Marathon Oil Headquarters
A 16-story building and 7-story parking garage were constructed to support the relocation of Marathon Oil’s headquarters. Located on a 3.4-acre site, the new headquarters is in a more central location for employees. Langan completed a Phase I Environmental Site Assessment, performed a geotechnical field investigation to explore subsurface conditions, evaluated foundation support alternatives, and provided recommendations for foundations and other geotechnical-related aspects. We also performed a finite element method analysis to estimate settlements and equivalent springs used in the structural analysis of the office building, which is supported on a shallow foundation system consisting of a core mat and spread footings.
