1.2 UNIT PRICE PAY ITEMS

A. The estimated number of bid units, as listed in the Price Schedule on the Bid Form, are approximate only and are included solely for the purpose of comparison of Bids. The OWNER does not expressly or by implication agree that the estimated number of units will correspond with the number of units actually needed and reserves the right to increase or decrease any quantity or to eliminate any quantity as the OWNER may deem necessary. Except as provided in Paragraph 1.3, CONTRACTOR or the OWNER will not be entitled to any adjustment in a unit bid price as a result of any change in an estimated quantity and agrees to accept the aforesaid unit bid prices as complete and total compensation for any additions caused by changes or alterations in the Work ordered by the OWNER.

B. Force Account and Additional Bid Items - Extra Work:


1. General - Work not covered by Contract Items necessary for the completion of the contract, or proposed emergency construction may be considered as extra work and will be paid for under terms of Additional Bid Items, force account, or by change order procedure given in Section 01035 – Change Order and Work Order Procedures for items not listed in the Additional Bid Items.

2. The amount to be paid to the CONTRACTOR for work done under force account shall be the sum of the component costs of such work, directly chargeable thereto, as defined hereunder in the numbered paragraphs 1.2, B.3.a. to B.3.f., inclusive.

3. The amount paid to the CONTRACTOR as provided in the preceding paragraphs shall be understood to include full compensation for any and all expenses incurred by the CONTRACTOR and his Subcontractors in connection with the force account work. The aforementioned component costs shall be as follows:

a. The cost of labor, including foremen, for the time actually engaged on site on the force account work. CONTRACTOR’s workers will be compensated at the rate of their duty performed (i.e.- A foreman working as an operator would be compensated by the OWNER as an operator.)

b. The cost of materials furnished, other than those, if any, furnished by the OWNER, incorporated into, or necessarily used in the prosecution of, the force account work, less the salvage value of any materials salvaged upon completion of such work.

1.3 ADJUSTMENT OF UNIT PRICES FOR INCREASE OR DECREASE OF ESTIMATED QUANTITIES

A. For bid items paid for on a unit price basis, increases or decreases in the quantity of an item of Work will be determined by comparing the total payable quantity of Work with the unit price pay items as shown in the Price Schedule.

B. If the total payable quantity of any unit price item of Work varies from the unit price pay items by more than 25 percent, the unit price of that item will be a subject of review by the OWNER. Only those items which have an as-bid computed total value of 5 percent or more of the sum of the as-bid computed total values of all items bid are subject to review by the OWNER.

A. The specifications call attention to certain features but do not purport to cover all details entering into the required work

B. General: Perform CCTV inspection on one sewer section (i.e. manhole to manhole) at a time.

C. Survey CCTV Inspection: Perform survey CCTV inspection immediately after pipeline cleaning, unless specifically allowed by the OWNER. Do not allow inspection camera to immediately follow behind the cleaning mechanism, but rather follow once at a minimum distance of 8-feet from nozzle. Verify the


pipeline is clean, verify or measure the pipe sizes, determine existing condition of the pipeline and locate service connections.

D. Flow Control: Adequately control the flow in the pipeline being CCTV inspected. Do not exceed the depth of wastewater flow shown below:

Pipe Diameter(Inches)

Depth of Flow(Percent of Pipe Diameter)

6 – 10 10

12 – 24 15

Over 24 20

1. If during CCTV inspection of a sewer section, the wastewater flow depth exceeds the maximum allowable, reduce the flow depth to an acceptable level by performing the survey CCTV inspection during minimum flow hours, by diversion pumping or by pulling a camera with swab, high-velocity jet nozzle or other acceptable dewatering device. If pulling with a jet nozzle, the camera must be a minimum of 8-feet from the nozzle. Divert the flow in accordance with Section 02150 – Bypass Pumping.

2. No flow is allowed in the pipeline while performing post-installation CCTV inspection. Divert the flow in accordance with Section 02150 – Bypass Pumping.

E. Pipeline Inspection Camera: Move the pipe inspection camera through the pipeline in the downstream direction at a uniform rate, stopping when necessary to ensure proper documentation of the sewer's condition and service connections, but do not pull the pipe inspection camera at a speed greater than 30 feet per minute or 9 meters per minute. Position camera for inspection at the center point of the diameter or as nearest the center of non-circular piping.

F. Pipeline Conditions: Inspect pipelines by use of the pan-and-tilt feature of the pipe

inspection to determine the condition of the pipeline. Document the conditions, defects and observations of pipelines using NASSCO’s Pipeline Assessment and Certification Program© codes.

G. Locating Point Repairs Necessary to Complete Inspection: If point repair is needed in order for the continuous inspection to be completed from manhole to manhole due to impassibility or sewer collapse, make a special note in the documentation and inspection report as outlined in Section 3.3 below.

H. Inspection of Service Connections during Mainline Inspection: Inspect service connections by use of the pan-and-tilt feature of the pipe inspection camera. Include the connection to the sewer main and lamping inspection up the service pipe, recording all defects found in the service connection as the focus of the
