"We are never going to be perfect, by any means," Mr Beaumont said.
"But we can have better standards and better procedures, I believe."
His family was one of more than a dozen represented at the opening of the commission hearings yesterday, with Justice Mark Cooper commenting that many families were "still in the midst of grief".
"I hope the work of the royal commission will go some way to helping you deal with that grief," Justice Cooper told those at a ceremony to open the hearings.
The hearings are being held in the unusual setting of a community church hall because of the heavy toll the quakes have taken on the city's facilities.
Justice Cooper suggested it was fitting to have a community setting when the quakes had been a "community tragedy".
The names of all 182 victims were read aloud at the outset of yesterday's first hearing, and two minutes' silence was observed in honour of those who died.
Experienced lawyer Nigel Hampton, QC, representing the family of quake victim Tamara Cvetanov, said he would be raising issues around building collapse survival zones, escape tunnels and evacuation procedures.
Mrs Cvetanov spoke by cellphone with her husband, Srecko, on and off for almost three hours, while trapped in the collapsed CTV building before she died.
