Bridge Design for a Petroleum Refinery

Key Features

  • Designed several vehicular bridges with weight capacities ranging from 65,000-85,000 pounds
  • Vehicular bridges constructed with modular pre-cast decking
  • Manway bridge designs also provided to allow foot traffic across refinery piping
  • Accounted for the effects of new design on spill containment requirements
  • Provided construction management and Owner’s Representative services

EarthFax designed several vehicular- and foot-traffic bridges for a petroleum refinery to assist with its goal of exposing all existing underground product pipe lines while providing continued access over these pipe lines where needed.  The intent of the project was to reduce the potential for pipe line product releases to the environment, thereby increasing safety, efficiency, and profitability at the facility.

Following the performance of required geotechnical investigations, we designed cast-in-place footings and modular, pre-cast concrete decking to permit flexibility and cost efficiency in the design and construction process.  For bridges that will carry vehicular traffic, our designs accounted for expected loads typical of refinery traffic, including haul trucks, cranes, and heavy equipment.

We also designed several steel grate walkways for foot traffic across the pipe ways.  These were installed to replace portions of earthen berms that currently serve as crossings over various pipe ways.  Many of these berms were an integral part of spill containment structures that exist in tank field areas of the refinery. Where portions of these berms were scheduled to be removed to expose pipes, we designed concrete walls to preserve the required storage capacity of the spill containment structures.

EarthFax served as the Owner's Representative for this project, providing project management and construction inspection services.  This work was conducted under a tight timetable to minimize impacts to the facility.
