A RESOLUTION TO WAIVE COMPETITIVE BIDDING AND AUTHORIZE A CONTRACT WITH
SWEETSER CONSTRUCTION, INC. IN THE AMOUNT OF $155,295 FOR THE CONSTRUCTION OF
DRAINAGE INLET TOPS AND INLET EXTENSIONS ASSOCIATED WITH PHASE I OF THE
SUNBRIDGE AND COLLEGE DRAINAGE PROJECT, AND TO APPROVE A PROJECT CONTINGENCY
IN THE AMOUNT OF $25,OOO.OO
WHEREAS, on August 6, 2024, the City Council authorized a contract with Tri-Star Contractors, LLC for the
construction of drainage improvements to address flooding issues near Sunbridge and College; and
WHEREAS, Tri-Star has fallen significantly behind the proposed schedule of work and, while the sanitary sewer
relocation and a good portion of the drainage has been installed, the contractor has estimated many additional months
beyond the completion date of February 10, 2026 to complete the work; and
WHEREAS, a significant portion of the remaining work involves concrete construction services, which were
previously awarded through the bulk bid process to Sweetser Construction; however, additional concrete work not
covered within the bulk bids includes 8-foot inlet extensions and construction of the tops of drainage boxes; and
WHEREAS, staff proposes authorizing Sweetser to complete the additional work concurrently with their existing bulk
bid items because, in standard construction practice, curb and gutter installation is typically completed simultaneously
with forming the inlet throat and any associated extensions; and
WHEREAS, this coordination is particularly important on project with roadway longitudinal slopes below one percent,
as is the case for many areas of this project and constructing these elements together helps ensure proper elevations,
minimizes the risk of low spots that retain water, and provides a higher quality finished product while avoiding
complications and time delays associated with mobilizing a separate contractor.
NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF FAYETTEVILLE,
ARKANSAS:
Section l: That the City Council of the City of Fayetteville, Arkansas hereby determines an exceptional situation exists
in which competitive bidding is deemed not feasible or practical and therefore waives the requirements of formal
competitive bidding and authorizes a contract with Sweetser Construction, Inc. in the amount of $155,295.00 for the
construction of drainage inlet tops and inlet extensions associated with Phase I of the Sunbridge and College Drainage
Project, and further approves a project contingency in the amount of$25,000.00.

CITY COUNCIL MEMO
2026-1280
MEETING OF APRIL 21, 2026
TO: Mayor Rawn and City Council
THROUGH: Keith Macedo, Chief of Staff
Chris Brown, Public Works Director
FROM: Alan Pugh, Stormwater Manager
SUBJECT: Approval to waive competitive bidding and approve a contract with Sweetser
Construction, Inc, the City's bulk bid provider of concrete services, in the amount of
$155,295 and a $25,000 contingency on Sunbridge and College Phase I to perform
construction of drainage inlet tops and inlet extensions
RECOMMENDATION:
Staff recommends approval to waive competitive bidding and approve a contract with Sweetser Construction,
Inc, the City's bulk bid provider of concrete services, in the amount of $155,295 and a $25,000 contingency on
Sunbridge and College Phase I to perform construction of drainage inlet tops and inlet extensions.
BACKGROUND:
This area was identified as a priority after the 2017 flooding event due to structure flooding as well as
significant property damage and street flooding. Two structures have been reported as flooding during heavy
rains, at least one additional structure has had water intrusion, and many others are receiving property damage
or at risk of flooding. Significant road flooding also occurs along N Villa Blvd E Granada St. This project was
originally designed to also alleviate flooding at the intersection of Sunbridge and College. Although the
proposed downstream improvements should help the intersection, the upstream portion of the project at
College Avenue is scheduled for a future phase due to the original bids being significantly over the available
budget.
City council approved entering into a contract with Tri-Star Contractors, LLC on August 6, 2024 to complete the
construction of the project.
DISCUSSION:
Tri-Star Contractors has fallen significantly behind the proposed schedule of work. Tri-Star’s required
completion date was February 10, 2026. While the sanitary sewer relocation and a good portion of the
drainage installed, the contractor estimated many additional months beyond the required completion date to
complete the work. Therefore, the City has taken action to remove a large portion of work from the current
contract with Tri-Star and complete that work using a combination of the City’s bulk bid process as well as City
forces. While most of the remaining items are included within the bulk bids, some items fall outside of that
process.
