UFG Drawing Guidelines:

Please would you ensure that where possible; the AutoCAD compatible *.dwg ‘Existing and Proposed Site Layout Plans’ to be provided, follow the bulleted list as below. Thank you for your assistance.

UFG Drawing Guidelines:

UFG is currently updating these ‘UFG drawing guidelines’ as seen below; to enable the use of OTISS tree surveying software, that uses a Global Positioning System [GPS] system to collect the tree survey data during the site visit.

  • The OYISS system requires that any *.dwg site plan/s provided to UFG are free of any unnecessary objects and details, so that a simple uncluttered *.dwg site plan is provided that must include the Ordnance Survey [O/S] 6-digit national grid Northings and Eastings co-ordinates, without alteration to the grid scale.
  • The *.dwg site plan should be less than 1-kilometre in width. Where site plans are greater than 1-kilometre in width, they will require being providing in sections that are less than 1-kilometre in width, to enable the geo-referencing, before UFG site visits can be undertaken.
  • The existing site and proposed site layout plans are required at the same scale and orientation’, centred in model space.
  • 'The existing site and proposed site layout plans (including any other required drawings e.g. elevations / cross sections etc) are received correctly scaled within a paper-space border, clearly stating the drawing scale, paper size, dates of any revisions and revision notes etc.
  • Clearly illustrate the numbers of trees present within and influencing the site to the BS 5837 [2012] standard, site boundary, drawing scale, north direction, papersize, and please include fixed measurements in metres.
  • Contain brief clear details of the proposed development including; alterations to ground levels, built up ground, subterranean [underground structures] such as service layouts, swimming pools, sunken driveways and garages.
  • All elements should be unblocked [Layers connected to other layers that shouldn’t be there].
  • Any redundant xrefs references and or html links need to be removed.
  • A key that clearly identifies all relevant site features including trees, shrub masses and hedge layouts should be included.
  • Ensure that all the drawing elements (E.g. drawing lines, site layout, building outlines, roadways, services, street furniture etc) are all located on their correct layers.
  • Any remnants’ and /or fragments of previous drawings are removed.
  • Areas of hatching are not connected to other layers.
  • Site plan / *.dwg files to be drawn in black and please where possible do not use unclear colours e.g. yellow outlines and yellow text. If *.dwg files are received incorporating multiple colours, UFG may be required to convert coloured lines to black to clearly assess the drawing provided and re-present it clearly in relation to the tree survey, associated arboricultural method statement, impact assessment, tree protection plan and any required landscape design work.
  • Please ensure all drawing elements are unblocked and that UFG does not need to use the explode function if possible.
  • Any Client proposed landscaping must be on its own layer, than can be switched off.
  • Where a paper site plan is received by UFG that has been drawn by hand, vectorised and / or has been converted / provided to a PDF format , any subsequent tidy up, re-scaling, tracing and where applicable re-draw work will be charge for pro-rata as set out in s13. Business rates:
  • Work involved in transferring any marked up information from the drawing quoted for or currently being worked on, on to any other drawing / revised site layout plan received during the works.
  • If a drawing program is being used other than AutoCAD it is the Clients responsibility to ensure that the drawing in question including any future revisions are converted in to the latest version of AutoCAD and checked as above, prior to it being sent to UFG as a *.dwg file.
  • All of the above apply to any revised or new drawings provided to UFG to be worked on.
  • UFG emails *.dwg files using the latest version AutoCAD drawing software and cannot guarantee all elements will remain as set out if used on another software program or a previous version of AutoCAD.

I have as the Client / Clients agent and as best possible, followed the above drawing guidelines and please find attached the *. dwg site plan as requested.

Why do *.dwg ‘Site Plans’ need to be provided in this format:

As Urban Forestry Group has not produced the drawings provided, Urban Forestry Group does not know which elements are on which layer.

It is impractical to go round and click on every individual element [e.g. building outlines, site layout, hedgerows, street furniture, walls, steps, trees, manholes, services, drainage, gulleys and levels] within the *.dwg drawings provided, to assess which layer each element is assigned too and which may be required to be retained or modified to complete work to the required standard.

Following the ‘UFG Drawing Guidelines’ can assist in reducing any unforeseen delays and also remove any possible ‘supplementary costs’ to resolve any site plan drawing issues, whilst undertaking the work.

As an Example: Where a ‘previous building layout’ has been drawn and not correctly assigned to its own individual layer, as is the recognised method of using the layers facility on electronic drawing programs.

Clicking on elements in the drawing to determine which element is assigned to which layer can be unpredictably time consuming and is unfortunately the only accurate way of checking that the work produced is correct.

If you are unable to provide the *.dwg site plans following the ‘UFG Drawing Guidelines’ as above; Urban Forestry Group can undertake any of the above work for you and will be happy to discuss this with you if required.
