Layout Point: Reduce Construction Errors
The application is used for the correct positioning of foundations, floors, false ceilings, drywall studs, floors, walls, and in the MEP industry to determine the position of pipes, equipment, HVAC ducts or cable routes, supports and support elements, passage holes in slabs.
The working method is simple and starts with placing control points - references determined by the surveyor, which exist in the field and when added to the model will allow the synchronization of the model with the field situation and the correct orientation of the total station on the construction site.
Subsequently, points will be placed in the model for positioning either manually, practically anywhere in the model, or using specific points of construction elements - the corners of the slabs, axes, surfaces, walls, or any other object in the model. The points are identified by numbers with a prefix for easy identification, have a description, and possibly a role that can be specified by the user.
Revit allows the creation of families with positioning points (e.g. foundations) that will automatically populate the construction elements belonging to the same family throughout the project, regardless of size variations.
If Point Layout is used in Navisworks, the points are added to the coordinated aggregate model covering all specialties, benefiting from all BIM facilities, especially detecting non-conformities and construction issues in the virtual model before bringing the problem to the construction site.
Once the points have been added, they are exported in csv or dxf format to the control tablet. Communication between it and the total station will be done via Wi-Fi or Bluetooth connection.
The process can also take place in reverse, control points in the field can be collected and imported through Autodesk Point Layout and subsequently checked with the help of Navisworks, or used to create an As-Built.
The use of digital technologies in construction layout operations reduces risks and the number of high-impact errors. It also provides accuracy to the data coming from the design and allows contractors to install much faster and more