A significant portion of the remaining work involves concrete construction services. These services were
previously awarded through the bulk bid process to Sweetser Construction, and the City has issued a purchase
order for them to complete curb and gutter, driveways, sidewalks, and 4-foot inlet extensions. However,
Mailing address:
113 W. Mountain Street
Fayetteville, AR 72701
www.fayetteville-ar.gov
additional concrete work not covered by the bulk bids includes 8-foot inlet extensions and construction of the
tops of drainage boxes.
Staff proposes waiving competitive bidding for these remaining concrete construction services and authorizing
Sweetser Construction to complete the work concurrently with their existing bulk bid items. In standard
construction practice, curb and gutter installation is typically completed simultaneously with forming the inlet
throat (opening) and any associated extensions. This coordination is particularly important on projects with
roadway longitudinal slopes below one percent, as is the case for many areas of this project. Constructing
these elements together helps ensure proper elevations, minimizes the risk of low spots that retain water, and
provides a higher-quality finished product. It also avoids complications and time delays associated with
mobilizing an additional contractor.
This project is also complicated by the fact that it has many reverse throat inlets where the inlet box itself is
within the roadway rather than behind the back of curb. This is due to the large number of utilities located
directly behind the curbing on this project. In these instances, a portion of the top of the box also acts as the
throat (opening) of the inlet. Again, to ensure that everything is at the proper elevation and to provide the best
possible finished product, staff recommends that the reverse throat inlet tops be completed while constructing
the curb and gutter. From a timing and logistical standpoint, this is most easily accomplished by the contractor
completing the curb and gutter which is Sweetser Construction in this case.
The current estimate for Sweetser Construction to complete approximately 20 box tops and 15 throat extension
(8’ long) is $155,295 including bonds and insurance.

Appendix A General Concrete and Drainage Specifications
Cast -in -Place Concrete
Description. This item shall consist of concrete in pavements, culverts, and miscellaneous
structures, prepared and constructed in accordance with these specifications and conforming to the
lines, grades, dimensions, and designs shown on the plans. Concrete shall consist of approved
portland cement, fine aggregate, coarse aggregate, water, and any approved chemical admixtures
mixed in the proportions specified for the various classes of concrete. All concrete shall be from a
supplier approved by the Arkansas Department of Transportation.
Materials. The materials used in concrete shall conform to the requirements of ARDOT Standard
Specifications Section 802.02. Coarse aggregate gradation shall conform to the requirements for
Class A, S, S(AE), and Seal Concrete in Section 802.02.
Admixtures shall be used to improve certain characteristics of the concrete when specified on the
plans. They may also be used when requested by the Contractor and approved by the City. The
Contractor's request shall be supported with the manufacturer's certified formulation of the
proposed admixture and with sufficient evidence that the proposed admixture has given
satisfactory results on other similar work. Permission to use the admixture may be withdrawn at
any time by the City when satisfactory results are not being obtained.
Admixtures shall be approved by the City. Admixtures shall be compatible with each other, as
advised by the manufacturer. The admixture dosage rate range as recommended by the
manufacturer shall be used. Should the dosage rate for any admixture not yield desirable
characteristics in the concrete, the dosage of admixture used shall be based on test results obtained
by trial batches.
Admixtures shall be added to the mixing water by means of a mechanical dispenser that will
accurately meter the additive throughout the mix water cycle. The dispenser shall be constructed
and connected so that the Engineer/City Engineer can readily determine the amount of admixture
entering the mixing water.
Fly ash may be used as a partial cement replacement not exceeding 20% by weight of the cement
when approved by the City. When fly ash is used, the total weight of both cement and fly ash will
be used in design calculations. Fly ash used in concrete shall meet the requirements of ASTM C
618, Class C or F. Mixing of Class C and Class F fly ashes will not be permitted. Use of fly ash
shall be discontinued immediately, as directed by the Engineer/City Engineer, when such use is
determined to be causing the production of concrete that does not meet Specifications.
601.03 Classes of Concrete. One class of concrete is provided for in these specifications. The
appropriate class of concrete shall be used as specified below or where designated by the

Appendix A General Concrete and Drainage Specifications
601.06 Measurement of Materials. Materials will be measured by weighing, except as
otherwise specified or where other methods are specifically authorized by the Engineer/City
Engineer. Aggregates shall be measured separately and accurately by weight. Measuring devices
shall be operated in a manner that will consistently weigh the cement within ± 1% and the
individual aggregates within ± 2% of the required weight. Measuring devices shall be so designed
and plainly marked that the weights can be accurately and conveniently verified for the quantities
of each component actually being used.
Cement in standard packages (sack) need not be weighed, but bulk cement shall be weighed.
