A landscaper works on the grounds of a children’s hospital earlier this month in Basra, Iraq’s second-largest city, 340 miles southeast of Baghdad. The 65 million hospital has yet to open because of problems connecting to the electricity grid. This site is among hundreds of projects funded by U.S. taxpayers that remain abandoned or incomplete, wasting more than billion, according to auditors.

Khan Bani Saad, Iraq ? A $40 million prison sits in the desert north of Baghdad, empty. A $165 million children’s hospital goes unused in the south. A $100 million waste water treatment system in Fallujah has cost three times more than projected, yet sewage still runs through the streets

As the U.S. draws down in Iraq, it is leaving behind hundreds of abandoned or incomplete projects. More than $5 billion in American taxpayer funds has been wasted — more than 10 percent of the roughly $50 billion the U.S. has spent on reconstruction in Iraq, according to audits from a U.S. watchdog agency.

That amount is likely an underestimate, based on an analysis of more than 300 reports by auditors with the special inspector general for Iraq reconstruction. And it does not take into account security costs, which have run almost 17 percent for some projects.

There are success stories. Hundreds of police stations, border forts and government buildings have been built, Iraqi security forces have improved after years of training, and a deep water port at the southern oil hub of Umm Qasr has been restored.

Even completed projects for the most part fell far short of original goals, according to an Associated Press review of hundreds of audits and investigations and visits to several sites. And the verdict is still out on whether the program reached its goal of generating Iraqi goodwill toward the United States instead of the insurgents.

Col. Jon Christensen, who took over as commander of the U.S. Army Corps of Engineers Gulf Region District this summer, said the federal agency has completed more than 4,800 projects and is rushing to finish 233 more. Some 595 projects have been terminated, mostly for security reasons.

Christensen acknowledged that mistakes have been made. But he said steps have been taken to fix them, and the success of the program will depend ultimately on the Iraqis — who have complained that they were not consulted on projects to start with.

“There’s only so much we could do,” Christensen said. “A lot of it comes down to them taking ownership of it.”

Troubled program

The reconstruction program in Iraq has been troubled since its birth shortly after the U.S.-led invasion in 2003. The U.S. was forced to scale back many projects as they spiked in cost, sometimes to more than double or triple initial projections.

As part of the so-called surge strategy, the military in 2007 shifted its focus to protecting Iraqis and winning their trust. American soldiers found themselves hiring contractors to paint schools, refurbish pools and oversee neighborhood water distribution centers. The $3.6 billion Commander’s Emergency Response Program provided military units with ready cash for projects, and paid for Sunni fighters who agreed to turn against al-Qaida in Iraq for a monthly salary.

But sometimes civilian and military reconstruction efforts were poorly coordinated and overlapped.

Iraqis can see one of the most egregious examples of waste as they drive north from Baghdad to Khan Bani Saad. A prison rises from the desert, complete with more than two dozen guard towers and surrounded by high concrete walls. But the only signs of life during a recent visit were a guard shack on the entry road and two farmers tending a nearby field.

In March 2004, the Corps of Engineers awarded a $40 million contract to global construction and engineering firm Parsons Corp. to design and build a prison for 3,600 inmates, along with educational and vocational facilities. Work was set to finish in November 2005.

But violence was escalating in the area, home to a volatile mix of Sunni and Shiite extremists. The project started six months late and continued to fall behind schedule, according to a report by the inspector general.

The U.S. government pulled the plug on Parsons in June 2006, citing “continued schedule slips and … massive cost overruns,” but later awarded three more contracts to other companies. Pasadena, Calif.-based Parsons said it did its best under difficult and violent circumstances.

Citing security concerns, the U.S. finally abandoned the project in June 2007 and handed over the unfinished facility to Iraq’s Justice Ministry. The ministry refused to “complete, occupy or provide security” for it, according to the report. More than $1.2 million in unused construction material also was abandoned because of fears of violence.

The inspector general recommended another use be found for the partially finished buildings inside the dusty compound. But three years later, piles of bricks and barbed wire lie around, and tumbleweed is growing in the caked sand.

“It will never hold a single Iraqi prisoner,” said inspector general Stuart Bowen, who has overseen the reconstruction effort since it started. “Forty million dollars wasted in the desert.”

Lack of coordination

Another problem was coordination with the Iraqis, who have complained they weren’t consulted and often ended up paying to complete unfinished facilities they didn’t want in the first place.

“Initially when we came in … we didn’t collaborate as much as we should have with the correct people and figure out what their needs were,” Christensen said. He stressed that Iraqis are now closely involved in all projects.

One clinic was handed over to local authorities without a staircase, said Shaymaa Mohammed Amin, the head of the Diyala provincial reconstruction and development committee.

“We were almost forced to take them,” she said during an interview at the heavily fortified local government building in the provincial capital of Baqouba. “Generally speaking, they were below our expectations. Huge funds were wasted, and they would not have been wasted if plans had been clear from the beginning.”

In some cases, Iraqi ministries have refused to take on the responsibility for U.S.-funded programs, forcing the Americans to leave abandoned buildings littering the landscape.
