GREEN CONCEPTS – II June 18, 2010


IPD 3d 01

LEED GA exam requires you to understand certain basic concepts pertaining to Green Buildings. Integrated Project Delivery (IPD) is one of those.

You must have heard of this term “IPD” several times in conferences, presentations and news articles repeatedly. Hardly people fail to mention this term in meetings these days. Especially, if it is meant for  business improvements or project delivery improvements. When I heard that term for the first time, it sounded very fancy to me. Something like…“NYPD..!”

Jokes apart. Project delivery is a process of assigning risks to those who have a better capability of handling it. Traditional project delivery method takes too much effort to segregate the tasks and assigning it to different parties involved in the project. As a result, traditionally, projects take too much of time for completion than what they should. The reason behind this is, everyone wants to play a safe game and if anything goes wrong, they tend to blame others to save their own back.             

It is this problem which necessitated the evolution of new project delivery methods. Some of the evolving project delivery methods are Design-Build (DB), Construction Management at Risk (CMR) and Integrated Project Delivery (IPD). The sole theme of all these evolving project delivery methods is to involve as many persons in the team in the early stage of the project. IPD went one step further and distributed the risk equally among all project participants including owner, contractor and designer.      

The following table distinguishes IPD from traditional project delivery methods on different measures.


Traditional Process IPD
Participants/Team Work Independently Collaborative, assembled – from conception to completion
Work Process/Work Sequence Linear Concurrent, Shared Information
Risk Individual Shared
Compensation Individual Based Team Based
Communication Paper Based, Digital Paper Based, Digital, Building Information Modeling
Cost Concern First Costs Life Cycle Costs

  1. Herculean task you have set for yourselves, I applaud your effort and I wish you success. However, one small correction under your table above: Work Process-Tradional Process you have stated “linear” which is the exact opposite of the current standard practice. Current practice is “siloed” where each participant; framer, electrician, plumber, insulation installer do their individual job without speaking to another contractor. They work within a vertical or siloed venue without sharing information or project direction. The goal is to become linear or horizontal in approach so everyone shares information and works on the same level to reach a common goal. The goal is what I like to call “common sense” building where everyone has a stake and uses best practices in both methods and products to make the most holistic solution to building possible.
    I again thank you for taking on so large a task.

    @William-Thanks a lot for your appreciation and well wishes. Your interpretation on “linear work process” is appreciable and is valid at its context. But, the “linear” word in table signifies the “linear schedule” followed by the traditional process, I mean Design>>Bid>>Build, which is not the case with IPD where these three phases overlap with each other, to make it a “concurrent process”.

    Once again thank you for your effort and well wishes.
