Problems of the early contractor involvement’s application

Anotace: In spite of all the already well-known benefits of Early Contractor Involvement, or, if necessary, selected subcontractors, most projects continue to be delivered through a one-stage selection of suppliers based on construction contracts that govern only the construction phase. Therefore, it is interesting and important to find out why - despite the obvious benefits of early involvement of the contractor in the project preparation process - the clients cooperate with contractors during the preconstruction phase of the project so rarely. This article discusses possible barriers to the use of such contracted cooperation in the pre-construction phase and their specifics for a particular type of project in terms of its size, complexity or type of supply system to be implemented. At the same time, the article focuses on the obstacles arising from the personal attitudes of the participants of the project towards the method of early involvement of the supplier, which, with the above question, why this method is still not that widespread in relation to its advantages, is closely related.
