JURISDICTIONAL INTEGRITY

What Stays With You, Always

We never blur the line between volume production and professional responsibility. The core judgment functions stay squarely inside your firm:

  • Architectural blueprints and floor plans rolled and laid out on a surface.

    1. Design Intent & Criteria

    Design criteria and design intent stay with your team.

  • Fire sprinkler system with red pipes, gauges, and valves in a building's utility area.

    2. Connection & RFI Decisions

    Clash resolution, RFIs, and connection approval stay with your leads.

  • Close-up of a person's hands holding a metal sheet near an industrial machine with multiple metal components.

    3. Quality Checking & Sealing

    Your licensed professional signs, stamps, and authorizes submission.

  • Industrial setting with electrical control boxes and red containers on a metal shelving unit.

    4. Client Relationship & Release

    We don't contact your GC, owner, or architect. You own the release.

GOVERNANCE & ANSWERS

Answers To The Questions You Are Already Asking

A mechanical room with pipes, pumps, tanks, and a control panel. Contains three black pumps, a blue tank, various pipes, valves, and electrical wiring.

  • No. You are doing the opposite: protecting your department. Right now, your most experienced people are spending 70% of their day setting up title blocks, moving cut-sheet dimensions, and redrawing secondary framing. HX takes the repetitive drafting volume off their desks so they can focus on connection review, field coordination, and change-order defense.

  • HX holds the contract and owns the quality layer. You have one U.S.-based point of contact who coordinates scope, questions, milestones, and delivery. Your detailing manager does not manage individual production drafters across time zones.

  • We log them immediately on a formatted Question Log and send them to your lead checker during your normal business hours. We never guess, interpolate, or bury discrepancies to keep drawing.

  • None. There is no permanent seat, no annual retainer lock, and no payroll recruiting fee. Capacity is engaged by the package and stopped when the package ends.
