It is in the preliminary design phase of a project that the designer makes decisions concerning the global geometry of the structure. When working with space frames, the choice of the frame topology is key for the structural behavior. It is difficult to find manuals that provide guidance on which of the most common topologies is the right one for the project, let alone in wood construction. In response to this shortcoming, the use of parametric software is proposed (Grasshopper build1.0.0007 and Karamba 3D 2.2.0.16-220828). The aim is to create a dynamic catalog that responds instantaneously to changes in the parameters to provide information on structural behavior, pre-dimensioning and metrics. With the display of all this information, the architect will have enough technical argumentation to choose or reject options. The proposal is developed through a case study: the early design and analysis stages of flat double-layer timber spatial frames as for rectangular medium-span roofs.

This paper presents the methodology developed in the repair of three oak beam ends in a protected heritage building: the Zabala Palace in Ordizia (Basque Country, Spain). It describes the structural assessment, design, calculation and execution process, as well as the experimental tests carried out in the laboratory to verify and validate the structural capacity of the repair method. The intervention consisted of cutting and removing the beam ends degraded by fungi and replacing them with wooden prostheses. These elements were connected to the beams by means of threaded steel rods and epoxy resin. Calculations based on standards and the literature were verified by laboratory tests where aspects such as the fluidity, filling and pull-out resistance of four commercial epoxy resins were tested. Once the epoxy resin was selected, three samples of the reinforcement design were also flexure tested. The results of the different tests show capacities much higher than those resulting from the application of the calculation procedures in the current bibliography and standards. The implemented solution allowed the conservation of most of the original patrimonial timber, following the criteria of minimum intervention.

The documentation and condition assessment of residential built heritage are often hindered by fragmented records, limited object–data traceability, and weak interoperability between modelling, inspection, database, and analytical environments. This study develops and functionally evaluates an interoperable HBIM-based workflow for constructive characterization and condition-data management. The workflow integrates ARCHICAD, IFC exchange, BIMvision, the BimOndare plug-in, SQLite, and Power BI. It was tested through a pilot demonstrator based on a real multi-storey residential building in San Sebastián, Spain, whose structural configurations and material assignments were deliberately extended to represent reinforced-concrete, steel, timber, and masonry systems. The IFC GlobalId served as the relational key between modelled components and externally stored records. The demonstrator comprised 1281 IFC elements, 183 inspection records, and 354 photographs. Object–data correspondence was additionally verified on 12 structural components with multiple associated records. The implementation demonstrated functional interoperability across the tested environments and supported component-level consultation and building-level filtering by element type, material, location, inspection information, and intervention-related attributes. The study demonstrates the technical feasibility of the proposed information architecture, while longitudinal persistence, model versioning, full-building diagnostic interpretation, usability, and comparative performance require further validation.
