LOSS OF PRODUCTIVITY -
“normal working methods”: RESOURCED PROGRAMME, METHOD STATEMENTS, MEASURED MILE ANALYSIS (RECORDS)
“lower efficiency”: EARNED VALUE PRODUCTIVITY ANALYSIS (RECORDS)
DISRUPTION ANALYSIS –
LOSS OF PRODUCTIVITY plus ANALYSIS - alignment of cause and effect, “balance of probability”

21. RESOURCED Programme Public Works Contract:
4.9.1 (4) – “the Contractor’s estimate of each category of Contractor’s Personnel and Contractor’s Things expected to be on Site for each period”
