Integrated project delivery


Integrated project delivery (IPD), is a collaborative alliance of people, systems, business structures and practices into a process that harnesses the talents and insights of all participants to optimize project results, increase value to the owner, reduce waste, and maximize efficiency through all phases of design, fabrication, and construction.

There are eight main sequential phases to the integrated project delivery method:

The construction industry has suffered from a productivity decline since the 1960s while all other non-farm industries have seen large boosts in productivity. The problems in contemporary construction include buildings that are behind schedule and over budget as well as adverse relations among the owner, general contractor, and architect. Using ideas developed by Toyota in their Toyota Production System and computer technology advances, the integrated project delivery method is designed to solve these key construction problems. The new focus in IPD is the final value created for the owner, the finished building. Rather than each participant focusing exclusively on their part of construction without considering the implications on the whole process, the IPD method brings all participants together early with collaborative incentives to maximize value for the owner. This collaborative approach allows informed decision making early in the project where the most value can be created. The close collaboration eliminates a great deal of waste in the design, and allows data sharing directly between the design and construction team eliminating a large barrier to increased productivity in construction.

Integrated project delivery is a delivery system that seeks to align interests, objectives and practices, even in a single business, through a team-based approach. The primary team members include the architect, key technical consultants as well as a general contractor and key subcontractors. The IPD system is a process where all disciplines in a construction project work as one firm, creating faster delivery times, lower costs, no litigation and a more enjoyable process for the entire team – including the owner.

IPD combines ideas from integrated practice and lean construction to solve several problems in contemporary construction such as low productivity and waste, time overruns, quality issues, and conflicts during construction among the key stakeholders of owner, architect and contractor. The growing use of building information modeling in the construction industry is allowing far greater information collaboration between project participants using IPD and considered an important tool to increasing productivity throughout the construction process.
