91st General Assembly — Madrid

Sustainability Meets Cost Modelling — Environmental Assessment and Construction Cost Models

Assembly

91st General Assembly

Dates

8–10 May 2025

Host

CGATE

What the Assembly was about

Delegates discussed how environmental assessment and construction cost models can be integrated, and what that means for the way construction economists advise clients on heritage, retrofit and new build.

The theme

“Sustainability Meets Cost Modelling” put environmental assessment alongside cost engineering — asking how sustainability targets and budget discipline can work together rather than against each other.

On site

A site visit took delegates through an active construction project in Madrid, connecting the day’s discussion on cost modelling to conditions on the ground.

On the programme

Five presentations looked at cost modelling, sustainability and infrastructure benchmarking.
