-Revisions thereof and additions thereto and

Special Provisions for Materials and Construction

Concrete:

Earth pressure calculated based on Coulomb Theory.

All structure concrete shall be Mix. No. 3 (3500 psi) except

as noted below under reinforcing steel.

Reinforcing Steel: Reinforcing steel shall conform to A 615, Grade 60. All

splices, not shown, shall be lapped as per Bar Lap Charts.

Minimum cover for any bar shall be 2’’ unless otherwise

noted, with the exception of bars at the bottom and sides of

all footings which shall have 3’’ minimum cover.

Design Parameters:

Angle of Internal Friction:

33 degrees for excellent soil

30 degrees for good and poor soils (and all walls on pile footings)

7/8/83

7-16-02

Reinforcing Steel Design: fy = 60.0 ksi.

For Wall Types E and F, passive earth pressure from top

of footing to bottom of shear key was utilized in the design.

In these cases, the top of footing shall have a minimum of

30’’ cover.

Safe bearing pressures are factored resistances.
