The Commons Rebuild project entered Phase Three this past month, as Vacri Construction is back on site digging-out trenches for the installation of telecom pipe ducts and utility vaults (the large pre-formed concrete blocks with manhole access). The duct bank run along the western end near Cayuga Street is being worked on right now.
In addition to the duct piping and vaults, NYSEG is installing a new gas main along several of the outside edges of the construction fence to replace the old one. The concrete slab is cut and removed in sections, then several feet of soil is dug out to install the piping. The gas main is not part of Vacri’s contract, but since the gas main is quite old, NYSEG requested to replace it during the same timeframe since the project presents an ideal opportunity to do so. As of now, the concrete is cut, but not yet removed.
