Redesign logo concept

It all started a couple years ago... When a bus drove past me, with a logo on it... Personally, I found it a very unattractive logo. The months flew by, and often I came across that van or advertising signs.

The logo doesn't even match with what the company does. It's a contracting company/builder company.

So I decided to redesign the logo.

See the three concepts in the attachments! Wich one do you prefer? :)
