ADDENDUM #1

to

BID NO. B24-09

North Landfill Cell 1 Construction

The following shall become as fully a part of the above-named drawings, specifications, and bid documents as if therein written and shall take full and complete precedence over anything therein contained to the contrary.

Acknowledgment: Each bidder MUST indicate on the Bid Form their acknowledgment of this addendum or their bid will be rejected.

Each bidder shall be responsible for reading each item of this addendum to ascertain to what extent and in what manner it affects the work to be performed.

1. Addendum No. 1 – I. 1st Set of Questions & Responses II. Revisions

I. 1st set of Questions & Responses:

Question #01: In the Bid schedule under the Geosynthetics scope there is a reference to a Leak Location Survey Section 04 45 47. I couldn’t find this section in the Bid Package.

Could you please share a copy of that section with us?

Response #01: The Bid Schedule reference for item 13A, Leak Location Survey, is incorrect and should have referenced Section 01 45 47. A revised bid schedule will be issued, at a later date, to correct the reference.

Question #02: RE: Perimeter Road Woven Geotextile. The spec appears to be written around the properties of the 180N nonwoven geotextile (specifically the grab tensile elongation of 50%) but the product states a woven drainage geotextile. I am not aware of any woven products that would be able to meet the elongation percentage required. Please advise.

Response #02: A grab tensile elongation of 50% would not be achievable for a woven geotextile. See amended required properties for the perimeter road woven geotextile application below in Section II. Revisions published with this Addendum.

Question #03: Can the CAD files be distributed to bidders as soon as possible, please (i.e. – separate addendum)?

Response #03: No. Per page 6 of the ITB, "CAD files will only be released to those who complete and return an electronic file acceptance waiver/disclaimer and limited license release form. Email the Contact Person identified on page 1 of the ITB to request CAD files."

Question #04: Has the “work by others” noted on sheet C300 been awarded already or is that in a separate ITB? Has that ITB already been issued/closed?

Response #04: "Work by others" noted on sheet C300 has already been awarded under a separate Invitation to Bid, #B24-06, North Landfill Infrastructure Construction.

Question #05: We see on the ITB that the Pre-Bid Meeting is a Virtual Meeting. Is it only a Virtual Meeting or are you having it on-site as well so we can walk through the site?

Response #05: There are no plans for an on-site walk during or after the Pre-Bid Meeting.

The meeting will be conducted entirely virtually, and no additional meetings are scheduled.

II. Revisions:

The following Project Manual Specifications have been revised and a summary of the revisions are provided below. An updated Project Manual document will not be issued as part of this Addendum, but will be issued to the awarded contractor with the For Construction Plans and Specifications.
