URN: LANTw6
Business Sectors (Suites): Horticulture,Treework

Overview

This standard covers the activities required to create and maintain open drainage systems to a given specification.

The specification will include the route, profile, depth and grade of the drain, together with the acceptable tolerances and the treatment of excavated material.

Drainage systems may be pre-marked by others but in many cases you will be required to mark the drains yourself. You will need to check for the presence of underground services.

You will also need to take account of any restrictions affecting the work e.g. designated sites, presence of listed structures, wildlife, non-native invasive or protected species etc.

You are required to avoid or minimise damage or disturbance to the surrounding area including trees, other vegetation, wildlife and habitats, or to any structures, fences, paths, and signs, and to ensure that other site users are not put at risk by your work.

When working with equipment and machinery you must be appropriately trained, and hold current certification, where required, in line with the relevant legislation.

Your work must conform to all relevant legislation and codes of practice, industry standards and guidance.

Glossary

Information required to carry out work activities could include:
• drawings
• plans
• schedules
• specifications
• method statements
• Standard Operating Procedures (SOPs)
• manufacturer’s instructions
