The purpose of this research is to study the construction safety measure for working at height. The safety measure for working at height in this research is developed by referring to the Ministerial Regulations prescribing the standard for administration and management of occupational safety health and environment for construction work 2008. The average of safety is low in five high rise construction projects in Bangkok metropolitan. So all parties involved in contractors need to focus on safety measure for working at height.

The purpose of this research is to study assessment of safety in construction of building projects. The safety assessment form was developed by referring to the Ministerial Regulations. The safety assessment composed of 8 categories: (1) construction site perimeter (2) electricity and fire protection (3) crane (4) passenger lift and material hoist (5) welding (6) fall protection (7) temporary scaffolding and stairs and (8) personal protective equipment. Based on the safety assessment of the construction site the size of the large building exceeds 2000 m2 and height exceeds 23.00 m. in the Bangkok metropolitan has of 20 buildings. The average of safety is 80 percent. By construction site perimeter the highest average and the fall protection has the lowest mean. So all parties involved workers contractors and project owner in particular need to focus on safety work to prevention against falls from high in order to reduce the loss of property life company reputation including the morale of the work as well.

The purpose of this research is to study the effect of safety measure to construction productivity for ceiling activity by studying a construction of buildings in Bangkok. The safety system composed of (1) stable scaffolding system (2) providing clean and not slip walkways on the scaffold (3) installation of handrails not less than 0.90 meters in height (4) installing stairs (5) providing personal protective equipment for workers (6) are responsible for scaffolding and (7) scaffolding permit document. Cost of the safety system is 23908 baht or approximately 33 baht/m2. Productivity rates for prior and after the used of safety system are 1.57 and 1.41 m2. /person/hr. respectively. The productivity declines for approximately 10.19 % the working time for ceiling could take longer for 10.45 % and labor cost could increase for 10.19 %.
