GOVERNANCE & SCOPE BOUNDARIES

Trade Operating Boundaries

Every engagement has unambiguous jurisdictional guardrails. Select a trade vertical below to inspect the exact boundaries between what HX produces and what your licensed team retains.

Structural Steel Detailing

Remote detailing production for steel fabricators.

We work inside your standards and from your information. Engineering stays with the responsible design professional; your team keeps checking, project decisions, and release.

✓
What we do
Production drawings
Shop, fabrication, and erection drawings produced to your standards and returned for your checking.
The repetitive volume
Repetitive assemblies, misc steel, stairs and rails, platforms, and secondary framing.
Revision cycles
Redline turnaround and revision production — where most detailing departments actually drown.
Model production
Buildout in the platform your shop already runs, using your templates, naming, and piece-mark practice.
We ask instead of assume
Missing dimensions, conflicts, and unclear criteria come back to you as questions. We never guess to keep moving.
We check before we deliver
We run the agreed production checks before delivery. Your technical checking and release review stay final.
Scale by package
Capacity added for a package and stopped when it ends. No permanent seat to keep filled.
✕
What we do not do
No connection design
We do not set structural criteria, design connections, or perform delegated engineering.
No sealing or release
We do not sign, stamp, certify, issue for fabrication, or submit anything as the responsible party.
No shop or field decisions
Means, methods, sequencing, weld procedures, and procurement stay with you.
No field verification or certification
We do not measure, survey, or inspect. We can incorporate field information your team provides, but we do not verify or certify it.
No outside communication without your approval
We do not contact your customer, the GC, the EOR, the erector, or any other project party unless you authorize the specific role.
No permanent headcount
This is managed production capacity, not employee placement. No recruiting process, no permanent seat, no added payroll position.
Schedules depend on complete inputs
Late, incomplete, conflicting, or inaccurate information affects production and schedule. We identify it early so your team can resolve it.
