Inquiry #11: Section B-B shown on Stage Construction and Traffic Handling Plan Sheet SC-100 (Stage 5, Phase 1) shows the No. 1 NB Traffic Lane on the Southbound side. The No. 1 NB Traffic Lane on the SB side is 12’ wide with a variable shoulder. The variable shoulder is 2.3’-13.0’. Can this No. 1 NB Traffic lane be shifted closer to the median barrier and away from the K Rail that is dividing the No. 1 SB and No. 1 NB lanes of Traffic. This would eliminate the need to stake the K Rail as shown in standard plan sheet T3B.

The same scenario applies to Section C-C shown on Sheet SC-101, Section E-E shown on Sheet SC-104, Section F-F shown on sheet SC-105, Section G-G shown on Sheet SC-107, Section H-H shown on Sheet SC-108 and Section J-J shown on Sheet SC-100.

Inquiry #18: More than One Million customers lost power in deliberate PG&E blackouts aimed at mitigating the risk of wind-damaged equipment sparking wildfires over the weekend and more power outages are expected this week.

Our office, field operations and day-to-day business operations are being heavily impacted by the power shutdowns. In addition, our subcontractors and suppliers are feeling the same negative effects. We are requesting that the bid opening be postponed for a minimum of one to two weeks due to the time lost with the intentional PG&E's power shutoffs.

Inquiry #19: Page 68 of the plans shows the requirement that the cobble be stained three different colors and NOT to stain the grout. This would be hugely expensive and would require someone to hand apply stain to each cable and somehow stop stain from getting on the grout. Would an alternative product, like Natina, be allowed? Natina would be applied to the entire area (both grout and cobble) and would create natural color variations since the product reacts with the cobbles and concrete grout differently. Natina does not produce gray tones so this part of the requirement would not be possible. This would be much more efficient and would cost substantially less money. Individually staining cobbles, unless there is something I don't know, would likely cost hundreds of thousands of dollars and stains fade over time from sun exposure so the finished product will not be that way for long.

Inquiry #20: The Stage Construction and Traffic Handling Plans General Staging Concepts in Stage 2 show partial construction of the median shoulder on the South Bound Side of the new Concrete Barrier (see "Stage 2" Detail on Sheet 208/528). Similar Detail is shown Sheet 231/528 in "Section A-A".

There is a clear overlap in work zones in Stage 2 and Stage 3 (see "Stage 3" Detail on Sheet 209/528). It would appear that the contractors are required to build the SB median shoulder partially in Stage 2 and then finish said median shoulder in Stage 3.

What is the intent of this multi-layered phased construction?

Specifically, why is the median shoulder work is on the SB side of the Barrier shown to be constructed partially in Stage 2 and then finished in Stage 3? The notes and special provisions are silent regarding this matter.

Inquiry submitted 11/04/2019

Response #1:Your inquiry has been submitted for review
Response posted 11/05/2019


Response #2:An overlap in work zones regarding stages 2 and 3 would be normal as far as earthwork operations are concerned.

Refer to the Typical Cross Sections X-1 through X-9. Note that the roadway surface on each side of the concrete median barrier is sometimes uneven. Also note that the high side or upper roadbed structural section changes from one side of the concrete median barrier to the other side at several locations throughout the length of the project. Similarly, the lower roadbed structural section changes from one side of the concrete median barrier to the other side throughout the length of the project. Refer to Construction Detail C-9. When the lower roadbed structural section is on the northbound side (i.e. sheet X-4 station 549+50 to station 565+78.65), no structural section is required to be constructed on the southbound side. When the lower roadbed structural section is on the southbound side (i.e. sheet X-3 station 529+91.15 to station 540+79.57), at minimum, the 0.70-ft AS layer needs to be constructed so as to support the concrete median barrier. Although the drawings indicate that the full width of the 0.70-ft AS layer has been placed on the southbound side, refer to SC-6, stage 2 Work, paragraph 3: Perform earthwork as necessary, place base material as necessary and construct the concrete barrier in the median. Refer to SC-1 and SC-2. There is not enough room in stage 2 to construct the inside strip of concrete pavement from one end of the project to the other in the southbound direction until traffic is shifted. The inside strip of concrete pavement in the southbound direction, as well as the concrete median barrier, would need to be in place to contain and properly construct the HMA median shoulder in the southbound direction.

Inquiry #22: Follow Up to Bidder Inquiry #7 & CT's Initial Response:

" Inquiry #7: The cross section detail "A-A" shown on plan sheets U-2 & U-3 show the required backfill for an existing 8" PG&E gas line. What are the excavation requirements for an existing 8" PG&E gas line? Does PG&E require any permits or inspection fees for this work around the existing gas line?

Response BI #7B. The PG&E utilities are located within State's Right of Way. No additional PG&E permits will be required.
Response posted 10/28/2019 "

Contractor is in receipt of Addendum 4 which clarifies how the work on the 8" pg&e gas line gets paid.

However, the PG&E Excavation Requirements are missing. Specifically the contractors need the Special Provisions on what is required to work around an active 8" PG&E GAS Mainline. Here are a some quick questions that come to mind when working around a live 8" gas main. Will the line be shut off while we are excavating it? Can the contractors use standard excavation equipment to expose the line? What is the pressure of the existing 8" gas main line? Will a PG&E representative have to be present during the work (who pays for said representative)? Does this work have to be hand-dug? Can we expose the entire pipe run & then back-fill? Does the excavation & backfill have to be done in phases? Does the main have to be supported in place when exposed? Do our crews need any special PG&E training? What are the contingencies if 8” gas mainline gets damaged? Please provide the specific excavation requirements that address some of the questions above so that all the bidders can bid the work equally.
