1.1 

Glued-laminated timber (Glulam) is an engineered wood product requiring precise manufacturing at all stages of fabrication. The finished product can only be tested under laboratory conditions; therefore, quality control of manufacturing is necessary to ensure that the properties of Glulam are commensurate with the specified strengths assigned to Glulam in accordance with CSA O86.

This Standard outlines requirements for the qualification of shop manufacturers of laminated structural timber that is pressure-glued using clamps or mechanical means other than nailing. Qualification requirements for block-glued and re-glued Glulam are covered in Annexes B.1 and B.2, respectively.

1.2 

This Standard outlines requirements for determining the initial and continuing suitability of a plant’s personnel, equipment, and procedures to manufacture structural glued-laminated timber in accordance with CSA O122.

This Standard qualifies individual plants. If more than one plant is operated by one fabricator, each plant requires separate qualification.

The process of glue laminating using mobile or temporary facilities is not covered by this Standard.

1.3  

Certification of Glulam is not covered by this Standard. The manufacture of Glulam is covered by CSA O122.

1.4

1.1 This Standard covers Electric vehicle charging equipment with vehicle-to-grid function, bidirectional power transfer that could be installed in accordance with the Canadian Electrical Code Part I (CE Code Part I, 
C22.1) and the National Electrical Code (NEC), NFPA 70; and intended to assist in the management of the power flow from plug-in electric vehicle back to the grid in an effective and efficient manner. 

1.2 This standard will address electrical safety, interoperability of electric vehicle charging equipment with V2G function for a better grid support and communication between electric vehicles and grid.  

1.1 Inclusions

Several aspects of physical infrastructure were considered here, including the structural requirements for pavements and bridges; the quality and uniformity of traffic control devices (TCDs); and the changing demands of intelligent transportation system (ITS) devices with respect to adding new field equipment to facilitate vehicle-to-infrastructure communication. As such, the physical infrastructure to be covered under this guidance document can be categorized as:

·  Hard infrastructure (e.g., pavements and bridges),

·  Traffic control devices, and

·  Field equipment to support vehicle-to-infrastructure communication.

1.2 Considerations

This document is based on the current state of practice, which is in an early and developmental state.  There have been dozens of field demonstrations and early deployments to support advancing vehicle technologies, which continue to evolve and become more functional.  Additional collaboration between the roadway infrastructure and CAV industries (as well as other stakeholders such as researchers) will lead to new innovations and opportunities that are not yet fully understood. 

Users of this document should consider the timing differences between infrastructure enhancements, which can take several years to complete, versus vehicle evolution which happens at a quicker pace the infrastructure changeover versus the technology industry which moves even faster.  It is safe to assume that CAVs and human led vehicles will share the roadways for decades to come.  Therefore, if a policy change is made to upgrade or enhance an aspect of the physical infrastructure, considerations of the specific upgrade or enhancement should include current CAV technology as well as the next generation.  In addition, the roadway infrastructure owner should also consider the impacts from a design, construction, operation, and maintenance perspective.  The life-cycle differences between infrastructure changeover and CAV technologies are an important aspect of preparing roadways for CAVs. 

The roadway network has been designed for the conventional road user – a human driving a conventional vehicle without CAV features.  As the roadway evolves to accommodate safe deployment of CAVs, any CAV-supported changes to specific physical infrastructure assets must consider the impact of the human driver.  It will be decades or more where both human-led vehicles and CAVs will share the road network.  During this transitional period, upgrades or changes to the physical infrastructure assets should support both the conventional road user as well as CAVs. 

From a high level, one of the most common requests from the CAV industry regarding the roadway physical infrastructure is consistency and uniformity.  Consistency of application and uniformity of appearance.  Ideally, these topics would be coordinated globally but that level of harmonization is difficult and not likely.  Therefore, regional standards (by country) can be helpful to facilitate as much consistency and uniformity as possible. 

Finally, the material in this document is as fresh as possible during the time of the authorship.  However, the document will grow stale and need to be regularly updated as the topic area matures.

1.1.1    Scope of Guideline

This Guideline applies to the design, evaluation, and structural rehabilitation design of standalone pedestrian, cycling and multiuse bridges in Canada.  The Guideline also includes technical clauses related to geometric design, accessibility, safety, durability and sustainability. 

