The following was observed. The UTS representative met with Mr. Bob Levesque of Fulcrum (GC) and Mr. Donny Taranto of Pitt Pipeline (site contractor). The UTS representative observed the site contractor excavating perimeter footings for building #2. The site contractor exposed the tops of the previously installed grouted concrete columns (GCC) at the bottom of the footing excavations. During the footing excavations groundwater began weeping into the excavations with some areas containing as much as 10 inches of standing water. Due to the standing water the subgrade was not able to be compacted but rather it was heeled with the excavator bucket. The footing excavation spanned along the northern perimeter and extended south to column line 18. See attached sketch. The footing excavation was about 3 to 4 feet deep and extended through previously placed Structural Fill and existing clay fill. The two materials were separated to re-use the Structural Fill as backfill within the building footprint. Woven geotextile fabric was used over the bottom of the footing excavation and then covered with 6 to 10 inches of 3/4 inch crushed stone. The UTS representative informed the site contractor and GC that the use of non-woven geotextile fabric is indicated on the design drawings. The UTS representative suggested that this change be brought to the geopier designer's attention for review.
