1.3 CONTRACTOR USE OF SITE

A. General: The Contractor shall have limited use of the site for construction operations. The Contractor shall at all times conduct his operations to ensure the least inconvenience to the building occupants.

Building closures and closures or blockage of doors, driveways, and roads will not be permitted, except for short term durations and approved schedules per Section 01 32 16. Continued operation of all buildings and functions in the camps is required.

B. The Contractor is required to provide temporary power to maintain operations.

1. Continuous operation of the Search & Rescue Facility, Ranger Office, and the AT&T and

Telecom equipment is especially critical and shall not be interrupted for periods exceeding one hour.

2. Access to employee housing, restrooms, barn, stables, shower houses, and kitchens are also critical for park operations and power shall not be interrupted for more than four hours.

3. Advance notice of power interruptions is required a minimum of 10 working days, with notices posted by the Contractor on each affected building with weather resistant signage.

C. Park escorts shall be required inside buildings in use unless otherwise allowed by the CO and occupants.

D. Limits: Confine constructions operations to rooms and spaces where work as drawings indicate.

E. Storage of Materials: Confine storage of materials to preapproved areas as directed by the Contracting Officer. An outdoor staging area will be designated at the project site by the Contracting Officer. The staging area will be approximately 50’ x 20’ in the Dog Lake Parking Area. There will be park visitors, park maintenance, employees, and truck traffic around and near this area during construction. The Contractor shall submit a Staging Plan and Map for approval showing the desired locations of dumpsters, hazardous materials enclosures, clean areas, materials storage, equipment, and debris removal schedules. The Staging Plan shall be reviewed and subject to approval by building users and the CO. The Contractor shall return all storage and staging areas to the same condition that they found them at the start of construction.

F. A Contractor’s office trailer and two small travel trailers are allowed in the old Dog Lake Parking Lot. The trailers shall be self-contained, as there is no power, water, sewer, or telephone at this location. The contractor shall have no access for use of NPS facilities such as the showers, laundry, or restrooms. The Contractor shall locate his trailers and staging area to allow vehicle and pedestrian circulation and parks for public use access to the Dog Lake Trailhead and to ensure NPS staff and maintenance access to Bug Camp. The Contractor shall take documentary photos prior to staging and restore the site to its original condition at the end of the project. Trailers or equipment shall not remain over the winter. Design snow levels for this area are 375 pounds per square foot and 10 feet of snow is not uncommon over the winter. Contractor will be required to perform snow removal as required for construction access when access is allowed by Yosemite CO, which may be possible during shoulder seasons when the camps are being set up or shut down, and park plowing operations are not occurring (contractor traffic on roads being actively plowed pose an unacceptable safety risk

YOSE – 228214, 228193, 228205 01 11 00 - 4

10309975 to all parties and will not be allowed). Winter access will not be allowed at any time as the area reverts to Wilderness by law and vehicular access is not permitted.

G. Preservation of Natural & Cultural Features (see also Sections 01 35 13 YNP Natural, Cultural, and Physical Resource Protection, 01 35 60 Tribal Cultural Monitoring, and 01 35 91 Historic Preservation Treatment Procedures):

1. Project building is included in the Tuolumne Meadows Historic District. Building surfaces shall be considered historic and not disturbed unless specifically noted in the Contract Documents. All modifications are subject to the review and approval of the Yosemite Historic Architect and/or Yosemite Historic Preservation Shop.

2. Prevent damage to natural surroundings. Restore damaged areas, repairing or replacing damaged trees and plants, at no additional expense to the Government.

3. Provide temporary barriers to protect existing trees and plants and root zones.

4. Do not remove, injure, or destroy trees or other plants without prior approval. Consult with

Contracting Officer and remove agreed-on roots and branches that interfere with construction.

5. Do not fasten ropes, cables, or guys to existing trees.

6. Carefully supervise excavating, grading, filling, and other construction operations near trees to prevent damage.

7. Do not remove native soils except as shown on the Contract Drawings.

8. Provide archeological and tribal monitoring and reporting for ground disturbance activities, including trenching, required to complete the work of this project.

