The City of McKinney, Texas (“City”) is seeking bids from qualified vendors (“Contractor”) for Storm Drain Cleaning and Inspection Services as described herein. This contract, once awarded, shall be performed on as needed basis, with annual expenditures potentially up to $250,000.

II. SCOPE OF WORK

A. GENERAL - The intent of storm sewer line cleaning is to remove all foreign materials from the lines prior to televising the pipe in order to provide a clear, unobstructed view of the entire pipe. The success of the inspection phases will depend on the cleanliness of the lines. The importance of this phase of the operation cannot be over emphasized.

It is recognized that there are some conditions such as major blockages that prevent typical cleaning from being accomplished. The Contractor shall be required to remove all blockages. If in the course of normal cleaning operations, damage results to the pipe or structure of new installations, the Contractor shall be required to repair the damage or replace the pipe or structure. The Contractor shall include 24/7 availability.

The work covered by these specifications consists of furnishing all supervision, labor, materials, and equipment necessary to perform detailed Storm Draining Cleaning & Inspection services and Closed Circuit Television (CCTV) of Storm Sewer, as well as complete and submit all related data and reports; including Traffic Control by the extent required; all in accordance with these specifications and all applicable local, state and federal rules, laws, regulations and ordinances pertaining to the work

B. CONTRACT REQUIREMENTS

Cleaning Equipment - The Contractor shall supply High-Velocity Jet (Hydro cleaning) Equipment: All high-velocity sewer cleaning equipment shall be constructed for ease and safety of operation. The equipment shall have a selection of high-velocity nozzles.

The nozzles shall be capable of producing a scouring action from 15 to 45 degrees, in all size lines designated to be cleaned. Equipment shall also include a high-velocity gun for washing and scouring structure walls and floor. The gun shall be capable of producing flows from a fine spray to a solid stream. The equipment shall carry its own water tank, auxiliary engines, pumps, and hydraulically driven hose reel.

Cleaning Precautions - The Contractors shall take every precaution to avoid damage during pipe cleaning operations. Contractors working on City of McKinney projects shall obtain approval from the City before certain higher risk cleaning operations begin.

Satisfactory precautions shall be taken in the use of cleaning equipment. When hydraulically propelled cleaning tools (which depend upon water pressure to provide their cleaning force) or tools which retard the flow in the pipeline are used, precautions shall be taken to ensure that the water head pressure does not damage or cause flooding of public or private property being served by the storm sewer. Various cutter tips may need to be used depending upon site specific conditions. No fire hydrant shall be used without permission from the Utility Owner. If permission is given, the hydrant shall not be obstructed in case of a fire in the area served by the hydrant. Gate valves, backflow preventers, or an air gap shall be incorporated in the direct connection to a

BID No. 25-46ITB potable water source as required by the utility owner. A hydrant meter will be provided to the contractor each work day and must be returned at the each day.

A hydrant meter will be provided to the contractor each workday and must be returned at the end of each day.

Storm Sewer Cleaning -The designated storm sewer sections shall be cleaned using high-velocity jet, or mechanically powered equipment. Selection of the equipment used shall be based on the conditions of lines at the time the work commences. The equipment shall be capable of removing dirt, grease, rocks, sand, branches, leaves and other materials and obstructions from the storm sewer lines and structures. If cleaning an entire section cannot be successfully performed from one structure, the equipment shall be set up on the next structure and cleaning again attempted. If, again, successful cleaning cannot be performed or the equipment fails to traverse the entire section, it will be assumed that a major blockage exists and it is the Contractor’s responsibility to remove this blockage. The Contractor shall use caution during cleaning operations so as not to cause damage to the pipe section being cleaned. If subsequent televising of the pipe reveals damage caused by the cleaning operation, the damage shall be repaired by Contractor, to the City’s satisfaction, at no additional cost to the city.
