How Drawing Review Caught Clashes on Three California Schools

1,200+ Sheets Across Three Schools Heading to DSA Review

A mid-size architecture firm was drawing three new schools for a Southern California district under one bond: elementary, middle, and high school. The combined set was more than 1,200 sheets. Each building was at a different stage, and a different team lead owned each set.

Senior architects still redlined prints. That worked for one building. It did not catch structural and MEP clashes, or the same detail drawn three different ways, when each team lead owned a building.

DSA review was coming up. An internal pass of all three buildings usually took four to six weeks.

Helonic Found 67 Versions of the Same Detail Across Three Schools

The firm uploaded all three sets at once. Each building was checked on its own, and the consultant sheets were compared with the architectural plans.

Helonic listed 841 issues. The expensive ones were clashes between the architectural sheets and the structural and MEP consultants, dimension mismatches, and details that did not agree from building to building.

Code notes were in the list. They were not what would have cost the job. The clashes and the mismatched details were.

841 Coordination Items Sorted by Building

QA/QC sorted the list by severity and building. Senior staff spent their time on the 841 locations that needed a correction, instead of a full print review of every sheet.

The gym structure and the cafeteria mechanical mains did not fit the architectural plans. Catching that before issue avoided a redraw measured in weeks, not a note on a code sheet.

The three teams had also drawn the same slab edge and the same duct penetration 67 different ways. They picked one detail before the sets went out.

The cafeteria mains are the most common kind of conflict Helonic finds. Across 1,000+ drawing packages Helonic has reviewed, architectural and mechanical sheets accounted for about 29% of coordination conflicts, the largest single discipline pair. See constructability review ROI data.

DSA Review and the Field Act on Three California Public Schools

California public K-12 schools are reviewed by the Division of the State Architect (DSA), not the local building department. The Field Act, passed after the 1933 Long Beach earthquake, requires that review for structural safety. DSA also reviews fire and life safety and accessibility.

DSA reviews against the California Building Code, Title 24, including its school-specific structural provisions. It also oversees construction through project inspectors, so a change after approval goes back to DSA as a construction change document.

That is why consultant clashes cost more on a public school than on a private building. A gym structure or a cafeteria main that does not fit the architectural plans cannot be settled on site with a field sketch. It needs a revision that DSA approves.

Bond-funded districts also work to opening dates tied to the school year. A redraw measured in weeks can push a building past the start of classes.

“Running three school buildings through QA/QC simultaneously was overwhelming our senior staff. Helonic found 841 issues and organized them in a way that let us fix patterns across all three buildings at once instead of checking each one from scratch.”
