Houston Fire Department officials told KPRC that the plan for Tuesday is to cut holes in the roof and remove debris with a crane so that crews can reach the bodies. The project reportedly passed a structural inspection on Friday and was due for a second inspection Monday, but the report did not specify if the stairs were the subject of the inspection. 

It is almost one year to the day, Oct. 12, that the Hard Rock hotel in New Orleans collapsed, killing three workers. Authorities were able to retrieve the body of one deceased worker almost immediately, but it took several months to recover the remains of the other two because of the precarious state of the structure.  

As most certainly will happen with the Marathon project, OSHA sent a team to investigate the accident and to determine the cause of the Hard Rock collapse. The agency found that much of the responsibility could be traced back to Heaslip Engineering, which OSHA said under-designed the floor beams on the 16th floor of the structure for load capacity and committed other design flaws. The agency fined Heaslip $154,214, the largest fine among the 10 other businesses cited in the collapse. 

Now that all the bodies have been recovered, an $8.4 million effort to demolish the remaining hotel structure and some surrounding buildings is underway. 

Families of the deceased workers and those injured have filed lawsuits against the companies involved, and local authorities have said that the possibility of criminal charge have not been ruled out. The city of New Orleans has also filed a civil suit against those involved in the project in an attempt to recover more than $12 million in accident-related expenses.
