X The stated performance period is Sept 3, 2019 to April 17, 2020. However, no onsite work is to be done between Novemer 12 thru March 16. Work also stated to be complete by Oct 30, 2019 on Pohono and Happy Isle Bridges. Is the plan for work on the other two sites to be concurrent with these sites and the time after March 16? Or is the work on the other two sites to just happen between March 16 and April 17, 2020. Please clarify on intent.

Does this(the contract) imply that Pohono and Happy Isles Bridge be completed between the NTP in September and the end of October. And all other work must be completed by November 12? These timelines do not appear supportable with materials timelines.

No. Complete all work for Pohono and Happy Isles Bridges by October 30, 2019.

Complete the entire work ready for use not later than the Fixed completion date. Be aware of the winter suspension listed in Subsection 108.01. An amendment will be issued shortly modifying work allowed during winter suspension.

In the repair aluminum rail line item (55601‐

040) it would appear that it would sense that this item would be a lump sum in lieu of being based off a lineal footage since only splices and sections are being replaced.

On sheet RGB3127‐B in the estimate chart it says that note 3 regarding the replacement of the asphalt is part of item (55601‐040).

However it seems that this work has more do with item 55603‐1000 remove and reset bridge railing. Please confirm whether the plans are correct or not.

The removal and replacement of asphalt on El Capitan Bridge is a subsidiary item of work on El Capitan Bridge under Section

556. Bid accordingly.
