The target date to begin the long-delayed renovation of Avery Fisher Hall is now 2019, and the New York Philharmonic is planning a campaign to raise its share of the construction costs and double its endowment, the orchestra disclosed in a recent job listing.

“The Philharmonic board recently resolved to undertake a major and historic campaign to raise funds for both the endowment and the planned renovation of Avery Fisher Hall to commence in 2019,” according to an advertisement seeking applicants for a new vice president position at the Philharmonic that was recently posted on industry websites.

“While the campaign’s stated goal will not be released publicly for some time,” the job listing continued, “the desired result is to effectively double the size of the endowment and to fund the Philharmonic’s estimated share of the building renovation planned with Lincoln Center.”

The 2019 date to begin the renovation of Avery Fisher is preliminary, officials at the Philharmonic and Lincoln Center said on Monday. They said they were using that time frame for planning purposes, and that much work remained before a date could be set.
