The term Civil Engineering originally came into use to distinguish from military engineering, Civil engineering dealt with permanent structures for civilian use, whereas military engineering dealt with temporary structures for military use A more appropriate definition of civil engineering is that it deals with the design and construction that are intended to be stationary In practice, this definition includes buildings and houses, dams, tunnels, bridges, canals, sanitation systems, and the stationary parts of transportation systems highways, airports, port facilities, and roadbeds for railroads Civil engineering offers a particular challenge because almost every structure or system that is designed and built by civil engineers is unique One structure rarely duplicates another exactly Even when structures seem to be identical, site requirements or other factors generally result in modifications Large structures like dams, bridges, or tunnels may differ substantially from previous structures The civil engineer must therefore always be ready and willing to meet new challenges Within the field of civil engineering itself, there are subdivisions: structural engineering, which deals with permanent structures; hydraulic engineering, which is concerned with systems involving the flow and control of water or other fluids; and sanitary or environmental engineering, which involves the study of water supply, purification, and sewer systems Obviously, many of these specialties overlap A water supply system, for example, may involve dams and other structures as well as the flow and storage of water In a nuclear power plant, civil engineers are responsible for the design and construction of the plant itself, as well as the protective shielding around the nuclear reactor In the project of this kind, the engineer is a member of a team that is often headed by a system engineer who coordinates the contribution of all members of the team Because teamwork is necessary in so many engineering projects, nowadays, an important qualification for engineers is the ability to work successfully with other people ( Source : Lờ Th Hoi Thao v cỏc cng s, English of civil engineering, tõm bi dng cỏn b, B Xõy Dng , 1997 ) VOCABULARY temporary /'temprri/ (a): tm thi appropriate /'proupriet/ (a): thớch hp structure /'strkt/ (n): kt cu; structural /'strktrl/ (a) dam /dổm/ (n): p nc sanitation /,sổni'tein/ (n): s ci thin, iu kin v sinh roadbed /'roudbed/ (n): nn ng challenge /'tổlind/ (n): s thỏch thc unique /ju:'ni:k/ (a): nht duplicate /'dju:plikeit/ (v): li, lm thnh bn, nhõn ụi identical /ai'dentkl/ (a): ging ht substantial /sb'stổnl/ (a): ln lao, quan trng, thc t willing /wili/(a): t nguyn, sn lũng subdivision /'sbdi,vin/ (n): s phõn nh, phõn nhỏnh, b phn hydraulic /hai'dr:lik/(a): thu lc, chy bng sc nc environment /in'vairnmnt/ (n): mụi trng purify /'pjurifai/ (v): lc, lm sch sewer /'sju/ or /su:/ (n): cng rónh overlap /'ouvlổp/ (v): gi lờn nhau, chng chộo obviously (adv): rừ rng, hin nhiờn result in /ri'zlt in/ (v): gõy nờn, cú tỏc ng ti, a ti kt qu nuclear reactor /'nju:kli ri:'ổkt/ (n): lũ phn ng nguyờn t shielding /i:ldi/(n): tm, lp che chn specialties /'spelti/ (n): ngnh chuyờn mụn modification /,modifi'kein/ (n): s thay i, s sa i military engineering /'militri en'nr/ (n): xõy dng quõn s purification /,pjurifi'kein/ (n): s lm sch, lc sch distinguish /distigwi/ (v): phõn bit originally /'ridnli/(adv): ngun gc, ban u storage /'st:rid/(n): s lu tr,d tr PRACTICE I Comprehension questions: In what way civil engineering and military engineering differ? What stationary structures does civil engineering deal with? Why is civil engineering said to offer a particular challenge? Why must the civil engineers be ready and willing to meet new challenges? What is civil engineering sub-divided into? Do these branches of civil engineering work independently? What are civil engineers responsibilities in a nuclear power plant? What is the role of a system engineer? What is one of qualifications engineers should have nowadays? 10.Why is it an important qualification?
