DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The Kabetogama (Kab-tog-ga-ma) Lake Visitors Center boat launch ramp is one of the three public use boat launch ramps in the park and one of the main entry points where visitors launch their boats and park during their stay in the park. The reinforced concrete ramp has been in service for 30+ years and has potholes, large cracks and is deteriorated to the point where damage has occurred to boat trailers due to the ramp’s condition. Work is to include removal and reconstruction of the concrete boat ramp. Work will entail working within, or coffering Kabetogama Lake to extent necessary to accomplish the scope of work in this project.

1.2 Work Covered by the Contract Documents:

A. Project Location: Voyageurs National Park , Kabetogama Lake Visitor Center, 9940 Cedar Lane, Kabetogama, Minnesota 56669 (approximately 25 miles east of International Falls, MN)

B. Work consists of: Removal of an existing reinforced concrete boat ramp, measuring approximately 40-feet wide by 105-feet in length with a 6-inch thick profile. The existing ramp has a stone rip-rap surround with an undetermined extent buried within the subsoil around the ramp. Rip rap to be extracted and re-used or allowed to remain in place related to ability to construct the new ramp. Water depth varies seasonally with an average of 8-foot maximum depth at in-water end of ramp.

New construction shall be a 36-foot wide by 105-foot long reinforced concrete ramp of a 7-inch profile and thickened slab perimeter curb walls. New boat ramp shall be placed on 6-inch layer of compacted aggregate base and separated from subsoils by one layer of placed geotextile fabric. New stone rip rap shall be added to any remaining existing rip rap material to provide a stabilized surround to the in-water perimeter of the new ramp.

Preceding existing boat ramp removals and new ramp construction, the Contractor shall provide approved means and methods to cofferdam the active in-water construction area to provide a ‘dry dock’ condition to perform construction. Provision of a weighted turbidity barrier curtain within the water surrounding the construction area will additionally be required.

Site restoration shall be limited to extent of disturbance to turfgrass, sand-soil shoreline, and any construction damage to existing asphalt parking lot to be returned to re-construction condition or better.

C. All work will be performed under a single contract.

PART 3 EXECUTION

3.1 QUALITY ASSURANCE SAMPLES AND TESTS

3.1.1 Quality Assurance Samples

Provide assistance to the Contracting Officer Representative in the collection of quality assurance samples for quality assurance testing; assign 7 days in the schedule to allow for testing. Collect samples upon delivery to the site at the request of the Contracting Officer Representative. . Identify samples with a waterproof marker by manufacturer's name, product identification, lot number, roll number, and machine direction. The date and a unique sample number shall also be noted on the sample. Discard the outer layer of the geotextile roll prior to sampling a roll. Samples shall then be collected by cutting the full-width of the geotextile sheet a minimum of 3 feet long in the machine direction. Rolls which are sampled shall be immediately resealed in their protective covering.

3.1.2 Quality Assurance Tests

Provide quality assurance samples to an Independent Laboratory. Samples will be tested to verify that geotextile meets the requirements specified in Table “REQUIRED FILTER FABRIC PROPERTIES”.

Test method ASTM D4355/D4355M shall not be performed on the collected samples. Geotextile product acceptance shall be based on ASTM D4759. Tests not meeting the specified requirements will result in the rejection of applicable rolls.

3.2 INSTALLATION

3.2.1 Subgrade Preparation

The surface underlying the geotextile shall be smooth and free of ruts or protrusions which could damage the geotextile. Subgrade materials and compaction requirements shall be in accordance with Section 31 20 00 EARTH MOVING.

VOYA – 225133 31 05 19 - 5

3.2.2 Placement

Notify the Contracting Officer Representative a minimum of 24 hours prior to installation of geotextile.

Geotextile rolls which are damaged or contain imperfections shall be repaired or replaced as directed, and per manufacturer’s recommendations. The geotextile shall be laid flat and smooth so that it is in direct contact with the subgrade. The geotextile shall also be free of tensile stresses, folds, and wrinkles.

On slopes steeper than 10 horizontal on 1 vertical, lay the geotextile with the machine direction of the fabric parallel to the slope direction.

3.3 SEAMS

3.3.1 Overlap Seams

Continuously overlap geotextile panels a minimum of 12 inches at all longitudinal and transverse joints. Where seams must be oriented across the slope, lap the upper panel over the lower panel. If approved, sewn seams may be used instead of overlapped seams.

3.3.2 Sewn Seams

Factory and field seams shall be continuously sewn on all slopes steeper than 1 vertical on 4 horizontal The stitch type used shall be a 401 locking chain stitch or as recommended by the manufacturer. For field and factory seams which are sewn, provide at least a 7-foot sample of sewn seam before the geotextile is installed. For seams that are field sewn, the seams shall be sewn using the same equipment and procedures as will be used for the production seams. If seams are sewn in both the machine and cross machine direction, provide samples of seams from both directions. The thread at the end of each seam run shall be tied off to prevent unraveling. Skipped stitches or discontinuities shall be sewn with an extra line of stitching with a minimum of 18 inches of overlap.

3.4 PROTECTION

Protect the geotextile during installation from clogging, tears, and other damage. Damaged geotextile shall be repaired or replaced as directed. Use adequate ballast (e.g. sand bags) to prevent uplift by wind. The geotextile shall not be left uncovered for more than 14 days after installation.

3.5 REPAIRS

Repair torn or damaged geotextile. Clogged areas of geotextile shall be removed. Perform repairs by placing a patch of the same type of geotextile over the damaged area. The patch shall extend a minimum of 12 inches beyond the edge of the damaged area. Patches shall be continuously fastened using approved methods. The machine direction of the patch shall be aligned with the machine direction of the geotextile being repaired. Remove and replace geotextile rolls which cannot be repaired. Repairs shall be performed at no additional cost to the Government

3.6 PENETRATIONS

Construct engineered penetrations of the geotextile by methods recommended by the geotextile manufacturer.

3.7 COVERING

VOYA – 225133 31 05 19 - 6

Do not cover geotextile prior to inspection and approval by the Contracting Officer Representative.

Place cover soil in a manner that prevents soil from entering the geotextile overlap zone, prevents tensile stress from being mobilized in the geotextile, and prevents wrinkles from folding over onto themselves. On side slopes, soil backfill shall be placed from the bottom of the slope upward. Cover soil shall not be dropped onto the geotextile from a height greater than 3 feet. No equipment shall be operated directly on top of the geotextile without approval of the Contracting Officer Representative.

Use equipment with ground pressures less than 7 psi to place the first lift over the geotextile. A minimum of 6 inches of soil shall be maintained between full-scale construction equipment and the geotextile. Cover soil material type, compaction, and testing requirements are described in Section 31 20 00 EARTH MOVING. Equipment placing cover soil shall not stop abruptly, make sharp turns, spin their wheels, or travel at speeds exceeding 5 mph.
