During a field test, a shelter was transported in four vehicles and assembled in about eight hours, Milke told Puls Biznesu.
The work required two people and an operator of a small hydraulic truck-mounted crane, he said.
He added that traditional structures require 16 trucks, a 50-tonne crane and 15 workers, while construction takes three days.
The technology is being tested in cooperation with the Military Institute of Engineering Technology in the southwestern city of Wrocław.
According to Puls Biznesu, tests have already examined the resistance of individual elements to fragments from 155 mm artillery shells and the resistance of the entire shelter to blast effects.
The durability and functionality of complete shelters will be tested next.
ARX Modular plans to go commercial with the technology without investing in its own production or construction facilities.
The founders said they want to work with Polish construction contractors and domestic prefabrication plants.
They told Puls Biznesu they expect the technology to be ready for the military market by the end of this year or early 2027.
The announcement comes as Poland seeks to strengthen its civil defence preparedness amid Russia's ongoing war in neighbouring Ukraine and warnings of possible escalation against countries supporting Kyiv.
