Construction Specification Fort Randall Chalk Rock Link Trail Construction

1.0 Scope of Work. The Fort Randall project is constructing a natural surface trail link within the Lisa M. Durham Memorial Trail system. The trail link is required to follow standard sustainable trail building practices as defined by the Professional Trail Builders Association (PTBA) including rolling contour alignment, grade reversals, outsloped tread, and armored drainage crossings using natural/locally sourced stone that the contractor sources within the trail site location. Contractor will be required to clear and grub a trail corridor that is a minimum of 72-inches wide and 80-inches high within the designated path alignment. This work consists of clearing, grubbing, trimming, removing, and treating trees, logs, limbs, branches, brush, plants, and other vegetation within the clearing limits. Clearing practices must include removal down to ground level of any cedar tree that will be trimmed 25% or more.

Furthermore, the contractor shall work to avoid any damage to existing, native Burr Oak trees. Cleared vegetation must be removed and piled near the staging area adjacent to the asphalt road for future USACE removal. The trail link will be approximately 2,250 linear feet of bench excavation and tread shaping to establish a stable tread base which follows the alignment in attached Drawing 1, which will be staked by USACE prior to mobilization. The finished trail tread width will range between 36 – 48-inches depending on location and terrain and will be topped with a 4-inch lift of crushed gravel, as measured after completion of mechanical compaction. The crushed gravel will be placed, graded, and mechanically compacted. Mechanical compaction shall be via vibratory plate packer, vibratory roller, or another form of vibratory mechanical compaction achieved via specialized equipment attachment(s). Due to the terrain, the final path at minimum will consist of switchbacks with turning platforms that have a minimum of a 10-foot turning radius to ensure a proper turn radii for both foot and bicycle traffic. The required grade average for the trail tread is 6-8% sustained with a max of 10-15% for no more than 30-foot intervals.

Grade reversals and drainage features are required to be installed as preventative measures to promote long-term sustainability. At the halfway point of the trail link, a 4-foot by 8-foot gravel pad with a 4-inch mechanically compacted lift will be constructed adjacent to the trail path for future USACE placement of a cedar log bench.

Ground disturbance outside of the clearing limits must be prevented. Significant ground disturbance outside of these limits will result in the contractor’s need to perform remedial vegetation measures, as directed by USACE.

3.0.1.8 Quality Control Designation Letter

Prior to mobilization, the Contractor shall submit all items listed above. Each submittal shall include a completed and signed Form 4025 for each submission. In addition to the listed submittals, the Contracting Officer may request submittals for items in the specifications or items shown on the drawings when deemed necessary to adequately describe the work covered in the specifications and drawings. The Contractor shall be responsible for certifying that all submittals comply with the contract requirements. The Contractor shall allow the Government 15 calendar days, beginning from date of receipt by the Government, to review all submittals. The contractor shall consider the review period when providing submittals and possible resubmittals to allow for sufficient time for review and approval by the Government prior to mobilization.

Contractor shall submit a Trail Path Design and Field Layout for Government review. This document shall:

• Provide a PDF drawing of the proposed trail route, including location of drainage crossings and any other non-typical trail features

• State the contractor’s acknowledgement of full intent to follow the Government-staked alignment including all legs and switchbacks shown on Drawing 1 or propose variations which are then clearly indicated on the attached PDF drawing and provided with corresponding justification.

• Define each step in the process and the heavy equipment proposed (Make & Model) for use in the clearing/grubbing process

• Define each step in the process and the heavy equipment proposed (Make & Model) for use in gravel placement and compaction

This submittal will be used by both the Government and the contractor to identify and remedy sources of disagreement before the contractor mobilizes on site. This submittal may require the contractor to perform a site visit prior to mobilization and is therefore critical to submit well in advance of the planned mobilization date.

4.0 Materials. USACE shall furnish and deliver state-spec crushed gravel to the staging area (see Map 2) to be used as final trail tread at an estimated quantity of 245 tons. Gravel will be delivered prior to the start of construction activities. In the event the gravel quantity is insufficient, the contractor is responsible for contacting the Government a minimum of 5 days before additional material will be needed in order to coordinate delivery of said materials.

Excess gravel left at the staging area will be removed by the Government following contract completion. Gravel placed in excess of a 4-inch lift that results in the contractor’s need for gravel quantities beyond this estimate will not constitute a need for additional payment due to the increased volume of gravel requiring placement to finish construction of the trail.

5.0 Miscellaneous Execution Requirements

5.1. Participate in an on-site post-award meeting with U.S. Army Corps of Engineers (USACE) key personnel to review the entire Task Description, schedule, deliverables, submittal dates, and expectations for the final deliverable.
