(a) If the Contractor fails to complete the work within the time specified in the contract, the Contractor shall pay liquidated damages to the Government in the amount of $3,461.00 for each calendar day of delay until the work is completed or accepted.

(b) If the Government terminates the Contractor's right to proceed, liquidated damages will continue to accrue until the work is completed. These liquidated damages are in addition to excess costs of repurchase under the Termination clause.

1.3 PHYSICAL DATA (APR 1984) (FAR 52.236-4)

Data and information furnished or referred to below is for the Contractor's information. The Government shall not be responsible for any interpretation of or conclusion drawn from the data or information by the Contractor.

(a) The indications of physical conditions on the drawings and in the specifications are the result of site investigations by survey, magetometer and core borings.

(b) Weather Conditions. Under ordinary conditions, the mean tidal range is about 2 feet. The height of tide is largely dependent on the force, direction, and duration of the wind. Strong northerly winds

DOCUMENT 00 73 00.01 45 Page 3 may depress the water surface as much as, and in some instances more than 2 feet below Mean Lower Low Water (MLLW), while southerly winds may raise the water surface as much as, and in some instances more than 2 feet above MLLW.

(c) Transportation Facilities. The immediate vicinity is served by railroad, highway, and deep and shallow draft channels.

The Contractor shall retain copies of all such material furnished to the Contracting Officer.

1.5 EQUIPMENT OWNERSHIP AND OPERATING EXPENSE SCHEDULE(MAR 1995)

(a) This special contract requirement does not apply to terminations.

See 52.249-5000, Basis for Settlement of Proposals, and FAR Part 49.

(b) Allowable cost for construction and marine plant and equipment in sound workable condition owned or controlled and furnished by a contractor or subcontractor at any tier shall be based on actual cost data for each piece of equipment or groups of similar serial and series for which the Government can determine both ownership and operating costs from the con-tractor's accounting records. When both ownership and operating costs cannot be determined for any piece of equipment or groups of similar serial or series equipment from the contractor's accounting records, costs for that equipment shall be based upon the applicable provisions of EP 1110-1-8, Construction Equipment Ownership and Operating Expense Schedule, Region VI. Working conditions shall be considered to be average for determining equipment rates using the schedule unless specified otherwise by the contracting officer. For equipment not included in the schedule, rates for comparable pieces of equipment may be used or a rate may be developed using the formula provided in the schedule. For forward pricing, the schedule in effect at the time of negotiations shall apply. For retroactive pricing, the schedule in effect at the time the work was performed shall apply.

DOCUMENT 00 73 00.01 45 Page 4

The contractor's provision and use of an electronic payroll processing system shall meet the following basic functional criteria: commercially available; compliant with appropriate Davis Bacon Act payroll provisions in the FAR; able to accommodate the required numbers of employees and subcontractors planned to be employed under the contract; capable of producing an Excel spreadsheet-compatible electronic output of weekly payroll records (format at http://rms.usace.army.mil/ ) for export in an Excel spreadsheet to be imported into the contractor's Quality Control System (QCS) version of Resident Management System (RMS), that in turn shall export payroll data to the Government's Resident Management System (RMS); demonstrated security of data and data entry rights; ability to

DOCUMENT 00 73 00.01 45 Page 5 produce contractor-certified electronic versions of weekly payroll data;

ability to identify erroneous entries and track the data/time of all versions of the certified Davis Bacon payrolls submitted to the government over the life of the contract; capable of generating a durable record copy, that is, a CD or DVD and PDF file record of data from the system database at end of the contract closeout.

1.3.3.3 Measurement

The material removed will be measured by cubic yard in place, by means of soundings taken before and after dredging.

The Government does not guarantee permanent access to these control points; therefore, it may be necessary for the Contractor to establish its own network of survey points from these survey points or from other U.S. Coast and Geodetic Survey (USCGS) monuments. Location and description of the horizontal control points which the Government plans to use to perform electronic surveys on the channels are available at the Port Arthur Resident Office.

The Contractor shall be responsible for establishing its own reference line to conduct hydrographic surveys and dredging operations if electronic positioning equipment is not used.
