  1. The Survey Surveying Equipment Measuring Calculations

  2. Dust mask Meter box key Extendable mirror Site notes Clipboard Binoculars Shoe covers First aid kit Surveying Equipment It is important you are able to access every (available) part of the property to conduct a precise, thorough and safe survey. For this you will/may need. • Ladders • Laser Measure • Digital camera • Compass • 30m Tape Measure • Short metal tape measure • Torch

  3. Surveying Methodology External inspection • Walk round the outside of the property first, if possible. • Note construction type • Clues to property age • Look out for and note location & types of vent, flues and AC Units etc • Externally measure property for area & heat loss wall calculations

  4. Surveying Methodology Inside the property • Choose a start point (downstairs, upstairs, loft) • Work Clockwise or Anticlockwise round the property • Make notes of number of rooms • Ceiling heights on each floor • Walls construction • Lighting • Heating System • Hot Water Systems • It is generally a good idea to follow the order of elements on the site notes

  5. Measuring

  6. Room Heights Simply measure floor to ceiling. Average for variations across a floor Always measure room heights internally

  7. External Measurements Externally there is no furniture to measure round, or internal walls in the way • A simple building with suitable access, can require as few as 2 external measurements • External measurements aren’t always appropriate: • Bad weather • Restricted access • Top floor flat

  8. Internal Measurements • Should be used for flats • Suitable for laser measuring devices • Must allow for internal partitions • Sometimes more appropriate for complex properties

  9. Property Measurement test Study the following property details Calculate floor areas and heat loss perimeter

  10. The house, a typical mid terrace property

  11. Floor plans Ground floor Calculate the floor area and heat loss perimeter First floor

  12. Area Measurements Ground Floor 5.7m x 7.51m = 42.81 Total Floor Area = 42.81m2 First Floor 5.7m x 7.51m = 42.81 Total Floor Area = 42.81m2

  13. Heat Loss Walls Ground Floor 5.7m + 5.7m = 11.40m First Floor 5.7m + 5.7m = 11.40m

  14. More Complex Property Measurement Looking at the following plans, decide the best/easiest way to measure the property to calculate areas and perimeters.

  15. Measuring a Property

  16. External Measurements

  17. Internal Measurements

  18. Bay windows 2.02 1.0 Ceiling height 2.6m Porch and Bay Window

  19. Porch and Bay Window

  20. First Floor Area

  21. Bay window area 5.3 2.02 1.0 • Bay window area for canted bay = Wp(width partial) x D • 2.02 x 1.0 = 2.02m2 • This figure should be added to the total floor area for the ground floor There is a full list of the calculations for all 6 bay types in your pack

  22. Total Ground Floor area

  23. Heat Loss Perimeter – Bay Window 5.3 2.02 1.0 Heat loss perimeter: This is calculated as the extra HLP for the bay window. The HLP for the wall is measured as normal, the additional HLP of the bay is added to this figure. Please refer to the bay window calculation sheet for guidance. HLP = total wall length + extra perimeter (0.8 x D) HLP = 5.3 + (0.8 x 1) HLP = 6.1m

  24. 2.0 1.0 1.0 2.02 11.5 Perimeter of front wall: 11.5 + extra perimeter for porch + extra perimeter for bay window 11.5 + (2.0 x 1) + (0.8 x 1) = 14.3m Heat Loss Perimeter

  25. Front wall = 14.30 Left wall = 8.00 Rear wall = 14.30 Right wall = 10.00 Total HLP = 46.6m Total Ground Floor HLP

  26. Total First Floor HLP First floor perimeter = 8 + 6.2 + 2.0 + 5.3 + 10 +11.5 = 43m

  27. Integral Garage • An integral garage should not be included in the floor area • The walls adjacent to the integral garage are classed as heat loss walls • What is the Area and HLP for this floor? 8 Main House 3 8 Integral Garage 4

  28. Area &HLP – Integral Garage Area = (8 x 8)-(4 x 3) = 52m HLP = 8 + 8 + 4 + 4 + 5 + 3 = 32m Or = 8 x 4 = 32m 8 Main House 3 8 Integral Garage 4

  29. Heat Loss Perimeter - Conservatory 5 Conservatory 3 Main House 7 • Calculating the HLP for a property with a conservatory • Non-separated – adjoining wall is not included in HLP • Separated – adjoining wall is included in HLP

  30. Habitable Rooms • A habitable room is a room which is lived in they include: • Lounge • Dining room • Bedroom • Study • Kitchen diner • They do not include: • Bathroom • Kitchen • En-suite • Hallway • Stairs • Utility room • Store rooms • Garage • Any room without a window

  31. Habitable Rooms • For a kitchen to be classed as a kitchen diner there must be space for a table and 4 chairs • Where a door between two habitable rooms has been temporarily removed they are still classed as two habitable rooms • Where a door has been permanently removed, i.e the hinge holes filled in, they are one habitable room • A non-separated conservatory is classed as a habitable room if there is an internal quality door between the conservatory and the dwelling
