Predict construction delays with Claude, OpenWeather and Slack alerts
Needs changesWhat this workflow does
This AI workflow has 20 nodes and runs when an HTTP POST request hits its webhook URL (plus 1 other trigger). Along the way it connects Airtable, Anthropic Chat Model and Google Sheets. It also calls slack.com over HTTP.
How it runs
Trigger: When an HTTP POST request hits its webhook URL (plus 1 other trigger).
- Load Active Projects (Airtable): search
- Normalize Project Records (Code): runs custom JavaScript code
- Fetch 7-Day Site Weather (HTTP Request): calls an HTTP API
- Fetch Supplier Delivery Status (HTTP Request): calls an HTTP API
- Fetch Crew & Resource Availability (Airtable): search
- Merge: merges the data from its input branches
- Compile Project Risk Profile (Code): runs custom JavaScript code
- Predict Delays with Claude AI (AI Agent): runs an AI agent, with model: Claude AI Model
- Parse AI Delay Prediction (Code): runs custom JavaScript code
- Route by Delay Severity (Switch): routes items into branches
…plus 7 more steps. See the full node list below.
Services it uses
HTTP calls to: slack.com
Before you upgrade to n8n 3.0
1 thing in this workflow is removed in n8n 3.0. Fix it before you upgrade:
- AI Agent v1 (old agent modes) in Predict Delays with Claude AI (v1.6): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
| Removed in 3.0 | Replace with |
|---|---|
| AI Agent v1 (old agent modes) Predict Delays with Claude AI (v1.6) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |

From the author
This workflow monitors active construction projects in real time, ingests weather forecasts, supplier delivery statuses, and crew/resource availability, then uses Claude AI to predict delay risk, estimate schedule impact, and generate mitigation playbooks for…
