Advanced Work Packages (AWP) Services

Mega project execution is  extraordinarily challenging, with research showing that 65% of projects fail. Fortunately, Advanced Work Packaging (AWP) can reverse this performance. In extensive research by Construction Industry Institute (CII), AWP has been proven to be able to reduce total install cost by up to 10%, and improve productivity and safety performance by up to 30%.

AWP is an official best practice of the CII that begins during early project planning and spans the entire project lifecycle. AWP aligns engineering, procurement and construction to improve overall project performance by filling the gap between what design creates and what construction needs to execute work. Gain visibility into project details by supplementing design models with schedule resource, and construction related information. Your projects will benefit from better craft resource utilization, increased predictability, and lowered cost and risk to your project schedules. Many Owner Operators are now mandating the AWP best practice in their contracts and several EPCs are using the best practice to develop a competitive advantage.

AWP improves project outcomes through the alignment of people, processes and technology. Organizations need innovative approaches in the way projects are designed and constructed to satisfy today’s strict regulations and schedule demands. Our AWP solution offers an outcome-driven model combining technology, best practices, industry expertise, and training for successful AWP implementation.
