Question: How will the water line be lower without taking customers out of service or providing temporary water to those customers? Answer: Plan sheet 16 (DR-402) has been revised to include in the bid tabs the installation of a 6” gate valve that will isolate the 6” water line during the lowering extension while keeping customers in service. The waterline will not be required to be tested, however close observation of installation methods used will be conducted to ensure proper, safe techniques are used to ensure the high water quality delivery. 2. Question: Is there a line item to pay for backfill of existing box removal? Answer: Yes, Line item #13 – Embankment (CY) is the intended pay item for this task. 3. Question: Is the City receptive to entertaining alternative CBC designs, i.e. precast sections? Answer: At this point the proposed CBC design has been reviewed and approved by the Arthur Ditch company. Any redesign would have to be drafted and reviewed by the Arthur Ditch on call Engineer. This is not typically a timely effort and would likely exceed the contract duration. The City of Fort Collins possesses no authority over the Arthur Ditch company and they in turn may not entertain any revisions to the plan set within the effective contract timeframe. 4. Clarification: Line item #16 – Structure Excavation (CY) has been increased to 1,384 CY from 850 CY.
