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.

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.
