Construction & Skilled Trades Labor
Glossary
- Coded (pressure) welder
- A welder qualified to a specific, inspected welding procedure for pressure piping or vessels. Qualification is narrow to a material, position, and procedure, so a welder certified for one job is not automatically certified for another.
- Hiring hall
- A union-operated dispatch system that supplies contractors with pre-vetted, certified tradespeople as jobs demand, and that typically funds and runs regional apprenticeship training. It offers scalable, predictable labor but can be drawn down in a tight market.
- Journeyman
- A tradesperson who has completed a full apprenticeship, accumulated the required supervised hours and coursework, and passed licensing so they can work unsupervised and mentor apprentices. Producing one takes roughly four to five years.
- Journeyman-to-apprentice ratio
- The practical limit on how many apprentices one journeyman can safely supervise, often one apprentice per one or two journeymen. It caps how fast the trades workforce can grow, because training capacity is bounded by the existing workforce.
- Labor reallocation
- The short-run mechanism by which a well-funded project obtains scarce crews: it bids existing workers away from other jobs rather than adding new ones, so wages rise while the total regional stock of qualified labor is unchanged.
- Modular and offsite construction
- Building sections or components of a facility in a controlled factory, then shipping and connecting them on site. It raises the productivity of a fixed workforce and can compress schedules, but depends on utilization, standardized design, transport limits, and interface control.
- Per-diem
- A daily living allowance paid to workers who travel away from home for a job. Rising per-diems and travel packages are a leading sign that a local trades pool is exhausted and a project is importing labor from other regions.
- Vertical short-run supply curve
- A description of trades labor in which added demand produces almost no additional workers in the near term, only higher wages, travel, and overtime, because the training clock and supervision ceiling fix the stock.
