~ clay in the filing of steel orders
- is responsible for the slow progress
in the erection of the Security
,ank building, for which a deep hole
las been prepared at Second avenue S
md Fourth street. Twenty or more car
Dads of steel are at the works of the
Minneapolis Steel & Machinery company
or milling, and loads of etrra Gotta, to
he regret of the builders, have arrived,
which cannot be used until the steel
york is being placed. Should the iron
olumns which form the basis Of the
teel frame structure for the ten-story
'uilding arrive, progress would be
quickly apparent.
The fact is that the steel mills in the
asst will not stop rolling beams to roll
olumns, nor the reverse. AS it hap
lens now, they are rolling beams and
hey will continue to roll beams until
hey get thru. The orders are far
head of the mills and consequently the
Iecurity bank building in Minneapolis
uffers delay; for the mills are rolling
Minneapolis.
Altho the progress is not apparent,
he most delicate work in the construc-
ion of the building is being done.
hat is the foundation work. Forty
light steel and reinforced concrete
ootings are being placed in the bottom
f the foundation hole and If any Of
hem should vary fraction Of an inch
he whole building would be thrown out
plumb. For that reason the survey
RS are very carefully making their
e doubly sure. The sand is cleared
way for the footing and the stakes
ned up carefully with surveyors in
truments, for when the steelwork for
he tenth story is being placed it must
OF vary a fraction of an inch from
he plumb.
How It Goes Up.
Thirty-four inches of concrete, rein
breed with steel rods and bands, forms
he basis for the huge castiron plates
Dotted. After the plates are set on
he twelve-foot square concrete bases
he whole Is covered with concrete to
rotect against rust and fire. In fact,
be concrete protection plan is to be
sed in the entire building and every
it Of the steel skeleton is to be COW
red with concrete. Seventy sacks are
each of the footings, and in the en-,
Ire structure the enormous amount OF
5000 barrels of cement will be used.
he footings are put down at about the
LIGHT have been set The columns are
. be so distributed that no footing will
AIRY more than 31a tons to the square
DOT.
Piling was unnecessary in preparing
ae Security building foundations. The
I'm sand furnished a solid basis for
le beginnings. Engineering Difficult,
les will be rare, therefore, in the
@rection Of the big structure. One
eature is the necessity Of snoring up
small brick building on the south
age of the Deering property. To place
ne footings on this side it will be
ecessary to excavate in such a way
