You have arrived looking for DD Form 1220. Before you download, confirm this is the right document: Concrete Mixture Design Data. Full title: DD Form 1220, Concrete Mixture Design Data, August 1957.
Your second step is the edition, not stated, listed as not stated. Your third is scope. Because the number carries a DD prefix, you use the same blank as every other military department and defense agency; no service-specific version exists for you to hunt down.
Then settle the schedule. You are working under not stated, with not stated responsible for the document, and your organization layers its own deadlines on that. Ask before you assume a date.
Before you download, pick your approach — editable file or printed page. What follows covers the formats first, then the entries, then what you do afterward.
Now fill it in. Work from the top of the page downward, and do not jump ahead — the identifying block comes first, the substance of your entry second, the certification last. Later boxes often depend on what you put at the top.
Before your first entry, look at the corner of the page and compare the printed date with not stated. If they do not match, stop and download again. Old copies circulate in shared drives for years, and a DD form is revised centrally for every service at once, so a superseded blank may not carry the fields your reviewer expects.
For questions about a specific entry, check the form's own instructions, and if that does not settle it, open not stated. The directive controls where they differ.
Download the form
First, look at what you can download. The set covers PDF, the form runs 1 pages, and you will complete roughly 107 fields.
Take the pdf if you are unsure. Then check which kind you have: if the boxes highlight when you click them, you have a fillable pdf and can type straight into it, and your entries save with the file. If nothing highlights, you have a printable pdf — send it to a printer and use black ink.
Go with the typed route whenever the choice is yours. Consider what happens after you submit: the copy gets scanned, forwarded and filed, and each pass costs handwriting some legibility. Block letters help if you are stuck with a pen.
Whichever you pick, you pay nothing — every format here is a free download. One last tip: open your pdf in a desktop reader rather than in a browser tab, because browser viewers sometimes drop the interactive fields you need.

Now that it is complete, send it where not stated or your local procedure says it goes. Before you do, make yourself a copy — scan it or save the file elsewhere. It costs you nothing and saves you the whole exercise if the original goes missing.
Should you need a related form, look it up by its number. The DD sequence is Department-wide, which makes your search simple: no service qualifier, no branch-specific variant to track down.
Here is where people go wrong. They see a number in an instruction and download whichever form matches it. But DA and DD are separate systems — Army-specific in one case, Department-wide under not stated in the other — so check which series you were sent to before you take the file.
Plan to repeat this step whenever the form comes up again. Revisions follow directive changes, changes in what data is collected, and updates to notice language. Since nobody notifies you, check not stated at download and you have covered it.
One thing this page does not do: tell you whether your submission will be accepted. We publish the document and explain how to complete it, and that is where our role ends. Nothing here is legal advice. Take questions about eligibility, applicability or procedure to not stated, to your servicing personnel office, or to the office named in not stated.
