The delay in transportation of ready mix concrete has become a common issue in civil engineering construction industry which wasted millions of rupees. This report is prepared as a part of the research conducted on developing a GIS based tracking system for truck mixers and a system to find the best route in transporting ready mixed concrete. Furthermore, it focuses on determining (VRP) feature in network analysis extension in ArcGIS. A shape files of road network in Colombo area was created using an open street map. The road network was mapped on the open street map shadflies using polylines. For this research, batching plant established in Colombo 14 and three construction sites in Kollupitiya and union place were considered. Relevant coordinates for both batching plant and the construction sites were imported to the map. Before caring out the final simulation, various constraints were assigned to ready mixed plants as well as for the routes such as one way restrictions etc. The traffic flow of the specific routes has been observed in two time frames such as normal peak hours (07:00 hrs. to 20:00hrs) and off peak hrs (20:00hrs to 7:00hrs). The main objective of this research is to developed an optimum delivery plan for truck mixers by using Arc GIS software and provide a guideline to develop this concept to be used in a much larger scale for beneficial of construction industry Keywords ArcGIS; ready mixed concrete; tracking system; Network planning

  Average skidding distance for forest stands is an important parameter for the determination of the optimum road density and spacing. In this research the real mean skidding distance and theoretical mean skidding distance were measured to calculate the correction factor of skidding distance for Chafrood forest in Hyrcanian zone. The length and azimuth of skid trails from road and depot junction to forest interior were measured. Moreover, the position of skid trail was recorded by GPS. These skid trails with a buffer of 140 m were designed on a topographical map using Arc GIS software. Results indicated that the road spacing of 500 m in the study area resulted in a theoretical mean skidding distance of 125 m. For a real mean skidding distance of 525.9 m and for the mean slope of 40%, the correction factor was estimated to be 4.2.

OpenStreetMap (OSM) is the largest spatial database of the world. One of the most frequently occurring geospatial elements within this database is the road network, whose quality is crucial for applications such as routing and navigation. Several methods have been proposed for the assessment of OSM road network quality, however they are often tightly coupled to the characteristics of the authoritative dataset involved in the comparison. This makes it hard to replicate and extend these methods. This study relies on an automated procedure which was recently developed for comparing OSM with any road network dataset. It is based on three Python modules for the open source GRASS GIS software and provides measures of OSM road network spatial accuracy and completeness. Provided that the user is familiar with the authoritative dataset used, he can adjust the values of the parameters involved thanks to the flexibility of the procedure. The method is applied to assess the quality of the Paris OSM road network dataset through a comparison against the French official dataset provided by the French National Institute of Geographic and Forest Information (IGN). The results show that the Paris OSM road network has both a high completeness and spatial accuracy. It has a greater length than the IGN road network, and is found to be suitable for applications requiring spatial accuracies up to 5-6 m. Also, the results confirm the flexibility of the procedure for supporting users in carrying out their own comparisons between OSM and reference road datasets.

The study of contract labour and its implications for industrial regulation has been neglected in Australia. As an initial attempt to remedy past neglect, this paper offers an account of contract labour (in the form of self-employed o wner-drivers) and its regulation in one section of the road transport industry, namely, the delivery of ready-mixed concrete in the Sydney metropolitan area. This industry represents an unusual example of contractors becoming strongly unionised and establishing an effective pattern of joint regulation over their rates and conditions. The close relationship between the contractors and the Transport Workers Union has also led to the industry playing an important role in the wider struggle between unions and employers in New South Wales over legislation designed to regulate contract labour.

The Road

In the last decade, in the context of debates about climate change, the Australian road construction industry has focused on increasing efficiencies within road construction processes. This approach to environmental impact management is congruent with existing (road-centric) trajectories of infrastructure development. At the same time, however, it also institutionalises the systemic environmental impacts of the road network. This article examines the historical conditions within which this focus on construction efficiencies emerged as the basis of practical action. Firstly, it examines the neoliberal strategies that led to the privatisation of the Australian road construction industry in the 1990s. Secondly, these Australian road industry strategies are compared with other industry-centred harm-management initiatives and traced back to the tobacco industry tactics of the 1950s and 1960s. Finally, this article argues for a broader, interdisciplinary approach to the analysis and management of environmental impact.

By integrating the vehicle tracking system, discrete-event simulation algorithm, and evolutionary optimization algorithm, we developed HKCONSIM-Realtime, a decision-support platform created specifically for handling ready-mixed concrete operations. This platform is capable of (1) tracking the positions of concrete trucks and monitoring the motion and status of concrete deliveries in real time, (2) transforming the tracking records into data that provide updated input to simulation, and (3) optimizing the operations and logistics of concrete production based on simulation of the production system using the most current data. This paper presents an overview of the design and development of (1) the hardware and software modules, (2) the data flow and processing throughout the system, and (3) the role of the system in providing interactive, effective support for the human operator to attain cost efficiency. Case studies are given to demonstrate the functionality and application of the prototype system. Key words: simulation, optimization, vehicle tracking, construction planning, ready-mixed concrete, Hong Kong.

Flood Prone Areas

The Moroccan road network has a linear of more than 57,000 km divided into national, regional, provincial and unclassified roads. Population growth, the transport of goods and the mobility of people require the construction of new links between regions and the maintenance of existing ones. Indeed, several factors, such as rainfall and floods, can cause enormous damage to existing infrastructure. Among the most at-risk areas is the GHARB region, especially the province of Kénitra, represented in this study by Provincial Road RP4209, which includes flood-prone areas with abundant watercourses, associated with poor type of soil. To mitigate these phenomena and to try to reduce their impacts, in particular on the components of a road, one of the appropriate solutions remains the treatment of soils. This process is increasingly practiced in the construction industry, improves the geotechnical and mechanical characteristics of soils without having to go through the contribution of materials from other regions, all for the purpose of a valuation of materials in place by treatment with lime, different hydraulic binders, or industrial products, which will provide an economic and environmental gain
