What problem does it solve? Construction project teams often miss critical compliance deadlines such as construction permit expirations, completion filing windows, warranty period ends, and wage deposit refund deadlines, while also failing to track new regulations and local penalty cases that signal enforcement risks. ## Core Features & Use Cases - Compliance Calendar Generation: Automatically builds a reminder calendar from project milestones and certificate validity periods, covering permit expiry, completion filing, warranty deadlines, and wage deposit refunds. - Regulation Change Alerts: Monitors newly issued or revised laws and regulations, filters them by the project's current phase, and pushes change summaries with impact analysis. - Local Penalty Case Push: Tracks administrative penalty disclosures from local housing, safety, and environmental authorities to provide deterrent warnings with fine amounts and legal bases. - Use Case: A project manager enters the milestone plan and certificate dates; the system then sends tiered reminders 30/15/7/1 days before each deadline and alerts the team when a revised construction quality regulation takes effect. ## Quick Start Generate a compliance calendar for my construction project based on these milestone dates and certificate expiry dates, and alert me to relevant regulation changes and local penalty cases.
