ATTENTION CONCRETE CONTRACTORS
In the past, Englewood contractors have been required to saw the asphalt 12 inches from the lipline to allow adequate space for concrete forms and proper asphalt patching. This may no longer be required where the asphalt edge is in good condition and is maintained during removal and replacement of the curb and gutter, and thus providing an acceptable finishing edge for the new concrete. The City inspector will make this determination. In the event the asphalt line is in poor condition, or a good line cannot be maintained, the City will assess a four dollar ($6.90) per linear foot charge, and the contractor will be required to saw cut the asphalt 12 inches from the lipline. Prior to patching, it shall be the responsibility of the contractor to clean this area for patching to avoid an additional four dollar ($6.90) per linear foot charge.
If the sawed edge is damaged after removal of the forms, a new saw cut will be necessary to maintain a straight edge.
Barricades are to remain in place to protect the concrete as well as the asphalt edge. The City will patch the asphalt as soon as the concrete has cured sufficiently, generally within five to seven days.

4.05 Proportioning of Materials.
A. Mixed Proportions. The actual proportions of all materials entering into the concrete mixture shall be determined by the Contractor within the limits set forth above and shall be submitted to the Engineer for approval prior to the placement of any concrete. The proportions shall be changed whenever necessary to maintain the workability, strength and standard of quality required for the concrete covered by these specifications, and to meet the varying conditions encountered during the construction. The fine aggregate and coarse aggregate shall be measured separately for each batch of concrete. The cement shall be in contact with the aggregate no longer than forty-five (45) minutes before being deposited in the mixer.
B. Measurement. The Contractor shall provide the equipment necessary to measure and control the amount of each material in each batch of concrete . All aggregates shall be mechanically batched and measured by weight. Bulk cement shall be weighted, but cement in unopened bags as packed by the manufacturer may be used without weighing. If bagcement is used, batches shall be proportioned so that fractional bags will not be required. One bag of Portland cement will be considered as ninety-four (94) pounds. Mixing water and air-entraining admixtures may be measured by volume or by weight. One gallon of water will be considered to weigh 8.33 pounds.
4.06 Batching Plant .
A. General. Separate bins or compartments shall be provided for the different sizes of aggregates to be batched and for bulk cements when used. The compartments shall be of ample size and so constructed that the materials will be kept separated under all working conditions. The plant shall be capable of ready adjustment to compensate for the varying moisture contents of the aggregates, and to change the weights of the materials being batched.
B. Weighing of Materials. Aggregates may be weighed in separate weighbatchers with individual scales, or cumulatively in one weigh-batcher on one scale . Bulk cement shall be weighted on a separate scale in a separate weigh-batcher. Water may be measured by weight or by volume .
The plant shall be arranged so as to facilitate the inspection of all operations at all times. Weighing of materials from the batching equipment shall be within the following limits of accuracy:
Material Cement
Per Cent 1
Water 1 Aggregate 2 Air-Entraining Admixture 3
C. Water-Batcher. A suitable water-measuring device shall be provided that will be capable of measuring the mixing water within the specified requirements for each batch. The mechanism for delivering water to the mixers shall be such that leakage will not occur when the valves are closed. The filling and discharge valves for the waterbatcher shall be so interlocked that the discharge valve cannot be opened before the filling valve is full closed.
D. Dispenser. A suitable device for measuring and dispensing the airentraining admixture shall be provided. The device shall be capable of ready adjustment to permit varying the quantity of admixture to be batched . The dispenser for air-entraining admixtures shall be so designed as to permit discharge into the water-discharge lines . The air-entraining admixture shall be discharged simultaneously with discharge of the water into the batch. The entire batch of air-
4-4
entraining admixture shall be discharged prior to the completion of the water discharge cycle.
E. Scales. The scales for weighing aggregates and cement may be of either the beam type or the springless-dial type. They shall be accurate at all loads within the specifications previously stated. A sufficient number of standard fifty (SO) pound weights for calibrating and testing scales shall be furnished by the Contractor for each and testing scales shall be furnished by the Contractor for each plant. All exposed fulcrums, devices and similar working parts of scales shall be kept clean. When beam-type scales are used, provisions shall be made for indicating to the operator that the required load in the weighing hopper is being approached; the device shall indicate at least the last two hundred (200) pounds of load. The weighing equipment shall be arrange so that when operating the bin gates, the operator stands in such a position that the weighing beam or dial is in full view and he can conveniently shovel material from the weighing hopper. A port or other opening for removing an overload of any one of the several materials from the weighing hopper. A port or other opening for removing an overload of any one of the several materials from the weighing hopper shall be provided. There shall be enough clearance at the top to the weighing hopper to permit the scale operator to shovel material out of the weighing hopper. Weighing hoppers shall be constructed so as to eliminate accumulations of tare materials and to discharge fully.
