a) Four thousand (4,000) pounds minimum compressive strength per square inch at twenty-eight (28) days for all piers, reinforced walls, floors, slabs, and other special sections where specifically shown on the plans or Standard Details.

b) Two thousand five hundred (2,500) pounds minimum compressive strength per square inch at twenty-eight

(28) days for all blocking, reinforced footings, for retaining walls not subject to hydrostatic pressure, or where specifically shown on the plans or shown in the Standard Details.

1.6 Concrete Proportioning

1.6.1 Concrete aggregate shall be proportioned by weight. When the sources of supply shall have been determined by the Contractor and approved by the Engineer, the mix shall be set by an approved testing laboratory. Mix shall be designed for a "slump" suitable for the character of structure in which the concrete is to be incorporated. All concrete shall be as specified above in paragraph 1.5.1.

1.6.2 After a suitable designed mix has been approved by

the Engineer, it shall not be changed so long as materials of the same characteristics are used in the mix. Within the limits of the various cement factors shown above, the mix shall be varied until the homogenous workable mixture, suitable for the class of structure intended, has been obtained.

1.Concrete Mixing

1.7.1 Concrete mixing shall be by means of a modern batch mixer equipped with an accurately operating water measuring device and an automatic time locking device.

1.7.2 Where a central batching plant is not operated, each mixer must have available an approved portable weighing device for use in proportioning. Each batch shall be mixed for one and one-half (1«) minutes after charging has been completed, and during such mixing period, that drum shall operate with a peripheral speed of not less than one-hundred and fifty-three (153), nor more than two-hundred and twenty-five (225) feet per minute. The number of revolutions per minute shall be between fourteen (14) and twenty (20). Retempering concrete or use of concrete in which initial set has taken place will not be allowed. Transit mixed concrete from an approved batching plant and suitable truck mixer may be approved by the Engineer.

1.8 Forms

1.8.1 Forms for concrete work may be of dressed lumber, plywood, metal or a combination thereof as may be approved by the Engineer. Where dressed lumber is used, the boards shall be surfaced both sides with tongue and groove edges, and for forms exceeding four feet (4') in height, the thickness of individual boards shall not be less than one and one-quarter (1¬) inches dressed. Forms shall be constructed mortar tight and with sufficient supports, walls and bracing to hold the concrete in line and shape without bulging.

1.8.2 Forms shall be held together by form ties so arranged as to permit the ends of the bolts to be removed to a depth of at least one and one-half (1«) inches beneath the surface of the concrete. The cavity, so formed, shall be filled as soon as possible with cement mortar proportioned so as to blend in with color and bond to the remaining portion of the wall.

On thin walls not subject to hydrostatic pressure, wiring of forms will be permitted.

1.8.3 Forms for walls, basins, flumes or other exposed structures having straight outlines, shall be erected and set so as to be true in alignment and braced sufficiently to remain in that condition throughout pouring of concrete. Corners and edges shall finish true and plumb, and curved surfaces and edges shall finish true to radius. Concrete of the highest grade and form, only, will be acceptable.

1.8.4 Where forms are to be reused, they shall be cleaned

thoroughly after dismantling, coated with form release agent and stored to prevent warping and twisting.

1.9 Reinforcing Steel

1.9.1 All steel for reinforcement bars shall be billet steel, open hearth of intermediate grade, having a tensile strength of not less than seventy thousand (60,000) pounds per square inch. For bars under three-fourths inch (3/4") in diameter, the bend test requirements shall be that the bar shall be bent cold one hundred and eighty (180) degrees around a pin having a diameter three (3) times that of the bar under test, without evidence of breaking. For bars three-fourth inch (3/4") in diameter and over, the bend test requirements shall be that the bar shall be bent cold ninety degrees (90ø) around a pin having a diameter three (3) times the diameter of the bar under test without evidence of cracking.

1.9.2 Bars shall conform in every respect to ASTM Specification A615 latest revision, for billet steel reinforcements, intermediate grade.

1.9.3 Deformed bars must be used. Bars deformed by cold twisting or bars from rerolled stock will not be acceptable, except by special permission of the Engineer. The Contractor's Bid shall be based on reinforcement steel as specified, not on steel from rerolled stock.

1.9.4 Reinforcement steel bars must be kept in racks off the ground and classified by numbers until used. Bars must be wirebrushed clean of mill scales, dirt, etc., before being placed in the forms. Where the epoxy coating is damaged, steel shall be rejected.

