Masonry: _ All pavers or brick will be chosen by City Staff and purchased by the City of Conway _ All pavers to be installed on concrete bedding with the use of leveling sand and connected with mortar. _ All brick to installed per ICC building codes 3. Workmanship: a. Subgrade Condition _ The finished subgrade shall be maintained in a smooth, compact condition and any areas which are disturbed prior to placing of the concrete shall be restored at the contractor's expense. The subgrade shall be moist at the time the concrete is placed. Water shall be uniformly applied ahead of the pouring operations as directed by the engineer. Large boulders and other obstructions shall be removed to a minimum depth of 6-inches below the finished subgrade elevation, and the space shall be backfilled with sand, base course material or other material or suitable material which shall be thoroughly compacted by rolling or tamping. _ The subgrade shall be accurately trimmed to the required elevation with .1 tolerance. High areas shall be trimmed to proper elevation. Low areas may be filled with suitable material and compacted to the specified density or filled with concrete integrally with the placing of pavement. 4. Setting Forms: The forms shall be accurately set to line and grade and such that they rest firmly, throughout their entire length upon the compacted subgrade surface. Forms shall be joined neatly and tightly and braced to resist the pressure of the concrete and the finished operations. The alignment and grade of all forms shall be approved before and immediately prior to the placing of concrete. 5. Slip-forming: The slip-forming method will be allowed, provided that an acceptable finished product, true to line, grade, and cross section is consistently produced. 6. Mixing Concrete: Concrete shall be mixed in accordance with the requirement of Section 03000. 7. Installation: _ The concrete shall be distributed on the subgrade to such depth that, when it is consolidated and finished, the thickness required by the drawings will be obtained at all points and the surface will at no point be below the grade specified for the finished surface. The concrete shall be deposited on the subgrade in a manner which will require as little re-handling as possible. Placing of the concrete shall be continuous between transverse joints, without the use of intermediate bulkheads. _ Reinforcement shall be placed as shown on the drawings shall be maintained at this location during the placing and finishing operation. _ Concrete shall be thoroughly consolidated against and along the faces of all forms by means of vibrators. Vibrators shall not be permitted to come in contract with the sub-grade or a side form. Vibration at any one location shall not continue so long as to produce puddling or the accumulation of excessive grout on the surface. In no case shall the vibrator be operated longer than 15 seconds in any one location. 8. Striking-off, Consolidating and Finishing Concrete: Immediately after the placing, the concrete shall be struck off, consolidated and finished, to produce a finished product conforming to the existing area and or required by the drawings, specifications and instructions. 9. Straightening and Surface Corrections: _ After floating has been completed and the excess water removed, but while the concrete is still in a plastic stat, the surface of the concrete shall be tested for trueness with an accurate 10-foot straightedge. The straightedge shall be furnished by the contractor. The straightedge shall be held in successive positions parallel to the walk center line, in contact with the surface, and the whole area tested from the side of the slab to the other as necessary. The advance along the walk shall be in successive stages of not more than one-half the length of the straightedge. Any depressions shall be immediately filled with freshly mixed concrete and struck-off consolidated and refinished. High areas shall be cut down and refinished. Straightedge testing and surface correction shall continue until the entire surface appears to conform to the required grade and cross section. All surface irregularities exceeding _ inch in a 10-foot span shall be corrected. 10. Final Finish: As soon as the water sheen has disappeared and just before the concrete becomes non-plastic, all edges, including expansion joint edges, shall be finished with an edging tool having a radius of _ inch, finally the top shall be given a light broom finish perpendicular to the forms. 11. Joints _ Transverse Construction Joints: Transverse construction joints shall be constructed at the end of all pours and at other locations where the pouring, operation are stopped for as long as 30 minutes. Construction joints, however, shall not be placed within five feet of any other transvers joint or of either end of a section of walk. If sufficient concrete has not been placed to form a slab at least five feet long, the excess concrete, back to the last preceding joint, shall be removed. The joints shall be formed by placing perpendicular to the profile and center line of the walk. Construction joints shall have tooled edges with a _ inch radius. _ Transverse Contraction Joints: Transverse contraction joints shall be formed at five foot intervals and shall consist of planes of weakness created by an edging tool. The cut in the fresh concrete shall be perpendicular to the surface of the walk, shall extend to a depth of 1 _ inch below the top surface and shall have _ radius. _ Transverse Expansion Joints: _ inch expansion joints shall be formed by placing performed joint filler around all structures and at intervals not exceeding 100 feet. 12. Form Removal: After the concrete has sufficiently seat a minimum of 12-hours, the contractor shall remove the forms and shall backfill the space on each side. The earth shall be compacted and graded in a satisfactory manner without damage to the concrete work. Honeycombs shall be filled with sand cement mortar. Plastering will not be allowed on the face of the walk. Rejected walk shall be removed and replaced without additional compensation. "GeoWorks LLC".