On beam-type scales, at least that part of the total load which is a fraction of 100 pounds shall be indicted on a graduated beam.
Scales shall be protected from air currents that may affect the accuracy of weighing. The scales shall be kept level and in adjustment at all times . Scales for weighing bulk cement in a closed compartment shall be equipped with an independent tare beam, and the scale shall be balanced to the tare before weighing and after discharging each batch of cement. In the case of a springless-dial type of scale, the indicator shall register zero before charging the weighing hopper and after the cement is discharged.
F. Protection. Weighing, indicating, and control equipment shall be protected against exposure to dust and weather.
G. Batch Trucks . When the aggregates are delivered to the mixer in trucks, each batch shall be in a separate compartment of the capacity required by the Engineer. Suitable covers shall be provided for the batch compartments of the trucks to protect the cement from the wind. All trucks, truck bodies, bulkheads and compartments used in proportioning an transporting to the mixer of concrete materials shall be so designed and operated to insure the charging of the mixer, batch by batch, with the proper amounts of each materials without overspillage, intermixing of batches or wastage. Any units which, in the opinion of the Engineer, do not operate satisfactorily, shall be removed from the work until properly rebuilt and corrected.
4.07 Mixing Concrete. Mixing of concrete shall conform to one of the two following methods:
A. Mixer on Project. The mixing machine used shall be of an approved type known as batch mixer and of a design having a suitable device for automatically measuring the proper amount of water accurately to onehalf (~) of one (1) percent and for automatically timing each batch of concrete so that all materials will be mixed together for the minimum time required. If the timing device becomes broken or fails to operate, the Contractor will be permitted to continue for the balance of the day and for one additional day without the timing device while
4-5
the same is being repaired providing that each batch of concrete is mixed not less than two (2) minutes.
All of the materials for each batch of concrete, including the water, shall be mixed not less than one and one-half (l~) minutes after all of the materials are in the mixer, which shall revolve at the speed for which it is designed but not less than fourteen (14), or more than twenty (20) revolutions per minute. If, in the opinion of the Engineer, a thorough mixing of the concrete is not obtained during this period of time, a sufficient number of additional revolutions at the same rate shall be given to assure thorough mixing.
The inside of the mixer drum shall be kept free from hardened concrete . No materials for a batch of concrete shall be placed in the mixer until all of the previous batch has been discharged therefrom. Water shall be added at the time the materials are being run into the mixer.
B. Central-Mixed. Shrink-Mixed or Transit-Mixed Concrete . Central-mixed, shrink-mixed or transit-mixed concrete shall be mixed and transported to the site of the work in accordance with "Standard Specifications for Ready-mixed Concrete" (A.A.S.H.T.O. Designation: Ml57) with the following restrictions:
1. Cement Content. Delivery tickets shall show the batch weight per cubic yard for each load.
2. Time of Delivery. Concrete must be delivered and discharged from the truck mixer or agitator truck within a period of ninety (90) minutes after introduction of the water to the cement and aggregate or of the cement to the aggregate. Delivery tickets shall have the time clearly shown thereon, the original or a copy thereof to be furnished the Inspector on the work before the concrete is discharged.
3. Type of Delivery Equipment . Concrete shall be delivered in truck mixers or agitator trucks (trucks providing mechanical agitation by revolving drums or revolving blade in stationary drum) operated, after time required for thorough mixing of the concrete, at the speed designated by the manufacturer as agitating speed. Delivery of the central-mixed concrete shall not be made in nonagitating equipment without securing the prior written approval of the Engineer of the type of equipment to be used and method of operation.
4. Retempering of Concrete. Retempering of concrete which has partially hardened by remixing either with or without the addition of water will not be permitted.
4.08 Protection. It shall be the responsibility of the Contractor to protect from damage all freshly poured concrete regardless of the location or type of structure for a minimum period of seven (7) days or for such longer period as the Engineer may direct. Any concrete which is damaged shall be repaired to the satisfaction of the Engineer prior to acceptance of the completed work.
