In November, I join the construction work with the substitute civilian servicemen. As I said before the design of the pond is the most important step during the construction, including the size, the aim, and the traffic flow, as a result having a good design can achieve the purpose of application and management of the pond. During the construction, pay attention in each step is important too, especially maintain the level of the construct. If the level isn’t balanced than it might cause the construction problem, also if there are any problems after the construct is done, it will take more time, more budget, and manpower to repair it.
