SDC COMMENTS - FEBRUARY 2, 2012

• Revise the form, color, lighting and design of the stacks so that they appear continuous when they pierce the roof of the fan room. If the mechanical requirements prevent the stacks from being a continuous form below and above the roof, use light, color and composition to create a design that unifies the pieces into a simple legible form.

• Integrate the design of the head house and its ground and its ground plane with the design of the operations building.

• Review and further refine the joinery of the façade so that its design and patterning of bands and joints is intentional. While the design of the joinery has improved, it needs more fine tuning.

SDC COMMENTS - FEBRUARY 2, 2012

• Integrate sustainability and storm water strategies into the design. Consider placement of the storm water collection on the north side of the building.

• Simplify the detail around the garage doors.

• Remove the apron and its unique paving treatment from the base of the fan room. Consider using a sidewalk pattern instead.

• Recognize that the site boundary will likely shift as the waterfront team moves forward with its planning and design work.
