Construction documents are rarely read at a quiet desk
They are used among noise, glare, interrupted attention and several urgent questions. Human limits are part of the delivery environment.
Legible type, clear hierarchy and restrained density are not graphic niceties
They help essential information survive the difficult day when the reader is tired and the next trade is waiting.
The design consequence is a clearer hierarchy of information, traceable references and documents that remain usable under real site pressure.
A document respects professional standards by making them possible to follow under real conditions.
