Foundations and slabs
Educational overviews of footings, slabs and foundation walls — what they do, how they're built and where structural and geotechnical input is required.
Building processes, structure and planning
Construction
Construction is the process of turning a plan into a real, lasting building. This section covers the practical concepts behind that process — how foundations transfer load, how walls and roofs work together as a system, what insulation and the building envelope actually do, and how a project moves through phases without losing the plot.
Every region has its own building codes, permit rules and safety standards. The guides here are educational only. Structural, electrical, plumbing, gas and code-related work should be reviewed and executed by licensed professionals.
What you can learn
- How foundations and framing systems carry load
- How roofing, insulation and the envelope work as a system
- How a construction project is phased and sequenced
- When permits, inspections and engineering review apply
- How to read a contractor's scope of work
- How to identify when a licensed specialist is required
