3. Method of surveillance will be 100% inspection by the QAP. Surveillance will be performed as specified in the Service Delivery Summary (SDS) in paragraph 5 below.

4. Where appropriate, methods for administering and evaluating services not included in the Service Delivery Summary are to be developed by the QAP.

a. The government retains the right to inspect required tasks not shown on the Service Delivery Summary. Inspection of these services will be in the same general manner as SDS items. The results of these inspections shall be documented. Any results that require minor corrective actions, the government inspector shall discuss the deficiencies with the appropriate shipyard personnel. Any major deficiency shall be provided to the contracting officer for action.

b. The following non-SDS items may be observed periodically during the contract period.

* Employees identification badges if working on any repair work for the Dredge Wheeler whether on board or on the drydock.

INSPECTION AND ACCEPTANCE

E-l GENERAL INSPECTION AND TESTS - QUALITY CONTROL AND QUALITY ASSURANCE

a. The Contractor shall provide and maintain an inspection (Quality Control) program covering all work specified in the Contract utilizing a designated organizational element and personnel not involved in the work. The Contractor shall perform, or have performed, all inspections and tests required to substantiate that the supplies and services submitted to the Government for acceptance conform to the drawings, work statement and contract requirements herein.

b. The Contractor's inspection system shall be documented, and the records shall be available for review prior to award of the Contract and throughout the life of the contract. For each work statement item, the Contractor shall determine and record the inspections and tests to be accomplished, the observations made, any deficiencies found and the corrective action taken.

In addition to the inspections and tests which the Contractor is to perform to assure contract performance and quality of product, all inspections and tests specified in the work statement will also be included in the inspection system.

c. Quality Assurance (QA) inspections will be performed by Government personnel at those stages of work necessary to determine conformance with the contract requirements. Generally a QA inspection will be made for each item of work, including growth work, to verify that the work has been completed as specified and the item is ready for testing. In addition, QA inspections will also be made for those initial and in-progress inspections specified in the various specification items. Required inspection points are denoted in the work statement with the words "INSPECTION POINT" in bold letters.

d. The Contractor shall submit after award the quality control assurance program to be utilized to assure the Government that all work conforms to the requirements of the work statement.

The program shall include a list and schedule of all inspections to be made, a list of the Contractor's personnel who will be planning, coordinating, performing or witnessing the inspections and tests and the form to document procedures to be followed by Contractor and Government personnel. A copy of the forms to be used to record the inspections made, the deficiencies noted and corrective actions taken will also be included.

e. The Contractor will notify the Contracting Officer Representative, in writing, at least 12 hours in advance of the time and date of each inspection and test. If the Government Inspector is not present at the scheduled time, the Contractor will proceed with the inspection or test and document the results as required herein. If the scheduled inspection is to verify completion of an item of work, the notice will include a signed certification that all materials and workmanship meet all requirements of the work statement, that all work has been satisfactorily completed and the item is ready for inspection.

f. Any defects in workmanship or material will be remedied by the Contractor at no additional cost to the Government, and fully re-tested. Witnessing tests and inspections by the Government Inspector and signing of related documentation does not constitute acceptance of the item, and does not relieve the Contractor of the responsibility of assuring that the work and material conform to the requirements of the work statement.

g. A copy of the inspection documentation, duly signed by the Contractor and Government Inspectors (including U.S. Coast Guard and ABS Inspectors, when applicable) will be furnished to the Contracting Officer Representative within 48 hours after each inspection and/or test.

Payment for each item, including growth work, will be contingent on receipt by the Contracting Officer Representative of the Completion Report recording the specific work accomplished, date(s) work was done and the shop or craft performing the work. No item shall be considered 100 percent complete on the progress report, until this report, signed by the Government Inspector, has been submitted to the Contracting Officer Representative.

h. Work subcontracted and performed away from the shipyard is also covered by this inspection system. The prime Contractor cannot delegate the authority to witness or perform, and sign for tests and inspections conducted away from the shipyard, without written approval of the Contracting Officer Representative. If the Subcontractor has an established Quality Control program with designated organization element and personnel, the prime Contractor may designate an appropriate individual in that organization as his authorized representative and complete the testing and inspection report as described above. Such designation shall clearly indicate that the individual is an employee of a Subcontractor and shall be subject to the approval of the Contracting Officer Representative. The Government Inspector will witness tests and make inspections at the Subcontractor's plant in accordance with Paragraphs (c) and

(e) above.

i. Upon satisfactory completion of items of these specifications performed by any Subcontractor, the Prime Contractor will furnish the Contracting Officer Representative an exact reproduced copy of each completed testing and inspection report relative to that item in accordance with Paragraph (g) above.

E-2 DETAILED INSPECTIONS AND CONDITION REPORTS.

a. Many items in the performance work statement call for a detailed inspection and a written report to be submitted to the Contracting Officer Representative. Each particular item will specify which areas are to be inspected and by whom, whether it be the Contractor or a Subcontractor. Every report shall include, but is not limited to: (a) what was inspected, (b) condition of item inspected, (c) recommendation of repairs and/or replacement. All costs incurred for these services shall be reflected in each particular bid item.

b. Unless otherwise specified herein, the items that require inspection by the Contractor with written report to be furnished to the Contracting Officer Representative must be completed within ten (10) days after vessel enters shipyard. The Contractor shall furnish the written reports for these items within 48 hours after each inspection.

E-3 QUALITY OF ARTICLES, MATERIALS AND EQUIPMENT.

a. Where articles, materials and equipment are required to conform to standard specifications or test of Government or other authorities incorporated by reference, they will conform to the respective editions, including amendments specified.

b. Any samples and descriptive data required shall:

(1) Be submitted within the time specified in these specifications, or, if not specified, within a reasonable time before use to permit inspection and testing.

(2) Be shipped prepaid and delivered, as specified in these specifications, or as directed by the Contracting Officer.

(3) Be marked to show the name of the material, trade name of manufacturer, place of origin, name and location of the project where the material represented by the sample is to be used, and the name of the Contractor submitting the sample.

(4) Samples not subjected to destruction tests may be retained until completion of the work but thereafter will be returned to the Contractor, if he so requests in writing, at his own expense.

Failure of any sample to pass the specified requirements will be sufficient cause for refusal to consider further any samples from the same manufacturer whose materials failed to pass the tests.
