Abstract

The facade walls of ancient Russian landmark buildings built of brick or natural stone, are generally flat, have a complex relief created in order to obtain an effect of light and shade in side lighting. In the restoration, reconstruction, as well as new construction in retro style, this relief should be reproduced. The report describes the “flat” relief of the 19th century’s landmark building – the church in the Abramtsevo estate near Moscow. The surface was scanned with Trimble S6 electronic tacheometer with subsequent processing by 3D Reshaper Survey Bundle program and mathematical description of digital data using the theory of random functions. It was established that the wall surface can be modeled by a nonstationary random function with two harmonics. To realize a model in the masonry of the restored or reconstructed wall, the basic technology was proposed, which embraced techniques of researching, designing and reproducing the surface of an uneven facade wall.
