14 topics in this discipline
Where concrete volume actually goes — including the parts that are habitually forgotten — and how wastage and batching affect the order.
Also: Civil & Structural
Why formwork is designed for placement rate and temperature rather than the weight of the finished slab, and where the hydrostatic cap applies.
Also: Civil & Structural
Bond-based development length, the Class A and B lap distinction, and what actually controls the length you detail.
Also: Civil & Structural
Waist slab, steps and landing as separate volumes, and why the pour is usually smaller than people expect.
Block counts per square metre, opening deductions, mortar volume and a realistic waste allowance.
Converting area and thickness into wet volume, dry volume and the bag count you will actually order.
How excavation, compaction and bulking change the numbers, and why a balanced site is almost never balanced on paper.
Calculating excavation for trenches and pits including working space, which is usually larger than the structure itself.
Converting area and layer thickness into compacted volume, tonnage and the delivery schedule behind it.
Also: Civil & Structural
Conduit fill percentages by conductor count, the reason they exist, and choosing the next conduit when the first does not fit.
Also: Construction & QS
How far a run grows, why plastics move far more than steel, and when expansion loops stop being optional.
Also: Construction & QS
The path from an engineered quantity to a priced line item, and where quantities get lost between disciplines.
Also: Civil & Structural
Surveying an existing structure so the design assumptions match reality, and the dimensions most often wrong.
Also: Civil & Structural
The checks that matter before concrete is placed, when the formwork is carrying load that will not be there later.
