The Project Coordinator shall approve any shutdowns of existing water distribution
systems, fire sprinkler systems, domestic water systems or fire alarm systems. Provide
advance written notice at least 14 days prior to the shutdown to the Construction
Coordinator.
3.21
SPRINKLER HEADS
.1
Install and co-ordinate sprinkler head locations with the reflected ceiling plans and
Architectural wall elevations and to ensure adequate coverage.
.2
Heads indicated on drawings are schematic, for purposes of indicating type of heads
only.
.3
[Provide additional heads for defined areas to accommodate future office
partitioning. Maximum head coverage: 175 ft2 in the perimeter zone, and 200 ft2 in
the interior zone.]
.4
Install chrome plated escutcheons for heads flush with wall and ceiling surface.
3.22
TESTING
.1
Provide all labour, material, equipment, etc. as required to carry out testing as specified
herein and as required by authorities having jurisdiction to prove satisfactory completion,
performance and acceptance of all systems.
.2
Testing shall include:
.1
Flow Test
.2
Pressure Test
.3
Inspectors Tests
.4
Pre-action System Tests
.5
Deluge System Tests
.6
Window Sprinkler Tests
.3
Conduct flow tests on water systems as required by authority having jurisdiction.
.4
Pressure Tests
.1
Perform pressure tests on all new or modified piping systems to requirements of
NFPA 13, 14, authority having jurisdiction, and additional requirements noted in
this specification.
.2
All systems shall be pressure tested after final completion. If subsequent
modifications are necessary; e.g. relocation of sprinkler drops or similar minor
revisions, pressure tests shall be repeated as directed by Consultant.
.3
Sprinkler mains and branch piping above new ceilings shall be pressure tested
and all leakage repaired before installation of ceiling tiles.
.4
Final pressure test shall be carried out after installation of sprinklers.
.5
In addition to hydrostatic pressure tests noted above, and operational tests noted
below, all pre-action and deluge sprinkler systems shall be subjected to a
pneumatic pressure test. This test shall be carried out after satisfactory
completion of operational tests noted below. On completion of operational tests,
drain entire pre-action and deluge system including each sprinkler drop leg
(pendant sprinklers). Replace all sprinkler heads and test system under 175 kPa
(40 psig) air pressure for 24 hours. Test shall be considered satisfactory when
observed pressure drop is less that 10kPa (1.5 psig) over 24-hour period.
.5
Inspectors Test
.1
Inspectors tests shall be performed at all dry pipe, pre-action, deluge and alarm
check valve stations, and at all zone stations, flow switches, etc., and at other
locations as required by authority having jurisdiction.
.2
Tests shall prove satisfactory operation of all flow switches and other alarm
devices and all fire detectors connected to pre-action and deluge systems.

.9
Each pre-action, deluge and window sprinkler system shall be subject to a
complete operational test after successful completion of hydrostatic pressure
tests noted above.
.2
Notify Consultant before testing and arrange suitable time for Consultant to
witness test.
.3
When conducting work on the Bannatyne Campus, testing of systems connected
to the 10" fire main looped service will cause Health Sciences Complex fire pump
to run. Notify Owner’s representative prior to performing any work.
.4
For each system, verify that main water valve will trip through every associated
fire alarm detector circuit. Co-ordinate testing with fire alarm supplier when fire
alarm system is being verified. Verify that flow switch for building sprinkler
system annunciates on building fire alarm system each time that main sprinkler
valve is tripped by an associated fire alarm detector circuit.
.5
System control valve shall be open and all other system conditions shall be in
normal "ready" condition. System shall be allowed to flood completely and
pressurize on at least one occasion. Pre-action system shall remain flooded with
water and under normal pressure for a minimum of 24 hours.
.6
Verify correct operation of system and components, and provide test
documentation.
.7
Correct any deficiencies and re-test to satisfaction of Consultant.
.8
Drain entire system after testing, including all sprinkler drop legs.
.9
After replacing all sprinkler heads carry out pneumatic pressure test as noted in
4.4 above for all deluge systems.
Documentation
.1
Section 15500 shall properly document all testing distribute same to all
authorities having jurisdiction, Consultant, and Owner. Testing shall be repeated
as required until acceptable results obtained as determined by authority having
jurisdiction and Consultant.
.2
On completion on inspections and testing submit to Consultant and authorities
having jurisdiction completed signed copies of appropriate NFPA-13 Contractor’s
Material & Test Certificate, Forms 85-A and 85-B.
.3
Refer to Section 01810 for additional documentation details and requirements.
Advance Notice of Testing
.1
Arrange suitable times with authorities having jurisdiction, Consultant and Owner
in advance of all testing so that all have opportunity to witness testing.
Activation
.1
All systems including wet, dry, pre-action, deluge and window sprinkler systems
shall be left in normal active duty condition immediately following satisfactory
completion of testing.
.2
Pre-action systems shall be air charged and set for automatic operation.
.3
Activate pre-action systems even if associated fire alarm interlocks are
incomplete.
3.23
TESTS
.1
Co-operate and co-ordinate with Division 16 for all testing on zoning.
.2
Pressure Tests:
.1
Sprinkler systems; to NFPA 13 requirements.
.2
Standpipe systems; for a period of two (2) hours without pressure loss at 345
kPa (50psi) gauge higher than maximum service pressure, but not less than
1380 kPa (200psi) gauge.
3.24
VALVE STATION (AND COMPRESSOR STATION)
.1
Arrange piping and equipment to provide adequate service accessibility and minimum
space requirements.
.2
