So, what is the project? I only have experience from the other side of the fence. That is, being on the EC trying to develop some good projects and trying to communicate about them to the owners while having to counter misrepresentation of our proposals by a few owners who object to making any improvements to the site. If the ideas are broadly ‘a good idea’ and your only concern is about process, say, insufficient quotes or project detail, why not talk to the EC members? Indicate that you are not necessarily opposed but would like to understand more about the proposal.
