Which of the following types of construction projects are typically not classified as commercial?

Shipyards are generally not classified as commercial construction projects. Typically, commercial construction involves buildings or spaces that are intended for business activities or purposes, such as offices, retail spaces, and hospitality venues. In contrast, shipyards fall under a more specialized area of construction known as industrial construction. This type of construction is focused on facilities for the manufacturing, processing, or maintenance of products, such as ships in this case.

Office buildings, shopping malls, and hotels are all designed to support commercial enterprises where goods and services are sold or provided, making them part of the commercial construction classification. In contrast, the primary function of a shipyard is not commercial in the traditional sense; it's more aligned with industrial functions, which distinguishes it from the other options listed.
