Whether you are building the programme or defending it,
the weather allowance should be measured — never assumed.
MAKE
Build a defensible calendar set
Drop your P6 — it finds your site itself. Or click the map.
Pick the work: Earthworks, Pavements, Structures — each with its own measured delay factors
Set the confidence as a P-value, or type the % time lost your CM already knows
One import-ready .xer with the whole calendar family inside — plus the Basis of Schedule that justifies every blocked day
ANALYSE
Rate the allowance you already carry
Every calendar in your programme, rated against the full rainfall record at your site
A plain verdict: your allowance rates as P8 — conservative, about right, or light
Where your finish date lands under more or less weather
Your own file back with the corrected calendars inside, activities untouched
EVIDENCE
Every blocked day cites its observation
Real gauge records — up to 127 years deep — not gridded estimates, wherever a good station exists
Delay factors measured on real Australian projects, work type by work type
Documents that read like a Basis of Schedule because they are one
No element of the allowance is assumed
