and fill with water to point of overflow, but not less than 10-foot head of water (30
kPa). From 15 minutes before inspection starts to completion of inspection, water
level must not drop. Inspect joints for leaks.
Finished Plumbing Test Procedure: After plumbing fixtures have been set and
traps filled with water, test connections and prove they are gastight and
watertight. Plug vent-stack openings on roof and building drains where they leave
building. Introduce air into piping system equal to pressure of 1-inch wg (250 Pa).
Use U-tube or manometer inserted in trap of water closet to measure this
pressure. Air pressure must remain constant without introducing additional air
throughout period of inspection. Inspect plumbing fixture connections for gas and
water leaks.
Repair leaks and defects with new materials and retest piping, or portion thereof,
until satisfactory results are obtained.

Cap and subject piping to static-water pressure of 50 psig (345 kPa) above
operating pressure, without exceeding pressure rating of piping system materials.
Isolate test source and allow to stand for four hours. Leaks and loss in test
pressure constitute defects that must be repaired.
Repair leaks and defects with new materials and retest piping, or portion thereof,
until satisfactory results are obtained.

Carry out trench excavation in strict conformity with the Construction Safety Act. Keep
excavation dry at all times.
Excavate and prepare for underground services, so that no portion of any pipe bears
directly against rock or hard surface.
Grade and shape bottoms of excavations for pipes, as required, to fit the lower one-third
segment of pipes and sockets.
Keep sides and bottoms of excavation from freezing and protect as required to prevent
damage to any part of the work by weather or other conditions.
Execute excavating, pipe laying, testing and backfilling in limited length to enable
protective and heating measures to function efficiently.
Break up rocks and boulders removed from excavation as required, to permit handling.
Remove rock encountered by drilling and wedging. Blasting will not be permitted unless
prior written instructions are obtained.
Form bottoms of trenches in earth inside building so that pipes are supported on a solid
bed of undisturbed earth. Lay pipe to relieve hubs or conduits of undue strain. Backfill
excavation required in proximity to and below footing levels with 10 MPa concrete to the
level of the top of adjacent footing. Support piping inside building installed in unstable or
filled ground as defined by jurisdictional authorities on a reinforced 17.5 MPa concrete
pad or piers. Shape concrete support to provide a minimum bearing for the lower
one-third of circumference of pipe.
Support outside piping passing through building foundation walls with reinforced 17.5
MPa concrete pads. Key concrete pads into the outside wall and extend in length
sufficiently to obtain a minimum bearing of .6m on undisturbed ground. Extend and wire
the reinforcing steel of the support pads to the reinforcing steel of the outside walls, to
prevent failure at the junction of the two elements.
Replace excavation carried to greater depth than shown or authorized through
negligence or error, with well compacted acceptable sand fill or concrete, at no change to
Contract Price to give a bearing value equal to that of adjacent soil.
Do not commence backfilling until written instruction to do so have been obtained.
Backfill carefully to avoid injury to work and undue subsequent settlement.
Backfill pipe trenches under building floors with sand placed in 150mm layers compacted
to 98% standard Proctor. Manually compact fill up to 450mm above pipes.
Include for cutting and making good of concrete floors inside building to accommodate
new services. Final floor finish to be provided by General Trades where noted on the
Architectural drawings.
Store materials excavated in locations as instructed and in such a manner as to produce
a minimum of damage or disfigurement of existing ground. Remove and dispose of
excess excavated materials. Leave site clear and unencumbered.

