<br />THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br /> <br />Project No. 21-1011 November 2024 027700 -2 <br />D. Mixing Concrete: Concrete shall be mixed in accordance with the requirements of Section <br />03300. <br />3.2 INSTALLATION/APPLICATION <br />A. Placing Concrete <br />1. The concrete shall be distributed on the subgrade to such depth that, when it is <br />consolidated and finished, the thickness required by the Drawings will be obtained <br />at all points and the surface will at no point be below the grade specified for the <br />finished surface. The concrete shall be deposited on the subgrade in a manner <br />which will require as little rehandling as possible. Placing of the concrete shall be <br />continuous between transverse joints, without the use of intermediate bulkheads. <br />2. Concrete shall be thoroughly consolidated against and along the faces of all forms <br />by means of vibrators. Vibrators shall not be permitted to come in contact with the <br />subgrade or a side form. Vibration at any one location shall not continue so long <br />as to produce puddling or the accumulation of excessive grout on the surface. In <br />no case shall the vibrator be operated longer than 15 seconds in any one location. <br />B. Striking-Off, Consolidating and Finishing Concrete <br />1. Immediately after the placing, the concrete shall be struck off, consolidated and <br />finished, to produce a finished product conforming to the cross section, width and <br />surface finish required by the Drawings and Specifications. <br />2. After the concrete has sufficiently set a minimum of 12-hours, the Contractor <br />shall remove the forms and shall backfill the space on each side. The earth shall <br />be compacted and graded in a satisfactory manner without damage to the concrete <br />work. Honeycombs shall be filled with sand cement mortar. Plastering will not be <br />allowed on the face of the curb. Rejected curb shall be removed and replaced <br />without additional compensation. <br />C. Final Finish <br />1. As soon as the water sheen has disappeared and just before the concrete becomes <br />non-plastic, a light broom finish shall be given to the surface. <br />D. Joints <br />1. Transverse Construction Joints: Transverse construction joints shall be <br />constructed at the end of all pours and at other locations where the pouring <br />operation are stopped for as long as 30 minutes. Construction joints, however, <br />shall not be placed within 10 feet of any other transverse joint or of either end of a <br />section of curb. If sufficient concrete has not been placed to form a slab at least 10 <br />feet long, the excess concrete, back to the last preceding joint, shall be removed. <br />The joints shall be formed by placing a wood or metal bulkhead accurately and <br />securely in place, in a plane perpendicular to the profile and center line of the <br />pavement. Construction joints shall be sawed, in a manner similar to contraction <br />joints, so that a groove will be formed for holding the joint sealing compound. <br />2. Transverse Contraction Joints <br />a. Transverse contraction joints shall be constructed at 10-foot intervals and <br />shall consist of planes of weakness created by sawing the surface of the <br />hardened concrete. The cut shall be perpendicular to the surface of the <br />pavement and shall extend to a depth of 6 inches below the top of the curb. <br />It shall be the Contractor's responsibility to see that the sawing equipment
