Rivers Project Office – Service Base Water Line Life Cycle Replacement March 2019

Scope of Work

1.0 DESCRIPTION OF WORK

The work consists of furnishing all labor, materials, fittings, equipment, tools, power, heat, water, etc., and performing all work to replace an existing fleet potable water system. The demo and proper disposal of the replaced systems is the contractor’s responsibility. Replaced systems will not be abandoned in place. Included below is all work to be completed.

Deliveries and work must be coordinated with the Contracting Officer or other designated Government Authority, such as the Contracting Officer Representative (COR) one week in advance. Contractor representative must be on sight during all deliveries. Contractor is to coordinate with COR on material storage locations. All materials and equipment furnished shall be new, unused, and free from defects or imperfections that might affect the serviceability of the finished product.

Work and components must meet all government and Metropolitan St. Louis Sewer District standards.

Contractor is to use off the shelf components when able. Potable water system will be resistant to Mississippi river conditions. All items provided must meet the requirements of the Buy American clauses referenced. The contractor is responsible for field verifying all measurements.

1.1 Water Line

Demolish and properly dispose of existing potable water system that is to be replaced. Furnish new potable water system meeting the following requirements. Potable water lines will be stainless steel and flexible lines designed for potable water use. Potable water system will not interfere with the removal of the trestle hand rails. Potable water system will not interfere with the trestle to string out access ramp. Contractor will be responsible for integrating replacement fleet potable water system with existing galvanized system at the 3” to 2” reducer located south of the trestle. Contractor will install a locking ball valve on the vessel string out to separate new stainless steel system from existing galvanized system. Contractor is to match existing vessel connections types and locations (Attachment 1). Contractor will be replacing approximately 950 ft. of pipe. Potable water system must be easily drainable utilizing gravity. Potable water system will be resistant to impacts from debris floating on the Mississippi River.

1.2 Heat Trace

The potable water lines including but not limited to connection points, pipes, couplings, and fittings will be heat traced and insulated. System will be designed to prevent pipes from freezing if exposed to Mississippi river conditions at -20 degrees Fahrenheit. Contractor will be responsible for powering the heat trace, 110V AC and 480V AC power is located on the string out.

1.3 Insulation

The insulation will be closed cell foam, when exposed to the elements it will not absorb water.

Insulation will have a minimum service temperature range of -40oF to 250oF. Insulation Tensile Strength will exceed 4,000 PSI with a minimum Shore D Hardness of 57. Insulations average thermal resistance

(R) shale be 12.53 (hr*ft2*oF)/Btu or greater. An example of such insulation would be dragon jacket.

1.4 Close Out

The contractor shall submit to the government a “close out packet” that contains contractor workmanship warranty, final design specs, material lists, material manufacture warranties, and suggested operation and maintenance.

2.1 EPA Designated (CPG): Under the Comprehensive Procurement Guidelines (CPG) program, the

Environmental Protection Agency (EPA) designates products that are or can be made with recovered materials, and recommends practices for buying these products. Any designated product that is being offered or supplied under this contract shall meet the minimum recommended content levels as identified under the CPG program. Visit http://www.epa.gov/epawaste/conserve/tools/cpg/products for a complete list of designated products and the associated recommended content levels. Offerors must be able to demonstrate that each offered product meets minimum content levels upon request.

Option1

Vault Demolish and properly dispose of existing vault system. Furnish and install new vault system meeting the following requirements. Vault will contain new functional displacement-type odometer style water meter, back flow preventer, and redundant shut of valves with a minimum pipe 3” diameter. The vault will be large enough for a worker to preform inspections and replacements in comfortably with a minimum 2 ft. working space. Vault must contain a system to prevent it from retaining water under normal conditions. Existing vault is located on a levee. All excavations must be at least 15’ away from the river wall. All excavated areas excluding the inside of the vault and pipes must be backfilled using flowable fill per I Dot specifications. Shoring will be provided by through the use of H-Pile or sheet piling on the east side of the vault nearest the river.

Water meter accuracy shall be such that at a water temperature less than 80ºF (27ºC):

1. Normal flow limits. At any rate of flow within the normal test-flow limits of meter design, the meter shall register not less than 98.5 percent and not more than 101.5 percent of the water that actually passes through it.

2. Minimum flow rate. At the minimum test-flow rate to the lowest normal test-flow rate of meter design, the meter shall register not less than 95 percent and not more than 101 percent of the water that actually passes through it.

Inspection All materials and workmanship shall be subject to inspection at all times by an inspector or inspectors appointed by the contracting Officer to ensure strict compliance with the terms of the contract in accordance with Contract The presence or absence of the inspector shall not relieve the Contractor or his responsible agent of the responsibility for the proper execution of the contract. The Contractor shall at all times permit the Government inspector(s) free access to the shops where work is being carried on under the contract, and shall provide the necessary facilities and assistance for making thorough examinations. Government inspectors shall have power to reject any workmanship and material which do not conform to the specifications. Inspections shall be made within 10 calendar days after system complete installation.

Acceptance When final inspection of potable water system has been satisfactorily completed it will be formally approved by the Contracting Officer or his /her representative for their behalf of the Government.

Conditions of Operations The Potable water system supplies drinking water to our vessels throughout the year at different locations along the string out. Vessels connect to the potable water line by removable hoses. Sections of the potable water line may be submerged in the Mississippi river at different times throughout the year. Water usage by the Vessels is monitored by Metropolitan St. Louis Sewer District and the service base
