Published-basis planning tool
SCIF construction cost estimator
See separate published whole-facility construction benchmarks. This is not a National Shielding quote and does not set accreditation scope.
How to read the result
Below 200 square feet uses a Texas public planning benchmark of $1,500–$1,800 per square foot. At 200 square feet and above, it uses a published general range of $350–$1,000 per square foot. These are distinct sources, not a continuous cost curve, so crossing 200 square feet can lower the displayed range.
Worked example
At 199 square feet, the small-room benchmark produces $298,500–$358,200. At 200 square feet, the general benchmark produces $70,000–$200,000. The change reflects distinct published sources, not a price reduction or National Shielding quote.
Limitations
The CTTA, Accrediting Official, threat assessment, site conditions, perimeter, penetrations, security systems, schedule, labor, procurement and verification control actual scope and cost. Region, storage, TEMPEST and sound needs have no unsupported numeric multiplier here.
