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.
Return Period Analysis grid report export into Info360
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:
- Storm events: Analysis of different return periods, such as 1-year, 10-year, 25-year, 50-year, and 100-year storms
- Hydraulic performance: Evaluation of the hydraulic performance of the drainage system, including flow rates, velocities, and water levels in pipes, channels, and other system components
- Flood risk: Identification of areas within the drainage network that are at risk of flooding under different storm events
- Capacity assessment: Assessment of the capacity of drainage infrastructure to handle various storm intensities and volumes
- Compliance: Verification that the drainage design meets regulatory requirements and design standards for different return periods
- Visualizations: Graphs, tables, and maps that illustrate the performance of the drainage system under different scenarios
- Recommendations: Suggestions for improving the drainage design to better handle future storm events and minimize flood risk
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.
Improvements to buildings
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.
Technical resources and downloading the new update
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.
