On-site cabinet room civil works funding
Thread Content
I’m working on a project currently, and I need to request funds from the civil engineering team for blast-resistant cabinet rooms on site. I have a few questions: 1. Regarding the air conditioning system, should it be the instrumentation team that specifies the requirements regarding room temperature and humidity, with the HVAC team responsible for selecting the appropriate air conditioning units and submitting the necessary requests to the civil engineering team? 2. The outdoor cables in the explosion-proof cabinet room are laid in cable trenches that lead into the cabinet room. Regarding these cable trenches, is it sufficient to use the conduit specifications specified in the instrument-related documentation, with the civil engineering team handling the design of the trench depth and supports? For the wall openings in the cabinet room, since these openings are below the floor level inside the cabinet room, can the instrumentation team refrain from specifying the elevation of the bottom of these openings, allowing the civil engineering team to decide on it instead? 3. Regarding the installation of cabinet room doors, is it necessary for the instrumentation team to provide detailed specifications regarding the door width, height, and the design of the steps?
No one answered? Well, let me just talk about it casually then. 1. For the air conditioning system, the instrumentation team only needs to specify the required environmental temperature and humidity levels as well as the number of air changes; other aspects are to be resolved through consultation between the HVAC team and the civil engineering team. However, the size of the air conditioning room needs to be specified by the instrumentation team to the civil engineering team. So you should first discuss this with the HVAC team to provide them with the necessary details so that they can give you an approximate idea of the room size, which will then allow you to specify the requirements for the civil engineering team. 2. The depth of the cable trench, supports, openings, and the bottom elevation must all be designed and specified by the instrumentation team. 3. The door width and elevation of the cabinet room should be proposed by the instrumentation team, while the steps can be considered by the civil engineering team.
When I was starting on projects, I was also very troubled by this issue
Overthinking it; I don’t know whether the original poster is the designer or the property owner. 1. If you are the property owner, you just need to submit your comments during the review ； There are internal divisions of labor and channels for raising funds within the design institute ； 2. If it is a design institute, the above issues are part of the standard procedures, so there is no difficulty involved. 3. Returning to the main issue, there are mutual requirements for resource support between the self-control discipline and other disciplines. For details, refer to HGT 20636.2-2017: Specifications for the Professional Design Management of Automatic Control Systems in Chemical Plants – Design requirements and division of labor between the automatic control discipline and other disciplines.

The poster is probably new to the self-driving industry
Most of those working on instrumentation are computer experts; designing the cabinet spaces seems to be done in a hasty manner, and the questions asked are quite strange. In any case, they push everything they don’t know to other specialties.
I work for a construction company, and I’d like to offer some suggestions from a construction perspective: it is highly not recommended to use concrete cable trays in the instrument cabinet room. It is advisable to have a fully cemented floor in the cabinet room, with a waterproof coating applied, followed by the application of epoxy paint. In the instrumentation field, cable trays are installed on the floor inside the cabinet room according to the layout of the cabinets, with cables running within these trays. It is aesthetically pleasing, which also makes it easier to add cables in case of future renovations or expansions. If a cable trench is created, and it’s necessary to add more cables in the future, the anti-static floor will have to be destroyed, which is a real hassle.
