Construction is a high-risk activity, not only for the workers but also for third parties and nearby properties. To prevent accidents and undesirable impacts, the law has established strict site safety measures. Complying with these regulations is not just a matter of law; it is the heart of completing a project safely and without problems.

‍

6.1 The Importance and Objectives of Site Safety Measures

Construction safety measures have the following main objectives:

• Protecting the lives and health of workers: Preventing work-related accidents such as falls, being struck by falling objects, or being caught in machinery.
• Preventing harm to third parties: Ensuring the safety of passersby or residents near the construction site.
• Protecting property: Preventing damage to the building under construction, equipment, and neighboring properties.
• Complying with the law: To ensure construction proceeds following legal regulations and to avoid legal penalties.
• Building a good image: Demonstrating the responsibility and professionalism of the developer.

6.2 Directly Related Laws and Regulations

Safety regulations for construction sites are covered by several laws, as follows:

6.2.1 Building Control Act, B.E. 2522 and Ministerial Regulations

• Notification of Construction Commencement (and Signage): After receiving a construction permit, the contractor must notify of the start date and display a sign showing the construction permit, as well as clear safety warning signs at the site.
• Provision of Fencing/Barriers: A fence must be erected around the construction area with clear entrance and exit gates to prevent unauthorized individuals from entering the area.
• Prevention of Falling Objects: There must be netting covering the building, panels to catch falling objects, or other measures to prevent debris or tools from falling into public areas or onto adjacent properties.
• Dust and Noise Management: There must be measures to control dust from construction (e.g., water spraying) and to control noise levels so they do not exceed the prescribed standards and disturb the nearby community.
• Prevention of Electrical and Plumbing Hazards: Temporary electrical and plumbing systems on the site must be installed safely and according to standards.
• Stability of Scaffolding and Temporary Structures: Scaffolding, shoring, or other temporary structures must be designed and installed to be stable and safe according to engineering principles.

6.2.2 Occupational Safety, Health and Environment Act, B.E. 2554 (under the Ministry of Labour)

This act contains detailed and strict regulations for construction work, focusing directly on the safety of the workers:

• Creation of a Safety Plan: The employer (contractor) must create a safety, occupational health, and environmental work plan.
• Provision of Personal Protective Equipment (PPE): Such as helmets, safety shoes, gloves, goggles, and safety harnesses. All workers must wear PPE appropriate for their type of work.
• Safety Training: Provide safety training for employees.
• Inspection and Maintenance of Machinery/Equipment: Machinery, equipment, and tools used in construction must be in good working condition and regularly inspected.
• Working at Height: There must be measures to prevent falls from height, such as guardrails, safety nets, and the use of personal fall protection equipment.
• Fire Prevention: Have fire extinguishers and an emergency plan in case of fire.
• First Aid: Have a first aid kit and personnel trained in basic first aid.

6.3 Notification of Construction Commencement and the Role of Officials

• Notification of Commencement: After receiving the Construction Permit (Form Or.1), the permit holder or contractor is responsible for notifying the local official of the start date of construction, specifying the start date and the construction supervisor.
• Signage: A sign displaying the construction permit and safety warning signs must be installed in an easily visible location at the construction site.
• Inspection by Officials: Local officials have the authority to inspect the construction site at any time to ensure compliance with laws and safety measures.

6.4 Community Impact and Preventive Measures

Construction sites often impact the surrounding community. Having appropriate preventive measures will help reduce problems and complaints:

• Noise: Control working hours, use noise-reducing equipment, or erect temporary fences/sound barriers.
• Dust: Spray water, use dust filtering nets, and cover material piles.
• Debris/Waste: Manage debris systematically, remove it regularly, and prevent falling objects.
• Traffic: Plan the transport of materials and equipment so as to not affect traffic, and provide traffic controllers.
• Neighbor Disturbance: Notify neighbors in advance of activities that may cause loud noise or temporary impacts.

6.5 Penalties for Non-Compliance with Safety Laws

Neglecting safety measures on a construction site carries severe penalties, as follows:

Under the Building Control Act:

• Fine: A daily fine may be imposed for failure to comply with an official's order.
• Suspension of Construction: If the construction is found to be unsafe or illegal, the official has the authority to suspend construction immediately until it is corrected.
• Imprisonment: In cases that cause danger to life and property.

Under the Occupational Safety, Health, and Environment Act:

• Fine: The employer may be fined for not providing welfare, safety equipment, or training.
• Imprisonment: In cases that cause danger to an employee or others.

6.6 Scenario Example: "Khun Ja's" Story from the Sidewalk about Two Different Construction Sites

• Khun Ja: An office worker who walks the same route to work every day.
• Site A - "Somchai General Contractor": A contractor building a 3-story commercial building, focusing on speed and saving costs.
• Site B - "Professional Construction Co., Ltd.": A contractor building a small office building with systematic management.

"Khun Ja's" Observation

On her way to work, two new construction projects started at the same time on the same street, but what she observed every day was completely different.

At Site A, "Somchai's Site," Khun Ja found that:

• The project fence was just old corrugated zinc sheets, loosely put up, with gaps a person could slip through.
• There was no project sign or sign displaying the construction permit (Or.1), making it impossible to know who was responsible.
• The building under construction had no dust nets or panels to catch falling objects, making her feel anxious whenever she walked past, worrying that a piece of concrete or a tool might fall.
• Most workers wore casual clothes, some wore sandals, and almost no one wore a helmet.
• Looking up to the upper floors, she saw workers on scaffolding without wearing safety harnesses or any fall protection equipment.

Meanwhile, at Site B, "Professional Construction's Site":

• There was a strong, fully enclosed fence around the construction area with a clear entrance and exit gate.
• At the front of the project, there was a large sign displaying the project details, the contractor's name, contact number, and, importantly, a copy of the construction permit was openly displayed.
• The building itself was neatly wrapped in green safety netting, which made her feel safe walking past.
• All workers wore uniforms, helmets, and safety shoes, looking organized and professional.
• Looking up, she saw that all workers at height were using safety harnesses, properly clipped to the structure according to safety principles.

The Turning Point and Different Outcomes

One day, the unexpected happened at Site A. A piece of brick fell from the second floor, narrowly missing the head of a motorcycle taxi driver. This incident led to a complaint being filed with the district office.

A few days later, a local official came to inspect Site A and found numerous safety violations under both the Building Control Act (public safety) and the Occupational Safety Act (worker safety).

• Result of Site A: Somchai received an immediate stop-work order and was fined daily until all safety measures were corrected according to the law, whether it was building a new fence, installing netting, or providing PPE for the workers. This caused the project to be halted and severely delayed.
• Result of Site B: The project by Professional Construction Co., Ltd. continued smoothly according to plan and was completed on schedule, without any accidents or complaints.

Conclusion from the Scenario: This story reflects that investing in safety measures is not a "wasted cost" but the most important "investment" in construction. Strict compliance with the law not only protects the lives of workers and the public but also prevents delays and massive fines, allowing a project to be completed professionally and sustainably.

6.7 Conclusion

Safety on a construction site is non-negotiable. Developers, contractors, and all project owners share the responsibility of strictly complying with safety laws and regulations. Investing in appropriate safety measures not only helps protect lives and property but is also a crucial investment to ensure your project proceeds smoothly, reduces legal risks, and builds trust with all parties involved.
