Pacific Association of Quantity Surveyors Young QS Group (PAQS YQSG) visit to SoilBuild ICPH organized by Singapore Institute of Surveyors and Valuers (SISV) in September 2022. ● ● ● Upon completion of the PPVC carcass: 30% Upon completion of the off-site fit-out: 30% Final installation on site: 40% Similarly, an Advance Payment Guarantee from the Contractor remains as a condition precedent prior to any milestone payment to be made by the Employer. Insurances Due to some off-site PPVC works to be carried out in oversea factories, the existing off-site storage and inland transit endorsement that have territorial limits in Contractor’s All Risks Policy (CAR) are no longer sufficient. Additional Property All Risk Policy is required to cover off-site fabrication in another country. A proper Marine Cargo Insurance is also required to cover shipments or transit of the PPVC modules from another country to Singapore. Both insurance policies are to be issued in the joint names of both the Contractor and Employer so long the PPVC modules are stored overseas. As such, it is preferable for the Contractor to directly procure the insurance from the Employer’s insurance broker in ensuring the Employer’s full overseas insurance coverage is being well taken care of. Nominated Sub-Contracts (NSCs) With the adoption of the PPVC, some of the NSCs’ products such as sanitary wares, wardrobes and switches shall be delivered to off-site fit-out yards instead of the construction site. Back-to-back provisions relating to payment, advance payment guarantee and insurances shall be provided and stipulated clearly in the NSC’s contract to ensure the water-tightnesses of the overall contract provision between the Main Contract and NSCs. Government Support Measure for PPVC during pandemic period As a result of the COVID impact BCA has granted waivers to relax the minimum required level stipulated in the COP 2017 on the finishing and fittings to be completed off-site for the PPVC modules. One example is allowing full cabinetry works to be done on site instead of only restricted to door installation. The Government has also further supported SoilBuild in providing a Temporary Occupational Land (TOL) at Punggol Pulau Timor as a temporary manufacturing and storage space for their precast components including PPVC modules. The bulky and heavy PPVC modules are unable to be stored on site and hence, Just in Time (JIT) delivery and installation are crucial for the smooth construction site progress. The TOL space at Punggol Pulau Timor serves as an in-time aid to SoilBuild in resolving the PPVC modules’ storage issue. Innovation To Improve PPVC Design SoilBuild highlighted that the cost premium of adopting PPVC has reverted back to the initial level of 15% during the pandemic period. The COVID pandemic situation has further triggered the PPVC manufacturers to be innovative on how to improve PPVC 00:0 8
