DEVELOPMENT OF ANALYSIS A draft analysis is developed by a knowledgeable consultant who, with the assistance of a committee of experts in the field, identifies all the tasks performed in the occupation.
STRUCTURE OF ANALYSIS To facilitate the understanding of the nature of the occupation, the work performed is divided into the following divisions:
A. BLOCK - is the largest division within the analysis and reflects a distinct operation relevant to the occupation.
B. TASK - is the distinct activity that, combined with others, makes up the
logical and necessary steps the worker is required to perform to complete a specific assignment within a "BLOCK."
C. SUBTASK - is the smallest division into which it is practical to subdivide any
work activity and, combined with others, fully describes all duties constituting a "TASK."
Supporting Knowledge and Abilities The element of skill and knowledge that an individual must acquire to adequately perform the task is identified under this heading. Trends Any shifts or changes in technology or the working environment which affect the block are identified under this heading.

VALIDATION METHOD Manitoba Hydro hoisting-equipment operators validated the tasks and subtasks, and applied percentage ratings to the Task Blocks. DEFINITIONS re: POA VALIDATION YES: You perform this subtask.
NO: You do not perform this subtask.
BLOCK %: the percentage of Certification Exam questions that should be devoted to testing the candidates’ knowledge of tasks and subtasks within this particular Block, and relative to all other Blocks. (It is assumed that that the exam consists of 100 questions in total).

SCOPE OF THE OCCUPATION This Provincial Occupational Analysis (POA) identifies tasks performed by the two varieties of skilled workers -- Boom Truck (BT) Specialists and Mobile Crane (MC) specialists – whose activities as power generation/transmission-system personnel comprise the designated-apprenticeable Trade of Crane Operator PGT Crane Operator in Manitoba. These specialists predominantly are cross-trained employees of the electrical-power utility, a provincial Crown agency: i.e. with a few individual exceptions, most of these workers are entrusted with primary duties over and above those of hoisting-equipment operation per se. It is the USC Operators’ achievement to have adapted the stringencies of modern hoisting-equipment maneuver to the particular hazards and precautions of Manitoba Hydro’s corporate-operational environment. These challenges are both unique and highly complex, in keeping with realities of providing an indispensable energy-resource to Manitobans and to other clients within a highly regulated, 21st–century social, economic, and geopolitical surround. Based on the expert testimony of subject matter experts representing both the BT and the MC domains of Hydro craning operations, the POA identifies those characteristics which the two specialist branches of the occupation share, as well as those engagements that distinguish these specialty-branches from each other. This is reflected both in the form and the substance of the POA. At the same time, however, it is stressed that formal categorization of POA task-content also reflects other occupational standards for the hoisting occupations in Canada and in Manitoba more broadly. In short, the detailed content of the POA analyzes PGT craning activity in terms of:
Tasks [Blocks A-C] that essentially adapt core practices from boom-truck and mobile-crane industry practice in general for application to PGT needs;
(e.g., lift-planning, transport of equipment, use of load-chart/technical documents, assembly and set-up procedures, etc.)
Manitoba Hydro specialty tasks [Block D] which BT specialists and MC specialists both perform in common, albeit with some variations arising from differences in equipment and jobsite locations;
(e.g., verifying limits of approach and voltage of nearby powerlines; rigging and hoisting hydroelectric-system components at stations and substation yards, whether by tandem-lift or single-unit configurations and performing tandem a well as conventional lifts, etc.)
Specialty assignments performed either by the utility’s BT operators [Block E], or by those operators who specialize in Hydro mobile crane operation [Block F], respectively.
(e.g., BT-specialty hoisting of smaller-transformers and personnel buckets; MC-specialty hoisting of larger-transformer equipment and clamming-buckets).
As these prefatory considerations may suggest, the work of Manitoba Hydro hoisting-equipment operators’ is deeply shaped by its interplay with leading-edge, 21st-century technological disciplines and technologies, with advances in the engineering as well as the regulation of hoisting equipment, and with the physical and functional idiosyncrasies of individual Hydro installations and hydroelectric system components. A useful if simplistic generalization is that MC Specialists tend to concentrate their efforts at generating stations and converter stations, such as the labour-intensive clearing of water-borne debris that otherwise would clog the turbines of hydro generating-facilities. By contrast, the utility’s BT specialists tend to be more mobile within the corporate environment, concentrating instead on distribution-system assignments, notably with regard to the hoists required for
x
installation/removal and maintenance of sub-station apparatus, as well as the salvage or replacement of steel/wooden line-structures. Similarly MC Operators specialize in such operations as the placing of riprap on dikes, or the installation/removal; of stoplogs and followers at such fixed installations as tailraces, intakes, and spillways, whereas BT Operators typically will spend more time at powerline-project sites, hoisting personnel-buckets, construction materials, and associated system-components. In addition to such technological, regulatory, and built-environment factors, USC Operator’s work is also intensively affected by Manitoba’s extreme climatic conditions, local ecologies, and human geography. Reliance upon ice roads, obligations to honour the entitlements of remote First Nations communities, and the need to secure hoisting jobsites against vehicular traffic when work is proceeding near high-voltage energized lines are just a few of the realities that suggest the practical complexity of the USC Operators’ work-world. Accordingly, much is at stake in ensuring that the training and capabilities of USC Operators is first-rate. Recently, Manitoba Hydro has come to rely heavily upon a groundbreaking mix of competency-based, cross-training practices training and off-site Apprenticeship Technical Training delivered off-site to prepare USC Operators to meet the opportunities and challenges of this work.

BLOCK B
Transporting PGT Hoisting Equipment
Trends: There is a trend toward increasing the personal liability of individual operators in
connection with transport of crane equipment, accompanied by increased
regulatory scrutiny of such detailed technical considerations as load-securement,
tie-downs, and permit requirements, etc. This is associated within significantly
increased requirements for the training of operators to function in a more-closely
regulated world that entails more record-keeping, preparation time,

includes much more advanced provision for shut-offs/cut-offs and for limit-

BLOCK D
Common PGT Hoisting Specialties
Trends: Increased reliance upon engineered lift plans for tandem lifts. Larger and heavier
hoists within the same system-contexts, often resulting in increased site-
congestion, tighter operating spaces, and a heightening of skill/training
requirements among PGT mobile-crane operators and boom-truck operators
alike. Widespread adoption of new materials (e.g. Kevlar and other synthetics) for
fabrication of slings makes some accessories easier to use, but also requires
