Dear friend
In connection with your message, the following can be mentioned:
1- You can sign and send the letter individually.
2- One of the methods of sending a letter to the vice-chancellor of architecture and urban planning is in the form of criticism and suggestions, and it is registered in the 137+ system, and the tracking code provided can be tracked until the end.
3- In the registration of stage reports in the description of the demolition stage in the format provided by the municipality and has the following text, and the coordinating supervisor approves it:
I also undertake to obtain phased reports according to the implementation status of the project from other supervisors as described below. Present to the municipality
Actually, the coordinating engineer is responsible for receiving reports from others, and he should be worried, not you.
4- Don’t think that if you send this letter, a miracle will happen immediately and what you want will happen.
5- From the foundation stage onwards (skeleton), you will have access and in the first stage, you are free to see any errors in the implementation, such as: non-observance of the height code, non-observance of the guard structure, non-observance of the cut seam, non-observance of the length of progress, etc. report and register

6_ In 15 months ago, in connection with the non-access of the structural engineer to register the report, when the architect is the coordinator, I wrote a letter to Tehran Municipality, Engineering System, site 137+ and obtained a registration number, despite repeated follow-ups, after 14 They received a phone call in a month and said it was fixed?!
7- Experienced coordinators usually prepare a special form and hold a meeting with the presence of all engineers and take the opinions and get the signatures of the colleagues, so that there are no more complaints.

Therefore, you are not right with the described description, without sufficient information, everyone did not agree with your opinion, and according to your words, call all the architects of the group (for example, architects or indifferent!!!!!!!)!

At most, if your article is logical and can be followed, there is no need to collect signatures and it can be followed.
Otherwise, collecting thousands of signatures will not work.
