Mailing address: 113 W. Mountain Street Fayetteville, AR 72701 www.fayetteville-ar.gov 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.

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 Engineer/City Engineer. 3 Appendix A General Concrete and Drainage Specifications The following requirements shall govern unless otherwise shown on the plans: Class 1 concrete shall be used in curb and gutter, sidewalks, drop inlets, junction boxes, box culverts, bridges, concrete pavement, and miscellaneous concrete items. This class of concrete shall not be used if concrete is to be placed underwater. Concrete to be placed under water shall meet ARDOT Specifications for Seal Concrete. 601.04 Classification and Proportioning. The concrete mixture shall be proportioned to insure a workable and durable concrete, as specified in the following table: Characteristic Class 1 Minimum Compressive Strength (psi at 28 days) 4000 Minimum Cement Content ( bags per cu. � d.) 6 Maximum Water/Cement Ratio 0.45 Slump Range (Inches) 1-4* Air Content Range (%) 4-7 Maximum Flv Ash Content 20% *Maximum slump shall be 2" when slip form paving methods are used. For all classes of concrete, the concrete materials shall be using the Absolute Volumes method in accordance with the requirements for the class specified. The Contractor shall submit a mix design meeting the requirements of these Specifications. Certification that all materials used in the concrete mix meet the requirements of these Specifications shall be included with the mix design. No concrete shall be placed until a mix design is approved by the City. Compressive strengths for all classes of concrete will be determined from test cylinders made in accordance with AASHTO T 23. If the strength required for the class of concrete being produced is not obtained with the minimum cement content specified, additional cement shall be used at no extra cost to the City. 601.05 Sampling and Testing. During the progress of work, concrete test specimens will be made by the City or its authorized representative in accordance with American Concrete Institute testing procedures. Sampling frequency will be as specified in Section 107. Slump will be determined using AASHTO T 119. Air content will be determined using AASHTO T 152. Compressive strength specimens will be made in accordance with AASHTO T 23 and tested in accordance with AASHTO T 22. Specimens for determining when forms may be removed, when a structure may be put in service, or when concrete piling may be driven will be cured, as nearly as practicable, in the same manner as the concrete in the structure and in accordance with AASHTO T 23. 4 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. 0 Appendix A General Concrete and Drainage Specifications 1) Open Joints. Open joints shall be placed in the locations shown on the plans and shall be constructed by the insertion and subsequent removal of a wood strip, metal plate, or other approved material. The insertion and removal of the template shall be accomplished without chipping or breaking the corners of the concrete. Reinforcement shall not extend across an open joint unless specified on the plans. 2) Filled Joints. Poured expansion joints shall be constructed similar to open joints. When premolded types are specified, the filler shall be in the correct position when the concrete on the second side of the joint is placed. An approved joint sealer meeting the requirements of Subsection 601.11(d) is required in addition to the joint filler. The cavity for the sealer shall be formed by the insertion and subsequent removal of a wood strip, metal plate, or other approved material. All faces of the joint to be sealed shall be thoroughly cleaned by sand blasting, water blasting, or other approved methods prior to placing the joint seal material. Preformed expansion joint filler, non -extruding and resilient types, shall meet the requirements of AASHTO M 153. Type 2 (sponge rubber) shall be required to have a minimum expansion of 125% and be within ± 0.1" of the specified plan thickness. Other types of joint fillers may be allowed if approved by the Engineer/City Engineer. (c) Contraction Joints. Contraction joints shall be constructed according to the dimensions specified in the plans and these specifications. The joints shall continue continuously across the full width of the concrete surface. Contraction joints shall be 1/8" to 3/8" wide and shall extend to a depth equal to'/a to 1/3 of the thickness of the concrete being placed. All contraction joints shall be sealed with an approved sealant meeting the requirements of Subsection 601.11(d) for types 3, 4 or 5. (d) Joint Materials. Materials for filling and sealing joints shall be as shown on the plans and shall comply with the following requirements, as applicable: Type 1. A joint filler that is a uniform mixture of sawdust and asphalt material in the proportion of one part asphalt to four parts sawdust, by volume. Asphalt material used shall be either MC-250 or SS-1. When this material is specified, the joint shall be filled to within 25 min (1") of the pavement surface. The top 1" shall be sealed with a material complying with the requirements of AASHTO M 173. Type 2. A joint filler that is preformed, non -extruding, and resilient type, complying with AASHTO M 153 Type I (sponge rubber). The material for filling and sealing longitudinal, warping, contraction, and other specified joints shall be as shown on the plans and shall comply with the following requirements: 1) Backer rod filler for Types 3, 4, and 5 joint shall be of resilient material approximately 3 mm (1/8") larger in diameter than the width of the joint to be sealed. All components of 10 Appendix A General Concrete and Drainage Specifications the joint sealant system, including the backer rod, shall be compatible. No bond shall occur between the backup material and the sealant system for types 3 and 4 joint sealer. Type 3. A joint sealer that is a one part silicone formulation that does not require a primer for bond to concrete. The compound shall be compatible with concrete. Acetic acid cure sealants are not acceptable. The material shall be one that has been approved by the Engineer. Type 4.

A joint sealer that is a 2 component, cold poured, synthetic polymer, complying with ASTM D 1850 with the exception of penetration, which shall not exceed 100, and resilience, both original cured sample and oven aged, which shall be a minimum of 70%. 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 projections, such as girders and copings, forms shall be given a bevel or draft to insure easy removal. Metal snap -ties within the forms shall be so constructed as to permit their removal to a depth of at least 1" from the face of the concrete. Metal inserts or anchorages within the forms shall be so constructed as to permit their removal to a depth of at least 1" from the face of the concrete or be covered by being embedded a minimum of 1" in the concrete. In case ordinary wire ties are permitted, all wires, upon removal of the forms, shall be cut back at least '/4" from the face of the concrete. All cavities shall be filled with cement mortar and the surface left sound, smooth, even, and uniform in color. Forms shall be set and maintained true to the line designated until the concrete is sufficiently hardened. Before depositing new concrete on or against concrete that has hardened, the forms shall 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. Removal of forms shall be in accordance with the following schedule: Item Minimum Time Strength Requirement Top Slabs of RC Box Culverts 7 da�,s 80% Specified Forms for Columns and 24 hours N /A Vertical Walls Side Forms for Parapets, Median 6 hours N/A Barriers, and Curb Faces Forms on surfaces that will require a Class 2 finish in accordance with Subsection 601.16 shall be 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. (a) Materials. Materials used in curing concrete shall conform to one of the following types: Burlap -polyethylene sheeting shall meet the requirements of AASHTO M 171. Polyethylene sheeting shall meet the requirements of AASHTO M 171. Copolymer/synthetic blanket shall meet the requirements of AASHTO M 171. Copolymer/synthetic blankets shall be a composite of a copolymer membrane material coated over a layer of absorbent nonwoven synthetic fabric weighing at least 6 ounces per square yard, uniform in appearance, and free from visible defects. Other approved sheeting materials shall meet the requirements of AASHTO M 171. Membrane curing compound shall meet the requirements of AASHTO M 148, Type 1-1) or Type 2. 13 Appendix A General Concrete and Drainage Specifications (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. 17 Appendix B Standard Steel Specifications Section 602.

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.
