Optimal time for contractors to enter infrastructure projects
Paper in proceeding, 2021

involvement (ECI) is a project delivery method where the goal is to include construction knowledge into the design phase. This is
done by procuring the contractor during the design phase of a project. There are different approaches to which time the contractor
is introduced. This research paper aims to investigate the optimal time for contractors to enter infrastructure projects. In order to
do this, an empirical study was conducted, where interviews were held with nine representatives from an ongoing ECI project in
Sweden. The studied project was procured by the Swedish Transport Administration, and the contractor entered the project at the
beginning of the design phase, before a land acquisition plan had been developed. This is the first time in Sweden that a contractor
has been procured this early in a road project. The findings from the interviews show that responsibility, understanding, innovation,
risk management, relationship-building and implementation are the aspects that have been affected due to ECI. By analyzing and
discussing the results, it was concluded that involving the contractor as early as in the studied case has been beneficial, and that
involving the contractor as early as possible in infrastructure project is favorable.