The mixing water shall be measured by weight or by volume. The water measuring device shall
be accurate to within 1 %.
When the aggregates contain more water than the quantity necessary to produce a saturated
surface -dry condition, representative samples shall be taken and the moisture content determined
for each kind of aggregate.
601.07 Mixing Concrete. Concrete shall be thoroughly mixed in a mixer of an approved size
and type that will insure a uniform distribution of the materials throughout the mass.
The concrete shall be mixed only in the quantity required for immediate use. Concrete that has
developed an initial set shall not be used. Re -tempering concrete will not be permitted.
Mixers and agitators shall not be charged in excess of the manufacturer's rated capacity. Concrete
shall be delivered and discharged from the truck mixer or agitator into the forms within 1 %2 hours
after the introduction of the mixing water to the cement. In hot weather, or under other conditions
contributing to quick setting of the concrete, the maximum allowable time may be reduced by the
Engineer/City Engineer. Each mixture shall be accompanied by a truck ticket issued at the batch
plant. This ticket shall include the following information:
1) Unique ticket number.
2) Identification of the truck.
3) Date and time of batching.
4) Total weights and/or volumes of each component.
5) Total volume of mix.
6) Total quantity of water added after batching.
7) Time of discharge.
Plants and transit mix trucks shall be equipped with adequate water storage and a device for
accurately measuring and controlling the amount of water used in each batch.
Truck mixers shall be capable of combining the ingredients of the concrete into a thoroughly mixed
and uniform mass, and of discharging the concrete within the specified range of consistency. The
concrete shall be mixed not less than 70 nor more than 100 revolutions of the drum or blades at
the rate of rotation specified by the manufacturer as the mixing speed. The pick-up and throw -over
Appendix A General Concrete and Drainage Specifications
blades in the drum of all mixers shall be maintained in satisfactory condition to assure thoroughly
mixed concrete.
If additional mixing water is required to maintain the specified slump, approximately 20
revolutions of the mixer drum at mixing speed shall be required before discharge of any concrete.
No additional water shall be added without approval of the Engineer/City Engineer.
601.08 Handling and Placing Concrete.
(a) General. The Contractor shall provide sufficient supervision, manpower, equipment, tools,
and materials and shall assure proper production, delivery, placement, and finishing of the concrete
for each placement in accordance with the specifications.
The time interval between batches of concrete in a continuous placement shall not exceed 20
minutes. The minimum placement rate shall be 20 cubic yards per hour in bridges, box culverts,
and retaining walls.
In preparation for the placing of concrete, construction debris and extraneous matter shall be
removed from the interior of forms. Struts, stays, and braces, serving temporarily to hold the forms
in correct shape and alignment pending the placing of concrete, shall be removed when the
concrete placement has reached an elevation rendering their service unnecessary.
(b) Conveying. Concrete shall be placed to avoid segregation of the materials and the displacement
of the reinforcement. The use of long troughs, chutes, and pipes for conveying the concrete to the
forms will be permitted only when authorized by the Engineer/City Engineer. In case an inferior
quality of concrete is produced by the use of such conveyors, the Contractor shall cease the use of
that conveyor until such corrections in procedure are made to insure work of the quality specified.
Open troughs and chutes shall be of metal or metal lined. Where steep slopes are required, the
chutes shall be equipped with baffles or be in short lengths that reverse the direction of movement.
Aluminum chutes, troughs, and pipes shall not be used for depositing concrete.
Chutes, troughs, and pipes shall be kept clean and free from coatings of hardened concrete by
thoroughly flushing with water after each run. Water used for flushing shall be discharged clear of
the structure.
When placing operations involve dropping the concrete more than 5', it shall be deposited through
approved pipes. Walls of 10" thickness or less may be placed without the use of pipes, provided
the concrete can be placed without segregation.
(c) Placing. Concrete shall be placed in horizontal layers not more than 18" thick except as
hereinafter provided. When less than a complete layer is placed, it shall be terminated in a vertical
bulkhead. Each layer shall be placed and consolidated before the preceding batch has taken initial
set to prevent injury to the green concrete and avoid surfaces of separation between the batches.
Each layer shall be consolidated so as to avoid the formation of a construction joint with a
preceding layer that has not taken initial set.
r
Appendix A General Concrete and Drainage Specifications
Concrete in footings shall be placed in the dry unless natural conditions prohibit. In that case,
concrete shall be placed in accordance with Subsection 601.10. In order to separate water from the
concrete, it will be permissible to utilize polyethylene sheeting or tarpaulins to maintain a physical
barrier between the water and the concrete.
