Integrated project delivery, sometimes referred to as IPD, is an alternative construction project delivery method that encourages a high degree of collaboration between a building owner, project designer and contractors throughout a building's construction process to maximize efficiencies. IPD also can fit well with some roofing projects.
IPD integrates people, systems, business structures and practices into a process that collaboratively harnesses the talents and insights of all project participants to optimize efficiency and reduce waste through all phases of project design, fabrication and construction.
IPD proponents report it improves project efficiencies and reduces waste, which significantly affects project costs. Also, the IPD process helps building owners achieve their primary project goals, such as reduced costs, improved energy efficiency, sustainability and ease of maintenance. Integrated construction processes are acknowledged and encouraged in sustainable rating systems, such as LEED,® and energy-efficiency and sustainability standards, such as ASHRAE 189.1, "Standard for the Design of High-Performance Green Buildings."
