The board of the authority supervising construction of Metrorail to Loudoun County spent much of its time Wednesday talking about the funding of Phase 2 of the project and didn’t hear from staff on where things stand on the first part, which is now under construction. But we have an update.

The Metropolitan Washington Airports Authority (MWAA) is overseeing the 23 miles of new rail line that will stretch from Falls Church to Dulles International Airport and Loudoun County. The agency also operates Dulles and Reagan airports.

Here’s the status of Phase 1:

• The project is 65 percent complete as of October.

• 99 percent of the utility companies’ work is done. This had been a hefty expense for the project and used much of the $312 million in contingency funds. There is $71 million left in the contingency fund as of Oct. 30.

• The project is further behind. The completion date may now be Aug. 27, a couple weeks later than earlier estimates due to weather delays in September and October. Officials said they are still working out whether they can make up lost time. Once complete, the line has to be turned over for testing to Metro, which will operate and maintain the line.

Other interesting stats:

• 54.6 percent of the 753 workers on the job are Hispanic or Latino; 19.5 percent are African American, 21.5 percent are white and the rest are either Asian, Native American, Native Hawaiian or did not identify their race.

• The bulk of the workers come from Maryland (366); 328 come from Virginia and 33 from the District. The rest come from Georgia, Alabama, California, Delaware, Florida, Tennessee and West Virginia.

• $1.5 billion has been spent on Phase 1 of the Dulles project. It is expected to cost $2.8 billion.

The first phase — 11.5 miles that runs through Tysons Corner to Reston — is expected to be completed for riders in December 2013. There have been concerns that the first part of the project could be as much as $150 million over budget.

The stakeholders agreed last week on a deal to fund the second phase, and the airports authority approved it Wednesday. Loudoun County approved it Tuesday night, and Fairfax is expected to approve it in December. Phase 2 may go out for bid in April, officials said.
