Construction and Project Management
6.1 Location of The Project and Adjacent Areas
• The condition of the roads surrounding the project must be able to accommodate the weight and size of the PPVC module delivery.
6.2 Access and Traffic Management for Trailers with Heavy Cargo
• The access to and within the site must be able to accommodate trailers with heavy cargo. Slopes and undulating terrain might prove to be a challenge for heavy vehicles. The turning radiuses of the trailers has to be considered during the planning stage of the site to avoid choking of vehicle access.
• Trailers with heavy cargo pose potential hazards upon entering while navigating the site. Traffic controller has to be employed to ensure smooth traffic management within the site.
6.3 Consideration of Just-In-Time (JIT) Operation
• Unlike conventional precast, PPVC modules are unable to be stored on site. Therefore, a Just in Time (JIT) installation could prove to be efficient and productive. The rate of installation has to be determined for a smoother JIT operation.
• Precast supplier can further employ systems such as Traffic Monitoring and GPS for Prime Movers to better facilitate deliveries. This will in turn make JIT operation smoother and more predictable.
• It is advisable to have space for unloading and storage in the event where JIT installation is not possible, e.g. during inclement weather, etc.
6.4 Types of Cranes
• The crane employed must be able to handle the weight of the PPVC modules, but at the same time be able to provide enough coverage for the intended block.
• Contractors shall seek approval from the relevant authorities on the maximum allowable AMSL clearance for erection of cranes.
A comprehensive risk assessment shall be established to identify all potential hazards. Appropriate control measures must then be set up, communicated and implemented before the commencement of works.
