DA Form 5605-5-R PDF: Life Cycle Cost Analysis – If you work on U.S. Army military construction (MILCON) projects, facility upgrades, or energy conservation initiatives as a military engineer, contractor, or Department of Defense (DoD) professional, you’ve likely encountered DA Form 5605-5-R. This official U.S. Army form delivers a streamlined tool for Life Cycle Cost Analysis (LCCA) using the Present Worth: One-Step Approach.
In this SEO-optimized guide tailored for U.S. audiences, you’ll learn exactly what DA Form 5605-5-R is, why it remains relevant for Army and USACE projects, how to use it step-by-step, its benefits over traditional methods, and where to download the latest fillable PDF.

What Is DA Form 5605-5-R?
DA Form 5605-5-R (December 1986) is titled “LIFE CYCLE COST ANALYSIS – PRESENT WORTH: ONE-STEP APPROACH (LRA)”. The U.S. Army Corps of Engineers (USACE) serves as the proponent agency, and the form remains ACTIVE today.
It supports TM 5-802-1 (Economic Analysis for Military Construction Design) by letting users quickly calculate the net present worth (PW) of project alternatives. Instead of performing year-by-year escalation and discounting calculations (the “conventional approach” covered in related form DA Form 5605-4-R), the one-step method uses pre-computed adjustment factor tables that combine discount rates and differential escalation rates in a single multiplier.
Key sections on the form include:
- Project/Alternative identification and criteria reference
- Analysis Base Date (ABD) and Analysis End Date (AED)
- Annual discount rate and differential escalation rate (%)
- Cost categories: Initial Costs, Energy/Fuel Costs, Maintenance & Repair (M&R), and Other
- Columns for: Cost on ABD, One-Step Adjustment Factor (from Table 1, 2, or 3), and Present Worth on ABD
- Net Present Worth summary
Note on tables: Use One-Step Table 2 for M&R costs (escalation e = 0) and Table 3 for energy/fuel costs (with prescribed e value).
Why Life Cycle Cost Analysis Matters for U.S. Army and DoD Projects?
Federal law and DoD policy require LCCA for MILCON, energy projects, and major facility investments. Executive Orders, the Energy Independence and Security Act, and Unified Facilities Criteria (UFC) emphasize evaluating total ownership costs—not just first costs—to deliver the most cost-effective, sustainable solutions over decades.
USACE Engineering Regulation ER 1110-1-8173 (Energy Modeling and Life Cycle Cost Analysis), issued in 2017 and still guiding current practice, mandates documented LCCA for qualifying building projects. It pairs with energy modeling to prioritize high-return energy conservation measures.
The Present Worth method (required for federal projects per 10 CFR 436 and NIST guidelines) converts all future costs to today’s dollars using the Analysis Base Date, enabling fair “apples-to-apples” comparisons between design alternatives.
One-Step Present Worth Approach vs. Conventional Method
| Feature | One-Step Approach (DA 5605-5-R) | Conventional Approach (DA 5605-4-R) |
|---|---|---|
| Calculation Style | Single adjustment factor per cost category | Year-by-year escalation then discounting |
| Speed | Fast—ideal for early design screening | More detailed but time-consuming |
| Best For | Uniform or escalating annual costs (M&R, energy) | One-time or non-uniform cash flows |
| Tables Used | Pre-built One-Step Tables 1–3 | Separate escalation + discount factors |
The one-step method saves significant time while remaining fully compliant with TM 5-802-1 methodology.
Step-by-Step: How to Fill Out DA Form 5605-5-R?
- Enter Project Details — Alternative number, title, and criteria reference.
- Define Analysis Parameters — Set ABD (usually midpoint of construction or current date), AED (typically 20–40 years for buildings), discount rate (per current OMB Circular A-94 or USACE guidance), and differential escalation rates for energy/fuel.
- List Costs in Base-Year Dollars — Convert all costs to ABD dollars.
- Apply One-Step Adjustment Factors:
- Initial/one-time costs → often use a simple discount factor.
- M&R costs → Table 2 (e = 0).
- Energy/Fuel costs → Table 3 (with specific e value).
- Calculate Present Worth — Multiply Cost on ABD by the Adjustment Factor for each line item.
- Sum to Net Present Worth — Compare alternatives; the lowest PW is usually preferred.
- Document Assumptions — Include narrative on the summary form (DA 5605-2-R) for the project design analysis package.
Pro Tip: For modern projects, cross-check results with NIST Building Life-Cycle Cost (BLCC) software, which automates these calculations using current OMB discount rates and energy price forecasts.
Benefits of Using DA Form 5605-5-R
- Faster Decision-Making — Screen multiple design alternatives during 35% or 65% design reviews.
- Cost Savings — Identifies options that minimize 30–40 year ownership costs (often dominated by energy and maintenance).
- Compliance — Meets USACE, DoD, and federal LCCA requirements for MILCON and ECIP projects.
- Transparency — Clear, auditable calculations using official tables.
- Training Tool — Excellent for understanding LCCA fundamentals before moving to software.
U.S. Army engineers and contractors use this form (or its principles) on bases nationwide to justify investments in energy-efficient HVAC, lighting, building envelopes, and renewables.
Modern Context and Related Resources (2026 Update)
While the 1986 form remains officially active and available, current USACE practice often pairs manual forms with:
- NIST BLCC software (recommended for final documentation)
- ER 1110-1-8173 requirements for energy modeling + LCCA
- UFC 1-200-02 High Performance and Sustainable Buildings
Still, the one-step approach on DA Form 5605-5-R provides the foundational manual method taught in USACE economic analysis training.
