Brittany,
This is a very broad topic but, as the previous post says, definitely read the RFP and follow the instructions closely. Most public projects are highly competitive and firms typically have been following the project closely even before it hits the public advertisement.. Adequate consultant responses to RFP’s can be time-consuming and expensive so make sure you realistically evaluate your chances in terms of how your team’s expertise and experience match up to the project’s needs in relationship to the competition. Make sure you go to the pre-proposal meeting with a basic understanding of the project. Good luck, Tom
