Requirements for purchasing inquiries regarding control skids

For a foreign-funded project, the client’s request regarding equipment procurement was as follows: All interconnecting instruments, piping, valves, and fittings inside the skid. After conducting price inquiries, tendering processes, and technical clarifications, a supply contract was ultimately signed with the supplier.
Upon arrival of the delivery deadline, boxes of small packages as well as bundles of loose pipes were gradually received on site from logistics and courier services, along with assembly diagrams sent by the supplier. The client is requesting a “control sled” of appropriate size (as shown in the diagram); it’s unclear whether the supplier lacks the capability to manufacture it or failed to understand the requirements After several discussions, the supplier agreed to send someone to install it on-site, but will the product installed there be identical to those manufactured in the factory?
Fortunately, the project is in China; if it were overseas, the manufacturer would likely face huge claims.
How tall is this pry bar? ?
Approximately 1800*600, double-sided.
The size of the skid cannot be made as large or as small as desired; what’s important is that a suitable skid exists on which all the equipment, pipes, valves, and control components can be properly assembled. If the skid-mounted unit is made too large, it leads to waste of materials (increased costs); if it is made too small, the equipment and materials that need to be placed inside cannot fit or operation becomes inconvenient, which is also not acceptable. Let me show you a few skid-mounted examples.
It wasn’t properly clarified, and there was no control over the design and manufacturing processes either.
This is not a matter of clarification; I think it’s a problem resulting from conflicts between domestic and international design and manufacturing philosophies. From a domestic perspective: the design institute prepares the drawings, the pipeline and valve materials are purchased and delivered to the site, and then the installation unit carries out the installation according to the drawings. In foreign countries, due to issues such as high labor costs, design focuses mainly on enabling mass production in factories, with only minimal assembly work on site. In this case, the procurement requirement is specifically to have the components installed \"inside the skid\"; this allows the main instruments, pipes, and valve components to be fully assembled at the manufacturer’s factory, along with undergoing all necessary tests and most of the calibration procedures, thereby reducing the workload associated with on-site installation. It also ensures that the manufacturer provides a complete set of skid-mounted equipment ready for immediate installation.
Could you tell me the dimensions? This black tube is so tall; it must be difficult to transport, right?»
