Title
Consider Authorizing The City Manager To Approve Contract Amendment #1 With Bridgefarmer And Associates For Design Modifications For The Railroad Quiet Zone Phase II Project In An Amount Of $11,500.00, For A Revised Contract Amount Not To Exceed $120,500.00.
Body

City Council authorized the original quiet zone engineering design contract on March 20, 2012. After the project went out for construction bids, the BNSF Railway required a crash barrier for their equipment on the Josey Lane median, which resulted in an unforeseen redesign effort. The barrier was later redesigned to compensate for BNSF placing their equipment in a location different than what the original design established. A retaining wall was also redesigned as a consequence of the rail equipment placement. The manufacturer's shop drawings for pedestrian safety hand-rails required significant review and design efforts. Other design modifications were undertaken by the consultant during construction to compensate for field conditions, which made a positive contribution to the overall timeline and quality of the project.
FINANCIAL IMPLICATIONS:
The original amount of the railroad quiet zone phase II engineering contract is $109,000.00. The proposed amendment is for $11,500.00 (a 10.5% increase). Funding is available in the Traffic Consolidated - Railroad Quiet Zone project account.
