24 cards. Read the term and the definition here. The deck at the top of this page is optional.

Grain direction

The orientation of wood structure that influences strength, movement and machining behavior, requiring actual material and load interpretation.

Structural grade

A specified classification and relevant evidence about timber suitability, which cannot be inferred merely from a smooth surface or familiar species name.

Reference face

A selected controlled surface used for marking and relating parts consistently, distinct from an unfinished opposite edge chosen for convenience.

Dry fit

A trial assembly used to check relevant geometry and relationships before final joining, without independently proving every structural or bond requirement.

Service moisture condition

The relevant moisture environment for the timber’s intended use, which affects movement and cannot be replaced by one universal percentage.

Connection load transfer

The actual transmission of forces through joints, fasteners and surrounding wood, requiring design rather than simply more glue or a larger nail.

Thermal resistance

A defined opposition to heat flow in the supplied model, calculated from thickness and conductivity for an appropriate homogeneous layer.

Thermal bridge

A localized pathway of different heat transfer at a junction or material interruption, requiring actual geometry and assembly assessment.

Load path

The route by which actions are transmitted through members, connections and supports to the ground under the actual design conditions.

Moisture-control layer

A specified part of a building assembly managing a relevant moisture route, whose continuity and connections matter beyond the visible finish.

Airtightness

Resistance to unintended air leakage through the relevant enclosure, distinct from deliberately provided suitable ventilation for the building’s actual needs.

Material compatibility

The suitability of interacting materials under the intended load, moisture, movement and exposure conditions, not simply similarity of appearance.

Controlled revision

The approved version of technical information for the actual task, preventing different workers from following incompatible dimensions, details or instructions.

Datum

A stated reference used to relate dimensions and locations consistently, rather than an arbitrary convenient edge selected independently for each part.

Written dimension

The specified physical size or relationship stated on a drawing, distinct from measuring a potentially rescaled printed image with a ruler.

System boundary

The chosen extent of a model or task that determines which inputs, outputs, forces and responsibilities are included in the reasoning.

Measurement uncertainty

A characterization of the possible dispersion associated with a measurement result, distinct from the instrument’s smallest display increment.

Acceptance criterion

A defined requirement used to judge appropriate evidence, which must not be replaced by an attractive appearance or an undocumented expectation.

Hold point

A defined stage requiring appropriate verification or approval before work proceeds and makes the relevant feature difficult or impossible to inspect.

Change control

An accountable process for assessing and approving a departure from specified information, rather than silently substituting a convenient product or method.

Temporary stability

The needed resistance to instability during an intermediate construction stage, which cannot be assumed from the completed structure’s final load path.

Task-specific control

A protective measure selected for the actual hazard, equipment, conditions and competence, rather than a universal glove, distance or generic PPE instruction.

Net quantity

The amount calculated for the defined work before separately specified allowances, which must use consistent dimensions and measurement conventions.

Handover evidence

Relevant records, observations, accepted conditions and unresolved issues communicated to the responsible recipient at completion, beyond a neat visible surface.
