1.11.7 If people or vehicles could be in the vicinity of the excavation after dark,
warning lights shall be used to mark the limits of the work. If possible, the
grade should slope away from the excavation.
1.12.1 Excavation work on or near roads, streets and sidewalks shall meet the
requirements of GI 1021.000 and shall not be performed without prior approval of the relevant authorities.
1.12.2 Saudi Arabian Government approval shall be obtained through SA
Government Affairs prior to excavation work on, under (e.g., thrust
boring), or near a public highway, railway or utility right-of-way (see
Chapter II-11, Roadworks ).
1.12.3 Trenches in roads and streets shall be completely covered with properly
designed steel plates where traffic flow needs to be maintained over the
trench. Such trenches shall be properly shored to prevent cave-in (see
Section 1.7). The trench cover plate thickness shall be selected based on
the width of the trench, grade of steel and weight of heaviest expected
traffic (e.g., fire truck, fully loaded tractor-trailer truck). See Figures 1.17
to 1.20 for typical cover plates for road trenches. Figure 1.21 shows typical
sidewalk protection.
1.13.1 A documented inspection shall be performed by an excavation competent
person before workers are allowed to initially enter an excavation or after a
change in site conditions (e.g., rain storm, groundwater infiltration,
sidewall deterioration, adjacent ground fissuring). For excavations greater
than 2.4 m (8 ft) deep, a documented inspection by the excavation
competent person shall be performed each morning before workers shall be
allowed to enter the excavation.
1.13.2 An excavation safety checklist shall be used to document these initial/daily
inspections (see Appendix B for a sample excavation inspection checklist
that shall be completed and signed each day by the excavation competent
person). If there is an unsafe condition, workers shall not be allowed to
enter the excavation.
1.13.3 Appendix B also contains a sample excavation safety pocket card that is to
be used by others at any other time (e.g., work permit issuers/receivers, SA
and contractor employees who work in or near excavations, Project
Management and proponent personnel). These excavation safety pocket
cards are available from the area Loss Prevention office.
Backfilling and removal of shoring shall be accomplished first by backfilling up to a
level allowing for the removal of the lower braces. Another layer of backfill shall be
