Speakers Bio & Abstract

Prerna Sidharth Principal Architect and Partner
Archisolutions, Bangalore

BiographyHaving completed Bachelor of Architecture from Bangalores prestigious BMSCE college in 1999. She founded Archisolutions along with Architect B S Sidharth in 2009.The multidisciplinary firm was established with the intent to provide complete high level design service.

As a result of varied experiences accumulated from the field and with a determination to make a change in the approaches followed in contemporary practices, she implemented BIM as early as 2010 in the office and pointcloud conversions to CAD/BIM in 2015, her experience ranges from projects including Hospitals, Commercial to Residential interiors, Entertainment and Qsr's.Abstract LIDAR/3D LASER SCANNING IN BUILDING CONSTRUCTION WORKFLOWSThe first step to adopting laser scanning is understanding where it fits into the design and construction process and the value or return on investment.

In the As-Built or Renovation process: Most as-built drawings are inaccurate or incomplete.

Due to its high level of accuracy point cloud based as-built drawings and 3D models can improve design by analyzing clashes between newly designed elements and existing conditions or by evaluating alternative designs prior to construction.The accuracy of dimensions obtained from laser scans can also help improve planning by providing exact measurements for demolition and removal of components,as well as for prefabricated materials,minimizing waste and changes in the field.

If no models or drawings exist, the scan data can be utilized as a base to create the new documentation of As-Built.

2.In Design and Construction process:

Construction costs and waste are at alarmingly high rates. The balance between speed and quality is difficult to achieve. Automated quality assurance tools provide valuable insights that help contractors plan better and head off problems before they materialize on the job site. One of the simplest and most valuable laser scanning applications is scanning during the construction process to validate that the work put in place is as designed.

If laser scanning is used throughout the entire construction project, the new facility will have as-built documentation from all the major milestones in the project, creating a data base of what is behind the walls, above the ceilings and under the floor slabs for owners to utilize throughout the life-cycle of the building.Which is turn invaluable in facilities and asset management.
