of Proposals, Bid Proposals, Contract Documents, and Specifications of the subject

project are hereby modified only insofar as the following clarifications, corrections,

changes, and amendments are concerned. The Bidder MUST acknowledge the

receipt of this addendum and attach a signed copy to the Proposal section of the

Contract Documents.

QUESTIONS

1- Sheet 9 / 10: Is the RIM of 315.01 for Manhole 14K15 at STA 42+36 correct? The

elevation profile does not match.

RESPONSE: Rim elevation for Manhole 14K15 is 315.01.

2- Can the laterals be replaced by pipe bursting?

RESPONSE: Yes, laterals can be pipe burst with fused HDPE

3- Where are the 2 EA manholes to be rehabilitated per Bid Item 17, 18 & 19 located?

RESPONSE: These are allowances for the City to field direct rehabilitation if

needed.

4- Spec 33 05 07 refers to conductor casings and annular space grouting, and that

the lengths of the conductor casings are shown on the drawings, which they are not.

Are conductor casings and annular space grouting required for the HDD installation?

RESPONSE: No, the soil condition within the project area doesn’t dictate the

use of a conductor.

specifications.

RESPONSE: A copy of the Geotechnical report is posted in the link below:
