Inquiry #2: Section 8-1.09 Incentive/Disincentive for Early Completion -- spells out two milestone dates for the project.
Segment A, Sta F 198+00 - F 234+00 >> July 15, 2018
Segment B, Sta FRT 132+00 - F 198+00 >> October 15, 2018
The disincentive penalty amount for the milestones is $ 25,000/day.
The section does not spell out what the anticipated start date will be for the project. This inquiry was brought up by most bidders at the pre-bid conference on November 15th. At the prebid, Caltrans presented a slide in which the start of construction was noted as February of 2018.
For the purposes of scheduling the project in order to determine if the two milestone dates are achievable, what should the bidders assume to be the approval date of the contract? Contracts typically take anywhere from 2 to 4 months to be approved after the date of the bid. How is it possible to bid the project, with the heavy milestone penalties, without a stated start of construction activities date?

Inquiry #11: The special provisions state that this bid must be on a cost+time basis and that the contractors should not bid less than 210 working days and not more than 350 working days. By nature, cost+time basis contracts may include night and day shifts and weekend work. Yet, the department has included provisions (8-1.09 Below) to deduct additional expenses incurred as a result of acceleration. Please identify and itemize these costs so the contractors can be accordingly.

8-1.09 INCENTIVE/DISINCENTIVE FOR EARLY COMPLETION
“At your request, the Department may accelerate its inspection and testing. The Department deducts any additional expenses incurred as a result of the acceleration.

The time limit specified for the completion of the work is considered insufficient to permit completion of the work by working a normal number of hours per day or week on a single shift basis. Should you fail to maintain the progress of the work in conformance with "Progress Schedule (Critical Path Method)" of these special provisions, additional shifts will be required to the extent necessary to ensure that the progress conforms to the above mentioned schedule and that the work will be completed within the time limit specified.

Actions required by the Engineer to perform normal inspection and testing duties will not be considered as contributing to any delay in awarding incentives or to any delay that will require charging disincentives.”

Inquiry #13: 1) Roadway excavation - within the Earthwork quantities chart on Q-3, there does not appear to be an accounting of miscellaneous excavations that will be required for the various Gore Areas; or the 2 ft wide slot (paving section 7) which begins at Sta MMR1 132+63. Is the earthwork chart correct?

2) At the Paving Section 1 areas the grind depth is 0.25'. The existing section is shown as 0.25' AC over the existing PRF, which puts the grind depth at the exact location of the PRF. Typically the depth of cold plane is taken to a level below the PRF which allows for its removal. If the PRF is encountered at the exact depth of cold plane, what is expected in regards to the (e) PRF prior to placing the 0.15' of RHMA?
