1.2 WORK COVERED BY CONTRACT DOCUMENTS

A. Project Location: The project is located on Bastion 6 at Fort Jefferson, Dry Tortugas National Park, Garden Key, in Monroe County, Florida. Garden Key is located in the Gulf of Mexico approximately 68 miles west of Key West. Garden Key is only accessible by boat or seaplane. The logistics of transporting personnel, supplies, materials and equipment to the Dry Tortugas and maintaining a productive construction site far from the mainland will require careful planning and coordination by the Contractor.

B. The Work consists of the following:

1. The Work of this project involves the conservation, repair and rehabilitation of the 1876 Tortugas Harbor Lighthouse located on top of Bastion 6 at Fort Jefferson, Dry Tortugas National Park. The work shall be completed in three phases; Lighthouse Disassembly, Lighthouse Treatment and Lighthouse Reinstallation. Due to the extreme conditions of the site, the lighthouse shall be disassembled and transported to the mainland for conservation and repair. Following treatment, the lighthouse components shall be transported back to Garden Key and the structure reassembled in its original location.

Phase I - Disassembly

Existing government-furnished scaffolding/shoring shall be modified by Contractor as needed to facilitate disassembly of the lighthouse. Contractor shall disassemble scaffolding/shoring in coordination with lighthouse disassembly and store on Garden Key where directed by Contracting Officer. Architectural and electrical components shall be removed in advance of disassembly of lighthouse structure. All components shall be lowered to grade within the Parade Ground and transported from the base of Bastion 6, through the sally port to the main dock area for loading on a vessel and transported to an

DRTO - 241934 01 11 00 - 2

off-site, contractor-furnished facility. It is anticipated the Contractor will complete disassembly prior to June 1, 2020. Hurricane Season commences on June 1st. In the event of severe weather/hurricane, the contractor shall commence with their sever weather/hurricane plan located within their approved Safety Plan, which shall include securing all resources and materials within 72 hours of projected landfall and be able to demobilize all personnel from Garden Key no later than 48 hours out from projected land fall. Contractor shall return to site for continuation/completion of Phase I work upon receiving all clear notification from Government. Existing Government-furnished scaffolding/shoring becomes property of the Contractor at Notice to Proceed and shall be modified, as necessary, to complete the work and shall be properly disposed of upon completion of work.

Phase II – Treatment

Lighthouse components shall be transported to a location where repair and conservation shall take place. Prior to treatment it will be necessary to further disassemble lighthouse components into smaller elements to accommodate conservation and repair. As part of the treatment scope, existing finishes shall be removed and hazardous materials abated.

Treatment shall also include the fabrication of new compatible wrought and cast-iron components to repair areas lost to advanced corrosion. NPS personnel and their representatives shall be allowed access to treatment facility in order to observe treatment process and evaluate progress. New high-performance corrosion-resistant, durable finishes shall be applied to all lighthouse components.

Phase III – Reinstallation

Phase III includes erection of Contractor-furnished scaffolding and repairs to the masonry of the Bastion 6 stair tower, including re-pointing and the setting of new anchor bolts in the masonry walls. The repaired and conserved lighthouse components shall be transported back to Dry Tortugas for reinstallation in their original location on top of Bastion 6. The conserved elements shall be lifted back into place using the Contractor-furnished scaffolding, beginning with the base and progressing to the lantern. New wood floor structure shall be installed along with new wood flooring, wall and ceiling paneling. These elements shall be replaced in-kind. Treated doors and shutters removed during Phase I shall be reinstalled and upgraded electrical power and lighting fixtures shall be installed in the lighthouse and stair tower. The lantern shall receive new glazing, upgraded light fixtures, new ventilator ball and new lightning protection system. Demobilization will include, but not limited to removal of scaffolding installed during Phase III and its transportation from the island. Phase III must be completed between the months of November and June.

All work shall be performed in a manner that minimizes impacts to Park operations and visitor experience.

C. Project will be constructed under a single prime contract.

1.3 WORK PHASES

A. The Work shall be conducted in three phases in the following order, with each phase substantially complete before beginning the next phase. Final determination of substantial completion will be made by the CO at the end of each phase.

DRTO - 241934 01 11 00 - 3

1. Phase I: Disassembly of lighthouse and government-furnished scaffolding and transportation off-island. It is anticipated the Contractor will complete disassembly prior to June 1, 2020.

