Construction crews continue work on the East Retaining Wall; removing formwork and backfilling the concrete wall in preparation of staining the concrete "stones" to match that of existing material in the area. The backfill activity is a timely operation. Crews install 8" layers of two different types of material: one to provide structural support and another to allow the wall to be relieved of pressures from accumulating water. Each layer is mechanical compacted and then test to ensure proper density is achieved. The operation also includes the installation of waterproofing material so that stormwater does not seep provided joints in the wall.
Construction has also begun on a much smaller retaining wall on the east side of the project along the ramp to Beach Drive. The existing retaining wall is not structural sound and therefore will be removed and replaced. The replacement retaining wall will utilize existing, salvaged stone from the project.
