Structure and Organization of RPM and Standards

1 How to Read Standards

1.1 Structure and Organization

1.1.1 Structure of the Roofing Practices Manual Divisions
  1. The structure of the RPM has changed over time. Originally published as a paper-based binder with twelve tabs, it was digitized in 2012 and converted to an online wiki format. In 2016, the wiki-based RPM was restructured to form eight Divisions, A through H.
    Division A: Scope, Use of Standards, and Guarantee
    Division A contains important information about the RPM and the RoofStar Guarantee Program, including any limitations and exclusions applicable to a RoofStar Guarantee.
    Division B: Standards
    Standards are listed by system according to the weather-side surface, and are further divided by system categories - Roof Waterproofing Systems, Water-shedding Systems, and Grade-level Waterproofing Systems. Explanatory notes may be incorporated at the end of each Standard.
    Division C: Accepted Materials
    Division C contains all the listed Accepted Materials used in the RoofStar Guarantee Program; it is searchable by a variety of methods, each made simple by ready hyperlinks.
    Division D: Construction Details
    Division D houses the construction details that support each Standard. Construction Details are categorized by Division and then by System, and each System is then organized by the Part structure with which each Standard is organized.
    Division E: General Information
    Division E contains short articles on related subject matters, and includes reference materials commonly used in design and construction.

1.1.2 Structure of Standards Parts and Sections
  1. Each Standard is divided into fourteen Parts, and each Part is normally divided into three Sections:
    1. Section 1 (General) includes definitions and broadly applicable design guidelines or standards.
    2. Section 2 (Materials) includes specific material requirements within the Part.
    3. Section 3 (Application) includes the requirements, guiding principles, recommendations and ancillary information necessary for the Contractor to build the system that qualifies for a RoofStar Guarantee.
  2. Each section is divided into sub-sections, articles, sentences and clauses. This nomenclature loosely mimics the structure of the British Columbia Building Code and its parent Code, the National Building Code of Canada. The nomenclature of the RPM can be illustrated this way:
Nomenclature Example
Division Waterproofing Systems (Roofs)
System SBS-modified Bitumen Membrane Systems
Standard Standard for SBS-Modified Bitumen Membrane Systems
Section 3.1 Design
Subsection 3.1.5 General Requirements
Article Protected, Modified Protected, and Uninsulated Roof Systems
Sentence …(1)
Clause …(1)(2)
Sub-clause …(1)(2)(3)

1.1.3 Standards Content Use of “and” and “or” between the Clauses and Subclauses of a Sentence
  1. Throughout the Standards, multiple Clauses and Subclauses are connected by the word “and” or “or” at the end of the second last Clause or Subclause in the series. Although this connecting word appears only once, it is meant to apply to all the preceding Clauses or Subclauses within that series. Each connected Subclause ends with a comma to indicate connection. In all cases, a Clause (and its Subclauses, if any) must be read in conjunction with the beginning of the Sentence. Measurements
  1. All values in the RPM and its Standards are given in metric units; Imperial measurements are typically shown in parentheses. Definitions
  1. In addition to the terms defined in the Glossary, the following definitions are used throughout this Manual and in each Standard.
    means the installer of a project. For the purpose of issuing a RoofStar Guarantee, Contractor shall be read to mean an Active Member of the RCABC.
    Design Authority
    means the individual or firm responsible for the issuance of Project specifications and details to which the Project will be bid and constructed. When a Contractor designs a Project, the Contractor is deemed to be the Design Authority.
    means the RGC RoofStar Guarantee Program that issues the RoofStar Guarantee ("Guarantee"); the two terms may be used interchangeably.
    means the Roofing Practices Manual.
    means the scope of work for which the Contractor is responsible. Text Classification
  1. Sentences in a Standard are coloured to classify and differentiate language, to provide clarity of meaning and importance: "requirements", "guiding principles", "recommendations", and "reference" (information):
    are shown in black, and are statements conventionally expressed by "must" or "shall". They convey what is required for the project to qualify for a RoofStar Guarantee.
    Guiding Principles
    are shown in green. Guiding Principles support the requirements and are typically expressed by the use of "should" in the text, but occasionally indicated by "may". Guiding Principles may also pertain to how the RoofStar Guarantee Program is administered. Contained within "Guiding Principles" are Risk Management Best Practices which are binding upon the Contractors who perform work to conform to a Standard.
    are shown in red and are not binding. They are typically expressed with the use of "recommend". While "recommendations" are non-binding, they are nevertheless important, and the reader is strongly urged to adopt them.
    Informative Notes
    are shown in blue and are merely informative and provide useful background material or may explain a standard. Notes are non-binding upon either the Design Authority or the Contractor.
  2. Use of the singular does not exclude the plural (and vice versa) when the sense allows.
  3. The term "standard" and "requirement" have the same meaning.
  4. The term "Standard" (when capitalized) refers to the document (the Standard) that governs the design, permissible materials, and application requirements for a specific system.
  5. Standards are written using a structured numbering system which is explained above.
  6. Italicized text indicates defined terminology. See the Glossary for more defined terms used in this Manual.
  7. Bold italics are used to denote documents or programs of the RCABC and the RGC (Guarantor).
  8. Bold text indicates internal references within a document.

1.2 Images, References, and Material Products

1.2.1 Use of Illustrations and Construction Details Illustrations
  1. Illustrations are offered throughout a Standard, to supplement the text, and are considered non-binding and informative only.
  2. Where an illustration appears to differ from a Standard, the Standard shall be considered binding.
  3. Illustrated materials and applications are representational and therefore any similarity to actual materials or methods, including colours or textures, is purely accidental. Construction Details
  1. Construction Details are located outside of a Standard but may be linked to the Standard within the body of text.
  2. Construction Details may be considered complementary to the Standard and include notes and additional hyperlinks that either direct the reader back to the Standard or to an external document.
  3. Where a Construction Detail appears to differ from a Standard, the Standard shall be considered binding.
  4. Illustrated materials and applications are representational and therefore any similarity to actual materials or methods, including colours or textures, is purely accidental.

1.2.2 Reference Publications Codes and External Standards
  1. British Columbia Building Code (“Code”), current edition.
  2. ASTM International (current edition of standards, as identified in this Manual).

1.2.3 Material Products Materials accepted by the Guarantor (RGC)
  1. Materials identified or described in this Manual and the Standards apply only to those which are accepted by the RGC, unless stated otherwise.

1.3 Editions and Revisions

1.3.1 Digital and Printed Editions Authoritative Version of RPM and Standards
  1. Each Standard is prepared by the RCABC Guarantee Corp. (RGC) Technical Committee, under the final approval of the RCABC Guarantee Corp. (RGC) Board of Directors and is republished every four months.
  2. While printable versions of each Standard are available for download by users of the RPM, the online version remains the authoritative document in all respects and is binding.
