Prestressed buildings offer various advantages as compared to the conventional reinforced concrete design, including lighter structural weight, better crack resistance and more cost effectiveness. Prestress design with post-tensioning has been commonly adopted for cast in-situ building structures in Singapore due to the above advantageous.

This training course explains the design fundamental of the prestressed structures with post-tensioning. During the course, the structural behaviour of prestressed buildings and their benefits as compared to the conventional reinforced concrete are highlighted. The economical range with reference to the span length/ column grids for prestressed concrete structures are studied during the course

In the second part, the course explains the steps of designing a post-tensioned structure. This starts with the initial member sizing which maybe useful for architect and engineer to make provisions for sufficient floor-to-floor headroom. This is followed by the structural analysis of the prestressed structure, and the design of the tendon prestressing force at service state as well as the ultimate capacity of the prestressed structure at ultimate state.

This course also explains the rules and design requirements for tendon and steel reinforcement detailing for prestressed flat slabs, as well as how tendon elongation is used to monitor the QA/QC works for post-tensioned structures at site.

CV of Speaker

Ir. Dr. Low Hin Foo graduated from Monash University, Malaysia with a PhD(Structure). He graduated from University Malaya with an Honours degree in Civil Engineering.  Since then he has almost 20 years of design and construction experience in various types of bridges, as well as prestressed building structures both locally and abroad. He was the Technical Manager for prestressing specialist contractor, BBR Construction Systems (M) Sdn Bhd; and he is currently the Principal Engineer of a bridge consultancy firm in Singapore, OS Alliance Pte Ltd, and the Group Managing Director of OSD Consultants Group in Malaysia.

Ir. Dr. Low has vast experience in the design and construction of long span bridges using precast and cast in-situ prestressed segmental box girder (SBG) and he is familiar with the design of integral bridge with prestressed girders made continuous. Besides, he has huge design experience in the design of prestressed structures for large commercial projects and high-rise towers, particularly in handling the design of prestressed flat slab or flat plate systems with irregular column grids, including prestressed transfer plate and raft foundation as well as their lateral response with columns of high-rise buildings.

Chemical Hazard Management at Worksite (Safety, 4 Hours)

 Course Objective

This module aims to inculcate effective hazardous chemical management at worksites through lectures, interactive sharing, and group discussions. The module will increase awareness of how a well-designed and implemented hazardous chemical management program can effectively manage chemical risks associated with myriad of chemicals at worksites, enabling participants to better manage worksite chemical safety.

 Course Outline

• Legislative Requirements for Managing Hazardous Chemicals at Worksites
• Understanding Chemical Hazards, Safety Data Sheets, Chemical Risks
• Developing Chemical Risk Register, Safe Work Procedure
• Control of Chemical Safety Related Works & Documentation
