Owners, especially in the building sector organize projects based on having a design team and construction team. The design team is led by an architect in the case of a building project and by and engineering firm if a civil works or industrial project. The construction team is led by a construction management firm or general contractor. Owners may elect to purchase direct from OEM suppliers and may opt to place the construction management firm over all of the service providers. Often times owners will engage a program or project management team to support the administrative aspects of a project.
