YSTEM

No post-installation test shall be considered complete unless the system and its components being
tested meet, in the judgment of the Engineer, all the material, operating and performance criteria
established in the Contract Documents.

Any system or its components that fail to pass any post-installation test shall be replaced by the
Subcontractor at his own expense until the replacement passes all post-installation tests to the
satisfaction of the Engineer.

If the reason of failure of a system or its components to pass any post-installation test is identified
by  the  Engineer  as  an  equipment  or  system  design  deficiency,  the  Subcontractor  shall  make
necessary  design  modifications  to  that  system  or  its  components  at  his  own  expense,  and  shall
repeat all post-installation tests on the modified system and its components to the satisfaction of the
Engineer.  Engineer shall have the option of rejecting a modified system and/or its components and
requesting  the  Subcontractor  to  supply  at  his  own  expense  a  system  and/or  its  components  of
different design and/or manufacture.  Once the design of a system or its components is modified as
described  above,  such  design  modification  shall  be  incorporated,  at  the  Subcontractor's  own
expense,  into  all  like  systems  and  components,  whether  already  installed  and  tested,  or  to  be
installed in the future.

Subcontractor shall provide and set up all the test equipment necessary for post-installation tests
and shall conduct the tests under the supervision and to the satisfaction of the Engineer.

All costs associated with the post-installation tests shall be borne by the Subcontractor as an
incidental part of his bid price for the system being tested. No separate payment shall be made for
post-installation tests.

No system shall be started-up unless the Engineer issues a post-installation test certificate indicating
that the system has passed required tests to his satisfaction.

Following issuance of the post-installation certificate:

1. The Contractor shall perform a System Start-up and Initial Operation for one month; and
2. The system shall be subjected to a 60-day Reliability Test

Satisfactory passage of any system in post-installation tests shall not relieve the Subcontractor from
any of his responsibilities of system performance under this Contract until a final acceptance
certificate is issued by the Engineer.

f. Traffic Control System

Post-installation tests shall be performed in the presence of

the Employer’s representative on the

following systems, after each system is fully installed and ready for testing and commissioning, as
per the following items:

1. Complete intersection controls including local controller, detectors, signal poles and mast

arms, vehicular signals, pedestrian signals, cable and wiring, and all components, parts
and appurtenances.

2. Complete interconnection (progression) controls along a major artery including master

controller, detectors, communications interface, cable and wiring, and all components,
parts and appurtenances. This also includes additional system detectors.

3. Automatic transfer dual power supply panels, free right turn signals and pedestrian

pushbuttons.

4. Additional Intersections placed under central computer control, including all components,

parts and appurtenances. This also includes performance checking of all
communications cables.

5. Additional loops for traffic violation recording equipment complete.

g. Intelligent Transportation System

YSTEM

1. Production and submission of site acceptance test plans to the Engineer for review and

approval.

2. Commissioning of head-end subsystem equipment (verification of function for a particular

piece of the ITS Platform equipment)

3. Functional verification for one field installation of each subsystem field equipment type

installed. All aspects of the manufacturer-supplied IDDs shall be verified for one complete
communications interface of each subsystem field equipment type.

4. End to end testing shall be conducted as a part of the acceptance test.

Subsystem equipment site acceptance testing shall be exhaustive and performed in a manner so as
to not disrupt the ongoing work of the traffic management centre.

h. Certification of Results

Subcontractor shall notify the Engineer when the site acceptance tests are to be undertaken.

Subcontractor shall forward to the Engineer duly certified copies of the results when the tests have
been successfully completed.

When the Engineer has received these test results, and is satisfied the site has passed the tests,
the Engineer and/or the Owner will notify the Subcontractor/Contractor in writing that the site has
passed the site acceptance test.

Prior to acceptance and commissioning of the systems, system design document shall be developed;
which shall encompass all of the revisions and details pertinent to the actual development and
implementation of the systems, including a revised requirements compliance matrix.

If the Engineer/Owner decides the site equipment is not in accordance with the Contract, he may
reject the equipment at the site, and he will inform the Subcontractor/Contractor of the reasons in
writing.

i. Commissioning of Subsystem Field Equipment

In the case of all subsystem field equipment, following shipment of equipment to the Project location,
all head-end subsystem equipment pre-loaded with the relevant software application programs or
simulations shall be inspected and tested at the

Subcontractor’s facility to verify that equipment is

working prior to installation on site.

j. Approval for Commencement of Integration and Reliability Tests

Engineer will notify the Subcontractor in writing of outstanding faults detected during the
commissioning of In-station equipment tests and defects detected during or after these tests.

Subcontractor shall prepare proposals for rectifying defects and the additional tests to be conducted
after defects are rectified. Proposals shall be submitted to the Engineer for approval.

All defects detected during or subsequent to the commissioning tests shall have been rectified and
successfully passed their tests prior to site acceptance for any site.

k. Reliability Test

Upon successful completion of the post-installation test and commissioning, the system components

are subjected to a 60-day reliability test. During this test any system failure is considered to have
reset the 60-day time-period to zero. Determination of which failures constitute a system failure is at
the discretion of the Engineer and the Owner.

Reliability Testing shall be conducted on all components, systems, and functions affected, changed
or installed, including but not limited to:

YSTEM

l. System Start-up and Initial Operation

Following the issuance of a post-installation test certificate by the Engineer, the Subcontractor shall
start-up the system that passed the post-installation tests, and shall continuously operate the system
for an initial operation period of one month.

Engineer and the Owner's personnel shall be present at the start-up and initial operation of all
equipment, components and systems.

During  the  initial  operation  period  the  Subcontractor  shall  continuously  observe  and  monitor  the
operation  of  the  system  and  shall  make  final  adjustments  and  corrections  to  the  system  to  the
satisfaction of the Engineer.  If during the initial operation period major system and/or component
defects are identified which,  in the judgment of the Engineer, require modifications to the system
and/or its components, the initial operation period shall restart following the completion of the subject
modifications to the satisfaction of the Engineer.

m. Conditional Acceptance

When a system, started-up and initially operated according to the requirements of  Sub-article l of
Article 9.6.3.1, above, performs to the satisfaction of the Engineer during the initial operation period
of one month, the Engineer shall issue a conditional acceptance certificate to indicate that the subject
system  has  been  conditionally  accepted.    Conditional  acceptance  certificate  shall  relieve  the
Subcontractor  from  his  responsibilities  concerning  the  performance  of  the  system  except  for  the
Subcontractor's operation and maintenance responsibilities as described in Sub-article c of Article
9.6.5.

9.6.4
