This paper presents the KIB-GW concept, referred to in Polish as Karta Identyfikacyjna Budynku w rejonie Głębokich Wykopów. The proposed framework is an authorial documentation and data-organisation tool developed for structures located in the vicinity of deep excavations. The KIB-GW framework is not a building susceptibility index and does not constitute a control-mode qualification procedure. It does not replace technical inventory, structural assessment, geotechnical design, numerical modelling, field monitoring or expert engineering judgement. Instead, it provides a structured format for collecting, organising and presenting object-level information relevant to excavation-impact assessment. The proposed Building Identification Card may include information concerning object location, spatial relation to the excavation, structural characteristics, foundation system, technical condition, visible defects, photographic documentation, monitoring requirements, predicted or observed ground movements and links to broader assessment procedures. KIB-GW is intended to support consistency in documentation, communication between project participants and preparation of input data for other assessment tools. It may provide object-level information for MKPO-GW/WPO, WNO/STII and MTK-GW. However, the assignment of control modes remains the role of the MTK-GW procedure, while KIB-GW remains a documentation and data-organisation framework. The KIB-GW framework should therefore be clearly distinguished from MTK-GW. KIB-GW answers the practical question: what information is available about a given object and how should it be organised? MTK-GW answers a different question: what technical control mode should be assigned to that object? In this sense, KIB-GW may provide structured input data for MTK-GW, but it does not replace the control-mode assignment procedure. The KIB-GW card may support the organisation of object identification data, location data, construction and foundation information, technical condition records, visible defects, photographic documentation, monitoring assumptions and links to further assessment. The card may also include a data-confidence note indicating whether the available information is preliminary, moderately reliable or sufficiently complete for more detailed engineering interpretation. The proposed framework may be particularly useful in urban and linear infrastructure projects, where numerous buildings, engineering structures, roads, utilities and technical objects may be located near excavation works. In such cases, a repeatable object-level documentation format can improve transparency, comparison between objects and communication between designers, contractors, supervisors and infrastructure stakeholders. KIB-GW may complement broader authorial assessment frameworks. MKPO-GW/WPO supports the multi-criteria assessment of building susceptibility to deep excavation impact. WNO/STII supports the interpretation of settlement-trough morphology and irregularity. MTK-GW supports the assignment of adjacent structures to technical control modes T0–T4. KIB-GW provides the documentation layer in which object-level information is collected and organised for possible use in these procedures. The proposed framework is conceptual and operational in character. It should not be treated as a numerical safety verification method, an automatic classification algorithm or a substitute for detailed technical assessment. The interpretation of the information collected in the card should always consider engineering judgement, available documentation, field observations, monitoring results and project-specific requirements. The original contribution of the KIB-GW concept lies in the structured organisation of object-level documentation for structures adjacent to deep excavations. The framework does not claim originality of general engineering activities such as technical inventory, photographic documentation, monitoring or condition assessment. Its authorial contribution consists in combining these elements into a dedicated Building Identification Card framework linked with deep excavation impact assessment. In this sense, KIB-GW provides a documentation layer between field inventory and broader engineering interpretation. It helps ensure that object-related data are collected in a repeatable, transparent and useful format. KIB-GW Method — Literature and Methodological Context The proposed KIB-GW framework is positioned in relation to engineering practice concerning the protection of structures adjacent to deep excavations. This practice includes technical inventory, photographic documentation, assessment of existing condition, identification of visible defects, monitoring assumptions, distance-based influence zones and interpretation of excavation impact on neighbouring structures. In deep excavation projects, object-level information is often collected from different sources, including field inspection, design documentation, archival records, photographs, monitoring assumptions and communication with project stakeholders. However, these data are not always organised in a consistent format that can be easily used in later assessment, monitoring planning or control-mode qualification. The KIB-GW framework responds to this practical documentation need by proposing a structured Building Identification Card. The card is intended to organise information concerning the object, its location, structural characteristics, foundation system, technical condition, visible damage, monitoring requirements and links to broader assessment procedures. The framework is also related to the assessment of existing structures and excavation-induced ground movements discussed in geotechnical and structural engineering literature. However, KIB-GW does not replace these assessments. Its role is to provide a structured documentation basis supporting further interpretation and decision-making.
