SUSTAINABILITY POLICY SUSTAINABLE SOLUTIONS Sustainable Solutions Design with PT offers significant savings Save natural resources during construction Enhance durability during the life cycle SUSTAINABLE ACTIONS Have you read it ? MORE+ Video Creating solutions together VSL's corporate movie → WATCH MORE + Optimise design with reusable equipment Contributions to sustainable construction and to more environmentally-friendly execution of work have been part of the VSL Technical centres’ objectives for a long time. The main scope of engineering works covers – among other aspects – the design and detailing of major erection equipment such as launching gantries, lifting frames, and form travellers. VSL’s Technical centres assist other parts of VSL around the world in saving thousands of tonnes of steel in new fabrication of erection equipment through optimized design and, in particular, the reuse of existing equipment. A single gantry has erected about 2,700 segments on four projects. It proved to be a sound investment for VSL Malaysia to take back the Second Link gantry used on the Mekong River crossing after two years duty on the Pakse Bridge in Laos. The gantry was immediately reused for the Bayan Baru Viaduct, followed by the Subang Kelana Link Project in Kuala Lumpur. Reuse of the erection gantry saved an estimated 1,100t in new steel fabrication for the last three projects. MORE+ Increased structural stability of buildings Using VSL R-dampers combined with post-tensioned floors makes the whole structure -from the foundations to the top -lighter than traditional methods, while providing a more ductile and resilient structure for the control of vibrations. With its optimised design, the VSL R-damper works effectively in dissipating energy in structures subject to vibrations arising from any external source, such as pedestrians walking on a floor, cars on a bridge, wind or earthquake. The damper dissipates part of the energy input while the structure itself only has to cater for the balance of the total forces generated by the vibrations. Damper stiffness and location need to be well matched to the structure displacements for optimum performance and efficiency. Installing the dampers allows the engineers to design the structure for lesser effects, resulting in reduced element sizes in the lateral load-resisting members and the most effective use of the materials required for construction. Use of post-tensioned floors provides a further reduction in the total weight of the superstructure, and consequently in the base shear and over-turning moment. This means that the foundations are reduced as well. The VSL R-dampers require only limited maintenance due to their simplicity and very high durability. All these benefits lead to significant cost savings and, more importantly, the dampers contribute to safer structures at lower overall cost.
