There have been important advances regarding the synergies between Building Information Modeling (BIM)as part of Virtual Design and Construction (VDC)and Lean Construction. However, the literature does not fully explore the nature of these synergies nor the conceptual reasons behind them. This better understanding of these synergies would allow the Architecture, Engineering and Construction (AEC) industry to achieve better Lean and VDC implementations and would provide a stepping-stone for the academia to continue building on these synergies. This article presents a thorough literature review based on leading international journals, conference proceedings and books, to explore the synergies between Lean Construction and VDC, including BIM (product), process and organization modeling. As part of this review, the article tests mechanisms about interaction mechanisms, previously mentioned in the literature. The findings indicate that using the entire VDC framework, the positive interactions between Lean and VDC increased significantly with respect to the same analysis restricted to the interaction between Lean and BIM. Identifying these new interactions and interaction mechanisms can help the AEC industry take a more holistic approach and generate improvements in every project phase.

In this study, a methodology for quantifying the historical value of the Cathedral of Christ the King, in the municipality of Huejutla de Reyes, Hidalgo, Mexico, was developed through application of historic building information modeling (HBIM) and conventional valuation methods. Despite many studies having been undertaken around the world, there remains a gap in that elucidating and unifying the relationship between HBIM and valuation is still difficult. The methodology developed in this study combined and used information captured via a Leica ScanStation C10 laser scanner, a drone, and a 360° camera. Various software programs were then used to combine the images with the scan data. HBIM facilitated automatic and accurate quantification of the amount of materials used to build the cathedral. A significant finding was that the use of HBIM enables a valuation to be obtained immediately. While the results must be regarded as being exploratory, they provide interesting insights into the synergy between HBIM and historical valuation. Another critical point is that this is, to the best of our knowledge, the first study to link HBIM with a valuation.
