Inquiry #3: From Sta. 532+52.8 to 555+02.9 the plans call for a Drainage System 6 to be constructed in median of Route 241. The traffic handling plans do not address this scope specifically. Our questions are as follows:
Will the shoulder closures be allowed during this work so that we can plate our trenches?
Will trench plates be allowed on the shoulder or on the mainline after the Route is opened to traffic?
Will the State allow and pay for the use of K-rail in this area to protect the work?
Will the State consider any full closure to complete this drainage system?
For this drainage system, can the State confirm that the existing barrier is not in conflict with the proposed drainage system?

Inquiry #7: Can the State confirm that the excavation required to complete bid item 36 (6" perforated plastic pipe underdrain) is paid for in bid item 22, trench excavation?
Trench excavation is measured and paid by the CY? If soils condition require the Contractor to dig a wider trench, or for safety reasons the Contractor uses a wider trench, will the State confirm that the additional excavation will be paid at the unit price for Trench excavation, bid item 22?
Inquiry submitted 09/01/2021

Inquiry #8: Per the lane closure charts there are no full freeway closures allowed. When we grind and pave the variable asphalt level courses we will have elevation differentials at the lane lines, which is a safety concern. In order to pave the level courses safely we would need full freeway closures in order to pave the full width of the freeway each shift. Please advise.
Inquiry submitted 09/01/2021
Response #1:Pending
Response posted 09/01/2021
Response #2:"Refer to LRC in SSPs, no full closures are permitted. Uneven pavement may result, but appropriate safety standards need to be followed in concurrence with the Resident Engineer."

Inquiry #11: Per addendum # 2, pavement section note # 2 has been revised to show a .20' cold mill with the installation of a variable HMA up to 1.15'. This would mean that there will be a longitudinal lane elevation differential of up to .95'. Per Caltrans safety guidelines it is physically impossible to install this pavement section without a full closure of the freeway. Per addendum # 2 there have been no adjustments to the lane closure charts. Please advise how Caltrans plans on installing this pavement section with the current lane requirements.
Inquiry submitted 10/01/2021
Response #1:Pending

Inquiry #17: Regarding Bid Item 36 (addendum 2), it is difficult to tell from the plans if the proposed drain is located beneath the existing pavement on the shoulder or in an unpaved area of the shoulder. To assist us in preparing the estimate can the State explain what percent of the drain is located beneath a paved area of the shoulder? Our concern is how much saw cutting and trench restoration will be required?
