Inquiry #1: Bid Item 22 - Control and Neutral Conductors (Armor-Clad): I cannot find any notes or details or symbols on the plans indicating locations where these conductors are required to be installed, or the number of conductors to be installed. Are any additional pull-boxes required for armor-clad installation, or will any pull-boxes for these conductors be included in the bid item for crossover pull boxes?
Inquiry submitted 09/24/2013

Response #1:For locations and number of Control and Neutral Conductors (Armor-Clad) to be installed, please see sheet LQ-3 of the contract plans. The column for 3” Plastic Pipe (Schedule 40) (Supply Line) shows lineal feet of irrigation main line to be installed and the remarks column provides the distance of the relocation of irrigation facilities.

No additional pull boxes are required for armor clad installation. Armor clad installation will be done at existing pull box locations. All existing pull boxes at crossovers and irrigation controllers will be replaced with No. 5(T) pull box as shown on sheet LQ-4 of the contract plans. This work will be paid for as Replace Pull Box (No. 5 (T)).

Inquiry #2: All pull boxes and valve boxes for the irrigation systems that are indicated to be replaced, are indicated as being replaced with No 5 Traffic Rated concrete boxes with metal bolt down lids. On page 31 of the Special Provisions an addition to section 86-2.06 is indicated for Tamper Resistant Cover for Non-Traffic Rated Pull Box. This would seem to indicate that the existing Irrigation Crossover Boxes and Valve Boxes are being replaced with new boxes that do not have Tamper-Resistant lids. It is my understanding that the retrofit is because of vandalism so shouldn’t the new boxes for the irrigation have Tamper-Resistant lids also?
Inquiry submitted 09/24/2013

Response #1:Attention is directed to sheet LD-22 of the contract plans regarding locking mechanism for traffic rated pull boxes. Note 6 on sheet LD-22 refers the contractor to the detail in the electrical sheets and the requirement to furnish and install 3/8"-16 coarse thread penta head hold-down bolts at each traffic rated pull box.

Inquiry #3: Bid item 13 gives a total of 1,020 RCVs to be removed but Bid Items 23 through 26 give a total of 1,030 RCVs to be installed. Are 10 RCVs being added? If so where? Will new Armor-clad conductors need to be run for them?
Inquiry submitted 09/24/2013

Response #1:Quantities shown in bid item list are identified on the list as “Estimated Quantities”. Please see LQ sheets in contract plans for actual quantities.

Inquiry #4: The Irrigation Sprinkler Schedules on Plan Sheets 6 through 39 (ISS-3 through ISS-36) list a total of 2,003 RCVs with size and location, 13 more with size and a notation of “M”, 28 with no size and with a notation of “M” and one listed as “Removed” with no size or location. These quantities do not correspond in any way with the bid quantities given for Bid Items 13 and 23 through 26. Please indicate which of the listed valves are being removed, and which are being replaced.
Inquiry submitted 09/24/2013

Response #1:Please see Notes #2 and #3 on sheet ISS-1 of the contract plans. Please note the title of the tables shown on sheets ISS-3 through ISS-34 of the project plans - “Existing Irrigation Controllers”.

Inquiry #5: Sheet E-27 has two heavily shaded pull box symbols shown on the NB Route 180 On-Ramp that are connected to single 6' x 6' loops. Are these pull boxes and count loops new to be installed? Similar question where this also occurs at other locations?

Inquiry #6: Sheet E-57, On SB Friant Rd On-Ramp, existing conduit leaves pull box with note to add 1 5CSC and 1 DLC, but no destination seems apparent, as the line does not connect to anything. Where should this be routed and what should it be connected to?
Inquiry submitted 09/30/2013

Response #1:Submitted for consideration.
Response posted 09/30/2013


Response #2:Referencing Sheet E-57, the destination of the 1-5 conductor signal cable (CSC) and 1 loop detector lead-in cable (DLC) is the adjacent pull box where the 1-5CSC conductors should be spliced to the ramp metering(RM) sign conductors and the 1 DLC should be connected to the Q-loop at the same pull box.

Inquiry #7: Sheet E-57, existing conduit crosses Friant Rd to pull box adjacent to two service pedestals, noted as adding 2#4 (RM). Should this connect to one of the service pedestals?
Inquiry submitted 09/30/2013

Response #1:Submitted for consideration.
Response posted 09/30/2013


Response #2:Referencing Sheet E-57, the 2#4 ramp metering(RM) conductors shall be terminated inside the service pedestal adjacent to the existing pull box.

Inquiry #8: Will the state please consider allowing to a C-27 licensed contractor bid on this project? The majority of the work is irrigation and it may be in the best interest of the state (for the sake of competition) to allow C-27 licensed contractors bid this project as a prime contractor.

Response #2:No, the license requirements won’t change.

Inquiry #9: The response to Inquiry #5 does not address the question. Are the count loops new? These seem odd, as they are the only such on the project.
Inquiry submitted 10/15/2013

Response #1:Submitted for consideration.

Response #2:The symbols show proposed/existing pull boxes and existing loops for Sheet E-27.

Inquiry #10: There seems to be some confusion about the remote control valves (RCV). 950 brass RCV's get removed in bid item 14. These get replaced with RCV's in Items 27-30. The "replace valve" detail on LD-22 (sheet 59) shows an exist valve box.
Questions
1. Does the valve box get removed and replaced with a new box?
2. If so, does the RCV get replaced with standard size concrete valve box and lid?
3. I am assuming these RCV's do not get a concrete collar around the valve box because none is shown.

Inquiry submitted 10/17/2013

Response #1:Yes, the valve box for each new plastic remote control valve gets replaced with a new valve box per the standard specifications. This is a standard concrete irrigation valve box as defined in the standard specifications.
Yes, valve boxes that house plastic remote control valves do not receive concrete collars. The only boxes to receive a concrete collar are those boxes that house remote control valve (master) (RCVM) as shown on sheet LD-22 of the contract plans.
