Civil engineering & geotechnics for Géophysique GPR International. QC 50 / CAN 25 / World 25. Region tags: QC Québec · CAN Canada · WORLD. Edition #1 (catch-up). Every item links to its source.
⚡ Highlights
- Québec's PQI 2026–2036 puts $167B on the table — 71% for asset maintenance: a wave of rehab & condition-assessment work on aging bridges, dams, pavements and buried utilities.
- Sensitive Champlain Sea "quick clay" back in focus — one year after the Sainte-Monique landslide, with new ERT resistivity thresholds to flag it before building.
- Marquee QC projects advancing — REM West Island branch open, La Fontaine tunnel rehab, Île-aux-Tourtes bridge, Québec City tramway — and GeoQuébec 2026 comes to Québec City in September.
