Construction Engineer for a few construction questions for local building and site committee.

Being on a tight deadline, I'm looking for an experienced Construction Engineer to help me out with a few construction questions for a local building and site committee. The project involves medium commercial site planning and development, and I need expertise with construction materials and methods. Time is of the essence, and any assistance I can get needs to be provided within the week. Knowledge of building codes and regulations is an added bonus. If you have the experience and availability, I look forward to seeing your proposals.
