i came from the building construction yesterday, hoping what can learn some basic knowledge of the construction as well as how to collect files in the working site, but the result was not fruitful, all the people are busying, come and go, which i was sky to ask the qustion form in my mind, eventually i got it hazily, if i wanna be a documenter,i must know clearly of the quality of the raw material, like steel, cement, and beton ect. after gain the qualification test report, hand on to the supervision together with details of the material producer. And know the accruate schedule of the workers, take a note of the weather daily, and fillfiul the working diary, a viral job in the construction field. so i decide to visit that friend every weekend
