Cuban Facilities Needed In Global Terrorism
Fight
Pittsburgh-based Dick Corp. has signed a $13.5-million U.S.
Navy design-build contract to build a new two-story, 3,500-sq-m
building in Guantanamo Bay, Cuba, that includes suspected
terrorist detention and interrogation facilities.
The structure will be located on a secure site and work is
scheduled for December 2004 completion. The Navy has an option
toaward a $4.2-million design-build contract for a courtroom
with linked facilities. Architectural and engineering design
is being performed by Michael Baker Corp., Moon Township,
Pa.
For legal and political reasons, Dick must ship all equipment
and materials from Florida and hire third-country nationals
for site work. Dick must be self-sufficient and not rely on
nearby Cuban resources. Construction is scheduled to start
in January.
Wastewater Treatment Job Completed in
Chile
One of Latin Americas largest wastewater treatment
plants has been completed under a $220-million design-build
contract. The late October inauguration of the Farfana works
in Santiago, Chile, means some 3.7 million people, or half
the citys population, will now have their wastewater
treated for the first time.
The 8.8-cu-m-per-sec unit, located near the Mapocho River,
was completed within budget and "a month in advance compared
to contractual requirements," says Bernard Neguelouart,
who runs the Chilean office of Frances Degrémont
S.A., the turnkey builder. Degrémont started commissioning
last May and contractually is required to operate the plant
for a year, he says.
Degrémont designed and managed installation of all
the plant's equipment, which was largely sourced in Europe.
Its local subcontractors dealt with civil and other site work.
Degrémont is owned by the Paris-based Suez Group,
which has a major stake in Aguas Andinas S.A., Santiagos
partly privatized water and wastewater utility. But the firm
still had to bid against international rivals for the contract.
Degrémont won the contract in March 2001 and began
construction that November.
The Farfana plant, which includes biological treatment, is
a major element of Santiagos estimated $1.8-billion
water infrastructure improvement plan, scheduled for completion
in 2009.
Cable-Stayed Bridge To Span Orinoco
River
Work has begun on the first pylon of a $480-million design-build
contract for the 3.1-km rail and road crossing of Venezuelas
Orinoco River. With the substructure of the rivers second
crossing virtually complete, the design-build team aims to
start erecting a composite deck next May. The team will use
locally assembled elements fabricated in Minas Gerais, Brazil.
To
speed construction, the design-build team led by Brazil-based
Construtora Norberto Odebrecht substantially changed an initial
government agency plan, according to the contractors
project manager, Estevão Timponi. Odebrecht won the
contract, which also includes 166 km of linked highways, in
June 2000.
Over one-third of the Orinoco crossing will be cable stayed,
providing two 300-m navigation spans. Their two 120-m-long
stayed anchor spans will abut at a common support of two inclined
piers forming an inverted V. "That was the most efficient
way to transmit the high stresses to the foundations,"
explains Timponi.
For its design, Odebrecht hired the BRAVE consortium, led
by Brazils Figueiredo Ferraz Consultoria e Engenharia
de Projeto Ltd., and supported by German cable-stay specialist
Leonhardt, Andra und Partner. Their final design is different
from that of locally based Lustgarten Ingenieros Asociados,
prepared for the governments project agency, Corporación
Venezolana de Guayana. Instead of being reinforced concrete
on prefabricated beams, the cable-stayed deck is a composite
with a central 5.7-m-wide by 5.5-m-deep steel box girder connected
with steel edge beams via a series of outriggers. Also, at
60 m, approach spans are 50% longer than initially planned.
Odebrecht subcontracted about 24,500 tons of steelwork supply
and erection to Brazils Usiminas Mecanica S.A. Frances
Freyssinet International S.A. will supply bearings and cable
stays.
The project started in 2001 and is scheduled for a 2005 completion.
It will connect Ciudad Guayana with the northern portion of
the country and help develop Venezuelas eastern region.
