3D laser scanning can be useful in adapting old structures
(as-built construction) for new purposes. Through the use of LIDAR technology, TruePoint captures point cloud data and uses software to analyze it. Point cloud data services can be especially useful in clash detection.

The 3D laser scanner identifies point clouds of existing pipes, motors, boilers, or other equipment, and TruePoint’s software analyzes the point clouds to define where new devices can be constructed without obstruction.

According to The American Institute of Architects (AIA), change orders account for 3 to 5% of total construction costs.  These costs are often equally distributed between the following:

1) Errors and omissions
2) Field conditions
3) Owner requests

For a $10,000,000 project, that could equate to $500,000 in additional costs, not to mention schedule delays and general frustration among the project's team members.

However, laser scanning can help minimize all three  categories of change orders.  Laser scanning gives the design team more information up-front, which allows design decisions to happen sooner and makes for a more complete set of bidding drawings.  This, in turn, allows contractors to have confidence in their bids, to fully utilize BIM for virtual construction, and to prefabricate more of their products—all of which, in the end, allow contractors to meet critical path schedule dates, as well as limit both re-orders of materials and delays due to unforeseen field conditions.

In addition: 

1) Owners can reduce their costs and tighten their schedules.  Furthermore, owners will then have better control over all categories of change orders, allowing for more prudent negotiations and discussions regarding the captured information.

2) Architects and engineers can make critical design decisions sooner and with more complete and accurate information.  Additionally, they can creatively utilize the point cloud data directly for construction documents, minimizing their drawing or modeling hours. This, in turn, results in a reduction of both RFI’s and change orders related to field conditions, as well as a reduction in errors and omissions.

3) Contractors can streamline their construction process and prefabricate more materials off-site.  This can result in reduced labor costs, fewer schedule delays, and the satisfaction of delivering a project on time and under budget.
