A compressor station in the Rockies needed a full turnkey helical pile foundation solution. TorcSill engineered, manufactured and installed 400 piles to support this station.
Geotechnical information indicated a shallow water table ranging from six feet to 22 feet across location, and the original foundation design specified 30-inch drilled piers installed to 30-feet deep. This approach would have required expensive and timely dewatering and casing solutions, significantly impacting the owner's construction schedule and costs due to additional construction equipment.
Employing a thorough value-engineering approach, ToreSill's design accounted for every foundation on location, and ranged in pile diameters from 3-inch square tubular material for pipe supports and skid equipment to 24-inch pipe piles supporting high axial and lateral loads and large process equipment.
Further adding value, all pile-to-equipment interface connections were in-house designed as steel-to-steel, eliminating the need for concrete as a structural material, thereby improving schedule, reducing safety risks, minimizing environmental impacts and reducing costs.
Capitalizing on a national operations footprint, TorcSill mobilized its Construction Services TEAM from the nearest of its 13 Districts, less than 40 miles away. This proved invaluable as the scope of work saw continued changes and
TorcSill assumed turnkey responsibility for 1,150 piles encompassing every foundation on this gas plant, delivering significant time and costs savings by carefully designing all the steel connection detail. Whether installing two piles or 200 at a time, TorcSill's in-basin Operations presence provided for quick and inexpensive mobilization throughout the entirety of the months-long foundation construction process.
TorcSill provided a foundation solution that bypassed the existing pier, utilizing steel frames connected to multiple helical piles.
