CUCCURESE, P.S.M. <br />CLINTON J. RAHJES, P.E. <br />STEVE D. SNOBERGER, P.E. <br />It is Carter Associates, Inc.' s (CAI) pleasure to present for your acceptance, the following revised <br />Proposal for professional engineering and surveying services associated -With the above mentioned <br />project. The Wabasso Bridge Reuse Main crossings consist of double 12 -inch diameter ductile iron <br />mains hanging under the bridge decks. There are 4 bridge crossings consisting of 3 low elevation <br />structures and a high causeway structure. Together, the total length of exposed pipe is <br />approximately 3,400 linear feet. Since installation, the metal pipes have experienced several small <br />failures, but have had no complete inspection for the weathering process caused: by the salty <br />environment. A quick visual view of the hanging pipes indicates the need for such an examination <br />based on the pictures we observed with you. <br />With the pipes being hung under each of the bridge decks, access is limited .to;a. mobile platform <br />deck. Rather than using a multi -boom lift crane, which would require drive lane closure for a. <br />significant time, CAI has experience, on this very bridge, using a Tolling scaffold for pipeline <br />inspection. During 2001-2003, CAI conducted: inspection; design; bidding; and inspection and <br />subsequent re -coating services for the 16 -inch diameter cast iron pipe currently hanging under the <br />south side of the Wabasso Bridge decks. Unfortunately, the inspection scaffold for that project no <br />longer exists. CAI would propose the same successful inspection techniques used on the south side <br />to inspect the County's Reuse Mains located under the north side bridge decks. Please find attached <br />our Engineering and Surveying scope of services and budget outlining the steps required to prepare <br />for the inspection, conduct the: field inspection; data review; engineering analysis; and eporting. <br />Our total price for the services as outlined and estimated Reimbursable Expenses shall not exceed <br />$56,048.42. These services would be furnished under our existing Engineering Contract with the <br />County, dated November 4th, 2014. Invoices would be billed only -for actual hours and costs as <br />identified hereafter. <br />Page 1 of )4 <br />N:\SDS\15-54 E(IRCUD Wabasso Causeway)\Proposal\Rev Proposal.doc <br />
