Data-Driven Quantitative Performance Evaluation of Construction Supervisors has been published in the journal Buildings.

The performances of construction supervisors are essential for the monitoring, control, and coordination of the construction process of a project in order to adhere to a predefined schedule, cost, quality and other factors. However, it is challenging to evaluate their performance due to limitations such as data deficiency, human error, etc. Thus, this paper proposes an approach to data-driven quantitative performance evaluation of construction supervisors by integrating an analytic hierarchy process (AHP) and activity tracking. The proposed approach contains three parts, namely, index extraction, weighting, data-driven index calculation, and then validation by case study. Firstly, performance indexes were developed based on a literature review as well as surveys and function analysis of the information system for construction supervision (CSI system). Then, the weights of and relationships among of the indexes are determined by AHP. After that, with daily workflow and inspection activities tracked in the CSI system, a method and a software module for automatic calculation of indexes were developed. Lastly, the proposed approach was validated by a real-world case. The result showed that the proposed approach can quantify the performance of a construction supervisor systematically and automatically, which shed lights on how to evaluate the performance of a worker based on the tracking of daily activities. The data-driven process enhanced our strong interpretation of member actions and evaluation indexes, and can boost the performance of every member in an organization.

The two papers published by our research group in the Journal of Information Technology in Civil Engineering and Architecture, A BIM-based Facility Intelligent Management System and Web-oriented BIM 3D Viewing and Information Management, were selected as high PCSI papers, high citation papers and high download papers (namely "three high papers") in the Academic Highlights Database of China National Knowledge Network (March-April 2023). This is a great recognition and encouragement for our research work!

A total of 124 papers were selected in the journal of Civil and Architectural Engineering Information Technology, including 70 papers with high PCSI, 95 papers with high citation, 43 papers with high download and 22 papers with "three high".

Note: Papers with high PCSI, papers with high citation frequency and papers with high download frequency respectively represent the top 1% PCSI papers with the same literature type in the same discipline in the same year, the top 1% papers with the total citation frequency and the top 1% papers with the total download frequency. Among them, the paper A BIM-based Facility Intelligent Management System has been downloaded 1376 times and quoted 115 times on CNKI. The paper "Web-oriented BIM 3D Viewing and Information Management" has been downloaded 1521 times and quoted 85 times on CNKI.
