Q: How many/which trees will I need to survey?

All trees in the proximity of the proposed development including nearby neighbouring trees. Roots can spread for more than twice the height of the tree and they don't stop at boundaries so there may be trees in neighbouring gardens that would be also be affected.
Q: What is BS5837?
BS5837:2012 Trees in relation to design, demolition and construction - Recommendations' is the British Standard specification for tree surveys, Arboricultural Implications Assessments (AIA) and Arboricultural Method Statements (AMS).
Q: What is an Arboricultural Implications Assessment?
An AIA details which trees are likely to be affected by a proposed development.  The plans will show which trees are to be retained and any that are to be removed.
Q: What is an Arboricultural Method Statement?
An AMS sets out the measures that will be implemented to protect the retained trees during construction. This may include specialist foundation construction to prevent root damage.
 Q: How close to a tree can I build?

There are many factors to consider when building close to trees including species, vigour and size of the tree and ground conditions such as existing foundations, hard surfacing and soil type. Digging foundations close to a tree may damage its roots endangering its health and stability.  Typically, 90% of a trees roots are in the top 60 centimetres of soil so digging a trench for services or foundations can have catastrophic consequences.

Building close to a tree may have future consequences for your property as roots and branches grow and spread.

A tree survey will specify the radius of the root protection area (RPA) which is the minimum area of undisturbed soil required to give a tree a reasonable chance of survival.


Q:  Can you provide a tree condition report for my mortgage company?
Possibly. Sometimes mortgage companies will ask for a tree report before they will approve funds for a property. We can provide a report stating the condition of trees at a property. This is an above ground inspection of a tree's condition and may include recommendations for tree work. There is no assessment of the tree below ground level and no assessment of any potential impact on foundations.  We recommend you clarify your mortgage provider's requirements to make sure a tree condition report would meet their needs.

Q: I have cracks in my property. Are the trees causing the problem?

Possibly. Some soil types will change in volume depending on their moisture content.  If your house is built on shrink/swell clay you may have some seasonal movement between drier summers and wetter winters.  In recent years the East Midlands has experienced extended dry periods and the presence of trees may aggravate the situation. If you have cracks you should contact your insurer and they will engage a structural surveyor to establish the cause of the movement.
Q: Do you do Structural Surveys?
We do not carry out structural surveys or below ground investigations. For this you will require a structural surveyor with specialist understanding of soil types and foundations.
Q: Can you provide a risk inspection report for the trees on our village green?
We don't carry out risk assessments on trees. Predicting the safety or failure of trees in public places is a very specialised area. It may involve techniques such as tomography, thermal imaging or core sampling. You will find an appropriately qualified consultant on the Arboricultural Association website.
