Rally worked with the Client to develop a design basis memorandum (DBM) which refined the scope of the project. The team then progressed into detailed engineering and eventually construction support. Key project scope items included pipe rack design, piping layout and tie-in strategy, earthworks and grading improvements, a new bridge crossing, modifications to existing steel structures, and relocation of existing facilities.
The primary pipe rack was designed as a single module that was fabricated offsite. Modularization of the pipe rack reduced overall cost and shifted work hours from the field to a lower-risk shop environment.
Staggered piping tie-ins to connect new rack piping with existing lines were scheduled for turnarounds and other planned outages over a three-year period. Rally collaborated with the Client’s stakeholders to optimize the tie-in plan and produced construction work packages (CWPs) targeted to each tie-in opportunity.
Significant improvements were also made to the groundwater drainage and local power distribution lines in the project area.