When the placing of concrete is temporarily discontinued, the concrete, after becoming firm
enough to retain its form, shall be cleaned of laitance and other objectionable material to a
sufficient depth to expose sound concrete. To avoid visible joints as far as possible upon exposed
faces, the top surface of the concrete adjacent to the forms shall be smoothed with a trowel. Where
a "feather edge" might be produced at a construction joint, an inset form shall be used to produce
an edge thickness of not less than 6 inches.
Immediately following the discontinuance of placing concrete, accumulations of mortar splashed
upon the reinforcing steel and the surfaces of forms should be removed. Dried mortar chips and
dust shall not be puddled into the concrete. If the accumulations are not removed prior to the
concrete becoming set, care shall be exercised not to damage or break the concrete -steel bond at
or near the surface of the concrete while cleaning reinforcing steel.
After initial set of the concrete, the forms shall not be jarred and no strain shall be placed on the
ends of projecting reinforcing bars.
Concrete in walls and top slabs of box culverts shall not be placed less than 24 hours after the
concrete in previous placements has set. Provision shall be made for bonding the walls to the
bottom slab or footing and the top slab to the walls by means of roughened longitudinal keys.
Before concrete is placed in the walls or top slabs, the bottom slab, footing, or walls shall be
thoroughly cleaned of extraneous material. No horizontal construction joints will be allowed in
any wall of a box culvert unless provided on the plans or approved by the Engineer/City Engineer.
(d) Consolidating. All concrete, during and immediately after depositing, shall be thoroughly
consolidated. This shall be accomplished by mechanical vibration subject to the following
provisions:
1) The vibration shall be internal unless special authorization of other methods is given by the
Engineer/City Engineer.
2) Vibrators shall be of a type and design approved by the Engineer/City Engineer. They shall
be capable of transmitting vibration to the concrete at rated frequencies of not less than
4500 impulses per minute.
3) The intensity of vibration shall be such as to visibly affect a mass of concrete over a radius
of at least 18 inches.
4) The Contractor shall provide a sufficient number of vibrators to properly compact each
batch immediately after it is placed in the forms and shall have in reserve at all times
sufficient vibratory equipment to guard against shut down of the work because of the
failure of the equipment in operation.
5) Vibrators shall be manipulated to thoroughly work the concrete around the reinforcement
and embedded fixtures and into the corners and angles of the forms.
7
Appendix A
General Concrete and Drainage Specifications
6) Vibration shall be applied at the point of deposit and in the area of freshly deposited
concrete. The vibrators shall be inserted and withdrawn out of the concrete slowly. The
vibration shall be of sufficient duration and intensity to thoroughly consolidate the
concrete, but shall not be continued so as to cause segregation. Vibration shall not be
continued at any one point to the extent that localized areas of grout are formed.
Application of vibrators shall be at points uniformly spaced and not farther apart than twice
the radius over which the vibration is visibly effective.
7) Vibration shall not be applied directly or through the reinforcement to sections or layers of
concrete that have hardened to the degree that the concrete ceases to be plastic under
vibration. It shall not be used to make concrete flow in the forms over distances so great as
to cause segregation, and vibrators shall not be used to transport concrete in the forms.
8) Vibration shall be supplemented by such spading as is necessary to ensure smooth surfaces
and dense concrete along form surfaces and in corners and locations impossible to reach
with the vibrators.
These provisions shall apply to precast products except that, if approved by the Engineer/City
Engineer, the manufacturer's methods of vibration may be used.
601.09 Pumping. Concrete may be placed by pumping. The equipment for pumping shall be
arranged and operated so that no vibrations result that might damage freshly placed concrete.
The Contractor will be permitted to furnish coarse aggregate for concrete that is to be pumped in
a size smaller than that specified provided that a suitable mix can be produced that will conform
to the requirements for the class specified.
Where concrete is conveyed and placed by mechanically applied pressure, the equipment shall be
adequate in capacity for the work. The operation of the pump shall be such that a continuous stream
of concrete without air pockets is produced. When pumping is completed, the concrete remaining
in the pipe, if it is to be used, shall be ejected in such a manner that there will be no contamination
of the concrete or separation of the ingredients.
Concrete for slump and air content requirements shall be obtained at the discharge end of the pipe.
The use of aluminum pipe as a conveyance for the concrete will not be permitted.
601.10 Depositing Concrete Under Water. Concrete shall not be deposited in water except
when shown on the plans or with the approval of the Engineer/City Engineer. No concrete shall be
placed underwater without an approved mix design which meets the ARDOT requirements for
Seal Concrete.
