CONSTRUCTION RESEARCH
Field data is useful only when context travels with the number.
Construction productivity data can mislead when scope, crew composition, conditions, and exceptions are removed.
Minimum context
Record project type, task definition, location context, date, shift length, crew size, equipment, material conditions, and responsible reviewer.
Production units
Define the measured unit, included work, excluded work, quality threshold, rework treatment, and start/stop rules.
Delay classification
Separate weather, access, material, equipment, inspection, design, safety, and owner-caused delays instead of combining all lost time.
Privacy and labor safeguards
Do not use productivity records to make unsupported individual-performance judgments. Limit personal data and document access controls.
Benchmark limitations
A benchmark should show sample size, project types, range, exclusions, and why the result may not transfer to a different site.
