Construction Operating Plan and Work Schedule

Before sign installation work begins on each District, submit an operating plan to the CO that describes the location and schedule for the planned sign installations. Provide the CO an updated operating plan as often as needed to accurately represent the work schedule and locations. Schedule and conduct weekly conferences with the COR to report on progress of the previous week and the work plan for the upcoming week.

Sign Panel submittal

Sign panels must be approved by the CO. Submit examples of completed horizontal and vertical sign panels for approval by the CO. All sign panels must be of the same manufacture as the approved sign panel.

Pre-approved sign vendors include:

P.O. Box 1153 Condon, MT 59826-1153

Installation

Install route markers of the type and number at the location listed in the sign schedule. The sign schedule lists specific locations for route markers only when there is a third access point along the route. If a location is not noted on the schedule, install the route markers at the ends of the route where it intersects with other routes (do not install route markers at “dead ends”).

Place route marker as shown in Figures 3C-10 and 3C-11 in section 3C.2.9 of EM 7100-15, or as staked by the COR.

Install route marker at a mounting height and lateral distance from the road as shown in figure 3C-2 in section 3C.2.4 of EM 7100-15, or as staked by the COR. Note that vertical and horizontal route markers have different minimum placement requirements.

Install U-Channel post so that it penetrates a minimum of 2 feet into the ground. The top of the post shall not extend beyond the top of the sign panel.

Sign post lengths must be adequate to insure that the minimum depth and height requirements described above are met. While it can be assumed that these requirements can be met in most locations with an 8 foot post, some locations will require 10 or 12 foot posts. The contractor is expected to be prepared for these instances.

Install posts plumb. Posts more than 5 degrees out of plumb will not be accepted for payment.

Installation Date and Vandal Warning Labels

At the time of installation, attach installation date and vandal-warning labels as shown in Figure 3C-22 of section 3C.5 of EM 7100-15.

Removal and Disposal of Existing Route Markers

Remove and dispose of existing route markers that are in the locations specified for new route markers, unless staked otherwise by the CO. The signs and posts shall become the property of the contractor and shall be disposed of off of National Forest according to state and federal law. This work is incidental to the sign installation pay item.

Sign Installation Record/As-Built Information

Record the date of installation for each sign panel, note if an existing sign panel was removed and note any remarks on the sign panel schedule. Submit copies of the sign panel schedule with the installation notations monthly for each month the contract work is in progress. This work is incidental to the sign installation pay item.
