BIM-Enabled Interpretation of Saudi Building Code Shear Wall Requirements for Mixed-Use Buildings

Islam Ibrahim Shoheb , Sonia Ahmed , Haretha Aljabr

Purpose: this study aims to develop a Building Information Modeling (BIM)-enabled methodology that integrates Saudi Building Code (SBC) seismic detailing provisions for reinforced concrete shear walls into a rule-based parametric modeling environment. The research seeks to enhance compliance traceability, automate code interpretation, and improve quantity accuracy for mixed-use high-rise buildings with significant vertical zoning effects. Approach, Selected SBC shear wall provisions were translated into computable IF–THEN engineering rules linked to BIM parameters. The methodology incorporated vertical zoning, axial load ratio evaluation, rule-based reinforcement detailing, and automated quantity extraction. The framework was validated using a large-scale Saudi healthcare mixed-use case study through comparison of BIM-derived quantities with independent SBC-consistent reference calculations on a zone-by-zone basis. Findings, Results indicate that axial load ratio governs boundary element activation and confinement reinforcement demand. BIM-generated reinforcement distributions aligned closely with SBC intent, showing average differences of 2–4% for concrete volume, 3–6% for longitudinal reinforcement, and 4–8% for confinement reinforcement. Boundary confinement was concentrated within the lower 30–40% of building height, while zone-based detailing reduced upper-zone reinforcement by approximately 15–25%. Practical Implications, the methodology improves automated compliance verification, reduces overdesign, enhances reproducibility, and supports efficient structural modeling for complex mixed-use buildings. Originality/Value, the study establishes a direct digital linkage between SBC provisions, parametric BIM modeling, and automated structural quantity outputs.

Quantifying Geospatial Logistics Risks in Construction Supply Chains through an Integrated GIS-4D BIM Framework

Batoul Hasanin , Youssef Aris , Sonia Ahmad , Amarnath CB

Construction supply chains are inherently sensitive to spatial and logistical disruptions, yet conventional project planning approaches including standalone 4D BIM, rarely incorporate geospatial risk factors. This study proposes an integrated GIS-MCDM-4D BIM framework to quantify, simulate, and operationalize geospatial logistics risks within construction supply chains. The framework systematically translates GIS-derived spatial risk indicators such as supplier accessibility, transportation network variability, and route vulnerability into temporal constraints embedded in 4D BIM simulations. A real-world case study of a reinforced concrete project in Syria, involving multiple suppliers and a heterogeneous transportation network, is employed to validate the approach. Findings indicate that even minor spatial disruptions can cascade through interdependent construction activities, resulting in significant schedule delays. The integration of GIS and 4D BIM enables proactive, risk-informed planning, demonstrating that geospatial conditions exert a substantial influence on construction timelines. This framework advances beyond descriptive GIS applications by providing a quantitative, operational tool for enhancing schedule reliability, supplier selection, and decision-making in complex and unstable construction environments. The proposed methodology offers a transferable solution for managing geospatial logistics risks in diverse construction contexts.

Geometry-Driven BIM Element Category Recognition from Open IFC Property Records: A Reproducible Engineering Science Study

Sonia Ahmed , Marek Salamak

Accurate object semantics are essential for building information modeling (BIM) workflows to enable interoperability, model checking, quantity take-off, performance analysis, and other downstream engineering applications. However, in practice, Industry Foundation Classes (IFC)-based model exchanges often feature limited or poorly identified semantic tags, particularly during interoperability with authoring and reviewing tools. This research proposes a re-producible, geometry-based learning algorithm for the automatic recognition of BIM element categories based on publicly available IFC-based property data. The empirical analysis is based on 780 object instances from ten BIM categories from a publicly available sample of IFC object records. A rule based parser translates semi-structured BIM text exports into engineering features as bounding box dimensions, coordinates, elevations and object-status. The study compares three supervised machine-learning baselines via stratified five-fold cross-validation: logistic regression, random forest and extra trees. Random forest performed best overall with an accuracy of 0.992, balanced accuracy of 0.971, a weighted F1-score of 0.992, and a macro F1-score of 0.970. The analysis of feature importance shows that bounding-box height, width, length, spatial coordinates and externality related descriptors are the most important features. The results demon-strate significant semantics can be extracted from minimal engineering descriptors without the need for deep learning of meshes. This work provides an interpretable and efficient baseline for BIM enrichment, assessment, and interoperability-focused preprocessing for engineering science use-cases.

A BIM-Linked Mathematical Decision Model for Energy Retrofit Prioritisation in Existing Building Portfolios

Ashraf Elhendawi , Moustafa Metwally

Building information modelling is increasingly applied to structure engineering information across the life cycle of built assets, but existing buildings are often underconnected to operational data for retrofit prioritisation. This research proposes a BIM-connected retrofit prioritisation model that converts building-performance information into an engineering information layer for initial screening. The method integrates BIM-aligned feature organisation, transparent machine learning, diagnostic validation, and scenario-driven screening to flag buildings for further assessment by engineers. The paper proposes a workflow for institutions and cities seeking to transition from disparate disclosure records to evidence-based retrofit prioritisation without relying on the immediate availability of digital twins. The results suggest that operational, geometric, and typological features can be used to generate interpretable screening markers that help guide engineering judgement, benchmarking, and incremental retrofit strategies. This research offers a replicable model that supplements, rather than substitutes for, in-depth audit and modelling.
