SECTION 1

PROJECT SPECIFIC INFORMATION

1.1 Project Overview

The United States Section of the International Boundary and Water Commission (USIBWC) urgently requires a complete rebuild of one clarifier & one spare drive unit to match existing at the Nogales International Wastewater Treatment Plant (NIWTP), 865 E. Frontage Rd., Rio Rico, AZ, 85648.

1.2 General

This is a firm fixed price contract for the complete rebuild of one clarifier & one spare drive unit, to match existing and any associated and necessary parts. The Government shall not exercise any supervision or control over the Contract service providers performing the services herein. Such Contract service providers shall be accountable solely to the Contractor who, in turn is responsible to the Government.

1.3 Description of Services

This contract is for the complete rebuild and rehab of one concrete Clarifier and one spare Drive Unit.

There is no construction involved. This is only for the refurbishment of the existing of existing clarifier.

The contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items and non-personal services necessary for the complete rebuild of one clarifier, replace & a spare drive unit, to match original condition at NIWTP as defined in this Performance Work Statement except for those items specified as government furnished property, equipment and services. The contractor shall perform to the standards in this contract.

The existing clarifier was built in 2009 as part of the plant expansion project. It has been maintained but it has been operating constantly (24 hours per day, seven days a week) and has experienced normal wear and tear. The gear drive has parts that wear and will need replacing, including, but not limited to, bearings, seals, chains, sprockets, and the motor.

The spare drive unit is disassembled and needs a pinion shaft and pinion gear replaced or have the existing worn pinion gear and pinion shaft rebuilt (welded and machined) to Ovivo specs. All other wear parts need to be replaced with an equal or equivalent to existing, and the unit needs to be reassembled, and a new motor to be installed.

Both drive units are Ovivo Clarifier Drives.

Page-3 of 19

NIWTP will remove the clarifier from service and prepare the clarifier for the project. The NIWTP will drain and clean the clarifier five (5) days prior, allowing the project to commence. Normal drain time is 2-3 days and one more day for cleaning. The Clarifier will be locked and tagged out by the NIWTP for the Contractor to begin the project.

The Contractor must coordinate with the NIWTP to ensure that the clarifier is ready for the Contractor to begin the service on schedule.

Further information on IPP will be provided at time of award.

B. The invoices for this Contract shall not be combined with any other work or other contracts. They shall be for this Contract only.

A. Breakdown each lump sum item into component work activities used in the schedule for which invoices may be requested. The work activities broken out within the Schedule of Values shall be integrated into and made a logical part of the baseline schedule submitted under this section.

1. The total costs for the component work activities shall equal the Contract price for that lump sum item.

2. Overhead, general, and administrative expenses, escrow, bonds, profit, and other across the board markups shall be applied to each line in the Schedule of Values uniformly.

3. An unbalanced Schedule of Values providing for overpayment to the Contractor for items of work to be performed first will not be compliance confirmed but shall be revised by the Contractor and resubmitted until acceptable to the COR. If requested by the Government, the Contractor shall furnish full copies of subcontracts showing actual costs.

4. The Government may request data to verify accuracy of dollar values.

B. Do not break down unit price items. Use only the Contract price for unit price items.

C. An acceptable Schedule of Values shall be agreed upon by the Contractor and COR before the first invoice is processed.

D. The following items shall have an entry in the Schedule of Values. The Contractor may breakdown each item listed into subsections if they so choose. The Contractor may add additional items. The items shown are the minimum required.

1. Mobilization/Demobilization and receiving of parts

2. Installation and aligning/leveling

Attachment A: Training Ovivo circular and mechanism-based clarifiers require routine upkeep focused on cast-iron oil-lubricated drives, torque-monitoring safety switches, and sludge collection components. While a single comprehensive training highlights PDF for every proprietary model is restricted, operation relies on standard preventative maintenance protocols. Training will ensure proper operations and maintenance will ensure a long life and warranty compliance.

Contractor shall provide training for the proper Operation and Maintenance of the OVIVO CLARIFER UNIT. Training shall include the following:

Drive and Mechanical Maintenance

• Oil levels: Check the cast-iron gear housing regularly and change the oil per the specific operation and maintenance (O&M) manual schedule.

• Torque limiter: Test the mechanical or electronic overload/torque alarm monthly to ensure the drive cuts power during high-torque or jammed-rake events.

• Rotation check: Visually verify uniform rotation speed and inspect the main center cage, drive bearings, and pinion/gear alignment.

Sludge and Scum System Checks

• Scraper blades: Inspect rubber squeegees or spiral blades for wear to ensure complete floor scraping without excessive drag.

• Suction risers/valves: For suction-type clarifiers (like C3S models), clear and sample individual riser pipe gate valves to maintain balanced return activated sludge (RAS) withdrawal.

• Scum skimmers: Adjust skimmer blades, beach plates, and flushing water sprays to prevent scum accumulation and pipe clogging.
