Division C – Appendix A
A-2.2.1.2.(1) Structural Design. Part 4 of Division B is written on the assumption that structural design will be carried out by a professional who is qualified to perform such design. Sentence 2.2.1.2.(1) is not intended to imply that a professional may not also be required in the application of requirements in other Parts of the NBC BCBC.
A-2.2.7. Professional Design and Review. This Section provides for the use of what are generally called Letters of Assurance. The letters themselves, known as Schedules A, B-1, B-2, C-A and C-B and located at the end of Division C, are intended to put on paper the responsibilities of the owner and various registered professionals of record in a construction project. The Letters of Assurance do not impose any additional responsibilities on the registered professionals nor are they intended to alter the roles and responsibilities of the authorities having jurisdiction.
The Schedules have been very carefully scrutinized by the Province of British Columbia, Union of BC Municipalities, Building Officials’ Association of BC, Architectural Institute of BC, Association of Professional Engineers and Geoscientists of B.C. and their respective legal counsel. The precise wording in the letters is extremely critical and must not be modified. For this reason, authorities having jurisdiction will only accept copies of the original master Schedules as published in Division C. Any notations on these Schedules which are absolutely necessary to suit a particular project must be clearly and legibly marked in pen on the copies.
It is typical that the registered professional responsible for the design is also responsible for the field review. However, tThere are instances where this is not the case and having a different registered professional doing the field reviews is unavoidable a different registered professional is hired for the field reviews. Schedule C-B requires that the registered professional that provides the field review provide assurance that provides assurance that the building as finally constructed is in substantial conformance with the Code. It may be unreasonable to expect a separate field reviewer to take on the responsibility for Code compliance of a design done by others. . It is unreasonable to expect the field reviewer to take on the responsibility for Code compliance of the design done by others. In the event of transition, Schedule C-B must be clarified by the field reviewer by crossing out and initialing Clause (b)(i) and providing the effective transition date. Under such circumstances it is acceptable for the registered professional responsible for the design to cross out and initial the paragraph related to field reviews on Schedule B and for the registered professional responsible for the field reviews to cross out and initial the paragraph related to design and Code conformance.
Note that Schedules A, B-1, B-2, C-A & C-B, as required by Subsection 2.2.7., must be signed and sealed and submitted to the authority having jurisdiction, as applicable for each specific project. Conditional or qualified Schedules are not typically acceptable. Any fire and life safety deficiency that would prevent the issuance of a Schedule must be remedied before the Schedule is released, not accommodated by conditions or qualifications placed on the Schedule. See the Guide to Letters of Assurance, available from the Building and Safety Policy Branch Web site, for more details.
There are a few locations in the Province where building permits are not issued and there is no authority having jurisdiction. In such circumstances, it is recommended that the coordinating registered professional retain the Letters of Assurance with the project documents. The schedules are a valuable record of the registered professionals who assured the building’s substantial code conformance.
A-2.2.7.1.(1)(b) Structural Components. The reference to “structural components of buildings that fall within the scope of Part 4” includes the situation where a building is classified under Part 9 due to its size and occupancy but also contains some structural components (such as beams supporting concentrated loads) which must be designed under Part 4. In this situation only Schedules B-1, B-2 and C-B for the structural components are required. Schedule A and Schedules B-1, B-2, C-A and C-B relating to non-structural components are not required. Refer to Appendix A-9.4.1.1. and A-9.4.1.1.(3) in Division B for structural design of Part 9 buildings for lateral wind and earthquake loads.
A-2.2.7.2.(1)(a) Coordinating Registered Professional. The coordinating registered professional is responsible to ascertain that all Code related aspects which are relevant to the project are clearly identified by each of the registered professionals of record in the collection of Schedules B-1 and B-2. If a registered professional of record has crossed out any item on their Schedule B-2, the coordinating registered professional must confirm this item is not applicable to the project or resolve the issue with the registered professional of record. Only under very unusual circumstances should additional registered professionals within a single discipline be expected to submit Schedules B-1, B-2 and C-B to the coordinating registered professional.
A-2.2.7.2.(1)(b) Schedule B-2. The purpose of Schedule B-2 is to clearly identify the appropriate registered professional of record who has the overall responsibility in each discipline for compliance with the various code-related aspects of the project. Detailed design of certain building components may be undertaken by a second registered professional. It is common in the industry for detailed sprinkler design or detailed structural design of open web steel joists to be performed by a second registered professional who may be retained by the contractor or the fabricator. The registered professional of record fulfills their obligation for overall responsibility of Code compliance as indicated in Schedule B-2 by reviewing the shop drawings which are prepared under the direction of the second supplemental registered professional. Such shop drawings must bear the professional seal and signature of the second supplemental registered professional. Field review of these components can be undertaken by either the registered professional of record or the supplemental second registered professional. In the event that the supplemental second registered professional provides the field review, the registered professional of record must be satisfied that such field reviews have been performed and is ultimately responsible for Schedule C-B.
A-2.2.7.3. Demonstration of the Coordinated Fire & Life Safety Systems. The design drawings and supporting documents must clearly indicate all essential details of the coordinated fire and life safety systems prior to issuance of a building permit. Demonstration of the proper, integrated operation of the fire and life safety systems must be conducted prior to occupancy. The following is an example of the steps required to co-ordinate the installation and testing of fire and life safety systems in buildings.
1.0. General
Referencing Schedule B-2:
- Item No. 1.12 “Functional Testing of Architecturally Related Fire Emergency Systems and Devices,”
- Item No. 3.4 “Functional Testing of Mechanically Related Fire Emergency Systems and Devices,”
- Item No. 4.5 “Functional Testing of Plumbing Related Fire Emergency Systems and Devices,”
- Item No. 5.13 “Functional Testing of Fire Suppression Systems and Devices,” and
- Item No. 6.3 “Functional Testing of Electrical Related Fire Emergency Systems and Devices.”
The coordinating registered professional (CRP) and registered professionals of record (RPRs) must demonstrate that the fire and life safety systems' design has been coordinated prior to the issuance of the building permit. That is, the CRP/RPRs must accumulate and submit the necessary documentation, such as:
- complete drawings,
- schedules,
- schematic diagrams,
- fire alarm system sequencing description(showing coordination between mechanical and electrical fire protection and life safety systems),
- mechanical fire protection and life safety schematic riser diagrams,
- electrical fire alarm riser diagram,
- motor data list coordinated with fire alarm system sequencing,
- other documentation, as appropriate,
to demonstrate that the interface of the fire and life safety systems has been designed and coordinated so that when built correctly they will function as an integrated system. Further, it is intended that when the construction of the fire and life safety systems is indicated by the contractor to be complete, the RPRs/CRP witness the demonstration of the testing of the fire and life safety systems to confirm compliance that the as-built systems function as intended by the design.
The required list of items will depend on the simplicity or complexity of the project. The following is a comprehensive list of items for fire and life safety systems for a complex project which need to be coordinated in order to demonstrate compliance:
Notes: It is the responsibility of the coordinating registered professional (CRP) and registered professionals of record (RPRs) to determine the best method of “how to” demonstrate to the authority having jurisdiction (AHJ) that the fire protection and life safety systems have been coordinated for each project. That is, the method(s) used (i.e., charts, drawings, matrices, tables, etc.) for demonstration purposes should be project-specific and relate only to that project.
It is not the intent of this Appendix material to dictate or produce “checklists” or other prescriptive methods for demonstrating compliance since this is best left to the professional discretion of the appropriate CRP/RPRs.
