RECOMMENDED ACTION We are see king Council approval of a Resolution allowing a negotiated contract with Bituminous Asphalt Sealing Specialists, Inc., a.k.a., BASS, Inc ., In an am~unl no! lo exceed $350,000 for our 1999 Micro- surfacing Program . BACKGROUND, ANALYSIS, AND ALTERNAT1\/ES li)ENTIFIED Micro-surfacing is a cost effective maintenance J•.,,mative !hat provides rut filling, leveling of existing pavements, a surface seal and a new wearir,g surrace . The finished product Is jet black, aastheUcally pleasing , and exhibits more traction than the original asphailic concrete (improved safety). Staff introduced "Englewood" micro-;urfacing in i SS i . Our objective was to develop a maintenance altemati,d to address the maintenance needs of roadway.; subjected to excessive traffic volumes resulting in pavement rutting and lanes requiring leveling treatment~ along with new wearing courses and surface ,eals. BASS has satisfactorily participated In a partnership arrangement with the City •.ir the last twelve years to construct our slurry and micro-surfacing programs , having now plar.ed a '"'al of 2,204,000 square yards of our design products (approximately 890 blocks, or 111 miles of roadway). Micro-surfacing requires highly specialized construction aquipment. Based on our last eight years of experience , we know that the use of continuous micro-surfacing equipment produces a superior product when compared to that applied with truck-mounted type machines. Continuous equipment provides cons istency of application and minimizes seams by reducing uqulpment stops and starts . Truck-mounted equipment was used in the construction of our earlier slurry products . Continuous micro-surfacing equipment can apply standard slurry produ~:s while standard slurry machines are not capable of applying micro-surfacing . The number of continuous micro-surfacing machines continues lo grow throughout the country ; BASS owns and operates two of these machines. BASS has successfully constructed mlcro- surtacing on selected arterials , collecto rs , industrial and local service streets In our ; ·191 , 1992, 1993, 1994, 1995, 1996 , 1997 and 1998 Micro-surfacing Programs . Staff continues to monitor slurry seal and micro-surfacing activities in the metro area . The workmanship of BASS, Inc ., particularly with micro-surfar.ing , appears to remain superior. lnco,slstency still exists In the mix designs used by others in the mr:,o area, although many more jurisdlct lor,s are again requiring the gray granite aggregate lha1 we have specified since 1987. Other user agencies continue to modify their s~•ciflcallons , suggesting that they are not completely satisfied with earlier products . It appears that many other cities continue to settle for standard slurry products Instead of micro-surfacing . This can be partially attributed to local contractors recommending and selijcting lower priced, lesser quality • components under competitive bid conditions . Also , slurry products tend 1, be more user-friendly during construction than micro-surfacing . It should be noted that micro-surfacing nas construction advantages over slurries in that micro can be used for rut filling and leveling In addition to providing the surface seal and new wearing surface that is obtained wtth standard slurry applications . Throughout our twelve year experience with "Englewood" slurry , micro-surfacing , and BASS , Inc ., citizen re.sponse continues to be positive. Experience with applying our product is crucial to a successful project. We continue to monitor and evaluate slurry and micro-surfacing contractors in the Denver area , and we may choose to recommend others for future years' work, depending upon their performance on other projects. However, our local choices continue to remain extremely limited . lntermountaln Re~11rfaclng , inc. (IMR) remains In the slurry market , and they attempted to enter the micro- surfacing market With a project in Littleton In 1997. Unable to develop a micro-surfacing product for Littleton, standard slurry was utilized wtth marginal results . Englewood had a contract dispute with this company In 1986-1987. Using older truck-mounted equipment, their micro-surfacing exp~rience with the Colorado Department of Transportation (COOT) on Belleview Avenue was less than satisfactory. In an earlier COOT micro surfacing project on 1·25, in Pueblo , IMR sublet product application to another cont,actor , with very discouraging results . While we will continue to monitor the activities of this company, we have not been impressed wtth their performance to date. Quality Resurfacing Company of Commerce City Is a newer slurry contractor in our area . This company was established in 1994, and the principals appear to have many years' experience in the general paving • industry. This company uses late model truck-mounted type eqyipment and appears to have successfully tackled several standard slurry projects during lh9 1994, 1995, 1996, 1997 and 1998 seasons. They do not have experience placing our temperamental Englewood micro-surfacing product. We will also monitor the performance of this company and may , depending on the qualtty of their work on other projects, wish to consider them for future work in Englewood . We prefer to use the only contractor that has demonstrated successful applications utilizing the products and mix designs that we have developed , and that achieve our desired results. We are satisfied with product performance to date and are particularly pleased with performance or , our local service st-eels . The contractor, BASS , Inc., is available to accomplish our 1999 project in mid May this year. Our 1999 Micro-surfacing Program will target local service and collector streets. We continue to specify micro -surfacing over standard slurry because of its flexibility of use . Slurry seal is a single thickness application product. Micro-surfacing has the capability of being