What is Civil Engineering? Profession of designing and executing structural works that serve the general public, including: Buildings bridges, canals, dams, harbors, lighthouses, roads, tunnels, and Environmental works (e.g., water supply systems) The modern field includes power plants, aircraft and airports, chemical-processing and water treatment plants, and water-treatment facilities Civil engineering today involves: Site investigations and feasibility studies, Structural design and analysis, construction, and facilities maintenance. The design of engineering works requires the application of design theory from many fields (e.g., hydraulics, thermodynamics, nuclear physics)

What is Civil Engineering? A branch of engineering that encompasses the conception, design, construction, and management of residential and commercial buildings and structures, water supply facilities, and transportation systems for goods and people, as well as control of the environment for the maintenance and improvement of the quality of life. Civil engineering includes planning and design professionals in both the public design professionals in both the public and private sectors, contractors, builders, educators, and researchers. Civil engineering is a professional

What is Civil Engineering? Engineering discipline that deals with the engineering discipline that deals with the design and construction of the physical and natural built environment, including works such as bridges, roads, canals, dams and buildings. Civil engineering is the oldest engineering discipline after military engineering, and it was defined to distinguish it from military engineering Engineering is the application of objective knowledge to creation of plans, designs and means for achieving desired objectives. Technology deals with tools and techniques for carrying out plans.

Building Material Building Material Materials use for construction of buildings, highways, bridges, mostly infrastructure. Any material which is used for construction purpose is called as building material. Natural materials: Unprocessed, raw, minimally processed. Synthetic materials Industrial processing Artificially composed

Material Selection Wood - Lumber, Plywood, OSB, Composites Steel - Shapes, Rebar, Pipe, Cold-Formed, Cable Concrete - Cast, Precast, Grout, Cellular, Mortar Asphalt - Hot-mixed, Cold-mixed, Composites, Emulsions, Cutbacks Aluminum - Shapes, Pipe, Cold-Formed Stone and Masonry - Clay, Concrete Block, Cut-Stone Building materials encompass a wide spectrum of choices. The selection is often based on economic, environmental, availability, or technical considerations. Geography often determines the economic and availability considerations and engineering principals typically control the technical and environmental considerations. Concrete and Steel dominate the building industry; Asphalt, Concrete and Steel the transportation industry; Wood and Masonry are widely used in the residential housing market; and Polymers, Composites, Concrete, Steel and other metals are the bulk of the piping materials. However, all of these materials are used to some extent for constructing civil engineering facilities and buildings. These are conventional materials that are used in construction or building and infrastructure. Each of these materials has many choices within the basic materials as well. e.g.. wood can be lumber sizes, timber, oriented strand board (OSB), composites (Paralam, I-sections), trusses, plywood, particle board, and pressure treated lumber.
