1.0 INFORMATION TECHNOLOGY IN CONSTRUCTION LOGISTICS Given the short-comings in the current practice of logistics in the construction industry, the importance of information and communication technology (ICT) to achieve improved logistics process cannot be over emphasized. From materials or equipment tracking to operation simulation, ICT will improve adequate information flow, efficient delivery, prevent damage and theft and enhance the productivity of construction process and its participants. There are many ICT devices are available which can be used to efficiently track construction resources through the supply chain to the construction site. Currently, most delivery and inventory data are still recorded by manually and manual handling and…show more content…
Its main functions include spatial analysis, processing map data and some aspects of attribute data. GIS can help to improve reliability through real-time positioning of delivery vehicle. Through GIS, we can gather, process, store, manage and analyze geographical spatial data and attribute information conveniently. GIS is a tool for comprehending geography and making intelligent decision. It organizes geographic data in such a way that anyone using digital map can select data necessary for a specific task. For example, locating a vehicle or routing service personnel on a delivery mission. A good GIS program is able to process geographic data from a variety of sources and integrate it into a map…show more content…
Barcode is a sequence of vertical printed on paper mounted on the case of a product, which can be scanned by a scanner and the information regarding such product is transferred to an inventory database. Such information might include product name, manufactured date etc. Due to the short comings of barcode, which include line of sight requirement and fragility, it cannot withstand harsh and rugged environment like construction sites (Jang and Skibniewski, 2008). RFID system is composed of tags, which carry data in suitable transponders and readers, which decode the data from the tag. RFID tags can either be active or passive depending on source of power. Active tags are battery powered while passive tags are powered by the energy field of the reader. RFID technology overcomes the limitations of barcodes. RFID tags do not require line of sight before they are read, they can be read at a longer range, they are rugged and can survive harsh environment and data on RFID tags are rewritable. RFID system can help to solve the effects on construction process such as inadequate security and protection that lead to material loss though theft or damage from weather. By using RFID system, security through real-time localization of materials can be
