IEPNG Deputy President, Ms Finkewe Zurenuoc, made this call yesterday on behalf of the more than 3,000 members of the Institution.
Ms Zurenuoc said the response from Works and Implementation Minister Michael Nali in Parliament yesterday was not true.
She explained the actual amount Alois was referring to was a figure used in 2004 to build a road in a rural area.
She said the suspension was suspicious as Alois has revealed secrets of overpricing of road works in the country.
“Mr Alois has revealed the truth and that’s the reason why he was suspended.
“We cannot sit back and see these sort of political games affect our work.”
She added that Alois was speaking as the President of IEPNG and not a regional Works manager.
Meantime, IEPNG CEO Benedict Mick said the members are all behind their call and that is to reinstate Alois as soon as possible.
“Mr Alois is presenting a paper our IEPNG board approved and not a Works paper.”
Alois was suspended after revealing facts about overpricing of road works at the National Consultative Summit in Lae recently.
