Q7) Please reconsider your responses to pre bid questions # 1 and #2. Your design requires the removal of existing safety rail. Your work hour and lane closure restrictions limit the available time for the performance of removal, minor concrete installation and cure, and rail installations. All temporary K Rail and / or crash attenuators are to comply with your contract requirements. Therefore YOU must provide the appropriate design quantification and contract pay items to facilitate that design.

It seems that this hour should be marked as "2" as are the 4 hours earlier and 6 hours after. Please confirm this interpretation.

A8) There appears to be a typographical error. This hour should be marked as "2". 8Mar11.
