PITTSBURGH — Hilton Hotels & Resorts has pulled its name from a landmark Pittsburgh hotel.

A Hilton spokesman says the owner, Shubh Hotels Pittsburgh LLC, committed unspecified violations of its franchise agreement.

Shubh two weeks ago changed managers, hiring Dallas-based Prism Hotels and Resorts to jump start the hotel after financial and construction problems in recent years.

Workers walked off a $25 million renovation job in May 2009 after contractor P.J. Dick Inc. said Shubh stopped paying.

Shubh has been restructuring its finances and that work recently resumed.

The hotel has been a Hilton since it opened in 1959. With 700 rooms, it is the city's largest hotel.
