Specific course objectives

The purpose of this course is to provide the capability to survey buildings with on-site topographical and photogrammetrical methods (analytical and geometric image rectification). These methods allow the students to get a metric description of the surveyed buildings. The topography section contains both theoretical and practical lectures about the most recent technologies and equipment (Total Station). To support the image rectification a specific software will be available for the students during the lectures time. Most of the course is related to building modeling using the B.I.M. software Autodesk Revit Architecture that can provide a powerful design and illustration tool useful for the following courses that require a project presentation.

Course programme

Direct measurements processing

• Physical quantities and measurements.
• Conceptual scheme of a measurement.
• Arithmetic mean and Standard deviation of an n measurements series.

Topography.

• The topographical measurements: angles and distances.
• Polar and Cartesian coordinate systems.
• Topographical instruments getting building coordinates (Total Station).

Digital images and the basics of Terrestrial Photogrammetry.

• Digital photography: pixels and image discretization.
• Digital cameras operation.
• Rows/Columns grid in digital images.
• 3D Cartesian coordinates system of digital cameras.
• Digital images visualization on the computer screen.
• Coordinates transformation from the rows/columns to the Cartesian system.
• Basics of image rectification.
• Working with the RDF software to obtain metric representation of the building facade.

Building representation with Autodesk Revit Architecture.

• Building Information Modeling (B.I.M.) and the project items: system families and components, levels, instances, types.
• BIM and CAD: exporting and importing files.
• Site modeling.
• Creation of walls, floors, roofs and their properties.
• Structural components.

• Extracting information: measures, schedules and quantities.
• Managing views and creating sheets: plan views, sections, elevations, 3d views and detailing.
• Layout and print.
• Modeling a given building and creating architectural views.
