The given work is devoted to the development and validation of a methodology for multi-variant construction site layout formation using BIM and parametric tools. The research focuses on constrained urban construction sites where crane placement, storage areas, temporary facilities, access routes and safety zones have to be coordinated within limited site boundaries. The following goals are set in the research: 1. analysis of regulatory requirements and scientific approaches to construction site layout planning; 2. formalization of source data, decision variables and active spatial constraints; 3. development of a feasible-space methodology for generation, filtering and diagnostics of layout alternatives; 4. evaluation of feasible variants using engineering and technical-economic indicators; 5. validation of the methodology on real POS-stage source data in a Rhino/Grasshopper prototype. The validation was performed using POS-stage documentation for the SIZO-1 regime building in Arkhangelsk. The source construction general plan was reconstructed as geometric layers and used to test crane-base candidate generation, storage placement, material-route reconstruction, Pareto-style shortlisting and robustness assessment. The study resulted in a traceable decision workflow for site-layout optimization. The model generated 2756 raw crane-base candidate points, of which 61 remained feasible after hard filtering. Five crane/storage alternatives were compared with the baseline POS layout. The selected alternative V3 reduced the material route length from 62.49 m to 34.83 m, which corresponds to a 44.26% route-length reduction and a 96.80 m2 reduction in route-corridor area. Robustness testing showed that V3 passed 9 of 12 scenarios, with a scenario survival ratio of 0.750.