The supply of concrete shall be maintained at the rate necessary to raise the elevation over the
entire seal by a minimum of P per hour or an approved retarder shall be used as necessary for
lesser placement rates.
8
Appendix A General Concrete and Drainage Specifications
For parts of structures under water, seal concrete shall be placed continuously from start to finish.
The surface of the concrete shall be kept as nearly horizontal as practicable. The Contractor shall
provide equipment and personnel to sound the top of the seal in the presence of the Inspector in
order to verify the location of the seal at all times. Previously placed seal concrete shall not have
taken its initial set prior to the placement of adjacent concrete.
Concrete shall be carefully placed by means of a tremie or other approved method. Still water shall
be maintained at the point of deposit. Concrete shall be deposited in such a manner that the planned
horizontal concrete flow shall be no more than 15 feet.
A tremie shall consist of a tube having a diameter of not less than 10", constructed in sections
having flanged couplings fitted with gaskets and an approved foot valve. The tremie shall be
supported so as to permit rapid lowering when necessary to retard or stop the flow of concrete.
The discharge end shall be closed at the start of the work so as to prevent water from entering the
tube and shall be entirely sealed. The tremie tube shall be kept sufficiently full to prevent the loss
of the concrete seal. When a batch is dumped into the tube, the flow of concrete shall be induced
by slightly raising the discharged end, always keeping it in the deposited concrete. If at any time
the seal is lost, the tremie shall be raised, the discharge end closed for a new start, and then lowered
into position with the discharge end in the previously deposited concrete. Aluminum tremies will
not be permitted.
Dewatering may proceed when the seal concrete has been allowed to cure for a minimum of 72
hours at a water temperature above 45' F. All laitance or other unsatisfactory materials shall be
removed from the exposed surfaces that are to support other structural loads.
601.11 Joints.
(a) Construction joints. Construction joints shall be made only where located on plans or shown
in the placement schedule, unless otherwise approved by the Engineer/City Engineer.
The placing of concrete shall be carried continuously from joint to joint. The face edges of all
joints that are exposed to view shall be carefully finished true to line and elevation.
The surface of the hardened concrete shall be roughened in a manner that will not leave loosened
particles of aggregates or damaged concrete at the surface. It shall be thoroughly cleaned of foreign
matter and laitance and saturated with water.
If not detailed on the plans, or in the case of emergency, construction joints shall be placed as
directed by the Engineer/City Engineer. Shear keys or inclined reinforcement shall be used where
necessary to transmit shear or bond the two sections together. When shear keys or inclined
reinforcement is not provided, the concrete shall be roughened as directed.
(b) Expansion and Fixed Joints. Joints shall be constructed according to the details shown on the
plans.

Type 7. A joint sealer that is a hot poured elastic type complying with AASHTO M 173.
601.12 Forms. Forms shall be mortar -tight and of sufficient rigidity to prevent distortion due to
the pressure of the concrete and other loads incident to the construction operations. Forms shall be
constructed and maintained so as to prevent warping and the opening of joints due to shrinkage of
the lumber.
The forms shall be substantial and unyielding and shall be so designed that the finished concrete
will conform to the proper dimensions and contours. The design of the forms shall take into
account the effect of vibration of concrete as it is placed.
Forms for exposed surfaces shall be made of dressed lumber or plywood of uniform thickness,
steel, or other approved materials that will provide a smooth surface, and shall be mortar -tight.
Forms shall have a 3/4" chamfer at all sharp corners unless otherwise directed. In the case of

11
Appendix A General Concrete and Drainage Specifications
be re -tightened. Forms shall remain in place for the periods specified in Subsection 601.13. When
forms appear to be unsatisfactory in any way, either before or during the placing of concrete, the
Engineer/City Engineer shall order the work stopped until the defects have been corrected.
The shape, strength, rigidity, watertightness, and surface smoothness of re -used forms shall be
maintained at all times. Any warped or bulged lumber must be re -sized before being re -used.
Forms shall be cleaned before being set to line and grade and shall be oiled prior to placing
reinforcing steel in the vicinity of the forms. Materials or methods used in oiling the forms shall
not result in the discoloration of the concrete.
601.13 Removal of Forms. In the determination of the time for the removal of forms and the
discontinuance of heating, consideration shall be given to the location and character of the
structure, the weather and other conditions influencing the setting of the concrete, and the materials
used in the mix.

removed at the earliest time permitted under these Specifications in order to begin finishing
operations.
