* Optional shoring methods have been removed and
clarified in the plans. As Depicted in the plans the
East Side will use trench box shoring and the North
Side will use site built shoring per stamped
structural drawings.
*Utilities are now depicted on the excavationstabilization plan.
*Neighbor approval letter was included on the
cover sheet of the plans and is now also
added to the excavation stabilization plan.
*North Side Shoring detail will be used fornorth side stabilization andstamped engineering docs are includedwith the drawings.
* Excavation stabilization plan has beenclarified and has been reviewed and approvedby our structural engineer. See new drawingsand stamped shoring details.

File Name: 134 MAPLE_BLDG PERMIT DRAWINGS.pdf Per OSHA standards vertical
cuts cannot exceed 5' in depth. If
6' is needed the soil must be laid
back at 1.5:1 sloe or a shoring
system must be provided.

File Name: 134 MAPLE_BLDG PERMIT DRAWINGS.pdf Without a soils report, it is
assumed the site has type C
soils. Type C soils require a
minimum 1.5:1 layback. Please
refer to OSHA Regulations
(Standards - 29 CFR). Sloping
and Benching - 1926 Subpart P

If 1.5:1 layback is not
achievable, a shoring system
must be utilized. The 4' and 5'
bench do not meet the OSHA
standard.

be utilized.
* Lay back will not be necessary with
updated shoring system.
* Type C soils will be assumed. Trench box shoringmethod will be used on the East Side of the excavation. Bench cut will not be needed.
* Excavation Stabilization (EX 1) plan has been
updated and now EX 2.0 has the stamped
drawings from our structural engineer.
* Plan has been updated to visually show where
each shoring method will be used.
