DIVISION 1 GENERAL REQUIREMENTS

SECTION 01110 SUMMARY OF WORK

1.1 EXISTING CONDITIONS

The Project location is the Lake Mead National Recreation Area. The site is located near the Echo Bay Cove developed area.

The Echo Bay water intake barge provides drinking water to the water treatment. The intake barge was recently relocated to place the barge in deeper water as the water elevation of Lake Mead continues to decrease. A single string of wave attenuators was placed around the current water intake barge location.

The purpose and need for this project is to modify the breakwater and wave attenuator system to the water intake barge located at Echo Bay. Due to the lowering water levels in Lake Mead, the water intake barge has been relocated into deeper water of the lake. The current location of the barge out in deeper water puts the barge further out into the main body of the lake. The intake barge is now exposed to more of the weather including wind and waves. The barge has equipment including pumps and controls that will have a longer service life where a more stable platform is provided.

There are remnants of an existing breakwater at the location. The breakwater is secured by cables and anchors. The current breakwater has failed and is not useable.

This project will install a breakwater/wave attenuators or approved equal around the existing floating water intake barge.

1.2 GENERAL PROJECT STATEMENT

A. The work of this section consists, in general, of furnishing all labor, materials, equipment, tools, transportation, and incidentals required to design, fabricate, and install a floating wave attenuator. All floating wave attenuators shall be fabricated from structural steel and concrete. All material shall be compatible and intended for the freshwater (marine) environment. The approved floating wave attenuator shall be furnished and installed complete, including anchoring system (winches, cables, and anchor blocks), solar mounted lights, connecting hardware, and appurtenances.

B. A site visit will be scheduled for a pre-bid visit with the interested respondents. The site visit will be to an overlook where the barge site can be viewed.

C. Contractor shall provide their own equipment and transportation to and from the construction site including their use of boats and work barges.

D. On November 8, 2023, a site visit was conducted. The boat’s depth gauge at the intake barge read 110 feet. The Bureau of Reclamation recorded the Lake Mead surface elevation as 1065.07’.

5. The environmental compliance contacts for this project are Clayton Merrill, Kelly Wallace, and Matthew D’ambrosi. For questions or additional information, contact the following people via email:

a. Kelly Wallace, Biologist: kelly_wallace@nps.gov

b. Matthew D’ambrosi, Biological Science Technician: matthew_dambrosi@nps.gov

G. Equipment Washing:

1. Equipment washing is required to preclude the introduction and spread of non-native species into the Park. Therefore, all equipment shall be cleaned outside of the Park before entering the Park. Equipment leaving the park for any reason must be re-washed before returning to the job site. Equipment that is moved from the job site, but remains within the original developed area, need not be re-washed prior to returning to the job site. It is also known that there are areas inside the Park that have non-native plants and weed species infestation. Therefore, before equipment can be moved from one developed area to another, it must be washed at the location identified on the Site Plan (see attached site plan and mileage table) to ensure weeds are not spread from one developed area to another.

2. The Contractor shall clean all equipment prior to the equipment entering Lake Mead National Recreation Area. It is recommended that cleaning be accomplished by hot water, pressure washing, using water only. All equipment surfaces shall be cleaned, with special emphasis given to the undercarriage. This includes, but is not limited to:

wheel wells, bumpers, radiator grills, springs, shock absorbers, wire harnesses, skid plates, oil pans, axles, frame ledges, buckets, tracks, belly pans, etc. Cleaning shall also include all dirt and debris inside the cab, or operator area. A Shop-Vac or commercial car wash vacuum system may be used for operator compartments, provided the method used effectively removes all visible debris. Equipment cleaning is for the purpose of removing any seed and soil accumulations to prevent the potential spread of non-native plant and weed species from outside the park to locations inside the park. Cleaning shall be performed in a manner that will reasonably remove all visible soil, plant and other foreign material. All equipment that requires washing shall be inspected by government personnel, or contractors/partners assigned to this duty, to ensure compliance.

3. Equipment that requires washing is generally defined as track or rubber-tired machinery intended for use primarily off-road. Examples include backhoes, loaders, earthmovers, graders, rollers, bulldozers, water trucks, etc; or four wheel drive or passenger vehicles that are driven in off road areas. Equipment may also be stationary, such as a material screening plant, conex storage containers, or a mobile office (mobile offices may be cleaned in the same manner as operator compartments

LAKE 254113 Page 13 of 59 as outlined in paragraph 2). The equipment is generally under the direct control of the contractor or sub-contractors, is likely to remain on the construction site for an extended period of time, and may contain adhered soil and seed from other project sites.

4. Equipment/Vehicles that do not require washing are defined as those normally used for highway driving only, and travel primarily on paved surfaces and well maintained service roads and parking areas (this includes approved staging areas). Examples include semi-tractor trailers, dump trucks, concrete trucks, pickup trucks, fuel trucks, service trucks, etc. These delivery and passenger vehicles are generally not under the direct control of the contractor, have no earth-moving function, and do not remain on the project site. These vehicles have a low probability of carrying adhered soil and seed from other projects. However, every vehicle and piece of equipment is subject to rejection from entering the park if there are obvious signs (covered in mud, plant material adhered to it, etc.) that it could be transporting non-native species into the Park.

H. Post Equipment Washing Inspections:

1. All equipment subject to inspection will be inspected by government, or other authorized personnel prior to leaving the paved surface or designated washing area identified on the Site Plan. Equipment determined to be free of soil or mud based on visual examination by government personnel will be cleared to enter the project area, or proceed to other areas of the park as appropriate. The Contractor shall arrange for needed inspections by contacting the NPS inspection office no less than 5 working days prior to the inspection. Such contact shall provide sufficient time to accommodate scheduling and travel to the site. Equipment not passing initial inspection must be rewashed outside the park at no additional expense to the government.

2. A list of government Inspectors for this project will be provided by the list below.

Please contact via email all members and coordinate designated representative for inspection:

a. Kelly Wallace, Biologist: kelly_wallace@nps.gov

b. Matthew D’ambrosi, Biological Science Technician: matthew_dambrosi@nps.gov
