The Park requires, and will perform, inspections to ensure non-transport of non-native species PRIOR to arriving at the park entrance. Contact the CMR at least seven (7) days in advance of park entry to arrange for inspection(s).

LAKE – PMIS #324894 01 11 00 - 8

2. Endangered Species: Endangered species are protected by Federal law. Obey all park regulations. Drivers must obey all traffic laws and keep an eye out for animals on or alongside road. Contact CO immediately if animal is hit or injured or will not move off the road. All contractor’s personnel working in Lake Mead National Recreation Area must have up-to-date Lake Mead Desert Tortoise awareness training. Prior to starting work, contact the CMR at least seven (7) business days in advance to schedule the Desert

Tortoise awareness training.

The following endangered species are found within the park and require certain considerations.

a. Desert Tortoise – Desert Tortoise are frequently along the roadsides at Lake Mead

National Recreation Area and do not readily move when approached by cars. If there is a Desert Tortoise on the road, drivers must stop and allow the Desert Tortoise to move away on its own.

b. Razorback Sucker – Lake Mead is considered a critical habitat for razorback sucker.

Razorback suckers are known to use the waters near the project location as a spawning area. Therefore, water-based construction activities shall not occur during spawning season, December 1 through May 1.

Prior to the start of in water work, the Contractor shall conduct a survey of the work area with a trained diver to verify that no evidence of Razorback Sucker spawning is present. If spawning is discovered, notify the Contracting Officer and cease construction activities.

3. Archaeological Resources: Archaeological resources are physical evidence of past human activity, including evidence of the effects of that activity on the environment.

Archaeological resources are found above and below ground and underwater. If the

Government furnished archaeological monitor discovers resources, the contractor shall stop work and contact the contracting officer and/or construction management representative immediately. Archaeologically sensitive areas and resources typically found in the park or at the project site will be discussed further at the preconstruction meeting.

4. Soundscape / Noise: The contractor shall minimize noise levels at the project site to protect the soundscape of the park. Perform noise-producing work in less sensitive hours of the day or week or as directed by the contracting officer.

1.14 EXCESS EXCAVATION HAUL ROUTE AND PLACEMENT LOCATION

All saturated excavated spoils shall be placed in the new parking lot location for decanting and ar-chaeological monitoring prior to being hauled to the old sewer lagoons site. See plans.

LAKE – PMIS #324894 01 11 00 - 9

All excess excavation shall be hauled and placed at the old sewer lagoons as directed by the Contract-ing Officer. The Contractor shall collect soil samples and have laboratory tests completed for heavy metals with a report for the waste site prior to any placement of excess excavation. Quantity and loca-tion of the collected samples shall be as directed by the Contracting Officer.

The waste site is located ~2.7 miles from the project at the “old sewage lagoons” through the Lake

Mead RV village at Echo Bay. The shape, depth and size parameters of the waste site shall be deter-mined by the Contracting Officer. No revegetation efforts are necessary for the waste site. The fol-lowing map shows the location of waste site in reference to the project location:

Corp of Engineers is utilized then their standby rates prevail. If Bluebook or local equipment pricing is accepted, then 1/2 of 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, established standby rate shall apply from the first day of the delay.

8. Equipment not used and on job site for up to five consecutive days may be classified at standby rates, provided the equipment is or has been used solely to perform work on the modification and will be necessary to complete additional modification work.

Equipment 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:

1. Home Office Overhead and Profit (OH&P) shall be applied to direct costs only. Profit shall not be applied to overhead amounts; and overhead shall not be applied to profit.

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…………………...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, partnership may only receive home office overhead and profit in same amount as an individual Contractor (refer to paragraph 1.3,E,1 above). It is the responsibility of the partners to decide on division of revenue.

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