Inquiry |

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 (i.e.design,approval,manufacture) and THEN 30 working days for the on-site work?

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?

This requires 3 weeks allowance for the engineer to review the shoring drawings. This represents 15 working days of the 30 allowable. Can additional time be added to the project to compensate for this review time?
