Subject Resolution to Negotiate

IS.5UE/ ACTION PROPOSED
Staff seeks Council approval of a Resolution allowing a negotiated contract (an exception to
the competitive bid process) and awarding a negotiated contract in an amount not to exceed
$315,000 to oituminous Asphalt Sealing Specialists, Inc. (BASS), of North Little Rock,
Arkansas, fo r Englewood's 1994 Micro-surfacing Program.
PREVIOUS COUNCIL ACTION
Resolution No. 39, Series of 1993, Resolution No. 52, Series of 1992, and Resolution No. 39 ,
Series of 1991, approving negotiating contracts and awarding negotiated contracts for the
1993, 1992, and 1991 Micro-surfacing Programs respectively.
BACKGROUND
The annual Public Improvement Fund allocation for contract street maintenance, primarily
slurry seal and micro-surfacing, has averaged $267,000 since 1987. For the past seven years,
the City has negotiated with BASS, Inc . to construct our slurry and micro-surfacing
programs. BASS has now placed a total oi 1,100,000 square yards of our design products
(approximately 450 blocks, or 56 miles of roadway).
Bids for standard slurry in the metro area, with local contractors and lower quality
components than our specifications, should range from $0.80 to $1.00 per square yard in
1994. A competitive bid for a micro-surfacing demonstration project in 1993, in the City of
Littleton, wa s in the $1.65 per square y ard range . With our specified quality emulsion,
aggregate, and application equipment, our costs in 1993 were approximately $1 .50 per
square yard .
STAFF ANALYSIS
Staff continues to monitor slurry seal and micro-surfacing activities in the metro area. The
workmanship of BASS, particularly with micro-surfacing , appears to remain s uperior .
Much ,.iconsi stency exi r,ts in the mix designs used by others in the metro area . We are
seeing many jurisdictions returning to s pecifying the gray grz.nite aggregate that we have
recommended and specified since 1987 . Many other user agencies are again modifying th eir
specifications for 1994, suggesting tha t they are still experimenting and not completely
satisfied with earlier products . Most micro-slll'facing products placed by others during 1992
and 1993 appear at this time to be achieving only marginally satisfactory results; we have
noted areas of localized fai lure . Wnile it is too ear ly to fully evaluate the 1993
micro-surfacing test programs by others, we do know tllat the City of Littleton is holding
off on additional micro-surfacing for 1994, pending a longer evaluation period for their 1993
product.
Throughout our seven year eJCperience wi th "Englewood " slurry, micro-surfacing , and BASS,
Inc ., citizen response continues to onl y q1•.estion our not including more streets in our
annual micro-surfacing programs . Minimal inconvenie t1 ce J u.ing construction (our traffic
ready times have remained under 2 hours) and product quality appears to meet th e
expectation of our citizenry. The extended pavement longevity for slurry and
micro-surfacing applications continues to look promising . Staff is satisfied with our
product's performance to date .
•
Staff introduce d "Englewood " micro-surfacing in 1991. Our objecti ve was to develop a •
maintenance alternati ve to address th e mainte.1ance needs ,,f roadways subjected to
excessive traffic volumes re sulting in pavement rutting and lanes requiring leveling
treatments alo ng with new wearing courses and surface seals . BASS, Inc . has successfull y
constructed micro-surfacing on selected arterials, collectors, industrial and local service
streets in our 1991 , 1992, and 1993 micro-surfacing programs. Micro-surfacing requires
highly specialized construction equipment. From our last three years experience, we know
that the use of continuous micro-surfacing equipment produces a superior product
compared to that applied with truck mounted type rnad,ines . Truck mounted equipment
was used in the construction of our earlier slurr:1 products . Continuous micro-surfacin g
equipment can apply standard slurry products . Standard slurry machines are not capable
of appl ying micro-surfaci ng. The number of continuous micro-surfacing machines
continues to grow throughout the country . BASS, Inc . owns and operates 2 of these
machines . Vance Bros., of Karisas , does own simi lar equipment and ha s estab li shed a
Denver office. However, the success of th eir 1993 Littleton demonstration project is yet to
be determined . Additionally, Vance Br os. was just rec entl y advertising for equipment
operators for the 1994 constructio'., ~eason . We prefer to use the experienced operators
emplo} ed by BASS, Inc . We wi!J continue to monitor the performance of Vance Bros . We
may cons id er them fo r futur e years w,,rk, depending upon theii: performance on other
proje cts.

