test erection of one of these towers in the vicinity of Albuquerque,
New Mexico, paid in dividends in the time saved in the final site
erection because of the supervision experience gained and the fact
that the contractor was able to properly match mark the various
structural members.
The construction work by the soldiers also progressed without
delay.
The island was divided into two sectors; one platoon assigned
the responsibility of construction within on particular sector.
One
of the most time-consuming activities was the paving and oiling of the
area around the Zero tower, even though an appreciable amount of
paving was eliminated by virtue of the fact that the hard compacted
airstrip surface falling within the area to be paved was oiled only.
This change, recommended by the JTF Engineer, was approved by the
Test Director and the Scientific Director on their visit to Engebi
on X5 February.
It was necessary to set-up rock crushing facilities on the
island in order to obtain properly graded aggregate.
A good borrow pit —
location was selected and material was crushed and screened, for use
in the concrete at Engebi and the other islands.
Concrete beams and
cylinders were made, the former tested in a field testing laboratory
which was set up by the OCE representative at Engebi, and the latter
shipped by air to the Honolulu District Engineer for correlation with
field test beams.
A tabulation of laboratory test was maintained by
the JIF Engineer and it was found that strengths attained greatly
