Ann: FBR Corporate Presentation - July 2020, page-2

Key assumptions:
Hadrian X® manufacturing cost at scale: $1 million
Hadrian X® crew: 2 people per 12 hour shift
Hadrian X® useful life: 12 years
Number of 12 hour shifts per year for Hadrian X®: 252
Hadrian X® maintenance and fuel cost per year: $175,000
Hadrian X® laying cost excludes corporate overheads
Standard double brick house has 351 vertical sqm of wall (237m2 internal facing and 114m2 external facing)
Manual bricklayers work in a crew of three (two bricklayers and one labourer). Crew lays 1,000 maxibricks per eight-hour day. Equivalent to 108 standard bricks per hour per person
Manual maxibrick laying cost, taking one to two weeks (laying only) would be $24-$48/sqm wall laid, with the range dependent upon at which point in the supply and demand cycle the
laying occurs
Hadrian X® average laying speeds are examples only
