1.29 TIME EXTENSIONS FOR UNUSUALLY SEVERE WEATHER

a. Provision ER 415-1-15 specifies the procedure 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 under this clause, the following conditions to occur:

(1) The weather experienced at the project site during the Contract period to be found unusually severe, that is, more severe than the adverse weather anticipated for the project location during any given month.

(2) The unusually severe weather to actually cause a delay to the completion of the project. The delay is 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 constitutes the base line for monthly weather time evaluations. Include in the progress schedule to reflect these anticipated adverse weather delays in all weather dependent activities.

MONTHLY ANTICIPATED ADVERSE WEATHER DELAY

WORK DAYS BASED ON (7) DAY WORK WEEK

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

(31) (28) (26) (12) (08) (07) (06) (06) (05) (10) (19) (31)

c. Upon mobilization and continuing throughout the Contract, record on the daily Contractor's quality control report, the occurrence of adverse weather and resultant impact to normally scheduled work. Actual adverse weather delay days that prevent work on critical activities for 50 percent or more of the Contractor's scheduled work day. The number of actual adverse weather delay days to include days impacted by actual adverse weather (even if adverse weather occurred in the 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 delay days exceeds the number of days anticipated in list item (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 52.249-10 DEFAULT (FIXED-PRICE

CONSTRUCTION).

d. The navigation restriction period and closure period are excluded from this provision. This period (6 July 2020 - 24 October 2020) will not be extended for unusually severe weather.

If the Contractor chooses not to use Government power, then all utility requirements for construction activities associated with the Contract requirements to be provided by the Contractor. The Government does not guarantee the reliability of incoming power and distribution to the site, and may not be held liable for power outages affecting Contractor operations, or schedule, or both. Make provisions for supplying backup power to maintain construction activities and schedule in the case of a power outage, as necessary.

b. Be responsible for damage caused to Government facilities, receptacles, breakers, and other electrical equipment by damage from Contractor's use and/or operations.

At no additional cost to the Government, and in a workmanlike manner satisfactory to the Contracting Officer, install and maintain all necessary connections and distribution lines. Before final acceptance of the work by the Government, remove all the temporary connections, distribution lines, and associated equipment.

(2) The Contractor may pay the site utility costs above the average monthly costs for each month, while the Contractor is performing work. The determination on when costs start/end is based on when the Contractor is actively using electrical power on-site, as agreed to by the Contractor and the Contracting Officer, but at a minimum when significant Contractor activities are occurring such as coring/sawing/pumping or when three or more Contractor personnel are on-site and using electrical power. If the Contractor is not actively working at the site for an entire month, the utility cost above the amount listed below will be prorated and pay their portion of utility usage.

d. Submit verification of payment to the utility company prior to acceptance of progress payments. Failure to demonstrate payment will result in a retainage held in accordance with Contract Clause 52.232-5
