This department is charged with the maintenance of the operated
line and properties, and the construction of the relocated line for the
Isthmian Canal Commission. Until March, 1911, all engineering
work in connection with the Panama Railroad land department was
also handled by this department. On that date, the engineering
work in connection with land matters was turned over to the third

division of the Isthmian Canal Commission. ~

OFFICE ENGINEER WORK.

Office engineering work has been somewhat increased during the
resent fiscal year. The office consists of eight draftsmen and one
eae under the supervision of a chief draftsman. The force

has been engaged in routine work of mapping, designing, and pre-
paring monthly reports of the construction of the relocated line.
During the present fiscal year a new map of the relocated line between
Mindi and Gamboa, scale 400 feet to 1 inch, has been very nearly
completed. This map has been platted by latitude and departures
and when completed will show, in addition to the relocated line, all
of the old preliminary lines, with the topography. Maps and profiles
for the proposed Panama Government line to David, designing a
fireproof building, to be erected at the corner of Eleventh and Front
Streets, Colon, and the design for remodeling the steel pier at Balboa, |
have been completed. | :

Since January | a great deal of time and careful study has been
given to the preparation of plans for the permanent concrete docks at
Cristobal Point, and various types of construction were carefully
looked into and estimates of cost prepared.
