We were tasked with the analyzing the acquired survey data and flow calculations to provide an easy to install and dependable working-solution in a very short timeframe. We began by checking the prepared flow calculations and existing thrust block / piping geometry. MRD modeled the entire vault in Solidworks® CAD and developed a bypass and installation procedure that was to meet the customer capabilities and requirements. Design function and lifting loads were analyzed with FEA software and a complete design package was delivered to the customer. After review, MRD was able to move quickly to the fabrication process.
MRD utilized in-stock heavy profile inflatable seals and in-stock steel, burning, welding, and fabrication resources to quickly fabricate the bypass. Cranes were utilized to attach to load-rated lifting points on the bypass to support the bypass water weight load during installation. The unit was shipped overnight to the customer and was installed immediately. The customer installed the bypass specifically to our installation procedures and were able to begin construction demolition and repair within a day. Work occurred on three shifts over two weeks including the pouring and set-up of critical concrete structures. After successful completion the bypass was removed and the customer was able to move on to the remainder of their construction schedule.
