This is an engineering and planning company that does engineering projects in drawing the structures of homes and Comercial buildings.
Bright colors, light blue, light green, yellow, orange, purple, and red
Check logos I like in the below website:
Transparent Links, Watercolor, Potato Chip , Selective Focus , Twined , Sphere Carving, Arc Twists http://www.logolounge.com/article.asp?aid=llPo
The logo design must be artistic and tells the story of the business (Architectural Designing and Engineering Firm) or if you can't come up with something, then a logo with the first letter of the company name done in a way that reflects to the company would be a second way to do the logo.
You can always surprise me with something better that what I am thinking of.
Please check out the latest submissions of my last contest (Destrubutiob Company) as they are the best in my view, and they fit this logo, with changing the look but keeping te concept and spirit)
