SIGNATURE CAPABILITY

Connections design, stamped by a licensed PE — in any state you build in.

Most detailers hand you a connection and let your EOR figure out if it works. We calculate it ourselves — moment, shear, bracing, and base plate — per AISC 360-22, and put a stamped seal on the package before it leaves our shop.

WHY CALDIM

What your fabricator actually needs from a detailer.

01

Accuracy

RFI rate < 0.8%

Every sheet passes an independent check against contract documents before issue — not a self-check by the modeler.

02

Speed

Avg. 8-day turnaround

Fixed-fee quotes with committed dates. Advance bills issued early so your shop isn't waiting on the full package.

03

Coverage

50-state PE stamping

Licensed structural engineers stamp connection calcs in every US state, so multi-state projects run through one team.

04

Communication

1 dedicated PM per project

A dedicated project manager with 15+ years in Tekla and SDS/2 is assigned to every job — one point of contact from RFQ to RFI close-out, not a shared inbox.

MEET OUR LEADERSHIP

The people who sign off on your steel.

Every package leaves here under a named engineer, not a queue. These are the people accountable for the drawings, the calculations, and the dates we commit to.