. BASS, Inc. continues lo be the only proven contractor available in our area w ith
demonstrated successful applications utilizing the Ergon products and mix designs that we
have developed, and that achieve our desired results. We have confidence that thi3
specialized contractor, with whom we have seven years of progressive successful
experience, can accomplish our 1994 project lo our satisfaction in a timely and cost effective
manner. The equipm ent necessary to accomplish our 1994 project is available in late May
or early June .
Our 1994 micro-s urfacing program will target local service and minor collector streets. We
continue to specify micro-surfacing over standard slurry because of its flexibility of use.
Slurry seal is a si ngle thickness application prodt.ct. Micro-surfacing ha s the capability of
being applied in wh atever thickness is necessary to address our maintenan ce requirement.
Micro-surfacing is used for rut filling and leve ling as well as for overall roadway sealing.
In early years, chemical makeup caused a 17 second break time with our micro-surface
specification . Modification in product chemistry in 1993 increased break time to abo ut 40
seconds. Thi s greatly improved the workabili ty of the mix while maintaining our ability to
open streets to through traffic in 20 to 30 minutes, if required .
Our design will continue to specify the quality gray granite aggregate from Asphalt Paving
Company, Golden, Colorado. We will continue to use the improved Ergon emul sion, as
developed for our 1993 p rogram .
FINANCIAL IMPACT
$400 ,000 is available in the Public Improvement Fund, Road a nd Bridge acconnt of 1994.
Prel iminary conversations with BASS, Inc . sugp-,est a willingness to return to Englewood in
1994 and construct mi cro-surfaci ng at a unit price si mil ar to that in our 1991, 1992, and 1993
contracts ($152 .18 per ton). The 1991 contract was for $280,000 (a pproxi mately 160,000
square yard s , or 60 blocks ). Funding for 1992 was limited to $260,000 for micro-surfacing
(approximately 185,000 sq uare yard s, or 70 blocks). In 1993, we constructed approximately
201,000 square yards (76 blocks) at a cost of $305,000 . In 1993, rut filling , surface leveling
and slightly increased application rates, generated a per square construction cost of
1pproxi matP!y $1.50 . Whi le an increase from our 1992 experience of $1.37 per square yard,
this ,.._~t remains in the ma nitude of 40 % of the cost of asphaltic concrete overlay while
still allowing us to correct many of the irregularities within a structurall y sound roadway
surface.
For 1994, we are recommendi ng a contract with BASS, Inc. for approximately 207,000 square
yards of micro-s urfacing (80 bl ocks -approximately 10 miles of Englewood streets). At a
unit price si milar to that negotiated in 1991 , 1992, and 1993, this would result in a contract
in the $315 ,000 range. The balance of funding in th e 1993 Road and Bridge PlF account will
be utili zed for as phaltic concrete overlays by Englewood forces, and associated maintenance
program administration, te~ting, and inspection .
ote: Due to the varying application rates of micro-surfacing, w'th ever changi ng roadway
conditions, micro-surfacing is contracted by unit weight a pplied (tons).
OIHER
The attached lists of streets and avenues proposed for inclusion in our 1994 overlay and
micro-surfacing programs are for your information . It is intended to be representative of
the proposed programs and is, of course, ~abj ect or your review and comment. Since 1987,
we have addressed the maintenance needs of some 55 miles of our approximately 120 mile
roa dway system . The 1994 program will add about another 10 miles to that total.
Consequently, many deserving maintenance candidates exist within our street sys tem. A
progressive slurry seal /micro-surfacing program would address all of the streets with the
system over a seven year period , sugr ~ting that the annual budget for this activity remains
at 45 % of ideal funding le,·els .
