Approve Contractors Before They Start

Contractors start work on our sites before anyone has checked anything. Build me a contractor approval app. Define the approval requirements once, covering insurance with cover levels and expiry, relevant qualifications and accreditations, method statements and risk assessments, references, and any site-specific requirement. Each contractor is assessed against them with evidence attached and each piece carrying its own expiry date. A contractor has a status of Not Approved, Approved, or Approval Expired, and cannot be scheduled onto work unless currently approved, with the check happening at scheduling rather than on arrival. Show me every contractor with their status and anything expiring in the next month. Add an AI agent that reviews a contractor file and lists exactly what is outstanding or expiring, drafts the request for it, and flags where submitted evidence does not actually meet our requirement such as cover below our minimum. Automate three things: a reminder to the contractor before evidence expires, an automatic move to Approval Expired when it does, and an alert if anyone attempts to schedule an unapproved contractor. Two logins: a site manager who schedules and sees status, and a compliance owner who approves.
