Risk Assessments


Our surveyors are trained and registered users of the Quantified Tree Risk Assessment method (QTRA). This is a systematic and transparent approach designed to allow the quick evaluation of the hazard presented to persons or property by trees. Using this methodology, only trees subject to recommendations are those presenting unacceptable hazards.

As a target led assessment (i.e., we focus firstly on what can be harmed or damaged), the volume of related tree work for a given area is often less than that produced by other survey methods. The cost of managing your tree stock is therefore reduced. As our company policy is to avoid all potential conflict of interest involved in tendering for works recommended in our surveys, we are able to guarantee to our clients that we do not specify unnecessary work for reward or profit.

T1Our tree work specifications are detailed, fully compliant with BS3998: 2010 and bespoke to individual trees. This avoids further generalisation and the associated problems of imprecise works. Contractors can price accurately and tenders can be compared more effectively. To enable this we can provide contractor’s packages, including work priority schedules, colour coded plans and even grid reference data where appropriate. Our work priority scheduling strives to be achievable rather than setting arbitrary and unlikely timescales.

We can undertake valuations for controversial, prominent trees using recognised methods to inform and justify cost/benefit decisions. These can also enable an assessment of the value of work to tree populations, informing wider asset management on a comparable baseline.
