It was assumed that interior steel stud walls were light gauge (25Ga) and exterior steel stud walls were heavy gauge (20Ga).   2.1  Cast In Place         2.1.1 Wall_Cast in Place _Strip Footing_ Basement_M_M • This wall was reduced by a factor in order to fit the 8” thickness limitation of the Impact Estimator for Cast in Place walls.  This was done by reducing the length of the wall using the following equation;  = (Measured Length) * [(Cited Thickness)/8”]  = (44’) * [(10”)/8”]  = 55 (ft)  • 6 mm vapour barrier were assumed for all of the Footing_ Strip_ Basement foundations. 			     2.1.2  Wall_Cast in Place _Strip Footing_ Basement_ G  • This wall was reduced by a factor in order to fit the 8” thickness limitation of the Impact Estimator for Cast in Place walls.

Therefore the interior walls length is what I picked up by walking through the building. 			     2.2.3 Wall_ConcreteBlock_Second Floor_Interior • The interior walls were assumed to be concrete block the same as the exterior walls.  • The ½” gypsum board were assumed on both sides of the interior walls.     2.2.4 Wall_ConcreteBlock_Third Floor_Interior • The interior walls were assumed to be concrete block the same as the exterior walls.  • The ½” gypsum board were assumed on both sides of the interior walls.     2.2.5 Wall_ConcreteBlock_Fourth Floor_Interior • The interior walls were assumed to be concrete block the same as the exterior walls.  • The ½” gypsum board were assumed on both sides of the interior walls. 3 Floor         The Impact Estimator calculated the thickness of the material based on floor width, span, concrete strength, concrete fly ash content and live load.  The assumptions that had to be made in this assembly group were:  1. Live Load  Live load for the main, second, third and fourth floors were assumed to be 75 psi. This assumption was based on the below reasoning  In the drawing the live loads are specified as;  Classroom: 60 psi Corridor: 100 psi Offices: 50 psi   Since there is no option in the Impact Estimator to separate these live loads, The average of the specified live loads was taken which is62.5 psi and 75 psi which is the closet option to it has chosen from the Impact Estimator 45, 75 and 100 psi options.  2. Concrete Strength  Concrete strength was assumed to be 3,000 psi. In the drawings there is no specified concrete strength; however they mention that light weight concrete has been used. Light weight concrete generally has strength around 3000 psi which is the reason behind my assumption regarding concrete`s strength.  3. Fly Ash Percentage  Fly Ash percentage was assumed to be average, as discussed in the lectures.   3.1 Concrete Precast Double T         3.1.1 Floor_Concrete Precast Double T_Main Floor For simplicity the elevation of main floor is assumed to be constant in all classrooms. 			 4 Roof         • Live Load  Live load for the roof of the building was assumed to be 45 psi since it is the closet to the specified live load in the drawings which is 40 psi.  • Concrete Strength  Concrete strength was assumed to be 3,000 psi. In the drawings there is no specified concrete strength; however they mention that light weight concrete has been used. Light weight concrete generally has strength around 3000 psi which is the reason behind my assumption regarding concrete`s strength.  • Fly Ash Percentage  Fly Ash percentage was assumed to be average, as discussed in the lectures.    4.1  Roof_Concrete Precast Double T          4.1.1  Roof_ Concrete Precast Double T_Building Roof   For the building roof 4” Polyethylene built up asphalt roof system with 4 “ fiber glass felt +gypsum for the insulation was assumed.This combination provides a product that is resistant to moisture and mold as well as fire.   5 Door           5.1 Wall _Concrete Block_MainFloor_Exterior The entrance doors for the main floor exterior walls were assumed as windows because they are doors made out of glass. 6 Column and Beam The method used to measure column sizing was completely depended upon the metrics built into the Impact Estimator.  That is, the Impact Estimator calculates the sizing of beams and columns based on the following inputs; • Number of beams, • Number of columns,• Floor to floor height, • Bay size, • Supported span • Live load  Since the live loading was not located within the Lasserre building information, a live load of 75psf on all four floors and the basement level were assumed.       6.1 Column and Beam     			     6.1.1 Column _Concrete_Fourth Floor Small Bay Size For the fourth floor since there are two different span and bay sized. Two conditions for the beam and column section have been created in order to address this size difference. The first set which is the same as other floors and the other set of column and beam which is modeled in the IE as the Column_Concrete_fourth Floor small bay size has different number of columns and beams with different bay and span size.  Because of the variability of bay and span sizes in the fourth floor, they were calculated using the following calculation;  = sqrt[(Measured Supported Floor Area) / (Counted Number of Columns)]  = sqrt[(7101 SF) / (70)]  = 10.1 ft
