Proposed Updates to B.C. Tower Crane Operator Standards
based on the National Occupational Analysis for Tower Crane Operator
(2012)
Background:
B.C. Standards:
Certification Standards for Tower Crane Operators in B.C. were implemented by a
regulation brought into force by WorkSafeBC on March 1, 2011. Six years before that
date, BCACS had started working closely with the stakeholders and representatives of the
B.C. crane industry to design, develop and implement standards for crane operator
certification. In close collaboration with industry, BCACS identified a range of crane
types, sizes and capacities, each requiring different levels of operator knowledge and
skills.
Currently, there are thirteen different crane operator certifications available in B.C.,
depending on the type of equipment and its lifting capacity. All thirteen crane operator
certifications are based on standards developed and maintained by industry through
BCACS. Seven of these (for the larger crane types) are designated as occupational trade
certifications in B.C. and, as a result, are approved by the Industry Training Authority of
B.C. (ITA) for support as apprenticeship training. The remaining six certifications are
approved by BCACS. All thirteen certifications are mandated and regulated by
WorkSafeBC.
Red Seal Standards:
In 2012, the Canadian Council of Directors of Apprenticeship (CCDA) released a draft
National Occupational Analysis (NOA) document. The NOA forms the basis for the Red
Seal standard. The NOA specifies a set of operator certification standards that reflects a
consensus developed among participating provinces (including B.C.). In early 2013, a
gap analysis was performed to compare the existing BC standard with the drafted NOA
(Red Seal standard).

Comparative Analysis Process:
With the assistance of Subject Matter Experts (SME) identified by BCACS, the consulting firm
of North Pacific Training & Performance Inc. (North Pacific) was engaged to review the drafted
NOA document for the Tower Crane Operator trade and conduct a preliminary comparative
analysis with the BC Program Outline for Tower Crane Operator.
Based on the comparative review, North Pacific prepared a Preliminary Gap Analysis Report for
Tower Crane Operator. Working closely with BCACS, North Pacific identified and invited
industry representative SMEs to a working group meeting on February 28, 2013 to review the
standards documents and the Report, to discuss the identified gaps, and to develop
recommendations for alignment of the B.C. standards with the NOA and Red Seal standards.
Results from the SME working group meeting were drafted as potential revisions to the B.C.
standards documents and distributed to the participating SMEs for their review, revision and
final confirmation. Final reviews were completed and compiled by March 31, 2013.
Comparative Analysis Results and Recommendations:
In general, the recommended revisions would have only minor impacts on the existing B.C.
standards. The competencies required for certification and licensing would remain the same, but
details of specific learning tasks and content for several of the competencies would need to be
revised, for example:
clarifying content related to clear communication and communication breakdowns,
adding content related to specific site documentation for operators,
adding content related to luffing jib attachments,
adding content related to multi-crane lifts
adding content related to personnel lifts and associated regulations.
NOTE: If the recommended changes to the Tower Crane Program Outline are approved and
implemented, industry could direct BCACS to facilitate replacing the Tower Crane Operator
certificate of qualification examination with the Red Seal examination, when it is validated and
ready for implementation (possibly in 2015).
