Constructability innovation in piperack design for refinery project

摘要

Increased competitiveness in the construction industry requires the improvement of audconstruction company’s capabilities to combine quality with economic and scheduleudaspects. Many studies and procedures in quality improvement focus on project qualityudimprovement techniques and efficiency such as total quality management, valueudengineering, designability, contractability, constructability, operability,udmaintainability and other quality improvement techniques. This research focuses on constructability, which is the optimum use of construction knowledge and experienceudin planning, engineering, procurement and field operation to achieve overall projectudobjectives. A case study was performed at an Indonesian refinery project, whichudapplied the design and build type of contract. The case study aims to discuss andudanalyse the implementation of constructability innovation in the planning and designudstage of the refinery project, focusing on optimization and improvement of pipe rackudstructure. The case study shows that the implementation of constructability during theudplanning and design stage increased the project performance and reduced the projectudcost.
