Nanyang Technological University (NTU) is a global leader in sustainability research, attracting more than S$1.2b in research funding, as well as applying the principles of sustainability in the design of its lush, green campus.
Our team is providing accredited checker (AC) services for the proposed 27m tall sports hall building with 72m span arch roof. Situated on a 200ha site, the hall will be a valuable amenity for the university students, providing facilities for badminton, volleyball, basketball and other activities.
With an area of 10,000m2, the three-storey building will accommodate 1,000 spectators, effectively doubling the current seating capacity. The mechanized seats will be retractable, so that the venue can be configured into 13 full-sized badminton courts or into three basketball or volleyball courts and a netball court.
Sustainability in practice
In line with NTU’s intention to achieve a 35% reduction in energy and water consumption as well as waste production by 2020, the new sports hall incorporates many sustainable features including use of environment-friendly materials and energy efficiency and water efficiency measures.
The sports hall will be the first large-scale building in Singapore to use a sustainable Engineering Wood System (EWS). An EWS is created through binding layers of timber using structural adhesives to produce solid plane timber suitable for roofs, floors or walls.
The superstructure will be an EWS that sits on a normal reinforced concrete substructure. Two forms of EWS will be used. Glulam (glued laminated timber with panels linearly aligned) will be used for beams, columns and the long span roof support, and prefabricated cross-laminated timber (CLT) will be used for internal finishes and flooring. The super-structure, including the 72m span arch roof, will feature both the EWS component and structural steel.
EWS is produced from sustainably-managed forests, possesses the least carbon footprint among building materials, reduces overall cooling costs during its lifecycle and can be recycled upon demolition. EWS has the potential to reduce on-site labour, programme duration, the need to deliver materials to work sites and inconveniences to neighbours. The lighter construction of an EWS, compared to concrete, also reduces the need for heavy foundations.
The project commenced August 2014 and is currently under construction.
