GRCA - 318719 01 11 00 - 4

1.5 CONTRACTOR USE OF SITE

A. Limits of Construction (LOC): Contractor shall have limited use of site for construction operations.

1. Limit use of premises to areas within the Limits of Construction indicated on drawings. Do not disturb portions of the site beyond these areas. The Contractor shall clearly delineate the boundary of the Limits of Construction (LOC) prior to commencing work using fencing, flagging or other approved methods. Delineation shall be maintained for the duration of construction and shall correspond to the LOC shown on the drawings. Erosion and sediment control features (silt fence, wattles, etc) may be used to satisfy this requirement where they are installed at the LOC boundary.

2. Contractor may request deviations from the Limits of Construction but approval is not guar-anteed. Generally, the approval process once all information has been provided is up to 90 days or longer if outside agency coordination is required.

B. Equipment and Material Staging: Confine storage of materials to staging areas shown on plans.

1. Equipment and material staging areas are intended for deliveries and storage of tools and equipment, material stockpiling, construction equipment parking, construction vehicle park-ing, construction administration trailers, and similar.

2. Confine stockpiling to equipment and material staging areas. Small stockpiles within limits of construction for use in localized trenching work is acceptable.

3. Areas within the limits of construction that are not designated for equipment and material staging shall not be used for this purpose.

4. Equipment and material staging areas should not be used for construction camps including camping units, trailer complexes for living areas, private vehicle parking, and similar.

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

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

3. Provide temporary construction protection mats for all areas where construction may impact a wetland. All areas that are disturbed must be restored per Specification 01 35 05.

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

Contracting Officer (CO) and remove agreed-on roots and branches that interfere with

GRCA - 318719 01 11 00 - 5

construction. Contractor shall follow Grand Canyon vegetation guidelines related to pruning and root cutting.

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.

E. Driveways and Entrances: Keep driveways, trails, and entrances serving NPS and concessionaire premises clear and available to Government employees, and emergency vehicles at all times.

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

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

F. Construction Camp: Establishment of a camp will be permitted at WWTP, as shown on drawings and specified in 01 73 60 “Construction Camps”. Provide utilities as specified in Section 01 50

00 "Temporary Facilities and Controls". Adhere to park rules, animal deterrent policies, cleanliness policies, and return site to previous condition at completion of work.

G. Hauling Restrictions: Comply with legal load restrictions in hauling of materials. Load restrictions on park roads are identical to state load restrictions with such additional regulations as may be imposed by the Park Superintendent. Information regarding rules and regulations for vehicular traffic on park roads may be obtained from the Office of the Park Superintendent. A special permit will not relieve Contractor of liability for damage which may result from moving of equipment.

1. State Route 67 is heavily used for visitor traffic and park operations. Contractor shall not impede flow of traffic for equipment and material deliveries at any time, unless otherwise approved by the Contracting Officer.

2. Contractor shall use the North Rim park entrance gate. Contractor personnel providing iden-tification of employment with the Contractor or in a marked vehicle are not required to pay

Park entrance fees. Contractor shall not use other entrance roads into the Park.

H. State Route 67 Restrictions: Contractor shall identify jurisdictions, load restrictions, permit requirements, time and calendar restrictions as required for use of State Route 67. Contractor shall be responsible for obtaining any permits with Arizona Department of Transportation and

Coconino County as required.

1.6 PUBLIC USE OF SITE

A. Contractor shall conduct operations to ensure the least inconvenience to public.

B. Road restrictions (one lane must be passable with traffic control) may be permitted, when required, upon specific approval of Contracting Officer for a maximum of 8 hours within a single day; within park boundaries.

C. The North Rim District will be closed or limited access to visitors due to limited utilities available to the North Rim District during post fire recovery operations. Those conditions will change over time and it is unknown the exact number of visitor services that will be active during construction activities of this contract. The WWTP location is administrative and thus expects minimal impact to construction activities under this contract as visitor services change to the district.
