Structural Steel Shop Drawings

All of our shop drawings are extensively checked to ensure that they are error free.

This includes interrogating the 3D model prior to producing shop drawings to ensure:

1. There are no steel clashes and

2. There are no bolt access problems


Once drawings are produced, each one is individually checked and edited to ensure that it is clear and concise.

This includes:

1. Re-dimensioning drawings as required to improve legibility.

2. Adding additional sections or blow-ups as required to provide extra detail.

3. Adding revision letters, descriptions, and clouding to all revised members and GA’s.

4. Adding a description of each member to the title block.

5. Adding a member prefix to all steelwork members to aid in identification and erection.

6. Adding a material finish to each member and assembly drawing.
