Use DA Form 5605-1-R when you need to life cycle cost analysis savings-to-investment ratio (sir) & discounted payback calculation (lra). Full title: LIFE CYCLE COST ANALYSIS SAVINGS-TO-INVESTMENT RATIO (SIR) & DISCOUNTED PAYBACK CALCULATION (LRA). Everything you need is on this page — the file, the entry rules, the routing. Edition 12/01/1986, status ACTIVE, 1 page(s), roughly unknown fields. Note the supersession: a later edition exists, and this one applies only to records already completed on it.
Authority sits in two places. USACE owns the form, not stated says when it is raised and where it goes. Routine cases need neither read in full — the page itself carries the sequence. The entries are completed by their subject or by unit administrative staff working from what that person supplies.
Pick by how you will enter data: PDF on offer. Typing means fillable pdf, where the boxes accept keystrokes and hold them on save. Handwriting means printable pdf, a flat page image sent straight to a printer. Neither version changes what appears on the page.
A standalone reader is the safe choice for fillable work. Browser viewers vary in whether entered data survives the session, and there is no warning when it does not; a one-field save test settles it in seconds.
Free, unregistered, unmodified. What arrives is what the publisher released.
The heading entries carry more weight than the body. Name spelled as in official records, identification number, organisation, date prepared. Retrieval runs on those values, so a transposed digit or a casual spelling costs someone a file search. Fill them before anything else.
Tab through the fields rather than clicking. The tab order was fixed when the form was built and generally follows the page, which catches boxes a mouse skips past. Check boxes and option buttons take a click, and an exclusive group clears the previous selection when you make a new one. Single-line fields do not wrap — text past the field width prints truncated while still showing in full on screen, which is why the loss is discovered after printing. Overflow goes to remarks or a continuation sheet. A field that does not apply gets the mark meaning none; blank space reads as an omission.
Sign last. An unsigned form is a draft whatever else is on it, and additional signatures — reviewer, approver, witness — follow printed block order with each signer dating the day they sign, not the day of preparation. Four faults account for most returns: a blank mandatory field, transposed digits in an identification number, day and month reversed in a date, and leftover entries in a working copy reused instead of a fresh blank. Read the form once from the top before releasing it.
Privacy Act statement first, personal entries second. The notice covers who is authorised to collect, why, who else routinely sees it, and whether you must answer. After completion the file carries personal data and is stored and sent under the corresponding safeguards.
Send it where the directive says: the office it names, the unit administrative channel, or the individual's file. Take your copy before submission. How long the record is held comes from the schedule for the series, not from the office holding it.
Companion documents come from the same series and number scheme. Within the DA series, a shared proponent or a shared directive usually means shared use, and a form cited on the face of another accompanies it. Gather the whole package first — continuation sheets, cover sheets, transmittals.
A stored file goes stale silently. The proponent revises, a new edition date is published, and your copy says nothing about it — so compare the printed date against the edition in force before typing into it again. Completed submissions on an earlier edition are not reopened.
What is distributed here are reproductions of published Department of the Army documents. Independent site, no official standing, no forms of its own. Nothing on the page constitutes legal advice, and acceptance by any office is outside what can be stated. Put questions about entries, requirements or eligibility to USACE or your servicing administrative office.
