Project Management: Highway Bridge Construction Project Analysis

This project management assignment provides a comprehensive analysis of a highway bridge construction project. It begins with a network diagram illustrating the project's critical path, detailing activities, durations, and float times. The assignment then addresses material resources, listing essential materials like concrete, steel, and asphalt, and emphasizes the importance of efficient material management. Furthermore, it includes a work breakdown structure (WBS) and a resource breakdown structure (RBS) to organize and allocate project tasks and resources effectively. The assignment is supported by a bibliography of relevant sources, demonstrating a thorough understanding of project management principles.

7. Aluminium
8. Rubber
Managing of material is one of the important element needed for project planning as well
as project control. In construction, the materials purchase includes a huge cost. Management of
materials is a problem that the construction industries are facing. The organizations are using
central purchasing as well as inventory control for the standard items. So, the efficient way to
material storage is using the automated system of materials planning. In this particular system,
the production schedule, the inventory records and the component of the product are merged
together to get the items that are to be ordered, when the items should be ordered and the
quantity of product that should be ordered. The calculation for all these materials are done in
simple arithmetic calculations. All the materials should be listed properly so that the construction
manager and the procurement manager is able to manage the materials properly.
