Structural Engineer vs Architect - Design Meeting

A structural engineer is a part of the design team for all my residential work in the studio. In this video you'll join me for the kick-off meeting with my structural engineer as we begin developing the structural design for the Outpost project. You’ll see how we choose a foundation strategy, work through framing + detail ideas, and understand how lateral loads are transferred and how they affect the materials we choose to build with. The professional tug-of-war between engineer and architect isn't adversarial, rather it's collaborative and makes for a better, more efficient project.

The most interesting part of our dialogue begins around minute eighteen where I ask Albert to comment on one of the most common objections I hear from contractors in the field: "This structure is way over-engineered." His answer illuminates how a structural engineer can complement the architectural design process in ways you may not have anticipated. Not only do engineers help us to efficiently size structural members and optimize the design, but their practical building knowledge and field experience can prove invaluable.

Because an engineer’s work is smaller in scope, (their fee is typically about 10% of an architectural fee), they must secure 10X the number of commissions to make a comparable income. This naturally exposes them to many more projects (in theory 10X), ideas, and failures than an architect would typically see. And, it’s those failures that are the most instructive. This symbiotic relationship between architect and engineer has benefitted my practice and my clients in ways that are difficult to calculate but that surely far exceed the engineering fees invested.

Structural engineering is more than sizing beams, designing connections and specifying concrete mixes, it’s an allied discipline which helps to make our jobs as architects easier and to deliver a home that meets (and often exceeds) our client’s expectations.

Although this footage is but a small sampling of our conversation, you can appreciate the give and take that a typical design collaboration entails. As professionals, we rely on the expertise of many consultants to realize our architectural goals.

This is a long video, here’s a few timestamps to guide you:

0:30 ** General Site + Foundation Considerations
4:05 ** Architectural Goals
5:02 ** Roof Design + Framing
6:36 ** Eave Detail
8:55 ** Possible vs. Practical
10:00 ** Designing for Lateral Loads
13:24 **Transferring the loads: bracing (wood vs. steel)
18:12 ** “This feels over-engineered” – The most common complaint I hear from contractors in the field (DON’T MISS THIS SECTION)
22:09 ** Value of engineers from an Architect’s perspective
23:43 ** 10X Projects, 10X Failures, 10X Knowledge (a convincing case for collaborating with engineers)
25:10 ** Engineer’s steel manual vs. Architect’s steel manual

    this engineer is very well spoken it’s mind blowing how he keeps someone engaged and interested a conversation about construction
  • At my old firm, our structural engineer was 82 and still sharp as a tack. He worked on the original WTC and countless other impressive projects. Those meetings with him were by far the best because you're the one that now has to sit, listen, and learn. He would calmly look over the architecturals and bust out his calculator and start pumping out calculation after calculation, sizing beams and joists and always making sure that his structurals wouldn't interfere with our designs. RIP Franz

    fun fact: you didn't search for this but you actually stayed and watch
  • @civilmix
    (Good Engineer + Good Architect) = Perfect Design 😍
  • @RobertoLicardie
    This video makes me realize that I need to get better at speaking cohesively and professionally while keeping cool. Oof.
  • @adilmuhammad765
    The architect is the dreamer and the engineer is the genie making his wishes come true
  • @LuiZ-jy1pi
    ahhh I see... so this is what engineers do... (I have an engineer degree, and apparently, I learned nothing.)
  • @Tamshea88
    It's nice to see a video talking more about the structural aspects of buildings for a change. It would be nice to see some more of your videos on your thought process of structural designs.

    Construction is an interesting industry. It's easy to see an architect as the master designer and be-all and say-all of a project. But there is a definite pecking order which everyone getting into the industry should understand... An architect designs a building to look nice, they make the pretty pictures and decide where the doors go and essentially sell the project to a client, they will have final say on anything as they are essentially taking responsibility for the design of a project. The main contractor (general contractor in the US) is the company/person paid by the client to build the project which has been envisioned by the architect. They are ultimately the top dog, they are the ones spending the clients budget to make the project a reality, if they can deliver under budget then they make more money, if costs spiral then they lose money or have to beg the client for more. The actual extent of works that a main contractor will carry out themselves depends on their abilities. The engineer liases with both the architect and the main contractor as well as relevant sub contractors to figure out what is actually required to make the thing not fall down and kill someone or that the building doesn't fail in slightly less important ways. They have to do this for the lowest possible costs otherwise the main contractor will not be happy. If they massively over engineer things, the main contractor will lose money, if they under engineer things, the building and lives may be at risk. Subcontractors work for the main contractor and perform smaller elements of the main project, their works are typically much more specialised such as glazed and cladded facades, elevators, modular building elements, even down to steelworks, concrete works, balconies, canopies, rooflights, mechanical and electrical elements, security consultants, environmental impact contractors as well as about 30 other trades and specialists. I work as a designer for a facade contractor, we design a solution to try to meet the specification of both the architect and engineer while maintaining the requirements (in cost and performance) set out by the main contractor. Finally you have the boots on the ground, the people actually constructing the building. They have to work at a level of detail which is almost impossible to appreciate in paper right up until the highest detail of 3d models. They are the ones who realise that the opening cupboard door is clashing on the side of an oven. Or that a cladding panel is 3mm too short resulting in an excessive gap around an opening or that an EPDM seal is not sufficient in the corner of a curtain walking screen. Construction is only possible because everyone works to their strengths.

    21:21 "If it's been built a million times, you don't need a structural engineer. But once there's something unique about the design, that's when professionals get brought in."
  • as a college junior in civil engineering this is such a cool conversation to watch
  • I have never seen a duo of educated men talk so respectfully and collaborate this well with one another. There was no power tripping or ego, just communication and solutions. Incredible!
  • @Thomaesthetics
    One of the greatest videos I’ve seen on YouTube in a while
  • @dmontenegro
    As an aspiring structural engineer, I have to say this is one of my favorite videos of @30X40 Design Workshop! This engineer is so well spoken and the visuals help explain the details discussed in this meeting.
  • @tauser10
    I’m in my third year of architecture school and I have always wondered how a conversation and negotiation between a structural engineer and an architect would be played out. This is very helpful. If you could, im sure many future architects would appreciate future conversations between you two again. Just thank you!
  • @Khalil-zn8nb
    I first watched this video when I was still in high school, confused on what to study in college, whether structural engineering or architecture. I did not understand anything way back then. Now that I am a first year college studying structural engineering, I'm happy to understand their conversation even just a little. 5 years from now, hopefully when I graduate, I'll comeback here and try to understand this completely.

    Architect: The Artists that dreams up ideas. Engineer: The person who has figure out how make them a reality.
  • @aarond9563
    THIS IS FASCINATING! You guys speak so patiently and thoroughly. I can imagine this meeting was hours long, if not, at least an hour. There is no interrupting or impatience at all it seems. I can't WAIT to see the final product.
