RESOLUTION APPROVING CHANGE ORDER TO ENGINEERING SERVICES
AGREEMENT FOR SANITARY SEWER SYSTEM EVALUATION
FOR THE CITY OF AMES, IOWA
WHEREAS, the ability of the sanitary sewer system to convey wastewater well into the future
is dependent on the removal of the current large amount of infiltration and inflow (I/I) in the system
that occurs during rain events; and,
WHEREAS,in order to minimize the need for costly expansions to the Water Pollution Control
(WPC) facility, as well as to convey flows from new development as the City grows, the City must
work to reduce the overall I/I in the system; and,
WHEREAS,to help accomplish this goal, a 2008 Sanitary Sewer System Study recommended
development of a full Sanitary Sewer System Evaluation (SSSE); and,
WHEREAS, on March 27, 2012, the City Council approved a contract in the amount of
$2,198,500 with Veenstra & Kimm (V&K) engineering consultants to complete the SSSE; and,
WHEREAS, as the data collection phase now nears completion, it has become evident that
investigation of the siphons (which enable flow of water beneath rivers and creeks) should also have
been included in the original contract;therefore, a change order to the contract is now being requested
to accomplish this work; and,
WHEREAS,the proposed change order also includes additional funding for heavy cleaning of
sanitary sewers and additional flow meters/flow monitoring; and,
WHEREAS, additional needs beyond those identified in the original contract have been
identified for areas that cannot be cleaned by City crews due to the nature of the needed equipment;
and,
WHEREAS, the overall change order is for an amount not to exceed $263,250; this will
increase the overall contract amount to $2,461,750.
NOW,THEREFORE,BE IT RESOLVED,by the City Council of the City of Ames,Iowa,that
the Change Order to the Engineering Services Agreement with Veenstra & Kimm for the Sanitary
Sewer System Evaluation in an amount not to exceed $263,250 is hereby approved.
