PROGRAM Note:
REINFORCED CONCRETE. No reinforcing steel shall be displaced to accommodate the installation of raceways and outlet boxes. In general, all embedded conduits shall be located in the physical center of the particular section of concrete. Raceways embedded in reinforced concrete shall require special clarification. Particular attention is called to the fact that there are many extenuating conditions where the Contractor may be instructed in writing during the course of the project not to place embedded conduits in certain areas, generally due to the possibility of unsightly cracking or for structural reasons. This instruction shall not entitle the Contractor to extra compensation.
REINFORCED CONCRETE. Floors. Floors shall be constructed to a 125 mm thick with 30 MPA concrete in general unless the tenant specifically required a higher loading requirement. Point floor loading and special toppings are not allowed for in the slabs. All floors will be fully reinforced as required and inspected by the engineer prior to all pours.
