* Four Separate Slabs Formed at each Post.
Note 1: An additional layer of 6 x 6 - 10/10 WWF at mid height of new slab would be advisable in any extremely
hot or cold climate to control cracking due to temperature fluctuations and shrinkage.
At anchor bolt locations only keep WWF mesh below the elevation of the anchorage to avoid
drilling interference with the wire.
Note 2: The main reinforcing and lower temperature steel shall be Grade 60 deformed bars
Note 3: The tolerance on spacing of the bars in each direction shall be the value shown, plus or minus 1 inch.
In addition, the number of bars specified in the table must be used.
Note 4: The concrete outline dimensions and the reinforcing shown are for a foundation bed allowable bearing
capacity of not less than 2,000 lb/sq ft (1 ton per square foot). Many clays, and most all firm clay, hard clay,
sand & clay mixes, dry sands, course dry sands, dry sand and silt mixes, sand and gravel mixes, and gravel
type soils meet or exceed this allowable bearing capacity. If there is question regarding the foundation bed
allowable bearing capacity, a soils testing engineer should be consulted. Situations where the allowable bearing
capacity is lower than this value will require special attention.
