Productivity of Column Casting Heavy Equipment in the Construction of 31 Sudirman Suites Makassar Apartment

In the world of heavy equipment construction projects it is important to help complete human work. Tower Crane is one of the tools in the implementation of construction projects. In the implementation of the construction of Apartment 31 Sudirman Suites Makassar, there are 2 Tower Crane tools that operate with limited work time due to covid 19. This research was carried out by direct observation in the field and calculating the real value of the specifications to compare productivity. Tower Crane productivity is the result achieved or output, namely the amount of material moved by Tower Crane with all resources or inputs, namely the time required for material transfer. Based on the calculation results that the productivity of the specification is greater than the productivity of observations in the field, this is due to constraints on the weather that occurs and the equipment operator. For productivity, the average obtained on the 4th floor is 71,544 (%) and on the 5th floor it is obtained that is 73,727 (%).

Smart Helmet-Based Personnel Proximity Warning System for Improving Underground Mine Safety

A smart helmet-based wearable personnel proximity warning system was developed to prevent collisions between equipment and pedestrians in mines. The smart helmet worn by pedestrians receives signals transmitted by Bluetooth beacons attached to heavy equipment, light vehicles, or dangerous zones, and provides visual LED warnings to the pedestrians and operators simultaneously. A performance test of the proposed system was conducted in an underground limestone mine. It was confirmed that as the transmission power of the Bluetooth beacon increased, the Bluetooth low energy (BLE) signal detection distance of the system also increased. The average BLE signal detection distance was at least 10 m, regardless of the facing angle between the smart helmet and Bluetooth beacon. The subjective workload for the smartphone-, smart glasses-, and smart helmet-based proximity warning system (PWS) was evaluated using the National Aeronautics and Space Administration task load index. All six workload parameters were the lowest when using the smart helmet-based PWS. The smart helmet-based PWS can provide visual proximity warning alerts to both the equipment operator and the pedestrian, and it can be expanded to provide worker health monitoring and hazard awareness functions by adding sensors to the Arduino board.

Renovation as a core of conceptual models of relationship for innovative types of reorganization of digitalized cyber-physical systems of construction objects throughout their life cycle

The problem of reorganization, as many types of rearrangement in the dyad ‘man-equipment’ (‘operator-equipment’ in transport; ‘worker-equipment’ in mechanical engineering; ‘tenant-building’ in construction and in housing and communal services), is constantly relevant in a developing society. Modeling of ways and forms of solving this problem, the study of different types of reorganization in the dyad ‘man-equipment’, rationing their characteristics and identifying rational areas of their application in the construction industry of our country has been going on since the first half of the 20th century. Scientific studies of the reorganization problem, the proposed functioning models of each of the types of construction reorganization, formation and improvement of regulatory documents of construction production provide effective activities of construction organizations and a necessary level of quality of processes and results of construction production. At the beginning of the 20th century, the main type of construction reorganization was ‘repair’, which by the middle of the century was divided into three distinguishable categories: repair as such, reconstruction and restoration. Each of these categories has individual properties, characteristics and a range of functioning. The basis for this division was social need. At the end of the 20th century, social phenomena of Russian reality again required a revision of the categories of construction reorganization, therefore, construction science proposed innovative types of construction reorganization (renovation, reversal, recomposition, retreatment, etc.). Each type was a response to a new manifestation of social requirements, all types were equally relevant. Only in the second decade of the 21st century, the urban planning and building production reacted to these achievements of the national building science and chose renovation as a basic type of innovative building. The article discusses a renovation model (П-graph of innovative types of construction reorganization), which allows analysis (downscaling, disintegration) and synthesis (enlargement, integration) of concepts, levels and results of construction reorganization processes.

Examination of Realism in a High-Fidelity Tractor Driving Simulator

HighlightsDescribes the creation of a new high-fidelity tractor driving simulator.Describes the perceived realism of a tractor driving simulator among 99 Midwestern farm equipment operators.Examines how farm equipment operator characteristics affect perceived realism of a tractor driving simulator.Discusses potential improvements for future generations of tractor driving simulators.Abstract. Transportation-related incidents are the leading cause of occupational fatalities for all industries in the U.S., including the agricultural industry, which suffers thousands of crashes involving farm equipment each year. Simulated driving studies offer a safe and cost-effective way to conduct driving research that would not be feasible in the real world. A tractor driving miniSim was developed and then evaluated for realism at the University of Iowa among 99 Midwestern farm equipment operators. It is important for driving simulators to have a high degree of realism for their results to be applicable to non-simulated driving operations. High-fidelity driving simulators facilitate extrapolations made by driving research but should be re-tested for realism when changes are made to the design of the simulator. The simulator used in this study emulated a tractor cab with realistic controls, three high-resolution screens, and high-fidelity sound. After completing a 10-minute drive, farm equipment operators completed a survey and scored four specific domains assessing specific characteristics (i.e., appearance, user interface, control, and sound) of the tractor simulator’s realism using a seven-point Likert scale (from 0 = not at all realistic to 6 = completely realistic). An overall realism score and domain scores were calculated. Farm equipment operators were also asked to provide recommendations for improving the tractor miniSim. Overall, farm equipment operators rated the simulator’s realism favorably (i.e., >3 on a scale from 0 to 6) for all individual items and domains. The appearance domain received the highest average realism score (mean = 4.58, SD = 1.03), and the sound domain received the lowest average realism score (mean = 3.86, SD = 1.57). We found no significant differences in realism scores across farm equipment operator characteristics. The most frequently suggested improvements were to tighten the steering wheel (27%), make the front tires visible (19%), and that no improvements were needed to improve the simulator realism (18%). This study demonstrates that the new tractor miniSim is a viable approach to studying farm equipment operations and events that can lead to tractor-related crashes. Future studies should incorporate the suggested improvements and seek to validate the simulator as a research and outreach instrument.
