A Practical Guide to Progress Payment Claims Under Singapore SOP Act (BCISPA)

Cash flow is the lifeblood of every construction enterprise. Singapore’s Building and Construction Industry Security of Payment Act (SOP Act / BCISPA) establishes a fast-track statutory framework to protect progress payments across main contracts and subcontracts.

Key Statutory Requirements for a Valid Payment Claim

To preserve statutory adjudication rights, each monthly progress payment claim must be served strictly within the contractual or statutory reference period, clearly state the claimed amount, and provide sufficient breakdown and measurement substantiation for the respondent to assess the work completed and materials delivered to site.

Why Meticulous Documentation Wins Valuations
