Termination of a construction contract is one of the most high-stakes decisions an employer or contract administrator can make. Under Singapore’s Public Sector Standard Conditions of Contract (PSSCOC), an employer possesses powerful contractual remedies when facing a contractor in default—such as taking over the physical site, engaging new contractors to complete the works, and enforcing financial security through a performance bond.
However, these rights must be exercised with extreme caution. Initiating termination without strict adherence to both substantive contractual grounds and mandatory procedural timelines can expose the employer to claims of wrongful repudiation, transforming an underperforming project into an incredibly expensive legal and financial disaster.
Identifying Valid Grounds for Contractor Default
A project suffering from delays, minor workmanship defects, or cash-flow constraints does not automatically grant the employer a general licence to terminate. Under Clause 31.1 of the PSSCOC, the contractual right to terminate for default is strictly restricted to defined grounds, which include:
- Abandonment: The contractor completely walks away from or abandons the project.
- Failure to Commence: Failure to start physical works on-site without a reasonable cause.
- Lack of Diligence: A persistent failure to proceed with due diligence, speed, or expedition.
- Defective Workmanship: A persistent failure to rectify rejected or non-compliant work.
- Subcontracting or Instruction Breaches: Specific material breaches involving unauthorised subcontracting or failing to comply with formal contractual instructions.
Before taking action, the employer must establish that the contractor’s behavior has clearly satisfied these defined contractual defaults, rather than treating general performance issues as a license to end the contract.
Navigating the Strict PSSCOC Procedural Mechanism
In Singapore construction law, procedural non-compliance can invalidate a termination, turning the employer’s action into a repudiatory breach of contract. Employers must follow the PSSCOC mechanism with absolute precision:

Certification of Default: The process typically begins with the Superintending Officer (SO) issuing a Termination Certificate formally certifying the contractor’s specific default.
Cure Notice / Remedial Opportunity: Depending on the nature of the default, the contractor may be contractually entitled to a formal notice and a specific period to rectify the default before the employment is officially ended.
Written Termination Notice: If the contractor fails to remedy the breach within the prescribed period, the employer may then issue a formal written notice ending the contractor’s employment.
Any error in notice timing, delivery method, or content can completely undermine the process and expose the employer to immense liability.

Step-In Rights and Site Takeover Realities
Once a contractor is removed from a project, the immediate priority shifts to maintaining project continuity. Clause 31.2 of the PSSCOC grants the employer powerful step-in rights to take control of the physical site.
Under this clause, the employer or their newly appointed completion contractor may:
- Take over and utilize construction equipment, plant, temporary works, tools, goods, and unfixed materials left on-site to complete the works.
- Assert a lien over those site items, with the right to sell them and apply the proceeds toward outstanding completion costs or damages.
While these rights provide a vital mechanism to keep the project moving, exercising them requires extensive operational preparation. Project teams must rapidly coordinate new labour, establish site security, verify the condition of left-behind equipment, and secure critical project documentation.
Performance Bonds Are Not an Automatic Shortcut
A performance bond—typically provided as a bank or insurer guarantee under PSSCOC security deposit rules—is a crucial tool for financial security, but calling it is not an automatic consequence of termination.
The landmark Singapore High Court decision, SH Design & Build Pte Ltd v Jurong Port Pte Ltd SGHC 159, serves as a vital warning for employers. In this case, the court restrained a call on a performance bond because the underlying demand was found to be unsupported by the contract’s requirements due to an allegedly invalid determination by the Superintending Officer.
The critical takeaway is that termination, default certification, and security enforcement are connected but legally distinct steps. An employer cannot simply assume a bond will be paid out automatically upon termination; the call itself must strictly satisfy all contractual and legal pre-conditions.
Six Critical Pitfalls to Avoid Before “Pulling the Plug”
To protect project budgets and minimize dispute risks under PSSCOC, contract administrators must avoid these common administrative traps:
- ⚠️ Terminating Too Quickly: Prematurely ending a contract before the contractor’s performance has contractually crossed the high default threshold of Clause 31.1.
- 📝 Relying on Verbal Complaints: Issuing termination notices based on undocumented site arguments. All default claims must be backed by a flawless trail of written instructions, site diaries, photographs, and formal correspondence.
- ⏰ Ignoring Contractual Notice Timelines: Failing to calculate notice periods, delivery methods, or cure periods with absolute precision.
- 🏦 Treating the Bond as a Guaranteed Cure-All: Making a premature or non-compliant call on the performance bond, which can lead to immediate court injunctions.
- 💸 Underestimating Financial Consequences: Overlooking the fact that termination frequently inflates final completion costs, triggers subcontractor claims, and delays handover.
- 🔧 Failing to Plan the Post-Termination Takeover: Removing the contractor without having a practical plan for immediate site security, utility management, and the remobilization of new completion contractors.
Conclusion
Ultimately, contract termination is as much a strategic project-continuity decision as it is a legal one. While the PSSCOC provides a clear commercial framework for managing contractor default, its mechanisms must be administered with absolute discipline. By systematically establishing the contractual basis for default, adhering to strict notice procedures, preserving a meticulous contemporaneous record, and planning for the physical site takeover, employers can successfully navigate contractor defaults and protect their capital investments.
FAQ
What constitutes contractor default?
Answer: Contractor default may include abandonment, failure to commence works, failure to proceed with due diligence, persistent failure to rectify rejected work or other specified contractual breaches.
What are step-in rights?
Answer: Step-in rights allow an employer, where the contract permits, to take measures to continue the project after a contractor’s failure, including appointing another contractor and using certain site resources.
Can an employer automatically call a performance bond after termination?
Answer: Not necessarily. A performance bond has its own contractual terms and conditions. The circumstances surrounding the underlying default, contractual determinations and the wording of the bond may all be relevant.
Does PSSCOC apply outside Singapore?
Answer: The PSSCOC is designed for Singapore public-sector construction projects. However, the contractual principles surrounding termination, contractor default, project takeover and performance security have broader relevance to construction contracts internationally.
Why is documentation important before termination?
Answer: Documentation can establish the history of the contractor default, demonstrate that contractual procedures were followed and provide evidence if the termination is later challenged.