DRTO - 241934 01 11 00 - 7

for its construction personnel to the site, rather than relying on commercial modes of transportation. While the Contractor may make arrangements for its personnel to be transported to the construction site on the Government’s crew boat, this vessel’s schedule and availability is uncertain and subject to weather conditions and other operational requirements such as staff scheduled maintenance, repairs, emergency assignments etc. Since this alternative method of transportation might be available but is not being provided as Government-furnished property/services, the Contractor shall be responsible for determining what method to use to transport its personnel to the construction site. If the Contractor chooses to use the Government crew boat and the crew boat is unable to make a trip, the Contractor shall bear all responsibility and expense for transporting its crew to the site; and this shall not be recognized as a Government delay of work or be an acceptable reason for the Contractor to make a request for equitable adjustment or additional time under the contract. The Contractor shall be responsible for making arrangements for the Government crew boat with the park personnel.

Information and restrictions that apply to passengers on the Government crew boat include the following:

1) All food items shall be placed in cardboard boxes or coolers labeled with the owner’s name.

2) All other cargo shall be labeled and easily identifiable as to the owner of the property.

3) The USCG Sector Key West base is accessed through the USN Key West Naval Air Station Trumbo Point Annex main gate. NPS staff (crew of M/V Fort Jefferson) must escort passengers through the USN main gate and USCG gate. Truck deliveries require a driver with a TWIC card and inspection of the vehicle at the USN Key West Naval Air Station Boca Chica entrance station.

4) The trip is approximately 5-1/2 hours of travel time from Key West to Dry Tortugas. The Government crew boat typically departs at 9:00 am from Key West Trumbo Point Naval Annex every other Tuesday. Return trips to Key West are generally the following Thursday, departing at 7:00 am from Dry Tortugas. There would be no charge for use of the Government crew boat when used with the normal operational schedule and solely for the transportation of Contractor personnel, groceries and personal items.

Scheduled trips are generally every other week. The Government crew boat is unavailable when the crew have scheduled leave, training, scheduled maintenance at a ship yard or have chartered trips supporting research. On an annual average basis, the Government crew boat will make approximately 18 resupply trips to Dry Tortugas.

5) Arrangements for use of the Government crew boat shall be made at least two weeks in advance of travel.

6) All Contractor personnel cargo shall be loaded, secured and unloaded by the Contractor or its personnel with guidance from the motor vessel Fort Jefferson crew. Contractor is not permitted to use crane on vessel. Crane shall

DRTO - 241934 01 11 00 - 8

be operated by ship’s crew. The Government is not responsible for lost or damaged goods.

7) The Contractor and Contractor’s personnel or subcontractors’ personnel shall present proper identification at the naval base gate and be escorted to the boat by a crew member of the M/V Fort Jefferson. The Government will not be responsible for personnel unable to access the boat prior to departure.

8) Private vehicles may not be parked overnight on the base. A small parking area is located directly outside the main gate and can be used to park privately owned vehicles. The Government shall not be liable for vehicle damage or theft if the Contractor’s or subcontractor’s personnel park their vehicle at this site.

9) Entry to the naval base may be denied anytime the national security level is elevated to orange or red or the naval base determines the individual(s) may not enter.

10) The Contractor shall be responsible for completing liability waivers for each person traveling on the Government crew boat. These waivers shall be presented to the captain prior to the Government crew boat getting underway.

B. Storage of Materials: Confine storage of materials to the North Coaling Dock or other designated staging areas indicated on drawings.

C. Preservation of Natural Features:

1. Prevent damage to natural surroundings. Restore damaged areas, repairing or replacing damaged trees and plants, at no additional expense to the Government.

2. Provide temporary barriers to protect existing trees and plants and root zones.

3. Do not remove, injure, or destroy trees or other plants without prior approval. Consult with

Contracting Officer and remove agreed-on roots and branches that interfere with construction.

4. Do not fasten ropes, cables, or guys to existing trees.

5. Carefully supervise excavating, grading, filling, and other construction operations near trees to prevent damage.

6. In the event that natural features are inadvertently damaged, Contractor shall notify

Construction Management Representative immediately.

7. Construction workers shall be educated regarding fishing regulations, including identification of protected species.

8. Roosting or foraging birds shall not be disturbed.

9. Minimize activities at night that produce light scatter, especially from May to September during turtle nesting season.

10. Care shall be taken to avoid impacts to sessile marine organisms such as coral and sponges.

11. Refueling and maintenance of construction equipment shall be conducted in designated areas over spill pads.

D. Preservation of Cultural Resources: Due to the elevated historic status of this resource, preservation treatment approaches shall concur with The Secretary of the Interior’s “Standards for the Treatment

DRTO - 241934 01 11 00 - 9

of Historic Properties,” along with The Secretary of the Interior’s Guidelines for Treatment of Cultural Landscapes.”

This property is listed on the National Register of Historic Places (NR) and managed as a cultural resource and local aid to navigation. It includes historic features such as structures, landscapes and associated landscape features (sidewalk, planters culverts, fences, site walls, retaining walls, etc. and engineering features such as bridges, towers, etc.) This significance also extends to subterranean items including undiscovered or unexcavated archeological resources. It is also possible that certain site features within the project boundary are not mentioned in the NR document, but those unnamed items are considered potentially eligible and are treated with the same level of concern.

