DESCRIPTION
608.01 Description
This work consists of constructing sanitary sewers, or parts of sewers, composed of the kinds and dimensions of pipe shown on the Plans or established by the Engineer. The work also includes such inc identals, materials, and labor as may be necessary to make connections with other structures, as shown on the Plans or as directed by the Engineer. MATERIALS

608.03 Equipment
Provide equipment as specified in 607.03. CONSTRUCTION REQUIREMENTS
608.04 Preliminary Work
Perform Clearing and Grubbing, Removal of Structures and Obstructions, Excavation and Undercutting, and Embankment Construction as specified in 201, 202, 203, and 205.
608.05 Structure Excavation and Foundation Preparation
Perform Structure Excavation and Foundation Preparation as specified for pipe culverts in 204. Provide bedding for sanitary sewers that conforms to the requirements of
204.10 B for Class A, Class B, or Class C. If no bedding class is specified,
comply with the requirements for Class C bedding.
608.06 Laying Pipe
If new facilities or other construction interfere with the existing flow of sewage, provide satisfactory by -pass facilities. Do not divert sewage into an open ditch at any time. Unless otherwise specified, the Department will not directly pay for the costs incurred in providing by -pass facilities but will consider this work to be incidental to other items of const ruction. Lay pipe without break in grade from structure to structure and with the bell or groove end upgrade. Ensure that each section has firm bearing throughout its length and forms a close concentric joint with the adjoining pipe. Make junctions and t urns with standard or special fittings. Do not allow water to run or stand in the trench while pipe laying is in progress, before the joint has completely set, or before the trench has been 608.07 589 backfilled. Do not open up more trench at any time than the available pumping facilities are able to dewa ter. If the work ceases for any reason, securely close the end of the pipe with a tight fitting plug or cover. For all branch openings or service connections provided for future use, securely close with a tight fitting plug and seal to prevent leakage. P lug open ends of pipe to be abandoned, and seal in a manner approved by the Engineer. When the pipe connects with structures, place or cut off the exposed ends to be flush with the interior face of the structure and make satisfactory connections. Take up a nd relay, at no cost to the Department, pipe that is not in good alignment, shows undue settlement, or is damaged.
608.07 Constructing Joints
Lay pipe and seal joints in a continuous operation. Seal all joints during the same day in which the sections of pipe are laid. Construct the joints to be watertight, using a method of connection that meets the Engineer’s approval. Clean the joints of cast iron pipe, and then joint and seal with materials recommended by the pip e manufacturer. Make joints in concrete or clay pipe with hemp or oakum gaskets impregnated with hot asphalt and sealed with hot poured sewer joint sealing compound, hemp or oakum gaskets impregnated with neat cement grout and sealed with mortar, rubber ga skets, mastic compound, or other elastic material, or other types of joint recommended by the pipe manufacturer. As the work progresses, clean the interior of all pipe in place.
608.08 Connections
Make connections by construc ting manholes or other structures or installing wyes or tees as shown on the Plans or directed by the Engineer. Install wyes and tees for future connections as shown or directed. Make connections to existing structures and sanitary sewer house service connections as shown on the Plans or directed by the Engineer. 608.09 590 Include the cost of temporary connections and disinfecting and deodorizing excavation or sewage in the unit price bid for other items of construction.
608.09 Test for Watertightness
When required, perform tests for watertightness at no cost to the Department. Conduct the tests in the presence of the Engineer and in accordance with the established procedures prescribed by the local municipality, utility, or ow ner. Rebuild or repair, as required and at no cost to the Department, all sanitary sewers and connections showing leakage in excess of that allowed by the local codes or established regulations. The Engineer will only accept rebuilt or repaired sewers tha t pass the above test.
608.10 Backfilling
After the pipe is installed, backfill the trench as specified in 204. COMPENSATION
608.11 Method of Measurement
The Department will measure pipe for sanitary sewers, of the various kinds, types, and sizes, by the linear foot of pipe installed and accepted. The length will be determined by measuring along the centerline of the pipe from center to center of structures, or junction fittings. An allowance of 2 feet of the kind and size of pipe in the sewer line will be made for each wye or tee required in the line. The Department will measure each kind, type, and size, determined by the nominal inside diameter of the pipe, separately. The Department will measure sanitary sewer house service connections per each. The Department will not directly pay for the labor and materials used in making branch connections and will consider this incidental to the work . Unless otherwise shown on the Plans, the Department will not measure structure excavation, and will consider such work to be incidental to other items of construction. When the Plans provide for direct payment for Structure Excavation, the Department will measure and pay for this work in accordance with 204. 608.12 591 608.12 Basis of Payment The Department will pay for accepted quantities at the contract prices as follows: Item Pay Unit __” Sanitary Sewer Pipe Linear Feet Sanitary Sewer House Service Connections Each Such payment is full compensation for all labor, materials, and incidentals necessary to complete the items. 609.01 592 SECTION 609 – PIPE REMOVED AND RELAID
