Van Mil)igen MCVM/jh Attachment cc: Barry Lindahl, Corporation Counsel Cindy Steinhauser, Assistant City Manager Michael A. Koch, Public Works Director CITY OF DUBUQUE, IOWA MEMORANDUM February 15, 2002 TO: FROM: SUBJECT: Michael C. Van Milligen, City Manager Michael A. Koch, Public Works Director White Street Reconstruction - 21sT to 32nd Street INTRODUCTION The enclosed resolution provides for the award of the construction contract for the White Street Reconstruction - 21 sT to 32nd Street. DISCUSSION Sealed bids were received on February 7, 2002. The Iow bid was submitted b~y W.C. Stewart Construction Co. in Dubuque, Iowa, in the amount of $2,541,474.40. This amount is based upon the City bid alternate for plastic pipe for the sanitary sewer main and 4" private sewer laterals to the White Street right-of-way. The bid is 14.1% under the engineer's base estimate. During the City's review of the bids, it was noted that two contractors significantly underbid one of the bid items that. was tabulated incorrectly, causing what is called an "unbalanced bid". An unbalanced bid is a bid containing unit prices which do not reflect reasonable and actual costs plus a reasonable proportionate share of the bidder's anticipated profit, overhead costs, and other indirect costs to complete that item. The bid item in question was 48-inch storm sewer manhole sidewall. The cost to supply 48-inch sidewall is over $60 per foot. One contractor bid a price to purchase and install the manhole sidewall for $1 per foot and the second contractor for $30 per foot. These pnces obviously do not reflect reasonable prices for this work and is a clear case of unbalanced bidding. Unbalanced bidding is prohibited by the City's standard specifications because it makes comparison of bid proposals extremely difficult and can result in a situation where the final contract price for the "lowest bidder" can actually be higher than if the contract were awarded to one of the other bidders who fairly priced the bid item. The base bid included the reconstruction of 6,287 feet of sanitary sewer main with ductile iron pipe. The City also bid an alternative of PVC pipe for the sanitary sewer main. A significant benefit was realized by bidding the PVC sewer main pipe versus the ductile iron pipe. The cost-savings on the PVC sewer main was n excess of $95,000 over the ductile iron bicl; this is an $185,000 savings from the engineer's estimate. The base bid included 298 sewer laterals to be replaced with cast iron pipe. An alternate bid item was included to reconstruct the pdvate sewer laterals with PVC piping. The PVC-constructed sewer lateral is being recommended for it was n excess of $43,000 under the cast iron bid for pdvate laterals. Each property owner's sewer lateral assessment will be reduced by more than 30% over the odginal engineer's estimate. A summary of the bid is as follows: WC Stewart Construction Co. Tab Construction Tschiggfrie Excavating Fischer Excavating, Inc. $2,541,474.40 2,609,220.50 2,852,800.22 3,640,986.85 The two unbalanced bids were rejected as not being responsive to the bid specifications, and therefore, are not considered valid bids. This does not have an effect on the determination of the Iow bidder. RECOMMENDATION I recommend that the construction contract be awarded to WC Stewart Construction Co., in the amount of $2,541,474.40, which is based on the alternative of PVC piping. BUDGET IMPACT A summary of the project cost is as follows: Construction Contract Contingency Engineering Estimate Bid $2,957,175.90 295,717.59 487,934.02 $2,541,474.40 295,717.59 487,934.02 Total Project Cost $3,740,827.51 $3,325,126.01 The project will be funded as outlined: Estimate Bid Street Construction Fund Local Option Sales Tax Special Assessment to Private Properties Special Assessment Deficiency to be Paid by City Special Assessment for Water Services Special Assessment for Sewer Laterals Special Assessment for Sidewalks Sanitary Sewer Construction Fund Watermain Construction Fund $ 794,677.67 $ 517,446.81 1,102,002.54 1,080,343.86 66,919.83 358,859.35 414.35 2,142.41 89,587.30 88,387.30 401,965.42 277,070.50 10,339.40 7,398.82 .693,505.30 481,602.98 281,415.70 511,873.98 Total Project Funding $3,740,827.51 $3,325,126.01 Street Construction Funds are available from the Fiscal Year 2001 budget in the amount of $1,010,922 and $1,102,283 from the Fiscal Year 2002 budget, for total City funds available of $2,113,205. This leaves a balance of $513,272 in Street Construction Funds. A balance in the Sewer Construction fund ($416,879) is available due to savings on the High Bluff Sanitary Sewer Project and delay of the Keyway Sanitary Sewer Project. In addition, $64,724 of the Street Construction Fund balance of $513,272 noted above will be used to fund construction of the sanitary sewer. The Water Extension Capital Improvement Project will be used to cover $253,000 of the cost of watermain, with the balance of $258,874 coming from the Street Construction fund balance noted above. Low- to moderate-income property owners subject to street and sewer lateral assessments will be eligible for financial assistance ranging from 20 to 100 percent of the Street assessment for owner-occupied resident property depending on family size and income level. This financial assistance program is made available through the 1% Local Option Sales Tax.

Thank you for your consideration. POSSIBLE REM D S FOR Tm* 21ST TO 24TH ST PROBLEMS BEFORE THE 21ST TO 32ND ST RECONSTRUCTION STARTS. A) Construction of stop lights at 22nd and White Street intersection. Slows north-south (speed-way) traffic, frees grid lock traffic to go north south. or . B) Kound out the east side of traffic island at 21 st and White, so vehicles must slow to ~ get-irotmd going north, also to keep.unwanted oversized tracks from coming north. On ilew island please po~t siga ~ading [NO TRUCKS OVER 2 AXLES ALLOWED]. 01' C) We propose narrowing Wtfite St. in the 21st, 22nd, and 23rd hundred blocks bom 41' to 37' or 38' (on the east of 22nd and 23rd) and on the (west of 21st) and white. 1) Would allow a wider green area to accomodate small trees on the 22nd and 23rd lmndred blocks on tl~: east side, and some green area on the west side of the 21st block. AH major overhead wires on wcst side. 2) This would better align the 21st hundred block of White with the 22nd hundred block at 22nd street h~tersection. 3) Lengthen driveway approaches between sidewalk and curb making a lower pitch to driveway so vehicles 'won't hit bottom driving up. There are no alleys between Central-White-Jackson. 4) Would save the city between $15,000-$20,000 by narrow~g these (3) blocks from 41' to 37' and maybe more if thickness is 7" instead orS" as propose& (-4' X 3 blocks=S15,000-$20,000 saved) or Another possqble remedy to stop excessive (speed-way by-pass) and oversized traffic coming north on 22nd mid 23rd and White would be (2) simple signs at 24th and White say'atg {ONE-WAY SOUTH ONLY} and the (2) at 22nd and White saying {DO NOT ENTER}. or CE) I'm open to ideas.* It's been 75+ years!! PLEASE! PLEASE.* PLEASE! Let's do it VI NO,
