The industry is not really "construction." It is design; structural design, or consulting; structural engineering consulting. Both of which are directly related to construction.
As far as a slogan/tagline, I do not have a strong opinion about whether this is incorporated or not, but if it would add something to the logo design, it would be "Engineering Services. Sensible Solutions." Obviously, I would want the tagline on the business card.
Regardless, I want the logo to be functional WITH OR WITHOUT the tagline, so if the tagline is included as part of the logo, a second version should be provided without the tagline.
Also, I would like the logo to be appropriate for embroidering, and I would like it to be usable on both light and dark materials, this may require a "negative" logo or background. I do not really want a permanent background, but could possibly use one when needed against a similar color fabric/media.
The business name is STRUCTURAL DESIGN RESOURCE, but in some ways, I like the idea of having "SDR" incorporated into the logo. The full name should still be written out as part of the logo though.
