Application of Advanced Work Packaging in Structural Steel Installation: Optimization of Construction Execution of a Mining Project in Southeast Asia

Abstract Advanced Work Packaging (AWP), introduced in 2011 by the Construction Industry Institute as a project management strategy designed to improve outcomes in construction projects, was adopted in a mining project in Southeast Asia. This study presents the core principles of AWP, the preparation of Installation Work Packages for the structural steel assemblies of the said project, and the importance of close collaboration and communication between the Workface Planning (WFP) team and other stakeholders. The AWP concept breaks down a construction project into smaller and more manageable units called Installation Work Packages (IWPs). These packages contain information about the work scope, permits, labor, tools and equipment requirements, special safety considerations, material take-offs, installation procedures, and other related constraints that need to be cleared prior to construction of the IWP scope. In addition, central to AWP's philosophy is the early formation of a collaborative team of professionals comprising of discipline engineers and designers, supply chain experts, steel fabricators, rigging engineers, and site managers. Various challenges may significantly affect the performance of construction projects. In this mining project, geographical configuration of the site and complicated transportation routes posed challenges in the delivery of materials from the warehouse to the laydown areas. Moreover, unintentional material fabrication lapses and unforeseen constructability issues necessitated revisions of related engineering drawings or modification of supplied materials. Similarly, complex engineering details identified in the pre-construction phase required simplified solutions. This paper shows how regular alignment between concerned groups in the planning, design, engineering, procurement, fabrication, and construction phases can enhance project performance by proactively addressing potential causes of delays, such as those mentioned. Upon the project's completion, the structural IWPs were accomplished ahead of the projected baseline finish date by about three (3) months and the hard deadline set by the client was met despite the challenges faced. The use of customized in-house templates and software applications like Navisworks Simulate expedites and assists in the preparation of IWPs; hence, this paper also briefly explores the potential of other innovative applications like Smart Construction to improve the automation of IWP preparation. As the efficiency and effectiveness of AWP consequently improve project performance, its demand and application in diverse types of projects and industries become inevitable and a key solution to the most common challenges faced in construction execution.
