Website: Project Life Cycle Management Laboratory
The life cycle management laboratory at the University of British Columbia (Okanagan campus) is equipped with state-of-the-art hardware and software to conduct both micro and macro level Life Cycle Assessments (LCA) in engineering projects. The lab has facilities to observe any engineering operation/process through high resolution wireless cameras and analyze data with comprehensive LCA databases. In addition to the LCA software, the lab is equipped with Building Information Modeling (BIM), Life Cycle Costing (LCC), Geographic Information System (GIS), Social Impact Assessment, Risk Management, and Statistical Data Analysis software. The laboratory was initially funded by a NSERC RTI grant.
