Rob Maguire is taking no chances as cities and property owners ratchet up their attention to public safety to guard against terrorism.

MaguirePartners spokeswoman Peggy Moretti said the company has, installed eight four-ton concrete barriers on the sidewalk along Fifth Street in front

"It's a temporary measure while a more-permanent installation is completed," Moretti said. "It was a proactive measure on our part because we realized the building could be vulnerable to vehicular intrusion."

Moretti said the barriers, the same concrete slabs used to set off construction lanes on freeways, would prevent anyone from plowing into the building. The more aesthetically pleasing permanent barriers will be installed within weeks.
