SECTION 00 74 02

TIME EXTENSIONS FOR UNUSUALLY SEVERE WEATHER (NAU)

03/19

PART 1 GENERAL

1.1 DETERMINATION OF UNUSUALLY SEVERE WEATHER

This specification prescribes the procedures to be used on this contract for determination of time extensions for "unusually severe weather" in accordance with the contract clause 52.249-10 "Default: (Fixed Price Construction)".

In order for the Contracting Officer to award a time extension for "unusually severe weather" under this clause, all of the following conditions must be satisfied:

a. The weather experienced at the project site during the contract period must exceed the weather which could reasonably be anticipated based on a minimum of 25 years of historical weather data.

b. The weather must actually cause a delay to the completion of the project or any specified contractual milestone beyond that which would reasonably be anticipated based on the contractors means and methods.

The delay must result from events which are beyond the control and without the fault or negligence of the Contractor.

c. The delay must occur during the contractual performance period.

1.2 MINIMIZING WEATHER IMPACTS

The contractor is responsible for identifying and implementing the means and methods to minimize the overall impact of weather during the contract period.

The means and methods and sequencing of work will impact the extent to which the work is sensitive to or may be impacted by the weather.

Separate payment will not be made for any costs associated with mitigating the impacts of weather.

1.3 INCORPORATION IN PROJECT SCHEDULE

The Contractor's progress schedule must reflect reasonably anticipatable weather in weather dependent activities. The Contractor shall be solely responsible for identifying anticipated weather days based on the activities scheduled during a given time period and the means and methods of executing the work.

Refer to Section 01 32 01 PROJECT SCHEDULE (NAU) for the procedures for incorporating these weather days into the schedule.

1.4 WEATHER CONDITIONS AT THE PROJECT SITE(S)

The Government makes no representation of the actual weather conditions to be expected at the site. No inference or conclusion shall be made

DOCUMENT 00 74 02 Page 2 regarding the actual weather conditions or the actual amount of weather delays based on any information included in the contract documents.

The Contractor shall, prior to submitting a proposal or offer, be solely responsible for determining the actual weather conditions prevalent at the project site or sites and accounting for this information in their proposal or offer.

PART 3 EXECUTION

3.1 REPORTING

Upon acknowledgment of the Notice to Proceed (NTP) and continuing throughout the contract performance period, the contractor will record on the CQC report the occurrence of weather and resultant impact to normally scheduled work. Impacted activities shall be identified by name and activity id on the CQC report.

When the use of RMS-CM (Section 01 45 01 RESIDENT MANAGEMENT SYSTEM - CONTRACTOR MODE) is required by the contract, weather shall be reported on the QC Report in RMS-CM and tracked therein.

3.2 OCCURRENCE OF ACTUAL DELAY

To be considered a day of actual weather delay, progress on critical path activities must be less than 50 percent of the progress scheduled to occur on that day, and the progress must be impacted due solely to the weather.

The delay must be recorded in accordance with paragraph 3.1: failure to provide this information at the time of the preparation of the CQC report will be considered an acknowledgement that no delay existed, however reporting on the CQC report will not automatically be considered concurrence by the Government that delay occurred and it was due solely to the weather.

Failure to make adequate preparations for weather or to adequately protect the work from reasonably anticipatable weather will not be considered an impact due solely to weather.

3.3 CALCULATION OF DELAY AND CONVERSION TO CALENDAR DAYS

Any adjustment in the contract period of performance resulting from unusually severe weather will be based upon the weather over a minimum period of six months.

The contractor shall be solely responsible for providing documentation to substantiate that the actual weather was "unusually severe" based on a minimum of 25 years of historical weather data, the critical path was impacted as a result, and the actual impact to the critical path could not have been prevented through reasonably prudent measures.

As part of this documentation, the contractor must substantiate the reasonableness of anticipated weather days included in the schedule as discussed in paragraph 1.3 INCORPORATION IN PROJECT SCHEDULE. Failure to substantiate the reasonableness of the anticipated weather days may result

DOCUMENT 00 74 02 Page 3 in a determination that the contractor failed to adequately plan and execute the work in a manner consistent with the requirements of the contract, making the delay within their control.

Additionally, the contractor shall provide a detailed listing of all weather days occurring from the Notice to Proceed through the date of the request and show a cumulative net impact to the performance period exceeding that which could be anticipated based on the aforementioned 25 years of historical weather data.

Any calculation performed within RMS-CM under the "Weather Delays" screens of the QA/QC Module shall not serve as the basis for determining the amount of adjustment required.

3.4 ISSUANCE OF MODIFICATION

If the contractor can substantiate an impact to the completion date of the project based on actual "unusually severe" weather as described herein, 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 52.249-10 entitled "Default (Fixed Price Construction)".

3.5 DELAYS OUTSIDE STANDARD WORK DAYS

Weather delays occurring prior to Notice to Proceed, during non-working days, and after the required completion date are not excusable under the Defaults clause.

When the contract performance period, or any extension thereof, has passed, no extensions for unusually severe weather will be granted. This applies as well to any interim milestone or completion date.
