Site Survey

Site Analysis prior to purchasing a building site it is essential to conduct a thorough survey to ascertain whether the site characteristics suit the development concept. The following guidance forms a basic checklist:

  • Refer to Ordnance Survey maps to determine adjacent features, location, roads, facilities, footpaths and rights of way.

  • Conduct a measurement survey to establish site dimensions and levels.

  • Observe surface characteristics, i.e. trees, steep slopes, existing buildings, rock outcrops, wells.

  • Inquire of local authority whether preservation orders affect the site and if it forms part of a conservation area.

  • Investigate subsoil. Use trial holes and borings to determine soil quality and water table level.

  • Consider flood potential, possibilities for drainage of water table, capping of springs, filling of ponds, diversion of streams and rivers.

  • Consult local utilities providers for underground and overhead services, proximity to site and whether they cross the site.

  • Note suspicious factors such as filled ground, cracks in the ground, subsidence due to mining and any cracks in existing buildings.

  • Regard neighbourhood scale and character of buildings with respect to proposed new development.

  • Decide on best location for building (if space permits) with regard to cut and fill , land slope, exposure to sun and prevailing conditions, practical use and access.
