Technical assistance: What is the difference between the general contracting qualification for petrochemical construction and that for chemical and petroleum construction?

There should be no difference between the general contracting qualification for petrochemical construction and the general contracting qualification for chemical and petroleum construction； The general contracting qualification cannot cover the specialized contracting qualification.

Bro Ming, does \"not being able to cover\" mean that one has the general contracting qualifications to undertake all tasks within the scope of the contract, but does not need the corresponding specialized contracting qualifications?

A company with general contracting qualifications can undertake all tasks within the scope of general contracting. However, if specialized contracting qualifications are required for certain tasks, such as boiler installation or heavy lifting, then corresponding qualifications for boiler installation or lifting must be in place. If the general contracting party does not possess such specialized qualifications, it can opt for subcontracting or forming a consortium. However, subcontracting is prohibited for the main project; for example, in the case of the general contracting of power plant projects, one cannot take on such contracts without the qualifications for boiler installation, even if they do have the qualifications for general contracting.

Thank you very much. I’m still a bit confused. My company holds a first-class qualification for general contracting of chemical and petroleum engineering projects, but for the specialized contracting services it offers, the qualification for petroleum pipeline installation is of second class, while the qualification for non-destructive testing is of third class. These professional qualifications should correspond to the first-level general contracting qualification, right? Is there something wrong with this first-level general contracting qualification?

Qualifications generally should not be questioned; in business contexts, using fake qualifications constitutes a potential case of commercial fraud. This is something that normal, legitimate companies would not do ； As for his professional contracting qualification in oil pipeline installation, it is at level 2; if the main process pipelines in your project are GC2 pipelines, then a level 2 qualification for pipeline installation is sufficient as well. However, if all the process pipelines in your project require GC1 standards, then the general contractor does not meet the qualification requirements specified in the contract. As for the non-destructive testing being at level three, it doesn’t matter; a third-party professional agency can be hired to carry out the welding inspection.

That’s how I understand it. The general contracting for chemical and petroleum engineering construction includes eight specialized contracting tasks: 1. Installation of chemical and petroleum equipment and pipelines ； 2. Professional contracting for pipeline engineering ； 3. Non-destructive testing ； 4. Corrosion prevention and insulation ； 5. Earthwork and stone work ； 6. Steel structure ； 7. Installation of lifting equipment ； 8. Foundation and substructure. If a company has a first-class general contracting qualification for chemical and petroleum engineering projects, then its eight specialized contracting areas should also all have first-class qualifications. Is this the correct way to understand it? There shouldn’t be a situation where there is a first-level general contractor for construction work, along with second- or third-level specialized contractors, right?
