Their target market are mostly Land Developers, Councils and Government services. They mostly deal with males in a management role.
They don't deal with the general public, and usually are talking about quite pricey jobs so the quality of the imagry needs to be classy.
There are currently no corporate colours for the business, and no specific wishes for any new corporate colours. However, any suggested colours for the new logo needs to fit in with this kind of business. For examples of their competitors in similar fields, view http://www.clearybros.com.au/ and http://www.trn.com.au/
Possible ideas was that the "O" in the company name may symbolise a large construction equipment vehicle wheel, either the whole wheel, or part of it...... or... a simple line outline of the top of some kind of construction vehicle sitting over the top of the wording "O'Neill" or even sitting to the side of it as its own icon.
The above are only suggestions but you can be as creative as you can be.
