Point Cloud to BIM modeling services make it possible for AEC surveying companies to base their designs on actual as-built dimensions and conditions of a site or structure, as contained in 3D models which have been digitally reconstructed from laser scan data. This ensures a high rate of success in designing for renovation or retrofit projects.
AEC surveying companies often struggle in renovation or retrofit projects lacking proper documentation. In culturally sensitive projects, quite often, missing or damaged structures need to be reconstructed and their signature architecture restored, without detailed plans to go by. Point cloud data obtained from laser scans and photogrammetry go a long way in bridging the information gap when the data is properly converted to 3D BIM models.
Survey firms employ technically proficient service providers to convert point cloud to Revit models. They help surveying companies detect the actual measurements of hard to reach or concealed structural elements
BEING THE SURVEYOR OF AN AIRFORCE BASE DURING THE 1980âs
 Introduction
 The South African Defence Force, now the South African National Defence Force (SANDF), was involved in a Bosoorlog or Grens oorlog (Bush war or Border war)1 from 1966 till 1989.
 In order to protect the most northern borders of South Africa, a number of smaller, shorter perhaps, airstrips or airfields, sometimes referred to as tactical airfields, were constructed or in some cases upgraded.
 Examples of the above are Ellisras, Punda Maria (in the Kruger National Park) and then a full scale air force base with a 4000 m runway at Louis Trichardt.
 The construction at Louis Trichardt was given the project name Braambos.
 A Little Bit of Background
 I joined the South African Airforce during June 1972. My initial mustering was Construction Machine Operator and I was deployed at 402 Airfield Maintenance Unit (402AMU) with head quarters at air force base Ysterplaat in Cape Town. I completed the training course on 11 February 197
