1.3.2 Subsurface Investigations

Geotechnical investigations have been undertaken, and logs of those investigations are included in APPENDIX A – SEDIMENT CHARACTERIZATION DATA of these specifications.

1.3.3 Environmental Investigations

Previously, AWI operated a wood-treating facility at the site using both creosote and pentachlorophenol (PCP). The site was contaminated from the treatment operation, storage of treated wood, and disposal of wastes. In addition, the Navy leased part of the property from AWI and disposed of wastes on site, including used abrasive blast media and sludge from the production of acetylene.

Environmental investigations have been undertaken to characterize the material to be dredged and logs of those investigations are included in APPENDIX A – SEDIMENT CHARACTERIZATION DATA of these specifications.

1.3.4 Debris-Related Information

Investigations to characterize potential debris within the project footprint have been undertaken and are included in APPENDIX B – POTENTIAL DEBRIS INFORMATION of these specifications. The information included in APPENDIX B includes:

• Photographic Log of Existing Debris and Recent Debris Removal Efforts -includes a photograph of typical debris that was removed from the Wyckoff Inlet in Spring 2013 and photos of remaining timber pilings in Wyckoff Inlet to be removed.

• An Archaeological and Historical Records Review of the Atlantic Wood Industries Superfund Site, Portsmouth, Virginia (PCI 2009) — shows the historical location of two sunken barges in the project area. Both sunken barges have been removed to upland areas; some minimal residual debris may remain on the outside (east of) and inside (west of) the Offshore Sheet Pile Wall. The PCI report also provides historical information on the past structures in the project area that were demolished or collapsed and are now a source of potential debris. As indicated on the Drawings, much of this debris has been removed by recent remedial actions, including removing timber pilings from areas accessible by barge. Some timber pilings remain and can be seen above the water surface in shallow areas of the Wyckoff Inlet, behind the Offshore Sheet Pile Wall (OSPW).

Section 01 11 00 Page 4 http://www.epa.gov/reg3hwmd/npl/VAD990710410/rod/rod2007.htm

• Wyckoff Inlet Aerial Photograph (included in PCI 2009 report) — shows the location of previous pier and wharf structures in the project area. Some concrete piers have been removed from the site and some wooden and concrete piles have been removed; however, some piers and piles remain.

The Contractor should anticipate encountering some remnant pile fragments in areas below the mud line.

• PER Property (Formerly PPIC) Debris Investigation (EA 2009) — a probing survey was performed along the PER shoreline where a dilapidated concrete and stone wharf structure existed. Most of the concrete and stone has been removed along the shoreline, but some remnants may exist offshore.

The survey indicated where obstructions were encountered.

Additional debris-related information is provided on the Drawings.

More information about how debris shall be managed is included in Section

35 20 23, DREDGING.

c. Tide Current Tables, Atlantic Coast of North America, published annually by the National Ocean Service.

d. Local Notice of Mariners, published by the Fifth U.S. Coast Guard District and the broadcast local notice to mariners.

1.4.2 Site Related Weather Conditions

The location of the work area is in the Southern Branch of the Elizabeth River; accordingly, the Contractor shall anticipate that severe weather conditions may occasionally interfere with the progress of work. The area is tidal with a mean range of tide of approximately 2.86 ft at Money Point (approximately 2 miles upriver/south of the AWI site); however, currents are normally not of a sufficient velocity to interfere with operations. Complete weather forecasts, records, and reports may be obtained from the National Weather Service in Wakefield, Virginia, telephone (757) 899-4200, menu selection service or operator assisted as applicable. The Contractor shall satisfy himself as to the hazards likely to arise from the weather conditions during work period.

1.4.3 Obstructions of Channel

The Government will not undertake to keep the area of channels free from vessels or other obstructions, except to the extent of such regulations, if any, as may be prescribed by the Secretary of the Army, in accordance with the provisions of Section 7 of the River and Harbor Act, approved 3 August 1917.

The Contractor will be required to conduct the work in such manner as to obstruct navigation as little as possible, and in case the Contractor’s plant so obstructs the channel as to make difficult or endanger the passage of vessels, said plant shall be promptly moved (in less than 2 hours) on the approach of any vessel to such an extent as may be necessary to afford a practicable passage. Following safe passage of the commercial ship, the Contractor may re-establish his/her equipment in the work zone. Upon the completion of the work, the Contractor shall promptly remove his plant, including ranges, buoys, piles, and other marks placed by him under this Contract in navigable water or on shore.

1.4.4 Responsibility

The Contractor shall hold and save harmless the United States, its officers, and employees from all claims that may arise as a result of the Contractor's negligence in connection with the work performed under the Contract, from noncompliance by the Contractor with the provisions of the contract drawings and specifications, or from the instruction of the Contracting Officer.

Section 01 14 00 Page 3

1.4.5 Condition of Work Area

The Drawings show the condition of the work area at the time of the most recent survey. The Government has knowledge of artificial obstructions in the work area and has identified known obstructions; however, the work area may contain trash, debris, and other obstructions not shown on the Drawings.