Forms and their supports shall not be removed without the approval of the Engineer/City Engineer.
Supports shall be removed in such a manner as to permit the concrete to uniformly and gradually
take the stresses due to its own weight. Methods of form removal likely to cause overstressing of
or damage to the concrete shall not be used.
601.14 Weather and Temperature Limitations.
(a) Hot Weather. When the internal temperature of the plastic concrete reaches 85' F, the
Contractor shall take the necessary precautions to ensure that the temperature of succeeding
batches does not exceed 90' F. Concrete batches with temperatures in excess of 901 F will be
rejected. The method used to control the concrete temperature shall be approved in writing by the
Engineer. The temperature of the plastic concrete shall be determined immediately prior to its
being deposited in the forms by inserting a thermometer to a depth consistent with the capabilities
of the thermometer being used to obtain a true reading. Prior to beginning placement, the
Contractor shall insure that sufficient materials, labor, and equipment are available during
placement to implement the previously approved cooling process.
12
Appendix A General Concrete and Drainage Specifications
(b) Cold Weather. Concreting operations will not be permitted when a descending air temperature
falls below 40' F nor resumed until an ascending air temperature reaches 35° F without specific -
authority from the Engineer/City Engineer. Under no circumstances will the placing of concrete
on a frozen subgrade be permitted. No concrete shall be placed unless the temperature of the
concrete is more than 50' F when placed. If heating of the ingredients is necessary to meet this
criterion, it shall be accomplished by a method such as dry heat or steam and not by direct flame.
Water shall not be heated to more than 180` F, and shall be combined with the aggregate before
the addition of cement. Frozen aggregates may not be used.
After concrete is placed, it shall be protected by insulated forms, blankets, enclosing and heating,
and/or any other method approved by the Engineer/City Engineer that will maintain the
temperature adjacent to the concrete at a minimum of 50' F for at least 5 days. Concrete that has
been frozen or damaged due to weather conditions shall be removed and replaced by the Contractor
at no cost to the City.
(c) Protection Against Rain. In order that concrete may be properly protected against the effects
of rain before the concrete is sufficiently hardened, the Contractor shall have available at all times
materials for the protection of the edges and surface of the unhardened concrete. Such protective
materials shall consist of standard metal forms or wood planks having a nominal thickness of not
less than 2" and a nominal width of not less than the thickness of the pavement at its edge for the
protection of the pavement edges, and covering material such as burlap or cotton mats, or plastic
sheeting material for the protection of the surface of the pavement. When rain appears imminent,
all paving operations shall stop and all available personnel shall begin protection of the sides of
the pavement and covering the surface of the unhardened concrete with the protective covering.
Any surface finish damaged by rain shall be repaired or replaced to the satisfaction of the City at
no cost to the City.
601.15 Curing Concrete.

(b) Application. The exposed concrete, immediately after finishing, shall be covered with one of
the curing materials listed above and shall be kept continuously and thoroughly wet for a period
of not less than 5 days after the concrete is placed. Membrane curing does not require the
application of additional moisture.
Membrane curing compound shall not be used on surfaces requiring a Class 2 finish.
When membrane curing is used, the exposed concrete shall be thoroughly sealed by applying the
membrane curing solution immediately after the free water has left the surface. The concrete inside
the forms shall be sealed immediately after the forms are removed and necessary finishing has
been done. For uniform application in the field on vertical concrete surfaces, the specified rate of
application may be achieved by two coats applied at an interval of approximately 1 hour.
The Contractor shall provide satisfactory equipment and means to properly control and assure the
direct application of the curing solution on the concrete surface so as to result in a uniform
coverage at the rate of 1 gallon for each 125 square feet of area.
If rain falls on the newly coated concrete before the film has dried sufficiently to resist damage, or
if the film is damaged in any other manner, a new coat of the solution shall be applied to the
affected portions equal in curing value to that specified above.
601.16 Finishing Concrete Surfaces. Surface finishes shall be classified as follows:
Class 1.
Ordinary Surface finish.
Class 2.
Rubbed finish.
Class 3.
Sprayed finish.
Class 4.
Exposed Aggregate finish.
Class 5.
Tined Surface finish.
Class 6.
Broomed finish.
Class 7.
Grooved finish.
All concrete shall be given a Class 1, Ordinary Surface Finish. In addition, if further finishing is
required, such other types of finish will be as specified herein.
Payment for finishes will be considered a part of the applicable item of concrete used.
