Steel Erection 101: Part 4 - Load Lists and Yarding

Introduction

This tutorial focuses on the critical aspects of load lists and yarding steel in the steel erection process. Understanding these concepts is essential for ensuring safety and efficiency on construction sites. This guide will break down the steps needed to create an effective load list and yarding strategy, which are vital for coordinating steel delivery and placement.

Step 1: Understand the Load List

Creating a load list is foundational for managing steel erection. Follow these steps to develop an effective load list:

• Identify Components:

  • List all steel components required for the project, including beams, columns, and plates.

• Specify Quantities:

  • Ensure each item has the correct quantity needed for the job.

• Include Weights:

  • Document the weight of each component to aid in planning lifts and ensuring crane capacity is not exceeded.

• Organize by Delivery Sequence:

  • Arrange the items in the order they will be delivered to simplify unloading and yarding.

Step 2: Develop a Yarding Plan

Yarding involves the organization and storage of steel components on site. A well-structured yarding plan facilitates efficient access and safety. Consider the following:

• Designate a Yarding Area:

  • Select a location that allows for easy access to the construction site and minimizes the distance for lifting.

• Create Layout for Components:

  • Arrange components based on the load list to ensure that items needed first are easily accessible.

• Implement Safety Measures:

  • Ensure the yarding area is free of hazards and clearly marked to avoid accidents during steel handling.

• Use Markers:

  • Label each steel component clearly to prevent confusion during the erection process.

Step 3: Coordinate Delivery and Unloading

Effective communication and coordination during delivery and unloading are crucial. Follow these steps:

• Schedule Deliveries:

  • Set a timeline for when each load should arrive based on the project schedule.

• Communicate with Delivery Teams:

  • Ensure that all team members understand the delivery schedule and yarding plan.

• Plan for Unloading:

  • Assign team members to manage the unloading process, ensuring they are aware of the positioning of components.

Step 4: Inspect and Verify Components

Before the components are erected, conducting a thorough inspection is necessary.

• Check for Damage:

  • Inspect each piece for any visible damage that may affect its integrity.

• Verify Specifications:

  • Confirm that all components match the specifications outlined in the load list.

• Document Findings:

  • Keep records of any discrepancies or damage for future reference and accountability.

Conclusion

Understanding and effectively implementing load lists and yarding strategies are essential for successful steel erection. By following these steps, you can enhance efficiency, ensure safety, and improve coordination on your construction site. As you progress, consider exploring more advanced topics in steel erection, such as the sequence of column placement and plumbing your structure, to further refine your skills.
