ICUQF specifies data pipelines that connect IoT sensing, edge processing, cloud storage, and Common …

Integrated Construction Risk Assessment Framework, Felix Delmonte

Mechanical and Civil Engineering Faculty Publications

An integrated risk assessment architecture for construction projects synthesizes data governance, BIM, Digital Twins, and hybrid analytics into a continuous feedback loop that links sensing, semantic modelling, probabilistic simulation, and organizational learning. The framework distinguishes aleatory from cognitive uncertainty and prescribes layered methods: Monte Carlo and Bayesian updating for measurable variability; fuzzy inference and consensus aggregation for linguistic and expert judgements; and graph-based discovery for dynamic cyber-physical topologies represented as time-varying graphs 𝐺𝑡. Governance primitives, aligned with ISO 19650, enforce provenance, interoperability, and staged readiness thresholds that prevent premature prescriptive outputs until model convergence criteria are met. BIM and GIS …

Building Resilient And Sustainable Built Environments Through Climate Adaptation, Digital Innovation, And Infrastructure Governance, Mohammed Ali Berawi, Mustika Sari, Perdana Miraj

CSID Journal of Infrastructure Development

The built environment has become one of the most important arenas for responding to climate change, resource pressure, and rapid urban transformation. Cities, infrastructure networks, buildings, and construction projects are no longer expected only to provide physical services. They are also expected to reduce environmental impact, protect communities from disruption, support economic activity, and remain useful under uncertain future conditions. This expectation places resilience and sustainability at the center of infrastructure development.

Resilience refers to the capacity of built systems to anticipate shocks, absorb pressure, recover from damage, and continue functioning. Sustainability asks whether those systems can do so while …

A Machine-Learning-Based Systematic Framework For Modeling Compression And Recompression Indices For Florida Soils, Michael Morales

Doctoral Dissertations and Master's Theses

This thesis develops a machine-learning framework for estimating the compression index and the recompression index of Florida soils from routinely measured index properties, and reports two studies that build it. Consolidation settlement design requires both indices, and both are obtained from the incremental-loading oedometer test, which occupies a specimen for one to two weeks; the index tests that accompany it are complete within hours. Empirical correlations have filled that interval since the 1950s, but their coefficients are calibrated on specific soil populations and transfer poorly between regions. The first study analyzes 376 consolidation tests compiled for the Florida Department of …