4.09 Testing. Test cylinders six (6) inches in diameter and twelve (12) inches in length shall be made as directed by the Engineer.

SECTION 5
PLACING AND FINISHING CONCRETE
5.01 General. The placing and finishing of concrete as described in this section, shall include all forming, placing, reinforcing, finishing and curing.
5.02 Reinforcing Steel. Reinforcing bars shall conform to the Standard Specification for Billet Steel Bars for Concrete Reinforcement (A .A.S .H.T.O. Designation: M 31), shall be "Intermediate Grade", and shall be of the sizes and shapes indicated on the plans.
Wire fabric shall conform to the Standard Specifications for Welded Steel Wire Fabric for Concrete Reinforcement (A . A.S.H.T.O. Designation: M 55 ), and the size shall be 6" by 6" by #10/#10 gage.
5.03 Structural Concrete.
A. Forming. The forms shall be tight and constructed in a workmanlike manner, and shall be of such dimensions and so constructed as to remain rigid and unyielding under the load of wet concrete. The lumber used shall be sound and free from loose knots. The form work shall be so constructed as to permit easy removal without injuring the concrete. Lumber once used in forms shall be cleaned before being used again. Before depositing concrete, the forms shall be thoroughly wetted and cooled, and the space to be occupied by the concrete cleared of shavings, sticks of wood or other debris. Use an approved type of form clamps and ties for all forms. Form ties in walls shall be cut off back of surface of wall.
Whenever concrete is to be left exposed, the forms shall be given special attention and all splinters, defects, loose knots, etc., shall be removed. Chamfer all exposed edges of concrete one (1) inch unless otherwise directed.
Unless otherwise authorized, the form lumber which is in contact with all exposed concrete surfaces shall be plywood or shall be faced with an approved type of composition board. All joints in such plywood or facing material shall be carefully matched to prevent the forming of irregularities in the concrete surface.
The term "exposed concrete surfaces" applies to above ground outside faces of structures.
Approved type metal forms may be used. Battered, bent, or twisted forms which will affect the alignment or appearance of the finished concrete shall not be used.
Openings shall be left at the bottom of the wall forms so they may be cleaned out after the forms have been washed. The time for removal of the form work shall depend on the weather conditions and shall be subject to the approval of the Engineer.
Forms for exposed surfaces shall be coated with oil before reinforcement is placed. The oil shall be a mineral base oil which will not discolor or interfere with the finish of the concrete. Surplus oil on form surfaces and any oil on reinforcement shall be removed before concrete is placed. Forms for interior surfaces and for exterior surfaces not exposed to view may be thoroughly wet with water in lieu of oiling immediately before placement of concrete, except that the freezing weather, oiling will be mandatory.
5-1
B. Placing Reinforcing Steel. Reinforcing steel delivered or stored along the site of the work shall be neatly piled on blocks or timbers in such a way as to keep it off the ground.
Before being placed, all steel shall be thoroughly cleaned of mill rust, scale and of grease or other coatings that will destroy the bond.
Reinforcement shall be carefully placed exactly as indicated on the plans. Bars shall not be bent or straightened in a manner that will injure the material.
Bars shall be accurately and rigidly secured in position by use of such approved metal clips, spacers, bar supports, or hy-chairs as may be necessary. Should it be necessary to supply extra reinforcing bars for the purpose of supporting the mat of reinforcement and tying it together, such bars shall be furnished at the expense of the Contractor.
Splices shall not be made at point of maximum stress and where made, bars shall be lapped at least forty (40) times their least diameter.
Reinforcement shall be secured in position, inspected and approved before placing of concrete.
C. Placing Structural Concrete. The Contractor shall give notice sufficiently in advance of placing concrete to permit proper inspection of forms and reinforcement by the Engineer. Concrete shall be as specified in Section 4.
After the completion of the mixing, the concrete shall be rapidly conveyed to and deposited in the forms. The concrete shall be deposited in such a manner as will prevent the separation of the ingredients and permit the most thorough compacting. It shall be compacted by spading or by a mechanical vibrator until the ingredients have settled in the proper place and the surplus water is forced to the surface. Form vibrators shall be used only with the specific approval of the Engineer.
The concrete shall be placed in such manner as to prevent excessive crawling and segregation of the aggregate.
