1.3.3 Adequate and suitable protective systems (i.e., benching, sloping or
shoring) shall be planned for if the excavation will be at a depth of 1.2 m (4
ft) or more in soil other than stable rock, as per Section 1.7. Excavations
less than 1.2 m (4 ft) deep may also require protective systems if sidewall
cave-in hazards exist.
1.3.4 An excavation plan shall be prepared as follows:
A. For excavations greater than 2.4 m (8 ft) deep in Type B or C soil, an
excavation plan (e.g., shoring design calculations and drawings) that meets
the requirements of this chapter shall be developed by a degreed
civil/structural engineer. See Table 1.1.
B. For excavations greater than 6 m (20 ft) deep, regardless of soil type, an
excavation plan (e.g., shoring design calculations and drawings) that meets
the requirements of this chapter shall be developed by a degreed
civil/structural engineer and reviewed by the SA Consulting Services
Department (CSD).
C. If an excavation plan is required and shoring is used, the plan shall:
• Describe the materials and shoring system to be used.
• Indicate whether or not any shoring components will remain after
filling or backfilling.
• Provide plans, sketches and/or details along with calculations.
• Indicate the sequence and method of shoring installation and removal.
1.4.1 SA work permit(s) per GI 2.100 shall be obtained as required before
excavation work is started.
1.4.2 The work permit issuer shall ensure that underground utilities/installations
have been located and marked (e.g., by flags or chalk) before excavation
activities begin.
1.4.3 For grassroots projects, the contractor shall develop and implement its own
work permit procedures until such time as the SA work permit system goes
into effect. These work permit procedures shall incorporate the excavation
safety provisions and checklists from this chapter.
1.4.4 For other work sites not covered by the SA work permit system (e.g.,
nonrestricted areas), the SA proponent organization (SAPO) shall develop
and implement excavation safety procedures in accordance with this
chapter. Development of these excavation procedures shall include
participation by Utilities, Communications, Power Operations Department
(POD), Pipelines, etc., as applicable.
1.4.5 A properly completed Confined Space Entry Permit shall be obtained to
enter excavations equal to or greater than 1.2 m (4 ft) deep.