H. Driveways and Entrances: Keep driveways, access roads and entrances serving premises clear and available to the Government at all times with the exception of the preapproved storage and staging areas as within the limits as shown and/or as directed by the Contracting Officer. The area is not fenced or locked. The Contractor shall provide his/her own security while keeping access open for park operations. The Contractor shall provide a construction key to the COR and the park Fire Department for access in the event of a fire or other emergency.

1. Do not use these areas for parking or storage of materials.

2. Schedule deliveries to minimize use of driveways and entrances.

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

I. Construction Camp: Establishment of a camp consisting of two small self-contained travel trailers shall be permitted at the older Dog Lake Parking Lot. Contractor crews shall observe all park rules and regulations, including quiet hours (9 PM to 7 AM) and food storage requirements.

J. Hauling Restrictions: Comply with all legal load restrictions in the hauling of materials. Load restrictions on park roads are identical to the state load restrictions with such additional regulations as may be imposed by the Park Superintendent. Consult with, and receive written permission from, the Contracting Officer prior to bringing any vehicles or equipment requiring Caltrans special permits for size or weight. Permission is not guaranteed. A special permit will not relieve Contractor of liability for damage which may result from moving of equipment. Wide loads require permits and escorts from the park traffic management and law enforcement office, with a minimum two week notice, and transport is required to occur during normal work hours when escort staff are available.

1. All park roads are subject to snow and icy conditions. It is required that you carry Caltrans approved tire chains or cables when visiting Yosemite as a sudden snowstorm could make

YOSE – 228214, 228193, 228205 01 11 00 - 5

10309975 them mandatory. Vehicles with a gross vehicle weight (GVW) of greater than 6000 pounds must use tire chains/cables when chain controls are activated at any level.

2. The primary access to Tuolumne Meadows is via CA Highway 120 (Tioga Pass Road) from either the east or west sides of the park. The Contractor is responsible for knowing and complying with any/all vehicle restrictions imposed by Caltrans or Yosemite National Park on this or any other highway utilized for access to the Project location.

3. The Tioga Pass Road portion of CA Highway 120, which includes the Project location in Tuolumne Meadows, is a seasonal highway which is closed each winter. Refer to Specification Section 01 50 00 for additional road closure information. There is no access to the Project location when Tioga Pass Road is closed, either by the park, or by Caltrans at the access points outside of the park. It is the Contractor’s responsibility to monitor weather conditions and the most up to date information regarding the road status and to plan the work accordingly. During the shoulder seasons temporary closures are common due to periodic snow storms.

a. If seasonal closure of the Tioga Pass Road occurs during the performance period of this contract, the Contracting Officer will work with the Contractor to institute a seasonal suspension of the work under conditions acceptable to both parties. The Contractor shall not make any claims for regular seasonal closure of Tioga Pass Road.

4. Aside from the seasonal closure of Tioga Pass Road, other delays or intermittent closures may occur on any park roads or any highways providing access to the park at any time due to rockslides, road washouts, and related issues. These shut downs occur with little to no notice. Heavy visitor traffic and road construction will cause delays, especially during peak travel times. The Contractor shall not make any claims for traffic delays or intermittent closures of any park road or any highway providing access to the park. The Contractor shall include five (5) work days of temporary shut down of Tioga Pass Road during each construction/summer season for weather or other events for which he will not be compensated. These temporary shut down days shall be dispersed throughout the schedule.

5. It is the Contractor’s responsibility to obtain the most up to date information on road restrictions and closures, and to comply with all rules and regulations for vehicular traffic to and from the project site. The Contractor shall perform snow removal at the camps if required for construction. Yosemite crews perform snow plowing operations of the Tioga Pass Road when conditions permit during the spring opening, but do not plow the camp areas and will not perform plowing for Contractor access.
