Contract 05-1P7404 (05A2539)

The responses to bidder's inquiries, unless incorporated into a formal addendum 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)  Located at Culvert Location 2 (48" CMP), there appears to be a sinkhole spanning roughly 5' into the shoulder of the roadway on the inlet side of the culvert pipe.  Please confirm this repair is not included under the scope of this project?

A1)  Attention is directed to the contract's Notice to Bidders where the General work description is to Line Two Culvers.  Attention is also directed to Section 5-1.20A for information about other planned work in this area.  Place your bid in accordance with current contract documents.

Q2)  Located at Culvert Location 2 (48" CMP), there appears to be an inconsistency with the pipe sizing.  It appears as there is a 42" CMP Wedged in roughly 7-10 feet into the 48" pipe.  The Provided plans do not note any inconsistent sizing and or correction to said culvert pipe.  Please confirm whether scope includes the repair and replacement of said inconsistency or to install liner with current conditions.

A2)  Plan sheet D-2 accurately represents the existing pipe to be lined.  Attention is also directed to Standard Specification 1.01, "After contract approval, direct questions to the Engineer."  Place your bid in accordance with current contract documents.

Q4)  At Culvert location 1 (42" CMP) the downstream end appears to be filled about half way with sediment.  The surrounding area appears to be the same grade as the culvert pipe blockage.  Does CDOT anticipate the contractor to include the removal of these debris located within the immediate area of the outlet?  Please confirm the scope if any and whether additional permits to work within the stream bed are required.

A4)  Attention is directed to Section 71-3.01A(3)(b) Cleaning Pipe, of the contract Special Provisions.  Attention is also directed to Standard Specification 5-1.01, "Furnish the resources ... required to complete the work as described in the contract."  Place your bid in accordance with contract documents.
