ARCH 653 - Building Information Modeling: March 2016

1 Project Overview

One World Trade Center (1WTC) is in New York, NY. The One World trade center is commonly referred to as "Freedom Tower". It is the tallest building in the western hemisphere, and the sixth tallest in the world. Construction of 1WTC began in 2006 and was completed in 2014. The architectural firm who designed it is Skidmore, Owings and Merrill.

2 Modeling Process

2.1 Parametric Mass Model

For my parametric mass model, I created the model in four different parts. The base form and middle form were created using extrude. The base form has four isosceles triangles, one in each corner. The middle form begins with the square from the base form. There is a square rotated 45 degrees at the top that will be the roof. It is slightly smaller than the base square. In the middle there is a hexagon half way between level 2 and level 4 on level 3. Level 2 is at the bottom of the middle form, level 4 is at the top of the middle form. The last two forms are the ring sitting on top of the roof and the antenna. The ring and the antenna were both created using loft. The ring was created by first created a cylinder a radius set as a parameter. Then I created a small cylindering with a set parameter in the middle and voided the object. The antenna was created by having a circle at level 4 and then a smaller circle on level 6. Each form has prescribed parameters that can be changed under family type properties to adjust the size of the building. In Figure 1, below you can see the different parameters used.

2.2 Parametric Curtain Panel and Building Façade

I created a curtain panels for my project, it is a square panel with a glass bottom. You can see a picture of each of the figures below. Once I created the parametric curtain panel, I began creating the façade. This was done by dividing the surface and changing the number of U and V grids. I then assigned the curtain panels I created to divided surfaces.

2.3 Creating a BIM Project

Once I finished the façade of my model I imported the family into a project. From there I was able to create curtain panel walls, floors for the building, roof, etc. Then I began creating a interior layout for the 50th floor. I included interior walls, doors, and furniture. You can see a interior rendering below in section 5.
