Augercast Pile Testing and Construction for a New Library in Castle Rock, Colorado
Hayden Leach, Project Engineer and Phillip Gallet, Senior Engineer - Business Development - Keller North America

 

The construction of a new library in Castle Rock, Colorado required the installation of deep foundation systems to support the building loads. Keller was brought onto the team to discuss alternatives to traditional caissons. Keller has experience with aggregate piers on many of the nearby structures, but ultimately the county wanted a deep foundation system. Augercast piles were selected as the preferred foundation system due to the cost and schedule savings in lieu of drilled caissons.
This presentation will discuss the design, testing and construction of the augercast piles for the library project. The augercast pile installation was completed within the required schedule and half of the original caisson budget. Quality control measures were implemented throughout the construction process to ensure the integrity and performance of the piles. The pile load test results confirmed the design assumptions, and the piles met the required capacity.
This project demonstrates the successful application of augercast piles as a deep foundation system for a new library in Castle Rock, Colorado. The design and testing methodologies presented can be used as a reference for similar projects in the future.
