Specifications:

The Contractor shall provide the following:

1. Equipment - Motor Grader with Operator.

· Work schedule shall be amended if wet conditions inhibit quality work. All mileage must be verified by the Contractor by notification to LDWF within 72 hours of grading.

3. Perform “emergency” surface blading as needed/requested by LDWF at the cost per mile rate specified in Attachment C. Response required within 5 working days. “Emergency” designation will be used to address unforeseen needs created by weather events or high use. Could involve work on roads or trails not designated in Attachment D.

Grading Specifications

1. Blade and shape aggregate surfaced roads, trails, and parking areas with a motor grader to produce a surface which is uniform, consistent to grade, and crowned or cross sloped as indicated by the character of the existing surface, but no less than ½” per 1’ of width, and no more than ¾” per 1’ of width.

2. Thoroughly loosen surfacing material to no less than 2” depth or the depth of potholes or corrugations. Scarification to facilitate cutting to the full depth of potholes or corrugations will be considered incidental to blading. Do not scarify to a depth that will compromise the road bed.

3. Shape existing aggregate surfaced drainage dips to divert surface runoff to existing outlet devices, ditches, or discharge locations.

4. Establish a blading pattern which provides a uniform driving surface, retains the surfacing on the roadbed, and provides a thorough mixing of the materials within the finished surface width. Upon final blading, no disturbed rock shall protrude more than 2” above the adjacent surface unless otherwise specified. Remove and place outside of the roadbed, material not meeting this dimension so as not to obstruct drainage ways or structures.

5. Do not allow materials resulting from work to remain on or in structures, such as bridges, culverts, or drainage dips.

General Terms and Conditions:

1. Prices should be proposed on a per mile basis.

2. Invoices will be accepted monthly or following a single, complete grading of all designated roads.

3. Emergency grading price will be used to address unforeseen events or undesignated roads.

4. Mobilization shall be considered incidental for normal grading.

5. Charge for mobilization allowed for emergency grading. One amount should cover mobilization and demobilization per request for emergency grading.
