SPECIAL CONTRACT REQUIREMENTS, STANDARD

AMENDMENT NO. 0002

PART 1 GENERAL

1.1 COMMENCEMENT, PROSECUTION, AND COMPLETION OF WORK (APR 1984) (FAR

52.211-10) (AM#2)

The Contractor shall be required to:

(a) Commence work under this contract within 10 calendar days after the date the Contractor receives the Notice to Proceed;

(b) Prosecute the work diligently, and

(c) Complete the entire work ready for use not later than 420 467 calendar days after the date the Contractor receives the Notice to Proceed. The time stated for completion shall include final cleanup of the premises.

1.2 LIQUIDATED DAMAGES - CONSTRUCTION (SEP 2000) (FAR 52.211-12)

(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 $3,850.00 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 surveys and core borings.

(b) Weather Conditions. Under ordinary conditions, the mean tidal range is about 1.5 feet. The height of tide is largely dependent on the force, direction, and duration of the wind. Strong northerly winds may depress the water surface as much as, and in some instances more than 0.5 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 highway, and shallow draft channels. The channel is accessible by

DOCUMENT 00 73 00.00 45 Page 3 water from Houston Ship Channel. Placements areas 1 and 2, and Ijams Lake can be reach from Cedar Bayou. The Government has no ROW to access the placement areas and Ijams Lake by land from the public roadways.

(d) Other Information. Channel traffic consists of small boats of various sizes, and tows consisting of a tug and one or more barges.

1.4 WARRANTY OF CONSTRUCTION (MAR 1994) (FAR 52.246-21)

(a) In addition to any other warranties in this contract, the Contractor warrants, except as provided in paragraph (i) of this clause, that work performed under this contract conforms to the contract requirements and is free of any defect in equipment, material, or design furnished, or workmanship performed by the Contractor or any subcontractor or supplier at any tier.

(b) This warranty shall continue for a period of 1 year from the date of final acceptance of the work. If the Government takes possession of any part of the work before final acceptance, this warranty shall continue for a period of 1 year from the date the Government takes possession.

(c) The Contractor shall remedy at the Contractor's expense any failure to conform, or any defect. In addition, the Contractor shall remedy at the Contractor's expense any damage to Government-owned or controlled real or personal property, when that damage is the result of --

(1) The Contractor's failure to conform to contract requirements;

or

(2) Any defect of equipment, material, workmanship, or design furnished.

(d) The Contractor shall restore any work damaged in fulfilling the terms and conditions of this clause. The Contractor's warranty with respect to work repaired or replaced will run for 1 year from the date of repair or replacement.

(e) The Contracting Officer shall notify the Contractor, in writing, within a reasonable time after the discovery of any failure, defect, or damage.

(f) If the Contractor fails to remedy any failure, defect, or damage within a reasonable time after receipt of notice, the Government shall have the right to replace, repair, or otherwise remedy the failure, defect, or damage at the Contractor's expense.

(g) With respect to all warranties, express or implied, from subcontractors, manufacturers, or suppliers for work performed and materials furnished under this contract, the Contractor shall--

(1) Obtain all warranties that would be given in normal commercial practice;

(2) Require all warranties to be executed, in writing, for the benefit of the Government, if directed by the Contracting Officer;

and

DOCUMENT 00 73 00.00 45 Page 4

(3) Enforce all warranties for the benefit of the Government, if directed by the Contracting Officer.

(h) In the event the Contractor's warranty under paragraph (b) of this clause has expired, the Government may bring suit at its expense to enforce a subcontractor's manufacturer's, or supplier's warranty.

(i) Unless a defect is caused by the negligence of the Contractor or subcontractor or supplier at any tier, the Contractor shall not be liable for the repair of any defects of material or design furnished by the Government nor for the repair of any damage that results from any defect in Government-furnished material or design.

(j) This warranty shall not limit the Government's rights under the Inspection and Acceptance Clause of this contract with respect to latent defects, gross mistakes, or fraud.

(k) Defects in design or manufacture of equipment specified by the Government on a "brand name and model" basis, shall not be included in this warranty. In this event, the Contractor shall require any subcontractors, manufacturers, or suppliers thereof to execute their warranties, in writing, directly to the Government.

1.5 ESTABLISHING THE COST FOR CONSTRUCTION EQUIPMENT(FAR 31.105(D)(2)i)

This special contract requirement does not apply to terminations. See 52.249-5000, Basis for Settlement of Proposals, and FAR Part 49.

Allowable ownership and operating costs shall be determined as follows:

(a) Actual cost data shall be used when such data can be determined for both ownership and operations costs for each piece of equipment, or groups of similar serial or series equipment, from the contractor’s accounting records. When such costs cannot be so determined, the contracting agency may specify the use of a particular schedule of predetermined rates or any part thereof to determine ownership and operating costs of construction equipment. However, costs otherwise unallowable under this part shall not become allowable through the use of any schedule (see FAR 31.109(c)). For example, schedules need to be adjusted for Government contract costing purposes if they are based on replacement cost, include unallowable interest costs, or use improper cost of money rates or computations. Contracting officers should review the computations and factors included within the specified schedule and ensure that unallowable or unacceptably computed factors are not allowed in cost submissions.

b) Predetermined schedules of construction equipment use rates (e.g., the Construction Equipment Ownership and Operating Expense Schedule, published by the U.S. Army Corps of Engineers, industry sponsored construction equipment cost guides, or commercially published schedules of construction equipment use cost) provide average ownership and operating rates for construction equipment. The allowance for operating costs may include costs for such items as fuel, filters, oil, and grease; servicing, repairs, and maintenance;

and tire wear and repair. Costs of labor, mobilization, demobilization, overhead, and profit are generally not reflected in schedules, and separate consideration may be necessar.

DOCUMENT 00 73 00.00 45 Page 5

(c) When a schedule of predetermined use rates for construction equipment is used to determine direct costs, all costs of equipment that are included in the cost allowances provided by the schedule shall be identified and eliminated from the contractor’s other direct and indirect costs charged to the contract. If the contractor’s accounting system provides for site or home office overhead allocations, all costs which are included in the equipment allowances may need to be included in any cost input base before computing the contractor’s overhead rate. In periods of suspension of work pursuant to a contract clause, the allowance for equipment ownership shall not exceed an amount for standby cost as determined by the schedule or contract provision.

1.6 CFR PART 126 HUBZONE PROGRAM - SUBPART G - CONTRACT PERFORMANCE

REQUIREMENT

Sec. 126.700 What are the performance of work requirements for HUBZone contracts?

(a) A prime contractor receiving an award as a qualified HUBZone SBC must meet the performance of work requirements set forth in Sec.

125.6(c) of this chapter.

(b) In addition to the requirements set forth in Sec. 125.6(c), one or more qualified HUBZone SBCs must spend at least 50 percent of the cost of the contract incurred for personnel on its own employees or employees of other qualified HUBZone SBCs.

(1) A qualified HUBZone SBC prime contractor receiving a HUBZone contract for general construction may meet this requirement itself by expending at least 50 percent of the cost of the contract incurred for personnel on its employees or it may subcontract at least 35 percent of the cost of the contract performance incurred for personnel to one or more qualified HUBZone SBCs. A qualified HUBZone SBC prime contractor may not, however, subcontract more than 50 percent of the cost of the contract incurred for personnel to non-qualified HUBZone SBCs.
