PART 1 – GENERAL

1. DESCRIPTION OF WORK

1.1 Background

The National Park Service (NPS), Apostle Islands National Lakeshore (APIS), has identified two existing marine navigation/light-related structures located offshore at Long Island near the Bayfield Peninsula that are exhibiting significant racking, out-of-plumb conditions, and structural instability. Both structures are actively leaning toward Lake Superior and are at risk of progressive structural failure and collapse into navigable waters. These conditions pose a safety hazard to the public, park staff, and marine traffic, and present a risk of environmental damage and debris deposition into Lake Superior.

The existing structures consist of:

• Chequamegon Light Tower– An older elevated steel-framed lighthouse structure with an enclosed lantern house and corroded steel cladding supported on steel legs founded in the lakebed.

• Cylindrical Steel Tower – A newer steel tower founded on a concrete base, equipped with mounted navigational equipment.

Both structures are located in shallow nearshore waters and are subject to wave action, ice loading, corrosion, and ongoing foundation instability.

Purpose of Project: Safely decommission, dismantle, remove, and transport both structures to the mainland in their entirety, including all above-water components, to eliminate safety hazards, prevent uncontrolled collapse, and protect lake resources.

All work shall comply with NPS standards, applicable federal and state regulations, and accepted marine demolition practices.

1.2 Work Covered by the Contract Documents

The work includes the following:

• Project Location: Long Island, Apostle Islands National Lakeshore, Bayfield County, Wisconsin. The site is offshore along the southern shoreline of Long Island which is located in Ashland County.

• Mobilization of marine access equipment including barge(s), workboat(s), excavator, and temporary shallow-water platforms and/or matting.

• Disconnection and removal of solar equipment from the cylindrical steel tower.

• Controlled dismantling and transport to the mainland of the historic elevated steel-framed light structure with care to minimize damage.

o All components to be labeled, palletized, and secured for forklift transport.

o Structure to be accompanied by documented inventory sheets matching structure labeling.

• Removal of the non-historic cylindrical steel tower, including mounted fixtures and steel shell sections, for disposal on the mainland.

o Contractor responsible for the disposal/recycling.

• Concrete foundations should not be removed or altered as they lie below the waterline and would require additional environmental compliance and permits.

• Cutting, lifting, and removal of all debris, ensuring no materials fall or remain in the lake.

• Transportation of all removed materials to the mainland, furnishing tower materials to

NPS and taking cylindrical tower to approved disposal or recycling facilities in accordance with NPS, EPA, and state requirements.

• Temporary turbidity control, debris containment, and environmental protection during in-water work may be necessary depending on means and methods of removal.

• Final site cleanup and closeout documentation.

• All work shall be performed under a single contract.

• Period of Performance: 90 calendar days.

1.3 Existing Condition Protections

A. Preservation of Historical and Archeological Fabric

The Historic and Archeological Data Preservation Act of 1974 applies.

Although this project involves no digging/unearthing the following applies:

• If historical or archeological remains are discovered:

• Suspend operations within a 50-foot radius.

• Notify the Contracting Officer immediately and follow up in writing with photos within 2 days.

• Do not remove objects of cultural value.

• Contracting Officer may order delays or changes; time and price adjustments will follow the Changes clause.

• Contractor is responsible for protecting cultural resources and liable for any damage.

• Include this language in all subcontracts.

B. Historic Structure Protection

The structure is listed as eligible in the National Register of Historic Places. The structure already has accrued severe damage. Contractor must take measures to prevent further damage to historical materials.

C. Protection of Landscaping and Surrounding Structures

Ground disturbance requires oversight by an NPS-provided Archeologist. Contractor must protect trees, fencing, walks, and other features. Any damage outside agreed limits must be repaired or replaced at no cost to the Government.

D. Protection of Natural Resources