1.9.5 Bars for girders may be made up in unit frames. All bars shall be of sufficient length to extend through the full length of slabs and girders, and all joints shall be made over supports and by lapping for a length of at least forty

(40) diameters. No welding of bars will be permitted.

1.9.6 The brand of manufacturer shall be legibly rolled on all bars, and when loaded for mill shipment, all bars shall be properly separated and tagged with manufacturer's test identification number.

1.9.7 All steel bars shall be epoxy coated unless otherwise noted.

2. Special Provision for Spiral Welded or Smooth Wall Pipe Encasements

2.1 Casing pipe shall be smooth walled or spiral welded new prime steel conforming to the requirements of ASTM A-139. Size and wall thickness of smooth wall or spiral welded encasement pipe for boring and jacking, unless otherwise specified, is shown on Table I.5.

TABLE I.5

Pipe Sizes (O.D.) Wall Thickness

3. Embedment Materials

3.1 Classification

3.1.1 Embedment materials listed here include a number of

processed materials plus the soil types defined according to the Unified Soil Classification System (USCS) in ASTM D2487.

These materials are grouped into five (5) broad categories according to their suitability for this application.

3.1.2 Class I: Angular, one-quarter inch (¬") to one and one-half inch (1«") (6 to 40 mm) graded stone, including a number of fill materials that have regional significance such as coral, slag, cinders, crushed shells and crushed stone. (Note: The size range and resulting high void ratio of Class I material makes it suitable for use to dewater trenches during pipe installation. This permeable characteristic dictates that its use be limited to locations where pipe support will not be lost by migration of fine grained natural material from the trench walls and bottom or migration of other embedment materials into the Class I material. When such migration is possible, the material's minimum size range should be reduced to finer than one-quarter inch (¬") (6 mm) and the gradation properly designed to limit the size of the voids. An alternative to modifying the gradation is to use a geotextile fabric as a barrier to migration to fines.)

3.1.3 Class II: Coarse sands and gravels with maximum particle size of one and one-half inches (1«") (40 mm), including variously graded sands and gravels containing small percentages of fines, generally granular and non-cohesive, either wet or dry. Soil Types GW, GP, SW and SP are included in this class. (Note: Sands and gravels which are clean or borderline between clean and with fines should be included.

Coarse-grained soils with less than twelve percent (12%), but more than five percent (5%) fines are neglected in ASTM D2487 and the USCS, but should be included. The gradation of Class II material influences its density and pipe support strength when loosely placed. The gradation of Class II material may be critical to the pipe support and stability of the foundation and embedment, if the material is imported and is not native to the trench excavation. A gradation other than well graded, such as uniformly graded or gap graded, may permit loss of support by migration into void spaces of a finer grained natural material from the trench wall and bottom. An alternative to modifying the gradation is to use a geotextile fabric as a barrier to migration of fines.)

3.1.4 Class III: Fine sand and clayey (clay filled) gravels, including fine sands, sand-clay mixtures and gravel-clay mixtures. Soil Types GM, GC, SM and SC are included in this class.

3.1.5 Class IV: Silt, silty clays and clays, including inorganic clays and silts of medium to high plasticity and liquid limits. Soil Types MH, ML, CH and CL are included in this class. (Note: Caution shall be used in the design and selection of the degree and method of compaction for Class IV soils because of the difficulty in properly controlling the moisture content under field conditions. Some Class IV soils with medium to high plasticity and with liquid limits greater than fifty percent (50%) (CH, MH, CH-MH) exhibit reduced strength when wet and should only be used for bedding, haunching and initial backfill in arid locations where the pipe embedment will not be saturated by groundwater, rainfall or exfiltration from the pipe. Class IV soils with low to medium plasticity and with liquid limits lower than fifty percent (50%) (CL, ML, CL-ML) also require careful consideration in design and installation to control moisture content, but need not be restricted in use to arid locations.)

3.1.6 Class V: This class includes the organic soils OL, OH and PT as well as soils containing frozen earth, debris, rocks larger than one and one-half inches (1«") (40 mm) in diameter and other foreign materials. These materials shall not be used for bedding, haunching or initial backfill.

4. Roadway Materials

4.1 Limerock for Roadway Base

4.1.1 The limerock base course material shall conform to the

Florida Department of Transportation Standard Specifications for Road and Bridge Construction , latest edition, Section 911, Miami Oolitic Formation.

