Inquiry #1: Reference 20-2.16 Optic Loop Theft Detectors (OLTD) and LD-22. There is no wiring diagram or indication as to where the OLTD monitoring points connect at each work location. Please advise if the extent of wiring for the OLTD is limited to just the "equipment pad" area or if wiring is required at other points (i.e. the furthest RCV in the system). If the later please identify distances for each work location and if the necessary spare conductors are avaiable.

Inquiry #2: Sheets E104, E-105, E-106, E-108, E-111 and E-113 all show wiring to be replaced. The plans have a [2] where there are gaps indicating a length between plan symbols. Note [2] refers to pull boxes and not any lengths. We are unable to determine the lengths of the wires to be replaced as there are no stationing marks or lengths given. Please provide the missing lengths.

Response #2: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 #7: The detail for the installation of the new valve boxes indicates a number 5 box with a minimum one foot concrete ring around each one. Where valves are in manifold, does there need to be two feet of concrete between each box or one foot?

Response #2:Each new valve box will be constructed with a minimum 12” concrete band around all sides of the No. 5 size valve box. Contractor should bid the item as described in the contract plans.
Response posted 09/30/2013




Inquiry #8: Currently where valves are in manifold they are one foot apart per standard detail and also the great majority are number 9 boxes. This means that the box cannot just be replaced since the new number 5 box is larger. Can the concrete between each box be less than one foot wide, or must the valve manifold be excavated, removed and re-plumbed? If the manifold needs to be extended in length some of the valve wires may not be long enough to reach to the new valve location.

Inquiry #10: In numerous locations existing controllers and the associated pull-boxes for 24V field wiring are incorporated in the new security enclosures. The conductors past the pull box will be direct burial, meaning as drawn, there will be wiring under the new concrete pads which is not in conduit. There is nothing on the plans or in the specifications regarding the existing conductors.

Inquiry #14: Sheet E-115 Detail "A", Note 4, says to anchor the frame with six 1/4" x 2-1/2" concrete anchors. My understanding is that the frames already come with welded studs embedded in the concrete. How are we to add six anchors?

Response #2:The traffic pull box must be manufactured with the frame anchored to the box with the specified anchors. See Special Provisions Sheet 261 of 278, (section 86-2.06C Traffic Pull Boxes).
Response posted 10/02/2013




Inquiry #15: Note 5 on Plan Sheet LD-22 calls for ¼” x 2 ¼” concrete anchors be installed in the new Traffic Rated number 5 valve boxes to anchor the box to the concrete collar. The wording is identical to the Cal Trans Standard Specification for the anchors for metal frames for Traffic Rated boxes. The frames and anchors for those frames are pre-cast into the Traffic Rated boxes when they are manufactured, but not any anchors for a concrete collar. Therefore they would need to be installed after manufacture. The details for the installation of the concrete collars and Traffic rated boxes do not show these anchors. A concern is that concrete anchors are set into existing concrete either by being hammered in place or by means of an expansive bolt. Both methods have a strong possibility of either spalling the interior face or cracking the box, or both. As written the new concrete anchors will be installed at the same positions as the frame anchors which could increase the chance of damaging the box.
Are the anchors for the concrete collars needed? They are not being used on the box replacements being done currently.

In the detail sheets page No. LQ-3 and LQ-4 under the heading Replace Valve Box (No. 5 (T))the total quantity is 80 ea. The quantity of valves being replaced in the quantity sheets totals is 1020 ea. Does No. 1 in section 20-2.11B(1) General, mean that the contractor is to provide a new valve box and cover for every valve that is to be replaced (1020 valves ea.)?

Response #2:Yes, the cost of each replace Remote Control Valve (1020 total) should include the cost of a new box and cover as well. This is a standard irrigation valve box as shown in the standard plans. The cost of this box and cover are included with the cost of the valve per the standard specifications. With regard to Replace Valve Box (No. 5(T)) (80 total) this work includes replacing the old valve box at existing master remote control valves with a new traffic box. At these locations, the existing master remote control valve will remain in place.

Inquiry #25: Addendum 3 at the top of the 4th page states that sections 20.02A(3) and 20.02A(4) are not to be used, indicating that there is to be no check and test of existing irrigation, and no repair of deficiencies noted as a result of a check and test. However, a Bid Item 38 Operate Existing Irrigation Facilities has been added to the Bid Schedule. It is not possible for a contractor bidding now to know whether the existing irrigation will be functional, and if not, what the extent of the necessary repairs might be. In addition, water meters , underground supply lines , control and neutral conductors and electrical conduits are specifically excluded from the bid item. Any of these excluded items could prevent the functioning of the systems if they are deficient.
We urgently request that the deleted sections be reinstated and the language of 20-2.02 revert to standard, with the inclusion of the costs of performing a check and test as part of Bid Item 38.

Response posted 10/14/2013


Response #2:The purpose of the standard “check and test existing irrigation” specification is to identify deficiencies in the existing irrigation system and then pay for correction of those deficiencies as change order work. This project is different. An initial check and test will not be required for any location because repair of existing deficiencies is contract work. The repairs to the existing irrigation system are listed in the contract documents.

As directed in paragraph 3 of Section 20-2.02C(3) “Operate Existing Irrigation Facilities” of the contract RSS, operation of the irrigation systems during repairs may be done manually.
