ER 415-1-15 dtd 31 OCT 89

(a) This provision specifies the procedure for determination of time extensions for unusually severe weather in 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 found to be satisfied in the sole discretion of the Contracting Officer:

(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.

SECTION 01 10 00.10 38 Page 3

(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 (5) DAY WORK WEEK

JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC

7 6 7 5 6 7 10 9 7 4 8 9

Actual adverse weather delay days must prevent work on critical activities for 50 percent or more of the Contractor's scheduled work day.

(d) 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 delay days exceeds the number of days anticipated in paragraph (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)".

(End of Clause)

1.5 PERFORMANCE AND PAYMENT BONDS

Payment to the Contractor therefore, shall not exceed the bid price and shall be made in accordance with the Contract Clause entitled "PAYMENTS UNDER FIXED-PRICE CONSTRUCTION CONTRACTS." Any additional amount bid in excess of the actual bond premium will be included in the final pay estimate for this contract.

(End of Clause)

1.6 WATER CONSERVATION

Water is one of our valuable natural resources. Accordingly, the Contractor shall be judicious in its use in the performance of the work as specified. Water needed for compaction of roadway and/or foundation materials, and dust control shall be obtained from uncontrolled stream flow instead of potable supply sources to the extent available and suitable as determined by the Contracting Officer or his/her designated representative.