There is no limit on span lengths, but this Guideline does not necessarily cover all aspects of design for every type of long-span bridges. This Guidelines also covers the design of appurtenances such as ramps, stairs, that are structurally connected to the pedestrian, cycling and multiuse bridges.

The provisions contained herein are to be used in conjunction with CSA S6 as this Guideline is not a standalone design document and will in many cases refer to CSA S6 and other standards and specifications.

For pedestrian bridges not entirely within the scope of this Guideline, the clauses specified in this Guideline apply only when appropriate.  Necessary additional or alternative design criteria are subject to approval by the owner.

1.1.2    Scope of this Section

This Section specifies general requirements that need to be considered when applying this Guideline. The provisions in this Section cover the scope and applicability, design philosophy, terminology and reference publications, abbreviations, symbols and definitions. The definitions in this Section are applicable throughout the Guideline.

This Section also includes climate change provisions and introduces aesthetic considerations.

1.1.3    Bridge users

This Guideline applies to pedestrian, cyclist and multiuse bridges as well as other users of bridges including but not limited to equestrians, skiers, and maintenance and emergency vehicles. The provisions for these other users may not be fully defined within this Guideline. Where provisions for a specific user is not included in these Guidelines, engineering judgement and/or reference to other codes and standards shall be used.

Commentary:

The focus of this Guideline is on pedestrians, cyclists, and users with reduced mobility. Due to the large weight, emergency vehicles should apply only in unique applications and where specified by the owner. Maintenance vehicle loading shall be in accordance with Section 3.

1.1.4    Accessibility

The minimum requirements stated in this Guideline are intended to accommodate a range of users including those with reduced mobility. These may be waived or modified when approved by the owner. Refer to Section 2 as well as local codes and standards having jurisdiction.

Commentary:

Pedestrian bridges located in rural or remote areas may not require all Accessibility requirements outlined in Section 2. The surrounding built environmental should be considered.

1.1.5    Bridge components and types

In addition to Clause 1.1.1, this Guideline is intended for the following stand-alone bridge types (e.g. not structurally supported on, above and below by a highway or railway bridge) and bridge components:

beam type bridges;

arch bridges;

cable-supported bridges;

buried bridges;

pre-fabricated bridges; and

stairs and ramps structurally connected to bridges

1.1.6    Exclusions

This Guideline is not intended to apply to the following:

vehicular bridges which also support designated walkways for pedestrians, cyclists and other non-vehicular users (refer to CSA S6);

underground and buried structures such as tunnels;

bridges, approach ramps, and stairs structurally connected to buildings; and

marine structures, e.g. docks, dock ramps, wharfs and jetties

Commentary:

Draft Amendment to C22.1

Draft Amendment to C22.1

1.1    Introduction

This Standard describes the test procedures, test set-ups, and calculations required to determine the performance, capacities, energy consumption, and overall efficiency of gas-fired and oil-fired combined radiant space and water heating systems (combos) with hydronic heat distribution.

1.2    Type of standard

This Standard establishes laboratory methods for testing and rating the thermal performance and electrical energy use of a combo using a consistent test set-up and the same ambient temperature and control settings for all function tests.

1.3    Performance rating

In this Standard the performance of a combo is characterized by a thermal performance descriptor that consolidates measurements for space heating and water heating to provide an annual thermal performance rating, the Thermal Performance Factor (TPF). The water heating load that is incorporated into the thermal performance rating is standardized and the space heating load used in the overall rating is based on the rated space heating capacity of the combo.

1.4     Applicability

This Standard applies to hydronic packaged combo systems and combo designs/configurations with heat inputs up to and including 87.9 kW (300 000 Btu/h) for boiler-based systems and a maximum input up to and including 73.2 kW (250 000 Btu/h) for water-heater-based systems that are intended for field assembly.

The combo system, which is to be tested, is everything from the heat generator hydraulically to the radiant distribution manifold, including all pumps, controls, actuating valves, mixing valves all of which will be provided by the integrator in a kit.

