Fire, Structure, Site and Compliance
This series publishes working engineering analysis from K&K's data center program. Numbers are labeled [TARGET], [MODELED], [SENSITIVITY] or [FACT]; nothing here is field-measured data, and no article is a sealed engineering document. Each article states its own limits and open items.
- KK-DCL-077Fire Code Matrix Grades 20 Questions Empty; the Summary Says 18Twenty of the twenty-six code and authority questions carry no obtained input in the matrix itself while the chapter's own summary reports eighteen, and the register still separates which of them block work from which are merely unanswered.
- KK-DCL-078A PG25 Release Is Graded an Electrical Fault Before a FireThe fire basis files a glycol release as a release scenario and grades its electrical consequence above a combustion severity that cannot yet be assessed.
- KK-DCL-079Electrical Trip, Valve Close, and Zone Stop Are Separate Interlock EffectsElectrical trip, valve closure and zone shutdown are three separate effects that a cause-and-effect matrix must not conflate.
- KK-DCL-080Nonstructural Anchorage, Not the Frame, Is the Seismic RiskThe governing seismic risk sits in nonstructural component anchorage, which is specified by others and inspected last.
- KK-DCL-081A Uniform Floor-Load Target Does Not Bound Equipment Point LoadsA uniformly distributed floor target does not bound the point loads under equipment feet, and the ratio between them is large.
- KK-DCL-082UL Components Do Not Make a Listed AssemblyComponent listings do not transfer to the assembled enclosure, and the distinction decides who carries the compliance risk.
- KK-DCL-083Two Feeders in One Fire Area Is a Second Common CauseRouting both feeders through one fire compartment adds a second common-cause mechanism on top of the shared substation.
- KK-DCL-084Fuel and Coolant Bunds Cannot Be Counted as Stormwater DetentionSecondary containment volume cannot be counted as stormwater detention, and correcting the double-count tightens the land trial.
