Contract 05-0G4004

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 products specified are NSF certified products. Therefore, they are only available in certain manufacturer standard colors. Will a tintable, Non-NSF manufacturer's equal be allowed in order to provide the specified finish color or can the finish color be changed to an available color in the specified NSF products?

A1) Bid the coating according to plans and specifications and provide sample color to the Engineer for color approval.10Aug10.


Q2) Regarding Plastic Pipe (SUPPLY LINE): The SP pg. 125 calls for PVC 1120 or 1220 Pressure Rated. The Cost Break Down on SP pg. 122 calls for PVC PR 315. Which is correct?

A2) Both are referring to the same PVC pipe designation. The 1120 and 1220 refers to pipe Grade designated by ASTM. 23Aug10.


Q3) Regarding Plastic Pipe (IRRIGATION LINE): Neither the specifications or the plans have a specification for the Plastic Pipe (IRRIGATION LINE). This line has Type D-3 Emitters and the Emitter/Irrigation Line detail on sheet 41 appears as if design is looking for a PVC Flex Tubing as the IRRIGATION LINE, this would make sense because there are flush valves at each end of the line. What is the specification for the Plastic Pipe (IRRIGATION LINE)? Please Clarify.

A3) Plastic pipe (irrigation line) is defined in the standard specifications, section 20-1.15B(2) 23Aug10.


Q4) Regarding Irrigation FLUSH VALVE: What is the specification for the FLUSH VALVES shown on plan sheet 38, and shown in the Cost Break Down on SP pg. 122? Do the Flush Valves need a Valve Box? If so what size? Please Clarify.

A4) The flush valve detail in the 2006 standard plans (H7, page 207) is for buried plastic pipe (supply line). For plastic pipe (irrigation line) Flush valves can be any devices that can be opened and closed to flush debris from the system. Since the plastic pipe (irrigation line) is placed on-grade, the flush valves can be on-grade too. No valve box is required. 23Aug10.


Q5) According to the specifications, item 39 "Highway Planting" includes item 41 "Plant (Group M)". "Highway Planting" also includes mulch, fertilizer and soil amendment. Therefore, the cost for "Plant (Group M)" would included in two different line items. How should the installation cost of these items be allocated?

A6) Please refer to Addendum No. 2 dated Sept. 21, 2010. 23Sep10.
