The lawsuit alleges that cost-cutting measures led to the use of inferior materials and that the companies were aware of concerns by workers that some of the materials used were too "thin."
"This major building collapse would not have occurred, but for the negligence and failure of the defendants," the lawsuit said.
The collapse on Saturday left two people dead and dozens more injured. One person, a worker, was still unaccounted for as of Wednesday and authorities said the chances of finding the person alive were slim.
The companies named in the suit are 1031 Canal Development, Kailas Companies, Harry Baker Smith Architects, Heaslip Engineering, and Citadel Builders. None immediately responded to ABC News for comment.
Rene Rocha and Steve Herman, the attorneys representing the 10 victims, said all of their clients are still receiving medical treatment and were not available for comment.
"Some are more shaken up than others, but everyone is shocked," Rocha told ABC News on Thursday.
Rocha said they are still working to understand what happened.
"We're gonna do everything we can for our clients to get to the bottom of what happened and to make sure that those who are responsible for this tragedy are held accountable," Rocha said.
Regional Mechanical Services, an air conditioning contractor in Louisiana, identified one of the two people who died as Quinnyon J. Wimberly, an employee of theirs.
"His passion, reliability, and energetic nature were known and enjoyed by everyone he met," the company said in a statement on Facebook.
New Orleans Mayor LaToya Cantrell urged the public to continue to avoid the area.
The city's Fire Department Chief Timothy McConnell said Monday the building remains dangerous and unstable.
"We're a long way from being in safe mode," McConnell said.
