Assessment Guidance

Learning Outcome 1:

Learners will produce a drawing detailing the timber feature along with a specification for the materials to be used for the construction process. Learners will evaluate a range of timbers for proposed applications for timber landscaped features.

Learning Outcome 2:

Learners will set out and construct horizontal timber feature following specifications using a range of appropriate joints and techniques. They will set out and construct vertical timber features following specifications using a range of joints and techniques. Learners will identify and carry out repairs and maintenance of one horizontal or one vertical feature.

Learning Outcome 3:
Learners will investigate a range of timber preservative treatments and make recommendations of suitable preservatives for a range of timber types.

Learners will produce a COSHH assessment for a selected timber preservative application.

Learners will survey timber features and produce a five year maintenance plan for a vertical and a horizontal timber feature.

Aim

The learners will develop the knowledge to construct and maintain timber landscape features. The learner will construct and maintain timber landscape features.
