SECTION I. INTRODUCTION

BACKGROUND INFORMATION:

The Northeast Ohio Regional Sewer District (District) is a political subdivision of the State of Ohio and organized under Chapter 6119 of the Ohio Revised Code. Originally named Cleveland Regional Sewer District, it was created in 1972 to assume the Ownership, Operation and Maintenance of wastewater collection, treatment and disposal facilities servicing the member communities in the Cleveland metropolitan area.

The District’s sewer system consists primarily of large diameter pipes, many constructed of bricks, many egg-shaped pipes, and some over 100 years old. The District is responsible for 126 combined sewer outfalls and 358 flow regulator structures. The District owns and operates three treatment facilities: Easterly, Southerly and Westerly.

SEWER SYSTEM INSPECTION AND REHABILITATION PROGRAM:

In 1994, the District completed a system-wide Combined Sewer Overflow Facilities Plan Phase I Study. The Phase I study recommended that more detailed Combined Sewer Overflow Plans be developed that included the evaluation of the capability, capacity, and the condition of the District’s existing sewer system. Subsequent to that study the NEORSD embarked on detailed facility planning efforts in each of their three WWTP service areas. Concurrent with the facilities plans the inspection and evaluation program was initiated.

In 1995, the Northeast Ohio Regional Sewer District began a comprehensive inspection and evaluation of the interceptor and combined overflow system. The Inspection and Evaluation program consisted of the internal inspection of over 1.1 million feet of sewer and over 5,200 manholes. Both interceptor sewers and combined sewer overflow pipes were inspected as part of the program. The NEORSD sewer system consists mainly of sewers larger than 36-inch diameter sewers (85% greater than 36-inch), many of which are constructed of brick or clay tile (70% of total) and many that are egg-shaped (35% of total).

An inspection and condition assessment of the Southerly Broadway Branch Interceptor was performed in 2001. Portions of the sewers were not inspected due to extensive debris especially near the intersection of Broadway Avenue and Aetna Road.

In March 2004, repeated reports of basement flooding in the Broadway and Aetna area led to an investigation of the District’s No. 6 Brick Sewer, the Broadway Interceptor. The investigation identified a crown collapse with adjacent reaches of distressed pipe. Emergency action was requested. The work, as initially viewed, included the replacement of approximately 100 lf of No. 6 Brick with new 48” RCP and new manhole construction. After excavation of the failed section and additional cleaning and video inspection, two more collapsed areas were identified extending north to the buried junction of the Broadway Interceptor and the existing 24” sewer from Aetna Road. Consequently, the scope of the emergency repair was expanded to include an additional 150 lf of sewer replacement, construction of a new junction manhole at Broadway and Aetna and a transition chamber between the newly installed 48” RCP and Existing No. 6 Brick Sewer. Please see Exhibit A for a map and description of the repairs.

In April 2007, the District hired an emergency contractor to perform emergency sewer repairs between Manholes SOCLB00000100INM and SOCLB00000040INM that were discovered on a cleaning contract. Multiple sewer defects including holes and missing bricks were discovered within the sewer. Extensive external voids were encountered and, in some cases, the sub-base of the road could be observed. It was recommended that the District reline these stretches (approximately 3,500 LF) of sewer with a final more permanent lining system (cured-in-place pipe). The soil conditions surrounding this sewer consist of loose sand. This loose sand is thought to migrate inside of the sewer through gaps in the mortar and laterals causing the sidewalls of the sewer to lose their support. This loss of support causes the sewer to move outward introducing cracks and fractures which eventually lead to total collapse. Please see Exhibit B for a map and description of the repairs.

In October 2007, the District hired a contractor to perform sewer repair work (approximately 2,700 LF) between Manholes SOCLB00000180INM and SOCLB00000130INM. These sections of sewer (42” in diameter) were relined using a cured-in-place pipe. Please see Exhibit C for detailed drawings of the repair work. This work was a result of sewer rehabilitation recommendations based on a sewer inspection project performed in 1998.

SECTION II: GENERAL SCOPE OF SERVICES

The scope of work for the CSO Rehabilitation Contract for design and professional services shall consist of, but not be limited to, the tasks as outlined below. The design contracts will be advertised for construction bids as per Ohio Revised Code (ORC) requirements. The District will not entertain design build contracts for the completion of this work.

The tasks as described on the following pages are the preferred means and methods of the District. The Consultant should base their proposal on the described tasks. The analysis shall contain information pertaining to costs, operations, maintenance, constructability, environmental impacts, etc.

CONSULTANTS RESPONSIBILITIES:

The selected consultant shall provide all engineering services necessary to develop and produce complete detailed design packages that will culminate in up to three (3) bid packages, cleaning, minor repairs, and relining/replacement or a combination thereof. The consultant shall work with the District personnel to achieve the District’s desired scope of work. The Consultant shall carefully consider the input by the District’s staff but based on the Consultant’s own experience and ability, shall be solely responsible to provide a complete and workable design package in accordance with the requirements of the scope of work.

GENERAL:

Provide a comprehensive design package consisting of plans and specifications bidding of the identified pipes and manholes to be rehabilitated. The District’s minimum requirements are:

  1. Become familiar with the sewer infrastructure by visiting the identified locations of sewer defects. Gather drawings and specifications in the District’s possession. All requests for information must be submitted to the District’s Engineering and Construction Department.
  2. Become familiar with the surroundings and how a Contractor may stage the work. Pay particular attention to traffic congestion and utilities (including overhead).
  3. The Consultant shall examine criticality aspects of the work prioritize projects and suggest a sequence of construction. The initial thought is to have bid packages ready for a service agreement/cleaning contract twelve (12) months after the Notice To Proceed (NTP) and a relining and replacement contract ready after sixteen (16) months from the NTP. After review of the information, the designer may recommend a separate cleaning contract.

Upon completion of the Inspection and Evaluation Program the District focused rehabilitation efforts on the interceptor system. Over the past 5 years nearly $43M in rehabilitation has been performed on the interceptor system. The projects included Service Agreement Contracts (point repairs), Hydraulic Improvement Contracts (cleaning), Relining and Replacement Contracts, and a Manhole Rehabilitation Contract.

As a result of the sewers inherited from the April 2005 agreement with the City of Cleveland (approximately 80,000 LF of sewer and 533 manholes), sewer rehabilitation efforts have shifted to the combined sewer overflow (CSO) network. The CSO sewer network consists of approximately 50 miles of sewer. Pipe sizes range from 6 inches to 192 inches. Rehabilitation recommendations made during the Inspection and Evaluation Project are as follows:

Approximately 47,000 LF of sewers and 121 manholes were recommended for spot repair

Approximately 49,000 LF of sewers were recommended for cleaning

Approximately 13,300 LF of sewers and 3 manholes were recommended for relining/replacement.

The CSORC consists of analyzing existing sewer inspection data, obtaining additional information necessary for design, and design services to compile bid documents for a service agreement contract, a sewer cleaning project, and a relining/replacement project. The existing inspections were performed between 1995-2001. An overall map of the alignment for the Easterly, Westerly, and Southerly Service Areas and their respective Combined Sewer Overflow (CSO) Pipe Networks are provided in Appendix A on the DVD. Please note the highlighted sewers scheduled for rehabilitation. A listing of the pipe reaches to be rehabilitated is located in Appendix A.
