Evaluating Commercial Replacement Cost Estimates: Beyond the Numbers Part 1
This is the first in a series of guest posts by Michael Gay. Check out his bio at the end.
A commercial building is insured for $3 million. Then it is destroyed by fire and the projected cost to rebuild is $7 million. How does a replacement cost estimate miss by that much?
Too often, the answer begins with a number generated by valuation software that was treated as a conclusion rather than an estimate. Commercial replacement cost programs can be valuable tools. Still, the apparent precision of their calculations can obscure a fundamental reality: the output is only as dependable as the building information entered, the assumptions selected, and the professional judgment applied.
Construction type, occupancy, square footage, building configuration, construction quality, basements, fire protection systems, local construction costs, code requirements, debris removal, and other variables can materially change an estimated reconstruction cost. An incorrect input, or an important characteristic never considered, can produce an insurance limit that looks defensible on paper but proves dangerously inadequate after a major loss.
This article examines how agents, brokers, underwriters, risk managers, and property owners should evaluate commercial replacement cost estimates rather than accept them at face value. It explores the inputs that matter, the warning signs that should prompt further investigation, the limitations of valuation software, and the circumstances in which a more detailed appraisal or professional valuation is warranted.
The objective is not to predict the eventual cost of reconstruction to the dollar. It is to develop a reasonable and supportable estimate based on accurate information and to recognize when the number on the screen should generate more questions than answers.
A replacement cost estimator is a tool. It is not a substitute for professional judgment.
But That’s What the Estimator Came Up With!
Determining the proper amount of insurance on a commercial building seems straightforward. Enter the building information into a replacement cost estimator, generate a report, and use the resulting figure as the basis for the building limit.
Unfortunately, it is rarely that simple.
In my work as an insurance expert witness, I have been involved in disputes where the adequacy of a commercial building limit became a significant issue after a major property loss. By that point, the discussion is no longer theoretical. The building may be gone, reconstruction estimates may exceed the available insurance, and the insured, agent, and insurer may have very different views about how the limit was established.
For the insured, an inadequate limit can mean a substantial uninsured loss and potentially a coinsurance penalty. For the insurance agent, the same problem can lead to an errors and omissions claim alleging that the agent failed to obtain adequate information, improperly used a replacement cost estimator, failed to recommend sufficient limits, or failed to explain the valuation process adequately.
That is why replacement cost estimating deserves more attention than simply asking, “What number did the computer produce?”
Replacement Cost Is Not Market Value. Etc.
The first distinction is fundamental: replacement cost is not market value.
Market value reflects what a willing buyer might pay for a property. It may incorporate land value, location, rental income, economic conditions, and numerous other considerations that have little to do with reconstruction.
For valuation purposes, a replacement cost estimate generally seeks to approximate the current cost of reconstructing a building using materials and construction of comparable kind and quality. The applicable insurance policy ultimately controls how covered property is valued following a loss.
Likewise, original construction cost is not necessarily current replacement cost. A building constructed 20 years ago for $1.5 million might cost several times that amount to reconstruct today.
Tax assessments, depreciated book values, mortgage balances, and purchase prices therefore should not be casually substituted for a legitimate replacement cost analysis.
This distinction may seem elementary to insurance professionals. In expert witness matters, however, I have learned that what appears elementary before a loss can become surprisingly complicated after one.
