Weather Calendars for Asta Powerproject
WeatherWise exports weather calendars compatible with Asta Powerproject. Import directly into your Asta programme and apply weather-adjusted calendars to activities.
What is Asta Powerproject?
Asta Powerproject is a leading construction project planning and scheduling tool, widely adopted across the UK, Europe, and Australasia. It provides an intuitive Gantt chart interface for creating construction programmes, defining activity logic, managing resources, and tracking project progress. Asta is particularly popular with mid-market contractors and planning consultants who value its user-friendly approach to programme management and reporting.
Construction planners use Asta Powerproject to develop tender programmes, produce baseline schedules, manage look-ahead planning, and generate progress reports. Its built-in calendar system allows planners to define working patterns, but like most scheduling tools, weather calendars are typically created manually using rules of thumb rather than historical weather data.
WeatherWise + Asta Powerproject
WeatherWise generates weather calendars that are compatible with Asta Powerproject's calendar manager. Planners can import activity-specific weather calendars built from 30+ years of location-specific climate data directly into their Asta programme. This replaces guesswork with evidence-based working day calculations, giving planners defensible weather contingency that reflects the actual conditions at their project site.
Data-Driven Weather Calendars for Asta Users
Asta Powerproject is widely used across UK and European construction for programme management. But building accurate weather calendars within Asta means manually marking non-working days based on guesswork and generic allowances.
WeatherWise replaces that guesswork with 45+ years of climate data at your exact project location. Generate activity-specific weather calendars and import them directly into Asta Powerproject's calendar manager.
How It Works
Four steps from your Asta programme to weather-adjusted calendars.
Upload Asta Programme
Import your Asta Powerproject programme file. WeatherWise reads your activities, durations, and site location to understand your schedule structure.
Set Activity Thresholds
Define weather conditions that stop each activity type. Use built-in defaults for common construction activities or customise thresholds to your specifications.
Generate Calendars
WeatherWise processes 45+ years of ERA-5 climate data at your exact coordinates. Each activity gets a calendar showing working vs. non-working days based on real weather patterns.
Export & Import to Asta
Download the generated calendars and import them into Asta Powerproject's calendar manager. Calendars apply directly to activities in your programme.
Key Features
Built for Asta Powerproject users who need accurate, data-driven weather calendars.
Asta Powerproject Compatible
Export weather calendars in a format that imports directly into Asta Powerproject. No conversion tools or manual formatting required.
Activity-Specific Calendars
Every activity in your Asta programme gets its own weather calendar. Earthworks, crane operations, and steelwork each have different weather sensitivities reflected in their calendars.
Direct Import
Import calendars straight into Asta Powerproject's calendar manager. Apply them to activities in your programme without switching between tools or reformatting data.
Programme Structure Alignment
Calendars align to your existing Asta programme structure. Weather non-working days integrate with your existing non-working periods, holidays, and site shutdowns.
Multiple Activity Support
Generate calendars for all activities in your programme simultaneously. Whether you have 10 activities or 500, WeatherWise handles them all in a single workflow.
Update Capability
Regenerate calendars at any point during the project lifecycle. As forecasts update or your programme changes, re-export and re-import to keep Asta calendars current.
