Lock Block Retaining Wall
1) This item remains to be addressed. While the geotechnical engineer and I had a
telephone conversation about the approach, a formal written response is
required to be provided.
Retaining walls are required to be designed considering a safety factor of 1.5 against
sliding and overturning. The current design provides a factor of safety of 1.1 against
sliding and 1.3 against overturning. The design of the Lock Block Retaining wall
should be revised utilizing the required safety factors. IBC 1806.1
S2.2 Main Floor Framing Plan
14) Provide detailing for the connection of the S/HD15B holdowns to the WF beams
below. Provide calculations to justify the design.
Reference grid N. The SW3 shear walls and associated holdowns from above are
supported by the framing at the Main Floor level. The calculated holdowns are shown
along the grid Q shear line in lieu of the grid N shear line. Provide an analysis for
framing along grid N that supports the shear walls and overturning holdowns from
above.
