# BIM-Based Method for the Verification of Building Code Compliance
## 2 Materials and Methods
### Case Studies  
To prove the concept and apply the developed method, two different case studies have been selected in two different Brazilian locations. The aim is to prove the method's applicability and functionality for different building types with distinct local requirements.  
Thus, the first case study (Figure 3) consists of a one-level single-family residential building (SF building) located in Vila Velha, Brazil. It has some of the most representative characteristics of Brazilian houses--a detached single-family house, with a colonial ceramic tile roof and ceramic brick masonry walls. The house has 2 bedrooms, a kitchen, laundry,

dining room, living room, balcony and garage (each compartment area is described in Figure 3). The construction is located on a plan site of 280.00 m\({}^{2}\) and has a gross construction area of 72.23 m\({}^{2}\), a permeable area of 141.27 m\({}^{2}\) and a projection area of 100.99 m\({}^{2}\). The distances between the building and its limits are also presented in Figure 3, where it is possible to identify the 8.00 m front offset, the 3.35 m back offset and the lateral offset, which ranges between 2.80 m and 2.85 m. Concerning the ceiling interior height, it ranges between 240.00 cm and 270.00 cm for interior areas, while the garage has a height of 300.00 cm. The total building height is 4.05 m, while the total window area is 9.12 m\({}^{2}\), corresponding to 12.63% of the floor area. To access the building, there are two different ramps--one for vehicles (garage) and another for pedestrians--with 1.39% and 8.33% respectively.  
For this project to be approved by the Vila Velha city hall, it must comply with the norms and rules defined in Vila Velha's Municipal Master Plan, for this building typology--single-family residential buildings--and location--Priority Occupation Zone 03 (one of the city preferential zones for residential occupation).  
The second case study (Figure 4), is a multi-family residential building (MF building) with 7 levels, located in Florianopolis, Brazil. The building is inserted in an 800.00 m\({}^{2}\)

site and has a total gross construction area of 1732.56 m\({}^{2}\), a permeable area of 334.99 m\({}^{2}\) and a projection area of 303.50 m\({}^{2}\). The building is intended for residential use and has a service area on the 7 th floor, as well as an entrance and common areas on the ground floor. The building has also a basement for garage purposes, which is accessible through a vehicle ramp with a 15.00% slope. The building has a total of 10 dwellings and a total height of 20.30 m. Regarding the building implementation, it has a 4.12 m front offset, a 7.18 m back offset and a lateral offset ranging between 3.80 m and 5.15 m. Each residential level is composed of two dwellings, as presented in Figure 4, with approximately 122.76 m\({}^{2}\) of floor area each. Each apartment is divided into several rooms: two bathrooms, three bedrooms, a kitchen, hall, laundry, living room and a balcony. The room's interior height is 270.00 cm for every dwelling, which has a window area of 14.76 m\({}^{2}\), corresponding to 12.02% of the floor area.  
For approval, this project must comply with all Florianoplis building code and master plan standards for this building typology--multi-family residential building--and location--AMC 12.5 Zone (central mixed area).
