IGEM/SR/28 Edition 2
IGEM/SR/28 Edition 2 was published in May 2011 and is the result
of a review of IGE/SR/26, entitled Horizontal Directional Drilling
and Impact Moling, first published in 1999 and IGE/SR/28, entitled
Trenchless Techniques first published in 2002.
It provides requirements to those responsible for the planning
and safe operation of trenchless technology works. As such it will
assist employers comply with the duties on them with respect to
employees and other persons, including members of the public whose
safety may be affected.
The advantages of trenchless techniques are in the
ability to install new, and replace or renovate existing
underground utilities and services with minimal disturbance to the
surface or damage to other buried services, thereby reducing
above-ground activities and eliminating the need for costly and
disruptive reinstatement. These advantages open up opportunities
for installation in difficult or otherwise prohibitive expensive
locations, for example, beneath highways, access ways to plant and
other surfaced areas.
The Standard addresses health, safety and
environmental matters associated with the following trenchless
- horizontal directional drilling (HDD)
- impact moling
- auger boring and rotary drilling
- micro-tunnelling (up to 1 m diameter)
- pipe ramming and pipe jacking
- pipe splitting and pipe bursting
- refurbishment of pipes using lining techniques
- internal pipe repair system(s).
New Edition - What has Changed?
The two original Standards have been combined
and rationalised into one comprehensive Standard bringing the
subject up to date.
The Standard takes into account the implications
of environmental legislation. It will also assist in complying with
other legislation such as the Construction (Design and Management)
which have been updated since the last Standards were
Any trenchless technique needs to be planned with the objectives
of minimizing risk to operatives, installations below and above
ground and members of the public. This Standard gives further
emphasis on requirements necessary to formulate a safety plan and
takes the reader through the risk assessment process to provide a
robust and comprehensive work plan for any of the techniques
Whilst it is recognised the planning of any works is essential,
due to the range of works covered the operational risks can vary
from technique to technique. Therefore much more guidance is now
given on operational safety for each of the techniques.
