Only rock that can be removed by hand or bar will be scaled; areas that can be mitigated by bolting, wire mesh netting, or other techniques will be so identified and treated.

P a g e | 21 of 32

Hazardous conditions the contractor may encounter may include, but are not limited to, specific low and high temperature extremes; possible high winds; and animals such as snakes.

Close coordination and communication are required for all the above tasks by both Reclamation and the contractor. All tasks shall be monitored by the assigned Reclamation Representative and coordinated with the operations and maintenance staff of the identified facility. The Government reserves the right to evaluate the resulting corrective actions, for a period of up to 30 days after completion, prior to acceptance of task work and approval of payment. The purpose of such evaluation is to verify that the corrective actions are stable and enduring, and that no unforeseen impacts exist that may require additional efforts by the Contractor. All tasks shall be documented with complete reports, to include documentation of changes and update and maintenance documentation.

Since the IDIQ allows for fixed price, time and material and labor hour orders; subsequent changes to awarded task orders may be fixed price, time and material, or labor hour.

Payment for work performed under time-and material and labor-hour changes will include actual costs plus overhead and profit established at the time of contract award.

4.3 TYPICAL ROCKFALL MITIGATION ACTIVITIES

Typical mitigation measures anticipated for most task orders of this contract include but are not limited to the following:

A. Moving or Removal (Scaling) of Rock

This work includes the rope access, inspection, planning, reporting of findings to the Government and scaling of rock by hand, bar, or compressed air. The Government will provide an inspector/geologist to establish the amount of work required in each area after considering the recommendations of the contractor’s representative. There is no intent of removing rock that does not pose a threat to the public, personnel, or the facilities. Only rock that can be removed by hand or bar shall be scaled. Rock that may pose a future threat or that requires removal beyond the scope of this contract shall be identified and reported with recommendations to the Government for possible future contract work. Scaling large rock onto project sites will be subject to additional approvals by the Government.

1. Rock fall mitigation activities that involve rope work shall NOT be performed in the Visitor Center area between 9 a.m. and 6 p.m. See Figure 1 for Visitor Center Areas. The Contractor may provide temporary lighting to allow scaling during an overnight shift. The Contractor must be off rope by 9 a.m. The Contractor will have procedures in place to allow for the safe passage of vehicular and pedestrian traffic from 7:30 a. m. to 9 a.m. and any temporary protective measures or fallen rock that would impede or obstruct access must be removed to allow for safe passage.

2. Work performed on the slopes above the powerhouses may be performed at any time provided the Contractor informs the Lower Colorado Dams Office and obtains permission.
