ADDENDUM NO. 1
(Page 1 of 2)
Make the following additions and modifications to the Contract Documents as follows:
(1) Attached is Revised Plan Sheet 1 of 3 which eliminates the full width intersection
water main replacement on three side streets intersecting Centerway. Those
side streets include Cornelia, Caroline and Eisenhower. This reduction requires
testing of the new water main on Centerway prior to making any connections of
side street pipes. The Revised Bid Proposal reflects a reduction in new pipe,
valve and street restoration quantities.
(2) Attached is Revised Plan Sheet 3 of 3. This revised plan eliminates the full width
water main reconnection at the intersection of Wilson Street and Park Avenue, as
shown on the plan. This will require testing and approval of the water main on
Wilson Street prior to the Park Street connection. The Revised Bid Proposal
reflects a reduction in new pipe, valve and street restoration quantities.
(3) Added to the Contract is replacement of water main at the intersection of
Milwaukee Street and Martin Road. The Addendum includes an 8-1/2 x 11 plan
sheet showing the replacement work at that intersection. The Revised Bid
Proposal includes quantities for new pipe, valves and street restoration at this
location.
(4) Attached is a Revised Bid Proposal and Revised Contract Quantities
Spreadsheet that shall be used by the Contractor to present their Proposal. The
revised Proposal reflects adjustment in quantities affected by the plan changes
and additions, as noted in Items 1 through 3 above. Quantities impacted by
these changes include but may not be limited to water main pipe, valves, street
restoration, sawcutting, and curb and gutter replacement.

(5) There are two items the Contractor shall make note of because of the changes in
Items 1 through 3 above:
The first is all connections to side streets cannot be made until the main line pipe,
either on Centerway on Wilson Street, has been completed and tested; whereas
the original design with new valve installation allowed for all interconnects prior to
testing of the main.
The Contractor shall re-evaluate the cost for traffic control because of the
changes in Items 1 through 3 above. The elimination of full width side street
connections on Wilson and Centerway should reduce traffic control costs. The
addition of the Milwaukee Street/Martin Road intersection will add work to the
traffic control item.
