In this episode, we talk to Jim Amundson, P.E., SE, Vice President, and Principal at Coffman Engineers, about important aspects you need to know about when selecting the appropriate structural framing system for a building.

Here Are Some of the Questions We Ask Jim:
- What is the thought process in selecting a structural framing system?
- What information is needed from an owner, architect, and other consultants to select a structural framing system?
- How do you validate the framing decision?
- What are some of the pros/cons of a steel-framed building versus a concrete-framed building?
- What are some current challenges in the building industry, and how are they impacting the framing decision process?
Here Are Some of the Key Points Discussed About Choosing the Right Structural Framing System:
- The thought process begins as soon as the project is received. You must decide on the correct structural framing system for the building type and which building code provisions pertain to it. You must understand both the owner and the architect’s design intent. The materials for the structural framing system must be determined according to the building codes and the design intent.
- Get input from the contractor, architect, and owner because there are several pros and cons to using either steel or concrete for the structural framing system. Concrete can help with starting construction immediately, whereas the steel is a long-lead item of six months or longer. The overall structural depth of a concrete building can be considerably less than a steel building. A steel structural framing system has less mass than a concrete building, which will have less impact on your foundation. A steel structural framing system has a lot more flexibility in making changes to the building at a later stage. Concrete has its inherited fireproofing whereas steel needs to be fireproofed. The cost of a steel structural framing system and a concrete structural framing system is not very different.
- The price of concrete has not moved much during the pandemic, but the structural steel price has risen by about 25% and is starting to impact the cost of projects. Steel is also a lot more difficult to procure because of the supply chain disruption. Getting your steel mail order placed in a timely manner is critical so that the project’s schedule is not disrupted.
- Using the design-build method is good because the contractor is part of the team from the early stages of a project. They can help with validating the construction decisions, offer input, help to change decisions based on what they know, and have a good knowledge of the availability of materials. The design-build method is a great way to have all parts of the team working together toward a common goal.
- Young engineers should try to get a variety of experiences early in their careers. It will help widen your knowledge base, which you can use later in your career. Getting involved with a professional organization is a prime way to network and give back to your profession. Start building your network as early as you can because it is a valuable tool that you can use to get input from other engineers, and it can help you if you want to make a move in your career.
