<text><span class="style10">ivil Engineering (1 of 5)</span><span class="style7">In its aims, civil engineering is one of the most ancient of human activities: it is concerned with altering the natural environment for the greater convenience of mankind. It embraces the design and building of major structures and systems, usually concerned with transport: roads and railways, bridges, canals and tunnels, harbors and airports.The first person to call himself a civil engineer - as distinct from a military engineer - is thought to have been John Smeaton (1724-92), designer of the Eddystone Light- house (1759) in England.Although there were highway links in Mesopotamia from as early as 3500 BC, the Romans were probably the first road-builders with fixed engineering standards. At the peak of the Roman Empire in the 1st century AD, Rome had road connections totaling about 85 000 km (53 000 mi).</span></text>
