3. SCOPE OF WORK

The work to be done under this Contract, on US101 (Oregon Coast Highway) consists of supplying the materials, equipment, labor and incidentals required to perform the following tasks as described below and in the Contract specifications:

• Provide Work Zone Traffic Control at the work location from the Oregon Temporary Traffic Control Handbook (OTTCH 2011)

• Remove the existing 12” CONC pipe, 58’ length, 5.5’ depth.

• Install a new 18” HDPE pipe at the same grade and skew. (Grade may be minorly adjusted in the field as directed. Possibly raised max of 6” to improve flow)

• Construction means and methods are up to the contractor, but it is anticipated that the work will be completed in half sections over two nights.

• Utilities are expected to be in the area. The Contractor should contact 811 and plan work accordingly.

• In late summer this crossing carries no flow but may still contain damp soils. In the event there is water present, bid item 3 is included as a contingency item to pay for some sump pumps in the even they’re needed.

• The project must be completed in the dry and during the In Water Work Window of July 1 – September 15.

• Meet with the Agency Biologist, Resource Representative, Engineer, and inspector on site, before moving equipment on-site or beginning any work, to ensure that all parties understand the locations of sensitive biological sites and the measures that are required to be taken to protect them.

• Pipe installation is expected to follow standard drawing RD300 for pipe excavation and backfill. Trench backfill to be Class “B” and extend flush to wearing surface grade. The Agency will perform trench repair paving and striping.

• Perform additional and incidental work as called for by the Contract plans and specifications and as directed.

(1) General Requirements:

• Do not install fish ladders (for example: pool and weirs, vertical slots, fishways) or fish trapping systems.

• Do not apply surface fertilizer within 50 feet of any stream channel.

Use heavy equipment as follows:

• Choice of equipment must have the least adverse effects on the environment (for example: minimally sized, low ground pressure).

• Secure absorbent material around all stationary power equipment (for example: generators, cranes, drilling equipment) operated within 150 feet of wetlands, waters of the State, waters of the U. S., drainage ditches, or water quality facilities to prevent leaks, unless suitable containment is provided to prevent spills from entering waters of the State or waters of the U.S.

• Do not cross directly through a stream for construction access, unless shown or approved. If shown or approved, cross perpendicular to the stream and do not block stream flow. When a crossing is no longer needed, completely remove the crossing and restore the soils and vegetation to the original condition.

• Store fuel and maintain all equipment in staging areas that are at least 150 feet away from any waters of the State, waters of the U.S., or storm inlet or on an impervious surface that is isolated from any waters of the State, waters of the U.S., or storm inlet.

• If temporary access roads are needed within 150 feet of any body of water, use existing routes unless new routes are shown or approved.

• Before beginning work on temporary access routes that are not shown, submit a proposal to the Engineer for approval.

(2) Work Area Isolation - Provide work isolation according to Section 00245. Provide safe passage around or through the isolated work area for adult and juvenile migratory fish unless passage did not previously exist.

(3) Water Intake Screening - Install, operate, and maintain fish screens on each water intake used for project construction, including pumps used to isolate an in-water work area. When drawing or pumping water from any stream, protect fish by equipping intakes with screens having a minimum 27 percent open area and meeting the following requirements:

• Perforated plate openings shall be 3/32 inch or smaller.

• Mesh or woven wire screen openings shall be 3/32 inch or smaller in the narrowest direction.

• Profile bar screen or wedge wire openings shall be 1/16 inch or smaller in the narrow direction.

(9) Treated Wood - Treated wood includes any wood treated with any pesticide or wood preservatives. Do not use lumber, pilings, or other wood products that are treated or preserved with pesticidal compounds below the ordinary high water (OHW) or as part of an in-water or over-water structure, except as described below:

• Store treated wood shipped to the Project out of contact with standing water and wet soil, and protected from precipitation.

• Visually inspect each load and piece of treated wood. Reject for use in or above aquatic environments if visible residues, bleeding of preservative, preservative-saturated sawdust, contaminated soil, or other matter is present.

• Use pre-fabrication to the extent feasible. When field fabrication is necessary, all cutting and drilling of treated wood, and field preservative treatment of wood exposed by cutting and drilling, shall occur above the OHW. Use tarps, plastic tubs, or similar devices to contain the bulk of any fabrication debris, and wipe off any excess field preservative.

• All treated wood structures, including pilings, shall have design features to avoid or minimize impacts and abrasion by livestock, pedestrians, vehicles, vessels, and floats.

• Treated wood may be used to construct a bridge, over-water structure or an in-water structure, with the exception of the work containment system, provided that all surfaces exposed to leaching by precipitation, overtopping waves, or submersion are coated with a water-proof seal or barrier are maintained. Apply and contain coatings and paint-on field treatment to prevent contamination.

Surfaces that are not exposed to precipitation or wave attack, such as parts of a timber bridge completely covered by the bridge deck, are exempt from this requirement.

• During demolition of treated wood, ensure that no treated wood debris falls into the water. If treated wood debris does fall into the water, remove it immediately.

• Store removed treated wood debris in appropriate dry storage areas, at least 150 feet away from the regulated work area.
