Inquiry No.
Plan Sheet / Specification Reference=GENERAL

The 30 working days allowed for the job seems adequate for actual construction, however the design, shop drawing approval, and manufacturing period could easily consume the entire 30 working days and then some.  Why not allow an advance period for the preliminaries (,approval,manufacture) and THEN 30 working days for the on-site work?

  • See Addendum No. 2.
Plan Sheet / Specification Reference=GENERAL

The traffic control plans seem to give no option other than full-time, 24 hours per day, 7 days per week, coverage with at least 2 on-site flaggers during construction when only one lane of traffic is possible. Was there any intent to allow a portable traffic light regulating time periods of each direction of traffic flow?

  • No. At a minimum two flaggers shall be provided at all times with no exception.
