§ 15.01.1160. Placing.

Concrete shall not be placed until the subgrade, forms and steel reinforcement have been inspected and approved by the city.

The concrete shall be initially placed as closely as possible to its final position in the forms and shall be worked into the corners and angles of the forms and around all reinforcement and embedded items in a manner to prevent segregation of aggregates. Unless otherwise specified, slab concrete shall be placed to the design thickness in one continuous layer. Formed concrete shall be placed in horizontal layers not more than twenty inches thick. Hoppers and chutes, pipes or concrete pumps shall be used as necessary to prevent splashing of mortar on the forms and reinforcing steel above the layer being placed.

Immediately after the concrete is placed in the forms, it shall be consolidated by spading, hand tamping or vibration as necessary to insure smooth surfaces and dense concrete. Each layer shall be consolidated to insure monolithic bond with the preceding layer. If the surface of a layer of concrete in place sets to a degree that it will not flow and merge with the succeeding layer when spaded or vibrated, the developer/contractor shall discontinue placing concrete and, shall make a construction joint in accordance with Section 15.01.1170.

If placing is discontinued when an incomplete horizontal layer is in place, the unshed end of the layer shall be formed by a vertical bulkhead at a location approved by the engineer.

No concrete flat work shall be placed or finished in the rain or snow.
