The problem

Pipe installment often requires a post review process to verify proper placement. To guarantee the precise level of these elements, represents the fluid performance of the entire aqueduct and sewage system. At this phase of the project, to evaluate the alignment or adaptation of facilities to the model after its installation was crucial, to define the necessity of including costs in personnel programming.

Operation process & scope

Most pipe facilities in this project are executed by highly qualified personnel to prevent errors. Even so, the site manager expected to:

1. Test the quality of the As-built model for construction inspection
2. Upload models (BIM & POINT CLOUD) to execute the inspection on-site
3. After having results and activate the heat map in the point cloud to see is the elements are properly installed and aligned to the model
4. Share the inspection to the stakeholders


Correct updating of the BIM model of a Construction project during execution time is of the utmost importance. The majority of cases where a digital inspection is being helded, people tend to think that those technological processes can only be made by a BIM expert or a very qualified data capture specialist. In fact:

  • The inspection was performed by the site manager, and the system found the item just 5% within tolerance of the model. Thus, all the point cloud is in red representing the installed element distance from the model
  • The alignment of the water pipes inspected has been confirmed 8 time faster than in traditional review methods
  • The pipe is 10.05 ft tall, 3 in outside the tolerance of the planned element

The client verified all the water facilities of the plant under construction, the general result was good, finding a single element out of tolerance. Even so, the deviated pipe was higher than it should have been (9,8 ft high), and this not only implied extra costs of qualified personnel, said error also implies extra hours for the architect to update the BIM model.

Errors when pouring concrete in the structural phase of a project can represent high rework costs that can be prevented with the use of technological tools.

Correct leveling of elements in the construction process requires many hours of work by highly qualified personnel, representing a high cost of multiple revisions, before and after finding any deviation.
