ADDENDUM #2
2019 CIPP Lining Project
Addendum #2 is being issued to respond to final questions received from bidders:
1. Will Davis-Bacon or prevailing wages be in effect for this project?
Answer: Davis-Bacon Act prevailing wage rates do not apply to this project.

2. There is a conflict between the retainage as stated in the Instructions to Bidders,
Article 20 and the Sample Agreement.

Answer: Instructions for Bidders, Article 20, Retainage shall be deleted in its
entirety and replaced as follows:

ARTICLE 20 =RETAINAGE

20.01 Provisions concerning retainage and Contractors’ rights to deposit
securities in lieu of retainage are set forth in the Agreement, Article 6.02
Progress Payments; Retainage.

3. Are we to assume that the Contractor must reinstate catch basins that might be tied
into the pipes to be lined?

Answer: All sewer service connections and catch basin laterals shall be reinstated
after lining.

4. Can you identify the diameter of the existing pipe on Nye Avenue?

Answer: The diameter of the sewer pipe on Nye Avenue is 8-inch.

5. Various questions have been asked regarding the number and location of point repairs?

Answer: Addendum #1 revised the quantity of point repairs and removed the
specific street locations of point repairs. Please be advised that point
repairs may be necessary at various locations as determined by the
Engineer after reviewing the pre-lining or post-lining videos. The
Contractor’s attention is directed to the Supplementary Conditions, Article
A, PROSECUTION OF WORK.

6. Are flow rates available for bypass flow expectations?

Answer: Specific sanitary and storm water flow rates for the sewers to be lined are
not available; however, a Sewer Infrastructure Map dated 9/27/2018 is
attached to this Addendum for reference. The map shows the Nashua
sewer system as well as general information about dry weather flows at
various CSOs in the City. Please be advised that all sewers to be lined are
combined sanitary/storm sewers subject to wet weather flow.

7. A question was asked regarding the detail of inside drops in sewer manholes?

Answer: Inside drop manholes shall be constructed as detailed on the Standard
Sewer Details — Sheet 35. Inside drops would be used as a pay item if an
existing inside drop was removed for lining of the sewer manhole.
Reconstruction of the drop would be completed as detailed, and the
diameter of the drop shall match the diameter of the incoming pipe.

8. A question was asked regarding the lump sum payment for Mobilization (Item 8)?

Answer: Delete Paragraph 2.03 B of Section 01150, MEASUREMENT AND
PAYMENT, PART 2 - DESCRIPTION OF PAY ITEMS, and substitute
the following:

2.11 PROJECT START-UP AND PROJECT CLOSE OUT:

A. MOBILIZATION
Measurement:
Mobilization shall be measured as a LUMP SUM as specified herein.
The total cost for this item shall not exceed 5 percent of the total of all
bid items excluding this item.

Payment:
The contract price for ITEM 8 shall constitute full compensation to the

Contractor for the general mobilization and demobilization necessary to
make the contract operational, exclusive of the cost of materials.
Payments toward the lump sum will be made at each payment
requisition based on the percent of contract amount completed. Final
payment of this item will be paid based on the percent of the contract
amount completed. Should the contract be terminated prior to
completion, or the contract work not completed, total payment for this
item shall be proportional to the percentage of the contract amount
completed. No additional payment will be made if the contract value is
increased.