EXAMINATION
Examine areas and equipment to receive vibration isolation and seismic-control
devices for compliance with requirements for installation tolerances and other
conditions affecting performance of the Work.
Examine roughing-in for reinforcement and cast-in-place anchors to verify actual
locations before installation.
Proceed with installation only after unsatisfactory conditions have been corrected.
COORDINATION AND EXECUTION
Coordinate size, shape, reinforcement and attachment of all housekeeping pads supporting vibration/seismically rated equipment. Concrete shall have a minimum compressive strength of 3,000 psi or as specified by the project engineer. Coordinate size,
thickness, doweling, and reinforcing of concrete equipment housekeeping pads and
piers with vibration isolation and seismic restraint device manufacturer to ensure adequate space, embedment and prevent edge breakout failures. Pads and piers must be
adequately doweled in to structural slab.
Housekeeping Pads must be adequately reinforced and adequately sized for proper installation of equipment anchors. Refer seismic restraint manufacturer’s written instructions.
Coordinate with vibration/seismic restraint manufacturer and the structural engineer of
record to locate and size structural supports underneath vibration/seismically restrained
equipment (e.g. roof curbs, cooling towers and other similar equipment). Installation of
all seismic restraint materials specified in this section shall be accomplished as per the
manufacturer’s written instructions. Adjust isolators and restraints after piping or wiring
systems have been filled and equipment is at its operating weight, following the manufacturer’s written instructions.
Isolated and restrained equipment, duct and piping located on roofs must be attached
to the structure. Supports (e.g., sleepers) that are not attached to the structure will not
be acceptable.
Attach piping to the trapeze per seismic restraint manufacturer’s design. Install cables
so they do not bend across sharp edges of adjacent equipment or building structures.
Do not brace or support equipment to separate portions of the structure that may act
differently in response to an earthquake. For example, do not connect a Transverse restraint to a wall and then a Longitudinal restraint to either a floor/ceiling/roof at the
same braced location.

 Application Specific Controller (ASC):
A pre-programmed control module which is intended for use in a specific application. ASCs
may be configurable, in that the user can choose between various pre-programmed options,
but it does not support full custom programming. ASCs are often used on terminal equipment
such as VAV boxes or fan coil units. In many vendors' architectures ASCs do not store trends
or schedules but instead rely upon a Building Controller to provide those functions.
 BACnet/IP:
An approved BACnet network type which uses an Ethernet carrier and IP addressing.
 BACnet MS/TP:
An approved BACnet network type which uses a Master-Slave Token Passing configuration.
MS/TP networks are unique to BACnet and utilize EIA485 twisted pair topology running at
9600 to 76,800 bps.
 BACnet over ARCNET:
An approved BACnet network type which uses an ARCNET (attached resource computer
network) carrier. ARCNET is an industry standard that can utilize several speeds and wiring
standards. The most common configuration used by BACnet controllers is an EIA485 twisted
pair topology running at 156,000 bps.
 Building Controller (BC):
A fully programmable control module which is capable of storing trends and schedules, serving
as a router to devices on a subnet, and initiating read and write requests to other controllers.
Typically this controller is located on the Ethernet/IP backbone of the BAS. In many vendors'
architectures a Building Controller will serve as a master controller, storing schedules and
trends for controllers on a subnet underneath the Building Controller.
 Direct Digital Control (DDC):
A control system in which a digital computer or microprocessor is directly connected to the
valves, dampers, and other actuators which control the system, as opposed to indirectly
controlling a system by resetting setpoints on an analog pneumatic or electronic controller.
 PICS - Protocol Implementation Conformance Statement:
A written document, created by the manufacturer of a device, which identifies the particular
options specified by BACnet that are implemented in the device.
 Smart Actuator (SA):
An actuator which is controlled by a network connection rather than a binary or analog signal.
(0-10v, 4-20mA, relay, etc.)
 Smart Sensor (SS):
A sensor which provides information to the BAS via network connection rather than a binary or
analog signal. (0-10000 ohm, 4-20mA, dry contact, etc.)
 Web services:
Web services are a standard method of exchanging data between computer systems using the
XML (extensible markup language) and SOAP (simple object access protocol) standards. Web

