The Professional Building
Software Used: AutoCAD 2D, SketchUp
The Professional Building is a 2-storey multi-use commercial building located in Mississauga, Ontario. According to OBC, the building falls under Group E (Mercantile Occupancies) and Group D (Businesses and Personal Services Occupancies) since it comprises retail spaces on the ground floor and office spaces on the second floor. The site had already been developed, landscaping and parking planned, and 15 massing alternatives had been presented to us. In a team of two students, we had to develop one of the massing models into design drawings, complete an OBC analysis of the design, and then create representative working drawings.
EXTERIOR DESIGN
Two exterior finishes have been chosen for the building: post red/metallic silver aluminum composite panels and concrete wall panels. The ground floor walls consist of a captured curtain wall system with black aluminum mullions, whereas the second floor has punched-opening windows with black aluminum mullions. Two emergency exit stairs are added inside a structure supposed to look and function as a ‘portico’ for the building. This structure is the primary added design feature and provides additional support to the cantilevered portion of the building.
INTERIOR DESIGN
While planning out the interior spaces, OBC Part 3 analysis was done to account for a barrier-free path of travel, exit requirements, and fire separations. The building core encompasses a male/female and universal washroom; and various other service and building systems-related rooms. The ground floor includes a front desk with a lobby area, a feature stair around a panoramic elevator leading to the second floor, a coffee shop, and 8 retail units. The second floor comprises a front desk with a lobby area, a male/female and universal washroom, janitor room, electrical and data closet, and various staff and support spaces for people working in the office.
STRUCTURAL DESIGN
The building is mainly a sprinklered steel-frame construction. Structural members are beams, girders, and open web steel joists (OWSJ), as spans require. The exceptions are the foundation and the slab on grade on the ground floor, where concrete is used. The elevator shaft and the walls inside the building's core are concrete masonry units (CMU).
