1 INTRODUCTION

1.1 LOCATION & DESCRIPTION OF PARK

First State National Historical Park

Brandywine Valley unit 400 Ramsey Road Wilmington, DE 19803

First State National Historical Park (FRST) is made up of six sites spread throughout the state of Delaware. The Brandywine Valley unit (previously known as Beaver Valley) and the Sherriff’s House in New Castle are owned and managed by the National Park Service, while the remaining five sites are owned and managed by state and local partners who provide tours and programs to the public.

Brandywine Valley unit consists of approximately 1,359 acres of rolling hills and wooded areas along the Brandywine River and the arced border between northern Delaware and southern Pennsylvania. It is an integral component and legacy of Quaker industrialist William Poole Bancroft’s vision for open park lands and the conservation of green space as part of his larger philanthropic community planning experiment in the City of Wilmington that drew upon national and international currents of early 20th century social and industrial reform.

1.2 BACKGROUND

First State National Historical Park has vestiges of quarries at the Brandywine Valley unit. The Ramsey Quarry site covers approximately 0.64 acre and is located about 1,000 feet north of Ramsey Road. The largest surface mine feature is approximately 65 by 60 feet with a steep drop off about 28+ feet deep. The Beaver Valley Quarry covers approximately 1.69 acres and the is located about 500 feet from Walker Road. The two largest surface mine features are approximately 120 by 100 feet with unknown depth and 130 by 56 feet and approximately 50 feet deep. All the site features are within 10 feet of the existing multi-use trail system.

The sites have been characterized and assessed for environmental and safety hazards. This project proposes to install fencing and signs around the surface mines. The proximity of the quarry features to the trail is of great concern for visitor safety as some features are not highly visible to trail users and there are steep drop offs on the largest surface mine features.

Additionally, several of the surface mine features are being actively used by mountain bikers causing earth movement along the edges and/or within the features.

1.3 Site Visit

To be determined when this scope of work is distributed.

2 SCOPE OF SERVICES

The work outlined herein calls for the installation of pressure treated split rail fencing surrounding quarry features. The contractor will install approximately 3,450 feet of fence to mitigate safety risks at two abandoned surface mining sites and reduce impacts on cultural and natural resources, including access gates and signage.

The Contractor shall furnish all equipment and sufficient personnel for the installation of the fencing and gates, and all related incidental work as in accordance with the bid schedule and specifications stated herein.

6 Execution

6.1 Materials

6.1.1 Fencing

The fence posts to be used are 5-in x 3-in x 7-ft pressure treated yellow pine, flat-top split rail line with three (3) notches. The rails to be used are 4-in x 11-ft pressure treated yellow pine. Hot dipped galvanized or stainless-steel fasteners and fittings are acceptable for use with treated wood. Fence installation will also require gravel.

Flex fence non-electric rail wire constructed of 12.5 gauge high-tensile wire coated in polymer including specialized tensioners and brackets.

6.1.2 Gates

Four access gates will to be used. Gates shall be 10 ft. x 4 ft. 2 in. 6-rail powder-coated tube gates. Installation of gate shall include gate hinges, screw hooks, and locking mechanism hardware.

6.1.3 Signage

Eight (8) warning signs will be fabricated (Fig. 4). Materials shall include all hardware to attach to access gates.

Sign specifications are as follows:

Size: 12” x 18”

6.2 Fence installation

6.2.1 The contractor will plan and lay out the fence perimeter using batter boards and a string line, or other appropriate means.

6.2.2 The contractor will verify lay out with the POC or COR before installation.

6.2.3 Post holes may be dug with either a hole digger, auger, or power driven. The holes should be about a third as deep as the posts are tall plus 4 inches. The diameter of the holes should be three times the width of the post. The Contractor must ensure that the bottom rail will remain several inches above ground.

6.2.4 Each post hole will be filled with 3-inches to 4-inches of gravel down the base of the hole for proper drainage. The gravel will be tamped down using the bottom of the post or a tamper.

6.2.5 The posts shall be level and aligned so that the openings run in the right direction to meet up with the rails.

6.2.6 All excavated materials shall be retained and used to backfill post holes. Backfill the post holes with excavated materials and tamp down.

6.2.7 Once the posts are set, starting at the bottom, slide the rail into one post until it clears the adjacent post, then slide it into the adjacent post. Continue on until all of the rails are installed, making minor adjustments as needed. Then adjust each rail so that it overlaps both posts evenly.

6.2.8 Corner bracings shall be used where appropriate.

6.2.9 The flexible fence rail attaches directly to the end fence posts using specialized tensioner and termination brackets. The length of the high-tensile fence rail is held in place with custom line post brackets that allow the rail to slip freely. Flexible rail should be installed on a 4 in. to 6 in. wood line post and a 6 in. to 8 in. wood termination/end and corner post. Due to the nature of this high-tensile field fence, bracing of posts is recommended.

6.3 Signage installation

6.3.1 One sign shall be installed on each access gate using best fit measures with adequate hardware.
