InfoWorks ICM 2025.3 is here with new updates enabling you to export Return Period Analysis (RPA) grid reports and automatically upload them into Info360 Asset. Additionally, improvements to building representation inside of InfoWorks ICM allows for better modeling of LIDs and SuDs. Let’s explore everything that’s new in the latest release.
Inside of the platform, when running RPA reports, you’ll now find a button, “Export Info360”, which is our SaaS platform with next-generation apps like Info360 Asset.
As you likely know, RPA grid reports are comprehensive documents that provide detailed analysis and results of drainage system performance over different return periods (eg, a 1-year, 10-year, or 100-year storm event). The RPA grid report produced in InfoWorks ICM can help you understand how a drainage system will perform under various rainfall conditions.
Within InfoWorks ICM, the RPA grid report will provide you with:
Additionally, in the latest update, Asset ID and Surcharge due to flow variables have been added into the grid report to give you access to more of the data you need.
It is now possible to model the impact of a SuDS or LIDs structure, such as a rain barrel, without using a SuDS control object inside of InfoWorks ICM 2025.2. A new property, Drainage contribution, has been added to a building’s properties. It’s used to specify the percentage of runoff from the roof that enters the drainage system via a building’s “Drains to” object, and is included in the total outflow calculation.
Additionally, a new option, Perimeter, is now available for Exceedance flow type. If selected, any storm runoff from a building’s roof that is in excess of the capacity limit is directed to the boundary of the building and included in the 2D simulation. This lets you model exceedance in the 2D mesh without having to direct it to a node location.
Our technical support team has been hard at work compiling every resource that InfoWorks ICM users could need access to into one central location – the InfoWorks ICM Technical Information Hub. Here, you will find access to version information, training materials, what’s new and feature updates, and plenty more.
