The workers were removing the side forms on sidewalk because the concrete was already dried. We noticed that a worker was cleaning the surface of the slab for sidewalk to be pure cement mixed so that the concrete has no cause of cracking and to fix the sidewalk to the surface of the slab. We also noticed that in every partition on the sidewalk they were putting just like a rubber called filler. The other worker that I noticed was watering the slab and sidewalk for curing of the concrete to be more compact, compressed and tight. For the support of the side forms, we saw that they were welding an iron to fixed to side forms, the essence of the metal support on the side forms was to prevent the forms on its original form or not be deform when pouring a cement mixed on side forms. On the other side of the bridge we saw that the 2 worker was constructing the forms of the T-beam riser. T-beam riser is the concrete where the T-beams put in. when we were getting down the bridge we saw that a worker was grinding the bottom side of the girder, while his buddy was supporting or holding the ladder of what he were step on. After a while we heard a bell ringing sign of we have to be break, after that we go to the rest house and we noticed that there were forms of T-beams on carpentry area and we knew that the process of making T-beams were not on that place to be made, it`s actually made somewhere in Oogong. After the break time all workers got back to their assigned job. They were continuing of what they were doing before. We noticed that a worker was putting some oil on the inside forms of the sidewalk forms to prevent sticking of concrete to the forms when removing from it. We also noticed that a worker applying the anti-rust on the steel form of sidewalk to prevent it from rusting or corrosion. We saw the tying of ties of the railing post. The we saw under the bridge were removing the core bells on bore pile using the acetylene column by column they remove all core bells but not necessarily all. We also saw a worker welding a sheet pile into a curve pattern, they said that it was for slope expansion protection guide to be able to have a perfect curve on slope. Again the workers were doing the side forms of the sidewalk of the bridge while the others were for the supports of the side forms. After finishing the side forms of sidewalk it was poured with mixed cement and we noticed that the constructing of sidewalk was alternating. After the concrete got dried they watered it for curing again. The process of curing was repeatedly until they noticed that was enough. For the concrete railing post we saw constructing of it from tying the steel bars until assembling the forms of it.