services can be used at any level within a Building Automation System (BAS), but most
commonly they are used to transfer data between BAS using different protocols or between a
BAS and a non-BAS system such as a tenant billing system or a utility management system.
Terms used within the Sequences of Operation:
 adj.
Adjustable by the end user, through the supplied user interface.
 AI, AO, etc. (Column Headings on Points List)
AI = Analog Input. A physical input to the control module.
AO = Analog Output. A physical output from the control module.
AV = Analog Value. An intermediate (software) point that may be editable or read-only.
Editable AVs are typically used to allow the user to set a fixed control parameter, such as a
setpoint. Read Only AVs are typically used to display the status of a control operation.
BI = Binary Input. A physical input to the control module.
BO = Binary Output. A physical output from the control module.
BV = Binary Value. An intermediate (software) point that may be editable or read-only.
Editable BVs are typically used to allow the user to set a fixed control parameter, such as a
setpoint. Read Only BVs are typically used to display the status of a control operation.
Sched = Schedule. The control algorithm for this equipment shall include a user editable
schedule.
Loop = A control loop. Most commonly a PID control loop. Typically a control loop will include
a setpoint, an input which is compared to the setpoint, and an output which controls some
action based upon the difference between the input and the setpoint. A PID control loop will
also include gains for the proportional, integral, and derivative response as well as an interval
which controls how frequently the control loop updates its output. These gains may be
adjustable by the end user for control loop "tuning," but in self-tuning control loops or loops
which have been optimized for a specific application the gains may not be adjustable.
Trend. The control system shall be configured to collect and display a trend log of this object.
The trending interval shall be no less than one sample every 5 minutes. (Change of Value
trending, where a sample is taken every time the value changes by more than a user-defined
minimum, is an acceptable alternative.)
Alarm. The control system shall be configured to generate an alarm when this object exceeds
user definable limits, as described in the Sequence of Controls.
Note: If the specifications require use of the BACnet protocol, all of the above shall be
provided as BACnet objects.
 KW Demand Limiting: *
An energy management strategy that reduces energy consumption when a system's electric
power meter exceeds an operator-defined threshold.
When power consumption exceeds defined levels, the system automatically adjust setpoints,
de-energizes low priority equipment, and takes other pre-programmed actions to avoid peak
demand charges. As the demand drops, the system restores loads in a predetermined
manner.
 Occupant Override Switch, or Timed Local Override:
A control option that allows building occupants to override the programmed HVAC schedule
for a limited period of time.
When the override time expires, the zone returns to its unoccupied state.
 Occupant Setpoint Adjustment:
47
Rev 5, July 12,2013
TORONTO CATHOLIC DISTRICT SCHOOL BOARD
St. Elizabeth Catholic School
SECTION 239994
DIGITAL CONTROLS



A control option that allows building occupants to adjust - within limits set by the HVAC control
system - the heating and cooling setpoints of selected zones. Typically the user interface for
this function is built into the zone sensor.
Optimal Start-Up: *
A control strategy that automatically starts an HVAC system at the latest possible time yet
ensures comfort conditions by the time the building becomes occupied.
In a typical implementation, a controller measures the temperature of the zone and the outside
air. Then, using design heating or cooling capacity at the design outside air temperature, the
system computes how long a unit must run at maximum capacity to bring the zone
temperature to its occupied setpoint.
The optimal start algorithm often includes a self-learning feature to adjust for variations from
design capacity.
A distributed system must use Run on Request with Optimal Start. (See below.)
Requested, or Run on Request: *
A control strategy that optimizes the runtime of a source piece of equipment that supplies one
or more receiving units - such as an air handler unit supplying zone terminal units with heating,
cooling, ventilation, or similar service. Source equipment runs only when needed, not on a
fixed schedule.
The source equipment runs when one or more receiving units request its services. An operator
determines how many requests are required to start the source equipment.
For example, if all the zones in a building are unoccupied and the zone terminal units do not
need heating or cooling, the AHU will shut down. However, if a zone becomes occupied or
needs cooling, the terminal unit will send a run request to the AHU to initiate the start-up
sequence. If this AHU depends on a central chiller, it can send a run request to the chiller.
The run on request algorithm also allows an operator to schedule occupancy for individual
zones based on the needs of the occupants without having to adjust the schedules of related
AHUs and chillers.
Trim and Respond, or Setpoint Optimization: *
A control strategy that optimizes the setpoint of a source piece of equipment that supplies one
or more receiving units - such as an air handler unit supplying zone terminal units with heating,
cooling, ventilation, or similar service.
The source unit communicates with receiving units to determine heating, cooling, and other
requirements, and then adjusts its setpoint.
For example, if all zones are comfortable and do not request cooling, the AHU will gradually
increase (trim) its supply air setpoint. When a zone requests cooling, the AHU responds by
dropping its setpoint. The more zones that request cooling, the more it drops the setpoint. The
AHU repeats this process throughout the day to keep zones cool, but with a supply air setpoint
that is no cooler than necessary.
Contracting Terms:
 Furnished or Provided:
The act of supplying a device or piece of equipment as required meeting the scope of work
specified and making that device or equipment operational. All costs required to furnish the
specified device or equipment and make it operational are borne by the division specified to be

