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.

Plumb and Helper LinesThree lines are used at each corner, one plumb line along with a line to set the straight line for that particular side. The lines are clear lengths of heavy gauge fishing line.

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.

Concrete VibrationConcrete vibrated as it is poured into the ground beam. Vibrators are necessary to ensure that the concrete doesn't have voids and settles evenly though out the form.

CPAC Quality ControlCPAC Quality Control staff take a sample of poured cement for a compressive strength test. They will let it dry for 2 weeks and then remove the concrete sample from the form. It is taken to a testing center where the stated KSC (Kilograms per Square Centimeter) compressive strength specification of the concrete is tested. A report will be generated.

Floor pour set-upThe prep for the pour of the floor. Note the spacers and wood that will be used to indicate floor depth. The plastic under the rebar frame is the damp course which will seal the floor and ground beam and protect them from ground moisture.

Rebar Floor MeshingThis is a scale shot which shows the 6mm rebar meshing used in the floor pour. Additionally, note the spacer and the piece of rebar that extrudes from the ground beam, which is used to secure the floor mesh in place.
