Inquiry #5: Bid Item #151 (Minor Concrete - Minor Structure) has a quantity of 215 CY, of which +/-98% is for the Bioretention WQ weirs (spacing as shown on plans and transverse to bioretention flow).

Inquiry #106: Taking the longest timeline from the table in Spec Section 8-1.10B which is 365 working days from Contract Approval and then adding the 120 working days we have to allow for the TSI scope of work, we have 485 working days to complete toll lane work. The contract time is 740 working days. What work is left to be done in the remaining 255 working days except for temporary k-rail removal from the median, final grind and overlay, and permanent striping?
Since the purpose of this project is to construct toll lanes on Highway 80 and the necessary work is concentrated in the median, why is the work on the outside shoulders in Stage 1 included in the timelines shown in the table in Spec Section 8-1.10B?

Inquiry #126: Notes 19, 245, and 296 on the project legend indicate one (1) 144 strand single mode fiber is required along the fiber optic (FO) pathways.

This is not possible with a single 144 strand fiber; two would be required to achieve this. Please confirm if a single (1) or two (2) 144 strand fiber is required, as this would double the amount of fiber and significantly increase the project cost. Examples include:
1) E-11 (mile markers: 575+50, 580+25, and 585+50)

Inquiry #132: In your answers to BI #106 and #107 you refer to Addendum #2 and a revised Special Provision Section 5-1.20G. If you intended to revise the TSI Scope of Work chart, this was not included in Addendum #2. In your answer to BI #106, we don't know what the 328 working days refer to and how this is incorporated into the 740 WD of the contract. In your answer to BI #107, we also don't know what the "Corridor End to End and Disaster Recovery Testing" and its 30 working day window refer to and how this is incorporated into the 740 WD of the contract. Can Caltrans issue a revised SSP Section 5-1.20G and corresponding TSI chart that spells out the specific working days referred to in the answers to BI #106 and #107?

Inquiry #133: 1. In your answers to BI #106 and #107, you refer to 328 WD for TSI work and 30 WD for Corridor End to End Disaster Recovery Testing. The longest time line through the project to complete work at the end of Stage 2 is 365 WD. Are we to assume that we add the 328 WD and the 30 WD to the 365 WD for a total of 723 WD? That would leave 17 WD to complete the final striping and signage in the express lanes.
2. Is the installation of the sign structures, including drilling and installing foundations, and the concrete barrier installation at each sign location included in the 328 WD for TSI work?

Response #2:Please refer to Addendum #4 issued on 12/2/21.
1. For construction staging sequence, refer to Section 8-1.10B. Segments can be vacated by the civil contractor for use by the TSI as soon as the civil work is completed as stated in the Section 8-1.10B. TSI WD for each segment will begin counting as the TSI is given control over that segment as stated in Section 5-1.20G. Section 5-1.20G also states the total number of WD allowed for the TSI over all segments combined.
2. The installation of sign structures, including drilling and installing foundations, and the concrete barrier installation at each sign location are responsibilities of the Civil contractor.

Inquiry #152: It is typical that Caltrans procure all the encroachment permits required prior to contract award due to the long lead time needed to secure the permits. Per section 5-1.20B(3) Caltrans has made it the contractors responsibility to obtain the permits and pay the estimated 11.5% fee of the construction cost for the improvements (Per City of Vacaville). With two separate structures and surface street improvements at Mason and Davis the 11.5% is a significant dollar value. Requiring the contractor to obtain the permits may delay the start of work which is already short based on the time allowed per the table in Section 8-1.10B. We request that Caltrans revise Section 5-1.20B(3) and obtain all the permits required to not delay the start of the contract work.
