BS5837:2012  Compliant  Tree Survey Reports with  AutoCAD plans, various visuals available.*

Pre-Development Survey (BS5837:2012) with tree constraints plan 

This offers a cultural assessment of the existing trees within a development site to identify their condition and retention potential. The information is provided in accordance with BS5837:2012 and allows for the identification of development windows within the proposed site which will inform its design, hence avoiding critical problems occurring at a later stage of the development.

On site and off site trees are assessed as detailed within BS5837:2012. Specialist  tree plotting  software enables professional digital plans in AutoCAD to be provided working seamlessly with Architects.

Many local authorities require this type of inspection before any design is initiated, and this will often form part of the supplementary planning guide (trees and development). An arborist would be able to disseminate the information required by individual planning authorities in relation to trees and development sites and therefore prevent unnecessary costs to the developer.


Arboricultural Implication Assessment (AIA)

The assessment indicates which trees are likely to be affected in a development. In basic terms, which trees ‘will have to go’ with the proposed layout/design, which can be saved and protected, and which trees require specialist protection or build methods.

The implication assessment can identify where damage cannot be avoided, and may pinpoint special construction or engineering techniques necessary to prevent damage. The report would also indicate essential tree works required, allowing the development to continue, and supplementary considerations required where trees are lost.


Arboricultural Method Statement (AMS)

Following an implication study or pre-development survey, an arboricultural method statement would set out the processes required to initiate and manage tree protection areas. This would include a schedule of tree works for both safety and enabling, the position and type of fencing required, and any additional surface protection required should the construction stay into protective areas e.g., access routes, storage / wash out areas and post development site treatment.

These statements are often required as a planning condition to ensure that developers take the necessary precautions in respect of trees / roots and avoid unnecessary conflict with trees or restrictions in work practices.

We work for private clients as well as large commecrical developers often working as part of a design team.  Building near trees can be done with specilaist help and advise please contact us to discuss your next project.
