Boring and Lifting: Tunnel Boring Machines and the Safety Elevator

Two machines that move in opposite directions and solve the same problem: making ground and height usable without disturbing what is already there.

Building in Brick and Stone: The Ziggurat, the Corbel and the True Arch

Four milestones in spanning a gap and standing up, using materials strong in compression and nearly useless in tension.

Building Tall: Foundations, the Skeleton Frame and Wind

Four milestones in which building height stopped being limited by structure and started being limited by economics.

Engineering the System: Containerisation, Motorway Networks and Critical Path Scheduling

Three milestones within two years, none of which invented a device. Each fixed an interface or made a hidden structure explicit, and each generated more value than most inventio…

Learning from Catastrophe: Seven Investigations That Changed Practice

Seven formal investigations between 1979 and 2010 that changed engineering practice across industries. In every one, the physical mechanism was known or knowable beforehand.

Long Spans and Hard Lessons: Sydney Harbour, Golden Gate and Tacoma Narrows

Two celebrated bridges and one destroyed one. The collapse taught the profession more than either success, and the mechanism is still widely taught wrongly.

Manufacturing Drinking Water: Seawater Reverse Osmosis and Supply Security

Australian metropolitan desalination turned urban water supply from a hydrological problem into an energy and membrane one, and produced an asset with an unusual duty profile.

Modern Civil Works: Base Isolation, the Channel Tunnel, Cable-Stayed Spans and Supertall Towers

Four milestones showing what changed in civil engineering once dynamic behaviour could be analysed properly and construction method became the primary design driver.

Networks of Movement: Transcontinental Rail, Cable Traction and the Great Wheel

Three projects, three constraints, one lesson: at civil scale the hard engineering is in measurement, power distribution and load path, not in the visible structure.

Roads and Canals: Brindley, Tresaguet, Telford and the Erie

Four milestones in moving goods overland, and a reminder that for bulk freight before the railway, water beat road every time.

Rome: Pozzolanic Concrete, the Aqueduct and the Engineered Road

Four milestones from the civilisation that industrialised construction: a cement that sets under water, gravity supply at metropolitan scale, roads specified to their duty, and …

Sanitary Engineering Matures: Filtration, Disinfection and the Long Aqueduct

Four milestones in which urban water and waste became one system, and in which the profession learned that a treatment barrier can appear to succeed for sixty years.

Spanning the Gap: The Iron Bridge, the Truss and the Suspension Chain

Three milestones in which metal replaces masonry as the primary structural material, and in which someone tests it before building with it.

Stopping a Train: The Air Brake and Fail-Safe Design

Three milestones producing the clearest example of fail-safe design anywhere in this set: a brake that applies itself when its own control system fails.

The Engineering Profession: Competence, Registration and the Duty of Care

Statutory engineer registration began in 1907, the year the Quebec Bridge fell. How the four-pillar competence model works and what it requires of Australian engineers today.

The Gothic Structural System: Ribbed Vault, Pointed Arch and Flying Buttress

Four milestones in which builders working without any theory of statics arrived, by observation and by failure, at a structural system of remarkable efficiency.

Urban Water Engineering: Treatment, Sewerage and Elevated Storage

Three milestones between 1854 and 1860 established the modern urban water system: treat what comes in, separate and treat what goes out, and store enough head to survive a failure.

Water and Mud: Irrigation, Flood Control and the First Engineered Cities

Engineering begins as a response to water. Four milestones in levees, canals, urban drainage and bringing supply inside the walls.

Water, Concrete and Scale: The Panama Canal, Hoover Dam and Prestressed Concrete

Three milestones showing what happens when concrete construction moves from large to unprecedented, and the governing parameter turns out to be hydrology, creep or heat rather t…

Window & Door Hardware — Durability and Corrosion Resistance (ICP-002)

A practitioner's guide to Industry Code of Practice ICP-002 — how the corrosion resistance and cyclic durability of window and door hardware for housing and residential building…
