One of the key aspects of working with information models of buildings and structures (TIM models) is filling them with various information. Information about placement levels, fire safety indicators, dimensions and many other characteristics are a significant part of the information model. From the point of view of automating the processing of TIM models, even a minor typo or the presence of invisible characters (for example, extra spaces) can lead to the information model not meeting the requirements of the examination.

On 23 April, 2025, representatives of the Educational Center for Digital Competences (ECDC) of the St Petersburg State University of Architecture and Civil Engineering received a certificate of state registration of the computer program No. 2025660311: "TIMTest - software for validating the attribute content of information models of buildings and structures." Software developers: Yury Zgoda (category II specialist), Inna Sukhanova (Director of the ECDC, Associate Professor) and Denis Nizhegorodtsev (Deputy Director of the ECDC, Senior Lecturer).

TIMTest allows you to describe the requirements for the attribute content of a model (the presence of parameter groups, their information content, the correctness of the data type) in a readable format, and then, in a fully automatic mode, check any TIM model provided in the open IFC format for errors. Such checks can be used for a preliminary assessment of the compliance of the provided model with the requirements of the examination.

Before registration, the developed software demonstrated its high efficiency within the framework of the main stage of the All-Russian TIM-Championship of SPbGASU, which was held from 28 October to 27 November, 2024. The updated version of the program (adjusted in accordance with the innovations of the technical specifications) was used to evaluate the work of TIM coordinators within the framework of the selection stage of the All-Russian TIM-Championship of SPbGASU 2025.

Information modeling opens up many new opportunities for specialists in the architectural and construction industry, but at the same time it creates new requirements for the documentation provided to them (including digital). This development is designed to minimize the number of typical errors in model preparation and thus allow specialists to concentrate on solving other, more creative tasks, entrusting the verification of information content to automation tools.
