7. Section 00800, 1.13, A – We will do our best to submit a barricade plan with our bid, but this will not be the final plan if awarded the project. We understand that the details of final logistics will be worked out with the selected contractor. The intent is to see the logistics approach.

12. Please define working hours for loud work while scheduled events are taking place and when scheduled events are not taking place. Best efforts should be made to schedule loud work on non-event days or at night. These escalators serve the Thomas Murphy Ballroom which often hosts evening/night events so specific scheduling will need to be worked out with the selected firm.

13. Please provide a schedule of known events which this B25/B26 escalator work will impact in year 2024. A copy of the 2024 Event Schedule current as of June 15, 2023 is attached.

1.8 with an alternate for Escalator Monitoring System, but we do not see the section included in the bid documents. Ignore the reference to Section 01030, Alternates.

As it pertains to the monitoring system, the specifications call for a port in the controller 2.6 D 8-9 and what it must do. This port is required to accommodate future installation of a monitoring system.
