Contractor shall provide suitable signs and barriers, barrier tape or barricades necessary to warn people of and protect people from the operations necessary to complete the work of this contract. Work shall be coordinated with the COR to provide the least impact on park operations and inconvenience to park visitors and employees.

Contractor shall take all necessary precautions to prevent fire during this contract work. Internal combustion equipment shall be located by the Contractor so that exhausts discharge well away from combustible materials. The Contractor shall provide a minimum of one fire extinguisher at each location which is appropriate for each type of fire that could occur on the location.

Material used on this project can be stored on site. Storage lockers can be left onsite during contract.

Contractor shall keep work area neat at the end of each workday and contained through the duration of the job.

Work at jobsite will be scheduled in advance to allow for sufficient notification of staff and partners of potential noise, odor, and traffic interruptions.

SUBMITTALS

Contractor shall develop a binder and electronic file for contracted structures which includes manufacturer’s product information sheets for materials used.

Contractor shall provide manufacturer’s Material Safety Data sheets (MSDS) for all the products used in the work of this contract. These MSDS sheets must contain health and safety information on the product and will serve as guidelines for safe handling and storage of the products during the contract work for each structure file.

DELIVERY AND ACCEPTANCE

After the Government accepts the work of this contract, the Contractor shall submit a letter of warranty which will provide for the materials and labor to repair or correct any defects or problems that might occur within the one-year warranty period following acceptance.

When Contracting Officer determines that the work is substantially complete, he/she will prepare a list of any deficiencies to be corrected before final acceptance and issue a Letter of Substantial Completion. If Contracting Officer determines that the work is not substantially complete, he/she will immediately notify the Contractor in writing, stating reasons. After completing work, Contractor shall resubmit certification and request a new final inspection.

Acceptance will be complete when COR completes a walk-through of the contracted completed award, any punch list items are identified and completed, and required documents are provided by contractor to the COR. After all deficiencies have been corrected, and all submittals are received, a Letter of Acceptance will be issued to the Contractor from the Contracting Officer.

PERIOD OF PERFORMANCE

Work should take approximately 10 months to complete from time of award.

SEASONAL BAT RESTRICTIONS

Contractor will comply with New Jersey Fish and Wildlife Guidelines that apply to roof work during the year if nesting bats are present.

1) If no evidence of bats, the roof work may be done without season restrictions.

2) If just shingle/surface replacement, then the following work dates are recommended:

· April 1-30

· August 1-Oct 15

· October 16 - March 31 (only if there are no big browns overwintering in the buildings) The later end of the fall period is likely better as there's a lower chance of bats still being around, but emergence/surveys would better inform that.

3) If big brown bats are hibernating in the building, then avoid the work from Oct 15 to March 31.

Note: If the bats are not actually being excluded from the building first, it's possible that bats could be unintentionally harmed during the demo/renovation process or that contractors could be exposed to bats while removing old material.

If the timing is somewhat flexible, someone could monitor the colony's activity starting in late July to see whether & how many bats are still emerging at dusk, and the project could start once most or all of them have left for the season (presuming they will). The work could certainly continue past Oct 15 if the bats seem to have left. If the timing is not flexible, the contractors should be aware to be careful and methodical about the demolition, as harm to the bats would be a violation of NJ's Endangered and Nongame Species Conservation Act.

Some monitoring during the project would help you to know if bats are still day-roosting in the building while renovations are being done; you'll want to be careful not to seal them into the roost when the new roof is completed.

SITE VISIT

A site visit is encouraged so that potential bidders are aware of the location and conditions of the work requirements. Site visits can be scheduled.

SAFETY & COMPLIANCE

The contractor shall submit a written Accident Prevention Plan that complies with the Ooccupational Safety and Health Act (OSHA), 29 CFR 1910, and state, local, safety, laws.

The contractor shall comply with pertinent Environmental Protection Agency laws and regulations.

The contractor shall immediately report to the Contracting Officer and COR, all accidents resulting in employee injury or death or damage to property while performing this contract.

PROTECTION OF PROPERTY

Contractor shall exercise caution and care to prevent unnecessary conflict with, or potential hazards to road users, NPS employees, or park visitors. The Contractor shall be held liable for any damage caused by his personnel or equipment to any existing structures such as buildings, landscape, bridges, culverts, signs, guardrails, or any other Government infrastructure or property. Repair or replacement to these structures shall be at the Contractor’s expense. The Government shall not be liable to loss, damage, or destruction of equipment furnished by the Contractor.

INVOICING AND PAYMENT

Invoices must be submitted via the current electronic (IPP) government online payment system plus one copy to COR via email. Contractor must be registered and remain current in sam.gov. Invoices may be submitted for payment when work is completed and inspected by the COR.
