Arboricultural Method Statement for Construction Works Close to Trees

• Introduction

A Method Statement is a document detailing how a particular process will be carried out. In the arboricultural industry, such a statement is commonly used to describe how construction works can be carried out close to trees. It should include details on how the works will be managed and how the trees will be adequately protected during such a process. It is a document that many Local Planning Authorities (LPA) are now requesting as a condition of planning consent.

• Content

The method statement contains a timetable indicating when and how specific works adjacent to trees should be carried out. This will cover items such as the installation of protective fencing, hand excavation within tree protection zones, surface changes etc.

Engineering specification sheets should be included for items such as the design of protective fencing, special surfaces, methods of trenching etc. Bill of quantities for materials are also included where necessary.

Site supervision by an arboriculturist may be stipulated for some or all of the operations associated with trees.

• Items to include within a method statement
  • Schedule of Tree surgery works (prior to and upon completion of construction works).
  • Tree protection Zone (TPZ) (distances, type of fencing etc)
  • Specification for surface changes
  • Specification for level changes

  • Location of bonfires, chemicals etc
  • Contingency Plans (chemical spillage, collision, emergency access to the TPZ)
  • Post construction landscaping near trees.
