SPECIFICATIONS
Furnish Replacement Final Clarifier Drive Unit
Wright Smith Jr., Wastewater Treatment Plant
1. GENERAL
1.1 Purpose
The purpose of this solicitation is to obtain competitive bids for the engineering, manufacture, furnishing, and
delivery of one (1) complete replacement drive unit for the #1 Final Clarifier at the Wright Smith Wastewater
Treatment Plant.
Bidders are highly encouraged to schedule a site visit prior to submitting a bid. Failure to obtain
information from the site or manufacturer does not grant exceptions, deviations, substitutions, or
qualifications from full compliance with the bid specifications.
1.2 Existing Equipment Reference
The replacement drive is intended for one (1) existing 126-foot-diameter C3 final clarifier. The existing equipment
reference/serial information is 23516-05 A/B. The basis-of-design replacement is an Ovivo C40DH drive unit. The
equipment and serial references are provided to assist bidders in identifying the existing configuration and required
fit and function and do not limit competition to the original equipment manufacturer.
1.3 Scope of Supply
The successful bidder shall furnish a complete replacement drive system consisting of, at minimum:
* One (1) complete clarifier drive unit assembly, Ovivo C40DH or approved equal.
* Hydraulic power unit with 1 HP motor, 460 V, three-phase electrical service.
* Digital torque monitoring control panel.
* Factory-applied protective coating system meeting Section 3.5.
* Installation fasteners and shim kit, Type 304 stainless steel.
* Operation and maintenance manual.
* Engineering necessary to produce a drive system that fits and functions with the existing clarifier.
* Freight and delivery to the Wright Smith Jr., Wastewater Treatment Plant located at 1879 Conception
Street Rd., Mobile, AL 36610.
1.4 Base Bid Limits
The base bid is for engineering, manufacture, furnishing, and delivery only. Removal of the existing drive,
installation of the replacement drive, startup/checkout services, drive lubricants or oil, disposal of existing lubricants
or fluids, unloading, field finish or touch-up painting, electrical disconnection or installation, and alteration of the
existing electrical supply are not included unless specifically added by written addendum or separate bid item.
2. BIDDER RESPONSIBILITIES
2.1 Complete and Compatible Supply
The bidder is responsible for furnishing a complete drive system that is mechanically, hydraulically, and electrically
compatible with the existing final clarifier and suitable for installation without unapproved alteration of the clarifier
structure or mechanism. The bidder shall identify in its bid any component, hardware, adapter, control modification,
or other change it believes is necessary for a complete installation.
IFB 26-050 Replacement Final Clarifier Drive Unit Page 3 of 7

2.2 Field Verification
Because the replacement drive must fit an existing installation, the successful bidder shall verify all critical field
dimensions, mounting interfaces, connection points, and other information necessary to confirm compatibility before
releasing the equipment for manufacture. Field verification may be performed by the supplier or by a qualified
representative acceptable to the supplier.
2.3 Equivalent Products and Manufacturers
Products from any qualified manufacturer are acceptable provided the bidder demonstrates full compliance with this
specification and compatibility with the existing clarifier. A proposed equivalent shall be suitable for the same
service and shall provide functional performance equal to or greater than the basis-of-design C40DH drive.
References to existing equipment, serial numbers, or original manufacturer information are for fit, function, and
identification only.
2.4 Exceptions and Deviations
Any exception, deviation, substitution, or qualification to this specification shall be clearly identified in the bid
submittal. Failure to identify an exception or required modification in writing shall be interpreted as full compliance.
Equipment, material, control, or dimensional substitutions shall not be made after award without prior written
approval by MAWSS.
3. TECHNICAL REQUIREMENTS
3.1 Clarifier Drive Unit
The supplier shall furnish one (1) complete replacement clarifier drive unit assembly suitable for the existing 126-
foot-diameter C3 final clarifier. The basis-of-design unit is the Ovivo C40DH. The drive shall be new and shall be
furnished as a complete assembly with all manufacturer-required components necessary for proper mechanical
operation.
3.2 Hydraulic Power Unit
The replacement drive shall include a hydraulic power unit with a motor arranged for 460 VAC, three-phase
electrical service. The hydraulic power unit shall be furnished complete with the components normally required by
the drive manufacturer for operation of the proposed drive system. Any required electrical service differing from 460
VAC, three-phase shall be clearly identified as an exception in the bid.
3.3 Digital Torque Monitoring Control Panel
The replacement drive shall include a digital torque monitoring control panel suitable for the proposed drive system.
The bidder shall provide manufacturer information describing the torque monitoring method, display, alarm and
shutdown functions, available output signals or communications, and required field electrical connections.
3.4 Installation Fasteners and Shims
The supplier shall furnish the installation fasteners and shim kit required for installation of the replacement drive.
Fasteners and shims shall be Type 304 stainless steel at a minimum. Any special mounting hardware, adapter
plates, brackets, or other interface components required by the proposed drive shall be included in the base bid
unless clearly identified as an exception.
3.5 Protective Coating
The basis-of-design factory coating system consists of two (2) coats of Tnemec Series N69F epoxy at a total dry
film thickness of 6-8 mils, top coated with one (1) coat of Tnemec Series 73 Endura-Shield urethane at 2-3 mils dry
film thickness. The topcoat shall be suitable for resistance to abrasion, wet conditions, corrosive fumes, chemical
contact, and exterior weathering. An equivalent coating system may be proposed if the bidder documents prove
equal or greater suitability for municipal wastewater treatment plant service.

3.6 Engineering and Workmanship
The supplier shall provide the engineering necessary to manufacture and furnish a replacement drive that fits and
functions with the existing clarifier. Equipment shall be manufactured to approved dimensions and shall be free of
defects that would interfere with installation, alignment, adjustment, maintenance, or operation. The supplier
remains responsible for the adequacy of its proposed equipment and for identifying any required changes to the
existing installation.
