D.E. Karn

D.E. Karn - SDA Upgrades
Consumers Energy
Location: Hampton Township, MI

The new multi-million dollar upgrade to the Existing D.E. Karn Plant required the installation of approximately 1,000 ea. Augercast Piles ranging in depth from 40’ to 85’, with capacities ranging from 140 to 270 Kips of Compression Force and 70 to 120 Kips of Tension force to resist building loads anticipated upon final completion of the project in 2013. Our contract was a direct contract for the Augercast Piles which was held by Consumers Energy. Augercast Piles were selected due to their ability to be vibrationless during installation, cost advantages over other deep foundation systems & the low headroom piles that needed to be installed inside the building. The scope of services was the installation of augercast piles in and around the existing structures at the plant along with the excavation, soft dig, & protection of existing plant property. The project required that we work 5 or 6 days a week in order to meet the delivery schedule inside & outside of the building. Due to the site conditions, weekly meeting with project managers were held throughout the project, & daily activity meetings with the site superintendent were required. The project included approximately 70,000 lineal foot of 18” Diameter Augercast Piles, and 582,000 Pounds of Resteel Cages & Center Bars. The drill depths were up to 85’ deep. We performed 4 Compression Pile Load Tests, 4 Tension Load Tests, & 2 Lateral Load Tests to verify the differing design loads. The project was started in the Winter of 2011, and is expected to be online in the early part of 2013. Our services were completed on time and within the original schedule & contract value for our work. The soil conditions are typically a mixture of fill material at the surface followed by loose clay, and underlain by rock/sandstone material in the borings.
