Record site facts, quantities, and changes so they can be checked
A useful site report makes the work understandable to someone who was not present. Record the relevant date, location, activity, personnel or equipment information, conditions, progress, interruptions, inspections, and instructions according to the project's requirements. Separate what was observed from an explanation that remains uncertain. “Work stopped while clarification was requested” is different from an unsupported accusation about who caused the delay. Accurate contemporaneous records are more reliable than a reconstructed narrative designed to justify a preferred result.
Measurement needs a defined basis. State the item, location, units, dimensions, method, and relevant drawing or measurement rule. A geometric volume is not automatically the same as a payable contractual quantity. Openings, allowances, overlaps, material changes, or special measurement provisions may affect the contract result. Use the governing basis rather than assuming that a calculation from another project applies. If an exercise supplies simplified rules, keep them identified as assumptions for that exercise.
Trace material and document flow. A delivery note can show what arrived, but it does not by itself prove correct installation, final acceptance, or payment entitlement. Link relevant records to the actual item and work area. A revised instruction should be identifiable by issuer, date, scope, and applicable approval process. Do not change an old report without preserving the appropriate correction trail. An unexplained overwritten value can make later review difficult even when the corrected figure is accurate.
For a change or disruption, preserve the facts needed to evaluate its effect: what differed, when it became known, which activity was affected, what instruction was sought, and what action followed. Recording an event is not the same as deciding every contractual claim or legal consequence. Escalate through the authorized process and avoid inventing a universal Swiss deadline or compensation rule. These original exercises teach evidence, measurement, and traceability for the Baupolier subject area, with real contract and administrative requirements determined by the actual project.
