1.5.1
Before excavation activities begin, the SAPO (e.g., engineering/technical)
shall confirm and mark (e.g., by flags or chalk) the location of any known
or suspected underground pipes, cables, vessels, structures, etc., that are in
the area of the proposed excavation.
1.5.2 The SAPO shall contact appropriate SA organizations, such as Utilities,
Communications, POD, Pipelines, etc., and request them to accurately
mark the locations of their underground utilities/installations.
1.5.3 The SAPO shall ensure that non-SA underground cables or utilities are also
located and marked prior to excavating. SAPO inquiries may be addressed
to Government Affairs.
1.5.4 Underground utilities and installations shall be located by reference to
drawings, discussion with the relevant organizations and by use of
cable/pipe locators.
1.5.5 Mechanical excavators shall not be used until all underground utilities and
installations have been exposed by hand digging.
1.5.6 Mechanical excavators shall not be used within 3 m (10 ft) of underground
utilities or installations. Pneumatic breakers shall only be used where
necessary to break concrete or other hard materials.
1.5.7 Excavations are not permitted under an existing foundation. Excavations
are not allowed to intersect a forty-five degree (45°) plane extending
downward from the bottom edge of an existing foundation, unless a
properly engineered support system is installed prior to start of work or the
excavation is in stable rock.
1.5.8 Existing underground piping, manholes, electrical cables, duct banks,
sidewalks, etc., that could be undermined by an excavation shall be
properly braced or shored.
1.6.1 Employees shall not work in excavations where there is pooled water, or in
excavations in which water is accumulating, unless adequate precautions
have been taken to protect employees. The necessary precautions vary with
each situation, but shall include water removal (dewatering) to control the
level of accumulating water (e.g., by pumping) and may also include
support shield or shoring systems to protect from cave-ins (see Figures 1.3,
1.6, 1.9, 1.14, etc) .
1.6.2 If water is controlled or prevented from accumulating by the use of water-
removal equipment, the water-removal equipment and operations shall be
regularly monitored to verify proper operation.
