CDL is dedicated to mitigating the impact of our developments on the environment and surrounding communities. We are also committed to complying with all applicable EHS legal requirements enforced by local authorities, such as BCA, NEA, PUB, the Ministry of Manpower (MOM) and the Singapore Civil Defence Force (SCDF). Through constant monitoring, evaluation and auditing of our ISO 14001 and ISO 45001-certified EHS management systems, CDL actively ensures that all our activities and operations comply with existing regulatory requirements.

Managing Water Discharge at Construction Sites

The discharge of wastewater into the public sewerage system and open drains, canals and rivers are strictly regulated by PUB and NEA. To ensure that Total Dissolved Solids (TDS) and Total Suspended Solids (TSS) readings of the discharged water do not exceed the legal limit of 1,000 mg/litre and 50 mg/litre respectively1, CDL works closely with all our contractors to track the quality of water discharged into public sewerage and drainage systems. At all our construction sites, Earth Control Measures (ECM) are implemented to prevent silt from polluting our waterways. In the incidence of exceeded TSS readings, prompt corrective actions are taken to rectify the issue. CDL will continue to work with contractors to increase vigilance in the management of water discharge.

Managing Vector and Pest Control at Construction Sites

Recognising that construction sites could potentially become environments for mosquito breeding and rodent infestation, CDL works closely with our main contractors to ensure that effective systems are in place to prevent pests and curb dengue transmission amongst workers and residents around our worksites.

The ISO 45001 occupational health and safety management system and CDL 5-Star EHS Assessment provide a risk management framework to identify and mitigate the risks associated with vector and pest control at construction sites. In addition to ensuring that our contractors schedule and conduct regular housekeeping on-site, we require that they maintain comprehensive pest surveillance and control programmes. We actively engage our contractors and their workers through awareness-building and educational talks to ensure effective vector control and minimise incurring fines for vector breeding.

Managing Impact on Communities

We provide avenues for the public to raise enquiries or feedback on EHS-related matters. Hotlines managed by our appointed main contractors are set up and made publicly available at all construction sites. Upon receiving EHS-related feedback such as noise or dust nuisance to the community, the site management will implement controls in the surrounding area to address the feedback and prevent further incidences.

In Singapore, NEA regulates the noise levels from construction sites, with a set of permissible noise limits that vary depending on the time of day and type of neighbouring premises. To protect the well-being of nearby residents, our main contractors must comply with the construction noise limits at all our construction sites. To minimise noise-related complaints, our main contractors are encouraged to implement an active management programme and take all necessary actions to address related complaints. To ensure the community is aware about the construction status, schedules of the progress at each site are communicated to inform the community about upcoming works.
