Integrated Project Delivery

Integrated Project Delivery (IPD) is a collaborative alliance that harnesses the talents and insights of all participants stakeholders involved in a project. The end result is project optimization, increased owner value, and reduction in the amount of waste produced.   

There are eight main phases involved with IPD: 



Traditional Project Delivery

Integrated Project Delivery


Fragmented, assembled on “just-as-needed” or “minimum-necessary” basis, strongly hierarchical, controlled

An integrated team entity composed of key project stakeholders, assembled early in the process, open, collaborative 


Linear, distinct, segregated; knowledge gathered “just-as-needed;” information hoarded; silos of knowledge and expertise  

Concurrent and multi-level; early contributions of knowledge and expertise; information openly shared; stakeholder trust and respect 


Individually managed, transferred to the greatest extent possible 

Collectively managed, appropriately shared 

Compensation / Reward

Individually pursued; minimum effort for maximum return; (usually) first-cost based 

Team success tied to project success; value-based 

Communications / Technology

Paper-based, 2 dimensional; analog 

Digitally based, virtual; Building Information Modeling (3, 4 and 5 dimensional) 


Encourage unilateral effort; allocate and transfer risk; no sharing 

Encourage, foster, promote and support multi-party agreements


Lean Project Delivery 

Another term often used to refer to a form of Integrated Project Delivery is Lean Project Delivery System ™ (LPDS), a term developed by the Lean Construction Institute (LCI). Many of the principles attributed to Lean Project Delivery are similar to those attributed to IPD. In fact, in this era of evolving terminology, many refer to IPD as ―Lean Project Delivery‖ where the application of ―lean thinking‖ and lean principles are applied throughout the project. 

Followers of IPD treat lean principles along with the resulting efficiency.

Lean Construction / Lean Project Delivery 

The Lean Approach to Construction is drawn from principles developed in manufacturing. The overriding goal of the lean approach is to minimize the waste in the delivery of the project through the optimization of all resources without duplication of efforts. 

A common definition of lean construction is: The continuous process of eliminating waste, meeting or exceeding all customer requirements, focusing on the entire value stream, and pursuing perfection in the execution of a constructed project.

BIM is technology that supports the delivery of projects in a more collaborative and integrative way. Collaborative, integrated teams are using building information models in a collaborative, computable way to achieve better decision-making. Collaborative decision-making strategies are, of course fundamental to the IPD process. Even if, hypothetically, an IPD project may be delivered without using BIM and vice-versa, the real benefits will be seen only when BIM methodologies are applied to IPD processes. 

The consistency of the "I" is the real value that BIM can provide to an IPD process: information integration, reliability and interoperability are at the heart of the tool. This can only happen when the information model is shared transparently and becomes an integral part of the decision-making process throughout the design, construction and management of the building. 

BIM can be of great value for all owners, both public and private. In the public arena, most owners are also managers of their buildings, and it is here that BIM adds major value. Most have experienced the loss of major project information between the end of construction and beginning of the management phase; as a result, most owners understand how difficult it is to collect, organize, manage and store the many different types of information required for long-term facility management. BIM can help the owner in this major task: it can be seen as a repository of major sets of information or be linked to other information perhaps not stored within the model. BIM for facility management is the next big step for a real use of this new technology. At this point, little research exists documenting the benefits of BIM for facility management, but it is a natural step in the building lifecycle to capture information at the end of construction and beginning of operations.