1.4.6 Channel Traffic

Local channel traffic consists of a wide variety of types and sizes of vessels, including large deep-draft commercial bulk carriers, tankers, container vessels, Naval vessels, shallow and medium draft commercial seafood vessels, barges, tugs, pleasure crafts, and various other crafts. The Contractor shall expect that the vessel traffic will cause periodic delays and interruptions of operations while working near the channel.

The U.S. Coast Guard Captain of the Port of Hampton Roads (757-483-8565) can provide lists of scheduled commercial ship traffic, which typically includes scheduled traffic 1-2 days in advance. The Contractor is responsible for obtaining this information to schedule the Work. The Contractor shall conduct daily coordination while working in the channel to discuss anticipated traffic.

1.4.7 Oyster Grounds

There are no known oyster grounds in the work area; however, some exist across the River from the site along the eastern bank.

1.4.8 Utility Crossings

There is a known, abandoned fiber optic line beneath the dredging prism. The Contractor is unlikely to encounter the line during dredging, but it can be managed as debris if it is encountered and pieces are pulled up by the dredging equipment.

1.5 PUMPING OF BILGES

Contractors are warned that pumping oil or bilge water containing oil into navigable waters, or into areas which would permit the oil to flow into such waters, is prohibited by Section 13 of the River and Harbor Act of 1899, approved 3 March 1899 (30 Stat. 1152; 33 U.S.C. 407). Violation of this prohibition is subject to the penalties under the referenced Acts.

1.6 FUEL TRANSFER OPERATIONS

In accordance with U.S. Coast Guard regulations 33 CFR 156.120, couplings used in fuel oil transfer operations on any vessel with a capacity of 250 or more barrels of oil shall be either a bolted or full-threaded connection; or a quick-connect coupling approved by the Commandant; or an automatic back-pressure shutoff nozzle used to fuel the vessel. An executed fuel oil transfer (Declaration) form signed by the tanker operator shall be submitted to the Contracting Officer for each refueling operation.

Section 01 14 00 Page 4

1.7 PUMPING OF HEADS

Pumping treated or untreated sewage into navigable waters, or into areas which would permit sewage to flow into such water is prohibited.

1.8 INSPECTION

1.8.1 General Inspection Requirements

The presence of the Contracting Officer, Contracting Officer’s Representative (COR) or any Government construction representative shall not relieve the Contractor of responsibility for the proper execution of the work in accordance with the specifications. The Contractor will be required to furnish, on the request of the Contracting Officer, COR or any construction representative, the use of such boats, boatmen, laborers, and material forming a part of the ordinary and usual equipment and crew of the marine plant as may be necessary in inspecting and supervising the work.

1.13 PROFIT

1.13.1 Weighted Guidelines

Weighted guidelines method of determining profit shall be used on any equitable adjustment change order or modification issued under this Contract.

The profit factors, expressed as a percent, shall be as follows:

Factor Rate Weight Value

Degree of Risk 20 Relative difficulty of work 15 Size of Job 15 Period of performance 15 Contractor's investment 5 Assistance by Government 5 Subcontracting 25

1.13.2 Values

Based on the circumstances of each procurement action, each of the above factors shall be weighted from .03 to .12 as indicated below. The value shall be obtained by multiplying the rate by the weight. The value column when totaled indicates the fair and reasonable profit percentage under the circumstances of the particular procurement.

1.13.2.1 Degree of Risk

Where the work involves no risk or the degree of risk is very small, the weighting should be .03; as the degree of risk increases, the weighting should be increased up to a maximum of .12. Lump sum items will have, generally, a higher weighted value than the unit price items for which quantities are provided. Other things to consider: the portion of the work

Section 01 14 00 Page 7 to be conducted by subcontractors, nature of work, where work is to be performed, reasonableness of negotiated costs, amount of labor included in costs, and whether the negotiation is before or after performance of work.

1.13.2.2 Relative Difficulty of Work

If the work is most difficult and complex, the weighting should be .12 and should be proportionally reduced to .03 on the simplest jobs. This factor is tied in some extent with the degree of risk. Some things to consider: the nature of work, by whom it is done, where, and what is the time schedule.

1.13.2.3 Size of Job

All work not in excess of $100,000 shall be weighted at .12. Work estimated between $100,000 and $5,000,000 shall be proportionally weighted from .12 to .05. Work from $5,000,000 to $10,000,000 shall be weighted at .04. Work in excess of $10,000,000 shall be weighted at .03.

1.13.2.4 Periods of Performance

Jobs in excess of 24 months are to be weighted at .12. Jobs of lesser duration are to be proportionally weighted to a minimum of .03 for jobs not exceed 30 days. No weight where additional time is not required.

1.13.2.5 Contractor's Investment

To be weighted from .03 to .12 on the basis of below average, average, and above average. Things to consider: amount of subcontracting, mobilization payment item, Government furnished property, equipment and facilities, and expediting assistance.

1.13.2.6 Assistance by Government

To be weighted from .12 to .03 on the basis of average to above average.

Things to consider: use of Government owned property, equipment and facilities, and expediting assistance.

1.13.2.7 Subcontracting

Shall be weighted inversely proportional to the amount of subcontracting.

Where 80 percent or more of the work is to be subcontracted, the weighting is to be .03 and such weighting proportionally increased to .12 where all the work is performed by the Contractor's own forces.
