Definitions
Company requirements include the policy, procedures, and methodologies of the
company. They include legislative and regulatory requirements, which may apply
across the company or to a specific site. Requirements are documented in the
company’s health and safety plans, traffic management plans, contract work
programmes, quality assurance programmes, policies, and procedural documents.
Infrastructure pipelaying refers to the installation of infrastructure pipes, fittings, and
associated structures in the road and elsewhere, normally beyond the boundary of
private property. Infrastructure pipes include sanitary sewage and stormwater, and
may include pipes or ducting for other services such as potable water, gas,
electricity, or telecommunications. For the purposes of this unit standard it does not
include the commissioning of the pipes or the installation of services they may house;
nor does it include jointing required to be carried out by a licensed specialist.
