Marathon Oil Tower Façade Condition Assessment
Walter P Moore performed a comprehensive assessment of the façade system components at the 42-story Class A Marathon Oil Tower building. This includes arms-length observation of the building envelope at over 56 drops using a permanent façade access building management unit (BMU) rigged from the roof level. We are reviewing the granite cladding and clip panel supports, sealants, gaskets, window frames, insulated glass units, flashings, and integrated continuous stabilization anchors used during operation of the BMU. Nondestructive and minimally invasive testing are being performed using a borescope, infrared camera, Delmhorst moisture meter, and frost point testing. We are also analyzing the original design and as-built construction of the exterior wall and window systems, as well as diagnosing the cause of potential moisture infiltration (rainwater, condensation of moist air, vapor diffusion) through the building envelope.
