Case Study

Pipe Bridge Project

Challenge:

A refinery client needed design support to reroute eighteen (18) pipe runs that were laid underneath 127th Street. They needed to find a solution that would permit them to maintain and inspect the piping in accordance with API 570.

Solution:

After considering various options with the client, Valdes prepared preliminary engineering to develop a Class II total installed costs (TIC) estimate, followed by detail engineering to support fabrication and installation of a bridge to run the piping over the street. Valdes performed 3D modeling to generate a piping layout and routing, along with associated structural components (foundations, structural, and supports) while coordinating with client construction and operations representatives throughout the design process.

Impact:

Valdes ultimately provided deliverables to have the system fabricated and built. They included the electrical, instrumentation and controls construction scope of work and material takeoff; various packages, including one for structural modular construction, field steel construction, turnaround piping construction and turnaround piping tie-ins; plans for foundation location, composite cable and conduit, and revised grounding; and drawings for revised conduit details, existing lighting and revised existing lighting panel. The final product provided the client a solution to perform API 570 piping inspections.
