Impact Management in Construction

The Company recognizes its impact on the environment generated from the construction work and has established practices to manage the environmental impacts on community into 3 stages; the pre-opening, during the construction, and after the completion/ sales closed of the project.

Stage 1: Pre-Opening of the Project

  1. Conduct a survey of the area around the project to set the guidelines for preventing problems and potential impacts which may arise from the construction work to neighboring communities
  2. Conduct a survey of buildings, houses around the projects prior to the foundation pile drilling process and choose a method of drilling which has less impact to the surrounded building such as a bored pile system
  3. Set up water retardant and wastewater treatment system according to the standards set by the government entity
  4. Meet with the community leaders to conduct study and create mutual understandings with nearby communities

Stage 2: During the Construction

  1. Transportation of construction materials must not affect the residents around the project in the matter of noise, working time, dust & smoke. The projects have the protection set for the nearby community and residents.
  2. In case of the project is open for sale and already occupied, the Construction zones must be clearly divided from the customer's residence zones. In the case of the new phase is being constructed, the protection system will be tightly controlled so that there will be no impact to the customers.
  3. Responsible persons are assigned to supervise and assess problems if occur. There is continuous monitoring, prevention, and correction of impacts.

Stage 3: After Construction Completion

  1. Check the completeness of utilities and equipment
  2. Provide the instruction for use and maintenance of utilities and material equipment to meet the standards before handing over to the housing estate juristic person.
  3. Guidelines for practice and public relations activities are established on waste disposal and pollution management such as waste management, waste sorting and dust prevention.

Environmental issues are considered important and affects the quality of life increasingly. The Company intends to participate in conserving and improving the environmental problems. The development of environmentally friendly innovations, and the use of resources for the maximum benefit is conducted to create and preserve the sustainable environment for the society, community, employees, and residents in the project.

The Company has designed and produced the environmentally friendly products under the concept of “LH SMART, A Concept of Better Life” to improve the quality of life of the residents and to protect the environment through the following operations:

  • Design products and choose to use quality, energy saving and environmentally friendly materials, such as:
    • Battens: helps to ventilate the air around the eaves. The heat that accumulates under the roof tiles can be easily drained.
    • High quality gypsum board ceiling: lightweight, fireproof which helps filtering the heat from the roof, preventing the noise from upstairs and creating more beautiful and livable decorations.
    • Green tinted glass: The outstanding feature is UV protection which absorbs 35-50% of the heat that shines on the glass surface, thus reducing the use of air conditioners and saving electricity expense.
  • Innovation “ AirPlus Square (PM 2.5 Control).” The Company continues to emphasize the Indoor Air Quality-AIQ consecutively and has developed the latest air ventilation system. AirPlus Square: “A Breathable House, the PM 2.5 Dust Filter - Enjoy Every Moment / Enjoy Every Breath” is the air filling and dust filtering which was modified from the previous AirPlus system. The system will fill and ventilate the fresh air indoor and release the polluted air from the house. As regards the high quantity of dust outdoor, HEPA FIILTER (High Efficiency Particulate Air) is installed in AirPlus Square and efficiently filters 0.3 Micron dust, including PM 2.5. The system will automatically work to ventilate, adjust fresh air indoor consistently, and is user-friendly.The system can decrease the temperature and the accumulated humidity which can create musty odors, mold in the house, which have direct impacts to the hygiene of those who live in the society regard the air condition. It also drains out volatile chemicals (TVOC) which are used in the home as cleaning solutions and pesticides.

AirPlus Square is considered as an energy saving system that consumes less electricity, approximately 20 satang/ hour (calculating from the electricity unit at 4 Baht/unit). AirPlus Square is one of Land and Houses’ petty patents of intellectual property for the invention of new innovation.
