Excavation Support and Micropile Underpinning in Vail, Colorado
This case history describes the design and installation of excavation support and micropile underpinning for a building expansion and renovation project in Vail, Colorado. Local regulations required the building be preserved, thus leading to a new structure that was built both above and below the existing structure. A combination of soil nails and micropiles were needed to support the variety of earth and structural loading conditions that this project created. Installing the micropiles proved to be more difficult than originally anticipated. Low overhead clearances and the tight corners made it extremely difficult to maneuver to the planned drilling locations. Additionally, there were old foundations and footings that were not discovered until the first attempt at drilling which made our initial planned drilling method impossible. In order to adapt to the changed conditions, the method of drilling the micropiles had to be modified a couple of times. With each new method that attempted, more was learned about what worked the best until a system was identified that enabled the installation of the micropiles at the planned locations.
