CDL is dedicated to minimising and mitigating the impact of our developments on the environment and the surrounding communities. We are also committed to complying with all applicable EHS legal requirements enforced by local authorities, such as the BCA, NEA, PUB, MOM and SCDF. Through constant monitoring, evaluation, and auditing of our ISO 14001 and OHSAS 18001 certified EHS Management System, 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. CDL works closely with all our contractors to track the quality of water discharged to public sewerage and drainage systems and to ensure that Total Dissolved Solids 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 . At all our construction sites, Earth Control Measures are implemented to prevent silt from polluting our waterways.

In the incidence of exceeded TSS readings, prompt corrective actions such as lean concreting were taken to rectify the issue. CDL will continue to work with contractors to increase vigilance in the management of water discharge.

Managing Vector Control at Construction Sites

To keep incidence of vector-borne diseases low, NEA has effective vector management systems, complemented by education, enforcement, and continuous research in place to achieve this goal. Recognising that construction sites, if not well-managed, could become environments for mosquito breeding and rodent infestation, CDL works closely with our builders to ensure that effective systems are in place to prevent pests, curb dengue transmission, and protect workers and residents around our work sites against dengue fever.

In addition to ensuring that our builders schedule and conduct regular housekeeping on-site, we also require that they maintain comprehensive pest surveillance and control programmes. We also 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 Impacts on Communities

In construction and development, residents who live in the immediate vicinity of a construction site are considered key stakeholders, and we understand that building activities at construction sites might pose some inconvenience to this community. As a responsible corporate citizen, we provide avenues for the public to raise enquiries or complaints on EHS-related matters. Phone hotlines managed by our appointed builders are set-up and made publicly available at all construction sites. Prior to the start of key construction stages, our builders conduct surveys where feedback is collected, compiled and analysed, and concerns are addressed. As an avenue for further feedback, contact details are publicly displayed on banners around the construction site, alongside other information required by local regulations.

Since 2014, CDL has implemented a public communications plan for communities located within a 100-metre radius of our developments undergoing construction or asset enhancement in Singapore. As part of efforts to keep the local community inform ed, flyers containing project details and the construction schedule are distributed. Measures to reduce the impact of construction work on the surroundings also continue to be a priority. In 2019, we received two complaints across our seven ongoing sites regarding dust from construction activities affecting nearby residents. The contractor has since put in controls in the area surrounding the construction site to prevent further incidences of dust nuisance to the community.

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 implement an active management programme and to take all necessary action to address related complaints. As part of our efforts to keep the community informed about construction status, schedules of the progress at each site are communicated to prepare the community about upcoming works that may affect them.
