Erection Basic AISC 2025

Introduction

This tutorial outlines the Standard Operating Procedures (SOP) for the erection process as per AISC 2025 guidelines. It covers essential steps from planning and safety to final inspections, providing a comprehensive guide for construction professionals.

Step 1: Prepare Erection Schedule and Safety Plans

• Create a detailed erection schedule that outlines the timeline for each phase of the project.

Develop a site safety plan that includes

• Identification of hazards
• Safety protocols for workers
• Emergency response procedures
• Formulate a lift plan that details the equipment and methods for lifting components safely.

Step 2: Understand Anchor Bolts, Embedded Components, and Safety Signals

• Familiarize yourself with the types of anchor bolts and their installation requirements.
• Ensure that all embedded components (embeds) are correctly placed and secured before erection begins.
• Use green lights or signals to indicate safe conditions for lifting and installation.

Step 3: Create a Comprehensive Load List

Develop a load list that includes

• All materials and components to be lifted
• Weight specifications for each item
• Lift capacity of the equipment being used
• Regularly update the load list to reflect any changes in materials or weights.

Step 4: Install Leveling Nuts and Columns

• Begin with the installation of leveling nuts before erecting columns.

Follow these steps for column installation

1. Set the first column in position.
2. Use a plumb bob or level to ensure the column is vertical.
3. Secure the column temporarily before final adjustments.

Step 5: Box and Fill Procedures

• Construct boxes and fill them with concrete or other materials as specified in the design.
• Ensure that the fill is compacted adequately to support the structural loads.

Step 6: Align and Square the Structure

• Use measuring tools to check that all components are aligned correctly.
• Check for squareness by measuring diagonals across the structure. Adjust components as necessary.

Step 7: Detailing and Additional Steel Installation

• Install any additional steel components required for detailing.
• Ensure all connections are made according to engineering specifications.

Step 8: Final Shake Out, Deck Installation, and Welding

• Perform a shake-out to check for loose connections or issues in the structure.
• Install decking as per the design requirements, ensuring proper support and alignment.
• Complete the final welding (weld-out) of structural components, following safety protocols.

Conclusion

This guide provides a structured approach to the erection process in accordance with AISC 2025 standards. Key steps include thorough planning, safety protocols, and precise execution of installation tasks. For further improvement, consider conducting regular training sessions for crew members to ensure compliance with safety and procedural standards.
