If you’ve been in facilities management for any length of time, you know the Facility Condition Index. It’s the industry’s go-to metric for benchmarking the condition of a building or portfolio – a ratio that compares your deferred renewal needs to what it would cost to replace the facility outright.

The formula is simple: FCI = Total Renewal Needs ÷ Current Replacement Value (CRV)

Here’s what we see consistently: organizations invest a great deal of effort into getting the numerator right – understanding their deferred renewal backlog, commissioning solid FCA work, building out their capital forecasts. And then they use a CRV figure they haven’t really examined in years.

That’s a problem. Because if your CRV is off, your FCI is off. And if your FCI is off, every decision you’re making based on it – which buildings to prioritize, whether to invest or divest, how to tell your story to funders – is built on a shaky foundation.

What CRV Actually Means

Current Replacement Value is the total cost to replace a building with one of similar size, design, and construction using today’s standards. That includes labor, materials, supervision, and contractor overhead. It does not include land, tenant-specific improvements, or furnishings.

It is not the original construction cost. It is not the assessed value of the property. It’s what it would actually cost to rebuild the equivalent building today.

Consistency Matters More Than Precision

Here’s a nuance that surprises people: within your own portfolio, being consistent in how you calculate CRV is actually more important than being perfectly accurate.

If all your CRVs are derived using the same methodology – even if that methodology produces values that are somewhat above or below true market replacement cost – you can still use FCI effectively as an internal benchmark, because every building in your portfolio is “off” by roughly the same amount.

The problem comes when you try to compare your FCIs to another organization that calculates CRV differently. At that point, the numbers aren’t comparable, and any benchmarking exercise is misleading.

How CRV Can Be Calculated

There are several methods, and each has its place depending on your portfolio:

The Simple Square Footage Cost method applies a base cost per square foot by building type – effective for portfolios with similar buildings in a similar geography, like a municipality with seven fire halls built to similar specs.

The Weighted Square Footage method extends this for multi-use buildings, applying different unit costs to each space type.

The Sum of the Parts method aggregates the Element Replacement Values from your FCA data to derive a building’s CRV.

And some organizations use Insurable Value as a proxy – workable, but only if you understand how those values were originally calculated and whether the methodology has been applied consistently over time.

Whichever method you use, cost guides like Marshall & Swift and RS Means are your friends. They provide industry-average baselines, and we always recommend cross-checking your CRV estimates against at least one alternative source.

What to Do About It

If you haven’t revisited your CRV methodology recently – or ever – now is a good time. Ask yourself: how were these values calculated? When were they last updated? Are they consistent across the portfolio? Would they hold up if someone challenged them?

Your FCI is only as reliable as both of its inputs. The good news is that with a sound, consistently applied CRV methodology, the FCI becomes exactly what it was designed to be: a defensible, decision-grade benchmark for managing your portfolio.

Don’t let the forgotten half undermine the work you’ve done on the renewal side.
