This provision specifies the procedure for determination of time extensions for unusually severe weather in accordance with:

a. This provision specifies the procedure for section (d) of the CONTRACT CLAUSE 52.249-10 titled "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 for the duration of the project.

MONTHLY ANTICIPATED ADVERSE WEATHER DELAY WORKDAYS BASED ON (5) DAY WORK

WEEK *

Jan Feb Mar Apr May June Jul Aug Sep Oct Nov Dec Warsaw Mo 65355

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

c. Upon acknowledgment of the Notice to Proceed (NTP) and continuing throughout the duration of the contract, the Contractor shall 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 path activities for 50 percent or more of the Contractor's scheduled workday.

d. Within ten days of the following month, the Contractor shall provide in writing a list of proposed dates of the actual adverse weather delay days for each month. 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 and issue a modification in accordance with the Contract Clause entitled "Default (Fixed Price Construction)". After the original contract completion date has passed, adverse weather that causes delay to the completion of the project will be granted day-for-day without deducting anticipated adverse weather delay days and will be converted from workdays to calendar days.

* Monthly anticipated weather delay days shall be adjusted proportionally if work is scheduled to be performed in a work week with greater than or less than a five-day work week. The following formula shall be used to adjust the monthly anticipated weather delays: Adjusted monthly anticipated weather delays = A multiplied by (B divided by C); where A = The monthly anticipated adverse weather delay for a particular month based on a five-day work week. B = The actual average number of days work is scheduled to be performed in a work week during that particular month. C = The number five (5) e.g., If the monthly anticipated adverse weather delay for January based on a five-day work week is 10 days, but the Contractor actually scheduled an average of a six-day work week for that month, the monthly anticipated weather delay would be adjusted by applying the above formula as follows: 10 x (6/5) = 12 days.

* Monthly anticipated weather delay days shall also be adjusted proportionally for those situations involving a fractional part of a month. Some examples are the month Notice to Proceed is acknowledged and the month of the original contract completion date. The following formula shall be used to adjust the monthly anticipated weather delays:

Adjusted monthly anticipated weather delays = D multiplied by (E divided by F); where

D = The monthly anticipated adverse weather delay for a particular month.

E = The number of calendar days during that fractional part of a particular month.

F = The number of calendar days in that particular month. e.g., The monthly anticipated adverse weather delay for the particular month is 9 days. The original contract completion date is on the twentieth (20th) day of a thirty (30) day month. The monthly anticipated adverse weather delay would be adjusted by applying the above formula as follows: 9 x (20/30) = 6 days.

3 EXECUTION

3.1 Grade Roads and Parking Lots

Grade roads in a manner that eliminates erosion trenches and washouts. When grading roads, a crown in the center of the roadway and sloping away on either side of the centerline is required. The slopes on either side of the centerline shall have a minimum slope of 2% and a maximum slope of 6%. The road shall be uniform throughout the entire road section to be repaired. The road shall be constructed to drain surface water to the side ditches and all ditches shall be kept open by the contractor.

Perform grading on parking lots to remove any erosion trenches or wash outs. All grading shall be sloped according to surrounding topography to provide for positive drainage of no more than 2% prior to applying aggregate.

The Contractor shall ensure final grade allows for proper drainage; ditches and shoulder are shaped; erosion control methods are installed to handle stormwater runoff; all debris is removed such as large rocks or vegetative debris.

3.2 Aggregate Roadway and Parking Lot Surfaces

The contractor shall haul and spread aggregate on roads, parking lots, access trails to ag fields, the quantity and size of rock as specified for each area in the drawings. Aggregate for roadways shall be spread the width of the delivery truck, at a minimum of 8 foot wide and a maximum of 10’ wide. Quantity of material as specified for each site location shall be spread evenly the entire length of roadway (site specific). The Contractor shall adjust thickness depth (up to 2” thick) to accommodate spreading of material the full length of roadway. Aggregate for parking lots shall spread the quantity of material as specified for each site location evenly. The Contractor shall adjust thickness depth to accommodate spreading of material evenly over the entire parking area.

Sub-base for parking lots shall be spread evenly over designated area and compacted. Compaction can be obtained by passing a minimum 8,000-pound machine over area until no more than ½” deflection of soil is obtained or other method that obtains the same result.

Submit copies of waybills or delivery tickets during progress of the work so quantities can be verified for each site area as specified.

3.3 Berm Installation

Berms shall be a minimum of 12’ deep (base width) x 18’ (estimate) roadway width x 6’ height in front of berm forming a peak 1’ wide. Berm shape is trapezoidal, and shape must be consistent through its length. Berm shall be built of material that is identified or approved by the COR from on-site or excess roadway overburden. The fill material may be obtained from behind the berm and not in front of berm (vehicle approach side). Fill material may be collected from the existing roadbed or at a location near the berm agreed upon by the Contracting Officer Representative if necessary or excess spoils from grading operation may be used. Soil compaction by machine rolling or tamping in place in lifts no more than one foot. Compaction can be obtained by passing a minimum 8,000-pound machine over lifts until no more than ½” deflection of soil is obtained or other method that obtains the same result. Note: roadway width may vary on existing roads, however contractor is to build berm from ditch to ditch with variances in widths.

Grass seed with a construction mix of 75% tall fescue and 25% rye grass. Rake in seed in sub-surface and apply a minimum of 6 pounds of seed mixture per berm.

All berms shall have 3 individual red diamond signs placed 5 feet in front of berm on u-channel metal post.

3.4 Sign Installation

Mount 3 individual red diamond signs with post at each berm site. Install at 42” height above ground level on a single u-channel post with bolts. Mounting height is measured from the ground level to the bottom edge (point of sign) of the sign panel. Sign placement must be within the approaching driver’s immediate cone-of-vision.

Placement must be carefully considered to ensure that each sign fits its location and achieves optimum visibility.

Uniformly space the signs across the width of roadway with the middle sign place in center of roadway.

Installation of u-channel post – these are standard signpost and can be driven in ground by a post driver or other suitable method such as boring a hole and concreting in place, so stability is obtained. Embedment depth of u-channel post is a minimum of 2’ 6” however these dimensions could vary based on encounters with underground obstruction such as solid rock. Variance of embedment depth could be allowed with COR approval related to unforeseen circumstances.

3.5 Corrugated Polyethylene Drainage Pipe (Culvert) Replacement

Culvert work will consist of removal and the new installation of a corrugated polyethylene pipe. Installation shall follow manufactures recommendation and submittal of installation procedures submitted prior to placement for approval including fill material.

Upon completion of the installation the road shall be reestablished to pre-construction grade and overlayed with 2” thick of 1” type “B” aggregated surfacing material.

3.6 Tree Limb Removal

Remove encroaching limbs or sprouts on designated roads by cutting or mulcher head machine. Examples include encroaching limbs adjacent to roads, access trails, field edges, and public use area. The contractor shall remove all encroaching tree limbs 5” in diameter or less, from the ground to 16’ above ground. Contractor shall remove limbs within 12’ from centerline of the road. The limb debris may be mulched and spread on shoulder closest to the timber or nearby designated area. A designated area will be provided within one mile by the government at each site area after award. Contractor has the option to remove woody debris off site and dispose of at no additional cost to the government. In no case shall debris be left in roadway or ditches.
