Movement always leaves
vibration and noise behind
Roads, railways and underground spaces connect cities, but they also burden their surroundings. Drawing the line by calculation — how far that burden can be reduced, and where costs start to rise sharply — is the core of mobility engineering.

How Many Decibels Does One More Meter of Noise Barrier Buy?
The limits of attenuation according to diffraction theory. Instead of raising the barrier further, we compare the cost-effectiveness of absorptive surfaces, top-edge shapes and source measures.
Development Next to Railways: Common Sticking Points in Protection Zone Safety Reviews
Excavation depth and setback alone don’t decide the outcome. Case studies on the analysis conditions and monitoring plans that managing authorities actually require.
Bridge Wind Loads: Structures Where Static Calculations Fall Short
Galloping, flutter and vortex-induced vibration in long-span bridges and lightweight roof structures. Criteria for identifying when wind tunnel testing is essential.
Smoke Control and Evacuation Underground: When Ventilation Becomes Life Safety
Where everyday ventilation plans and fire smoke control plans conflict in complexes linked to underground spaces — and how performance-based design resolves it.
Blasting and Pile Driving Vibration Complaints: Measurement Location Changes the Result
Even at the same site, the verdict changes with the choice of measurement points. Designing measurements to verify actual impact — not just to satisfy regulatory limits.
Traffic Impact Assessment and EIA: What You Save by Preparing Them Together
The surveys the two assessments require overlap substantially. A case in which running the procedures in parallel cut duplicate surveys and schedule delays.
