Boulders were encountered up to 15’. The project was originally spec’d with Drilled Shaft Case Piles which could be installed at a rate of 1.5 piles per day and were much more expensive. Furthermore, the cost of spoil removal was cost prohibitive and oil was present in the contaminated groundwater. **SOLUTION:** Rich Anastasio teamed up with IDEAL to present STELCOR Drilled-In Displacement Piles as an alternate on this challenging site. In order to bypass the boulders and rubble in the soils, each pile location was rock drilled with an 18” diameter down-the-hole hammer and then pre-augered to 18’. A 70k drive head was used to install the piles to a depth of 40’. Two full 200-ton load tests were performed using 6 reaction piles each. The full 200-ton load was applied to the 40’ test piles and after the 12 hour hold period, total settlement was approximately six tenths of an inch. Upon initial unload and rebound total settlement was around three tenths of an inch. The first and second load tests showed a net settlement of 0.312” and 0.268” respectively. The production piles were installed at a rate of 8-9 piles per day and 5 on the slowest day. This resulted in a significant cost and time savings with no spoils.
