Van Milligen MCVM/jh Attachment cc: Barry Lindahl, Corporation Counsel Cindy Steinhauser, Assistant City Manager Michael A. Koch, Public Works Director TO: FROM: SUBJECT: CITY OF DUBUQUE, IOWA MEMORANDUM October 8, 2001 Michael C. Van Milligen, City Manager Michael A. Koch, Public Works Director 2001 Harbor Maintenance Dredging Project INTRODUCTION The enclosed resolution provides for the award of the construction contract for the 2001 Harbor Maintenance Dredging Project. BACKGROUND The City of Dubuque has a contractual obligation under various riverfront-leased properties to maintain adequate harbor depths for navigation. The City is required to perform maintenance dredging operations at several river terminals and marina locations as required per lease agreements to facilitate adequate depth for commercial barge and recreational navigation. Per the current lease agreements, the City is required to dredge six (6) docking facilities: one located outside the Ice Harbor Gates--Dubuque Terminals (Newt Marine Service); three of which are located in Dove Harbor--Alliant/Interstate Power, Agri- Grain and Koch Materials; one located in the Peosta Channel--Peavey Company; and one located at the Dubuque Yacht Basin (Shanley Marina). The quantity of material required to dredge the six (6) docking facilities to a harbor depth, specified per the lease agreements, is approximately 37,100 cubic yards, this correlates to an estimated cost of approximately $520,000. However, because the cost to dredge the six (6) docking facilities exceeds the available budget, the quantity to be dredged has been scaled back to the budgeted funds. In 1998, the City performed maintenance dredging operations at four (4) of the above docking facilities, including: Dubuque Terminals (Newt Marine Service); Alliant/Interstate Power; Agri-Grain; and Koch Materials. The Dubuque Yacht Basin has waited the longest and has the greatest current need for dredging operations. It is, therefore, recommended that the City concentrate all the available funds to this one site. Below is a list of the leased riverfront properties which outlines the quantity of material required per lease agreements and the allowable quantity of dredge material per available funding.

Total Dredge Quantity 37,100 Cu.Yd. 6,400 Cu.Yd. DISCUSSION The proposed project scope of work includes the mechanical dredging of one (1) marina area located at the Dubuque Yacht Basin. A map is attached which shows the dredge project location and the temporary disposal site. The dredged material will be loaded onto a barge and then off loaded at a temporary disposal site north of the 16th Street Bridge at the Peosta Channel. Therefore, the material will be allowed to dewater; and under a future contract, the dried dredged material will be loaded into trucks and transported to an upland disposal site. During the bid process, it was brought to the attention of staff that the Corps of Engineers had saturated the marine market over the past 60 days with emergency repair work. With many potential bidders already under contractual obligations to complete the Corps work yet this marine season, staff was concerned that the dredge project specified completion date of December 14, 2001, may discourage interested bidders. After discussions with the Dubuque .Yacht Basin, it was determined that a completion date of May 1, 2002 would be agreeable to complete dredging operations prior to the start of the 2002 recreational boating season. In an attempt to encourage competitive bid proposals, prior to receiving bids, staff issued an addendum, which changed the dredge project completion date to May 1, 2002. BiD RESULTS Sealed bids were received for the 2001 Harbor Maintenance Dredging Project on October 4, 2001. The Iow bid was submitted by Newt Marine Service of Dubuque, Iowa, in the amount of $78,880. The following is a summary of the bid proposals received: Newt Marine Service JF Brennan Company RECOMMENDATION $78.880 $91,960 BUDGET iMPACT The cost estimate for the 2001 Harbor Maintenance Dredging Project is as follows: Dredging Contract Contingency (10%) Engineering & Inspection (5%) Total Dredging Estimate Temporary Disposal Site Prep Total Dredge Project Estimate Estimate Bid $ 94,100 $ 78,880 9,410 9,410 5,175 5,175 $108,685 $ 93,465 $ 20,000 $ 20,000 $128.685 $113,465 The project will be funded from the Local Option Sales Tax Fund under a Capital Improvement Program appropriation in the amount of $50,000 for FY 2002 and a carryover balance from FY 2001 in the amount of $80,000, for a total available budget of $130,000. I would recommend that the construction contract be awarded to Newt Marine Service in the amount of $78,880, which is 16% under the engineer's estimate, with a project completion date of May 1, 2002. After the construction contract is awarded and the pre-dredge marina survey soundings are completed, the quantity of material to be dredged will be adjusted to correspond with the available budget. The total estimated cost to dredge the six (6) docking facilities, as required per the lease agreements, is approximately $520,000. Additional funds will be programmed for the disposal and placement of the dredged material at the six (6) docking facilities in Fiscal Year 2003 and future CIP projects for dredging the balance of the material required for compliance with the leases. ACTION TO BE TAKEN The City Council is requested to adopt the attached resolution awarding the construction contract to Newt Marine Service. Prepared by Robert D.
