Cost plus in construction is a type of contract which ensures that the contractor will be paid for all eligible costs associated with completing a project, as well as an additional fee meant to cover the contractor’s overhead expenses and any profit margin. It allows the contractor to adjust their expenses to reflect any changes in required materials or labor costs during the course of a project. This makes cost plus contracts attractive for larger construction projects, since it ensures that contractors are fairly compensated for their services without having to rely on fixed prices.
