I. Schematic Design
The primary objective for this phase is to arrive at a clearly defined, feasible concept and to present it in a form that achieves client understanding and acceptance. The secondary objectives are to clarify the project program, explore the most promising alternative design solutions, and provide a reasonable basis for analyzing the cost of the project.
Typical documentation at the end of this phase includes:
_ Site plan: Schematic grading, utility, planting and paving plans
_ Floor plans for all levels: Layout of key areas; location and sizing of exits and other circulation areas; basic elevator concepts
_ Building elevations: Schematic elevations fenestration; and preliminary selection of exterior wall materials
_ Key sections
_ Structural: Basis of design; foundation system selection; structural system selection; preliminary framing plans
_ Mechanical: Basis of design; preliminary mechanical systems selection; refinement of service, distribution concepts; input to plans, sections and elevations
_ Electrical: Basis of design; space allocation for electrical systems; selection of lighting and electrical systems; service, power, and distribution concepts; input to plans, sections and elevations
_ Preliminary estimate of construction cost based on current area, volume, or other unit costs
II. Design Development
The design development phase consists of continued development and expansion of the schematic design documents to establish the final scope, relationships, forms, size and appearance of the project. The primary purpose of design development is to further define and describe all important aspects of the project so that what remains is the formal documentation step of the construction contract documents.
This typically includes fully developed floor plans, sections, exterior elevations, interior elevations, reflected ceiling plans, wall sections, and key details. The basic civil, structural, mechanical, electrical, plumbing and fire protection systems should be accurately defined if not fully drawn. No major issues that could cause significant restudy during the construction documents phase should be left unresolved.
The deliverables of the design development phase are similar to those of schematic design. Drawings and specifications that fix and describe the size and character of the project may include:

III. Construction Documents
The construction documents establish the contractual obligations between the owner and contractor, and lay out the responsibilities of the architect and the design team for the project. They communicate the quantities, qualities, and configuration of the work required to construct the project. The contractor uses the documents to solicit bids or quotations from subcontractors and suppliers. The level of detail provided in the drawings and specifications responds to the needs of the project and of those who will own, regulate, and – most important, build it. The documents need to be comprehensive, detailed, and coordinated. Any unclear or incomplete items will have to be negotiated as contract modifications with contractors who are, at the time of bidding, unknown. The construction drawings show, in graphic and quantitative form, the extent, configuration, location, relationships, and dimensions of the work to be done. They generally consist of site and building plans, elevations, sections, details, diagrams, and schedules. The specifications present written requirements for materials, equipment, and construction systems as well as standards for products, workmanship, and the construction services required to produce the work.
