MINIMISING ENVIRONMENTAL IMPACT ON OUR COMMUNITIES
The Company is dedicated to mitigating the negative impact of our developments. 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 and the Singapore Civil Defence Force. Through constant monitoring, evaluation, and auditing of our ISO 14001 and ISO 45001-certified EHS management systems, the Company 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. The Company works closely with all our contractors to track the quality of water discharged into public sewage and drainage systems 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 respectively.1 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. The Company will continue to work with contractors to manage water discharge.
| 2021 | 2022 | 2023 | 2024 | 2025 | |
| Highest TSS (mg/litre) | 40 | 31 | 32 | 18 | 19 |
Managing Vector and Pest Control at Construction Sites
Construction sites are potential environments for mosquito breeding and rodent infestation. As such, the Company works closely with our main contractors to ensure that effective systems are in place to prevent pests and curb dengue transmission 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. Apart from 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, senior management site visits and educational talks to ensure effective vector control and minimise incurring fines for vector breeding.
Managing Impact on Communities
The Company provides avenues for the public to raise enquiries or feedback on EHS-related matters. Hotlines managed by our appointed main contractors are made publicly available at all construction sites. Upon receiving EHS-related feedback such as dust or noise disturbance impacting the community, the site management will implement controls in the surrounding area, addressing the feedback to mitigate the likelihood of 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 wellbeing 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 undertake necessary actions to address related complaints. Schedules of the progress at each site are also communicated to the community to apprise them of upcoming works.
Training And Educating Employees On Environmental Management
The Group believes that environmental awareness and training for employees are catalysts for positive change. We have designed sustainability-related training and content covering topics such as the management of energy, water and waste to fulfil the following objectives:
- Build awareness on environmental issues
- Develop shared vision for a sustainable future
- Empower positive actions
In 2025, as part of the Group’s initiative to educate employees on waste management, we delivered content on responsible waste management and disposal techniques for waste generated from our construction sites and managed buildings. This includes sharing on the Company’s annual waste reduction targets, partners and stakeholders that we work with to collect, treat, segregate, and recycle waste.

- A visit to the Biodiversity Training Centre to learn how Singapore’s Land Transport Authority collaborates with contractor to balance tunnel construction with measures to minimise and mitigate environmental impacts
- A visit to City Square Mall to observe how repurposed materials are used for the rejuvenation and revitalisation of the mall
- An interactive workshop enabling employees to address climate challenges and develop group solutions
- Nearly 300 employees attended a Group-wide seminar on green building, decarbonisation and safety, which included segments on waste management
