Setting out for structural timber frames
Overview
Standard details
CITB has developed this standard in discussion with industry
Duration
Minimum 3 days of 6 learning hours
Purpose/Scope
This standard will provide the attendee with the information and skills too accurately and safely lay-up timbers for a simple oak frame timber structure.
The scope of this standard covers:
- personal protective equipment (PPE)
- respiratory protective equipment (RPE)
- reading drawings
- timber elements
- cutting lists
- defects and orientation
- setting-out
- chalk or ink lines
- lay-up primary timbers
- loft secondary timber members
- scribing methods
- marking out
Occupational relevance
Training delivered against this standard would be relevant to the following occupational groups:
- operative and craft
Candidate pre-requisites
It is expected that the candidate will be employed within the oak frame industry or have significant relevant carpentry experience.
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 10 years relevant industrial experience
- a verifiable CV
Delivery
Delivery may be in an on or off the job environment.
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.
The following delivery methods may/may not be used in the delivery of this standard:
- classroom
- workshop
This standard is considered to contain 51 per cent or more practical learning.
This standard is considered to be set at an intermediate level.
Assessment
For the successful completion of training, candidates must complete an end of course practical assessment and 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 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 is no mandatory renewal or recommended refreshment requirements for this standard.
Approval date
April 2019
Review cycle
Either on request or in 3 year(s) from approval date.
