Install small element kerbs and edge restraints
Overview
This standard is for those who install small-element kerbs and edge restraints that are used within the hard-landscaping industries.
It is suitable for operatives working under limited supervision and focuses on the skills required both to understand the structure and undertake the installation of edge restraints while working to specifications.
You will be expected to understand the impact of the installation work on the immediate environment, and the impact of the environment on the structure.
Performance criteria
You must be able to:
- assess the risks associated with the site and the proposed work
- select, prepare and use tools and equipment for the installation of small-element kerbs and edge restraints safely and correctly
- set out for line and level
- place and prepare a suitable bed for installing small-element kerbs and edge restraints
- lay units to the correct line and level
- cut in units to required specifications
- maintain correct joint width
- check completed installation of small-element kerbs and edge restraints for compliance and rectify any problems
- haunch units
- minimise damage, unnecessary waste, unwanted impact on the environment and pollution when installing small-element kerbs and edge restraints
- keep the site in a clean and tidy condition
- clean, maintain and store tools and equipment after installation of small-element kerbs and edge restraints promptly and securely
- protect small-element kerbs and edge restraints correctly against weather and use until they are in a suitable condition
- leave the site safe, tidy and suitable for intended use
- maintain working relations with those involved in, or affected by, the installation of small-element kerbs and edge restraints
- maintain communication with those involved in, or affected by, your work
- carry out your work in accordance with relevant environmental and health and safety legislation, risk assessment requirements, codes of practice and organisational policies
Knowledge and Understanding
You need to know and understand:
- the weather conditions that are appropriate for installation of small-element kerbs and edge restraints
- how to interpret small-element kerbs and edge restraint installation specifications
- how to measure to ensure work is within tolerances
- how falls, lines and levels are determined and set out
- how to select, prepare and use the correct tools and equipment for installation of small-element kerbs and edge restraints, including personal protective equipment (PPE) and respiratory protective equipment (RPE)
- how to maintain, clean and store the required tools and equipment correctly
- the range of small unit kerb systems and other suitable units that are available and their suitable applications
- the importance of robust edge restraints
- the importance of using the correct type of bed material
- how the bed is placed and prepared, and how it is shaped to follow summits, hollows and transitions
- the pros and cons of using fresh windrow bedding and pre-placed races
- how to calculate the number of units required
- how units should be stored on-site, how they are delivered to the laying face, and how they are positioned for the laying operative
- the pros and cons of both butt-jointed and mortar-jointed installations
- how units are consolidated to the required line and level
- how edge restraints are checked for accuracy in alignment along both straights and curves
- use of cutting tools including guillotine, saw and trimming tools
- the importance of dust-suppression and respiratory protective equipment (RPE)
- the removal and replacement of defective units when using a cut-off saw
- the importance of maintaining communication with those involved in, or affected by, your work and how this should be done
- the importance of following relevant environmental and ecological best practice to help minimise the impact of your work on the environment
- your responsibilities under relevant health and safety legislation, codes of practice and organisational policies
