Noises

 

During construction activities, we prioritize the use of low-noise machinery, equipment, vehicles, and tools, complemented by rigorous noise assessments and control measures. For operations with the potential to generate high noise levels, comprehensive scheduling and construction planning are implemented to minimize disturbances to surrounding communities. In cases where construction noise may trigger public concern or complaints, the company proactively engages in stakeholder communication and formulates mitigation plans to ensure timely response to community issues. All complaints from the community are received through multiple accessible channels, including verbal and written submissions, and are addressed promptly. We are committed to maintaining transparency and efficiency throughout the resolution process.
 

-   Adopt low-noise construction machines, equipment, and vehicles as a priority.
  • -   Adjust our construction methods or complete operations that can create significant noise in a prefabricated factory and then transfer them to the site. Where the high-noise issue cannot be eliminated or avoided, it is a must to install sound insulation or adopt anti-vibration measures as required.
  • -   Avoid working during early morning or at night.

 Water Resources Management

In alignment with the principles of sustainable development, Acter is committed to the responsible use and conservation of water resources. The Company conducts an annual internal review of water usage at its headquarters and establishes water reduction targets to minimize environmental impact. The headquarters building is supplied exclusively by the Taiwan Water Corporation, with no use of groundwater or alternative water sources. Water is primarily used by employees and visitors, and domestic wastewater is discharged into the municipal sewage system, posing no significant impact on the natural environment. To enhance water conservation awareness among employees, Acter has installed automatic sensor faucets, placed water-saving reminders, and regularly distributed environmental e-newsletters. On construction sites, wastewater is managed in accordance with its classification and treated using appropriate methods to ensure regulatory compliance and minimize pollution. Prior to the commencement of construction, Acter develops detailed water use plans and enforces strict environmental monitoring throughout the project lifecycle. Licensed contractors are engaged to handle wastewater collection and treatment. Furthermore, for construction activities that may pose a risk to groundwater quality, preventive measures are taken—such as installing impermeable barriers and monitoring systems—to safeguard groundwater resources from contamination.

 Nature and Biodiversity

 

“Biodiversity loss” has emerged as one of the most critical global environmental challenges in recent years. Acter’s major operational sites, including its headquarters and global project sites, are not located within legally protected habitats or areas of high biodiversity value that are significant to indigenous peoples or local communities.
To proactively respond to the Global Goal for Nature, Acter incorporates ecological assessments and monitoring throughout all phases of engineering projects, including design and construction. Based on project characteristics and local environmental conditions, Acter develops corresponding ecological management measures to minimize the potential environmental impacts arising from its operational activities.

Acter will continue to monitor international trends and emerging environmental issues, integrate ecological conservation and nature-related risks into its overall risk management framework, and regularly assess the potential impacts of its operations on the environment. Through collaboration with key value chain partners, Acter remains committed to jointly protecting natural ecosystems and promoting sustainable coexistence with nature.
