Concrete strength assessment - cores and indirect methods

Standard details

CITB has developed this standard in discussion with industry

Duration

1 day of 6 learning hours

Purpose/Scope

The purpose of this standard is to provide the delegates who supervise assessing hardened concrete for strength onsite primarily through core testing but with reference to other indirect non-destructive testing (NDT) methods.

Scope:

• characteristic strength of concrete
• assessment of strength when concrete supply is in doubt
• assessment for strength of specific locations where no information available
• principles of core and NDT methods
• planning for test locations and numbers
• assessing core results
• assessing in-direct NDT results
• assessing core results in conjunction with in-direct NDT
• review supplier and site pour records
• actions in the event of non-compliant concrete

Occupational relevance

Training delivered against this standard would be relevant to the following occupational group(s):

• supervision
• management and leadership.

Candidate pre-requisites

There are no delegate pre-requisites as part of this standard, however a basic knowledge of concrete terminology and techniques would be beneficial.

Instruction/Supervision

As a minimum, course trainers must be able to demonstrate that, in relation to this standard, they have:

• an award in education and training (or equivalent, as per requirements for approved training organisations)
• successfully completed training to this standard
• at least 2 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 delegates to achieve learning outcomes and must comply with relevant legislation.

The class size and delegate/trainer ratio must allow training to be delivered in a safe manner and enable delegates to achieve the learning outcomes.

The following delivery methods may be used in the delivery of this standard:

• classroom

This standard is considered to contain 51% or more theoretical learning.

This standard is considered to be set at a basic level.

Assessment

Methods of assessment considered appropriate for training delivered against this standard are:

For the successful completion of training, delegates must complete an end of course practical assessment or knowledge test that measures all learning outcomes and has a pass or fail criteria.

Where this training is assessed using multiple-choice questions, a minimum of 10 questions must be asked and delegates are required to achieve an overall pass mark of at least 80%.

Quality assurance

Assured

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 refresher requirements for this standard.

Classification

Lifetime

(Please note standards using this classification will only be grant aided once per delegate)

Approval date

December 2021

Review cycle

On request or 3 years from approval date.
