Additional Backup Information:
The Rock Harbour Force Main project consists of approximately 4,500 linear feet of a new High-Density Polyethylene force main installed from Rock Harbour Lift Station to the existing ductile iron force main on Vista Parke Drive. The alignment parallels Rock Harbour Drive, crosses FM 620, parallels Wilson Park Avenue, turns south on Woodbay Parke Drive, then connects to the existing Four Points #2 16-inch force main. The proposed force main across RM 620 will be installed via trenchless construction while the remaining force main will be open cut. There will also be 100 linear feet of ductile iron force main installed via open-cut across Wilson Parke Avenue at 12132 1/2 Wilson Parke Avenue. Also included is the demolition of Four Points #2 Lift Station and abandonment of 2,540 linear feet of gravity main and associated manholes. Lastly, the project includes the installation of the final fourth pump at the Rock Harbour Lift Station and changing the impellers on the existing three pumps.
At the beginning of construction, Right of Way Management identified safety gaps in the approved Traffic Control Plan. The gaps required significant plan redesign that has increased the cost and scope of the Traffic Control Plan. Additionally, the lift station and force main was previously built and maintained by the Northwest Austin Municipal Utility District #1. During construction discrepancies between the as-built drawings and actual below ground field conditions were discovered, resulting in redesign and Traffic control plan changes.
This additional contingency funding will allow for the expeditious processing of any change orders necessary due to conditions that were unforeseen at the time of bidding and presented later during construction. A contingency is an additional amount of money added to the construction budget to cover unforeseen construction costs associated with the project. By authorizing the additional contingency funding, Council is authorizing any change orders within the contingency amount.
There will be continued lane closures in this area since much of the work is located in the right-of-way. There are signs and barricades to guide the traveling public.
This project is located within zip code 78726 (District 10).
