What believers are saying

GHD won 2026 recognition for hydrogen blending, dam removal, smart roundabouts, and Indigenous projects.
Headcount reached about 17,197 in March 2026, and 2026 job postings rose 59.7 percent.
Queensland's ECRi Hub partnership keeps GHD embedded with government-funded innovation and regional commercialization pipelines.

What critics are saying

GHD UK flagged 2025 cuts near 10 percent, hitting environment, contamination, geotechnical, and waste teams.
Integration risk is immediate after Bowman Engineering's May 2026 acquisition; client churn can follow overlapping cultures.
The strongest existential threat is margin compression across commoditized consulting, forcing deeper layoffs and retreat from weaker markets.

Employee-owned GHD bought Bowman Engineering in Texas on May 20, 2026, deepening local transport expertise.
GHD's 165 offices across five continents give it cross-border delivery scale rivals struggle to match.
Its WA100 rank rose from 42 to 39 in 2026, signaling design-market credibility.
