Quantity Survey in Interior Design
Learn to calculate material quantities, prepare BOQs and BOMs, estimate project costs, and manage budgets using practical interior design workflows.
Quantity Survey Summary
Understand the Numbers Behind Every Interior Project
Quantity Survey in Interior Design focuses on measuring, calculating, documenting and estimating the materials and labour required for interior projects.
This module connects interior drawings and site measurements with practical quantity take-offs, procurement lists, quotations and financial planning.
- ✓Understand the role of an interior quantity surveyor in project execution and financial control.
- ✓Calculate quantities for finishes, woodwork, hardware and other interior materials.
- ✓Prepare structured BOQ/BOM documents and project cost estimates.
- ✓Learn to track budgets, wastage allowances and cost variations.
What Will You Learn?
Build the practical skills needed to convert design drawings and site measurements into accurate quantity and cost documentation.
Quantity Take-offs
Measure and calculate interior work quantities using Sq.ft, Rft, Sq.m, Nos and Cu.ft.
Material Calculation
Estimate requirements for flooring, tiling, painting, wallpaper, ceilings, glass and joinery.
BOQ & BOM
Understand the difference between client-facing BOQs and internal procurement BOMs.
Estimation & Costing
Analyse material prices, labour, transport, overheads, taxes and profit margins.
Excel Documentation
Use formula-driven spreadsheets to calculate totals, GST and contingency amounts.
Budget Control
Track project costs and variations while working towards the planned project budget.
