Do you think that if you buy a large LED screen, you can hang it directly on the wall? Last year, a friend of mine installed two screens at the entrance of his store, but the city management sealed it on the day it opened. Let’s chat today,​ ​Things that novices absolutely don’t know about building construction projects​​。

Pour cold water on it first - now 80% of cities across the country require LED advertising screens​ ​Approval first and then install​ ​. I read the news two days ago that a shopping mall in Hangzhou had to dismantle and reinstall a 300-square-meter large screen that had just been installed because they failed to go through the formalities. This is no joke. We must first understand three key points:​ ​Who to apply to, what to prepare, and how to pass the review​​。

1. If these materials are not prepared, they will definitely be ruined.

When I was helping clients go through the procedures last month, I discovered that the requirements in various places are becoming more and more detailed. The most basic three-piece set is:

1. ​​Copy of business license​ ​(with official seal)
2. ​​Venue rental contract​ ​(Copy of property ownership certificate)
3. ​​Screen structure safety certificate​ ​(You need to find a qualified testing agency)

Here comes the point! There is a hidden requirement that makes many people stumble——​ ​Screen brightness adjustment solution​ ​. Nowadays, environmental protection inspections are strict. For example, Chaoyang District in Beijing stipulates that the brightness must drop below 300cd/m² after 10 p.m. Last year, a commercial complex received more than a dozen complaints from nearby residents because of this.

2. Don’t reverse the order of running departments.

It is recommended to follow this route for the least trouble:

1. ​​Urban management department​ ​(Determine the legality of the advertising space)
2. ​​Planning Bureau​ ​(Verify building facade approval)
3. ​​City Appearance Management Office​ ​(Get an outdoor advertising installation license)
4. ​​Power Supply Bureau​ ​(Application for dedicated circuit registration)

Here’s a little trivia: In big cities like Shenzhen and Shanghai, screens larger than 50 square meters require an extra trip.​ ​Emergency Management Bureau​ ​. They mainly check fire escape reservations and emergency power-off devices. Last year, a stadium project was stuck for two months because of this.

3. Never step on these pits during construction

Don’t think that everything will be fine once you get the permit! I have come across several cases recently, all of which were caused by problems in the construction process:

• The thickness of the bracket steel is not up to standard (must be ≥8mm)
• Heat dissipation channels block fire protection facilities
• No lightning protection testing was done (especially in rainy areas in the south)

Here’s a real lesson: A restaurant chain installed screens in a second-tier city because it didn’t​ ​Wind load calculation​ ​, the entire screen was blown and deformed during a typhoon, and the repair fee was three times more expensive than the installation fee.

4. Self-question and answer session

​​Q: Do I need to apply for construction to install screens in rural areas? ​ ​
Now towns and villages in Jiangsu and Zhejiang have begun to strictly control it. As long as it is a commercial advertising screen, even if it is only 5 square meters, you must go through the formalities. However, the approval process will be simplified, and it can usually be done by contacting the local town government.

​​Q: How to deal with LED screens used for temporary events? ​ ​
Special attention should be paid to mobile screens used in exhibitions and celebrations! Must apply 15 days in advance​ ​Temporary road occupation permit​ ​, and must be dismantled within 48 hours after the event. On New Year's Eve last year, a company failed to remove the screen in time and was charged a daily toll for road occupation.

​​Q: Is online agency reliable? ​ ​
It is recommended to run by yourself! Nowadays, many agencies use fake materials to fool people. Last year, 23 cases of forged test reports were found in Shenzhen alone. If you really want to find an agent, you must ask the other party to provide​ ​Ministry of Housing and Urban-Rural Development registration certificate​​。

The editor has seen too many lessons of blood and tears over the years. Let me tell you something from the bottom of my heart: I would rather spend an extra two weeks going through the process than leave anything to chance. Many manufacturers now provide​ ​Construction application guidance service​ ​, for example, a company in Shenzhen we have cooperated with helps customers prepare technical parameter documents from the project design stage, so that the approval rate can be increased by more than 60%. Remember, a compliant screen is a good screen that can make money!
