

Construction arbitration is the usual forum for large or complex disputes that negotiation or adjudication cannot settle. Parties can appoint arbitrators with construction or engineering experience, the proceedings are private, and an award is final and binding with limited grounds of challenge. Under the New York Convention, Singapore awards can be enforced in over 160 countries.

Arbitration in Singapore is commonly administered by SIAC. In 2025, construction, infrastructure and engineering accounted for 82 of SIAC’s 886 new cases, about 9%.

The SIAC Rules 2025 took effect on 1 January 2025 and include a Streamlined Procedure under which cases are concluded within three months of the tribunal being constituted. That procedure is available for qualifying cases only.

6. Construction Litigation

Construction litigation takes place in the Singapore courts, and hearings are generally public. The courts also enforce adjudication determinations, hear applications to set them aside and support arbitrations. Litigation is more likely where the contract has no arbitration clause, where court remedies such as injunctions are needed, or where several parties are involved.

Alternative Disputes Resolution (ADR) Process in Construction

The ADR process in construction groups the methods above that resolve disputes without a full court trial. They are often chosen because they can be faster, can draw on technical expertise and can run while the project continues.

Durations and costs are indicative and vary with the size and complexity of the dispute. Parties often combine these methods in a tiered clause that escalates from negotiation to mediation, adjudication and then arbitration.

Common Causes of Construction Disputes

SCAL has noted that the most common construction disputes relate to payment, defects and liquidated damages. Scope changes and delays sit behind many of them.

Payment Disputes

Late payment, short payment and disagreements over the value of work done are common triggers, particularly between main contractors and subcontractors.

Variations and Scope Changes

Work added or changed without clear instructions or agreed pricing often leads to disputes over entitlement and cost.

Delay and Liquidated Damages

Disagreements over who caused a delay, extension of time claims and liquidated damages deductions frequently overlap with payment claims.

Defects and Workmanship

Parties dispute whether work is defective, who must rectify it and how much can be set off or retained.

Claims Management Process

Disputes are cheaper to resolve when they are caught early. A sound claims management process starts with contemporaneous records, meaning documents created at the time of events, such as site instructions, variation orders, daily reports, meeting minutes and contractual notices.

Records made at the time carry more weight than accounts reconstructed later, and statutory timelines leave little room to assemble evidence once a dispute is live.

Serving notices on time, tracking variations and delay events as they arise, and using the contract’s own escalation steps help stop minor disagreements from becoming formal claims.

Adjudication of Construction Disputes Under SOPA

SOPA has limits: it does not apply to contracts for construction work on residential property that does not require BCA approval. Strict timelines apply at every stage, and the High Court has set aside a determination where the application was lodged too early. The stages below show the sequence.

After the Determination

Once an adjudicator issues a determination, the following points apply:

• The adjudicated amount must be paid by the due date in the determination.
• If the respondent does not pay, the claimant can seek leave to enforce the determination as a court judgment under section 27 of SOPA.
• A party challenging the determination or the enforcement judgment must pay the unpaid adjudicated amount into court as security. In Lim Kim Huat Building Construction Pte Ltd v LBD Engineering Pte Ltd [2026] SGHC 28, the High Court dismissed the defendant’s application, noting that this security had not been paid.
• Where an adjudicated sum remains unpaid, the claimant may have a statutory right to suspend work under section 26 of SOPA.
• The determination does not end the dispute, as the underlying rights can still be decided in arbitration or court.

Payment Dispute Resolution

Contractors and subcontractors facing non-payment can protect their position in stages. Because SOPA deadlines are short, the early steps matter most.

Secure the Claim

• Serve a compliant payment claim and keep proof of the date of service, since disputes over deemed service have led to determinations being set aside.
• Diarise the payment response deadline and the 7-day dispute settlement period.

Escalate Early

• Run negotiation or mediation in parallel if both sides are willing, without letting the adjudication window lapse.
• Lodge the adjudication application within 7 days after the entitlement arises, and not before.

Enforce and Protect Your Position

• Enforce an unpaid determination as a judgment under section 27.
• Treat suspension of work as a last resort, exercised strictly under section 26 and the contract, because a wrongful suspension can expose the contractor to delay claims.

Arbitration Clause Drafting

A dispute resolution agreement is easiest to settle before the project starts. Vague or inconsistent clauses can create separate disputes about jurisdiction before the real dispute is even heard. Institutions such as SMC publish model clauses that can be adapted to the project.

A well-drafted arbitration clause should cover:

• Dispute board: whether the SIDP applies on a large infrastructure project.
• Seat: the legal place of arbitration, which determines the supervisory court.
• Governing law: the law that governs the contract.
• Institution and rules: for example, administration by SIAC under the SIAC Rules.
• Tribunal: the number of arbitrators and how they are appointed.
• Language: the language of the proceedings.
• Escalation steps: negotiation, mediation and adjudication stages with clear time limits.

When to Involve a Construction Dispute Lawyer

Early advice usually costs less than late advice. A lawyer can review the dispute resolution agreement before you sign, check that payment claims and notices comply with SOPA and the contract, and assess whether mediation, adjudication or arbitration suits the dispute. Because SOPA windows are measured in days, a delay can cost you a right.

Legal input is especially valuable when the claim is large, when the contract has a tiered or bespoke dispute clause, when a determination is being enforced or challenged, or when the matter may proceed to arbitration or court.
