“…To address these limitations, Huang et al proposed the Operation Level 4D Model (OL4M), which connects construction virtual prototyping technology to 4D modeling to perform actual graphical simulations [54]; Dawood et al developed a framework that is capable of performing virtual construction site modeling for 4D process analysis [55]; and Adjei-Kumi et al proposed a 4D model called PROVISYS, which uses process information to derive site use processes for resources such as equipment and personnel [56]. Of these, the OL4M process management system [54] is of particular interest as it is takes into account factors such as resources, workforce, equipment, physical space, schedule and materials that are involved in the module manufacturing process.…”

Modular construction methods, where products are manufactured beforehand in a factory and then transported to the site for installation, are becoming increasingly popular for construction projects in many countries as this method facilitates the use of the advanced technologies that support sustainability in building projects. This approach requires dual factory-site process management to be carefully coordinated and the factory module manufacturing process must therefore be managed in a detailed and quantitative manner. However, currently, the limited algorithms available to support this process are based on mathematical methodologies that do not consider the complex mix of equipment, factories, personnel, and materials involved. This paper presents three new building information modeling-based 4D simulation frameworks to manage the three elements-process, quantity, and quality-that determine the productivity of factory module manufacturing. These frameworks leverage the advantages of 4D simulation and provide more precise information than existing conventional documents. By utilizing a 4D model that facilitates the visualization of a wide range of data variables, manufacturers can plan the module manufacturing process in detail and fully understand the material, equipment, and workflow needed to accomplish the manufacturing tasks. Managers can also access information about material quantities for each process and use this information for earned value management, warehousing/storage, fabrication, and assembly planning. By having a 4D view that connects 2D drawing models, manufacturing errors and rework can be minimized and problems such as construction delays, quality lapses, and cost overruns vastly reduced.

Building information models (BIM), through their rich digital information content, have created an opportunity to automate portions of the estimating, scheduling, and visualization processes in construction management. In this research, we are developing a method that applies rule-based spatial reasoning based on the topological relationships between the building components in a BIM to automatically generate a technologically and physically meaningful construction sequencing of the building components while automating association of these activities with BIM objects for purposes of 4D schedule visualization. The spatial reasoning takes into account considerations such as structural construction, material layers and work access, some common construction practices and hierarchical relationships between the building entities. The methodology is applied to the domain of commercial construction projects. INTRODUCTIONThe process of producing working schedules in construction projects is a contextual matter pertaining to the unique project at hand. In the absence of visual aids, such as 3D architectural models, it would require the scheduler to summon their expertise and experience to visualize and mentally walk through the structure to be built, and hence, the process of its construction, to produce the actual schedules. Here, the 2D CAD drawings, contract documents, available resources of the contractor and other relevant data about the project are important inputs to determine the program of construction.These inputs, however, are not in a form that can be fed into a computer program which can apply algorithms to convert them into a schedule to manage the building process. Instead, the scheduler's power of visualization and experience is required to extract the necessary data from the model and prepare a schedule in a CPM format. This process is error prone, time consuming, and challenging especially for beginner professionals. Even after the schedule is created, years of practical experience is required to make full sense of all the information stored in the text and

“…The lack of tools for activity level visualization of construction projects presents problems to planners when considering the future implications of their decisions [1]. 4D/5D-Visualization is an emerging area and presents the ability to simulate the construction process with the additional temporal dimension, which makes the virtual model easy to analyze and plan for the sequence of activities.…”

“…During the past decade, previous research efforts have been made towards advanced fourdimensional 4D planning models by adding the temporal dimension to the 3D animation model. Adjei-Kumi & Retik [1] developed 4D model using virtual reality (VR) technology to support practitioners to plan and visualize their plans.

The construction activity level intricacy makes the whole construction process quite complicated and difficult for planners and builders. 4D (3D+Time) construction planning is a promising area, and it presents the ability to represent the construction process with the additional sequential dimension. It makes the virtual models easy to analyze and plan for the sequence of activities.Traditionally, architectural/construction engineering and technology education, especially construction scheduling has been dependent on bar charts and network diagrams. However, students can hardly understand the schedule-construction progress relationship using a CPM network or a bar chart. Using 4D visualization students can learn time-space relationship in construction schedule more effectively. The objective of this research was to create a user-friendly 5D (3D+Time+Cost) model by adding the cost of project with reference to the time line so that the planners would be able to peg the cost control measures with the schedule. The study provides a structured method and a systematic approach that will enable the students and planners to develop 5D models without worrying about the errors and software hitches. This 5D visualization model will facilitate developing a more realistic approach to the whole construction process. The entire model is integrated to produce an interactive visualization to make the process fairly easier for students as well as the construction industry professionals. In addition to this, changes to the 5D model can be done easily by triggering changes at one level. The techniques demonstrated through 5D virtual construction models can potentially be a valuable tool not only in the classroom, but also as an effective learner-centered self-directed tool to learn planning and construction processes.
