Inquiry #16: The Asbestos and Lead-Containing Paint Survey Report provided in the Informational Handout states no paint samples were taken to identify Lead Containing Paint. The recommendation is that existing signage and traffic striping be treated as lead-containing for purposes of the project, and safety/design/handling to be included of LCP be in bidders pricing. For the signage and traffic striping LCP efforts, what bid items shall those costs be included in?
Also, the report does not state locations or survey results taken from the Paintersville Bridge where structural steel rehab is to be performed on the project. Shall bidders assume the Paintersville bridge has lead containing paint? Shall bidders included complete Cal/OSHA compliance for isolating, containing, and handling prior to and during the rehabilitation work? Have the permitting agencies been notified of the potential lead based paint mitigation work over water? What bid items do contractors include the costs, which may be significant, for the LCP mitigation efforts on the Paintersville Bridge?
Inquiry submitted 07/17/2019
Response #1:
(#16)-There is no traffic stripe removal item in the plans or estimate. Therefore, you don't have to include the cost of lead based striping removal in your bid. Your attention is directed to section 5-1.02, "CONTRACT COMPONENTS" for information regarding governing ranking of Contract parts.

Inquiry #17: Section 49-3.01B(2) Mass Concrete. The specification states CIP concrete piles greater than 8 feet are Mass Concrete. The CIDH shafts on the Paintersville Bridge, below the steel casing, are 96" diameter. Please confirm they are not to be considered Mass Concrete.
Also, the project contains zones of CIDH sections greater than 8 feet, the 108" zone encased in a permanent steel casing. Subgrade concrete is not typically considered mass concrete due to subgrade installation and the casing protection protects from thermal cracking exposure, these areas are fully cased in this zone. Will the 108" zone be considered mass concrete per the specifications.
Is temperature control plan required for the CIDH concrete? Will a previously approved Caltrans shaft mix qualify, or is a new mix design and testing required? Should contractors plan for cooling pipes? If temperature monitoring devices are required for the shafts, where should they be located? What bid item shall contractors put the price of mix designs, thermal control plans, and related mass concrete efforts in?
If the 108" zone is mass concrete, is there an optional construction joint bidders can utilize to install normal concrete in the 96" shaft at the bottom of the permanent casing, and then convert to the mass concrete?

Inquiry #26: For the Paintersville Bridge large shaft foundations, the permits discuss and allow a Barge with driven pile to keep the barge in place yet allow for water level fluctuations, described like a normal spud barge but with driven pile instead of gravity set pile. The permanent steel casing will be driven using vibrator and impact hammers (or other) and the CIDH work requires drilling methods. Regardless of how the foundations are installed, whether performed using a drill under slurry or a rotator/oscillator system, in order to construct these shafts it will require a template platform over the hole using driven pile to support the permanent casing for elevation and alignment. Will a fixed platform be allowed over the shafts for the Paintersville Bridge?

The special provision for this work on page 69 calls for corrugated steel pipe complying with Standard Specification 66. It is not practical to split corrugated pipe and splice it in the field because the residual stresses in the spiral pipe will twist the halves when cut. No detail is provided on the plans to do this either. The proper way to supply casings for field assembly is with plate pipe per Standard Specification 67.

Inquiry #30: Special Provision 10-1.03 states "No in-water work is allowed at Mokelumne River Bridge ESL from October 16 to July 14. No in-water work is allowed at Paintersville Bridge ESL from November 1 to June 30". This is in agreement of the Caltrans Structural Engineer determination.
In the Information Handout Exhibit A, a letter from Fish and Wildlife Service (Oct 06, 2016, pg 2) states "The National Marine Fisheries Service (NMFS) recommended in-water work for avoiding effects to listed salmonids and green sturgeon in the project action area segments of the Mokelumne River and Sacramento River is between July 1 and September 30th. The Service's recommended in-water work window for minimizing effects to delta smelt tin the project action area segments of the Mokelumne River and Sacramento River is between August 1st and November 30th." Based off this language and if we must apply both standards for salmonids and delta smelt, by following the most stringent dates and complying with all the permit language, in-water work for both bridges is only allowed between August 1st to September 30th. Contrary to the Caltrans Structural Engineer determination of 60 working days over 3 months, the contractor has approximately 40 days over 2 months to complete this work.
Does the special provision take precedence over the language in the Fish and Wildlife Service letter (Oct 06 2016)?
Inquiry submitted 07/24/2019

Inquiry #32: Special Provision 8-1.04C states job site activities cannot start prior to the 55th day after contract approval with exceptions. Is this Calendar Days?
Assuming the project bids on August 1st, and there is a minimum 10 day award period, the 55th day after contract approval is October 14th. This date is outside the permitted In-water work windows meaning no in-water work on either Bridge will occur until August of 2020. Further, this date is past the garter snake window where No ground disturbance can occur, meaning the Mokelumne Bridge work cannot begin until May 1, 2020. Please confirm these assumptions and that in-water work for both bridges cannot start until August 2020, and Mokelumne Bridge work cannot begin until May1, 2020.
