CHAPTER XVI

FOR BUILDERS AND CONTRACTORS

[Sidenote: The Builder’s Problems]

The rapid increase in population, and especially in its density, the

congestion in great cities, with the consequent building up of suburbs;

and the equally rapid upward tendency in the scale of comfort, are

factors of modern civilization which make the work of the builder and

contractor increasingly complex. The good builder is probably much

commoner than ever before, in spite of the popular impression that

building materials are poorer and that construction work is more often

“scamped” than they used to be. Increased transportation facilities make

the builder much less dependent on local and often inadequate materials.

And there has been a change in the theory and practice of government:

the old easy-going policy has been abandoned, and new laws, strictly

enforced, have resulted in such inspection and control of building

operations as would have seemed tyranny to the builder of a generation

ago and as make modern buildings, especially in cities, much safer than

ever before. Insurance companies have done much to the same end.

There is a general prejudice against the modern builder on the part of

the temperamental “praiser of the past.” Occasionally similar complaints

are made even against the builders of the past. Kipling sings:

Who shall doubt the secret hid

Under Cheops’ pyramid

Was that a contractor did

Cheops out of several millions?

Or that Joseph’s sudden rise

To Comptroller of Supplies

Was a fraud of monstrous size

On King Pharaoh’s swart civilians?

The mere duration of the pyramids, undamaged except by the hand of man,

is an answer to such a charge; and in the Britannica article PYRAMID the

reader will find (Vol. 22, p. 683) that even where the hidden material

was rubbly or of mud bricks, “the casings were not a mere veneer, but

were of massive blocks, usually greater in thickness than in height”—in

other words, that the construction was of the best character.

But the builder must be a far better-informed man under present

conditions than ever before. To give him the necessary information there

is a large and growing literature ranging from builders’ and

contractors’ pocket manuals to special periodicals. This literature is

expensive, and like all special literature puts the intending purchaser

in a difficult position, for _if he buys it all_, he must pay much more

than the returns from his purchase warrant, and he will then have to

_read it all_ and use his own judgment in deciding what is best. If he

does not buy all, he must be an expert, not merely in every branch of

his business but in the bibliography of his business, to make a wise

selection,—and if he is sufficiently expert for this he will probably

need no such library. But he will find, to a remarkable degree, the best

of all that there is in such special literature in the Encyclopaedia

Britannica, with the strongest assurance of its being authoritative, and

with the certainty that for an outlay, small in comparison with what he

would make for such special information elsewhere, he will get the

guidance that he needs for his work and also information as excellent on

any other subject that he or any member of his family may wish to

pursue.

The key or foundation article for the builder or contractor is BUILDING

(Vol. 4, p. 762), by James Bartlett, lecturer on construction, etc.,

King’s College, London, who has contributed other articles on related

topics. The article deals with:

The relation of building to architecture and with building laws and

special types of plans according to local governmental requirements

The conditions necessary for a successful building, namely—ease of

access, good light, good service, pleasing environment and approaches,

minimum cost with true economy, and, for office buildings, ease of

arrangement to suit tenants

Construction, its general principles
