		+	Laser scanning is a method of collecting surface data using a laser scanner which captures the precise distance of densely-scanned points over a given object at rapid speed. The process is commonly referred to as a point cloud survey or as light detection and ranging (LIDAR, a combination of the words 'light' and 'radar'). It can be used to generate 3D imagery that can be converted for use in 3D computer aided design (CAD) modelling or building information modelling (BIM).

Before construction work commences on site, it is often necessary to undertake a thorough site investigation. Approved document C, Site preparation and resistance to contaminants and moisture, suggests that the extent and level of site investigation need to be tailored to the type of development and the previous use of land. A thorough site investigation can remove many of the uncertainties that usually has big impacts on budgeting and risk in construction.

Site investigation can be carried out as a desktop survey or a site survey. There are several resources available to assist with site surveys.

= Historical maps =

Libraries can have copies of original land maps. The history of a site can indicate the previous usage and indicate any potential reasons for contamination. It can also indicate any underground obstructions by identifying previous constructed buildings. Maps can also indicate original boundaries, roads and walkways.

= Ordnance Survey maps =

The Ordnance Surveys provides mapping in the UK. The maps will give details on buildings, boundaries, structures or any roads and any other surrounding properties. The maps are available in various scales.

= Local authority archives =

The archives are a source of historical information which might include old maps, photographs, street records and other information that can be gained for the area of the project.

= Aerial photographs =

Specialist contractors can provide a service to produce scaled photographs for potential sites.

= Building and planning applications =

Local authorities have a planning application database where historical data of the site can be accessed and previous planning applications for the areas can be viewed. Information that can be gained is existing drawings for the current use of the site or any planning conditions or restrictions that might apply to the potential site.

= Online methodologies =

Online satellite maps are now readily available and it has become easier to access aerial photographs of potential sites. The maps can help with topographical details and heights and levels can be established by using shadows. The maps can also be used to establish potential tree preservation orders. Potential flood plane regulations can also be investigated.

An online address search can also reveal historical data on historical property values, previous usage of the site and any existing investigation reports.

= Site inspections =

A physical walk on site will be required to carry out site investigations to further enhance the desktop survey. Items that can be missed on aerial maps might be; trees and hedges, boundaries, services including pylons and phone lines and any other site obstructions. More detail site investigations will include soil analysis which will be carried out to establish the soil characteristics that will be required for designing the sub-structure. Trial pits will be used to gather samples that will be sent off for analysis.
