About this book
Written for every level of QS practice
From student to senior PQS — the measurement rules don’t change. What changes is the workflow through which they are applied.
Building Quantities Explained by Ivor H. Seeley set the standard for how quantity surveyors learn their trade across five editions from 1965 to 1988. Its trade-by-trade structure, worked dimension paper examples, and careful citation of measurement rules gave a generation of professionals a reliable reference they carried throughout their careers.
This book is written in the same spirit — systematic, trade by trade, with worked examples cited against AIQS SMM rules at every step. The difference is that the dimension paper has been replaced by the Revit model, and the measurement rules are applied by the QSKing extraction engine rather than by scaling a drawing.
The QS still needs to understand why each quantity is taken the way it is. That knowledge does not become obsolete. What changes is the workflow through which it is applied.
AIQS SMM throughoutEvery chapter cites the relevant AIQS SMM rule and shows how QSKing applies it automatically.
Two worked examplesResidential house and multi-storey commercial building — from model to complete BQ.
Revision tracking chapterHow the delta engine handles design changes — orphan warnings, re-linking, and re-export.
Parameter reference appendixComplete reference for all QSKing shared parameters — QTO_PaintFinish, QTO_ExternalFinish, and more.
