“…Ali et al studied collision avoidance upon the double lifting of a mobile crane, and Perez et al developed an algorithm for planning collision-free paths among polyhedral obstacles (Lozano-Pérez and Wesley 1979). Other studies include those conducted by Maczynski and Wojciech, who developed a 3D optimization algorithm of a rotating part to secure rigidity of mobile cranes (Maczynski and Wojciech 2003), and Lin and Haas (1996), who developed a double lifting simulation program (Lin and Haas 1996). These studies did not consider the ground contact stability of mobile cranes.…”

“…The lifting plans and crane selection have complex, dynamic correlations, so the influencing factors include not only the duration and cost in terms of construction management, but also the working radius, work efficiency, interference with nearby buildings and other works, quantity, location selection, site installation, and disconnection, all of which should be taken into consideration (Lin and Haas 1996). The optimal mobile crane is selected considering these factors, and a respective plan should be set by step in order.…”

Background: Mobile cranes overturn due to excessive lifting, heavy wind, or when appropriate ground contact pressure is not secured. Such accidents can be prevented by reviewing the force conveyed from the outrigger to the ground upon lifting, as well as the soil bearing force. The stability review of mobile crane overturn is classified into the following stages: reviewing lifting conditions, mobile crane selection and reviewing ground contact stability. However, a precise review of ground contact stability requires expertise and is extremely time-consuming. Thus, this study develops automatic design algorithms for securing the ground stability of mobile cranes for easy and quick stability reviews. Methods: The stability review method and the algorithm models are created in connection with the proposed conceptual process. The algorithms proposed in this study conduct simulations for all possible candidate cases, save the results in a database, review practical alternatives, and select the solution that minimizes cost. To verify the effectiveness of the automatic design model, a case project was selected and the algorithm was applied assuming several conditions. Results: Developed algorithms can select candidate cranes according to lifting conditions and design plates through simulations easily and quickly, and design components required for ground contact plate design are collected to build the database that allows easier and quicker stability review. Conclusion: The algorithms proposed in this study conduct simulations for all possible candidate cases, save the results in a database, review practical alternatives, and select the solution that minimizes cost. Developed processes are useful for analyzing correlations of mobile crane performance, ground contact and soil bearing force reinforcement designs and so forth, and for systematically selecting optimal mobile cranes.

The importance of the utilization of cranes in construction operations has resulted in the development of structured methods for crane selection. Most of these methods are for crane model selection and require the user to stipulate the type of crane to be used for the construction operation under consideration. Availability of a structured method for crane type selection will greatly benefit the overall crane selection process. This paper describes a prototype integrated crane selection tool, called IntelliCranes, designed to assist in both crane type and crane model selection. The key feature of IntelliCranes is the systematic incorporation of subjective and qualitative criteria in crane type and model selection.Crane Selection Neural Networks Adaptive Probabilistic Neural Networks Expert Systems Lifting Hoisting,

“…The fast-track method ensures the reduction of construction time (Hadyll, 1997), however, provides a challenge to the contractor for scheduling construction activities as initial schedules often contain generic information. As industrial plant construction projects involve extremely specialized activities, such as the scheduling and use of multiple heavy lift cranes to place prefabricated modules (Lin & Haas, 1996), BIM was deemed to be an insufficient modeling system. PCL Industrial Management, a large Canadian industrial plant contractor, recognized this issue and developed a Plant Information Modeling (PIM) system using 4D technology to visualize industrial construction schedules.…”

As of November 2012, the Alberta government listed 53 oil and gas, oil sands, and mining construction projects either proposed or currently under construction. These industrial plant construction projects have an estimated value greater than 105 million dollars. A common construction method employed for industrial plant projects is fast-track construction, which is used to reduce construction time. Contractors begin fast-track construction with highly generic scheduling information. This high level schedule turns into a lower level schedule as more detailed information becomes available. From a contractor's perspective, a challenge faced using fast-track construction is the visualization of generic and constantly changing project schedules. This paper discusses the use of a Plant Information Modeling (PIM) system, designed to create a 4D animation to visualize project schedules for fast-track industrial plant construction projects. The proposed PIM system creates a modified project schedule by obtaining specific information from a generic construction schedule. Obtaining the information involves grouping schedule activities in accordance with the level of detail in a 3D model, and the level of detail in a project schedule. The modified project schedule is then used in conjunction with a 3D model to simulate the construction sequence in the form of a 4D animation. This allows for 4D visualization of project activities, installation dates, and crane movements. Furthermore, as engineering reaches completion, the PIM system creates a streamlined channel for schedule information updates to be easily uploaded into the model for a more accurate 4D visualization. Through analyzing a nonmodular construction case study, this paper discusses the successes and benefits of the PIM system for 4D visualization, such as increased productivity, shortened construction time, increased constructability, and decreased field costs.
