General Specifications

1. Explanation

The Specifications are divided into General Specifications and Detail Specifications. The General

Specifications pertain to the relations between the Contractor and the State. The Detail

Specifications describe each class of construction work, define and classify materials involved in the work, and explain the manner in which each class of work shall be done and how it will be measured.

2. Definitions

Whenever the words herein defined or pronouns used in their stead occur in the Contract and

Specifications, they shall have the meaning here given.

The word "State" shall mean Department of General Services as related to bid and award and the

West Tennessee River Basin Authority as related to work performance and payment.

The word "Engineer" shall mean West Tennessee River Basin Authority or its authorized representative.

The word "Contractor" shall mean the person, partnership, or corporation entering into this

Contract for the performance of work, or the agent appointed to act for the Contractor in the performance of the work.

Whenever figures are given in the Specifications following the word "Elevation", or where figures representing elevations are given, they shall mean distance in feet above the U.S. Geological

Survey Sea Level Datum or a locally established job site datum, if so noted on the plans.

3. Examinations and Investigations

The offering of a bid by the Contractor for the work under this Contract shall constitute a good and sufficient declaration on the part of the Contractor that he has examined, to his complete satisfaction, the nature of the work, and the various means of approach to the work, and has made all necessary investigations in order to inform himself thoroughly as to the character and magnitude of all work involved in the complete execution of the Contract, and also of the facilities

ITB # 32701-13862 Specifications 7 for delivering and handling materials, and that he has familiarized himself with all local conditions and other circumstances that may be encountered in the performance of the work. The offering of the bid shall be a waiver on the part of the Contractor of all claims for extra compensation as a result of his failure to make such examinations and investigations.

4. Equipment

The Contractor shall employ equipment of such size and character that a rate of progress can be maintained that will ensure the completion of the work within the time specified in the Contract and that will ensure a satisfactory quality of work. The approval of the Engineer of the

Contractor’s equipment shall not relieve the Contractor of his obligation to maintain the required rate of progress, in the event the equipment proves to be inadequate.

The Contractor shall not sell or remove equipment or materials that have been installed and that may be necessary for the completion of the work without the written consent of the Engineer.

5. Direction of Work

Prior to the start of construction, the Contractor shall call a pre-construction conference, including his Project Superintendent and his Foreman, the Engineer, and others as the Engineer may direct.

The purpose of this meeting is to review the requirements of the Contract, Permit and Construction

Documents to assure complete understanding of the specific responsibilities of each participant and his relationship with the others involved.

The Engineer shall have the right to direct the manner in which all work is to be conducted insofar as may be necessary to secure the proper progress and quality of the work, and all directions and instructions of the Engineer, or any of his inspectors or other agents shall be carried out by the

Contractor. In order to ensure the proper completion of the Contract, the Engineer may, if necessary, determine the order of precedence in which any part of the work shall be commenced and carried on.

The Contractor agrees that notwithstanding the general supervisory control that may be exercised by the Engineer and State over the work to be done under the terms of this Contract and the specifications, that his responsibilities and liabilities are those of an independent contractor.

6. Inspection of Work

ITB # 32701-13862 Specifications 8

All work and material furnished shall be subject at all times to a thorough and minute inspection by the Engineer. The Contractor shall permit access at all times to every part of the work and to all points where materials to be used in the work are manufactured, procured or stored.

7. Lines and Grades

See the attachment labeled Floodplain Bench Construction Drawings.

8. Determination of Quantities and Measurements

The Engineer shall determine all quantities and amounts of work performed.

9. Changes and Alterations

The State reserves the right to make any alterations, eliminations or additions that it may deem necessary in the work to be done, or any part thereof, and to make any variations on the quantity of work to be done, provided that any such alterations, eliminations, and additions shall not materially alter the general character of work as a whole.

If such changes diminish the quantity of work to be done, they shall not constitute a claim for damages for loss of anticipated profits on the work already done or material already furnished or used in the work. The State shall make payment to the Contractor for such work or materials at the unit price stipulated in the Contract. If by reason of changes the amount of work is increased, such increase shall be paid for according to the quantities actually done, and at the unit price established for such work under the contract.