The following surfaces shall be given a Class 2 finish except when a Class 3 finish is specified in
the plans:
1) Exposed surfaces of retaining walls and box culvert wingwalls, surfaces of concrete rails,
rail posts, rail end posts, rail bases, and parapets, including the outside face.
2) At the option of the Contractor, a Class 3 finish may be used on all surfaces requiring a
Class 2 finish provided the same class of finish is used on the entire job.
3) Sidewalks, curbs, exposed horizontal surfaces of inlets and junction boxes, and exposed
horizontal faces of miscellaneous concrete items shall be given a Class 6 finish.
14
Appendix A
General Concrete and Drainage Specifications
4) Concrete pavement surfaces shall be given a Class 5 finish.
The various classes of surface finish are defined as follows:
(1) Class 1, Ordinary Surface Finish. Immediately following the removal of forms, fins and
irregular projections shall be removed from all surfaces except from those that are not to be
exposed or are not to be waterproofed. On all surfaces, the cavities produced by form ties and all
other holes, broken corners or edges, and other defects shall be thoroughly cleaned, and after
having been thoroughly saturated with water, shall be carefully pointed and trued with a mortar of
cement and fine aggregate mixed in the proportion of 1:2. Mortar used in pointing shall be not
more than 1 hour old. The concrete shall then be rubbed or sprayed, if required, and cured as
specified under Subsection 601.15. Construction and expansion joints in the completed work shall
be left carefully tooled and free of mortar and concrete. The joint filler shall be left exposed for its
full length with clean and true edges.
The resulting surfaces shall be true and uniform. Repaired surfaces, the appearance of which is not
satisfactory to the City, shall be rubbed as specified under Class 2 finish.
Exposed surfaces not protected by forms shall be struck off with a straightedge and finished with
a wood float to a true and even surface. The use of additional mortar to provide a plastered or grout
finish will not be permitted.
The tops of caps in the area of the bridge seat shall be finished with a steel trowel or by grinding
to a smooth finish and true slope at the proper elevation.
(2) Class 2, Rubbed Finish. After removal of forms, the rubbing of concrete shall be started as
soon as its condition will permit. Immediately before starting this work the concrete shall be
thoroughly saturated with water. Sufficient time shall have elapsed before the wetting down to
allow the mortar used in the pointing of rod holes and defects to thoroughly set. Surfaces to be
finished shall be rubbed with a medium coarse carborundum stone, using a small amount of mortar
on its face. The mortar shall be composed of cement and fine sand mixed in proportions used in
the concrete being finished. Rubbing shall be continued until form marks, projections, and
irregularities have been removed, voids filled, and a uniform surface has been obtained. The paste
produced by this rubbing shall be left in place at this time.
After concrete above the surface being treated has been cast, the final finish shall be obtained by
rubbing with a fine carborundum stone and water. This rubbing shall be continued until the entire
surface is of a smooth texture and uniform color.
After the final rubbing is complete and the surface has dried, it shall be rubbed with burlap to
remove loose powder and shall be left free from all unsound patches, paste, powder, and
objectionable marks.
(3) Class 3, Sprayed Finish. The material furnished for sprayed finish shall be a commercial paint
type texturing product produced specifically for this purpose, and shall consist of a synthetic non-
15
Appendix A General Concrete and Drainage Specifications
alkyd resin containing mica, perlite, non -biodegradable fibers, and durable tinting pigments. The
material shall be approved by the City. Unless otherwise specified in the Contract, the color of the
sprayed finish shall be concrete gray, equal or close to Shade 36622 of the Federal Color Standard
595 A.
Surfaces to be coated shall be free from efflorescence, flaking, coatings, dirt, oil, and other foreign
substances. The sprayed finish shall not be applied over surfaces cured with membrane curing
compound until 30 days has elapsed from application of the membrane. Prior to application of
spray finish, the surfaces shall be free of moisture, as determined by sight and touch, and in a
condition consistent with the manufacturer's published recommendations.
The spray finish shall be applied at a rate as recommended by the manufacturer and as approved
by the Engineer/City Engineer. The spray finish shall be applied with heavy duty spray equipment
capable of maintaining a constant pressure as necessary for proper application.
The completed finish shall be tightly bonded to the structure and shall present a uniform
appearance and texture equal to or better than that required for rubbed finish. If necessary, an
additional coat or coats shall be applied to produce the desired surface texture and uniformity.
Upon failure to adhere positively to the structure without chipping or cracking, or to attain the
desired surface appearance, the coating shall be removed from the structure and the surface given
a rubbed finish, or another approved finish satisfactory to the City.
