Use of Metal Scaffolding helps with Plumb LinesReally tall metal scaffolding to be used in conjunction with laying the load bearing walls. Since there are no columns being used, extra attention to detail needs to be paid to laying the block work true. The scaffolding helps in this regard as a plumb line is set up and affixed to the metal scaffolding, which isn't subjected to movement as wood scaffolding would be

Metal PlumbA 1 kilo metal plumb weight is used to determine the plumb line, which is affixed to the top of the metal scaffolding. The plumb lines will stay in place during the laying of the block walls.

This shows the relative size of the large cinderblocks along with the crushed stone aggregate that will be used in concrete within every other hole of the blocks. The walls thus created will be load bearing walls, every other hole will be filled with 12mm metal rebar and concrete to make the embedded support columns.

CPAC Pour of Ground BeamsCPAC ready mix cement pour of ground beams. 280 KSC (kilometers per square centimeter) concrete was used as in the floor. CPAC is better than hand mix for large areas since it is poured as a homogeneous unit.
