When faced with a potential failure of an existing system, a fast track project was introduced and approved to commence construction with an incomplete design. This allowed material to be ordered and the civil portion of the project to be completed early. However other aspects of the project encountered problems. Fabrication of the piping and structural was completed concurrently with design.
This led to inefficient fabrication and out of sequence deliveries. The construction sequences had been determined by the completion of the design, not on the most efficient Path of Construction. As a result, vendor drawings for equipment were not finalized prior to fabrication, leading to costly rework and delays.
In following the AWP Best Practice, early involvement of teams throughout the project including the Construction Team allows collaboration with designers to determine the Path of Construction and remove constructability bottlenecks.
The development of Engineering Work Packages (EWPs) and Construction Work Packages (CWPs) allows identification and management of constraints in order to assist the fast track schedule and identifies long lead
time items that need to be ordered during the planning process.
Development of IWPs, based on the CWPs, allows for constraint free execution. By utilizing the AWP Best Practice, relevant Engineering Packages are completed prior to fabrication, and an efficient design is completed more quickly, allowing for a structured execution strategy, and addressing the issue. O3’s Constraint Management component helps team members collaborate on what may be holding
up the release of work packages.
