The following have been modified:

TIME EXTENSION

52.236-4020 TIME EXTENSIONS FOR UNUSUALLY SEVERE WEATHER (31 OCT 89)

(ER 415-1-15)

a. This provision specifies the procedure for the determination of time extensions for unusually severe weather I accordance with the CONTRACT CLAUSE entitled “DEFAULT (FIXED-PRICE CONSTRUCTION).” In order for the Contracting Officer to award a time extension under this clause, the following conditions must be satisfied: (1) The weather experienced at the project site during the contract period must be found to be unusually severe, that is, more severe than the adverse weather anticipated for the project location during any given month. (2) The unusually severe weather must actually cause a delay to the completion of the project. The delay must be beyond the control and without the fault or negligence of the contractor.

b. The following schedule of monthly anticipated adverse weather delays is based on National Oceanic and Atmospheric Administration (NOAA) or similar data for the project location and will constitute the base line for monthly weather time evaluations. The contractor’s progress schedule must reflect these anticipated adverse weather delays in all weather dependent activities.

MONTHLY ANTICIPATED ADVERSE WEATHER DELAY

WORK DAYS BASED ON (7) DAY WORK WEEK FOR LAKE SUPERIOR

JAN FEB MAR APR MAY JUN

31 29 31 20 5 5

JUL AUG SEP OCT NOV DEC

5 5 6 8 30 31

c. Upon acknowledgement of the Notice to Proceed (NTP) and continuing throughout the contract, the Contractor will record on the daily CQC Report, the occurrence of adverse weather and resultant impact to normally scheduled work. Actual adverse weather delay days must prevent work on critical activities for fifty percent (50%) or more of the contractor’s scheduled workday. The number of actual adverse weather delay days shall include days impacted by actual adverse weather (even if adverse weather occurred in previous month), be calculated chronologically from the first to the last day of each month, and be recorded as full days. If the number of actual adverse weather days exceeds the number of days anticipated in Subparagraph (b) above, the Contracting Officer will convert any qualifying delays to calendar days, giving full consideration for equivalent fair weather work days, and issue a modification in accordance with the CONTRACT CLAUSE entitled

“DEFAULT (FIXED PRICE CONSTRUCTION)”.
