Area contractors might soon have to be as good at contract language as they are at laying cement.

At a Base Realignment and Closure Initiative seminar Monday, construction professionals got a good look at some of the problems they may encounter in the coming years. With more than 200 contractors, suppliers, bankers and government officials in attendance, lawyers from Baltimore-based law firm Whiteford, Taylor, Preston provided handouts and presentations on topics such as security clearance, enhanced-use leases and inflation of material prices. BRAC is expected to bring an estimated $4.5 billion in new construction to the region.
