- Limit possible entrance to construction site (or use construction sign)
- To prevent students or unauthorized personnel enter high risk construction area
- Prepare emergency program in case of accident happening
- To protect construction workers in the site; students and teachers in the school
- A excavator, equipped with an engine(115 hp@ 2400 rpm) had a overall noise level of 80.5 dB at 50 feet.
- Solution: with improved exhaust and intake muffling, and three sound panels around the engine, the overall level was reduced to 71. 5 dB.
- Temporary barriers/enclosures (e.g. plywood with sound absorbing materials) can be built around noisy equipment.
- These barriers can significantly reduce noise levels and are relatively inexpensive.
- The most used alternative, due to its low cost of implementation and excellent results. Water should be applied at least three times a day or more, depending on the atmospheric conditions.
- A water tanker is driven on-site spraying water over the affected areas preventing dust from airborne.
- Provide effective dust screens, sheeting or netting to keep tiny particles of dust and sand from the construction site
- To protect the school community from air pollution
- For Traffic control, we would need two construction workers to control the traffic near the construction site
- Use of traffic sign to redirect traffic to different route