Location of all construction joints must be as approved by the Engineer. Such joints shall be roughened, rabbeted horizontally and grouted with cement, before joining new concrete to old. Construction dowels shall be placed as directed by the Engineer in both reinforced and non-reinforced work.
Before pouring new concrete on top of concrete which has set, the surface shall be thoroughly cleaned of foreign matter and laitance of scum, drenched and slushed with neat cement.
D. Finished. All exposed formed concrete surfaces exclusive of any surfaces below the water line or below the line of backfill, and exclusive of curbs and walks, will be given the surface finish described as follows:
As soon as the concrete has set sufficiently to permit it, the surface shall be thoroughly wet with a brush and rubbed with a No. 16 carborundum stone or an abrasive of equal quality, bringing the surface to a paste. The rubbing shall be continued sufficiently to remove all form marks and projections producing a smooth, dense surface without pots or irregularities. The material which, in the above process, has been ground to a paste shall be carefully spread or brushed uniformly over the entire surface and permitted to reset. The
5 - 2
final finish shall be obtained by thoroughly rubbing with a No. 30 carborundum stone or an abrasive of equal quality. This rubbing shall continue until the entire surface is of a smooth texture and uniform in color.
5 . 04 Curb and Gutter, Curbwalk, Sidewalks, Driveways and Cross Pans.
A. Preparation of Subgrade. All subgrade upon which concrete is to be placed shall be thoroughly compacted and moistened . Concrete shall be placed only when the subgrade is moist and not when it is too wet or dry.
B. Forms. Metal or wooden forms may be used. They shall be free from warp, of sufficient strength to resist springing out of shape. Forms shall be cleaned of all mortar and dirt and oiled before they are used . They shall be set to the established line and grade, being well staked, braced, or otherwise held in place . Forms shall remain in place at least twelve (12) hours after concrete has been placed against them or for a longer period if so directed by the Engineer.
Maximum deviation of the top surface shall not exceed one-eighth ( 1/a ) inch in ten (10) feet or the inside face not more than one-quarter (~) inch in ten (10) feet . The method of connections between sections shall be such that the joint thus formed is tight and free from movement in any direction. Approved flexible forms shall be used for construction where the radius is one hundred fifty (150) feet or less.
C . Placing Concrete. After the inspector has approved the forms and subgrade, then concrete shall be deposited on the subgrade to the required depth and width in successive batches and in a continuous operation. The concrete shall be placed as uniformly as possible to minimize the amount of spreading necessary. While being placed, the concrete shall be spaded and/or vibrated with suitable tools to prevent the formation of voids or honeycomb .
Wire fabric shall be placed at a point three (3) inches below the surface of a cross pan and squared-out return . The fabric shall be fully supported on precast mortar blocks prior to placing the concrete.
1. Expansion Joints. Expansion joints shall be provided in accordance with the thickness and other dimensions indicated on the plans or as directed by the Engineer. The joint filler shall extend the full depth and width of the concrete and shall be set vertical with the tip edge flush with the finish surface of the concrete. Preformed expansion joint filler conforming to the requirements of A.A.S.H . T.O. Specification M 213-74 or latest revision shall be used.
Expansion joints shall be provided at the following locations and shall be in place prior to the placing of concrete:
a. Between back of sidewalk and driveway slab or service walk.
b. Between new concrete and existing masonry buildings. c . As shown on the plans. d. As directed by the Engineer.
D. Finishing. Finishing shall be done with a screed or mule designed to give proper shape to the section as detailed. Final finish shall be applied by a float or other means approved by the Engineer. The final texture desired may be obtained by lightly brooming the surface, edge
5-3
to edge, to produce a slightly roughened finish at the discretion of the Engineer. Particular care shall be used to finish gutter flow line to a true uniform grade. Any pockets which will pond any appreciable amounts of water shall be removed by grinding . No water shall be added to the concrete surface to facilitate finishing.
1. Edging. Before final finishing is completed and before the concrete has taken its initial set, all edges in contact with the forms shall be tooled with an edger having three-eighth (3/0 ) inch radius.
2 . Jointing. Transverse joints shall be placed at maximum intervals of ten (10) feet. To control random cracking, the joints shall be formed, sawed or tooled to a minimum depth of one-quarter (~) of the total thickness. If divider plates are used, the maximum depth of plates shall not be greater than one-half (~) the total thickness. The joints shall be finished with a jointer having a width no greater than five-sixteenth (s/16) inch and a depth of not less than three-quarter (~) inch. A maximum joint width at the finished surface shall be no greater than five-sixteenth (s/16 ) inch.
