Scope boundary: This skill covers external impacts from the works on remaining property (sensory, proximity, business disruption). For structural/configurational loss to the remainder after a partial taking (frontage, shape, access, utilities, farm severance), use severance-damages-quantification. Both fall under OEA s.18.

Construction Period Impacts (Temporary)

Temporary damages during construction period, typically quantified as percentage rent reduction or lump-sum business loss.

Noise Impact Modeling (dBA Levels, Duration, Receptor Sensitivity)

Methodology: Measure noise levels in dBA, assess duration and timing, evaluate receptor sensitivity.

Sound level measurements:

dBA scale: A-weighted decibels (approximates human hearing sensitivity)
Background noise: Typical urban 50-60 dBA, suburban 40-50 dBA, rural 30-40 dBA
Construction noise: Typically 70-95 dBA at 15 meters from equipment
