3D scanning of the hotel complex for reconstruction using BIM

Территория гостиничного комплексаIn November 2013 the Trimetari Company performed laser scanning of the hotel complex in Moskovskaya Region, Russia. The square of the territory for 3D laser scanning made around 2 ha, on this territory the interiors of all the buildings and constructions, as well as facades, basements and roofing were scanned.

The main problem to be solved with the help of laser scanning and BIM modelling is to provide up to date information on the condition of the whole object for the design of a large-scale reconstruction. The contracting authority used Autodesk Revit Software for the creation of BIM model from the point cloud data.       (read more…)

Laser scanning for intelligent modeling of Rostov Nuclear Power Plant

Fig 1 - Point cloud of The Rostov Nuclear PlantDespite the fact that the first ground-based scanners appeared back in the last century, one can hardly say that a 3D-scanning laser technology is widely used in the design and construction of industrial facilities. The main reasons are probably the cost of such systems which is still high and the lack of information about how to use them effectively in particular applications. Nevertheless, interest in this technology and demand for it on the market of surveying equipment is growing in geometric progression with every year, and the high cost of the acquisition is more and more compensated by the offers from scanning services providers.
Depending on the project goals and objectives, the laser scanning technology can be effectively combined with 3D-design technologies. (read more…)

3D Laser Scanning of the Monument of Vladimir Lenin located on “Ploschad’ 1905 Goda” Square in Yekaterinburg

3D model of the sculpture of Vladimir Lenin, obtained by laser scanning.The main square of Yekaterinburg city, which is called “Ploschad’ 1905 Goda“, had a lot of monuments during its lifitime. Before the revolution, there was the Cathedral on the square, and a monument to Alexander II was established in front of the Cathedral in 1906. In 1918, its place was given to the Statue of Liberty. Then, in 1920, the bust of Karl Marx was installed instead on the same pedestal. A few months later, the Monument to the Liberation of Labor was erected instead of the bust. In 1930, the Cathedral and the monument were blown up. A huge tribune was installed in the center of the square. Finally a monument to Vladimir Lenin was erected on the podium on November 5, 1957. The monument was designed by the sculptor Ingal. 

In 2013, the local Ministry of Culture decided to renovate the monument, which is an object of cultural heritage. Trimetari Consulting LLC was awarded a contract to make an architectural survey of the monument by means of 3D laser scanning. (read more…)

Laser Scanning Of The Copper Ore Quarry In The Middle Urals

3D model of the quarry, created by use of laser scanningIn 2013, Trimetari Consulting LLC in collaboration with The Institute of Mining of the Russian Academy of Science performed surveying of one of the copper ore quarries of UMMC in order to develop a methodology for monitoring geomechanical processes in the open-pit sides. The quarry is located in the Middle Urals, Russia.

Development of a Virtual 3D Model of Denisova Cave in the Altai Mountains for Virtual Environments and Web

Laser Scanning of Denisova Cave in the Altai MountainsDenisova Cave in the Altai Mountains (Siberia, Russia) is a world famous Paleolithic site (51° 23′ 51.29″ N, 84° 40′ 34.34″ E). Regular archaeological excavations are being performed here since 1982, more than 20 cultural layers were revealed, and more than 80000 finds were collected. In 2008, a new branch in human evolution was discovered based on finds in the Denisova Cave [1]. So it is an actual task to digitally preserve this unique object using up-to-date methods of 3D documentation: i.e. to create virtual (digital) 3D model of the cave and most important finds, and visualize results of archaeological research based on this model.

Architectural measurement of the fasades of several buildings at Lenina St in Murmansk

Measurement of facades by laser scanning in polar night conditionsAn excellent example showing the efficiency of ground-based laser scanning technology in the MobiScan mobile laboratory is the work performed by Trimetari specialists in December 2011 on architectural measurements of a complex of residential buildings in Murmansk.

The need to restore the facades of the buildings due to their technical condition and categorisation as monuments required careful measurements and identification of losses. The buildings are not distinguished by an abundance of decoration or complexity of forms, but their location (the central street of Murmansk), constant traffic and pedestrian flow, as well as the closure of facades with green plantings, required an ambiguous approach to solving the task. In addition, the scanning was carried out in winter, at sub-zero temperatures and in polar night conditions.
