From page 6... ... 6 This chapter documents the information collected from the literature review of technologies for highway construction delivery. The objective of this chapter is to set the background and context for the findings from the survey and the case examples presented in Chapters 3 and 4, respectively. Read the entire page →
From page 7... ... Literature Review 7 A wide range of technologies exists that directly link to digitalization and visualization. This section discusses the following visualization and modeling technologies and applications: • LiDAR, • Building information modeling (BIM) Read the entire page →
From page 8... ... 8 Emerging Technologies for Construction Delivery One of the key benefits of LiDAR technology is that its acquired data are useful for several applications. The collected data using LiDAR can be mined for additional information to serve as suitable input for different applications. Read the entire page →
From page 9... ... Literature Review 9 Building Information Modeling BIM is the intensive process of developing and using a computer-generated model to simulate the phases of a construction project digitally. The model can include simulation of planning, design, construction, and maintenance and operation of facilities and structures. Read the entire page →
