The Geotechnical <br />Engineering Report indicates most of the AC thickness to be 4” thick, with no apparent <br />rock/ base underlayment. HWA-2 indicates AC thickness at 6”. For bidding purposes, <br />please define the section (AC/ Base) to be removed/ disposed of and how much of the <br />area is 6” thick versus the 4” thick balance. <br /> <br />Based on available information, the thickness of AC across the site ranges from <br />3” to 6” but is predominantly an average thickness between 4” and 5”. <br /> <br />Q61 - Drawing G-00-0021 provides a Legend for areas defined on this drawing. The <br />“Site”, Area 10 does not appear to be defined. Please provide an outline of this Area 10 <br />as it relates to Bid Item #6 1.a. <br />As noted in the legend provide on Drawing G-00-0021, the Area 10 site is defined <br />by the white area shown within the project property boundary and purple for the <br />instance of Lift Station 6.

After <br />gutting the station, the void is to be backfilled with structural fill. Can the top two feet <br />and deck concrete be a part of the structural fill? <br />As required by Specification Section 02 41 19, 1.03, “Demolish” shall mean <br />“Detach items from existing construction and dispose of them off-site unless <br />indicated to be salvaged or reinstalled.” Top two feet and deck of LS6 may not be <br />used as a part of the structural fill. <br />Q63 - Drawing CX-10-2005, Keynote 1 says to demolish Storm Manhole. What is the <br />diameter of this manhole? <br />Unknown, there are no records on the diameter of the existing storm manhole. <br />Q64 - Drawing CX-10-2003, Keynote 1 calls for the demolition of a Grated Vault. <br />Volume 7, Attachment A, Drawing B-9017 says to refer to Drawing B-9757 for possible <br />information on this Grated Vault. Drawing B-9757 is not a part of this attachment. <br />Please provide Drawing B-9757, and any other details, that provide information on this <br />Grated Vault to be demolished. What is the makeup of this sludge that needs to be <br />sucked out? This is needed to determine proper disposal. <br />All available as-built documentation is provided in Volume 7 Attachment A. Any <br />missing drawings are unavailable. Makeup of sludge that needs to be removed is <br />hardened material exceeding 20% solids that likely will require some jetting prior <br />to suctioning. See Specification Section 02 61 00 for handling requirements.