4.2 Prime Coat

4.2.1 The material used for prime coat shall be cut-back asphalt, meeting the requirements of Section 300 of the Florida Department of Transportation Standard Specifications for Road and Bridge Construction, latest edition, and all supplements thereto. The cover material for the prime coat shall be either sand (either bare or hot-asphalt coated) or screenings at the Contractor's option. The sand shall be nonplastic and free from any appreciable amount of silt, clay balls and root articles and from any noticeable sticks, trash, vegetation or other organic matter.

4.3 Tack Coat

4.3.1 The tack coat shall be Emulsified Asphalt, meeting the

requirements of Section 300 of the Florida Department of Transportation Standard Specifications for Road and Bridge Construction, latest edition, and all supplements thereto.

4.4 Asphaltic Concrete Type S-I or Type II

4.4.1 Except when otherwise directed by the Transportation Services Division hot bituminous mixtures shall conform with Sections 330, 331, or 332 for Type S-1 or Type II Asphaltic Concrete Surface Course of the Florida Department of Transportation Standard Specifications for Road and Bridge Construction, latest edition. The Contractor shall furnish sufficient proof that the named source of material supply to be used meets Florida Department of Transportation Road Specifications. The Engineer may require additional tests from time to time and the Contractor shall furnish all material necessary for said tests.

PART (6) - TECHNICAL SPECIFICATIONS - RESTORATION

1. Excess Material

All excavated material in excess of the quantity required for backfill in the Right-of-Way, shall be removed by Contractor at Contractor's cost to a site designated by the Owner. All unusable material shall be disposed of at the Contractor's expense unless otherwise noted in these Contract Documents.

2. Work in Right-of-Way Contractors performing work within the public Right-of-Way shall be responsible to protect, during construction, all existing vegetation and facilities not authorized to be removed. Contractor shall be responsible for acquiring all state and local right-of-way permits. Contractor shall be responsible to restore all vegetation or facilities damaged during construction.

3. Tree Cutting The indiscriminate cutting of trees or disfiguring of any feature of scenic value shall not be permitted. This includes methods such as the use of herbicides. The necessary trimming or cutting of trees by Contractor in the interest of public safety or continuity of facility service shall not be considered indiscriminate where such facilities cannot bypass the obstruction without violating the minimum clearance requirements.

4. Sidewalk/Driveway Replacement

4.1 Materials

Sidewalk/driveway repairs shall be done using materials matching those disturbed during construction. Rock, asphalt, concrete, etc. shall be as specified in Exhibit I, Part (4) of the contract documents.

4.1.1 Grassing

Grassing, mulching, and watering operations when required are to begin within three (3) weeks after completion of construction or as otherwise directed and shall be continually watered until growth is initiated or until sufficient local shower activity will ensure growth. All requirements regarding grassing, mulching and watering shall be in accordance with the Florida Department of Transportation Standard Specifications for Road and Bridge Construction , latest revision or as otherwise stipulated.

Any yards or parts or right-of-way in front of private property that contain a grass mat shall be resodded with similar type sod.

4.1.2 Concrete sidewalks/bikeways shall be a minimum of four

inches (4") thick, except that alley intersections and driveways shall be six inches (6") thick. All concrete sidewalk/bikeway work shall be in conformance with Section 522 (Concrete Sidewalks), of the Florida Department of Transportation Standard Specifications for Road and Bridge Construction , latest edition.

5. Pavement Cutting and Replacement

5.1 Road Pavement Cutting - Open Cuts

5.1.1 Unless otherwise noted on the drawings, and/or in accordance with the right-of-way permit, open cutting of existing pavement will generally not be allowed, but may be considered under one or more of the following conditions:

a) Subsurface obstructions including rock;

b) Extreme high water table;

c) Limited space for jack and bore pits;

d) Condition of roadway surface - including imminent resurfacing and rebuilding, provided inspection and approval beforehand is made by the City;

e) Extreme economic hardship is proven with adequate supportive data.

5.1.2 Where an open cut has been permitted, replacement of

backfill, base and wearing surface shall be in accordance with the Standard Details (for both paved and unpaved roads) and/or special stipulations of the right-of-way permit.

5.1.3 Limerock from a Florida Department of Transportation

approved pit shall be on the job site during open cutting. When the specified compacted limerock base is greater than six inches (6"), the base shall be constructed in two (2) or more lifts.