1.5     Types of combo system covered

The following categories of combo systems are covered in this Standard:

a)     Type A System: a combo with a fixed capacity for space heating (Single Stage or On/Off Control);

b)     Type B System: a combo equipped with controls that automatically adjust the space heating capacity based on the space heating load (Modulation or Modulating Control); and

c)      Type C System: a combo with a thermal storage tank or equivalent that decouples the space heating load from the burner control.

1.6     Combo systems not covered by this standard

This Standard does not apply to

a)     electric- and solar-based combo systems;

b)     solid-fuel-based combo systems; and

c)      multi-family dwellings with a central heating plant.

1.7     Units used

The requirements of this Standard are expressed in SI units. The US customary values in parentheses are approximate and for information only.

1.8     Wording and supporting information

In CSA standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.

1.1 General

1.1.1 Application

This Standard applies to hyperbaric chambers that have as their primary function the subjection of humans to pressure environments exceeding 1 atmosphere absolute, such as those required in diving operations; work under compressed-air conditions;

medical treatment;

training; and

research.

1.1.2 Minimum requirements

This Standard establishes minimum requirements for the

operation;

use;

design;

construction;

maintenance; and

testing of all hyperbaric chambers.

1.2 Classification of human occupancy hyperbaric chambers

1.2.1 General

This Standard addresses the following classes of human-occupancy chambers:

chambers used for clinical Hyperbaric Oxygen (HBO) treatment and/or for research purposes;

chambers used for occupational diving operations;

chambers used for tunneling and caisson operations; and

hyperbaric chamber systems in support of offshore diving operations.

1.2.2 Chambers used for clinical HBO treatment and/or research purposes    A clinical HBO chamber is a hyperbaric facility that is overseen by a trained safety director and a Level 2 or Level 3 hyperbaric physician, licensed in the jurisdiction in which they practice medicine, who adheres to the Standard of practice as set out by the Canadian Undersea and Hyperbaric Medical Association (CUHMA). Refer to Clause 17 for requirements applicable to research facilities used for human-subject research.

1.2.3 Types of hyperbaric chambers

1.2.3.1 Single-occupancy chamber

A single-occupancy or mono-place chamber is a hyperbaric chamber normally intended for the treatment of one person and capable of oxygen or air pressurization to a depth not exceeding 20 msw (66 fsw) for the provision of hyperbaric oxygen therapy, normally for clinical applications only.

1.2.3.2 Stationary (multiple-occupancy chamber)

A stationary chamber is a multiple-occupancy or multi-place hyperbaric chamber permanently installed in a vessel, platform, or shore-based facility and fixed to a permanent foundation, i.e., the vessel, platform, or building in which it is housed.

Note: Single lock multiple-occupancy stationary chambers may fall within this category.  This is to be approved by the AHJ

1.2.3.3 Transportable deck decompression chamber (DDC) for occupational diving/hyperbaric operations in support of tunnel construction

A transportable deck decompression chamber (DDC) is a multiple-occupancy hyperbaric chamber with two locks (compartments) that can operate to transfer personnel in and out of the main lock while maintaining pressure of the main lock; and  be moved to a diving or caisson site to support on-site operations.

This chamber may be temporarily set up as a stationary chamber during the period of a contract requiring hyperbaric support.

Note: These chambers are used for emergency pressure related ailment and/or for surface decompression procedures. They conform to the requirements stated in Clause 5.2 of CSA Z275.2 and are designed to operate at pressures of 6 ATA or greater.

1.2.4 Evacuation chamber

An evacuation chamber is a single- or multiple-occupancy hyperbaric chamber that has as its primary function the emergency transportation under pressure of an individual at risk of, or suffering from, a pressure-related ailment. It has a minimum pressure rating of 3 ATA. This sub-class also includes hyperbaric rescue craft (designed in accordance with IMCA D 053) and hyperbaric stretchers (see Clause 11.7).

1.2.5 Submersible compression chamber

A submersible compression chamber (SCC) is a hyperbaric chamber that is capable of transporting personnel, at elevated pressures, from the surface to an underwater site and vice versa.

1.3 Hazards

The Standard addresses special hazards associated with the

design;

construction;

operation; and
