Materials and Methods


Building Structure and Foundation Materials and Methods B elow Gr ade • Retaining walls are reinforced concrete. • The steel columns are encased in concrete • The slab over the basement storage 8.75” flat slab with 5.75” drop panels • 5’ by 5’ feet capitals supports (Fig. 1)

Concrete and Steel Str uctur e

Above Gr ade • The building has a steel frame structure with moment resistance frames. (Fig. 2 & 3) • The reinforced concrete joist and slab structure are supported by a steel frame of beams and columns 6.75 X 5.5 Grid (Fig. 4) • The typical floor - 8” concrete joist and 3” concrete slab • The roof structure is a reinforced concrete joist and slab construction Str uctur al stability M onetary Times B uilding was designed to support 6 floors, but only 4 were built. Studies shows that the steel columns and concrete footings, along with the floors, indicate a load capacity of 150 # /sf. over six floors.

Building Envelope and Components The spandrels over the first floor windows are finished in precast terrazzo, the second floor level in art-deco motifs and the third floor in brick cladding


Building Envelope and Components At the roofline, the piers terminate in delightful multiple-plane stone caps that project slightly above the parapet

Building Information Modeling - Revit


Revit Advantages of B uilding Informational Modeling over other drafting software “The idea is to create a 3D model or "virtual" representation of the real physical building. Each 3D element has Information ( referred to as "metadata" ) input into it so that the data can be scheduled automatically, and shared downstream with other stakeholders and team members who may use Revit or other programs such as Navisworks to combine all models from the various design teams” Qamar Ul Islam, Savoir-Faire | Assistant Professor | Revit enthusiast

Revit was used as the primary tool of analysis for the purpose of this assignment. To achieve maximum productivity in a short period of time, work-collaboration was used. This allowed multiple users to work simultaneously to create and develop the building information model. Existing AutoCAD files provided by the planning department of Ryerson University were imported into the Revit model as reference. This allowed to create an accurate B IM model based on the as-built drawings. These are some of many features of Revit which helped us achieve this analysis. • • • •

B uilding Information Modeling Work-sharing

Work sets were established to categorize the development of B IM in the order of construction. The B IM manager developed the base-model structural elements, base building envelopes, standardized doors and windows etc. Thereafter each team member developed the details to create a complete model.

Building Information Modeling Constraints, Element Identity and Documentation

Each element created in Revit has a an Identity and set of data attached to it. This can be the physical properties of the indented material of construction or the quantification. Documentation is no longer manual. The information is already there. All you have to do is extract it.

Building Information Modeling Parametric Components, and 3-Directional associativity

Each element is a 3d object with parameters that can be modified to modify the entity Entire model is a single database with all elements interrelated. The significance of this is that when you make any changes in one location all affected elements will dynamically update. 5050 X 2350
