Receive free information research on technical topics
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:
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.
How to Submit a New Technical Inquiry
Log in to our member portal using a CAC, ECA, or PIV and then complete the New Technical Inquiry form.
Users without a CAC, ECA, or PIV can email us at contact@hdiac.org with the inquirer's name, email address, organization, active government contract number (if applicable), the technical inquiry, and any additional details.
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.

Notable Inquiries
Notable TIs are findings and/or summaries of responses to the most recent and impactful technical inquiries submitted by HDIAC members under our 4 free hours of information research support.
Use of Ultraviolet Germicidal Irradiation (UVGI) as a COVID-19 Disinfectant
Is there relevant data regarding the efficacy of 254-nm germicidal ultraviolet C (UVC), including dosage required, to effectively disinfect touch surfaces exposed to the novel coronavirus SARS-CoV-2? Does that data contain any applications of the same UVC wavelength to surfaces of aircraft or other transportation interiors?
The Efficacy of Expedient Mask Material and the Effect of Particle Size on Lung Deposition
What biodefense communities have known about the efficacy of expedient masks to protect against infection by aerosolized agents? To what degree are particles of different sizes absorbed in the lung, re-exhaled without absorption, or captured in the mucosal cilia?
Attributing (Negative) Value to Electricity System Outages at Military Installations
What (negative) value is attributed to electricity system outages at military installations? What can we learn from existing studies to help us value upgrading and maintaining our electricity systems? What literature is out there that could inform such decisions?
Example Inquiries
Example TIs are samples of the wide range of technical inquiries submitted by HDIAC members under our 4 free hours of information research support. They are intended to show the breadth of information requests we receive.
