1. The Inspector will visually inspect each manhole for compliance with the specifications.

2. In accordance with OAC 252:656-5-4(g)(5) a manhole leakage test must be performed.

For manholes that are concrete and poured monolithically; and subsequent to all pipe connections in place to the manhole (normal lateral, lineal, or drop connection); and all connections having water stop gaskets cast within the manhole; and cast in place manhole barrel sections in a continuous pour without seams or joints; the contractor and City of Norman inspector shall perform a visual inspection for leaks. If leaks are observed, immediate procedures must be performed to eliminate the leaks. If no leaks are observed, the manhole shall be acceptable. In case of discrepancies, the City Engineer shall be contacted to review the manhole and the City Engineer shall make the final determination if repair or additional tests will be required.

For pre-cast manholes, a list of acceptable manhole manufacturers must be provided with each manufacturer providing written certification of satisfactory manufacturer manhole leakage testing. Any pre-cast manhole apparently damaged during the construction process must be field tested for leakage in accordance with the referenced standard, and repaired, if required by the City Engineer.

3. If a dye test is required it will be prepared in the same manner as a line test except: (a) The dye injection will be at 4 equally spaced locations around the manhole.

(b) Dye will be injected until, in the opinion of the Utility Inspector, the area is saturated. (c) The Project Inspector will observe the manhole for 30 minutes and if dye appears on the walls of the manhole, the manhole has failed the test. If the manhole fails the test, the contractor will make necessary repairs and retest.

(14)

C. Required Results:

1. The manhole must pass the visual inspection. 2. If required, the manhole must pass the vacuum test.

B. No Surety will be accepted who is now in default or delinquent on any bond or who is interested in any litigation against the City. All bonds shall be made on forms furnished by the City and shall be executed by surety companies licensed to do business in the State of Oklahoma and acceptable to the City.

(28)

1103.6

FAILURE TO EXECUTE CONTRACT

Upon failure of the Bidder to execute the required bonds or to sign the required contract within fifteen (15) days after the contract is transmitted to the Contractor, he will be considered to have abandoned his proposal. By reason of the uncertainty of market prices of the materials and labor and it being impracticable and extremely difficult to fix the amount of damages to which the City would be put by reasons of said Bidder's failure to execute said Bonds and Contract, the proposal guaranty accompanying the proposal shall be the agreed amount of damages which the City will suffer by reason of such failure on the part of the Bidder and shall thereupon be retained by the City as liquidated damages. The filing of a proposal will be considered as an acceptance of this provision.

1104.4

ALTERATIONS OF PLANS AND SPECIFICATIONS

The City reserves the right to make such changes in the plans and in the character of the work as may be necessary or desirable to insure completion of the work in the most satisfactory manner, provided such changes do not materially alter the original plans and specifications or change the general nature of the work as a whole.

The Contractor shall furnish accepted materials from other sources, if for any reason the product from any source at any time before commencing or during the prosecution of the work proves unacceptable. After acceptance, any material which has become mixed with or coated by dirt or any other foreign substance during its delivery and handling shall not be used in the work.

1105.8

APPROVAL OF MATERIALS

Before ordering materials, the Contractor shall make written request to the Engineer for review and acceptance of, the use of any materials, construction, etc., other than those mentioned as standard in the specifications or so indicated on the drawings, and obtain his acceptance of materials, construction, etc., proposed for use when "accepted" materials or work are specified without mentioning any standard by name. The terms "accepted" or "accepted equal" shall mean accepted by the Engineer.