Tool joints shall be spaced as follows:
a. Not more than ten (10) feet nor less than five (5) feet apart in curb and gutter and curbwalk.
b. Not more than six (6) feet nor less than four (4) feet apart in sidewalk.
c. In driveways one or two joints equally spaced as applicable .
d. As directed by the Engineer.
3. Marking. All sidewalks, curb, gutters and driveways shall have the name of the Contractor and the year of construction impressed therein, using block letters one (1) inch high and three-eighth (3/ 0) inch deep. One impression shall be made in each driveway. Impressions shall be made in sidewalks, curbs, gutters at each end of the construction, or at one hundred (100) foot intervals and at each extension to curbing.
5.05 Curing. Concrete shall be cured by protecting it against moisture loss, rapid temperature change, from rain, flowing water and mechanical injury for a period of not less than five (5) days after placement.
It shall be the Contractor's responsibility to protect from the elements and traffic, and if neglected the Engineer shall direct that the necessary protective measures be taken at the expense of the Contractor, and no further pouring will be permitted.
A. Moist Curing. Moist curing shall be accompli s hed after initial set by covering with wet burlap, cotton mats, or other approved fabric used singly or in combination. Curing mats shall be kept continuously wet and in intimate contact with the concrete for the duration of the mo ist cure.
B. Waterproof Paper and Polyethylene Sheets. The surface of the concrete shall be thoroughly moistened with a fine spray of water and then covered after initial set with the waterproof paper or sheeting. Paper or sheeting shall cover the entire width and edges shall be lapped at least twelve (12 ) inches to insure complete cov erage. Paper or sheeting shall be adequately weighted to prevent displacement or billowing due to wind. (•sheet Materials for Curing Concrete", A.A.S.H.T.O. Des ignation: M 171-70.)
5 -4
C. Liquid Membrane Curing Compound. Only white pigmented membrane curing compound shall be used (PROTEX Promulsion 50AW or equivalent ) and shall be applied immediately after the water sheen has left the finished concrete. The compound shall be applied at a rate of one gallon per 200 square feet .
5.06 Cold Weather Concreting. Except by specific written authorization, concreting shall cease when descending air temperature in the shade and away from artificial heat falls below 40 degrees Fahrenheit. It shall not be resumed until the ascending air temperature in the shade and away from artificial heat rises to 35 degrees Fahrenheit.
When concrete is permitted during cold weather, the temperature of the mix shall be not less than 60 degrees Fahrenheit or more than 80 degrees Fahrenheit at the time of placing. Aggregates or water or both may be heated, but the water shall not be hotter than 175 degrees Fahrenheit and aggregates shall not be used which are hotter than 150 degrees Fahrenheit. Before concreting is started, remove ice, snow and frost.
When concrete is being placed in cold weather and temperature may be expected to drop below 35 degrees Fahrenheit, a supply of straw, insulated curing blankets, or other suitable material shall be provided along the line of work.
At any time when the air temperature may be expected to reach the freezing point during the day or night, the materials so provided shall be spread over the concrete to a sufficient depth to prevent freezing of the concrete . Concrete shall be protected from freezing temperatures until it is at least five (5) days old. Concrete injured by frost action shall be removed and replaced at the Contractor's expense.
5.07 Hot Weather Concreting. Except by written authorization, concrete placing shall cease if the temperature of the plastic concrete cannot be maintained at 90 degrees or lower. To facilitate the placement of concrete in hot weather, the aggregates or water or both may be cooled.
5.08 Opening to Traffic. Concrete shall not be opened to traffic for a period of at least seven (7) days after the last concrete has been placed or for a longer period of time if the Engineer considers it necessary. It shall be the obligation of the Contractor to maintain suitable barricades for this purpose.
5.09 Measurement and Payment.
A. Payment of structural concrete shall be included in the contract unit price of the applicable item such as "Construct Catch Basin Inlet", etc.
B. Measurement and payment for concrete items shall be made on the following basis:
Vertical curb and gutter Per lineal Curbwalk Per lineal 8" Concrete alley paving Per square Concrete sidewalks and driveways Per square Cross pans Per square Handicap Ramps (Sec. 2 .19) Per each
