Productivity and performance in construction projects are governing factors for a timely and high-quality end product. Research is done on identifying possible root causes that affect the productivity and performance based on the local construction industry. The team works with professionals in the industry to develop frameworks to evaluate lost time and resources as well as tools and techniques to ensure improvement in productivity and performance.
