the duct section. The design of the foundations caused the duct to hang up on the concrete prior to contact with grade. The last restraint was identified when the remaining structural steel was installed between grade and top of the structure. The bottom of this steel interfered with the top of the duct. This would require that the duct section be removed prior to installation of this steel, thereby increasing the duration of the schedule. The first problem with the structural column was solved by cutting out the portion of the duct stiffeners that was interfering. The second and third problems was solved by modifying the foundation design, eliminating the hang up and enabling the top of the duct to be 18 inches lower than the bottom of steel when lowered to grade. The 3-D construction model identified these deficiencies early enough in the project to permit effective constructibility analysis and value engineering. If the problems of the duct hanging up on the foundation and the structural steel interference were not identified until the outage commenced, the impact on the schedule could have been severe. Power Plant Environmental Systems Retrofit Stone & Webster's 3-D modeling system has also been used on a 550 Megawatt pulverized coal fossil power plant. The project consisted of retrofitting the existing scrubber units, removing precipitator units, and replacing 800 tons of exhaust duct during a twelve week outage. During the proposal, 3-D computer models were developed of the existing plant configuration and the owner's conceptual new duct design. The models were developed from the existing plant drawings and a preliminary walkdown of the plant. The models were completed by two construction personnel in three weeks and included all facilities and equipment associated with the plant's flue gas desulfurization area (Figure 2). The models initially were used to help Stone & Webster personnel understand the scope of the outage work and facility layout for the project. They were also used to quickly determine quantities of duct work, structural materials that were to be restored, removed, or installed, and the surface area of the structural steel for sandblasting and painting. However, the main use of the models was to develop a construction sequence to visually verify that the project could be completed on schedule. This approach was used to convince Stone & Webster's management, as well as the owner, that the tight schedule could be met with minimal risks. After the contract award, Stone & Webster conducted the detail design of the plant building upon the model developed in the proposal. Three-dimensional modeling was used for all new 38
