Latest report from Panama Canal organization
During the quarter ending June 2012, the locks design team discussed topics related to geotechnical engineering, and
instrumentation and control, such as the submittal of the final design for Borinquen Dams; monitoring of Gatun South
Plug; communications, instrumentation and control, and security and protection systems design; and fire extinction
systems for the new locks.
The materials assays lab under contract with ACP, Laboratorios Contecon Urbar Panamá S.A., continues to perform
validation assays and also does random assays as well as split sampling testing of all materials. No major quality issues
have been reported.
Hyundai has satisfactorily completed the factory-acceptance testing of 24 culvert valves. Manufacturing of other
five culvert valves, 13 conduit valves, and eight equalization valves continues. Additionally, the second-phase embeds
continue to be fabricated in Korea and the first embeds shipment arrived in Panama for installation.
In June, CH2M Hill met in Changzhou, Wujin, China with Bosch-Rexroth, Hyundai’s subcontractor for the fabrication of
the hydraulic cylinders. The visit focused on participating in the kick-off meeting for the fabrication of the cylinders; also,
an evaluation of the quality program and manufacturer’s processes was conducted.
On the Pacific site, GUPCSA continued setting up its temporary facilities. This contractor also finished assembling and
installing the water treatment clarifiers at the industrial park, as part of the washing system for the primary-aggregate
plant.
A prefabricated conveyor belt that connects the coarse sand stockpile to the rod mill is now in use to increase fine
sand production. Construction of an electro-mechanical shop to the southwest of the chilled water plant in platform B is
moving ahead.
Additionally, the contractor continues
performing maintenance on and fitting all
project hauling roads.
Massive volumes of material
excavated
The total cumulative excavation and dredging
volume reported for the Pacific site is
approximately 13.3 million m³. This material
was removed from the upper, middle and
lower lock chambers; lock heads; the middle
and lower water-saving basins; the north
approach channel; the dams and the wing
walls. The total cumulative overburden
material excavation volume is around 7.8
million m³. Total basalt material produced by
blasting is 2.8 million m³, removed from the
upper, middle and lower lock chambers; lock
heads; the water-saving basins; the Pacific
access channel, and the wing walls.
The cumulative dredging volume remains
Reclaiming land requires massive amounts of
material.
