I met with my company surveyor, Mr Azizul in the morning. I found a surveying equipment that i never seen before. It is laser plumb instrument.
The sharpness of the laser can be adjusted by the black knob.
Mr Azizul was adjusting the board with a big cross lines.
As u can see, the laser was at the centre of the cross lines.
Then, Mr Azizul set the total station by using the centre of the board as set point.14-4-2010(Wed)
Activity of the day-concrete casting to Level 3 slab & beam at c/c: E2-J/10a-14a
The concrete G35N(Grade 35) is flow into the concrete pump machine.
The machine is operated by an operator. He will control it to pump the concrete when the concretor order through walkie talkie from Level 3.
The concrete is pumped to Level 3 through these pipes.
The concrete is vibrated by this poker vibrator to let the air out and reduce voids.
The concretors are pulling the concrete to the empty space.
This worker is flattening and smoothening the concrete and makes sure the concrete is in the required level.
This equipment is called mechanical distributor. It make the concrete easier to distribute on large area, save time and save human energy also.
