Automated Material Management and Handling in Construction Projects

Material Management that is Automated As soon as the building supplies arrive at the CIC job site, they are identified at the unloading area. The inventory database on the job site is then updated. The CIC demands that stocks and the integrated operation of construction equipment be closely monitored. All building materials will be tracked according to CIC from the time the equipment starts working to the time it complete the project. Construction materials can be tracked in two ways: directly and indirectly. In the case of direct tracking, there is a code on the equipment’s surface. These codes are used to directly identify the device.

Barcoding

The United States Department of Defense was the first to use bar coding (DOD). The positioning of thin or wide black bars in barcode symbols aids in the transmission of information. Laser beams and magnetic foil codes are the two main technologies used to read bar codes. The laser beams will make it possible to read bar codes that move quickly. Magnetic code readers are the most reliable identifying system. Recognition of speech Computers are used to identify spoken words in this technology. These words are comprehended, transformed to strings, and then delivered to the computer’s central processing unit (CPU). The computer’s main goal is to handle input patterns and classify them into words and sentences.

There are primarily two steps involved in the process: The first step is to analyse the voice signal. This will aid in the extraction of the voice’s qualities and characteristics. This is learned in a time-ordered manner. Step 2 The phrases are compared to the computer language. Following the comparison, the spoken command is transcribed. Systems for Seeing A two-dimensional image is obtained in the visual system using the vector or matrix method. The image is divided into numerous grid elements, which are referred to as pixels. The grey scale of the pixels provides the binary information required to determine the picture parameter. This is the most common way for the system to recognise items.

Material Handling System that is Automated

The vector approach is used to produce a high picture resolution using contemporary cameras. The picture vectors of scanned items are taken using the Vector technique. These are then archived at predetermined times. The pre-processor evaluates the picture information when a whole cycle is completed. The parameter of interest is taken from this. Material Handling System that is Automated In computer-assisted construction, automated material handling systems play a crucial role. For example, when working with precast or prefabricated components. A material handling system with a material identification system makes construction work easier and faster. The following are some of the most critical components in automated material handling systems: Towlines Cranes are suspended from the ceiling. Systems with inverted power and free conveyors Affluence.

This consists of a powered chain that will allow other carriers to move to their allocated destinations. To regulate the towlines, sophisticated computer electronic techniques are required. This is compatible with a variety of alternative handling systems. The automated material identification system works much better with the towline system. Photoelectric readers or optical scanners can be used to read the bar-coded data and relay signals. The control mechanism directs the cart to its destination. Cranes in the Air There are two types of motorised underhang cranes: Overhead cranes with a single bridge Overhead cranes with two bridges Track, bridge girders, the control package, the end trucks, drive wheels, drive assembly, a travelling pushbutton control, cross-bridge electrification, and the runway make up the motor driven crane.

Inverted power and free conveyor systems

This system is set up in an upside-down position. This includes both a powered and unpowered conveyor system. The weight is supported on a pedestal-type carrier for complete access. System for Self-Driving Dump Trucks The autonomous dump truck system is depicted in the diagram below. This system aids in the functioning of driverless hauling. This aids in the transportation of earth and aggregates by dump trucks, which are ubiquitous on building sites.System for Self-Driving Dump Trucks: A Self-Driving Dump Truck System The autonomous dump truck system has two primary functions: Function for advanced measurement Function of autonomous driving The encoder sensors are fitted to the truck’s tyres to determine the vehicle’s driving distance and velocity. The vehicle’s motion is detected using a fiber-optic gyroscope.

The encoder sensors’ data and the fiber-optic gyroscope’s data will tell us where the vehicles are on the site. A laser receiver or a laser transmitter can be found on the left side of the test vehicle. The reflectors are placed along the vehicle’s driving path throughout the site. These reflectors are spaced 50 metres apart. Long-distance driving can lead to the accumulation of errors. The feedback information provided by the transmitter or receiver installed in the cars is used to fix these. An autonomous car system is utilised to check whether the workers are wearing helmets. This employs a colour image processor to determine whether or not they are wearing it.

System for Automatic Vertical Transport (AVTS)

This is a mechanism for transporting materials around a construction site. With the help of an automated elevator system, the material is automatically loaded. The stuff is hoisted to the designated floor. The lifts will be automatically unloaded by the system. Interlocks make it easier to hoist carriers between crane runways that are close together. This allows the overhead material handling system to cover the most area possible. The interlock system aids in the handling of duplicates. Conveyor systems that are both powerful and free These technologies enable the precast or prefabricated component to be transported using a trolley or numerous trolleys. Conveyors or gravity are used to transport these trolleys. These systems can handle a lot of weight.

Track and drive tube conveyors are used to carry components for prefabrication. A spinning tube is positioned between the two rails in this setup. The speed of the moving component can be regulated by altering the angle of the drive school. When the driving wheel is at the 0-degree position, the carrier remains immobile. The carrier begins to accelerate as the angle increases.Vehicles with self-guiding technology Among all the automatic material handling systems, AGVs are the most adaptable. On-board microprocessors, a central computer, and programmable controllers are used to control these. Because they are not reliant on manual direction, automatic guided vehicles can be termed construction robots.

Handling in Construction Projects

The current manual materials management and control systems are ineffective: they are time-consuming, incorrect, and prone to errors. As a result, there is waste and excess material, as well as delays, decreased productivity, and a lack of up-to-date, real-time information about the status of purchase orders (PO), inventory levels, actual vs. planned material usage, and other issues. The goal of this study was to create an automated model that would solve some of these issues. A field survey was undertaken prior to the development of the model to learn firsthand about the common challenges with materials management and control. The model begins material purchase, tracks PO status, captures material data as it arrives on site and moves across the facility, and generates invoices.
