Design Development (DD) is the phase where the scheme selected at the end of Schematic Design (SD) is developed and refined, materials selected, mechanical, electrical, structural, etc. systems are defined, and the size and character of the entire project established.
During DD, the plans, sections and elevations are drawn to scale, principle dimensions are noted, the structural system is laid out, and major mechanical and electrical components and distribution routes are located. Critical interior spaces are drawn and elevated for review, and preliminary specifications assembled. Materials selection is finalized, and the Room Finish Schedule developed.
It is important that when DD is finished, the user understands and approves of all aspects of the design.
As in SD, the project scope, cost and schedule are evaluated during DD, and must be in balance before the Construction Documents (CD) are started. Written approval to proceed into CD must be received by the consultant before that phase is started.
Specific Consultant Responsibilities:
The consultant shall review the State's response to the SD submittal, and start DD by making any changes required. The consultant will continue to work with the agency, facility and Real Estate and Construction Services (RECS) to finalize the design. Included in the scope of work is the following:
Review the State's response to the SD submittal, and adjust the project scope as required
Attend and document meetings with the facility and agency user groups, and distribute minutes
Administer the project, document progress, and keep RECS project manager informed
Coordinate sub-consultants work
Refine the Code Analysis
Finalize the design
Finalize materials selection
Submit Design Development Documents to RECS for approval.
