All of the following are benefits of platform construction as compared to balloon construction EXCEPT

Platform construction offers several advantages over balloon construction, making it a preferred method in many scenarios. One significant benefit is the easier installation of plumbing and wiring, which is tied to the way platform construction is structured. In platform construction, each floor has its own separate framing, which provides clear spaces for running plumbing and electrical lines from one floor to another. This allows for more straightforward access and facilitates the installation process, making it easier for contractors to manage these systems.

In contrast, the other benefits highlight aspects of construction techniques and efficiency. Building platforms is often simpler than balloon framing, which involves continuous runs of framing members and can complicate the overall building process. Furthermore, platform construction is easily adapted to prefabrication techniques, allowing for components to be manufactured off-site and then assembled on-site, thus streamlining construction timelines. Cost can also be a factor; while it might not always be less expensive based solely on material costs, the efficiencies gained in time and labor often lead to overall cost savings in real-world applications.

Thus, option D does not accurately reflect the benefits associated with platform construction as it relates to the installation of plumbing and wiring, which is generally more manageable compared to balloon construction.
