The responses to bidder's inquiries, unless incorporated into a formal addendem to the contract, are not a part of the contract and are provided for the bidder's convenience only. In some instances, the question and answer may represent a summary of the matters discussed rather than a word-for-word recitation. The availability or use of information provided in the responses to bidder's inquiries is not to be construed in any way as a waiver of the provisions of Section 2-1.03 of the Standard Specifications or any other provision of the contract, the plans, Standard Specifications or Special Provisions, nor to excuse the contractor from full compliance with those contract requirements. Bidders are cautioned that subsequent responses or contract addenda may affect or vary a response previously given.
Q1) The table on page 180 of the contract Special Provisions lists the 'acceptable earth retaining systems'. The ARES earth retention system as designed and supplied by Tensar International Corporation is listed on the Caltrans website as an approved precast panel system for this type of application. Our system is not listed on this table. As a precast panel system we can comply with both the structural and aesthetic requirements shown in the contract documents. We request that an addendum be issued adding our system to this table.
A1) Addendum for this system will not be issued at this time. Caltrans Traslab prior approval is required for all new products. The prequalification requirements are available at: http://www.dot.ca.gov/hq/esc/Translab/NewProducts/index.htm 1Nov10.

Q48) It is understood that payment for the biologist would be in a lump sum. Monitoring is to occur according to the Natural Resources Protection Plan. Measures within this Plan are based on the permit conditions and other env. documentation. In general, we find that the monitoring tasks are dynamic in nature and difficult to estimate at this time. For instance, if CRF is identified and relocation is necessary, the cost for this service cannot be quantified at this time since it is unknown how large the population could be. USFWS discusses this on pg 16, paragraph 2, of the Biological Opinion. Would Caltrans consider providing an estimated quantity of survey days anticipated or allow for a time and materials not to exceed amount?

Q67) On plan sheet 1045 (Planting and Irrigation Key map) Construction Detail Sheet # 41 (Plan Sheet 222) is referenced at the Russel Road location. On Plan Sheet 1016 (Summary of Quantities Q-15) a 250mm CHDPE conduit is indicated as being shown on Plan Sheet C-41 on the RUSS Line. However, Sheet C-41 does not show Irrigation Crossovers at Russel Road; instead it shows typical Rumble Strip installations. There does not seem to be a Plan Sheet showing the listed Irrigation Crossover on the RUSS line.
A67) Irrigation Crossover construction details for Russell/Espinosa area not included as C-41. Plan sheet added as 222a. Please refer to addendum No. 2, dated November 19, 2010. 22Nov10.

A70) Sheet no. 295 (EC-52). 22Nov10.
Q71) Regarding the culverts to be lined with cured-in-place pipeliners, there are 3 culverts for which no depth, slope or invert elevation information has been provided. Culverts at STA 127+70.740 on the "O" Line, STA 157+43.914 on the "P" Line, and STA 158+51.047 on the "P" Line are not shown on any of the drainage profile drawings, and the cured-in-place pipe liner detail drawing DD-8 (sheet 562) is shown as having "No Scale". Please provide pipe depths in terms of maximum soil cover over the pipe crown, and either pipe slopes or invert elevations at both ends of each pipe for all 3 of the culverts currently missing this information. The depth information is needed for designing the CIPP thickness, since specifications require groundwater to be calculated at half the pipe depth. The slope &/or invert elevation information is needed for determining appropriate cleaning and installation procedures to be used.
A71) Bid according to plans and specifications. If changes are necessary, they will be handled by proposed Contract Change Order. 29Nov10.
Q72) At the prebid meeting, the representative from the Monterey County Transportation agency stated that "prior to award" they would review the list of proposed subcontractors to evaluate if some of the work was being done by subcontractors from the local area. This statement is contrary to any contract requirements or rules governing state highway contracts. In lieu of the fact that a number of the General Contractors bidding this project are from Monterey County, please confirm that they will not be given an advantage over the bidders from outside the county.
A72) There is no change in our process for reviewing bid documents and awarding the contract to the lowest responsive bidder. If TAMC reviews the bid, it would be for informational purposes only. 22Nov10.
Q73) The pre-bid meeting was held 2-weeks prior to the bid date. The intent of the pre-bid meeting was to provide SBE and UDBE subcontractors information about the work, and access to the bidding General Contractors. We have had nuerous complaints from the SBE's and UDBE's that the window of 2-weeks (prebid to bid date) is not enough time for them to understand and bid various portions of the work. A bid date extension would allow the disadvantaged businesses (who attended the meeting) an appropriate amount of time to bid this project, which was the intent of the meeting.
A73) The bid opening is currently scheduled for November 30 and at this time, there is no change in this date. The subcontractors and bidding prime contractors were expected to use the time between the advertising date of October 11, and the bid opening date of November 30 to prepare their bids. The prebid meeting was intended to foster contacts between the bidding prime contractors and UDBE subcontractors. Information about the various portions of work was provided in the list of bid items and Special Provisions that was available at the time the project advertised (October 11). 22Nov10.
Q74) The nearest boring (B13-06) to Abut. 3 on the Crazy Horse Canyon Rd OC bridge shows groundwater at approx. elevation 112.6. This information is confirmed by the Groundwater Monitoring Well table included in the Additional Information Handout in Addendum 1. Abutment 3 is currently designed with 400MM CIDH piles with tips at 108.6 -- 4M below groundwater. Caltrans requires a minimum shaft diameter of 600MM for wet-hole slurry methods. Please advise.
A74) Bid per the current contract bid documents. 23Nov10.
