Planning of materials in Construction Project managementAravind Samala
Materials management is an important element in project planning and control. Materials represent a major expense in construction, so minimizing procurement or purchase costs presents important opportunities for reducing costs.
Materials management is not just a concern during the monitoring stage in which construction is taking place. Decisions about material procurement may also be required during the initial planning and scheduling stages.
The strength of a material is defined as the ability to resist stress without failure.
It is important to note that High strength and High-performance concrete are not synonymous.
Concrete is defined as High strength concrete on the basis of its compressive strength measured at a given age.
In early 1970’s any concrete mixture that showed 40MPa or more compressive strength at 28 days were design as High strength concrete.
Later 60-100MPa concrete mixture was commercially developed and used in the construction of high rise buildings and long-span bridges in many parts of the world.
For innovation in construction, use video presentations with 3D animations to plan and communicate how a project will be carried out and the timeline. This presentation can be used to communicate with the Client, Stakeholders and Site Team.
a brief research about permeability & durability of concrete with helpful images for civil engineering students
fully made by Amira Abdullah (civil engineering student in Ismailia - Egypt)
We know every structure is designed for a life period.
The existence of the structure after the service life period is very dangerous to its occupants and surrounding buildings .
The building act usually contains provisions that enable local authorities to control demolition works for the protection of public safety and to ensure adjoining premises and the site are made good on completion of the demolition.

Modeling a Global Software Development Project as a Complex Socio-Technical S...Ilia Bider
Presentation at the 10th IEEE International Conference on Global Software Engineering (ICGSE 2015)
Pre-proceedings available at:http://bit.ly/1MBpxWY
Any global software development project needs to deal with distances – geographical, cultural, time zone, etc. – between the groups of developers engaged in the project. To successfully manage the risks caused by such distances, there is a need to explicate and present the distances in a form suitable for manual or semi-automatic analysis, the goal of which is to detect potential risks and find ways of mitigating them. The paper presents a technique of modeling a global software development project suitable for such analysis. The project is modeled as a complex socio-technical system that consists of functional components connected with each other through output-input relationships. The components do not coincide with the organizational units of the project and can be distributed through the geographical and organizational landscape of the project. The modeling technique helps to explicate and represent various kinds of distances between the functional components to determine which of them constitute risk factors. The technique was developed during two case studies, of which the second is used for presenting and demonstrating the new modeling technique in the paper.
Centralized Manufacturing Vs Decentralized ManufacturingAmit Shelke
The global market of bioprocessing companies is highly competitive today, and many manufacturing companies are thinking of revamping their manufacturing strategies. On the other hand, the industry has seen great emergence of novel manufacturing technologies, hence the adaption of such technologies is on the rise. The decision of whether to migrate from centralized manufacturing to decentralized manufacturing or not has become the vital part of strategy for industry driven manufacturing companies.
We have compared these two manufacturing processes and for better understanding, we fetched out benefits of both.

AN EXPERIMENTAL STUDY ON THE AUTOMOTIVE PRODUCTION LINE USING ASSEMBLY LINE B...IAEME Publication
The main aim of an assembly line is to group the different facilities and workers inan efficient manner in order to obtain effective utilization of man power and machine.This calls for uniform rate of production as well as decrease in the work in process
inventory. Hence, this paper attempts to achieve these in an assembly line of anautomotive manufacturing unit using three different techniques such as Largestcandidate rule (LCR), Kilbridge and wester column method (KWC) and Rank
positional weighted method (RPW). All the three methods show better efficiency and acomparison is also drawn amongst the three to determine the best suited techniquepertaining to the current research work
Under this we have proposed a Lean Manufacturing technique which is named as SMED to reduce the Setup time and Changeover time of the manufacturing process in a heavy machine shop.

A case study on productivity improvement of wearing insert and cutting ringIJECSJournal
The objective of this paper is to present case study on a wearing insert and cutting ring for the efficient improvements in productivity with the help of various work Study Methods. In this study productivity is improved through identifying the process that involves the time required for the process as the main reason to achieve the objectives of increasing the productivity. Time and motion study is one of the necessary factors to set a standard target. The study is aimed at identifying the unwanted work processes which in turn increases the time required, efforts as well as the cost of the product. Thus the changes were made in the areas which require improving using work study methods.
