Digital advanced work packaging – a case study in construction-led delivery

Abstract

Advanced Work Packaging (AWP), a Project Management methodology, has been adopted to deliver the Viva Energy Gas Terminal Project. AWP is a recognised industry best practice, which aligns Engineering, Supply Chain Management and Construction towards an optimised execution sequence, driven by Construction and Commissioning. AWP accomplishes this through standardised project planning and effective information and data flow for the duration of the project under a unified plan. Worley has developed a unique framework and digital delivery method for AWP based on the Construction Industry Institute standard. The underlying strategy that enables AWP to succeed is defining the execution sequence early and collaboratively, as well as, committing to a unified plan between Engineering, Supply Chain, Fabrication, Construction, Completions and Start-Up. Construction-led delivery using digital AWP enables the sequencing of engineering deliverables based on Construction and Commissioning sequences, allowing the right people to work on the right issues at the right time. Through application of an AWP compliant Level III Schedule that provides visibility across Engineering, Procurement and Construction, we have been able to determine the impact of delays and mitigate to facilitate successful execution. Based on the application of AWP on projects using the Construction Industry Institute standard, significant improvements in overall project delivery outcomes have been achieved; with productivity improvements of up to 25%, improved schedule outcomes with 80% of projects either on time or ahead of schedule and Total Installed Cost savings of 3–10%.
