AGS Permit to Dig
Permit to Dig for Intrusive Investigations – Introductory Notes
This document has been produced to confirm the hierarchy of responsibility to the point of breaking ground and ensure that all reasonable measures have been taken to establish and then avoid the risk of striking buried services. Its use is aimed at those sites where a Permit to dig has not been provided by the client, their agent or a contractor but could equally be used where information needs to be transferred within a single organisation.
The transfer of the document between parties is intended to physically represent the transfer of relevant information passed between parties. Whilst the information may pass between parties, this does not relieve any party in the chain of their responsibility to take all reasonable precautions to protect the workforce.
The Authority to Proceed should be completed by the holder of records of services affecting the site or by those who have obtained them. This could be client / consulting engineer / client’s agent or the supervising colleague within a single organisation.
When this section of the form has been completed, the form will be signed and passed to the site supervisor together with copies of the service drawings.
The Authority to Excavate should be completed by the supervisor who is responsible for the work that breaks ground. This could be a principal contractor’s representative, site manager or, within a single organisation, could be the engineer responsible for the work. The supervisor must, at this stage, review the service drawings, determine those that affect the work and confirm that Control Measure Nos 1 to 5 have been implemented and that the Mandatory Requirement Nos 1 to 3 have been met. Any special requirements should be recorded at this stage.
When this section of the form has been completed, the form will be signed and passed to the operatives undertaking the work at a pre-start briefing together with an explanation of the services present and the control measures implemented.
The Acceptance should be completed by the person responsible for the hour-by-hour supervision of the work. Examples are the lead driller on a cable percussion site, the engineer supervising window sampling or the foreman on a hand-dug trial pitting job.
In signing the form the signatory accepts that they will hold the responsibility for safely avoiding services and undertakes to carry out the work in accordance with the requirements set out on the permit.
On completion of the job the permit should be handed back to the signatory of the Authority to Excavate and then to the Authority to Proceed so that full traceability may be maintained.
