Accuracy and reliability of Structural design documents play crucial role in the success of building or commercial structure. Find below a checklist of minimum information design documents should contain.
Design team members and drafters should use this checklist to quality-check the completeness of their design documents. Additionally, the team should keep in mind that the structural engineer is fully responsible for the design and sufficiency of all connections.
- Full base plate and anchor bolt requirements including base plate elevations for all columns; diameter, material grade, embedment, size of holes, hole pattern, plate orientation and weld requirements.
- Bracing plates should not collide with anchor bolts.
- Show material grades and sizes of all components, beams, columns and anchor bolts, etc. Completeness, simplicity and repetition leads to savings in cost.
- Cross-check orientation of columns on each plan.
- Show specific column, truss and girder splice location and details.
- Structural steel dimensions should be shown clearly on each plan; checked for precision, especially principal controlling geometry and dimensions.
- The structural drawings should be coordinated with architectural, mechanical and electrical requirements.
- All structural items should be clearly placed and identified on confirmed structural documents. No reference should be provided to external drawings.
- The specifications should be customized as per design requirements of the project. They should be in agreement with all the drawings.
- It is advised that the specifications should include a requirement to take help of pre-qualified fabricators and pre-qualified steel detailers.
- Specify whether all design connections are either based on ASD or LRFD.
- Provide fully developed bracing connections: Show axial loads and whether or not one-third increases in stresses are permissible.
- Show fully developed truss connections: Moments, shears and axial loads depending on function of truss.
- Clearly specify specific safety and erection instructions or local codes in effect.
