INTRODUCTION

These specifications were written to provide a comprehensive, uniform and consistent template for the procurement of sewer line cleaning and inspection services based on the current industry services and technologies. They have been created and reviewed by industry experts including Contractors, Equipment Manufacturers and their Representatives, Municipalities, Engineers, Operators, and Field Technicians. It is hoped that facility Owners will find this useful in their procurement processes and that other parties involved in this industry find it helpful in clarifying what might otherwise be ambiguous.

This document was developed to provide clarity on the issues that have proven problematic for the procurement of pipeline cleaning services. Encompassing all industry perspectives, this document strives to offer an understanding and knowledge base from which all parties can communicate in a clear and concise manner.

This document was created to allow flexibility for the end-user, whether the Owner, engineer and or municipality. As a guideline, this document is not meant to be simply cut and pasted into a specification. Flexibility rests in the ability to customize the specification to your specific budget and service requirements. The specification requires the facility Owner to make decisions while creating the document. This level of customization is necessary because specific services or technologies may not be applicable to all geographic locations or each specific project. Decisions must be made to alter and affect the outcome of the project to best suit the budget and service requirements.

Should you find this document lacking in any way, we would welcome your comments and suggestions for improvement in future revisions.

PART 1 - GENERAL

1.1 SCOPE OF SERVICES AND WORK PHASING

A. The purpose of this bid is to obtain competitive unit prices for all labor, material, and equipment necessary to clean and inspect via closed-circuit television (CCTV) existing sanitary and combined sewers ranging in size from 6- to 30-inch diameter. The work includes hydraulic root cutting and cleaning, grinding protruding break-in service connections, remote televising and recording of the sewer. All project locations will be within the Owner service area.

B. The work to be completed on each section of sewer will be performed in phases as defined in the following:

1. Phase 1 Pre-cleaning Inspection.

a. The preferred method for Pre-Cleaning Inspection is color CCTV conforming to NASSCO Pipeline Assessment Certification Program (PACP), and for the data to be exported electronically in a PACP certified format. Since this inspection is performed prior to cleaning, it is understood that the video may not provide an “unobstructed view of the entire pipe”.

b. The Contractor may propose other methods to the Owner prior to bid for inspection such as, zoom camera inspection, digital sidewall scanning inspections, acoustical technology, etc.

c. If the Contractor is performing the Pre-Cleaning Inspection, the method must be pre-approved by the Owner prior to inspection of the sewer interior.

2. Phase 2 Sewer Pipe Cleaning. Based on the Owner’s review, he or she will determine if additional work will be required. At the sole discretion of the Owner is to either declare the work on the particular sewer segment complete or notify the Contractor of additional work (i.e. Phase 3: Light Sewer Cleaning, Heavy Cleaning, Deposit Cut, Root Cut Medium, Root Cut Ball, or Lateral Cut)

3. Phase 3 Additional Sewer Pipe Cleaning (Optional). The Contractor shall perform the assigned additional work, which may be any one of the following items as defined in these specifications: Light Sewer Cleaning, Heavy Cleaning, Deposit Cut, Root Cut Medium, Root Cut Ball, or Lateral Cut

4. Phase 4 Post Cleaning Inspection. Final televising of the sewer segment to evaluate the condition of the sewer segment after all cleaning has been performed in Phase 3. Phase 4 will be required to be performed and will be reimbursed at the bid unit price.

a. The recorded video must show the entire circumference of the sewer. Any flow control to remove standing water and debris shall be incidental to the contract. It is not the intent of this specification to require bypass pumping to control heavy flow; however, the Contractor must, at a minimum, make reasonable effort to control the flow by using flushing equipment to temporarily retain flow or to remove standing water. The Contractor must also consider weather conditions to obtain the best video image of the sewer. This may require the Contractor to delay any video work after major rain events until the system can return to lower dry weather flow. The Contractor shall submit PACP data to include the electronic video reports, logs, etc. for the Owner’s review as required in Part 1 Section 6.

b. The segments of sewer to be cleaned and televised through this contract will be located primarily within the paved areas of the public right-of-way;

however, there may be some sewer segments that are located within public easements on private property. The successful bidder, with assistance of the Owner as required, will be responsible to coordinate and gain access to any and all sewer segments and will be responsible for any restoration in accordance with Part III Section 5. This will include written authorization between Contractor and landowner.

C. The Contractor shall furnish all labor, components, materials, tools, and appurtenances necessary for the performance and completion of the contract.

D. Award of the contract will be determined through an evaluation of bids and made in light of the best interest of the Owner.

E. The Contractor will be held fully liable for any damages incurred that are caused by his or her negligence.

F. Patents, Trade Secrets, and Copyrights: The Contractor shall pay all license fees and royalties and assume all costs incidental to the use in the performance of the work or the incorporation in the work of any invention, design, process, product or device which is the subject of patent rights, trade secrets protection rights, or copyrights held by others. The Contractor shall indemnify and hold harmless the Owner and Engineer and anyone directly or indirectly employed by either of them from and against all claims, damages, losses and expenses (including attorney’s fees and court and arbitration costs) arising out of any infringement of patent rights, trade secret protection rights, or copyrights incidental to the use in the performance of the work or resulting from the incorporation in the work of any invention, design, process, product or device not specified in the contract documents, and shall defend all such claims in connection with any alleged infringement of such rights.

1.2 OWNER

A. This contract will be administered and performed under the direction and inspection of the Owner. Questions pertaining to this contract, before and after award, should be directed to the Owner at (PHONE NUMBER) and (EMAIL ADDRESS).

1.3 TIME OF PERFORMANCE, SCHEDULING AND LIQUIDATED DAMAGES

A. Upon award of the contract, the Contractor shall CCTV at least three (3) segments or 1,000 feet of pipe and submit the data to the Owner to verify that the CCTV database is compatible with the Owner’s PACP Database, and the deliverables are acceptable to the Owner. The Owner shall verify acceptability of the deliverables within five (5) business days of receipt. After the Owner verifies compatibility of the database, the Owner shall then issue to the Contractor a written “Notice to Proceed” including a date for commencement of work. The Contractor shall begin work on the date stated in the written “Notice To Proceed” (but no later than 10 calendar days after receipt) with an adequate force and sufficient resources to demonstrate due diligence in the performance of the contract.
