The staggering cost of rebuilding New York IT infrastructures continue to escalate, with estimates stretching from at least $3.2bn to a possible $7bn-plus.
Financial services research firm, TowerGroup, ballparks costs at about $3.2bn, to replace securities firms' technology destroyed in the World Trade Centre disaster.
Of the $3.2bn, $1.7bn will be spent on hardware; the other $1.5bn would cover software and services needed to install and connect the network, operating system and applications infrastructures, TowerGroup said.
Larry Tabb, Towergroup's vice president, securities and investments research, said: "We believe that 30,000 securities positions, trading, research and operations were destroyed in the seven World Trade Centre buildings."
He also estimated another 15,000 to 20,000 positions will need to be replaced in adjacent buildings such as the World Financial Centre and the Bankers Trust building.
A partial inventory includes 16,000 trading desks at approximately $52,000 each, and 34,000 general PC workstations at a replacement cost of $5000 each.
TowerGroup officials estimate that around 8000 Intel-based servers and about 5000 Unix servers were lost at an approximate replacement cost of another $370m.
It is anticipated that another $1.5bn is required to put the systems together.
Dell and Compaq, both of which have been favourites among Wall Street businesses, and have sent technicians to New York and Washington, have reportedly received large orders in recent days from securities firms and other companies which had occupied buildings in and around the trade centre.
One report said that within two days Dell had been called by all 85 of its New York clients directly affected by the attack, and was shipping 5000 computers.
