After a six-hour meeting with the construction company and city officials late Thursday, Jacksonville Fire-Rescue Chief Marty Senterfitt told Channel 4 he is "cautiously optimistic" the Duval County Courthouse will pass extensive fire testing over the weekend and can open Monday.

The $350 million courthouse was to have opened four days ago, but continues to fail tests of its computerized fire control system.

Senterfitt said and others with the city met with 14 engineers representing Turner Construction to brainstorm "positive, upbeat solutions" to get the courthouse open without additional delays.  Senterfitt said everyone in Thursday night's meeting was motivated to find out how they could open a safe courtroom Monday.

The latest rest is set to begin Saturday at 4 a.m. Senterfitt and last 15 hours. Crews should know late Sunday whether everything is safe to open on Monday morning. 

If the testing doesn't go as planned, there would be a further delay n the opening of the courthouse.   City Councilman Bill Bishop said that delay could be up to another month.

Clerk of Courts Jim Fuller announced Thursday night that due to the uncertainty, jury duty is canceled for next week.
