A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.
- Douglas Adams
Aeroplanes are not designed by science, but by art in spite of some pretence and humbug to the contrary. I do not mean to suggest that engineering can do without science, on the contrary, it stands on scientific foundations, but there is a big gap between scientific research and the engineering product which has to be bridged by the art of the engineer.
- British Engineer to the Royal Aeronautical Society, 1922.
A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible
- Freeman Dyson
A great bridge is a great monument which should serve to make known the splendour and genius of a nation; one should not occupy oneself with efforts to perfect it architecturally, for taste is always susceptible to change, but to conserve always in its form and decoration the character of solidity which is proper.
- Jean Peronnet
Architects and engineers are among the most fortunate of men since they build their own monuments with public consent, public approval and often public money.
- John Prebble
Engineering is the art of modelling materials we do not wholly understand, into shapes we cannot precisely analyse so as to withstand forces we cannot properly assess, in such a way that the public has no reason to suspect the extent of our ignorance.
- Dr AR Dykes
Engineering problems are under-defined, there are many solutions, good, bad and indifferent. The art is to arrive at a good solution. This is a creative activity, involving imagination, intuition and deliberate choice.
- Ove Arup
Engineering refers to the practice of organizing the design and construction [and, I would add operation] of any artifice which transforms the physical world around us to meet some recognized need.
- GFC Rogers
Engineers … are not mere technicians and should not approve or lend their name to any project that does not promise to be beneficent to man and the advancement of civilization
- John Fowler
Engineers … are not superhuman. They make mistakes in their assumptions, in their calculations, in their conclusions. That they make mistakes is forgivable; that they catch them is imperative. Thus it is the essence of modern engineering not only to be able to check one’s own work but also to have one’s work checked and to be able to check the work of others.
- Henry Petroski
Experience serves not only to confirm theory, but differs from it without disturbing it, it leads to new truths which theory only has not been able to reach.
- Dalembert
From the laying out of a line of a tunnel to its final completion, the work may be either a series of experiments made at the expense of the proprietors of the project, or a series of judicious applications of the results of previous experience.
- HS Drinker
Go for civil engineering, because civil engineering is the branch of engineering which teaches you the most about managing people. Managing people is a skill which is very, very useful and applies almost regardless of what you do.
- Sir John Harvey Jones
He … insists that no mathematical formula, however exact it may appear to be, can be of greater accuracy than the assumptions on which it is based, and he draws the conclusion that experience still remains the great teacher and final judge.
- James Kip Finch
His father loved him dearly, but his work, that of a civil engineer, had left him with but little time for his family. Energetic, active, and always taken up with some responsible work, he did not spoil his children with excessive tenderness.

I am an old man now, and when I die and go to Heaven there are two matters on which I hope for enlightement. One is quantum electrodynamics and the other is the turbulent motion of fluids. And about the former I am rather more optimistic.

In practical work he can be ingenious with regard to modifying apparatus; he uses engineering rather than imagination.
- Head Teacher’s reference for a student applying to University
It takes an engineer to undertake the training of an engineer and not, as often happens, a theoretical engineer who is clever on a blackboard with mathematical formulae but useless as far as production is concerned.
- The Rev EB Evans
Let him not be grasping nor have his mind preoccupied with … receiving perquisites, but let him with dignity keep up his position by establishing a good reputation. No work can be rightly done without honesty and incorruptibility.
- Vitruvius
Men build bridges and throw railroads across deserts, and yet they contend successfully that the job of sewing on a button is beyond them. Accordingly, they don’t have to sew buttons.
- Heywood Broun
No greater care is required upon any works than upon such as are to withstand the action of water; for this reason, all parts of the work need to be done exactly according to the rules of the art which all workmen know, but few observe.
- Sextus Julius Frontinus
Nor aught availed him now
To have built in heaven high towers; nor did he scape
By all his engines, but was headlong sent
With his industrious crew to build in hell.
- John Milton
The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at and repair.
- Douglas Adams
There can be little doubt that in many ways the story of bridge building is the story of civilisation. By it we can readily measure an important part of a people’s progress.

Therefore O students study mathematics and do not build without foundations.

Urban myth at the Bar
Shallow slip failures on embankment and cutting slopes are more likely in certain geologies, particularly over-consolidated clays. The reinstatement of these shallow failures can be costly and the potential for slips may be reduced not only by the use of vegetation planted to provide reinforcement, through the plant root system, but also by a reduction in moisture content and pore water pressure. Report reviewing the potential for vegetation as a preventative measure in high-risk areas as well as investigating associated aspects such as the use of vegetation on reinforced steepened slopes in road widening and the use of live willow poles in reducing the risk of shallow failures.

Noboru Kikuchi "Finite Element Methods in Mechanics"
Cambridge University Press | English | 1995-06-30 | 436 pages | DJVU | 2,4 MB
This is a textbook written for mechanical engineering students at the first year graduate level. As such, it emphasizes the development of finite element methods used in applied mechanics. The book starts with fundamental formulations of heat conduction and linear elasticity and derives the weak form (i.e. the principle of virtual work in elasticity) from a boundary value problem that represents the mechanical behaviour of solids and fluids. Finite element approximations are then derived from this weak form. The book contains many useful exercises and the author appropriately provides the student with computer programs in both BASIC and FORTRAN for solving them. Furthermore, a workbook is available with additional computer listings, and also an accompanying disc that contains the BASIC programs for use on IBM-PC microcomputers and their compatibles. Thus the usefulness and versatility of this text is enhanced by the student's ability to practise problem solving on accessible microcomputers.

Author O'riordan, NJ,Seaman, JW Pages 80
Date 01/01/1994 Reference CR341
ISBN 0266-7045 ISSN 0266-7045
This report provides guidelines for the selection and design of the various techniques available for embankment construction on soft soils. Embankment construction is placed in an overall highway engineering context and the constraints experienced when building embankments in these conditions are then discussed. Site appraisal and design techniques are considered in order to determine which construction method is most suitable. A general review of each of the methods is made, including a discussion on their use, applicability and appropriate design methods. The requirements for additional soils information or instrumentation during construction has also been addressed. The use of the design procedures is illustrated using an hypothetical example.

The use of micropiles has grown significantly since their conception in the
1950s, and in particular since the mid-1980s. Micropiles have been used mainly as foundation support elements to resist static and seismic loads, and to a lesser extent, as in-situ reinforcements to provide stabilization of slopes and excavations. Many of these applications are for transportation structures. This manual is intended to be a “practitioner-oriented”document containing sufficient information on the geotechnical and structural design of micropiles for foundation support and for slope stabilization. Information is also provided on inspection and load testing procedures, cost data, and contracting methods to facilitate the safe and cost-effective use of micropiles on transportation projects. Two detailed design examples and a generic commentary guideline specification for micropiles is included in the manual.
