Conducting soil tests to assess load-bearing capacity is essential during site preparation because it determines whether the ground is stable and strong enough to support the intended structure. Understanding the soil's properties, including its composition, moisture level, and compaction, helps in assessing the risks of settlement or failure, which is critical for ensuring the safety and longevity of the building. This information informs the design and construction processes, including the type of foundation required.

In terms of the other tasks listed, while they are important components of construction, they are not considered essential during the initial preparation phase of the site. Installing windows and doors, for example, occurs much later in the construction process after the structure is framed and weatherproofed. Laying down decorative landscaping is also a finishing touch that happens after the main construction work is completed. Building the framework for the roof is part of the structural work, which follows after proper site preparation and foundational work has been completed.
