The main thrust of the project will be the construction of new field level luxury suites, which could fetch the Eagles upwards of $200K per suite, per game. Dan Meis, who was one of the original designers of the Linc says that it's well positioned for an upgrade.
"Lincoln Financial has the advantage that there is ample available space [to build field-level suites], so it isn't particularly difficult and they would be highly valuable," Meis said.
The project may also include upgrading all jumbotrons and screens to latest HD technology and the construction of a free standing brewpub in the headhouse plaza. The team also mentions "other fan enhancements."
The project, which is estimated to cost between $60 and $100 million is only in the planning stages. When you combine this with the major solar energy installation that will make the Linc completely energy independent, it's clear that the Eagles are making some major investments in their building, but also the city in general.
