Assalamualaikum....
Meet again with my 4th day experience at the construction site...
Still at the same site...
Today, my job is recording the piling blows also...
Its seems like a routine job for me because they dont have any helper to record the piling blows...
So as a trainee, eventhough I am not volunteered myself, but as an ordered from my site supervisor I need to take the reading...
Today, I managed to record 10 holes of piling blows...
The piling process cannot be continued because the extension piles are not enough...
So need to wait for the piles to come so then can continue my job as a pile recorder...hehehe....
Around 4pm, going back to the site office and having some discussion with my site supervisor...
We were talking a lot with a subject of "Piling"
He asked me lots of question on piling to make sure I am well known with it...

Here are some information regarding what I am talking about...

Process: Standard Penetration Test (known as piling at construction site)
Weight of hammer used: 3 tonnes
Drop of hammer: 300mm
Piles: 9m(starter with pile shore), 9m(extension) and 6m(extension)
Total depth of the piling process: 24m + 2m of dolly = 26
Dolly: It is a steel pile used to drive pile inside the ground based on the depth required because sometime the required depth cannot be achieved due to the piling hammer cannot go inside the ground for example 2m in this situation. So, dolly will be used to help the hammer to drive more the extension pile inside the ground until achieved the required depth.
Time required per hole: 5-10 minutes
workers: A piling crane driver and his helper
