GOAL: REFINE & DEVELOP DESIGN SO MOST MAJOR DECISIONS ARE MADE. PRELIMINARY LAYOUT OF STRUCTURAL & MECHANICAL SYSTEMS.
FINALIZING THE DESIGN
The design development phase includes finalizing the size
of the rooms and spaces, refining the look, selecting
materials, determining the systems, and deciding on door
and window types and locations. This phase may also
include several owner/designer meetings, which are
critical to finalizing decisions so the detailed documentation
can begin in the next phase.
SYSTEMS CONSULTANTS
During this phase the systems consultants design and draw
up their portions of the work. For a list of potential
consultants, see the consultant coordination section of this
guide. Our job is to coordinate the work of these various
consultants and implement their drawings into the design.
​
DOCUMENTS
At the end of the design development phase the documents from the schematic design phase have been updated in further detail. It is common to also have the following documents:
-
Outline Specification: Preliminary written description of the project’s major systems and materials.
-
Key Interior Elevations: Drawings depicting the relationship and material choices of the project’s interior rooms.
-
Reflected Ceiling Plans: Drawings of the ceiling depicting locations of lighting, equipment, & level changes.
-
Interior Schedules: A preliminary list of the type and location of interior finishes.
-
Key Details: Preliminary Large scale drawings of specific elements within the project.
-
Systems Consultants’ Drawings: May include structural, civil, and mechanical drawings.
-
Revised Cost Estimate: A revised estimate by a contractor of the cost of construction based on the current building design.
