Arlington-based CACI International is being sued by a subcontractor who claims the company abruptly terminated its contract and began trying to hire its employees.

Eatontown, N.J.-based Engineering Solutions & Products said in a filing with the U.S. District Court for the Eastern District of Virginia that it became a contractor to CACI in 2006 on the Army’s strategic service sourcing — 0r S3 — contract vehicle.

ESP won the deal as a prime contractor — beating out CACI—in 2013, and CACI terminated the subcontract. The New Jersey company alleged the contractor breached their agreement, did not provide 10-day notice and began trying to hire ESP’s employees, according to court documents.

In its own filing, CACI contended ESP signed an exclusive arrangement with CACI — without which the defense contractor would not have given work to ESP.

The company alleged that ESP used its spot as CACI’s subcontractor to learn confidential information about CACI’s proposal for the contract, including its bidding strategy and pricing information, and used it to prepare its own bid.

Accenture Federal buys ASM Research

Arlington-based Accenture Federal Services last week said it has acquired Fairfax-based ASM Research to expand its work with the Pentagon and the Department of Veteran Affairs.

Under the deal — whose terms were not disclosed — ASM will become a wholly owned subsidiary of Accenture Federal.

The company said the buy will expand its work in federal health IT. Jim Traficant, managing director at Accenture Federal, will lead the new business. He previously headed Harris’s health care solutions business.

Paramount Business Jets comes to Loudoun

Paramount Business Jets , an air charter company, said it has established its headquarters in Loudoun, near Dulles Airport.

Richard Zaher, the company’s chief executive, is himself a local and Herndon High School graduate. He said he started the company in New York in 2005, but noticed in recent years an uptick in business in the Washington area.

Paramount doesn’t own or operate business jets, but has access to aircraft that it can hire for clients. The company pitches its transparent pricing; it shows clients its cut of the cost, which Zaher said is generally between 10 and 15 percent.

Zaher said the company is finding an interested set of customers, both among tourists and government and business executives.

“They really like the transparency,” he said. “They want to have accountability for everything they’re being charged for.”

Paramount has eight full-time employees and another two-dozen part-timers, according to Zaher.

Lockheed protest denied

The Government Accountability Office last week denied a protest filed by Bethesda-based Lockheed Martin against a contract awarded by the General Services Administration to L-3’s Reston unit.

Lockheed had argued that the agency’s technical evaluation and award decision on the contract, which covered IT services for an Army office, were improper. The GSA had received nine proposals, including L-3’s, which was priced at $362 million, and Lockheed’s, which came in just shy of $349 million.

“L-3’s technical advantages under the technical approach, key personnel and project staffing, and past performance evaluation factors outweighed Lockheed’s cost advantage,” the report said.