applied in whatever thickness necessary to address our maintenance requirements . Micro-surfacing is used for rut filling and leveling as well as for overall roadway sealing . In early years . chemical makeup caused a 17 second break tin,e with our micro• surface specttlcatlon. Modification in product chemistry in 1993, 1994 , 1995, 1996, 1997 and 1998 increased break time to about 40 seconds. This greatly imprnved the workability of the mix while maintaining our ability to open streets to through traffic in <ll to 30 minutes, if required . Our design continues to specify the qualtty custom crushed , gray granite aggregate supplied by Asphalt Paving c~mpany , Golden, Colorado . We will continue to us9 the improved EAGON emulsion, as developtJ for our 1993, 1994, 1995, 1996, 1997 and 1998 programs . However, our specttied EAGON emulsions are no longer manufactured in the Denver Drea. In 1999 , as in 1995, 1996, 1997 and 1998, emulsions must be transported frt 11 Waco, Texas . • • • FINANCIAL IMPACT We ex~e ct that bids for standard slurry in the metro area , us ing local contractors and lower quality component~ than our spuclfications (approximately 5 hour traffic tlmAs), should range from $0 .90 to $1 .15 per square yard In 1999 . Quick set , polymer modified slurries with characteristics similar to our spdcification s (2 to 3 hour trJftic times) will likely bid at $1 .40 to $1 .50 per square yard In 1999. The City of Greeley appears to be the only F,..,r,I Range City spec ifying products slm i:ar to ours . The ir 1997 bid price was $1 .25 per square yard for qai ~• set slurry . A competitive bid for a micro-su rfacing demonstratJ-,n proje~t in 1993, in the City of Littleton , was in the $1.65 per square yard range. With our specified quality emuls ion , aggregate , and app llca1Jon equipment , our comparable coverage cost in 1993, 1994, 1995 , 1996, 1997 and 1 e~e averaged $1 .26 per square yard. Pr•liminary conversations with BASS suggest a willingness to return to Englewo od in 1999 and L'Onstruct micro-surfacing at a unit price comparable to last year's contract ($166 .02 per ton)', even though Increases in the price of aggregat e and emulsion could run 5% ov er 1998 . The 1991 co 1trac: was for $280,0l'0 (approx imately 160 ,000 square yards or 60 blocks• S1 .75 :,er square yard -and included heavy application rate on South Broadway). Funding for 1992 was limited to $260 ,0v0 for mir.ro -surf&c lng (approx imately 185,000 square yards or 70 blocks -$1 .41 per square yard). In 1993, we constructed approximately 201 ,000 square yards (76 biocks) at a cost of S305,000 -S1.52 per squ11re yard. In 1993, rut filling , surface leveling and sl ightly increased application rates generated a higher per square yard constru ction cost than our 1992 experience . Our 1994 experience was again in the $1.50 per aquare yard range , based upon 207,000 square yards of product and a ccntract price of S315 ,000. In 1995 and 1986, with major Increases In costs of materials and an approximately 20% increase in application rates to do heavy rut filling and leveling, we placed 209,000 square yards of micro-surfacing at a total cost of $339,000 -$1.62 per square yard -and 223,000 square yards at a total cost of $358,000 -S1.61 per aquare yard - respectively. In 1997, we placed 240,000 square ya rds (97 blocks) of material at a total cost of $360 ,000 • $1.58 per square yard . In 1998. we placed 214,000 square yards (90 blocks) of material at a total cost of $361 ,000 • $1.69 per square yard. This cost remains in the magnitude of 25% of the cost of aspha1tlc concrete overlay while still allowing us to correct many of the irre gularities within a structurally sound roar'way surface . Increases incurred in 1999 micro-surfac ing construction and material costs would also be reflected in construction co sts for asphaltlc concrete overlays in 1999. For the 1999 program , we recommend contracting with BASS , Inc . fo r appro xi mately 204 ,000 squa re yards of micro-surfacing at a un it price comparab !~ ;,1 that negot iated in 1998, resulting in a contract of approximately $350 ,000. $540 ,000 Is available in the Road and 1ridge PIF account for 1999 . The balance of tunding in the 1999 Road and Bridge PIF account will be utilized for asph~!tic concrete overlays by Englewood forces , and associated maintenance program admin istration , testing , ; •rogram studies and inspe ction . Add itionally, in 1999, Eng ineering will continue ongo ing discussions with BASS, Cob itco, and Koch MatA SdiS to evaluate the develupment of new slurry and micro-surfacing product desiL as , including utiliz i~,g some local asphalt products . This effort is to provide Englewo od with quality , co st effective slurry and micro-s urfac ing products for fut ure ye~rs• programs . LIST OF ATTACHMENTS Attached is a 11st of streets proposed for Inclusion in our 1999 overla y and micro -surfacing programs. They are intended to be representative of lhe proposed programs anc1 are, of course, subj ect to your review and comment. Since 1987 , we have addressed the ma intenan ce needs of some 111 miles of our approximately 120 mile roadway system . The 1999 program will add about another 11 miles to that total. Our program has , basically , addressed ou r entire street system over ~ twelve (12) year period . Many deserving maintenance candidates exist within our stree t rystem. A progressive slurry sea l/micro-surfacing program would address all of th e streets within the system over a seven year period , suggesting that the annual budge'.:~, this activity remains at approx imately 60 % of ideal funding levels. Our street syste,n remains among the best in the Denver melro area , a te stimon ial to Englewo od's street mainten ar ~e stra tegy . ' Que lo the varyinp app llcatlan rates of mic ro -surfacing , with ever ch angin g roadwAy co ndition s, micro-surfac ing is contracted by unit weight applied jtuns).
