Overview

Framework:
RQF
Level:
Level 3
Unit No:
D/617/1481
Credits:
6
Guided learning hours:
50 hours

Assessment Guidance

Learning Outcome 1:

Learners will undertake a survey on site to record topographical and dimensional data. The site data will be processed to produce an accurate scale drawing and level information. The processed data will be analysed for feasibility. Learners will evaluate how the site characteristics surveyed will influence the choice of landscape design.

Learning Outcome 2:

Learners will read and understand landscape design drawings and obtain setting out data using dimensions or scale. Learners will et out a landscape design using applicable methods. Learners will evaluate the setting out in terms of accuracy.

Learning Outcome 3:

Learners will produce and present a set of detailed construction drawings to an appropriate scale, with annotation and landscape features using suitable graphical symbols.

Aim

The learner will be able to survey a given site highlighting key site characteristics, set out a design and produce detailed construction drawings for specific features.
