Miami-Dade Mayor Carlos Gimenez has tweaked procedures for visitors to enter his office on the 29th floor of County Hall.
Before, all visitors who were not county employees had to fill out a sign-in sheet. Now they will also have to wear a visitor's badge.
The policy change is intended to beef up transparency and security, the mayor's office said.
But — privately at least — word among the robust Miami-Dade lobbying corps is that the move was in response to having some in their ranks get too comfortable on the 29th floor.
The mayor's office has been heavily lobbied recently by both sides vying for a lucrative sewer-repairs contract that has become mired in controversy. Bidders AECOM Technical Services and CH2M Hill have hired lobbyists close to Gimenez and his past political campaigns.
Gimenez said only that no particular incident prompted the procedural review.
"We wanted to tighten up on who was coming in and all that," he said.
