A DAMES & MOORE GROUP COMPANY <br /> <br />Thresher Square <br />700 Third Street South <br />Minnc::l.poli.q, Minnqob. 55415 <br />6123700700 Tel <br />6123701378 F:ax <br />www_brwint:.cQm <br /> <br />July 22, 1999 <br /> <br />Mr. Brian Fritsinger <br />City Administrator <br />City of Arden Hills <br />4364 West Round Lake Road <br />Arden Hills, MN 55112 <br /> <br />RE: 1999 Seal Coating Project <br /> <br />Dear Brian: <br /> <br />Bids were received and opened for the above-referenced project on July 21, 1999. One bid was received <br />from Allied Blacktop in the amount of $25,970.00. The bid included a 10% bond as required by the <br />Project Manual and was verified as correct. The Contractor did not include a bid price for slurry seal <br />coating the park trails indicating that a subcontractor is not available to perform the work as specified in <br />the contract. <br /> <br />Slurry seal coating in the metro area is predominantly accomplished by a contractor located in Madison <br />Wisconsin. Nick Landwer from BRW contacted them by phone and they indicated that they arc too busy <br />to do work in the Twin Cities this year on projects with small scopes such as that included in the trail <br />portion of the project. <br /> <br />The Engineer's Estimate for the work (excluding trail seal coating) is $28,000.00. Although only one bid <br />was received for the work., the City Engineer feels that the Contractor's bid represents a reasonable and fair <br />price. The City has had very positive experience with Allied Blacktop in the past and are confident that <br />the Contractor is able to complete the work satisfactorily_ <br /> <br />Based upon the current market situation, it is not possible to provide a slurry seal coat for the Lexinl,'1.on <br />Avenue trail as was intended in the project this year_ Slurry seal coating is a specialized process which <br />provides a very smooth finished surface and thcrefor was selected for the trail work included in the project. <br />It is potlSible to seal coat trails using the same equipment as specified for the street portion of the project <br />with the modification of aggregate size to provide a smooth surface as desired for trails. Allied Blacktop <br />has indicated that they would be willing to complete the trail seal coating using a modified mix if the City <br />desires. rhe estinlaled cost of scaling the trail using this method is $5,000.00 which is approximately 25% <br />less expensive than the slurry seal coating specified in the original project. Several municipalities do <br />perfonn seal coating of trails with this modified seal coat mix and have achieved acceptable results. <br /> <br />The project includes seal coating of Valentine Lake Road which was reconstructed in 1995 and received a <br />final bituminous wear course in 1996. The pavement markings on Valentine Lake Road are a preformed <br />type manufactured by 3M designed to last longer than standard painted or epoxy type markings. The <br />current road slTiping configU1'lltion includes a double solid yellow centerline and single solid white edgc <br />lines with miscellaneous directional arrowS and stop bars. Seal coating of this street would cover all of the <br />existing markings before the end of their useful1ife, In order to preserve the markings, they must be <br /> <br />0-. Worldwide <br />
