BE Magazine - Volume 5, Issue 1 - (Page 34) GEOSPATIAL MicroStation allowed six civil engineers from two separate offices to work simultaneously on different areas of the site. A digital terrain model (DTM) of the finished grade was created for each area of responsibility using InRoads, which was then used to create utility profiles and to accurately calculate earthwork quantities. The original survey DTM was modified during the design process using MicroStation to incorporate each of the previously constructed projects. The project workspace environment of MicroStation allowed drawing files to be shared between several projects, which eliminated the need to create several versions of a drawing file. It also allowed changes in one project to be reflected across several other projects. The DTMs created during the design process were also used to create a 3D triangulated surface of the final grades. Design visualization features included with MicroStation allowed renderings of the complex to be created for customer presentation. To comply with Omaha District standard operating procedures, CADD files containing the existing and finished grade contours were included in the advertised documents. This allowed earthwork subcontractors to quickly and accurately prepare bids. Construction on the motorpool complex is scheduled to be completed in December 2008. in March 2006 and construction is scheduled to be completed by April 2008. Grading of the 230-acre motorpool complex required extensive cuts and fills. A separate project to rough grade the motorpool site was required to allow time was given to the COF/TEMF designers for each new building. The final project included the site work for the motorpool complex, which included concrete hardstands, POV parking areas, access roads, utilities, and fencing. Leo A Daly v The entire complex was designed and constructed in 11 separate projects for soil in excavated areas to rebound and allow new buildings within the motorpool complex to be constructed at an accelerated pace. Because much of the excavated material was unsuitable for embankment construction, it was used to construct berms to serve as a barrier between the adjacent training ranges and the motorpools. A stormwater detention basin was constructed to reduce peak flows and improve stormwater quality from the motorpools. The team designed and constructed the project within seven months and moved approximately 1 million cubic yards of soil. Once the motorpool site was rough graded and floor elevations established for the buildings, construction of the COF and TEMF buildings could begin. These buildings were procured using separate designbuild contracts, with each of the contracts awarded to M.A. Mortenson of Minneapolis. A product-line approach was selected to procure the motorpool complex buildings. This means the same design is used repeatedly, which reduces design and construction costs. Further, the standardized facility provides a familiar workspace as troops move from one installation to the next. In addition, new water, gas, and electrical power utilities were needed for the COF and TEMF buildings because of the road relocation projects. A utility tie-in location Over 50 acres of roller compacted concrete pavement was used for the motorpool hardstands. The team designed the storm drainage system to carry water to the detention basin constructed as part of the rough grading project, and industrial waste drain lines were designed to connect each of the TEMF buildings to Fort Carson’s industrial waste drain system. The accelerated project schedule required several engineers to work on the grading and drainage design for the motorpool complex.
