RED BRICKS AND LIGHT BRICKS COST ANALYSIS FOR WALLS AND MILD STEEL AND WOOD FOR ROOF TRUSS ( BPN office construction case study in Mojokerto regency)

Abstract

The fast growth of infrastructure requires the need of advance science and technology. Moreover, the
development of building materials recently are more advanced, begin from replacement brick with light brick
or floor plat replaced with lightweight cover, the metal deck, then a roof that no longer use an easel tripod,
the lightweight steel roof truss. To compare the economic value of the current building materials, it needs a
study on the material and installation price comparisons; for wall, it needs the comparison on the brick
materials and lightweight brick, as both materials have many advantages and are easy in installment. This
study is also to analyze the cost of wood frame construction and roof construction price of mild steel frame /
Truss in buildings that are commonly used, and finally, to compare the costs of each structure from both
materials. The study on BPN office Mojokerto regency finds that the consumption of the brick wall material
is much cheaper Rp 30.386, - per m2 or Rp. 169.184.690, for all building wall compared with the
consumption of lightweight brick. Whereas the wooden roof frame is cheaper Rp 11.349.724 , - for all roof
frame building compared with the material of mild steel / truss . This study focuses on the cost of materials
and installation. Other costs and Installation time of both types of materials are not analysed.
