The purpose of our work was to search for possible options for the secondary use of destroyed brick buildings and structures. We conducted tests to verify the strength characteristics of bricks taken from the sites of reconstruction and complete demolition of buildings and structures. In the course of which, conclusions were drawn about the possibilities of further use of brick scrap from different places of demolition of building structures.

This article describes the relevance of geodetic control. Briefly describes the existing and proposed methods of geodetic control. Also the special device for geodetic researches of industrial buildings and constructions is offered. This device is attached to the geodetic rail, it is fixed laser rangefinder. With this device it is possible to perform geodetic survey of building structures of an industrial building or structure without fixing reference points. The technical task of the claimed device is the joint use (fixation) of the standard laser rangefinder and geodetic rack due to the constructive execution of the device, in the production of geodetic works to determine the deflections of supporting structures of industrial, public and residential buildings. For verification of the claimed device was carried out surveying work for determining deflections of the roof trusses of an industrial enterprise. Conclusion: labor costs of geodetic works were reduced in comparison with traditional methods by an average of 20 – 30%.
