DA Form 7307-R: Facility Alteration Cost Estimating Worksheet

DA Form 7307-R: Facility Alteration Cost Estimating Worksheet – DA Form 7307-R: Cost Estimating Worksheet – Facility Alteration (LRA) is a key U.S. Army form used for developing accurate programming cost estimates for facility alteration projects.

This worksheet, issued in April 1994 with the proponent agency being the U.S. Army Corps of Engineers (USACE), supports military construction (MILCON) and operations & maintenance (O&M) projects involving renovations, modifications, or partial demolitions of existing facilities.

What Is DA Form 7307-R Used For?

DA Form 7307-R helps estimators systematically break down costs for altering facilities by accounting for:

  • Removal/demolition of existing building systems.
  • Installation/replacement of new systems.
  • Adjustments for site-specific conditions, such as dust protection, noise/power limitations, limited storage, protection of completed work, and shift work.

It aligns with Unified Facilities Criteria (UFC) 3-730-01, Programming Cost Estimates for Military Construction, which provides detailed guidance on its use for alteration projects.

The form uses a Work Breakdown Structure (WBS) for major building systems, including:

  • 01 – Substructure
  • 02 – Superstructure
  • 03 – Roofing
  • 04 – Exterior Closure
  • 05 – Interior Construction
  • 06 – Interior Finishes
  • 07 – Specialties
  • 08 – Plumbing
  • 09 – H.V.A.C.
  • 10 – Special Mechanical
  • 11 – Electrical
  • 12 – Special Electrical
  • 13 – Equipment
  • 14 – Conveying Systems

Estimators enter percentages of each system to be altered (removed or replaced), labor percentages, and other factors to calculate total costs.

Key Sections of the Form

  • Project Identification: Project number, title, FY, building number, location, facility type, category code, facility size (SF), area to be altered (SF), fund type (MCA/OMA/AFH), estimator details, and basis of estimate.
  • Removal/Demolition Portion: Percent of system altered, percent of labor to remove, total percent removal.
  • Replacement/New Portion: Percent of system replaced, percent of labor to install, system percent of total.
  • Construction Limitation Adjustments: Factors for dust protection, noise/power limits, etc., with percent to add.
  • Summary Fields: RDF, RNF, SAF (Site Adjustment Factor), and overall totals.

UFC 3-730-01 (updated as of 2024) includes a step-by-step example of completing the form and a table comparing costs of removal versus installation.

Who Uses DA Form 7307-R?

  • USACE personnel
  • Army installation engineers
  • Contractors and cost estimators working on Army facility projects
  • Planners developing MILCON or O&M budgets

It is referenced in TM 5-800-4 (the older manual it supports) and current UFC guidance.

Why Accurate Cost Estimating Matters for Facility Alterations?

Facility alterations often involve unique challenges compared to new construction, such as working in occupied spaces, selective demolition, phasing to minimize disruption, and protecting adjacent areas. DA Form 7307-R ensures estimators capture these factors through structured percentages and adjustments, leading to more reliable budgets and reduced risk of cost overruns.

It integrates with broader DoD cost estimating practices, including Guidance Unit Costs (GUC), Area Cost Factors (ACF), size factors, escalation, and site sensitivity adjustments from UFC 3-730-01 and UFC 3-701-01 (DoD Facilities Pricing Guide).
