COVER STORY A key requirement of the Arup RSS team was the reporting of safety risks on site. This was proactively undertaken by the RE team, ably supported by the RTO team, who highlighted issues to Dragages on a prompt and cooperative basis. In the positive spirit of the project, Dragages was proactive in addressing concerns raised by the RSS team, which contributed to the outstanding safety record of the Singapore Sports Hub project. The Arup team was committed to a high standard of safety, as demonstrated by the involvement of the QPs, QP Supervisors and Project Manager in fortnightly meetings with the RSS team to highlight any accidents, suspected foul play and non-compliance. In a systematic manner, minutes of the meetings were taken and circulated, and lists of non-conformance issues were monitored via an elaborate schedule.
PUBLIC SAFETY ENSURING SAFETY AND A CLEAN ENVIRONMENT As the construction of the Singapore Sports Hub was carried out at a site in close proximity to an operational MRT and the Kallang Basin, safety was of paramount importance to the management of the construction. Approval was obtained from the Land Transport Authority (LTA) for the safe operation of all fixed and
mobile cranes within the rail corridor. Standing supervision was put in place for all cranes lifting over the MRT first reserve. Continuous automated monitoring systems were installed in the MRT station and tunnels to monitor any impact from the construction, with negligible movements observed. Close communication with authorities To ensure the life safety of workers, close consultations were held with the Ministry of Manpower (MOM) and LTA, to assess the risks on site and best practices, to prevent incidents. A comprehensive health, safety and environmental risk register, which included a range of preventive measures that can be taken, was also established and made available to site staff so that they would be made aware. All ‘close calls’ were registered, and accidents, investigated by Safety Officers, many of whom were of senior rank. Arup also took part in regular site safety meetings with Dragages. STRUCTURAL SYSTEMS WITH MINIMAL IMPACT ON NEIGHBOURHOOD Protecting the Kallang Basin The Singapore Sports Hub site has a long interface with the freshwater Kallang Basin. It was of vital importance to minimse any disruption to the quality of water and existing
water edge assets. Acknowledging this, the design deliberately avoided impacting on the existing seawall by keeping all structures separate. This meant that the basin was not disrupted by the construction work along the water edge. All images by Arup, unless otherwise stated.