The seismic restraint components provided by Kinetics Noise Control, Inc. are
intended to be used with suspended single supported conduit and trapeze supported conduit, cable trays, and bus ducts. Components intended to both support and restrain distribution systems such as wall mounted conduit, cable
trays, and bus ducts will need to be designed and evaluated for both the dead
weight load and the design horizontal seismic load.
To ensure that the seismic forces are transferred properly to the restraint
points, the cables should be strapped either individually or in bundles to the cable tray at regular intervals. It is necessary for the conduit, bus ducts, and cable
trays to be attached to the trapeze bars sufficiently to resist the design horizontal seismic forces, both transverse (T) and longitudinal (L).
Brace a change of direction longer than 3.7 m (12’).
This specification does not allow the use of the 300,, (12’’) rule where the conduit
and electrical may be exempted from seismic restraint based on the length of the
support rods provided that the rods are not subjected to bending moments.
Install restraint cables so they do not bend across edges of adjacent equipment
or building structure. Tie back to structure at 45 degrees to the structure.
Longitudinal restraints for single conduit supports shall be attached rigidly to the
pipe, not to the pipe/conduit hanger.
For supports with multiple conduits (trapezes), secure conduit to trapeze member
with clamps approved for application.
Where conduit, bus ducts, cable trays sizes reduce below required dimensions
noted above in Section 3.2.F, the final restraint shall be installed at the transition
location.
Rod Stiffener Clamps are required where the hanger rod exceeds the maximum
length shown in the seismic calculation sheets. They are only required at restraint
locations.
Seismically Rated Beam Clamps are required where welding to or penetrations to
steel beams are not approved.
Adjust restraint cables so that they are not visibly slack. Cable not to support
weight during normal operation.
Seismic systems are to be compatible with requirements for anchoring and guiding of systems.
Drilled or power driven anchors or fasteners shall not be permitted for use with
seismic control measures.
Friction due to gravity does not constitute a seismic attachment.
Seismic restraint connections are not to be connected to the bottom chord of
steel joists or the bottom flange of steel beams.
Standard beam clamps can be used to support restrained components; they cannot be used to connect the seismic restraint to the structure – only for the hanger
rods.
Brace remaining electrical components to code requirements (OBC & NBC or TI809-04).
INSPECTION AND CERTIFICATION
Notify the local representative of the seismic restraint materials manufacturer prior to
installing any seismic restraint devices. The contractor shall seek the representative’s

Project Design Overview
This standard is drawn from the ANSI/TIA/EIA Structured Wiring Standards and designed to
support the standards of the Toronto Catholic District School Board. Projects will vary
depending on whether the project is new or retrofit design and construction.
The base facilities required are to include communications equipment rooms (ER),
Telecommunications Rooms (TR) and Pathways for the distribution of the Structured Cabling
System (SCS).
Designated locations for workstation outlets should accommodate room rearrangements and
future alternate uses whenever possible. The workstation outlets should be located so that they
are far away from the main teaching boards, windows, egress and water sources (including
condensation from louvers and equipment.
Every teaching area shall receive sufficient workstation outlets to allow for a minimum of four
cables all other areas shall be provided with a minimum of two cables per location. Offices
require multiple locations to allow for multiple furniture arrangements (2 locations minimum).
Unless fully enclosed in conduit, all communications wire shall be PLENUM rated Category 6
UTP #24 AWG, or better.
All workstation outlets and patch panels shall use ANSI/TIA/EIA T568A 8-pin modular jacks (RJ45) and be generic in design.
All cabling shall be installed in a star topology, originating in the TR and terminating at the
workstation outlet. All conductors shall be terminated at both ends.
Electrical wiring shall not be bundled in the same pathway as the communications wiring unless
the pathway contains partitions for power and communications wiring approved for this purpose.
Combination power and data outlet boxes (typically used in floor installations) shall contain no
cross over wiring.
Fibre optic cabling is to be used between buildings for Data distribution due to its transmission
