Devon Tower

GeoSonics/Vibra-Tech has the monitoring technology to help you stand tall, with confidence and stability, allowing your project to tower above the competition.

Holder Construction, based in Atlanta, Georgia and Flintco Construction of Tulsa, Oklahoma were awarded a joint venture to construct a new 54 story, 1.5 million square foot building to house corporate headquarters in Oklahoma City, Oklahoma for Devon Energy, the largest U.S. based independent oil and natural gas producer. In order to construct the tower, two existing parking decks had to be demolished that were in close proximity to other buildings, including the historic Colcord Hotel. The project also required drilling and installation of caissons around the perimeter of the excavation site to support a deep building footprint. Another concern was that the neighboring structures needed to withstand pile driving and other heavy construction activity necessary to build the foundation and support system.

GeoSonics/Vibra-Tech was retained by the project development manager to conduct preconstruction surveys for structures surrounding the site. This service also included installing Re:mote borehole settlement sensors and piezometers to provide measurements of ground settlement near three adjacent structures and monitoring static ground water levels near the site. Re:mote seismographs were placed around the perimeter both outside and inside surrounding structures to provide vibration monitoring data and vibration alarm notification to construction personnel. Potential ground settlement and static ground water level adjacent to the construction of the tower was also monitored. All Re:mote systems were programmed to take measurements every 30 minutes and plot readings on a graph updated and posted to a website every four hours.
