Location: Westbrook, ME
Owner: Idexx Labratories
Client: PC Construction
Scope of Work
- Installation of approximately 14,700 LF of HP10x42 and HP12x53 piling to support the foundation of the East Building Expansion.
Proximity to existing buildings was a primary concern prior to commencing work on this project. More specifically, the transfer of vibrations to the existing labs from construction activities was a major concern of the project’s owner. This facility utilizes many scientific processes that are highly sensitive to vibration.
In an affort to minimize the risk of vibration transfer, we pre-augered all of the piles that were installed within 100 feet of existing buildings. The depth of the pre-augering was dictated by the soil conditions. Once a hole was pre-augered, we were to place a pile into the hole and drive it with an impact hammer.
This project was somewhat unique in that it required a Static Pile Load Test in addition to a dynamic pile testing program. The static test consisted of stacking 248 tons of concrete blocks and steel piling on top of the test pile to reach the required test load.
