2. Schematic Design (SD)

 SCHEMATIC DESIGN (SD): During this stage, architects and engineers create a number of rough sketches and drawings to show the design's fundamental ideas. At this point, preliminary investigations into local compliance and regulations are also finished.

 At the end of this stage,AEC professionals obtain:

✓ All-level floor plans with standard plumbing fittings and openings

✓ Elevations of outside buildings showing representative openings and finishes

✓ Construction cross-section

✓ An ordinary wall portion

With the owner's approval, architectural engineers proceed to the following phase.

3. Design Development (DD)

 The results of the schematic design phase are gathered and advanced throughout design development.

 Finalizing the design and specifying elements like materials, window and door placements,and general structural features are all part of this phase.

 At the end of this stage, construction professionals get:

✓ Floor plans including suggested design openings and plumbing hookups

✓ Overall measurements

✓ Dimensions of the structural grid

✓ Internal wall measurements

✓ Elevations of the outside showing the suggested design openings and finishes

✓ Additional structural components

✓ Wall sections under all common circumstances

✓ Common details

✓ Additional information to create a foundation for design items

Architectural engineers now use written specifications and drawings to give the project's vision form.
