Procedural Guide - Book - Page 9
Guidance
Information and instruction on how to apply the requirements within standards or
procedures. Guidance is consensual information that originates from any one of
several different professional organisations and provides technical information about
safe practices and procedures.
Hold point
A stage in the temporary works process where no further progress is to be made until
the necessary permit or action has been completed.
Hydrostatic pressure
The pressure exerted by water due to the force of gravity, proportional to its depth.
Implementation plan
A document (or set of documents) that covers the erection/assembly, use, unloading
and dismantling of the temporary works, including which inspections, checks, hold
points, permits and certifications are required. This may consist of the method
statement, task- specific risk assessment, inspection and test plan, checklists and
other certification.
Implementation risk
The combination of execution risk and consequence of failure risk.
Implementation risk
class
Implementation risk is formed from a combination of execution risk and consequence
of failure risk. It may be set out as very low, low, medium or high.
Inspection
An examination by a competent person to make sure that the (temporary) works meet
a specified standard, and to identify any risks that are present and decide on the
measures required to control those risks.
Inspection and test
plan
The documented planning of inspections, tests, checks and surveys to ensure the
correct implementation of a process, including temporary works installations.
Kentledge
Material placed on a structure to provide stability by the action of its dead weight.
Lacing
A component placed horizontally to strengthen a framework, generally providing
lateral stability.
Lateral restraint
Internal or external structures used to prevent lateral/horizontal movement of a
structure against horizontal forces.
Lateral stability
The application of lateral force-resisting systems to prevent lateral movement in the
event of lateral loads such as wind, concrete pressure, kinetic energy from
construction operations.
Limit-state design
A reliability-based design process that accounts for uncertainties associated with
strength properties and applied loads.
Load path
How the loads on the structure are transferred through the structure.
Made ground
Typically used to refer to an area of ground that has been filled, for example with
debris or rubble, as opposed to ground in a natural state.
Newton
The unit of force, 1 N is the amount of force required to produce an acceleration of
one metre per second squared on a mass of one kilogram.
Node point
The point at which two or more components connect to transfer forces.
Non-cohesive soil (or
cohesion- less soil)
A soil that does not exhibit cohesion (see 'Granular soil').
Overburden
Refers to any of the following:
Loose, poor quality material overlying rock in a quarry.
Term for weight of soil when calculating pressure.
Layers of earth and rock that have to be removed to get to formation level.
Peat
The surface organic layer of soil consisting of partly decomposed organic matter in the
region of 20% to 60%, depending on which authority's definition is used. Peat is
structurally weak for loading.
Peer review
A review of the (temporary) works carried out by independent person(s), separate
