Utility Trestle Design

The project scope included designing a mile and half of pipe racks/trestles in an existing facility, by routing miles of wire, cable and pipe across hundreds of acres, with some areas reaching over 80 feet in height.

The selected design approach utilized modularization and off-site fabrication to divide the trestle into 900 truckable modules. These were then transported to and erected on-site to keep the project schedule on track.

The key to our success was placing major material orders early in the design phase and our team’s use of flow diagrams in lieu of P&IDs to support the aggressive schedule.

Other actions included using preliminary calculations and models, reasonable conservatism in developing MTOs for steel, pipe and cable tray orders and formulating unique designs and specifications for plastic pipe.

Despite the intense schedule and design challenges of a project of this magnitude, our team met all key milestones and maintained the project schedule. This was the largest and most technically challenging project Anvil has completed to date.
