Who is responsible for designing the construction drawings for frozen refrigerant systems?
Thread Content
Our company has launched a new PVC project, and for the cooling system, equipment from a domestic refrigeration manufacturer is being used, including chillers, evaporators, and evaporative coolers. The flow diagrams were provided by the manufacturer, while the design agency responsible for the PVC project’s design only handled the design of the salt water pipelines. As for the construction drawings for the refrigerant pipelines connecting the chillers, evaporators, and evaporative coolers, the design agency and the manufacturer are passing the responsibility back and forth. We believe it should be the manufacturers who handle this, after all the equipment belongs to them; design institutes are not familiar with the refrigeration processes. What are everyone’s thoughts on this? This post was last edited by edc1233 on 2008-1-30 16:26.]
I agree with the original poster’s view; it should be the manufacturer who is responsible for the design. If a design institute is involved, the manufacturer should at least provide materials such as draft plans and take responsibility for reviewing the construction drawings.
I’ve encountered this situation several times; it depends on how the project is negotiated. Generally, a boundary is established – what’s within that boundary is handled by the manufacturer, while what’s outside it is handled by the design institute. Even if everything is done by the design institute, the manufacturer will still provide fairly detailed drawings, including flow diagrams, layout plans, and specialized drawings for water, oil, instruments, etc. The design institute only needs to make minor adjustments. The above applies to modular equipment; whereas for more discrete devices such as ammonia refrigerators, condensers, evaporators, etc., the design institute designs them based on its own layout plan, with the manufacturer merely providing the equipment.
I think it should be done by the design institute, because on one hand, the project specifications require that the design institute provide the construction drawings, and on the other hand, the manufacturers do not have the qualifications to create such drawings; if anything goes wrong, there will be disputes between them!
My company is installing a 600,000 kcal refrigeration system. The manufacturer provides the sketches, while we design the installation drawings on our own! After all, the system pressure isn’t high, so there shouldn’t be much of a problem, right? :) :)
It should be done by the design institute; the manufacturer doesn’t have the qualifications for installation, I guess.
Does a turnkey supply contract require the provision of construction drawings and construction specifications? Generally, manufacturing plants do not have design capabilities; it is recommended that the manufacturer prepare detailed installation instructions, while the design firm carries out the design of the construction drawings based on those instructions, with the manufacturer giving its approval
Hehe, it’s your approach that doesn’t meet the standards. Design can only be carried out by design institutes; manufacturers do not have the qualifications to carry out design work. However, since no design institute was involved in the refrigeration aspect during the early stages, the design institutes are also unwilling to take on this task. Hehe, now, it can only be the manufacturer to provide the drawings, which are then reviewed and stamped by the design institute!
It’s a lapse in your contract that has now turned into a ¥ issue: the refrigerant circulation pipeline can be manufactured by the manufacturer. It’s not a matter of design capability, but simply an issue with stamping the construction drawings. Moreover, the manufacturer is the best choice, as they are most familiar with their own equipment. Who is responsible for the piping of the complete frozen water unit delivered from the factory? Do we still need to find a design firm? Now that we’re separated, no one will do it! 1. From a contractual perspective, it’s the RMB issue! 2. From the perspective of construction drawings, it is a matter of design qualifications. (It has been disassembled, so it needs to be installed on-site; there are already construction drawings for the piping design.) Do as mentioned above – be firm with them; no need to spend money:$lol
