What should be done first in the installation process of structural steel members?

The first step in the installation process of structural steel members should be to verify member location against shop drawings. This is crucial as it ensures that all components are appropriately positioned as per the design specifications. By checking the shop drawings, installers can confirm the accuracy of measurements and alignment, preventing costly mistakes during the installation process.

Conducting a pre-installation meeting, while important for project coordination and communication, serves as a preparatory step but doesn't directly involve the physical placement or verification of steel members. Securing the base plates is a critical action, but it follows the confirmation of accurate placement, as the base plates are typically secured only after verifying that the members are in the correct locations. A load test, essential for ensuring structural integrity and safety, is conducted after installation and thus is not relevant to the initial steps of the installation process. Therefore, verifying member location against shop drawings must be prioritized to set the stage for a successful construction phase.
