“Houston-based developer Hines says it won’t likely start construction as planned in the first quarter on a mixed-use project it is developing in downtown Austin with the Austin Museum of Art. A Hines spokeswoman says the company still hopes to start construction in 2009. Hines will need to prelease at least half the project’s 425,000 square feet of office space before it seeks financing for the office component, the spokeswoman says.”
