Using a Design/Builder The functions of architect and construction management are combined in this arrangement that was one of the first to simplify the construction process for owners. Who does what? A single firm develops the design of the project, jumps through all the legal hoops, then hires subcontractors to complete the work. The money is handled in the form of a lump sum or a guaranteed maximum price. This approach works best for owners who need a central point of responsibility for the project, but feel capable of developing the goals and evaluation criteria of the project themselves. Tapping the full resources of the Alter Group companies, we combine innovative design with deep experience in the practicalities of construction.
