State-of-the-Art Review of Construction Performance Models and Factors
Bibliographic record
Abstract
Measuring and assessing construction project performance on an ongoing basis is an important part of management and control of a project. Described in this paper is the current state-of-the-art of research on prediction and explanation of construction project performance gleaned through an extensive literature search that identified 122 relevant articles published over the last 20 years. This review was carried out in support of an ongoing research program that seeks to embed within a decision support system a transparent reasoning schema that operates on fundamental relationships amongst influencing factors as well as user-defined, experience-based hypotheses for explaining project performance. Findings from the review are presented in two tables that identify performance measures treated (productivity, time, cost, scope, quality, safety, project success and others), level of analysis (overall project, work package, individual activity), and factors that affect performance outcomes. The paper concludes with a discussion of the findings in terms of areas of consensus, knowledge gaps, and steps to be pursued to develop a robust and practical schema for interpreting project data in order to explain the basis for performance to date.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
