RESOLUTION TO APPROVE CHANGE ORDER NO. 1 FROM
CORNERSTONE EXCAVATING,INC. FOR THE 2016 SANITARY SEWER
INTERCEPTOR MAIN EXTENSION PROJECT IN THE CITY OF FAIRFAX,
LINN COUNTY,IOWA
WHEREAS, the City Council of Fairfax, Iowa has contracted with Cornerstone
Excavating, Inc. for the 2016 Sanitary Sewer Interceptor Main Extension Project within
the corporate limits; and
WHEREAS,Hall and Hall Engineers, Inc., has recommended approval of Change
Order#1 as described below:
ORIGINAL
CONTRACT AMOUNT: $ 902,615.30
ORIGINAL CONTRACT
COMPLETION DATE: 65 Working Days
ITEM #1: Remove Line Item 4, "Install Temporary Walkways (10'Wide Temporary
Trail)" In its entirety from the Project quantities
ITEM #2: Remove 193 SY of"Removal of Existing Sidewalk(Existing Trail and
Temporary Trail)" (Line item 11)from the Project Quantities
ITEM #3: Remove 37 LF of"Removal of Existing Storm Sewer and Culvert Pipe
(Includes F.E.S.)All Pipe is 24" Dia. or Smaller" (Line Item 13)from the
Project Quantities
ITEM #4: Remove Line Item 35, "Storm Sewer Main, RCP Class III (24" Dia.)" in its
entirety from the Project Quantities
ITEM #5: Add 10 LF of"Casing Pipe—Boring and Jacking" (Line Item 20)to the
Project Quantities AT A REDUCED UNIT PRICE
During Drilling and Boring Setup by the Contractor, it became evident that there was not sufficient
room to provide a safe temporary trail for use during boring operations under Highway 151. The
adjustments of quantities outlined in Items 1 and 2 reflect the negation of the installation of
temporary trail, and its subsequent removal from the project scope.
The Contractor requested that the existing 24" Diameter RCP Storm Sewer near Station 3+50 of
the proposed sanitary sewer alignment be allowed to remain in place during boring operations,
and that the sanitary sewer casing pipe be extended beyond the limits of this pipe an additional
10 LF of casing, for the same cost as the total of Items 3 and 4 above. The City's Engineering
Representatives determined that this is acceptable because the storm sewer pipe remaining in
place will allow any storm water to bypass the bore pit and trench during construction, and the
additional casing will reduce the risk of any pressure on form the storm sewer pipe onto the
proposed sanitary below. If project conditions dictate that the storm sewer pipe still needs to be
removed due to settling 1 damage, the Contractor will perform this work at no additional cost to
the City.
