An incorrect bolt hole, connection or material specification becomes much harder to resolve after steel has been cut or drilled. A pre-fabrication review therefore asks a practical question: Is the drawing package complete, coordinated and approved for production?

ZSJH engineers review the architectural and structural drawings, spans, loads, applicable standards and material requirements. Calculations and a 3D model can help check members, connections and installation access. The model supports the review; it does not replace engineering checks or client approval.

Review and release workflow:

Open questions should remain on an issue list until written answers are received and checked. ZSJH releases project-specific fabrication against the final approved revision and links member identification to production and inspection records. Finished components still need physical checks before delivery and erection, including dimensions, visible damage and weld condition. Drawing review does not replace that later inspection.

FAQ 
Can we submit incomplete drawings?
Yes. Send ZSJH the available drawings, project location, building dimensions, span, loads, materials and required services. The technical team can identify missing information and discuss the design, calculation or detailing scope.
