This article presents the results of integrating hybrid-surveying technologies
(3D laser scanning, photogrammetry) to capture the real state of a historic building on the
campus of the University of Southern California in Los Angeles aiming to create its BIM model.
The case study is a two-story building, built in 1964 in modernist language, with apparent
steel structure, considered historical heritage recently. The adoption of hybrid approach was
guided on the following criteria: accuracy of data collected; level of detail required for each
element of the building; effort to acquire and post-processing of data; and accessibility to the
element to be captured. Taking into account the results obtained, we present the evaluation of
the tools and strategies used to acquire the building’s spatial data, according to the following
criteria: scale, complexity and range of equipment. The point clouds three-dimensional
model, generated by the capturing tools, forms the basis for creating a semantically oriented
building information model. BIM is a potential tool to produce a comprehensive inventory that
considers the unique maintenance requirements of historic buildings. This article intends to
contribute to the discussion on the adoption of BIM in the heritage area.
