NGE-TFT provided engineering design and construction inspection to two separate phases of construction at Halliburton’s Prudhoe Bay facility in Deadhorse, Alaska. NGE-TFT provided recommendations for freeze-back pile foundations for the proposed Nitrogen Plant, Sperry Shop, and Truck Maintenance facilities constructed on-site. NGE-TFT also provided on-site inspection of the pile installation activities, including logging of excess ice in each pile pilot hole, observation of slurry activities, and thermal monitoring of slurry freeze-back. The on-site inspection was critical in providing real-time engineering design modifications based on the amount of ice encountered at each pile site. Thermal monitoring of the slurried piles also allowed for more accurate determinations of pile loading.
NGE-TFT was contracted to provide a geotechnical evaluation for the design of the proposed health center and associated parking area. Final geotechnical engineering recommendations for the site were developed based on preliminary subsurface explorations conducted at the site, which identified the presence of permafrost within the proposed building footprint and resulted in a re-configuration of the site design. NGE-TFT also provided construction oversight during the foundation construction and cut/fill activities at the site.
Provided preliminary geotechnical analysis and recommendations on Slope Stability for 500 home development.
