Real Weather Data for Your Acumen Risk Analysis
WeatherWise exports probabilistic weather risk distributions directly into Acumen Risk. Activity-level weather data based on 45+ years of climate records at your exact site.
What is Acumen Risk?
Deltek Acumen Risk (formerly Acumen Risk) is a powerful schedule risk analysis tool used by construction planners and risk professionals to run Monte Carlo simulations on project programmes. It integrates natively with Oracle Primavera P6 and Microsoft Project, enabling analysts to overlay risk assessments directly onto their existing schedules. Acumen Risk is widely adopted on large infrastructure projects where quantitative schedule risk analysis (QSRA) is a contractual requirement.
Risk analysts use Acumen to define risk events, apply duration uncertainty ranges, run thousands of Monte Carlo iterations, and produce tornado charts and S-curve outputs showing probabilistic completion dates. Acumen's schedule health diagnostics also help planners identify logic issues before running the risk model.
WeatherWise + Acumen Risk
WeatherWise exports probabilistic weather risk data in a format compatible with Acumen Risk's import process. Rather than risk analysts guessing weather impact with professional judgement alone, WeatherWise provides evidence-based probability distributions derived from 30+ years of climate data at the exact project location. These distributions slot directly into Acumen's risk model alongside other risk events, ensuring weather is treated as a data-driven input rather than a subjective estimate.
Replace Weather Guesswork in Your Acumen Analysis
Acumen Risk is a powerful QSRA tool, but its outputs are only as good as its inputs. When weather risk is modelled as a single three-point estimate based on professional judgement, the resulting confidence levels do not reflect reality.
WeatherWise provides probabilistic weather distributions derived from 45+ years of ERA-5 climate records at your exact project location. Export directly into Acumen Risk format, and your Monte Carlo simulations finally reflect actual weather conditions rather than assumptions.
How It Works
Four steps from programme upload to data-driven weather risk in Acumen.
Upload Your Programme
Import your project programme from any supported scheduling tool. WeatherWise reads your activities, planned dates, and site coordinates to scope the weather analysis.
Calculate Weather Risk
WeatherWise processes 45+ years of ERA-5 climate data at your exact coordinates. Probabilistic distributions are calculated for each activity based on its weather sensitivities.
Export to Acumen Risk
Export the weather risk data in native Acumen Risk format with a single click. No conversion, no reformatting. Import directly into your Acumen Risk project.
Run QSRA with Real Data
Execute your Monte Carlo simulations in Acumen Risk with weather inputs grounded in real climate data. Produce defensible confidence levels that stand up to scrutiny.
Key Features
Built to provide Acumen Risk users with defensible, data-driven weather inputs.
Direct Acumen Risk Export
Export weather risk data in native Acumen Risk format. Import directly into your project without any conversion tools or manual data manipulation required.
Probabilistic Distributions
Weather risk is expressed as full probability distributions, not simplified three-point estimates. This gives your Monte Carlo engine statistically robust inputs for reliable QSRA outputs.
Site-Specific ERA-5 Data
Weather data is derived from 45+ years of ERA-5 reanalysis records at your exact project coordinates. No regional averages, no generic assumptions, no borrowed data from similar locations.
Activity Granularity
Weather risk is calculated at the individual activity level. Each activity gets its own risk distribution reflecting its specific weather sensitivities, scheduled dates, and seasonal exposure.
Correlation Modelling
Correlations between weather variables are preserved. Wind and rainfall relationships, seasonal patterns, and inter-variable dependencies are maintained for realistic simulation outputs.
Seamless QSRA Workflow
Weather risk data integrates directly into your existing Acumen Risk QSRA workflow. One-click export from WeatherWise, direct import into Acumen, then run your analysis as normal.
