Documentation of the Weather or Other Delaying Events and How They Relate to the Critical Path

In addition to giving the notice a contractor should send documentation that they are entitled to a time extension and extra money due to the delay. For example, the contract may require that the claim shall be documented by data substantiating that weather conditions were abnormal for the period of time, could not have been reasonably anticipated, and had an adverse effect on the scheduled construction. This would include NOAA records showing that rainfall exceeded the norm along with anything else that would show that weather prohibited or affected work. It also could include diaries, notes, letters from subcontractors, pictures showing the condition of job, weather reports, etc.
