Review Process of Fabrication Drawings and Erection Drawings

In the construction process, basic function of a fabricator is to provide all necessary shop drawings and construction documents to the contractor. These drawings are prepared after thorough review of the design drawings, specifications and bidding documents provided by the structural engineer.

Fabrication drawings commonly include the following:

§ Structural Element Drawings

The drawings for basic structural members, such as web steel joists, must be sealed, signed and dated by the Structural Engineer

§ Erection Drawings

These drawings primarily show the placement of structural members, connections and components to be supplied by the fabricator. When these drawings include design by the Structural Engineer, the drawings shall be sealed, signed and dated by the Structural Engineer.

§ Connection Design or Shop Fabrication Drawings

These drawings provided by the fabricator shall give all information necessary for shop personnel to assemble and fabricate the components. These drawings shall be sealed, signed and dated when incorporating design by the Structural Engineer

§ Construction Engineering Drawings

These drawings provided by the contractor shall cover load analyses, temporary bracing and erection sequence. The drawings shall be sealed, signed and dated by a qualified member.

Drawing submittals should be reviewed for common compliance with the structural Contract

Documents but generally the review does not include issues such as checking dimensions and review of the safety measures. The General Contractor is required to review the submittals before it gets reviewed by the SER.

Fabricator should review the shop drawings and other submittals in conformation with the Contract Documents. When required, the shop drawings should bear the signature and seal of the responsible Structural Engineer. The Structural Engineer whose seal and signature appear on the drawings is responsible for the design of the Structural Members and connections indicated.
