Green Construction Capability Model (GCCM) for Contracting Companies

Abstract

Construction project has been considered as one of the contributors to the environmental destruction, therefore green construction becomes the important issue in many countries including Indonesia. However, the success of green construction implementation depends on the capability of contractors, therefore model to assess the capability of contractors to build the projects based on green construction approach becomes important need to be developed. This study is aimed to develop a model to assess capability level of contractor to implement green construction. The model has adopted the concept of Capability Maturity Model (CMM). The model assesses the capability level of contractors based on 16 factors that are categorized into seven aspects of green construction. Those aspects are energy conservation, water conservation, safety and health, environment management, appropriate land use, air quality, sources and cycle of materials. While the capability of contractors to implement green construction is classified into five levels: initial, repeatable, defined, managed and optimizing. Finally, the assessment model named Green Construction Capability Model (GCCM) is proposed as a tool to assess the capability level of contractors to implement green construction.
