SECTION 01 11 00

PART 1 – GENERAL

1.1 SUMMARY

A. This Section includes the following:

1. Work covered by the Contract Documents.

2. Work phases.

3. Contractor use of the site.

4. Public use of the site.

5. Buildings.

6. Work Restrictions.

7. Special Construction Requirements.

8. Work under other contracts.

9. Government Furnished Materials.

10. Occupancy requirements for buildings.

11. Additional Reports.

1.2 WORK COVERED BY CONTRACT DOCUMENTS

A. Project Location: This project is located at the Meriwether Lewis Site in TN. Meriwether Lewis is located Mile Post 385 on the Natchez Trace Parkway and intersects with Highway 20, or Summertown Highway. There is an entrance into Meriwether Lewis area off the Summertown Highway and it’s the preferred entrance for equipment and material delivery.

B. The work consists of the following:

1. The project consists of the demolition and replacement of the existing roofing systems and failed components.

It’s estimated that 40% of the flat roof decking is estimated to need replacing along with some of the support structure joists as well. The preferred alternatives consist of a traditional, 25-year or better asphalt shingle, replacing in kind or better and matching the color as close to the current color as possible for those sections on the sloped portion of the office building. Removing material to the deck, replacing any bad deck, and finishing with new Ice & Water Barrier, Moisture Barrier, Drip Edge, Shingles, and Flashing, the preferred alternative for the flat sections would be a light-colored EPDM roofing system on the office and equipment storage roof with associated insulation, adhesive layer, fasteners, and plates.

2. Solar Panels will need to be removed from some roof sections along with some sections of their mounting hardware, both sloped and flat, where they are currently attached. The contractor shall have a certified electrician or certified solar installer disconnect the current panels, ensuring removal can be done safely. The contractor shall then have a certified electrician or certified solar installer reconnect all solar panels once the roofing project is complete.

C. The project will be constructed under a single prime contract.

D. Project Contacts:

1. Contracting Officer (CO): TBD; Interior Region, South Atlanta Gulf

2. Contracting Officer’s Representative and Project Manager; will be Steven "Mark" Holley; Natchez Trace Parkway, 2680 Natchez Trace Parkway, Tupelo, MS 38804; (662) 680-4054; Steven_Holley@nps.gov

3. Park Civil Engineer Contact: TBD but currently Steven Mark Holley, 2680 Natchez Trace Parkway, Tupelo, MS 38804; Office

(662) 680-4054, Steven_Holley@nps.gov.

4. Park Safety and Occupational Health Manager; Myranda Spear, 2680 Natchez Trace Parkway, Tupelo, MS, 38804; Office (662) 680-4010; Myranda_spear@nps.gov

1.3 WORK PHASES

A. General: Contractor shall have use of the site for construction operations. Limited use of premises to areas within the Contract limits indicated. Do not disturb portions of the Project site beyond areas in which the Work is indicated.

1. Limits: Confine construction operations within the designated perimeter of the site (pavement areas) unless otherwise instructed.

2. Utilities to support construction activities by the contractor:

a. Water: Contractor may use water from the existing facility by coordinating with the district supervisor. All water use must be directly associated with a necessary need to complete the contract.

b. Power: The contractor may use power from existing facilities by coordinating with the district supervisor. Acceptable uses are for equipment associated with the direct construction of the project. The objective of allowing the contractor to utilize power at facilities is to limit the use of portable generators, when possible, to reduce noise and greenhouse gases (carbon footprint of the project).

3. Restrooms: The contractor is required to provide Portable Toilets for their staff. The interior restrooms are not available for contractor employees. Location of the portable toilets will be determined by the district supervisor of Meriwether Lewis or the Contracting Officers Representative.

4. Erosion control measures will be following the approved UPPP when necessary.

D. Driveways and Entrances: Keep driveways and entrances serving premises clear and available to Government, Government employees, and emergency vehicles. Do not use these areas for parking or storage of materials. There may be times when the work area next to the building will need to be utilized for equipment, ladders, etc. Limited access to this area can be arranged with prior approval from the Contracting Officers Representative or the District Supervisor of Meriwether Lewis. All ABA designated entrances will need to remain accessible but can be temporarily closed to ensure the safety of anyone using that entrance.

1. Schedule deliveries to minimize the use of driveways and entrances.

2. Schedule deliveries to minimize space and time requirements for storage of materials and equipment on-site.

Labor costs must be itemized by craft and hourly rate, including Fringe Benefits and Labor, Burden. If the costs of Fringe Benefits and Labor Burden are not itemized, it is assumed that they are included in the hourly rate shown, or the contractor is not requesting reimbursement. The contractor may utilize the government provided Contractor Estimate Form or their form if it contains the same information and level of detail as the Government provided form.

3. Requests for extensions of contract time because of this change, must be justified with a Time Impact Analysis (TIA).

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. The 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.

7. If the 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 job site 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 job site 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.
