Excerpt from De Pontibus: A Pocket-Book for Bridge Engineers For a railway company, the most satisfactory method of building bridges is either to have a permanent, competent bridge engineer in its employ, or to retain some specialist of established reputation to prepare specifications and complete detailed plans (not working drawings, however) for all its bridges, and to provide competent inspectors to see that during manufacture, shipment, and erection the plans and specifications are strictly followed. The necessity for the specialist to stand between the pur chaser and the manufacturer of structural steel is, as a general rule, not appreciated by the purchaser, unless he has already had some experience in letting contracts for and in the building of steel structures without engineering aid in the designing and supervision. When the purchaser puts himself in the hands of the manufacturer, he is pretty sure to get the worst of it for if the contract be let by schedule prices the strue ture is liable to be loaded down with useless metal, while if the contract be let for a lump sum the structure will probably be ruined by having the metal skinned out of it, especially in the most important parts, v1z the details. Moreover. The manufacturer is seldom capable of evolving a truly first-class design, for the reason that his training has always been in the line of his own pecuniary interests, which are to obtain the maximum of pay for the minimum of structure so that, even when given all the metal and money that he could ask for when preparing a design, he would not succeed in making a really good one, simply because of not knowing how. On the other hand, the specialist should stand between the contractor and the purchaser, so as to see that the latter does not take any undue advantage of the former by means of a harsh or unjust interpretation of the specifications, especially when the contractor has suffered loss or delay on account of causes beyond his control.

Excerpt from Specifications for Steel Bridges: Taken From "De Pontibus" It appears that there is considerable demand by draftsmen and computers for the specifications of "De Pontibus," but that the book is too expensive to use for specifications only; consequently the author and publishers of that work have concluded to print the said specifications, together with the tables and diagrams, separately from the other chapters - hence this little book, which it is hoped will serve the purpose of the aforesaid gentlemen at one-third of the cost of the original treatise. A few changes in the specifications have been made in order to bring them up to date, the principal modifications being the following: 1st. The adoption of additional live loads in order to provide diagrams having engines as heavy as any yet built and even a little heavier. 2d. The increase in headroom for railway bridges from 21' 6" to 23' 0" . This is to provide safety for a tall man standing with his hands over his head on a car fifteen feet high. There are such cars in actual use; and several railroad companies are now specifying the greater clearance. 3d. The adoption of rollers surrounded with oil. This is a new detail now used in the author's practice. 4th. A modification of several formulæ for man-power apparatus in rotating draw-spans. The old formulæ required more metal than is really necessary. 5th. - Some slight changes in percentages of elongation on p. 108 (De Pontibus, p. 248).
