Sea Wall Installation
Work on the project began in the summer of 2011. Removal of the existing wall was followed by the excavation of a trench for a footing. Ocean Avenue remained open and untouched during the construction of the new wall. The wall was completed in mid-August, just before tropical storm Irene visited the Rhode Island coast. The wall had a second major test with the arrival of Hurricane Sandy in October of 2012. The use of the large wet-cast ReCon Block in combination with Tensar® grids and ArmorLoc hard armor resulted in a unique, cost effective, and construction efficient design that is now standing up to the pounding that the open Atlantic Ocean constantly delivers.

Underground Detention System
Another concept evaluated was the use of 48” diameter HDPE (a competing product), which uses an expensive manifold design, and a larger footprint with more cover than required by Precast Concrete Chambers to maintain H-20 Loading. Using precast the contractor was able to reduce the cost of the underground system as well as complete the project quicker by using precast concrete galleys. In addition, the contractor was able to drive site equipment over the chambers without the need of bringing the site up to final grade. The Precast Concrete Galley system had an overall footprint 15% smaller than the HDPE designed saving stone, excavation and backfill as well as time; while still meeting the designed storage capacity required.
