THE CITY OF SUNNY ISLES BEACH PROJECT NO. 21-1011 BUILDING DEPARTMENT RELOCATION TO ANNEX Project No. 21-1011 November 2024 02510-2 • Material certification for polymeric stabilizing sand • Material certification for masonry sand • Concrete specifications from supplier • Manufacturer’s cut sheet for joint materials • Manufacturer’s cut sheet for dowels • Manufacturer’s cut sheet for edge restraints PART 3 EXECUTION 3.1 CONSTRUCTION METHODS The construction of the processed aggregate and concrete base material supporting the brick pavers shall be in accordance with Technical Specification 02510 for concrete sidewalks. The area of the mortar set brick pavers shall be excavated to a depth of approximately 16 inches. Where the plans specify mortar set brick, the bricks shall be installed on 8 inches of compacted processed aggregate base and 5 inches of Portland Cement Concrete installed monolithically with the adjacent sidewalk as shown in the plans and details. All mortar set bricks shall be set on a bed of mortar. All joints shall be mortared, being careful not to get mortar on exposed faces of brick. There shall be no expansion joint between the concrete sidewalks and the brick pavers. Transverse expansion joints in the concrete sidewalks shall be carried through the concrete base and the brick pavers. The transverse expansion joints shall also be carried through the brick pavers. Transverse dummy joints in the concrete sidewalk shall not be carried through the concrete base under the brick pavers. An expansion joint shall be made between the granite curb and concrete/brick face. Where the plans specify dry set brick, they shall be installed on 8 inches of compacted processed aggregate with filter fabric placed on top of the aggregate. The leveling course on top of the filter fabric shall consist of a minimum ¾ inches (maximum 1 inch) of compacted crushed stone dust. When placed, the bricks shall tightly about each other. Exposed edges of bricks shall be set on a plastic angle edge restraint. The final setting of brick shall be with a plate compactor taking care to have sufficient material to not damage the brick. After compacting with masonry sand, the area shall be flushed with water to ensure that joints have been filled. Any area that shows gaps in the joints shall be recompacted and appropriately swept, misted, or flushed. All joints shall be filled with commercial grade crushed stone dust, masonry sand, or commercial grade polymeric stabilizing sand as shown on the plans or as directed by the Engineer. If the polymeric sand manufacturer specifies a water mist for setting the joints, all the brick and adjacent areas shall be swept clear of all polymeric sand residue. END OF SECTION
