BESTCCLS was hired by Washington Group International to provide Geomorphic Design Staking at the Centralia Coal Mine Reclamation Project. We were provided drainage parameters, such as maximum acreage per alluvial, maximum slope, and drawings with 10’ contours. From this information, we built digital terrain maps that we uploaded in our GPS unit, so that we could set cut/fill stakes for the earth movers. Adjustments to our DTM were constant—due to the need to balance import/export as much as possible. We also designed and staked boundary drainage and verified volumes of stockpiles with less than solid bases.
To assist in the successful completion of the Beacon Hill Project, Obayashi Corporation hired BESTCCLS. One of our key responsibilities included the control and layout of most of the poured in-place concrete inside and outside of the tunnel. Other daily duties for BESTCCLS on this project were to provide alignment of track, elevation of track sections and station control. Because this project was CAD intensive, our standard operation procedures identified conflicts and discrepancies. In turn, we then worked closely with the engineering staff to find resolution. That intense troubleshooting helped minimize impact to the project’s critical path. It is just one example of our Value Engineering at work.
When the workload on the Microsoft Redmond Campus Project became less than necessary to warrant full-time staff, MA Mortenson chose to hire BESTCCLS to support their direct hire surveyors. They trusted the balance of the project with us for completion. In addition to utilizing our conventional survey techniques, we employed Imaging/Scanning equipment for as-built shear walls on Bldg. 96. BESTCCLS was able to determine the relative deviation from plan of walls 70 feet high without leaving the ground. This, and the fact that we completed the scanning of 8 walls on a 1’ grid in 9 hours, is a strong example of the benefits made available by using this equipment. It reduced costs for our customers and curtailed potential hazardous exposure to our employees.
Currently, BESTCCLS is working with Turner Construction Company to build one of the largest rental car facilities in the United States. The physical size of this site was an ideal opportunity for the use of our GPS/RTK capabilities during the early civil stages. Then, once the project was out of the ground, BESTCCLS used conventional techniques and equipment to ensure the best work. Also, BESTCCLS supports the various crafts and subcontractors with grid control and layout. Our CAD Team has identified scores of potential conflicts, authored numerous RFI’s, and shared their knowledge and professional points of view directly with the owner’s engineering staff.
