EQUIPMENT/ SYSTEM TESTING CERTIFICATION

Schedules:

1. The Pre-Startup Meeting shall be held at least ten (10) working days prior to
the startup of the first piece of equipment supplied under the Contract. At that
time, the Contractor shall present his plan as detailed in the previous Part D
"Submittals" and review Engineer's comments and concerns associated with
the general features of each piece of equipment which must be demonstrated.

2. Contractor shall provide Engineer with at least 72 hours notice of his desire to
perform Certified Equipment Testing and/or training to allow necessary
coordination with Owner representatives. Contractor shall be responsible for
any and all coordination necessary with the daily operations of the facility to
accommodate his testing schedule. Actual date and time for testing and/or
training will be the first mutually acceptable date and time available to all
parties subsequent to receipt of the request.

3. Operator Training may be conducted concurrently with the Certified
Equipment Testing with prior approval of the Engineer. However, under no
circumstances will conditions of the testing interfere with the ability of
Owner's representatives to observe necessary features, to hear and understand
instructions, or to ask questions. Under such conditions, and as deemed
necessary by the Engineer, Operator Training will be conducted separately
from, and subsequent to, the Certified Equipment Testing.

PART 2-PRODUCTS (NOT USED)

PART 3 - EXECUTION

3.1 EQUIPMENT STARTUP

A.

Equipment startup shall be performed by a duly authorized representative of the
manufacturer, who is fully trained in the installation, startup and operation of the
equipment, including, but not limited to, drive system alignment, equipment
calibration, and other mechanical or electrical components of the equipment.

The equipment startup shall be performed prior to equipment certification testing

and Operator Training.

No form of energy shall be applied to any part of the system prior to receipt by the

Engineer of a certified statement of approval of the installation from the Contractor.

This certification shall contain a statement by an authorized representative of the

equipment manufacturer that the equipment is ready for testing, as outlined below.

As part of the equipment startup, the Contractor shall:

1. Verify that the equipment is installed properly and in accordance with
manufacturer's requirements and instructions, and as such, it is appropriate to
apply power to the units in question.

2. Verify that all manual, automatic and safety control features of the equipment
functions properly, including all alarm, activation and deactivation sequences.

3. Verify that the equipment can operate without excessive noise, vibration,
overheating, overloading, jamming, etc. during normal operating conditions.

4. Check amperage draws on all power feeds with equipment running under
normal operating conditions.

Each piece of equipment shall be tested sufficiently to ensure that all features

required to be demonstrated and/or verified during the equipment certification

until the unit is fully capable of passing the equipment certification testing.

Where multiple units are provided, each unit shall under go startup procedures.

The Contractor shall provide all power, chemical, tools, equipment, labor, water

fuel, coordinate with Owner to ensure availability of sludge, etc. as required for

startup.

1. The Contractor shall be responsible for all contacts and arrangements as
necessary with the proper municipal departments and/or public utility
companies to arrange for temporary and/or separate billing so that bills
associated with testing and startup procedures can be easily identified.

2. Contacts and arrangements with the local power company shall include, but
not be limited to, all arrangements as necessary so that peak power demands
incurred during testing and startup procedures will not become a part of the
permanent record for determining future power demand charges for the
Owner.

environmentally acceptable manner at no additional cost to the Owner.

The manufacturer representative shall fill out the equipment certification form

included at the end of this Section. Startup will not be considered complete until

this form has been provided to the Engineer.

3.2 CERTIFIED EQUIPMENT TESTING

A.

Certified Equipment Testing shall be performed after the equipment startup testing
is completed and it has been verified that equipment functions in accordance with
the requirements of the Contract Documents in all aspects. It is required that a duly
authorized representative of the manufacturer, who is fully trained in the
installation, startup and operation of the equipment, be in attendance for the

Certified Equipment Testing.

Certified Equipment Testing shall not be scheduled concurrently with the

equipment startup without the prior approval of the Engineer. In all cases, if the

Engineer has arrived on-site for the scheduled Certified Equipment Testing and the

equipment is not capable of demonstrating complete compliance with the Contract

Documents, or if the manufacturer's representative is not present, the Contractor

shall be responsible for all costs to the Engineer associated with failed testing,

including travel expenses. The importance of prior and proper equipment startup
demonstrations to verify the requirements of the Certified Equipment Testing is
stressed.

At a minimum during the Certified Equipment Testing, the Contractor shall

demonstrate to the complete satisfaction of the Engineer the following:

1. That the equipment is installed properly and in accordance with
manufacturer's requirements and instructions, and as such, it is appropriate to
apply power to the units in question.

2. That all manual, automatic and safety control features of the equipment
functions properly, including all alarm, activation and deactivation sequences.

3. That the equipment can operate without excessive noise, vibration,
overheating, overloading, jamming, etc. during normal operating conditions.

4. Amperage draws on all power feeds with equipment running under normal
operating conditions.

of one day (8-hour days, not including travel time) of combined training and
operational assistance for plant operators for each piece of equipment in the proper
operations of provided equipment, and in the techniques, methods, schedules, etc.
associated with maintenance.

The level of the training and operational assistance provided shall be as required to
ensure proper understanding of the equipments operations, maintenance and
warranty conditions. Should manufacturer require time in addition to the
minimums indicated herein, or within the individual specification sections, to
sufficiently detail the proper operations and maintenance of the equipment, it will
be provided at no additional cost to Owner. Under absolutely no circumstances
shall warrantees become void due to Owner's failure to follow operational and
maintenance procedures which were not fully detailed and described to Owner's
representatives during these sessions.

At the Owner’s discretion, the training sessions may be video recorded for the
Owner’s future use.

Refer to individual equipment specification sections for further requirements.
