1.3 CONTRACTOR USE OF SITE

A. General: Contractor shall have limited use of the site for construction operations. Limit use of premises to areas within the Contract limits indicated on the site plans. Limits of Construction are to be edge of existing cave trails for this section. Do not disturb portions of Project site beyond areas in which the Work is indicated.

1. Tour Routes through Snowball Dining Room and Grand Central Station will remain open and in use for tours certain time of the year. See Sheet G6 for additional information.

Contractor shall maintain access throughout the site for National Park Service administrative and other official business throughout the construction phase. Contractor shall implement all measures necessary to minimize disruption to tours in other parts of the cave and in particular to the tours accessing the cave through the same entrance used by the Contractor's personnel.

2. The Contractor will be expected to observe all of the requirements of Mammoth Cave

National Park regarding construction in the cave. Included among these requirements are no tobacco use of any form; removal of demolition materials on a daily basis; protection of the cave features, control of dust and noise, and White Nose Syndrome protocols.

3. Smoking within buildings, temporary storage sheds or within the cave or within 200 feet of cave entrances is strictly prohibited. E-cigarettes/vaping is also prohibited. Any

Contractor employees that are caught smoking on the project in these areas will be promptly removed from the cave and will be banned from working on the project. All other uses of tobacco are prohibited

4. There are sensitive natural and cultural features in the cave. The Contractor's employees will only be permitted to be off the cave trails where it is necessary to carry out the work of this project. Removing or damaging any natural and/or cultural feature of the cave is a violation of Federal Law and those caught doing so will be prosecuted to the full extent of the law. The terms removing or damaging are inclusive of writing, marking, adding graffiti, or otherwise defacing cave features. Reference Federal Regulation 36 CFR 7.36 for specific language regarding "off trail" restrictions. It is unlawful to disturb or kill cave life including bats and crickets.

5. Only Contractor employees specifically working on the job during normal Contractor working hours will be permitted in the cave. Neither Contractor nor Contractor's employees shall be allowed to bring along family members or friends to the jobsite.

6. Contractor employees will be permitted to carry in sack lunches provided that there is no cooking or warming equipment used, and that all wrappers, trash and leftovers are carried out on the same day as such is brought in.

7. Contractor will be allowed to concurrently use multiple work crews within the project work limits during the work periods defined above.

B. Storage of Materials: Confine storage of materials to those locations designated and/or approved by the CO. Do not store materials in the passageway within the cave without approval from the CO, unless otherwise noted on the site plans. Above ground storage areas are shown on Sheets G3 & G4.

Primary staging area will be located at the Snowball Room. Secondary Storage Areas along the trail are identified on Sheets C2.01 to C2.39.

MACA - 227188 01 11 00 - 3

C. Preservation of Natural Features: Confine all operations to work limits of the project. Prevent damage to natural surroundings. Contractor will be responsible for the costs of repair work to any cave walls and features damaged as a result of his operations.

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 that they are included in the hourly rate shown, or contractor is not requesting reimbursement.

Contractor may utilize the government provided Contractor Estimate Form, or their own form, provided that it contains the same information and level of detail as the Gov’t provided form.

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.

a. U.S. Army Corps of Engineers, Ownership and Operating Expense Schedule (use latest edition and applicable region)

b. Construction Blue Book

c. Local equipment rental rates, documented by actual invoice charges, or itemized vendor quotes.

Mobilization, if applicable, may be included for equipment solely used on the modification work but must be listed separately.

5. Estimate the full rate for equipment only for the duration that the equipment will be utilized to accomplish the work of the modification.

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.

Negotiated rates shall not exceed the following percentages for OH&P for contractor self-performed work:

Overhead………………10% Profit………………10%

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.
