shall be accounted for in the precast unit design.
A. Precast Concrete Unit Design
1. Design standard precast concrete units to withstand design load conditions in
accordance with ACI 350. Design must also consider stresses induced during

handling damage. Design loads for precast concrete units shall be indicated on
the shop drawings and designed by a licensed professional engineer.
2. The structural design shall take into account discontinuities in the structure
produced by openings.
3. The Precast Pump Station with Integral Valve vault shall be designed to support

3) Exterior Walls
a) All exterior walls below finished grade shall be designed
for an equivalent fluid pressure of 90.0 psf minimum
caused by saturated earth pressure. The top of the
pressure diagram is assumed to originate at finished
grade. In addition to the soil pressure, a Live Load Traffic
Surcharge shall be applied according to the AASHTO
Specification.
4. The structures shall be designed to prevent floatation without the benefit of skin
friction and the weight of mechanical equipment when the ground water level is at
finished ground surface. The factor of safety against uplift calculated as a ratio of
the total resistance force (excluding skin friction and the weight of the equipment)
to the total hydrostatic uplift force shall be at least 1.15. The net uplift force shall
be transferred to the anti-buoyancy collar.
B. Joints and Sealants
1. Joints and sealants between adjacent units shall be of the type and configuration
indicated on the shop drawings meeting specified design and performance
requirements.
