Upon arriving on site, we met with Howard Clark, to discuss the objective of the day. The contractor planned to install multiple pin piles, across the exterior of the building, before the contractor continued to install brackets and prepare the site to proceed with the installation of pin piles. The contractor used a 140-pound hammer and a 2-inch diameter, 5 foot 3 inch long, steel pin pile, which was driven through an opening within the bracket. Upon completing the installation of the pin pile, the brackets will be secured and used to support the existing foundation. We observed the contractor install the following piles, identified per their label according to the plans: Pin Pile ID Embedded Depth 1 13 4 15 8 15 14 15 20* 10 23* 5 * Encountered an obstacle during installation and did not meet refusal. It was recommended that the pile be relocated to avoid the obstacle. We will continue to monitor the site on a part-time basis, and are available for additional consultation if requested.

Upon arrival to the site, we met with underpinning contractors from Advanced Foundation Supports, LLC. The pin piles consisted of 2-inch diameter, schedule 80, galvanized steel, which were cut into 5.3-foot lengths and connected with steel internal slip couplers. We monitored as the pin piles were driven with a 140-pound pneumatic post -driver to a refusal criterion of one inch or less of vertical movement in sixty seconds of continuous driving. Pin piles observed to be installed today were driven to a dead stop at one inch or less of vertical movement in 300 seconds of continuous driving. The depths to refusal and corresponding pile numbers are listed in the table below. The depths are measured from the top of the structural bracket placed at the base of the foundation footing.

We recommended the underpinning contractors confirm relocation plans, or other method to reach refusal in native soils, with the structural engineer, per provided plans. We have been providing monitoring of pile installation on a full-time basis. Our findings and conclusions are based on specific observations made while on site. It is our opinion that the pin piles we observed today were installed in accordance with the project plans and should support the planned loads. We understand that the contractors will continue to drive exterior piles the next business day, and will continue to monitor the installation of underpinning at the site.

Upon arrival to the site, we met with underpinning contractors from Advanced Foundation Supports, LLC. The pin piles consisted of 2-inch diameter, schedule 80, galvanized steel, which were cut into 5.3-foot lengths and connected with steel internal slip couplers. We monitored as the pin piles were driven with a 140-pound pneumatic post -driver to a refusal criterion of one inch or less of vertical movement in sixty seconds of continuous driving. Pin piles observed to be installed today were driven to a complete stop or at least one inch or less of vertical movement in 60 seconds of continuous driving. The depths to refusal and corresponding pile numbers are listed in the table below. The depths are measured from the top of the foundation footing.
