Client: Nanyang Technological University of Singapore
Project Brief: Proposed Erection of 1 Block of 11-Sty & 3 Block of 13-Sty Student Hostel Development & 1 Block of 4-Sty MSCP with Ancillary Facilities
Project Highlights: 3rd PPVC project in Singapore and 2nd largest in 2015. Up to 25% Manpower Reduction & 40% improvement in Productivity. Redesign of Structure to PPVC Modules. Green Mark Project
Project Duration: Jun 2015 to Jun 2017
Location: Nanyang Crescent, Singapore
- Project was converted to a design and build contract where Zheng Keng, together with the team of consultants have to re-design the development from conventional reinforced concrete structure to a modular system for PPVC.
- Tight timeline of 20 months to complete the re-design, re-submission to authorities and construction.
- Good management skills required to coordinate client’s, consultants’ and sub-contractors’ inputs and consensus on final PPVC design was obtained within five months. Design cannot be changed upon manufacturing of the PPVC modules.
- Crucial to strike a balance between the PPVC modules’ hoisting/installation efficiency and the cost of site operations. Increasing the crane numbers and capacity increases efficiency but also operation cost.
- Importing of PPVC modules from China presented logistical challenges. Factors like shipping costs and fitting yard capacity affect the selection of a suitable module size.
- Proper manpower planning and scheduling required in order to complete project on time as the PPVC production and installation took place in three different locations (overseas, local fitting yard and actual site).
- Special arrangements required for ITA & REs/RTOs to inspect the PPVC structure periodically at the production factory in China before delivery to site.