5.2 Temporary Restoration

5.2.1 If the restoration is incomplete at the end of the day, the trench shall be backfilled and made flush with existing pavement edges. Temporary asphaltic patches are permitted when restoration of the road is incomplete. When using a temporary patch, the cut shall be properly back-filled, with compaction meeting the density requirements specified, primed, then the cold or hot mix asphaltic patch applied. At such time when the conditions are corrected, the temporary cold or hot mix asphaltic patch used shall then be removed and the final asphaltic overlay shall be evenly applied, as required. The temporary patch may be utilized for a period from the commencement of the open cut, not to exceed ninety (90) days for each cut.

5.2.2 Upon backfill and completion of the base, if the hot mix asphalt is not immediately placed and when authorized, a temporary cold or hot mix asphaltic patch with a smooth all-weather surface may be utilized.

5.2.3 Before a lane is open to traffic, an asphaltic patch must be provided where applicable.

5.3 Conditions of Open Cuts (if permitted)

5.3.1 On dead-end streets, collector streets, and high traffic streets, trenching and pipe laying shall be performed in such a manner that at least one-way traffic is maintained at all times.

5.3.2 All trench lines across existing pavements, driveways, sidewalks, curbs, etc., shall be saw cut in straight parallel lines.

5.3.3 Contractor shall exercise care to minimize amount of

pavement, sidewalk, driveways, and curbing to be removed.

The final decision as to the amount of removal allowed shall rest with the Engineer.

5.3.4 Pavement shall not be left unrepaired overnight. If

Contractor wishes to repave all damaged areas at one time, and such request is approved by Engineer, a cold patch mix shall be utilized immediately until final pavement restoration.

6. Paving

6.1 Limitation of Operations

6.1.1 Asphaltic Concrete shall be placed in accordance with FDOT SPEC Section 330.

6.1.2 Asphalt plant and placement operations shall not commence during periods of adverse weather. The mix shall be spread only on prepared, firm, and dry surfaces. Temperature shall be above forty degrees (40ø)F and winds shall not be of velocity to cause blowing sand, dust, etc., to deposit upon the application surface.

6.1.3 Temperature - Temperature of the mixture at time of

spreading shall be between 275øF and 350øF. All other mixture temperatures will be rejected.

6.1.4 Rain and Surface Conditions - Any mixture caught in transit by a sudden rain may be laid, but at the Contractor's risk.

Should such mixture prove unsatisfactory, it shall be removed and replaced with satisfactory mixture at the Contractor's expense. In no case shall the mixture be laid while rain is falling or when there is water on the surface to be covered.

6.2 Preparation of Surfaces

6.2.1 Prior to the laying of the mixture the edges of the area to be patched shall be saw cut in smooth, straight lines.

6.2.2 The surface of the base or pavement to be covered shall be cleaned of all loose and/or organic material. Any irregular areas shall be properly beveled or smoothed out.

6.2.3 All structures which will be in contact with the asphalt mixture shall be painted with a uniform tack coat of asphalt cement to provide a closely bonded, watertight joint.

Tack coat shall be emulsified asphalt, meeting the requirements of Section 300 of the FDOT Standard Specifications for Road & Bridge Construction , latest edition and all supplements thereto.

6.2.4 A tack coat shall be required on the following surfaces:

a) Between successive surface courses;

b) Between successive leveling courses;

c) Between the leveling and surface courses; and

d) On old pavements to be patched or leveled.

A tack coat on freshly primed surfaces or surface treatment will be required only when so directed by the Engineer.

6.3 Placing Asphalt

6.3.1 Asphalt patches shall be filled by hand or by mechanical means. In either case, rolling shall immediately follow.

When using mechanical spreaders for overlays or strip patches, the following paragraphs (6.3.1.1 through 6.3.1.6) shall be adhered to.

6.3.1.1 All asphaltic concrete mixtures (including leveling courses), other than those adjacent to curb and gutter or other true edges, shall be laid with the use of string lines to assure an accurate, uniform alignment of the pavement edge.

6.3.1.2 Depth of each layer shall be checked at frequent intervals, not to exceed twenty five feet (25'). Any deviation from the required thickness, in excess of the allowable tolerance, shall be immediately corrected.

6.3.1.3 No layer shall be greater than two inches (2") when

compacted. Where a surface course is constructed to a thickness greater than two inches (2"), it shall be constructed in approximately equal layers, each not exceeding two inches (2").

6.3.1.4 Laying Width: Where necessitated by traffic conditions, mixture shall be laid in strips in such manner as to provide for the passage of traffic. Where the road is closed to traffic, mixture may be laid to the full width, by machines traveling in parallel.

