These are initial drawings and visual representations of a proposed building design. They can include sketches, floor plans, elevations, and other basic drawings to communicate the design intent to the client. Renderings can be 2D or 3D and can show different design options, color schemes, and lighting conditions to help clients visualize the final project.

These are the technical documents that provide detailed information about the building design, including dimensions, materials, and construction methods. They are used by contractors and builders to construct the building accurately and efficiently. Construction drawings may include architectural, structural, electrical, plumbing, and mechanical plans, sections, and details. They are typically prepared after the conceptual design phase is complete and provide the necessary information for the construction phase of the project.
