ADDENDUM #1
2019 CIPP Lining Project
Addendum #1 is being issued to respond to questions or suggestions received from bidders:
1. In the design criteria for CIPP for the Nashua job the soil modulus design criteria calls
for 500 psi. Typically the soil modulus is 1000 psi. In using 500 psi for design, the
resulting liner thicknesses will be greater than they may need to be, and will cost the
City more money. Would a consideration be made to increase the soil modulus design
criteria to 1000 psi?
Answer: The design criterion for modulus of soil of 500 psi as specified in Sections
02650 and Section 02651 shall be revised to 1000 psi.
2. Would it be possible to have materials approved in advance of bidding for the manhole
rehabilitation work?
Answer: Product approvals will be handled after the bid has been awarded, and be
reviewed for compliance with the specifications by the Engineer as part of
the contract submittal process.
3. What is the Engineer’s estimate for Nashua?
Answer: The City will not provide bidders with the Engineer’s cost estimate for the
Project.
4. A suggestion was made for the City to reevaluate the basis for the quantities for the
point repair items. The concern is the degree of uncertainty with respect to the total
repairs which will actually be performed.
Answer: The Bid Schedule has been revised to reduce the quantity of point repairs
to reflect the known locations of likely point repairs, and Item #12 has
been added to the Bid Schedule entitled “Allowance for Additional Point
Repairs”. Add the following to Section 01150, MEASUREMENT AND
PAYMENT , PART 2 —- DESCRIPTION OF PAY ITEMS:
2019 CIPP Lining Project Addendum #1
Nashua, NH Page 1
215 ALLOWANCE FOR ADDITIONAL POINT REPAIRS
A. ALLOWANCE FOR ADDITIONAL POINT REPAIRS
Measurement & Payment
Item 12 is an ALLOWANCE value which has been established
in the Bid Schedule as a means to include funds in the event
that the Contractor is directed to perform additional point
repairs in excess of the quantities listed in the Bid Schedule.
Measurement and payment for additional point repairs shall
be based on the unit prices for the appropriate point repair
and roadway restoration items in the Bid Schedule.
5. A concern was raised regarding the maximum rate of $30 per hour for flaggers.
Answer:
The City has decided to bid the cost for flaggers on an hourly basis
without specifying the maximum hourly rate. The Bid Schedule has been
revised to show the quantity of flagger hours under Item 9B. Delete
Paragraph 2.12 B of Section 01150, MEASUREMENT AND PAYMENT,
PART 2 - DESCRIPTION OF PAY ITEMS, and substitute the following:
2.12 MAINTENANCE AND PROTECTION OF TRAFFIC
B. FLAGGERS
Measurement:
The quantity of Flaggers will be measured by the HOUR
based on the actual number of hours authorized, as
determined by the Engineer. The Contractor shall supply
qualified flaggers as stated in Section 618 of the NHDOT
Standard Specifications for Road and Bridge Construction,
(Approved and Adopted in 2016). Daily coverage needs to be
approved by the Engineer. The Contractor's schedule for
flaggers shall be agreed upon cooperatively with the Engineer.
Payment:
The approved quantity of flagger hours shall be paid at the
contract price for ITEM 9B. Payment shall constitute full
compensation to the Contractor for providing qualified
flaggers as required to direct traffic through or around the
Work as ordered by the Engineer, including all labor, high
visibility safety gear, tools and any other equipment necessary
to complete the work as specified herein. Payments to
Contractor will be made based on approved hours and
resulting dollar amounts.
