Fabrication/Supply of Structural Steel
Summary of the Process
Thank you for choosing Northern Services for your steel construction needs. Steel Fabrication is a production; there are many moving parts that make up your finished product. The following is intended to educate our customers about the production process, so we can better work together to complete your job on time and within budget.
Our process is based on the American Institute of Steel Construction (AISC) Code of Standard Practice for Steel Buildings and Bridges. You will see several references within this document to specific sections, and for full publication please see: https://www.aisc.org/publications/steel-construction-manual-resources/

“Approved approval documents shall be individually annotated by the owner’s designated representatives for design and construction as either approved or approved subject to corrections notes. When so required, the fabricator shall subsequently make the corrections noted and furnish corrected fabrication and erection documents to the owner’s designated representatives for design and construction.”
Per AISC 4.1
“When the owner issues design documents and specification that are released for construction, the fabricator and the erector rely on the fact that these are the owner’s requirements for the project. This release is required by the fabricator prior to the ordering of material and the preparation and completion of the approval documents.”
