<p>DOCC — Documentation and Object Context Compilation within IAS-DX is the documentation and input-data module of the integrated IAS-DX framework. The method consolidates and reorganises the earlier KIB-GW, MDO-GW and MDO-GW 2.0/RPSO-GW documentation line under a unified English naming standard.</p>
<p>DOCC provides a structured and traceable basis for collecting, organising and qualifying object-level, excavation-related, geotechnical, monitoring, dynamic and scan-based information for objects located in the influence zone of deep excavation works. It defines the object record, object domain, excavation context, ground and geotechnical context, structural and foundation data, technical-condition information, defect records, photographic documentation, monitoring data, warning flags, data-completeness classes and reliability descriptors.</p>
<p>Within the IAS-DX architecture, DOCC acts as the input-data and documentation layer for the remaining assessment modules. It prepares terrain-side input for SETTLE, object-side input for OSCAR, and control-mode input for MATCH. The module also organises dedicated data packages for IDYN, related to dynamic and vibration-relevant information, and ISCAN, related to scanning, 3D geometry, point-cloud evidence, tilt, displacement, residuals and spatial deformation indicators.</p>
<p>The methodological relationship is expressed as:</p>
<p>IAS-DX = DOCC + SETTLE + OSCAR + MATCH</p>
<p>The current DOCC version transforms the earlier object documentation card and documentation module into a complete IAS-DX input structure. It preserves the practical documentation logic of KIB-GW and MDO-GW, incorporates the extended object-context and predicted-response elements from MDO-GW 2.0/RPSO-GW, and reorganises them into a canonical data-compilation module supporting settlement-trough interpretation, object susceptibility and response assessment, and mechanism-matched technical control.</p>
<p>The document defines methodological lineage, object categories, documentation levels, documentation stages, object-domain notation, mandatory and supplementary data groups, data-completeness and reliability classes, warning flags, IDYN and ISCAN input packages, transfer of DOCC outputs to SETTLE, OSCAR and MATCH, and a reporting checklist for use within the integrated IAS-DX workflow.</p>

<p>MDO-GW Method</p>
<p>This paper presents MDO-GW 2.0, an extended object documentation and forecasting framework for structures and technical objects located near deep excavations. The method develops the original MDO-GW documentation module by integrating RPSO-GW, a predicted object-condition deterioration equation based on the interaction between a documented object and a settlement trough. The framework links object identification, spatial relation to the excavation, structural and foundation characteristics, technical condition, defects, photographic documentation and monitoring assumptions with a parametric description of excavation-induced settlement.</p>
<p>The proposed RPSO-GW module describes the settlement trough by relative width, settlement amplitude and settlement-area potential. The trough is then projected onto the position and effective length of the assessed object. On this basis, mean object settlement, differential settlement and angular distortion are calculated and combined into a predicted object-condition deterioration indicator. In this form, MDO-GW 2.0 transforms object documentation into a documentation-and-forecasting tool supporting technical inventory, monitoring planning, prioritisation of adjacent objects and engineering communication in deep-excavation projects.MDO-GW Method — References<br>[1] Kotlicki, W., Łukasik, S., Godlewski, T., Bogusz, W.
