1.5.Weather Delays. TIME EXTENSIONS FOR UNUSUALLY SEVERE WEATHER

(OCT 1989) (ER 415-1-15)

1.5.1. 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 satisfied:

a. 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.

b. 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.

1.5.2. 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

4 4 4 5 5 4 4 4 4 3 4 4

1.5.3. Upon acknowledgment of the Notice to Proceed (NTP) and continuing throughout the contract, the contractor will record on the daily Contractor Quality Control (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 50 percent of more of the contractor’s scheduled work day. 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 1.10.2, above, the contracting officer will convert any qualifying delays to calendar days, giving full consideration for equivalent fair weather work day, and issue a modification in accordance with the contract clause entitled “Default (Fixed Price Construction)”.

The subbase shall be compacted in 6 inch lifts to achieve desired grade. The aggregate base shall be a minimum of 6 inches thick and compacted as specified. The concrete parking area shall be a minimum of 6 inches thick with thickened edges. A drawing of the parking area in relationship to the bathroom and access roadway is attached.

3. The contractor shall place a concrete stairway to access the restroom sidewalk from the parking area. The stairway shall be 4 feet wide and have handrails on each side that meet ADA standards. The length of the stairway will be dependent on the 4 to 1 slope specifications for fill around restroom and the elevation difference between the restroom sidewalk and the parking lot.

b. Concrete Reinforcement.

Concrete shall be reinforced with #3 rebar for the sidewalks and stairway and #4 rebar for the parking area. Rebar shall be placed on 18” centers longitudinally and transversely. Dowels shall be placed in the concrete foundation of the CXT restroom to prevent heaving or settling of the sidewalks. Rebar ends shall overlap a minimum of 6” and be wired securely together. Fabricate and place concrete reinforcing in accordance with ACI 318.

c. Cast in Place Concrete.

The contractor shall provide 3500-PSI concrete. Delivery tickets shall be furnished with each delivery and a copy made available to the government inspector. The contractor shall saw the sidewalks and parking area to allow for expansion cracks.

d. Concrete Finishing.

Concrete shall be finished in a matter to provide a smooth surface in accordance with ACI 301. The concrete shall be placed and finished so as to provide a surface that is free of defects such as low places (Bird baths) or high ridges, etc. The finish surface shall be tested for straightness. The maximum allowable deviation shall be ¼ inch in five feet. The surface of the concrete shall receive the equivalent of a steel trowel finish, but while still sufficiently wet to be worked; the surface of the concrete shall be lightly broom finished.

e. Curing and Protection.

All concrete shall be cured by approved method for three days. During the curing period the concrete shall be protected from physical damage.

f. Form Removal.

Forms may be removed after 24 hours and must be accomplished in a matter that prevents damage to the concrete.

The wheel stops shall be centered in the parking spots and be 12 inches from the end of the parking spot.

The contractor shall stripe the parking lot to delineate each parking space. The handicap parking space shall be indicated with a handicap emblem and have diagonal striping on each side. The parking lot will have 7 parking spots including the handicap parking spot.

3.1.11 Landscaping and cleanup After all construction work has been completed, the contractor shall place and grade top soil free of all foreign debris a minimum of 4 inches thick to match the elevation of the sidewalks, parking area, and undisturbed surrounding grounds. All exposed top soil shall be sodded with Bermuda grass sod. The contractor shall water the sod for a minimum of one hour per day for a minimum of 7 days. All foreign debris shall be removed from construction site to complete work.
