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. 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.