10. Defective Work and Materials

If the work should be damaged in any way, or if any defects not readily detected by inspection develop before the final acceptance of the whole work, unless hereinafter otherwise specified, the

Contractor shall correct such damage or defect without additional compensation. If the Contractor shall fail to reconstruct any defective or damaged work after reasonable notice, the Engineer may cause such work to be reconstructed, and the expense thereof shall be deducted from the amount to be paid to the Contractor.

If upon any work that is defective or damaged, the imperfection, in the opinion of the Engineer, is not sufficiently important to require reconstruction, the State shall have the right to make such deductions as the Engineer may determine to be just and reasonable, from the amounts due or to become due the Contractor instead of requiring the imperfect part to be reconstructed.

ITB # 32701-13862 Specifications 9

11. Time and Order of Completion

Determination as to whether the required rate of progress is being maintained may be made at any time after the work has started, by comparing the value at the contract price of the amount of work done, with the value at the Contract price of the amount of work necessary to have been accomplished during such period in order to have maintained the prescribed rate of progress. In determining progress; the work shall be assumed to have begun at the date of the Purchase Order, and proper consideration shall be given to any extensions of time that may have been granted. Any failure to maintain the required rate of progress, after taking into consideration extensions of time that have been granted, shall be a breach of contract, just as would be a failure to complete the entire work within the specified time.

Completion time and actual contract term may not coincide. Contract Term is for fiscal and payment purposes only and does not alter stated time for completion.

Contract Term may be extended for final inspection and fiscal reasons without comment, but extension of contract term to alter completion times must be requested in writing to the West

Tennessee River Basin Authority and a copy of this request signed by the director and forwarded to the state Contract administrator.

Assessment of damages shall be the sole responsibility of the engineer and the Director of the

Authority.

12. Extension of Time

Delays due to causes beyond the control of the Contractor, other than those that, in the opinion of the Engineer, reasonably would be expected to occur in connection with the performance of the work, may entitle the Contractor, to an extension of time for completing the work sufficient to compensate for such delay. No extension of time shall be granted, however, unless the Contractor shall, within fifteen (15) days from the beginning of the delay, notify the Engineer in writing of such delay, and of the time of beginning and the cause of the same. After work is resumed, the

Engineer will determine the extension of time, if any, that shall be allowed the Contractor, and his decision shall be binding and conclusive on both parties.

13. Hindrances and Delays

ITB # 32701-13862 Specifications 10

The Contractor shall bear all loss or damage for hindrances or delays, from any cause, during the progress of any part of the work under the Contract and also all loss or damage arising out of the nature of the work to be done, or from the action of the elements, or from any unforeseen conditions encountered in connection with the work, or from any other cause whatever. No charge other than that included in the Contract price for the work shall be made by the

Contractor against the State for such loss or damage.

14. Payment Determinations

During the progress of the work, and about once a month, the Engineer will make an estimate of the amount and value of the work done and materials incorporated into the work by the Contractor.

The Engineer may, at his discretion, defer a current estimate until the value of the work done and materials incorporated into the work since the preceding estimate is in excess of $500.

As soon as practicable after a current estimate is made by the Engineer, the State shall pay the

Contractor 100 percent of the value, at the unit price or prices stipulated in the Contract, of the work done and the materials incorporated into the work since the preceding estimate.

15. Final Payment

As soon as practicable after the work covered by the Contract has been completed in a manner satisfactory to the Engineer and the State, the Engineer will prepare a final determination showing the total amount of work done under the Contract and value thereof and the amount due the

Contractor under such final determination. Final payment will be made at that time by the State.

All prior estimates and payments shall be superseded by and shall be subject to correction in the final determination. Final payment will be held by the State until the Contractor furnishes the State with an affidavit as to payment of labor and material bills furnished and used on this Contract, and acceptance and approval of payment has been received by the State from the bonding company or surety. Thereupon the State shall release the Contractor’s bond and any contractual responsibilities attached thereto. Final acceptance of the work, and release of the Contractor’s bond, shall also be a release to the State from all claims against the State on account of this Contract.
