The company "GCE – North" provides the technical diagnostics of buildings or as it is called an engineering inspection of buildings, technical expertise of buildings, building inspection facilities, technical inspection of construction of buildings and constructions, or just survey. "GCE-North" has the necessary license for this, staff expertise and instrumental measurement laboratories. Unlike many countries in Russia and the CIS technical diagnostics of buildings, as well as diagnostics of technical devices at hazardous production facilities is compulsory and is fixed Federal law 116 "On industrial safety of dangerous industrial objects in Russia" 1997. Technical diagnostics of buildings (structures) is carried out to identify the actual technical condition of building structures, determining the actual bearing capacity of structural elements, with the acting loads and full-scale survey data (assessment of residual life). The work of experts is to develop technical solutions to address identified in the survey defects and damages, as well as making recommendations on further exploitation of the object. The basis for the technical inspection of buildings (Structures) may be the following reasons: the detection of defects and damage under periodic inspections and special, and increase operational loads and actions on structures in redevelopment, upgrading and increasing the number of storeys of the building, reconstruction of buildings or structures and to identify deviations from the project, reducing the carrying capacity and performance of structures, lack of project design and the executive documentation, change the functional purpose of buildings and structures; resuming construction of buildings and structures in the absence of conservation or the expiration of three years after the cessation of construction in implementation of measures for conservation; strain soil foundation, the need to monitor and evaluate the technical state of the structures of the buildings located near the newly built facilities, the need to assess of building structures exposed to fire, natural phenomena, action, loads of natural-climatic or man-made, prescription of supervisors, the need for conclusions about the state of buildings and structures for the organization of a license to operate plants and facilities; expiration of a survey or legal terms of operation, the change of ownership, insurance organization, the definition of economic feasibility of repair or reconstruction. The volume, composition and nature of diagnostics depend on the type and characteristics of the object, and set specific targets.
