                                        SCHEMATIC DESIGN PHASE



Schematic Design - Transition from Architectural Program to Design

This is the part of the design process where the goals, requirements, and constraints
identified in the Architectural Program are transferred into defined spaces, structures and
systems. The SD Phase is the bridge between the Architectural Program and the initial
three-dimensional design of the project.

Note: If the Design Consultant didn’t prepare the Architectural Program and/or was not
involved in the Architectural Programming process, it is important that key members of the
Design Consultant’s team review and become familiar with the Architectural Program before
starting the SD effort. The Design Consultant must accept or object to the Architectural
Program and basic premises regarding Project scope and cost before beginning work. If the
Design Consultant is required to work from an Architectural Program prepared by others,
their detailed review of the Architectural Program must be specifically authorized in a Project
Agreement.

Alternate Solutions

During the SD Phase the design team develops various design solutions (options) that meet
the Architectural Program requirements. The basic characteristics of the site and facility(s)
are explored and a range of alternative design concepts (usually a minimum of three) are
explored and presented to the County.

Site locations and arrangements, exterior building configurations, systems, interior building
arrangements, etc., are examined and documented by the design team. The purpose of the
SD phase is to describe three-dimensionally the Design Professional’s interpretation of the
Architectural Program. This is accomplished by exploring a range of design alternatives,
each of which is tested against the project criteria established during the Architectural
Programming phase. The resulting SD documents should satisfy all participants that the
best design concept has been identified for further development during the subsequent
design phases.

During development of the SD documents, the design professional must document the
process leading to and the characteristics of the recommended alternatives in a manner that
clearly conveys the design intent to both non-professional and professional audiences.

Scope, Scale, and Relationship of Spaces

The SD documents must illustrate the general scope, scale, and relationship of spaces and
project components to each other. During the SD phase, the building is located in relation to
site elements, spaces are laid out to satisfy adjacency requirements, and the facility is
organized with a logical circulation plan. Approximate dimensions, areas, and volumes are
developed.

Preliminary Selection of Building Systems and Components

Preliminary selection of structural, mechanical, electrical, and other building systems and
materials takes place.

materials takes place.

The PM should ensure the Design Consultant is preparing an “energy features matrix” as
described in the County’s Energy Policy, if such a component of the design is warranted.


Schematic Design Submittal

The specific requirements for the form, format, and content of the SD submittal are detailed
in the County’s Guide for Professional Design Services. Generally, the SD submittal must
include sufficient detail and information to set and/or demonstrate the character, intent and
costs associated with the Project. Typical products of the SD phase, pursuant to PSA 5.04.
C., include:
        Site Investigations, particularly for repair and remodel projects. The PM should note
         that these site investigations are particularly valuable;
        A review of alternative approaches to design and construction of the Project.
        Schematic drawings and study models, if appropriate, to indicate the size, shape and
         relationship of all spaces and systems involved in the Project.
        A narrative report by each discipline describing their proposed design philosophy.
        A preliminary equipment list.
        Perspective drawings, if needed to convey the designer's intent.
        A chart comparing the changes in cost elements and the size of each space from the
         Owner-accepted Architectural Program to the Final SD submittal.
        Preliminary Energy Consumption Report including estimates of annual utilities
         consumption by month for the Project.
        Preliminary Statement of Probable Construction Cost.
        Design Intent Report
        Program Validation Report (Supplementary Services)

Schematic Design Review

The submission of the SD submittal to the Owner is a major milestone for the project. It is
the first time a cohesive design is available for everyone to review. It is essential that the full
project team see the design and buy-off on the basic concepts.
