Unit 7 – Construction and maintenance of buildings
Assignment 1
P1.1:
Desktop Surveys – This survey takes place before the site has been visited and before construction has begun which is during the very early stages of planning. The survey involves a number of different things like the internet, books, maps, geological maps and council offices which all play a part within the survey. A good starting point is to consult a number of large scale maps of the proposed site to check the site boundaries, building lines, existing buildings and other man-made, or natural, features which will affect the future buildings. A comparison with older maps may give some clues to determine former use and potential hazards that may arise.
Walk over survey – This is one of or the first site visit and it involves checking over the site. The physical nature of the site is also looked upon to see if there is any wildlife living there or not as precautions would have to be made to transport the habitats or move sites. The walk over survey enables much of the material discovered in the desk study to be confirmed or further investigated and also identifies other potential hazards that may arise. The surveyor can collect photographic records of the site during the survey for later examination. This also gives the surveyor/ engineers the opportunity to make detailed drawings of all those items including trees, existing buildings, watercourses, etc. which will result in implications for the building design.
Ground investigation – This happens once the walk over survey has provided the all clear for the site and it involves taking samples of the soil to see if it’s good enough to build on etc. As far as low rise housing is concerned its main objective is to determine whether strip foundations will be suitable and whether they can be designed in accordance with the simple rule of thumb approach contained in the Strip Foundations section. 4 metre max trial pits are made by hand or machine to
