Title:

Tree Risk Assessment

Description:

Request for Quotations

GENERAL INFORMATION

The City of Surrey is requesting quotations from urban forestry or arboriculture contractors to undertake tree risk assessments on trees managed by the Parks Division. The level of assessments required is taken from the International Society of Arboriculture’s standards for Tree Risk Assessment (TRA):

  1. Limited Visual Assessment
  2. Basic Assessment
  3. Advanced Assessment

Trees requiring assessments may be located within forested areas on parkland, engineering road allowances or City land. The tree risk assessor will be required to hike off-trail, through dense vegetation and difficult terrain to reach the tree(s) requiring assessment. The level of assessment required will be determined by the City, with maps and locations of trees provided digitally to the consultant. If the consultant identifies a tree that may require an additional assessment (i.e. advanced assessment- aerial, resistance drilling, root excavation) the information will be forwarded to the City for review and the additional assessment will be carried out only after approval by the City.

TRA’s are completed year round, with the majority of assessments falling into the “Basic Assessment” level of assessment. TRA’s are completed as a part of the following Parks Division’s programs:

  1. Scheduled tree risk program
  2. Demand tree risk program

The City will only pay for actual time worked, exclusive of lunch break. Two paid coffee breaks of 10 minutes is standard practice.

Note: The City will only pay upon arrival at the first job site of the day and only up to and upon leaving the last job site of the day. This means that there will be no “in and out” travel time charged to the City.

Note: The City will pay for any office time required to process the spatial and tabular data associated with the work.
