For external suppliers, companies and testing laboratories

For non-Caltrans companies, testing labs or organizations requiring DIME access, please begin by searching for an existing organization account. If your organization already has an account, please reach out to your organization's DIME account manager and ask to be added. If you could not find your company in the DIME system, you may request that a new DIME organization account be created for you. You must provide a project or contract number and/or specify the reason why you need a DIME account.
