SOIL BORING DATA

PART 1 GENERAL

1.1 Soil Classification

The soil was visually classified in the field according to the "Unified Soil Classification System" and described utilizing the "Burmister's Method of Material Proportions". While it is believed that borings accurately indicate subsurface conditions for boring locations on the date taken, the Government assumes no responsibility for actual conditions which may be encountered in execution of Contract. Should the Contractor rely, for any purpose, upon the accuracy or completeness of said borings, or log thereof, he does so at his own risk. The geotechnical report, including soil boring drilling logs and data, is shown in the 2018 Schnabel Geotechnical Report at the end of the specifications. Soil borings shown in Appendix A, Laboratory Analysis is shown in Appendix B, and Beach Laboratory Analysis data is shown in Appendix C of the Geotechnical Report .

All samples contained in the appendices at the end of th e specifications were obtained on various dates as designated on the respective boring.

Geotechnical analysis data is available for review at Norfolk District, 803 Front Street, Norfolk, VA 23510 (Attention: Matt McKeehan telephone 757-201-7172).

1.2 Sampling Method

All boring samples were obtained utilizing a vibracore sampler.

1.3 Soil Consistency Determination

1.19 HISTORICAL AND ARCHAEOLOGICAL FINDS

Federal legislation provides for the protection, preservation, and

SECTION 01 14 00 Page 12 collection of scientific, prehistoric, historic, and archaeological data, including relics and specimens that might otherwise be lost as a result of any Federal construction project. Should the Contractor, or any of the Contractor's employees, or parties operating or associated with the Contractor, in the performance of this contract discover evidence of possible scientific, prehistoric, historic, or archaeological data, the Contractor shall immediately cease work at that location, and notify the Contracting Officer, giving the location and nature of the findings. The Contractor shall forward written confirmation to the Contracting Officer as directed. The Contracting Officer shall notify the districts' Archaeologist and the State historic preservation office if any resources are discovered. The Contractor shall exercise care so as not to disturb or damage shipwrecks, artifacts or fossils uncovered during excavation, dredging and material placement operations, and shall provide such cooperation and assistance as may be necessary to preserve the findings for removal or other disposition. Any person who, without written permission, injures, destroys, excavates, appropriates, moves or removes any historic or prehistoric artifact, object of antiquity, or archaeological resource is subject to arrest and penalty of law. Where appropriate by reason of discovery, the Contracting Officer may order delays in the time of performance or changes in the work, or both. If such delays or changes are ordered, an equitable adjustment will be made in accordance with the applicable clauses of the contract.

1.19.1 Avoidance of Historic Resources

Not less than thirty calendar days from the start of dredging operations, the Contractor shall perform a marine remote sensing survey at the site(s) of any booster(s) or Scott's buoy/anchored pumpout buoy locations to ensure that potential historic resources are not located within his work area. If potential resources are identified during the survey, Contractor shall immediately notify the Contracting Officer's Representative, giving the location and nature of the findings. Contractor shall relocate his construction areas and establish a 100-ft buffer around the discovery. Do not anchor or spud in any such historic-resource, buffer zone nor disturb the buffer area in any way.

The proposed revised buoy site or booster location shall be surveyed to ensure no historic resources are within any revised work area.

1.20 PROFIT

1.20.1 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

SECTION 01 14 00 Page 13

1.20.2 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.

1.20.2.1 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 to be done 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.

1.20.2.2 Relative Difficulty of Work

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

1.20.2.3 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 proportionately weighted from .12 to .05.

1.20.2.4 Periods of Performance

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

1.20.2.5 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.

1.20.2.6 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.

1.20.2.7 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 proportionately increased to .12 where all the work is performed by the Contractor's own forces.
