B. Construction Items:

1. Mobilization: This work is the assembly and set-up of the general plant required to comply with the contract and with local and State laws and regulations. General plant includes Contractor's offices, shops, plants, storage areas, and sanitary or other facilities. This work includes obtaining the required permits, insurance, bonds, and any other initial items required for the start of the work.

This work is incidental to the project.

2. Installation of a High Density Polyethylene Pipe Culvert Liner: This work is for slip lining existing 18 to 24 inch corrugated metal pipe and grouting of annular space between the existing pipe and liner pipe. The work, including but not limited to the following, are incidental to the pipe Linear

Foot item: Determine the necessary diameter and liner thickness based upon depth, diameter, shape, traffic loading, groundwater pressures and condition for this pipe segment; Contractor shall conduct a site visit prior to bidding on the project to determine pipe lengths to be used in the lining process.

Individual liner section lengths shall be a minimum of 6 feet but shall not exceed 20’ unless pre-approved. This Linear Feet price shall be for cleaning existing pipe; for furnishing, hauling, installing liner pipe and placing grout; fusing connections as necessary, for all labor, tools equipment, materials, clean-up and incidentals.

Submit detailed shop drawings showing all dimensions of liner pipe, material list, bracing details, bulkhead details, grout port locations, grout flow control details, and complete construction sequencing to the Department Representative. Ensure calculations are prepared and stamped by a professional engineer or manufacturers specifications.

Construction schedule shall be submitted 3 weeks prior to starting work to allow time to coordinate with property owners. The Department will coordinate with affected property owners.

Prepare the existing pipe for the installation of the liner pipe by removing all sediment and objects or parts of the existing pipe that could damage the liner pipe during installation. PennDOT’s Project Manager complete a final inspection and will notify the offeror if an internal inspection reveals an obstruction that cannot be removed by conventional cleaning equipment; and provide written guidance on how the obstruction will be resolved.

Install the liner pipe in accordance with approved shop drawings or manufacturers specifications.

Maintain consistent spacing around the liner pipe using spacers or other acceptable devices. Ensure that the annular space between the existing pipe and the liner pipe is completely filled with grout.

Patch holes and fill voids in and around existing pipe with material as required by PennDOT’s Project Manager.

3. Access, site preparation and restoration: This work is constructing access as necessary to the pipe sections, constructing work area for pipe placement and site restoration.

Replace existing pavement, curb and sidewalk, as needed, replacement should match existing material in thickness and type and sealed along joints. Refer to Sidewalk and Curb standard

RC64M and RC67M and use AAA concrete. For existing pavement replacement, refer to the flexible pavement restoration detail below.

4. Maintenance and Protection of Traffic —This work is the furnishing, installing, maintaining, and relocating of traffic control devices according to Publication 212, Publication 213, and the

MUTCD. This work may include message boards as necessary, flagging and pilot car operation for guidance of traffic through the temporary traffic control zone and dust control. Traffic will need to be restored to 2 lanes at the end of each work day and weekends.

C. Construction Meeting. The Offeror shall send a representative to attend a construction meeting after the purchase order is issued. The time and location will be provided by PennDOT’s Project Manager. The

Offeror shall be prepared to discuss access, site preparation, proposed BMP’s, Traffic Control and construction sequence at the meeting.

D. Flow Control. The selected Offeror shall, perform work with no flow or rainfall in the foreseeable future during work or curing processes.

E. Flowable Backfill, Type D. or Low-Density Cellular Concrete (LDCC)

1. Work Included: This work shall consist of batching, mixing, and placing LDCC of the appropriate density as indicated by the specifications or as directed by the engineer. A trained LDCC installer shall furnish labor, material, equipment, and supervision for the installation of the LDCC in accordance with the drawings and specifications.

2. Use skilled labor that is thoroughly trained, experienced, and familiar with the specified requirements and the methods for proper performance of this work.

3. Foam Liquid Concentrate: Shall comply with the standard specifications of ASTM C 869 when tested in accordance with ASTM C 796.

4. Cement: The Portland cement shall comply with ASTM C 150. Other supplemental cementitious material such as fly ash may be used when approved by the project engineer. Supplementary cementitious materials should be tested prior to the start of the project for compatibility with the foaming agent.

5. Admixtures: Admixtures for accelerating, water reducing, and other specific properties may be used when specifically approved by the project engineer. Admixtures should be tested prior to the start of the project for compatibility with the foaming agent.

6. Water: Use water that is potable and free from deleterious amounts of alkali, acid, and organic materials, which would adversely affect the setting or strength of the LDCC.
