CITB has developed this standard in discussion with industry
Duration
Minimum half day of 3 learning hours
Purpose / scope
The purpose of this standard is to provide the candidate with the knowledge to prepare a roof deck substrate for installation of a single ply roof.
The scope of this standard covers:
- safe access and working practices on different types of roof
- temporary protection methods for a roof
- working with other trades
- how to prepare roof deck substrates including fixings, vapour control layers, and insulation for:
- profiled metal;
- in-situ concrete;
- screed over pre-cast concrete;
- timber panels;
- woodwool slabs; and,
- existing built-up and mastic asphalt roof for an overlay
- materials: handling, storage, and estimating
- main legislation, codes of practice, standards, and guidance
Occupational relevance
Training delivered against this standard is relevant to the following occupational group(s):
- operative and craft
- supervision.
Candidate prerequisites
There are no candidate pre-requisites as part of this standard. However, a basic knowledge of single ply roofing terminology and techniques would be beneficial.
Instruction / supervision
As a minimum, course instructors must be able to demonstrate that, in relation to this standard, they have:
- A train the trainer or instructional techniques course certificate
- Successfully completed training to this standard
- At least 2 years relevant industrial experience
- A verifiable CV.
Delivery
The following methods may be used in the delivery of this standard:
- classroom and / or workshop
All materials and equipment must be of a suitable quality and quantity for candidates to achieve learning outcomes and must comply with relevant legislation.
The class size and candidate/instructor ratio must allow training to be delivered in a safe manner and enable candidates to achieve the learning outcomes.
This standard is considered to contain 51 per cent or more theoretical learning.
Assessment
For the successful completion of training, candidates must complete an end of course practical assessment or knowledge test that measures the learning outcomes and has a pass or fail criteria.
Quality assurance
Quality assurance against this standard will require initial approval of the training organisation and their content mapped to the standard.
CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the training organisation can meet the requirements of the Training Standard.
Approved training organisations (ATOs) will be required to present information on records of training and assessment upon request to CITB for desk-based analysis. They will also be visited annually by the CITB quality assurance team.
Renewal/refresher
There are no mandatory renewal or recommended refreshment requirements for this standard.
Approval date
November 2018
Review cycle
Either on request or in 3 years from approval date.
