Performance
Commitment, Challenge and Opportunity
The Company is well aware that air quality is a crucial factor that directly affecting the health and well-being of residents, surrounding communities, and overall environment. The long-term success of real estate business and sustainable urban development cannot be separated from effective air quality management. Therefore, the Company is committed to enhancing measures to control and prevent air pollution at every stage of operations, from building construction and material selection to managing indoor air quality in residential buildings, with the goal of reducing environmental impacts and improving the quality of life for all stakeholder groups.
The Company continuously works to ensure that air quality management is part of its sustainable organizational development strategy by integrating systematic measurement, control, and transparent, verifiable reporting measures. It also focuses on developing staff knowledge to appropriately oversee and innovate in environmental practices. The Company believes that effective air quality management not only mitigates health and environmental impacts but also strengthens credibility and trust as a socially responsible real estate developer.
Despite ongoing air quality control measures, the Company faces several challenges, such as constructing projects in highly densely populated urban areas that are at risk of generating dust and air pollution affecting nearby communities, controlling PM2.5/PM10 during piling and foundation work, which requires heavy machinery, and conducting air quality monitoring that relies on technology and personnel with specialized expertise. Additionally, continuously evolving environmental laws and standards pose another challenge that the Company must be prepared to adapt to.
Moreover, growing societal expectations for environmental responsibility have prompted SUPALAI to adopt more proactive measures. Air quality management must not only comply with legal requirements but also meet international standards and the expectations of consumers, investors, and surrounding communities. Balancing business growth with minimizing environmental impacts remains a critical challenge for the Company in all dimensions.
At the same time, these challenges present opportunities to create strategic differentiation for the organization. Investments in technologies to control dust and air pollution, such as automatic misting systems, indoor air filtration, and real-time air quality monitoring systems, help build confidence among residents and communities, and can be further developed into a selling point in green building (Green Building) development and future environmental building certifications.
In addition, improving air quality t is directly linked to the Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health and Well-being), SDG 11 (Sustainable Cities and Communities), and SDG 13 (Climate Action). Efforts in this area can enhance SUPALAI’s image as an organization that not only complies with regulations but also leads in social and environmental responsibility.
Ultimately, driving serious air quality management is not only about reducing environmental impacts but also about investing in the long-term sustainability of the business through building trust among customers, investors, and society at large, which will lead to truly stable and sustainable organizational growth.
Management and Strategic Approach
With a commitment to sustainable development, the Company has established comprehensive guidelines and practices covering both air quality management in construction projects and air quality management at the headquarters. The focus is on proactive pollution control, continuous monitoring and measurement, community communication, and fostering an organizational culture that values environmental responsibility. This approach ensures that business growth goes hand in hand with environmental protection and the well-being of society.
Therefore, to ensure that the Company’s air quality management is effective and efficient, and to prevent issues or negative impacts on communities and stakeholders, the Company has defined the following guidelines and practices for air quality management:
1. Air Quality Management for Construction Projects
Strict control of dust (PM10/PM2.5)
- Install and operate misting systems or dust capture systems at construction sites, especially during piling, structural, and foundation work.
- Cover construction materials that generate dust, such as soil, sand, and cement, and store them systematically to minimize dispersion.
-
Practices during periods when the concentration of fine particulate matter (PM2.5) in the air exceeds standard limits.
- The project will cooperate with government authorities in implementing air quality prevention and mitigation measures during periods when fine particulate matter (PM2.5) concentrations exceed standard limits, such as complying with requests to temporarily halt construction activities.
- During periods when fine particulate matter (PM2.5) concentrations in the air exceed standard limits, the project will suspend activities that generate PM2.5 dust.
- Position machinery and dust-generating activities to be as far away from receptors as possible.
- Install fire-retardant mesh sheets around the entire height of the building.
- Do not pile construction materials in a way that generates dust on the construction site.
- Require that trucks transporting soil in and out of the construction site be fully covered with tarpaulins.
- Do not operate machinery when not in use, and use electric-powered machinery to reduce noise from fuel-powered equipment.
- Plan transportation routes and schedules for materials to minimize dust and traffic issues, following designated roads, vehicle types, and timing as specified by local traffic authorities, and reduce the use of employee transport vehicles by providing shuttle services.
- Use construction equipment and techniques that generate less dust, such as employing prefabricated tank methods, to reduce dust dispersion.
- Provide sufficient water sources for spraying to suppress dust.
- Use enclosed transportation systems for dust-generating materials, such as covering the beds of all construction material trucks entering and exiting the project with tarpaulins to prevent dust dispersion.
- Ensure workers and misting systems are ready for use; whenever dust-generating activities are carried out, misting must be planned and executed.
- Burning of waste and construction materials on the construction site is prohibited.
- Excavate only the minimum necessary area; for other exposed areas, implement water spraying to reduce dust dispersion.
- Avoid cutting or drilling concrete surfaces; if necessary, water spraying must be applied before cutting or drilling.
- Stockpiled sand at the construction site must be stored in bunds and kept moist through regular water spraying.
- Cement brought into the construction site must be transported in fully sealed containers.
- Install misting systems every 5 floors of the building and along the project perimeter fence.
- Transport construction materials between 10:00–15:00 (except during urgent periods) using 10-wheel and 6-wheel trucks; 6-wheel trucks must have approval from traffic authorities.
- Clean truck wheels every time vehicles exit the construction site.
- Maintain construction site roads in good, usable condition at all times.
- Spray water on roads during dry seasons or when roads are dry.
- Post a speed limit of 25 km/h within the construction site and instruct all vehicles to drive cautiously to minimize impacts on nearby residents.
Air and Noise Quality Monitoring
- Measure dust and noise levels at least once a month, or more frequently when high-risk activities are being conducted.
- Install portable air quality monitoring stations or real-time monitoring devices in the project site to enable continuous and transparent monitoring.
Transportation and Material Handling Management
- Establish clear transportation routes and implement a truck wheel washing system to reduce dust dispersion on public roads.
- Set material transportation hours in accordance with local regulations to reduce impacts on surrounding communities.
