CDL is committed to comply with all applicable EHS legal requirements enforced by local authorities such as BCA, NEA, MOM and SCDF. Through constant monitoring, evaluation, and auditing of our ISO14001 and OHSAS18001 certified EHS management system, CDL actively ensures that all our activities and operations comply with existing regulatory requirements.
Managing Waste Water Discharge at Construction Sites
CDL works with all our contractors in implementing earth control measures (ECM) at construction sites to prevent silt from polluting our waterways. We ensure the Total Suspended Solids (TSS) readings of the discharged water do not exceed the legal limit of 50 mg/litre. Beyond this, we also set targets below the legal limit for our ongoing projects. For example, in one of our recently awarded projects, we set a target of less than 40 mg/litre on the TSS reading of the effluent, highlighting our commitment to preventing pollution.
In 2017, the highest TSS level discharged across all our nine worksites was 19 mg/ litre, well below the legal limit.
Managing Construction Noise
In Singapore, NEA regulates the noise levels from construction sites with a set of permissible noise limits that vary depending on the time of the day and neighbouring premises. To protect nearby residents, we place emphasis on our builders to comply with the construction noise limits at all our construction sites.
To minimise noise-related complaints, our builders are encouraged to put in place an active management programme and to take all necessary action to address and resolve related complaints. As part of our efforts to keep the community informed about project statuses, schedules of the construction process at each site are communicated with a view to inform the community about works that might affect them.
Incidents of Non-compliance
In 2017, four fines were imposed on our builders across nine construction sites. Two were for vector breeding and two for performing construction activities above the noise limit. At our managed properties, two fines were imposed for vector breeding.
To prevent future occurrences of noncompliance, we have reviewed and streamlined our current processes to improve and tighten our EHS practices.
Since 2005, we have been incentivising our builders to uphold high EHS standards through the CDL 5-Star EHS Awards and monetary rewards. From 2013, a penalty system has been imposed on builders of all new developments for any EHS infringements. This was formulated as part of an ongoing review of our system and process to maintain good EHS performance.
As a responsible corporate citizen, we provide avenues for the public to make enquiries or complaints on environmentrelated matters. Phone hotlines managed by our appointed builders are set-up at all construction sites. In 2017, across our nine ongoing sites, we had no complaints regarding dust from construction activities affecting nearby residents.
