insights of all participants so as to optimize project results, to increase value to the
owner, to reduce waste, and to maximize efficiency through all phases of design, fabri-
cation, and construction of the project. IPD teams can include members other than the
traditional owner, engineer, and other integrated processes are also acknowledged and
®
encouraged in sustainable ratings systems such as LEED . IPD claims to provide the
following benefits for the three major stakeholder groups.
Owner-Operators
Through continuous sharing of project data by employing advanced interactive soft-
ware, that is, BIM and staying on top of ongoing project communications, CHP owner-
operators are kept up-to-date as CHP plant designer alternatives and related cost are
decided by remaining in a position to respond to choices in a timely manner thereby
commencing early construction and improving sooner access to positive cash flow from
CHP operations while expediting their project team’s grasp of CHP owner-operator
expectations. This should improve their team’s ability to manage and control budgetary
goals leading to improved schedules, lower life-cycle cost, and improved quality and
sustainability.

Constructors
IPD also can enable constructors to apply their expertise when selecting construction
methods earlier in the design process, hopefully resulting in improved project construc-
tion milestones and financial outcome. Enabling early constructor’s participation in the
design phase often results in strong preconstruction planning, more timely and informed
understanding of designer intent, anticipating and resolving design-related issues, and
visualizing best construction sequencing prior to the start of construction. After the
start of construction, there is more likely improved cost control and budget manage-
ment, all of which increases the likelihood that project goals, including schedule, life-
cycle costs, quality, and sustainability will be achieved.

Designers
IPD also can energize improved communication and coordination among the various
designers who can benefit from the early contribution of constructors’ suggestions
thereby avoiding constructibility issues later on. Furthermore through early application
of value-engineering and interactive discussions, accurate budget cost estimates are
more likely to lead to better design decisions, resolve preconstruction issues, improved
project quality, and financial outcomes to all parties and a higher level of effort during
early design phases, reduced overall documentation time, and improved cost control
and project management, thereby improving the likelihood that project goals, quality,
and sustainability are achieved.

Decision Makers
IPD clear documentation methods enable improved transition from traditional design
deliverables. Furthermore IPD document process encourages the CHP owner-operator,
design engineer(s), architect, and constructor to engage earlier into a collaborative team
effort which can improve matters throughout the design and construction phases. The
CHP owner-operator and architect/engineer team must agree to be bound by the terms
of AIA B195 and A295 which should also assist the CHP owner-operator in early
development of a list of prospective and qualified contractors.
