As per Dr.Soontorn’s email sent to me, I will simply answer your way of project management.
Could you please recall about yesterday’s incident? Our Engineer, K. Pan had requested you to help him for getting some machine to install purlin for one hour, but you had refused his request.
So, is that the way of coordination, and you should have the authority and a way to help each.
Please study more about project management and it is not just sending emails saying , you have not done etc. We feel, that M/S TSA even could use just a laborer to do your job, if you do not have any authority.
Also, could you please explain what is the base for “effect of the schedule” for coming payment? Is that mean, you are going to deduct our payment even we have done the work. Please let us know in-writing if it is the case, and you do not have any right to do so, and you did the same before. However, I will stress out that it would lead to another problem if you try to cut our progress payment without any proper reason and in this contract there is no any term to hold our money based on the duration, however only the work done.
Please note that if you do not pay us the progress payment, any further delay would be due to you as we cannot get the material supply as we planned.
I am sorry for making you in trouble, but this is the truth.
