ไทยAIR QUALITY MANAGEMENT
The Company recognizes the importance of effectively managing, preventing, and mitigating impacts arising from emissions and waste generated within construction project areas. As a provider of construction services, construction consultancy, and building renovation services, the Company, through its construction management and supervision units, strictly complies with prescribed environmental prevention and mitigation measures in accordance with relevant regulations to minimize impacts from pollutants and waste such as dust (TSP), air pollutants including Carbon Monoxide (CO), Sulfur Dioxide (SO₂), Nitrogen Dioxide (NO₂), and noise pollution to the lowest practicable level. The Company implements measures including water spraying within construction areas and on access roads, washing truck wheels before exiting construction sites, ensuring machinery and equipment are maintained in proper working condition to prevent excessive noise disturbances, scheduling working hours to avoid disruption to nearby communities, treating wastewater generated on site to meet regulatory standards prior to discharge, and managing waste in accordance with the 3Rs principles (Reduce, Reuse, Recycle) before transferring it to licensed external parties for proper disposal.
The Company regularly monitors air quality and noise levels arising from construction activities by measuring concentrations of TSP, CO, SO₂, NO₂, maximum noise levels, and 24-hour average noise levels. Monitoring is conducted both within construction sites and in surrounding communities or sensitive areas.
This monitoring ensures the effectiveness of environmental prevention and mitigation measures and enables continuous oversight of potential impacts on construction workers and residents in nearby communities or sensitive areas.
Not exceeding the standards prescribed by the National Environment Board Notification
Pollution Management Implementation Approach
The Company has established the following measures to reduce air pollutant emissions.
In controlling and reducing air emissions, the construction supervision consultancy function provides clear recommendations and requirements for contractors, including:
- Utilizing machinery that meets Euro 4 standards or higher to reduce CO₂ and NOx emissions.
- Applying dust suppressants or conducting water spraying every two hours to reduce dust from excavation and transportation activities.
- Requiring trucks to be covered with tarpaulins to prevent dust dispersion during transportation.
- Planning the shortest transportation routes and avoiding congested traffic areas to reduce CO₂ emissions from travel.
- Selecting construction materials produced through low-carbon processes, such as concrete incorporating recycled materials or blended cement.
Monitoring and controlling air emission reduction performance is an integral part of construction supervision consultancy services. The Company conducts monitoring on a quarterly basis at construction sites, with the following procedures:
- Monitoring monthly fuel consumption of machinery and vehicles and comparing results against established Goals.
- Periodically measuring air quality within and around construction sites and reporting results to relevant stakeholders.
- Reporting CO₂ emissions and dust levels from construction sites on a quarterly basis in project sustainability reports.
Inspecting and maintaining machinery and vehicles in accordance with scheduled maintenance plans to minimize pollutant emissions.
