Thrasher Foundation Repair Case Studies: Addition of a Mezzanine On New Construction For Commercial - Piering
In addition to all services we provide to residential customers, Thrasher provides specialized commercial services for existing and new construction.
This was a new construction project for an expansion at Garmin International Industries.
In conjunction with general contractor JE Dunn, Thrasher worked on the addition of a mezzanine to expand administrative space in Garmin's existing building. To support the expansion's weight, Thrasher installed new interior load-bearing columns and added weight capacity (WC), or working load (WL), to existing columns. Also, we strengthened and underpinned the affected perimeter foundation and exterior columns.
Thrasher completed the first of 2 phases of this project within a relatively tight production schedule. In approximately 30 days, 145 piers were installed.
Thrasher installed 14 new interior columns. Each column required a Working Capacity of 120,000 psi. To achieve this, three helical pulldown micropiles were installed to create the individual columns with a combined capacity of 120,000 psi. Each micropile, or helical pier, had a Working Capacity of 40,000 psi.
Fourteen existing interior columns needed an additional 160,000 psi Working Capacity. Thrasher installed three helical piers around each current column, thereby increasing the working load capacity.
Six new exterior columns, each of which needed an additional working capacity of 120,000 psi, were also installed. Three resistance piers with a Working Capacity of 42,000 psi each were installed to every column. A new supplemental footing was added to the existing foundation and underpinned with the three piers. Eight existing columns needed an additional Working Capacity of 150,000 psi, which was met by installing three resistance piers, each with 55,000 psi working capacity.
Six helical piers were installed to support an elevator shaft in the building.
Thirteen resistance piers were installed at the perimeter to underpin the affected foundation.
When the project was completed, Thrasher Foundation Repair had installed 145 piers in less than 30 working days. All this work was done in conjunction with and coordination with other contractors on-site, to minimize disruption to the regular working hours of Garmin.
