As someone with extensive experience in the architectural visualization industry, I understand that some terms may be unfamiliar to those outside our field. I aim to provide a clear and comprehensive explanation of the difference between archviz and design revisions, enhancing your understanding of our work.
Let's make this analogy.
Scenario 1
You send construction documents to your builder, who constructs the structure using them without a mistake. Then, they have done their job. According to the construction documents, if the builder builds something incorrectly, then the builder has to correct the error.
Scenario 2
When the designer goes to the construction site and doesn't like something they see, even though it was built as directed, the design might need to be changed. This could be a change in the window's location, a modification in the layout of a room, or a shift in the angle of a roof, which isn't the builder's responsibility. A change order might be initiated, and a fee would be associated with these changes.
Scenario one is an archviz revision, and Scenario two is a design revision.
Changes in the field are often the most expensive, making design revisions costly. Even if fees are incurred for changes in the computer, they are significantly less than those in the field, making them a more cost-effective option and value-added.
You don't need comments if the virtual model is built according to the design documents. The industry standard is two sets of revisions, but that trend is starting to change to one revision. Archviz corrections are corrections made due to errors in translating documents into a 3D model, which are free since the mistake was not the designer's fault. On the other hand, design changes always come with a cost since changes are made from the provided documents.
Consider a designer going to a construction site, asking the contractor to move a window, and disputing the cost of that change. The same can go for paint, tile, flooring, and roofing; almost any change takes time and resources, both in the natural and virtual worlds.
I understand that industry jargon can be confusing, especially if you're not immersed in it daily. Please feel free to contact me with any questions or further clarification. I am here to help.
