Deputy BMA governor Pol Lt General Amnuay Nimmano told the press conference on Monday the meeting on June 29 would involve agencies such as the Metropolitan Police Bureau, the Engineering Institute of Thailand, as well as contractors involved in railway projects.

Deputy governor Thaweesak Lertprapan said that large railway projects can take three to five years to complete and related agencies and contractors must be responsible together.

He said the meeting would table rules and regulations to follow when carrying out construction projects to ensure related agencies were notified.

He said some projects involved cutting city sewage pipes or damaging road surfaces so agencies must discuss this to follow the project and participate in planning to reduce the chance of accidents.

The meeting was called following several incidents on major projects. They including a March 17 incident at the Green Line extension on Phahonyothin Road when a giant metal beam fell on a car narrowly missing a woman; on April 28 a crane collapsed at a Red Line construction site in Don Muang district and killed three workers; and on June 7 a crane, used in the Green Line construction, tipped over near the Royal Thai Air Force Academy on Phahonyothin Road, causing traffic problems.
