responsible for a job

in supervising something our work must be extra and firm against the workers so that they work in accordance with the specifications and good quality such as in the employment contract like the example below, I was forced to send out the channels they made so that because the concrete quality did not match the specs, I did not accept such work because I did not want to be a problem in the future

I have confirmed some work with specifications on the contract several times, I do not accept it if they do not want to accept my direction, I have to tell you to dismantle or I do not sign when withdrawing money.
we always give instructions when there are obstacles in a job contact us
we will come and we discuss together with problems in the field can be resolved

whatever the problem in the field, let's finish on the field together so that the vulome changes occur in the field, we can direct new work so that vulome is enough

the plan where we are standing will be built in a dam construction to be able to drain the water to the channel that I told to unload
