Working above an MRT tunnel to deliver flats: Why this S’pore builder earned accolades for its first BTO project

Vico Construction achieved a significant milestone by winning the Housing Board's 2026 Certificate of Merit in construction for its first build-to-order (BTO) Housing Development Board project, Tampines GreenOpal. The MRT tunnel beneath the development posed a major challenge, as the construction team had to work around existing underground utilities.

The pandemic also caused a manpower shortage, which threatened to delay the foundation works. However, Vico managed to overcome these obstacles and delivered the project on schedule. The construction team utilized precast construction techniques to save about 700 man-days at the site. Additionally, Vico tackled the issue of fabricating rebar cages by training its own workers to produce about 30% of the required components, saving three months of work.

The company also adopted Building Information Modelling, which allowed for early identification of potential problems and reduced the need for rework. QR codes were employed to track precast components from production to installation, enabling the timely resolution of any issues. Vico prioritized safety, achieving 5.4 million accident-free man-hours during the project, with a workforce of around 500 to 600 people at its peak.

The workers participated in daily toolbox meetings to discuss daily risks and protective equipment requirements, while regular meetings with subcontractors addressed site safety concerns. With this achievement, Vico Construction is poised to continue exploring innovative construction methods that enhance safety, efficiency, and reduce reliance on manpower.