During construction and transportation of lighthouse components, care shall be taken to protect all cultural and natural resources. When planning construction means and methods, preservation and protection of this resource is paramount. Contractor will proceed with care, using conservative and cautious approaches when working on and around historic fabric. Recognized and approved methods, favoring hand tools over power tools along with demonstrated experience and skill, will take precedence over radical and unproven procedures. If potential exists for irreversible damage or loss of fabric, contractor will cease work and seek guidance and approval from CO (Contracting Officer) before resuming work. Actions deemed detrimental to the resource, that would otherwise place the resource at jeopardy of loss to its historical integrity, regardless of cause, will not be undertaken without prior review and approval by CO.

E. Driveways and Entrances: Keep walkways, boardwalks, sally port and counterscarp clear and available to Government, Government's employees, and emergency vehicles at all times. Do not use these areas for parking or storage of materials.

1. Schedule deliveries, pick-ups/removals to minimize use of docks, seaplane ramp, counterscarp and sally port. Major delivery or pick-up of material shall not take place during peak visitor use times (10:00 am – 3:00 pm).

2. Schedule deliveries, pick-ups/removals to minimize space and time requirements for storage of materials and equipment on-site.

G. Hauling Restrictions: There are no standard roadways on Garden Key. Vehicular circulation is over dirt pathways and boardwalks where there are tight spaces and limited turning radiuses. Therefore only small vehicles can be used for transport of materials, supplies and debris. Comply with all legal load restrictions in the hauling of materials. (Dimensions of bridge and counterscarp and associated load restrictions are indicated on drawings). Information regarding rules and regulations for vehicular traffic on Garden Key may be obtained from the Office of the Park Superintendent. A special permit will not relieve Contractor of liability for damage which may result from moving of equipment.

H. Contractor shall install temporary roadway surface or protective mats along haul route within the fortification between the Bastion 6 staging area and Sally Port to minimize damage to existing turf and protect significant archeological deposits known to exist in the area.

I. Contractor shall store fuels greater than 5 gallons in containers with appropriate NFPA marking.

Refer to Division 01 Specification, “Construction Schedule”, for time impact analysis requirements. TIA and associated costs must be received with the proposal by the date shown within the Request for Proposal letter.

Contractor’s failure to submit within the specified time frame will be construed as the Contractor waiving the right for additional time and no time extension will be allowed.

4. All supporting documentation used to justify the proposed modification will be made available to the Contracting Officer upon request.

5. Contractor must review and approve all subcontractor/supplier pricing in detail for proper format, scope, production rates, and pricing prior to submission to the NPS. All delay costs associated with not reviewing and approving subcontractor/supplier pricing will be borne by the Contractor.

6. Standby unit rates used are to be in accordance with paragraph 1.3, D, 2, above. If the US Army Corp of Engineers is utilized then their standby rates prevail. If Bluebook or local equipment pricing is accepted, then ½ of the equipment costs minus any operating costs, major repair and overhaul will be accepted.

7. If equipment is in standby mode due solely to a documented NPS delay, the established standby rate shall apply from the first day of the delay.

8. Equipment that is not used and on the jobsite for up to five consecutive days may be classified at standby rates, provided that the equipment is or has been used solely to perform work on the modification and will be necessary to complete additional modification work. Equipment that is still on the jobsite but not in use after five consecutive days will not be considered in the modification pricing.

9. Requests for compensation for equipment stand by time must be justified, documented and itemized separately.

10. The estimated timeframe (daily, weekly, monthly) for use of the equipment must reflect the lowest cost to the Government.

E. Establishment and Application of Overhead and Profit Percentages:

Home office overhead shall contain only allowable, allocable, and reasonable costs per the contract documents and FAR Part 31. Profit percentages are based on risk factors found in FAR Part 31which have been applied to the specific type of work included in this project. Negotiated rates shall not exceed the following percentages for OH&P for contractor self-performed work:

Overhead………………10% Profit………………7.75%

2. Total aggregate limit of markup (OH&P) for contractor and subcontractors on modification work shall not exceed 25%. The NPS will not be responsible for allocation of percentages between contractor and subcontractors at any tier.

3. If contractors form a partnership, than the partnership may only receive home office overhead and profit in the same amount as an individual contractor (refer to par 1.3,E,1 above). It is the responsibility of the partners to decide on the division of revenue.

4. Combined Increases and Decreases: On proposals involving both increases and decreases in the Contract Price, the overhead and profit mark-ups are required on the net increases and deducted on net decreases.

5. At no time can profit be calculated on Overhead or itself, it must be calculated on direct costs of work only.
