Highlights of Construction Management
• Achieving 3 days cycle for structural work:
The tower consists of more than 160 floors & to be completed within a very tight schedule Hence, the following key construction technologies were incorporated to achieve the 3-day cycle set for the concrete works:
• Auto Climbing formwork system (ACS).• Rebar pre-fabrication.• High performance concrete suitable for providing high strength, high durability
requirement, high modulus, and pumping.• Advanced concrete pumping technology (BSA-14000 SHP-D).• Simple drop head formwork system that can be dismantled and assembled
quickly with minimum labor requirement.• Column/Wall proceeding method, part of ACS formwork system.
• Optimum Transportation:
They developed an optimum transportation systems with large capacity high speed equipments to carry raw material and pre-fabricated components.
• Management of Labour:
They managed to get sufficient cheap labour from South-Asian countries like INDIA, PAKISTAN, BANGLADESH, SRILANKA etc.
