I am developing an end-to-end platform that pulls live claim-related data from Revit models, runs it through a FIDIC rules engine, and then immutably stores and certifies every step on Hyperledger Fabric. The objective is clear: the moment a potential claim is flagged in the BIM environment, it should be automatically registered, classified, validated against the relevant FIDIC clauses, and published to an auditable ledger—with a web dashboard showing the entire trail in real time. Scope of work • BIM connector: a service that extracts the necessary objects, properties, and metadata directly from Revit (IFC compatibility is a plus) and hands them to the API. • Integration backend (API): a lightweight, well-documented REST/GraphQL layer focused on automated workflows—no manual triggers. It orchestrates data flow, handles authentication, and forwards transactions to the chaincode. • Hyperledger Fabric layer: chaincode that defines the claim data structures, records each state change on the ledger for record-keeping, and exposes smart-contract functions the API can call. • FIDIC rules engine: codify the relevant clauses so each claim is automatically validated and classified; results are written back to the ledger and surfaced to the UI. • Dashboard & reporting: a responsive interface that lists claims, their on-chain hash, current FIDIC status, and an exportable proof file. Charts or KPIs (e.g., claim volume by type, average response time) are welcome. Acceptance criteria 1. A change order tagged in Revit appears on the dashboard in under five minutes. 2. Each lifecycle event is signed and stored on the Fabric ledger, and its transaction ID is visible next to the claim. 3. The “Export Proof” button downloads a JSON file containing the full claim history and Merkle proof that verifies against the ledger hash. 4. Unit tests cover at least 80 % of the smart-contract logic and rules engine functions. Tech stack preferences • Revit API, .NET or Python for the BIM connector • Node.js, Go, or Python for the API and chaincode • PostgreSQL (or similar) for off-chain analytics • React or Vue for the dashboard If you have hands-on experience linking Revit to Hyperledger and translating FIDIC into executable logic, I’d like to see a short outline of your proposed architecture and an indicative timeline for an MVP.
