The contractor tried to evaluate the risk involved and the corresponding price was suppressed. Inadequate time and information often adds additional costs to compensate for potential risks. This is just one reason for ECI development. In addition, the conflicting environment in traditional contracts hinders innovation and communication, adversely affects professional relationships and ultimately affects customer goals (Pullen). Initially, the unity is progressing, the joint efforts are successful This may summarize the main advantages of ECI.
Contractors are often at the design stage in the design phase, risk construction management and agency construction management contract relationships. Early involvement in the process provides the opportunity to help construct a realistic specification to reduce waste during construction. (William R. Mincks and Hal Johnston, 2012) Designers often recognize the physical properties of materials; however, they generally do not consider waste generated by the use of materials under construction. Contractors understand the material and the effective use of the waste in each application. This insight helps designers to select the best materials for each particular application. (William R. Mincks & Hal Johnston, 2012)
An important requirement of the IPD process is the collaboration and early participation of various stakeholders. Owners, architects, engineers, contractors, and subcontractors gather at the beginning of the project and contribute to each field through cooperation through client briefings or scopes. This collaborative approach will continue at all stages of the project until the project is completed and handed over to the owner. The scope of this approach is defined to create a common workspace for a variety of integrated ideas, and projects that cause differences in the site are thrown and resolved. Usually, those who need clarification of information during the implementation stage are part of the development team as a whole, so they can use traditional constructors to often identify incomplete areas in scope definition.