(4) Class 4, Exposed Aggregate Finish. This type of finish shall be produced by scrubbing the
surface of green concrete with stiff wire or fiber brushes, using a solution of muriatic acid in the
proportion of 1 part acid to 4 parts water, or by sand blasting, until the cement film or surface is
completely removed and the aggregate particles are exposed. The amount of aggregate exposure
will be specified on the plans or designated by the Engineer/City Engineer. Any surface treated
with muriatic acid shall be thoroughly washed with water to which a small amount of ammonia
has been added to remove all traces of the acid. The resulting surface shall be an even pebbled
texture.
(5) Class 5, Tined Roadway Surface Finish. The concrete roadway surface shall be given a finish
with a burlap drag, followed by tining.
The surface shall be finished by dragging a seamless strip of damp burlap over the full width of
the roadway surface. The burlap drag shall consist of sufficient layers of burlap and have sufficient
length in contact with the concrete to slightly groove the surface, and shall be moved forward with
a minimum bow of the lead edge. The drag shall be kept damp, clean, and free of particles of
hardened concrete.
The final finish shall be accomplished by using the drag finish as described above with the further
application of a metal tine finishing device. The tine shall be approximately 0.032" by 0.125" of
steel flat wire, 2" to 5" in length, and spaced on %2" to 3/4" centers. The grooves produced in the
concrete shall be substantially from 1/8" to 3/16" in depth. The grooves shall be transverse to the
centerline of the surface. The metal tine device shall be operated by approved mechanical or
16
Appendix A General Concrete and Drainage Specifications
manual means. Other texturing equipment may be approved by the Engineer/City Engineer
provided it produces a texture equivalent to that produced by the metal tine.
The tining shall be terminated with a transition in depth 18" from the gutter line. The outer 18" of
the tined surface shall receive a Class 6, broomed finish.
(6) Class 6, Broomed Finish. After the concrete has been deposited in place, it shall be
consolidated and the surface shall be struck off by means of a strike board, floated, and broomed.
An edging tool shall be used on edges and expansion joints. The surface shall not vary more than
'/4" under a 10' straightedge. The surface shall have a granular or matte texture.
(7) Class 7, Grooved Finish. The roadway surface shall be grooved perpendicular to the centerline
with grooves extending across the slab to within 18" of the gutter line. The grooves shall be cut
using a mechanical sawing device that will leave grooves 1/8" to 3/16" in depth and spaced on %"
to 1/4" centers.

Sunbridge and College Drainage Improvements Phase I
RECOMMENDATION:
Staff recommend the mayor sign Change Order #1 with Sweetser Construction in the amount of
$16,500 for the addition of concrete paving, ditch paving, combination inlet and concrete collar
necessary for the completion of the Sunbridge and College Drainage Improvements Phase I
BACKGROUND:
This area was identified as a priority after the 2017 flooding event due to structure flooding as
well as significant property damage and street flooding. Two structures have been reported as
flooding during heavy rains, at least one additional structure has had water intrusion, and many
others are receiving property damage or at risk of flooding. Significant road flooding also occurs
along N Villa Blvd E Granada St. This project was originally designed to also alleviate flooding
at the intersection of Sunbridge and College. Although the proposed downstream improvements
should help the intersection, the upstream portion of the project at College Avenue is scheduled
for a future phase due to the original bids being significantly over the available budget.
City council approved entering into a contract with Tri-Star Contractors, LLC on August 6, 2024
to complete the construction of the project. After Tri-Star contractors fell behind with the
proposed schedule of work, a portion of the work was proposed to be completed by City crews
as well as Sweetser Construction through both a waiver of bidding and the bulk bid process.
DISCUSSION:
The proposed change order is a modification to the bid waiver contract with Sweetser
Construction in order to complete additional work necessary for the project not included in the
bulk bid process. As noted in the bid waiver, staff propose the work be performed by Sweetser
construction concurrently with their existing bulk bid items. In standard construction practice,
curb and gutter installation is typically completed simultaneously with forming the inlet throat
(opening) and any associated extensions. This coordination is particularly important on projects
with roadway longitudinal slopes below one percent, as is the case for many areas of this
project. Constructing these elements together helps ensure proper elevations, minimizes the
2
risk of low spots that retain water, and provides a higher-quality finished product. It also avoids
complications and time delays associated with mobilizing an additional contractor.
Council approved a $25,000 contingency along with the bid waiver and the proposed change
order is less than the contingency amount.
BUDGET/STAFF IMPACT:
Funding will come from the 2022 Drainage Bond Fund
