AAB logo design

Mr, A logo job: 1) Co name: AAB All About Buildings Conseils en construction (under the name) 2) Activity: Consulting in construction and engineering (all kind of buildings in private and public sector, civic engineering, ect) This logo concerns consulting activity. Once it works well, they will order new onces for related activities (project development and real estate agency ) based on this initial logo, perhaps different color or graphic element. We should keep it in mind. 3) As the logo will be displayed on banners of construction fields, the colors should be pretty eye catchy. 4) Attached you will find some logos he found not perfect but just to give you some ideas. He liked more or less the logo nr 2 & 7. In the logo 1 the idea would be to reflect the engineering part of the activity - like a technical drawing. We can propose one logo that plays with letters in a form of buildings like in the logo 2 and one with buildings as in his exemples. The name should be easily readable - means AAB easy to read too. As the name is already pretty long perhaps playing on letters would be better idea? What do you think? After all I trust you. Any Qs? Many thx.
