1. Question: Please consider clarifying what will be required for storm water pollution control measures for this project. Because the project involves only ac overlay & shoulder rock performed in dry summer weather, one would expect no measures such as silt fence or straw waddles would need to be installed. However, with the presence of roadside ditches and rice irrigation at the job location, and the inclusion of the totally wide open Water Pollution Control specification on pages SPD 21 to SPD 31, it is conceivable the County or other agency could require silt fence or straw waddle the entire length, both sides. Depending on specifics, this could add an additional $20,000 to $50,000 to a contractor’s bid
Answer: The County has provided a list of water pollution control measures. It is up to the Contractor to decide which measures and at what quantities these measures will be utilized so that the water pollution control work shall be in compliance to the applicable requirements.
1. Question: Is Railroad Liability Insurance going to be required for this project since work will be done within the Union Pacific Right of Way? There is nothing in the specs concerning whether the County or the Contractor will pay the costs necessary for the Union Pacific Rail Road Flaggers that will be required for work within the railroad Right of Way. Please advise if the Contractor is expected to pay these costs or if the County will be paying.
Answer: Flagging within the Railroad right of way will be procured for the contractor at no addition cost.
