CONSTRUCTION NOTES

GENERAL

1. Refer to the Standard Specifications for Construction of Roads and Bridges on Federal Highway

Projects (FP-14).

SECTION 156 PUBLIC TRAFFIC

1. Project roads shall be kept open to all traffic, with minimal delays. If a full road closure is required, the maximum time per closure event shall be 1 hour in duration.

2. The Contractor shall submit a temporary traffic control plan to the CO for approval. Work shall not commence until the temporary traffic control plan is approved.

3. All construction signing shall be completed and approved prior to the beginning of construction.

4. All construction signing shall conform to the Manual on Uniform Traffic Control Devices (MUTCD).

SECTION 201

1. Clearing and Grubbing shall be performed in a manner that provides a minimum of ground disturbance, but yet is substantial enough to perform the utility trench work.

SECTION 204

1. Embankment material shall be used in cases where existing material is too large to be placed adjacent to the buried power line, and/or when large boulders are excavated from trenching operations, and other materials will be needed to complete backfilling operations.

2. A US Forest Service (USFS) owned, and developed borrow source is located approximately 5 miles from the project site. A pit plan of operations shall be submitted prior to commencement of work, subject to approval by USFS.

3. Measurement and payment of borrow excavation quantities shall be based upon before and after surveys performed by the USFS. Embankment construction quantities shall be based upon measured excavation quantities, with no adjustment for shrink or swell.

4. Borrow haul shall be considered incidental to this pay item.

5. Borrow material shall conform to the gradation requirements set forth in the specifications. No additional payment shall be made for processing of borrow material.

SECTION 625

1. Section 625 pay items shall not be awarded if Optional items 636(11)c & 636(11)d are awarded.

SECTION 636

1. Trench depth shall be a minimum of 4' deep to the top of the cable-in-conduit (to be placed by

Utility). No additional payment will be made for excessive depth trenching.

2. Depending upon trench conditions, borrow embankment bedding may be required to be placed before the cable-in-conduit is placed. Borrow bedding shall be paid under pay items 204(12) and

204(15).

3. Trenching operations shall be performed in coordination with the Utility, as to minimize the amount of open trench at the end of each work day, and all open trench shall be marked and fenced off during non-working days, such as weekends.

4. Contractor shall backfill trench after Utility has installed the cable-in-conduit. Backfill material shall meet the requirements for maximum size per the detail drawings, and shall be compacted to 100% of in-situ materials outside of roadways, and to 95% of Standard Proctor for areas under roadways.

Backfilling and compaction of the trench shall be considered incidental to pay items 636(11)a &

636(11)b.

5. Several ephemeral stream crossings exist along the proposed route. If trenching were to be performed while runoff conditions exist, the Contractor shall divert the runoff in accordance with the

Wyoming Forestry Best Management Practices guidelines.

6. OPTIONAL ITEMS 636(11)c - Vibratory plowing of the cable-in-conduit. Cable-in-conduit shall be supplied by the Utility, and is 2.4" OD, by Okonite. Location of line shall be in the center of the roadway along the proposed alignment. At locations where the new power line and existing drainage culverts will cross, the Contractor shall excavate the existing culverts to remove a portion of the culvert to permit power line installation, and then subsequently splice repair the culvert with approved coupling devices. Backfilling of these splice locations shall meet the requirements of in-roadway trenching shown on Sheet 05. Culvert splicing work shall be considered incidental to the

Optional pay item. One splice location will be needed outside of the roadway, and shall be 5' wide, by 5' long, by 14" deep. The excavation, leveling, and base compaction of the splice box hole shall be incidental to the Optional pay item.
