A.2 Performance Expectations Matrices
At the beginning of each project, the GSA Project Manager, tenants and design A/E need to define the functional objectives of a project. A functional objectives matrix, similar to the one shown in Figure A-1, while not required, may be an effective tool to define these objectives. (Such a matrix may also exist within the project’s design programming documents.) By providing a numeric impact weight (e.g. 1-3, where 3 is high) at each intercept, a graphic check list becomes apparent as to which systems/features are most important in delivering a project’s performance expectations. The high impact matrix intercepts call for design solutions that will optimize functional interests, consistent with the need to integrate solutions that will support all functional objectives.
High impact intercepts require formal design team technical discussions to help optimize design solutions. These technical discussions shall take the form of either a pre-concept design charrette and/or through a series of design team technical meetings during the concept phase. The technical discussion agenda can be organized by discipline (systems) and/or by functional objective heading, but should address:
- Functional performance goals
- Integrated solution options
- Heading-off what can go wrong
- Inspections/certification requirements
- Coordination of construction and turnover-phase issues/deliverables
For both the design concept and design development submissions, the design A/E shall identify the attainment of building functional objectives as represented by the matrix. This shall take the form of a narrative report that by system indicates how the proposed design supports expected building performance.
The Functional Objectives Matrix can be further refined by establishing a matrix for each expectation, e.g. that provided for Sustainability, in figure A-2.While not required, these matrices may help ensure a comprehensive response to functional objectives by breaking down each major function into its component principles/objectives. Sample matrices for Productivity, Security, and other functional objectives are available upon request through the Office of the Chief Architect.
