same working area;
 Collision with plantor vehicles and
live traffic;
 Workers struck by plant, very high
risk of fatality;
 Uncontrolled rig movements;
i. Worker pedestrian routes to be designed and implemented with clear
signage to provide segregation;
ii. Instruction to workers at induction on access routes around the project;

sheetpiling rig
 Working in proximity
to existing structures
and services;
 Underground
services;
 Collision with overhead services;
 Damaging underground services
with weightof rig;
 Blocking access routes;
 Rig striking moving and/or stationary
structures;

i. Ensure sheetpiling rig is setup correctly, is on firm level ground as per rig
plan;
ii. Underground services such as buried electrical cable trays determined
and clearly communicated;
iii. Solid barriers should be situated,where practicable,to protect rig from
traffic routes around working radius ofcab;
iv. Consideration given to overhead services and existing structures when
siting rig;
