Why removing temporary works can be riskier than installing them
Removal is not installation run backwards. Load paths change, attention has moved on, and the warning signs arrive late. What UK temporary works guidance requires, and what a well-controlled removal phase looks like.

When the Erection Method Becomes the Project: Span-by-Span at Viaduct Scale
At viaduct scale the erection cycle sets the schedule. Span-by-span erection as a production system, with the Bang Na Expressway as the documented case and an editorial reading of where the commercial exposure sits.

The Contract Boundary No One Defines: Interface Risk in Complex Lifts
Interface risk sits between designer, lifting contractor and main contractor. Why “coordination as required” leaves gaps, and what the UK temporary works framework already says.

Why Lifting Capacity Is Rarely the Real Decision in Heavy Lift Planning
Capacity is the least ambiguous part of a heavy lift decision and tends to be fixed first. Why sequencing, interfaces and schedule exposure decide outcomes, with Perdido and Saint-Nazaire.

Why the Transition Can Be Riskier Than the Lift
The lift is the visible event; exposure can gather in the transition, when load, geometry, tolerances and responsibility change at once. With Beijing, Millau and Koror–Babeldaob.

When Temporary Works Stay in Place Too Long
Temporary works are planned for an expected period of use as well as a load. Why exposure can change when they stay longer than planned, what HSE guidance says, and where projects show the dependency.

Weather Windows: Why Wind Doesn’t Delay Heavy Lifts the Way People Think
A wind limit is a number; a weather window is an operation, including contingency and abort time. How marginal forecasts can prolong standby, with Skarnsund and Perdido.
