Summary
You sign a non-disclosure agreement digitally via ValidSign after attempting to open the documents via a Request for Proposal or the project overview. You can sign yourself or authorize a colleague. After signing, the documents are released immediately or after manual approval by the General contractor.
Terms and Target Audience
This article is intended for subcontractors who have been invited to a confidential project. You need a valid email address for the verification step and, if you are signing on behalf of your company, the appropriate signing authority.
Step 1: Start from the request or 12Build
There are two ways to access the non-disclosure agreement:
-
Via the Request for Proposal (email): Click on Download ZIP or View Documents. You will be redirected to 12Build, where a notification immediately appears stating that a signature is required.
-
Directly in 12Build: Navigate to the Documents tab of the relevant project. You will immediately see the lock icon with the option to sign.

Step 2: Sign it yourself or have someone else sign it
In the ValidSign screen, choose who is authorized to legally bind the declaration:
-
Sign yourself: Are you authorized? Click the Send email verification button.
-
Have someone else sign: Are you not authorized to sign? Select another recipient from the list or manually enter your colleague’s name and email address. Then click Send email verification.
Step 3: Sign the agreement digitally
The selected signatory will receive an email with the link “Sign Confidentiality Agreement.”
-
Click the link in the email (it may take a moment for the document to load).
-
Scroll through the entire text or use the navigation button to go to the signature field.
-
Enter your name and title. The date will be filled in automatically.
-
Click the blue “Sign” button.
-
On the next screen, click "Confirm" at the bottom to complete the process.

Step 4: View Documents
Depending on the general contractor’s settings, the following will now occur:
-
Immediate access: After the message "Thank you for signing," you can immediately view and download the documents.
-
Manual release: The general contractor must first verify your signature. You will receive an email as soon as the documents have been made available to you.
Step 5: Download the non-disclosure agreement
Should you require a copy for your records, you can locate and download the signed non-disclosure agreement in your Outbox once the process is fully completed.
Frequently Asked Questions (FAQ)
Question: Why can’t I see the documents yet after I’ve signed? Answer: The general contractor has likely selected “manual release.” You’ll need to wait for a confirmation email before the documents become accessible.
Question: Can I still withdraw a sent request for signature? Answer: If you selected the wrong colleague, you can often choose the option to have someone else sign the agreement in the project’s document screen.