6.3.1.5 Spreading Finishing: Upon arrival, mixture shall be dumped into the approved mechanical spreader and immediately spread and struck-off to the full width required and to such loose depth for each course that, when the work is completed, the required weight of mixture per square yard, or the specified thickness, will be secured. An excess amount of mixture shall be carried ahead of the screed at all times. Hand raking shall be done behind the spreader as necessary.

6.3.1.6 Correcting Defects: Before any rolling is started, the surface shall be checked, any irregularities adjusted, and all drippings, fat sandy accumulations from the screed, and fat spots from any source shall be removed and replaced with satisfactory material. No skin patching shall be done.

When a depression is to be corrected while the mixture is hot, the surface shall be well scarified before the addition of fresh mixture.

6.4 Compaction

6.4.1 Compaction on small patches shall be accomplished through the use of five-ton rollers, first rolling the edges of the patch, then following with the center of the patch to prevent upheaval or separation at the joints. Do not overroll.

6.4.2 When compacting overlays or longitudinal patches, the

following equipment and sequences shall be used for each spreader in operation. Contractor shall furnish a separate set of rollers with their operators. Rolling shall be done in the following sequence, with the equipment as noted, unless otherwise permitted by the Engineer.

6.4.2.1 Seal rolling, using tandem steel rollers weighing six and one half (6.5) to seventeen (17) tons, following as close behind the spreaders as is possible without pick-up, undue displacement or blistering of the material. On hot days, and where the asphalt material is too hot to roll without damage, some delay may be necessary.

6.4.2.2 Rolling with self-propelled pneumatic-tire rollers, following as close behind the seal rolling as the mix will permit.

Roller shall cover every portion of the surface with at least five (5) passes.

6.4.2.3 Final rolling with the six and one half (6.5) to seventeen

(17) ton tandem steel roller, to be done after the seal rolling and pneumatic-tire rolling have been completed, but before the pavement temperature has dropped below 140øF.

6.4.2.4 Contractor shall take note not to overroll pavement .

6.4.3 Compaction of Crossovers: When a separate paving machine is being used to pave pipe crossovers, compaction of the crossovers may be done by one eight (8) to ten (10) ton tandem steel roller. If crossover, intersections with acceleration and deceleration lanes are placed with the main run of paving, a traffic roller shall also be used in the compaction of these areas.

6.4.4 Rolling Procedures

6.4.4.1 Rolling shall be longitudinal. Where the lane being placed is adjacent to a previously placed lane, center joint shall be pinched or rolled, prior to the rolling of the rest of the lane.

6.4.4.2 After the rolling or pinching of the center joint, rolling shall continue across the mat by overlapping each previous roller path by at least one-half the width of the roller wheel. The motion of the roller shall be slow enough to avoid displacement of the mixture, and any displacement shall be corrected at once by the use of rakes, and the addition of fresh mixture, if required. Final rolling shall be continued until all roller marks are eliminated.

6.4.5 Compaction of Areas Inaccessible to Rollers: Areas which are inaccessible to a roller (such as areas adjacent to curbs, headers, gutters, bridges, manholes, etc.) shall be compacted by the use of hand tamps or other approved satisfactory means.

6.5 Protection of Finished Surface

6.5.1 Sections of newly compacted asphaltic concrete which are to be covered by additional courses shall be kept clean until the successive course is laid.

6.5.2 Upon completion of the finished pavement, no dumping of any material directly on the pavement will be permitted.

9.1 Removal of Vegetation

9.1.1 Removal and/or replacement of existing lawns and shrubbery shall be accomplished in so far as practicable in accordance with the desires of the property owner, and in all cases shall be acceptable to the Engineer. Where possible, sod lawn areas shall be removed in one foot (1') square or rolled sections, carefully preserved, and replaced on a prepared top soil base after all other construction operations are completed. Sod shall be rolled and watered as necessary to establish growth. In areas where the turf is not adequately thick to be removed as sod, the entire area that is damaged shall be replaced with a six inch (6") layer of topsoil, fertilized, raked and seeded with the same grass as is predominant in the existing lawn. The finished surface must be smooth and uniform throughout.

9.1.2 Shrubbery shall be expertly removed and shall be carefully preserved for replanting. Adequate earth ball shall be removed to guard against damage to the root system. Shrubs shall be replanted only after all other construction operations are complete. The excavation made for replanting shall be six inches (6") larger in every dimension than the ball removed with the shrub. This additional space shall be filled with a mixture of one half topsoil and one half peat moss. Care shall be taken to set the top of the ball flush with the surrounding ground surface. Any shrubbery damaged due to negligence of the Contractor shall be replaced at his expense.
