Episode notes
Temporary Works Span Entire Project Lifecycles
- A single large project (like the Bay Bridge) contains hundreds of temporary-work engineering challenges from excavation to tower erection.
- Jasper positioned his firm to be the single-call resource covering excavation support, concrete stabilization, crane lifts, and phasing moves.
Temporary Works Is Exceptionally Dangerous
- Temporary works is one of the most dangerous construction disciplines because crews work at the frontier: high, deep, and fast.
- Workers rely on quick engineering decisions while balancing extreme time and cost pressures.
Inspecting Olympic Temporary Structures
- Jasper led design and inspection of 300+ temporary structures for the Olympics including camera towers, bleachers, and support systems.
- He inspected scaffolds on a men's downhill course, riding a snowboard in extreme winds to reach exposed camera towers.
