1.2 EXISTING CONDITIONS

A. The Alaganik Slough Boat Ramp is located within the Alaganik Slough Day Use

Area, 20 miles southeast of Cordova, Alaska, within the Copper River Delta. The

Alaganik Slough Day Use Area is accessed from Cordova via a gravel road intersecting the Copper River Highway at approximately milepost 17. Cordova may be accessed by daily Alaska Airlines jet service from Anchorage and Juneau. It is also accessible by Alaska Marine Highway ferry service from Valdez and Whittier.

B. A site survey, limited geotechnical investigation, and hydraulic analysis have been conducted in support of the design of the replacement ramp. Field investigation notes and laboratory results are referenced in Section J.

C. Hydrodynamic conditions in the slough are influenced by tidal fluctuations and glacial melt, snow, and rainfall. While there is no existing tide/river stage gauge data for the site, measurements recorded during field work conducted in September 2009 indicate that daily water levels fluctuations are at least several feet. Tidal variations under extreme conditions may be considerably greater. Predictions of 50-year high water and 6-month low-water levels are shown on the Drawings. These estimates are based

Alaganik Slough Boat Ramp Replacement 01 00 00-3 on a limited hydraulic analysis, attached to these specifications per Section J, conducted to support the project design.

Contractor is not required to maintain public access to the site, however access up to the Alaganik Use Area will be allowed throughout the duration of the project to service the campsites and boardwalk. Parking for the boardwalk will be located approximately 100 yards up the Alaganik Slough Road from the boardwalk. Site access should be restricted at the entrance to the Use Area with a diversion guiding pedestrians to the boardwalk. The Slough serves as an important public access point and therefore swift construction is encouraged for the benefit of public usage.

District may approve, on a case-by-case basis, old boat ramp access for occasional administrative purposes. This access will be granted no more than 2 times per week with vehicle and trailer parking at the aforementioned parking area, not within the project site. Such access will be arranged with the contractor at least 48 hours in advance.

B. It is the contractor’s responsibility to provide mandatory site closure devices (e.g.

signs, fencing) and pedestrian diversion fencing. Additionally, the contractor is responsible for site security around the construction work area and lay-down or “bone yard” site. Any locking mechanisms at the site entrance must be coordinated with the

Contracting Officer to ensure emergency access by the USFS is maintained.

Coordinate with Contracting Officer for acceptance of layout prior to installation.

1.18 FIELD OFFICE AND STORAGE

A. Contractor shall provide its own weather-tight field office and storage, as needed to facilitate the Work. Contractor shall coordinate space for lay-down or “bone yard” area with the Contracting Officer prior to commencement of the Work. Due to the remote location of the Site, utilities (e.g., water, sewer, electricity, etc.) are unavailable, and the Contractor shall make its own arrangements, as needed, to support its temporary facilities.

1.19 POLLUTION AND ENVIRONMENTAL CONTROL

A. Contractor shall include as part of its Construction Work Plan a description of the proposed methods, means, and facilities to prevent contamination of soil, water, and atmosphere from discharge of noxious, toxic substances, and pollutants produced by construction operations.

B. Contractor shall be responsible for preparing a Stormwater Pollution Prevention Plan

(SWPPP) to address provisions of EPA’s General Permit for Construction Activities, as administered by the Alaska Department of Environmental Conservation.

Contractor is responsible for selecting, and describing the appropriate best management practices (BMPs) to protect stormwater discharge quality at the construction site. At a minimum, silt fencing protecting the Slough will be required.

Contractor shall effectively implement selected BMPs to ensure compliance with

Alaganik Slough Boat Ramp Replacement 01 00 00-9 permit conditions. Contractor shall provide a completed, signed original of the Notice of Intent and Notice of Termination in accordance with permit conditions.

C. Contractor shall include as part of its Construction Work Plan, an Erosion and

Sediment Control Plan.

D. Contractor shall comply with all applicable environmental, erosion, and water quality control regulations and permit requirements.

C. Pay Items

Items will be measured and paid per the Schedule of Pay Items and Measurement and

Payment Terms below. The following definitions shall apply:

“Each” or “EA” – These quantities denote one complete unit, which may consist of one or more parts.

“Lump Sum Quantities” or “LS” or “LSQ” - These quantities denote one complete unit of work as required by or described in the contract, including necessary materials, equipment, and labor needed to complete the job. They will not be measured.

“Linear Foot” or “LF” – Measurement is on a plane parallel to the surface being measured.

“Square Foot,” “SF,” “Square Yard,” or “SY” - Measurement is on a plane parallel to the surface being measured, in either square feet or square yards.

“Cubic Yard” or “CY” - Measurement is computed by the average-end area method from measurements made longitudinally along a centerline or other reference line.

All CY quantities are measured in-place and compacted.

“Designed Quantities” or “DQ” - These quantities denote the final number or units to be paid for under the terms of the contract. They are based upon the original design data available prior to advertising the project. Original design data include the preliminary survey information, design assumptions, calculations, drawings, and the presentation in the contract. Changes in the number of units SHOWN in the

SCHEDULE OF ITEMS may be authorized under any of the following conditions:

(1) As a result of changes in the work authorized by the Contracting Officer.

(2) As a result of the Contracting Officer determining that errors exist in the original design that cause a pay item quantity to change by 15 percent or more.

(3) As a result of the Contractor submitting to the Contracting Officer a written request showing evidence of errors in the original design that cause a pay item quantity to change by 15 percent or more. The evidence must be verifiable and consist of calculations, drawings, or other data that show how the designed quantity is believed to be in error.

“Actual Quantities” or “AQ” - These quantities are determined from measurement of completed work. Payment is governed by FAR 52.211-18.
