Technical Inquiries (TIs)

The core function of HDIAC is to answer technical questions using our in-house technical personnel, vast DoD information resources, and our extensive network of subject matter experts (SMEs). HDIAC has technical staff available to conduct technical research in order to give you a head start on your analysis or study in any of our technical focus areas. We offer a free 4-hour TI research service or, for slightly larger research efforts, we offer an extended technical inquiry (ETI) service.

Technical Inquiry Features

Our TIs include the following to help you with your research:

magnifying glass
Literature Searches

Document Requests

Dissemination of technical reports to authorized users

Free Technical Inquiry Services

HDIAC’s free TI service offers 4 hours of free research per inquiry on any topic within our technical focus areas. Typical TI efforts may include answering technical questions, literature searches, document requests, or referrals to SMEs. Completed responses are compiled and delivered to the inquirer in less than 10 business days. Registered users can submit TIs online through the provided form or by phone.

Extended Technical Inquiry (ETI) Services

ETIs are externally funded research efforts that go slightly beyond 4 research hours. ETIs require between 5 and 160 technical hours of research, with a $50K maximum ceiling and period of performance up to 2 months.
