Abstract
The environmental management is essential for construction projects. The environmental management cost for construction projects is used for various purposes to control the environmental pollution and treat the wastes generated from the construction sites. Six construction cases were analyzed to compare the environmental management cost. The proportion of environmental management cost for total construction budget should be higher than 0.70% in redevelopment projects and 0.30% in newly constructed buildings, respectively, but every six construction cases did not meet the legal requirement. Redevelopment projects expanded more environmental management cost than the newly constructed projects especially in noise control and wastes treatment. In case of apartment construction projects, the proportion of environmental management cost of redevelopment buildings is 2.4 times higher than the newly constructed buildings, but in all cases, paid more attention to the noise and waste controlling measures than the wastewater treatment. It is needed to ensure the cost-effectiveness of environmental management for achieving the eco-friendly construction sites.
