Construction output in Belgium fell 0.5% year-on-year in October 2025, marking the first decline in five months after stagnating in September. The drop was driven by a further contraction in civil engineering (-2.6% vs. -2.0% in September), while growth in specialized construction activities slowed (0.4% vs. 1.0%). In contrast, the decline in building construction moderated (-0.8% vs. -2.2%). On a seasonally adjusted monthly basis, construction activity edged up 0.4% in October, rebounding from a 1.2% fall in the previous month.
