It seems that recession is bringing new opportunities to test and practice emerging technologies in AEC industry. Having lesser projects in hands, AEC professionals and owners are looking towards experts and academicians to come up with innovative solutions to effectively implement new technologies and management philosophies to increase efficiency, increase labor productivity, reduce waste and decrease environmental impact in the overall life cycle of a project. In order to achieve this milestones contribution of BIM, LEAN and GREEN movements appears appreciable.
Building Information modeling (BIM) is helping project participants collaborate and at the same time it is helping to reduce waste (by conflict detection), increase performance (by energy analyses) and visualize the project. BIM is emerging as a tool that is helping integration of overall project delivery.
Lean production system introduced first time by Onho in Toyota car manufacturing unit is emerging as a management philosophy applicable to wider range of industries. AEC industry being one of them is coming forward to embrace lean thinking and increase profits to their organizations.
Green movement is an initiative to decrease impact of human activities on the environment. US Green Building Council (USGBC) introduced LEED rating system to measure the greenness of buildings. Although LEED doesn't address all the issues of sustainable construction and is not perfect but it is a good initiative towards a sustainable future.
Apart from very ideal portray of any of BIM, Lean or Green in building construction, increased productivity, energy efficiency and increased building performance will surely affect the bottom line in a positive manner.
