Project: Elevated Pipe Rack

Location: Illinois

Project Scope: INGENII’s engineers performed all structural engineering for the design of a 1000 foot long pipe rack over an existing pipeway at a major Midwest refinery. Design criteria required that supports for the new structure be located so as not to interfere with the numerous existing pipes and valve access platforms. The structure was a combination of longitudinal braced frame and lateral rigid frames with clear spans up to forty feet. The design was accomplished utilizing three-dimensional structural engineering software in order to accurately account for the large thermal movement of the structure, and to optimize the steel framing tonnage due to the large number of unique rigid frames. The design of all foundations and structural steel framing was completed in a two month period to meet an aggressive construction schedule.
