Abstract

fetched live from OpenAlex

Data quality and lack of reliable information about changes, claims, and risks are ongoing challenges in construction contract administration (CCA). These issues along with ineffective information management, can result in poor decision-making, and eventually, cost overruns and delays. The CCA processes involve complex communications and management of information flow among stakeholders. Blockchain and ontology have been widely studied for their capabilities to improve collaborative information management and foster decision-making, but their integration potentials are mostly unexplored within the context of CCA information management. This study aims to develop a contract information management system leveraging the benefits of blockchain and ontology. The system is demonstrated using change management as a representative CCA process, with two main objectives: (1) to overcome issues hindering trust and collaboration for the effective management of CCA-related information flow, and (2) to improve accessibility to reliable data for effective decision-making. A decentralized and collaborative contract information management (DCCIM) system was proposed encompassing two main layers of blockchain and ontology-based information management. Additionally, a novel framework was developed for designing the smart contract and blockchain network based on a standardized ontology and business process model. The system was evaluated using a change management process as a case study to demonstrate its applicability within CCA workflows. The blockchain infrastructure enables reliable, collaboratively managed information flow, while the ontology facilitates the development of smart contracts aligned with the management process and enhances access to information by supporting complex queries and automated reasoning over captured data. The proposed DCCIM system could be a promising building block for future developments and full automation of CCA processes.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
