This comprehensive expert survey of the facility was compiled based on the results of a construction and technical assessment of the work actually performed under Contract No. 2022.118108 dated July 25, 2022, against the terms of the contract, design and estimate documentation, and regulatory and technical documentation, including the fire protection project for the metal structures – the building's load-bearing elements. The purpose of the work was to determine: - whether the work actually performed under Contract No. 2022.118108 dated July 25, 2022, complies with the terms of the contract, design and estimate documentation, and regulatory and technical documentation, including the fire protection project for the metal structures – the building's load-bearing elements; - whether there are any defects or damage to the fire protection coating of the load-bearing metal structures (steel frames) in the building of the State Autonomous Institution of Additional Education "School of Olympic Reserve No. 4," located at the following address: Orenburg, st. Komsomolskaya St., 197/3, completed by Stroyservis LLC under contract No. 2022.118108 dated July 25, 2022; - what is the cause of the identified defects and damage to the fire protection coating of the load-bearing metal structures (steel frames) in the building of the State Autonomous Institution of Additional Education "School of Sports School No. 4," located at 197/3 Komsomolskaya St., Orenburg; - was the use of OBEREG-OVM fire-retardant paint and Obereg FlaimGuard mastic, approved in the technical specifications and estimate, sufficient to achieve and operate the results of the work under contract No. 2022.118108 dated July 25, 2022, taking into account the work being carried out and the use of its results in the building of the State Autonomous Institution of Additional Education "School of Olympic Reserve No. 4", located at the address: Orenburg, Komsomolskaya St., Bldg. 197/3 (Ice Palace), or was the use of additional materials required that were not provided for in contract No. 2022.118108 dated July 25, 2022; - what is the cost of eliminating defects and damage. The following conclusions were reached as a result of the completed work: The actual work performed under Contract No. 2022.118108 dated July 25, 2022, contains numerous violations and discrepancies with the terms of the contract, regulatory and technical documentation, and the fire protection design for metal structures – the building's load-bearing elements: - Violation of the coating preparation technology before applying the fire-retardant coating – application of new primer and paint to a metal surface that had not been cleaned of old primer; - Corrosion "through the paint" due to insufficient cleaning of the metal surface before applying the primer; - High content of fire-resistant pigments in the coating composition (the entire layer – mastic and paint – was analyzed) – the spectrum analysis program automatically detected the presence of titanium dioxide in an amount of 85-89% of the total composition, which led to paint peeling; - Inadequate quality of the OBEREG-OMV fire retardant coating applied to metal structures (steel frames) in the building of the State Autonomous Institution of Additional Education "School of Olympic Reserve No. 4," located at 197/3 Komsomolskaya Street, Orenburg; - Paint and primer coating application requirements were not met; the paint is applied in several layers and to a specified thickness of 0.4-0.5 mm; - Multi-stage quality control of the fire retardant coating was not performed; - The coating's warranty period of at least 20 years was not met, subject to compliance with the technological regulations. Based on the expert examination, the following were identified as the main causes of defects and damage to the fire retardant coating on load-bearing metal structures: - Application of new primer and paint to a metal surface that had not been cleaned of the old primer; - Corrosion "through the paint" due to insufficient cleaning of the metal surface before applying the primer; - A high content of fire-retardant pigments in the coating (the entire layer—mastic and paint—was analyzed)—the spectrum analysis program automatically detected the presence of titanium dioxide at a level of 85-89% of the total composition. The fire-retardant coating under study exhibited an imbalance in the organic component to mineral additives ratio, with the latter significantly exceeding the former. This suggests that the use of OBEREG-OVM fire-retardant paint and Obereg FlaimGuard mastic, as approved in the technical specifications and estimate, may have been insufficient to form a fire-retardant layer with good adhesion. Furthermore, significant imperfections in the surface preparation of the metal structures were observed, which clearly led to the observed defects. The market value of the work to eliminate the defects and damage is represented by a local estimate and amounts to 13,316,654.66 (thirteen million, three hundred sixteen thousand, six hundred fifty-four) rubles and 66 kopecks.
