Last week, the contractor completed installation of the soil anchors at the uphill retaining wall. This week the work shifted to the construction of the downhill stitch pile retaining wall. The downhill retaining wall includes the installation of 36-inch diameter cast-in-drilled-hole reinforced concrete (stitch) piles to depth of approximately 57 feet (total 36). As of end of the day on September 14 the contractor has completed six of the 36 stitch piles and is on track to complete the remaining 30 piles over the next 10 working days (at a rate of 3 piles per day). The Contractor is working long shifts (10 to 12 hour work days) to meet this goal of 3 piles per day. After encountering rocky soils during the drilling of the first pile, the other five were drilled with less resistance. Following installation of the downhill stitch piles the contractor will form and pour the reinforced concrete pile cap beam that will lie on top of the stitch piles. Pictures are shown below.
We will provide project updates and pictures as the project moves forward.
