4) Website review technique
Fire load survey can be made through website information, as done by Bwalya [28]. Sale information listed on
the real estate websites usually offer the floor plan of the house or apartment with dimensions of the major rooms.
Digital photographs of various rooms provided can give a general picture of typical furnishings and their layouts in a
particular building category. In this technique, fire load is estimated according to these photographs. The application
of this method is limited because it is not easy to find a real estate website providing enough information you want.
And these photographs usually cannot show all the combustible items in a room, for example, contents in cabinets or
things hidden by others and there is a big uncertainty in estimating the mass and calorific value of these items just
through the photos. The surveyor’s judgment and experience will have great impact on the result.
