What is Integrated Project Delivery?

Definition

Integrated Project Delivery (IPD) is a project delivery method distinguished by a contractual agreement between a minimum of the owner, design professional, and builder where risk and reward are shared and stakeholder success is dependent on project success.  [1]
To explain it in simple words, IPD is project method where owner, design professional and builder are bound by a contract. All participants share risk and rewards, therefor the success is also are up to participants. This method bounds everyone in project to one major goal and shares each interest.

Overview

Most of all, IPD lets construction management and at least some key trade contractors to be involved in the project with the client and design team in early stages of design. Thus, these CMs/Construction managers and trade contractors are selected on the basis of qualifications and not on price. Far more common understanding is developed between participants because of early integration. The design moves forward with constructors contribution about cost, constructability and value, allowing designers to make better decisions with fewer and less negative drawbacks. Also the client plays quite active role in designing of the project, so he is assured that everything goes as he wants. 
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.[2]
Concerning phases of IPD there are eight of them: conceptualization phase, criteria design phase, detailed design phase, implementation documents phase, agency review phase, buyout phase, construction phase, closeout phase and facilities management. I will talk through phases next time including team composition.
