If the engineering and environmental studies both recommend constructing one of the alternatives studied, then the project will transition into the design phase. This typically is done in two parts, with both parts including numerous technical reviews for compliance with design standards. First, the preliminary engineering documents are completed, which develops the design to the 30 percent level. This level of design is sufficient to define the right of way requirements so that right of way acquisition can begin. The second level, or final design, takes the project from the 30 percent to the 100 percent level. These 100 percent documents make up a construction bid package with sufficient detail for a contractor to bid the project.
