The Professional Constructor - April 2014
The American Institute of Constructors exists to promote individual professionalism and excellence throughout the related fields of construction. AIC supports the individual Constructor throughout their careers by helping to develop the skills, knowledge, professionalism and ethics that further the standing of the construction industry. AIC Members participate in developing , and commit to, the highest standards of practice in managing the projects and relationships that contribute to the successful competition of the construction process. The American Institute of Constructors believes that its Standards of Professional Conduct are more than simple words.
3D Architectural Modeling: James L. Allhands Essay 3D modeling is extremely beneficial early in the project definition phase. Through 3D 57 coordination of a variety of disciplines, evaluate project Figure they 2 – 3D expect Architectural Modeling modeling, the design team can communicate exactly what in the look and feel sequences before the construction phase of a project, and to provide constructability analysis. The dynamic of the project between themselves and nature of VDC enables the construction industry in due course to see the unforeseen (Khanzode, 2006). also the stakeholders. The 3D model Laser Scanning: Laser scanning uses laser light to capture spatial data by utilizing millions of points with a distinct communication toeach create a shared latitude, longitude, and elevation (XYZ) coordination. A complete model is formed aftercan multiple scans are vision. 3D models be generated to performed in the given area to gather every side of the Figure 2 – 3D Architectural Modeling and efficient method of communication to create a project. Once this is accomplished, all the data sets can establish the design for site improvements, the exterior of a building (Figure 2), and also be compiled to create a 3D model of the scanned area. shared vision. 3D models can be generated to establish Applications of this tool include and are not limited to the design for site improvements, the exterior of a all interior finishes. By incorporating the 2D data, materials, and drawings to create a 3D determining volumes of stockpiled soil and aggregate, building (Figure 2), and also all interior finishes.

Manual measurement processes enhance communication in owner meetings to ensure the product they are receiving mirrors their exact wants have shown to be much mirrors less cost effective compared their exact wants and needs (Architectural Illustration). to laser scanning. Not only are manual measurements and needs (Architectural Illustration). error prone which can ultimately cause the need of Virtual Mock-Ups: extensive rework, they demand a greater length of time Virtual Mock-Ups: to complete (Spooner & Virtual Associates).
