CLEVELAND, Ohio -- The Cleveland Cavaliers and owner Dan Gilbert will spend an extra $45 million for additional upgrades at Quicken Loans Arena, bringing the total price of the Q transformation project to $185 million.

The Cavs announced the injection of money and the additional improvements it will fund on Tuesday. The Cavs' total contribution will be at least $115 million by the time the transformation is expected to be complete in October 2019, as the Cavs committed to covering any cost overruns from the project.

Public funding will remain at $70 million, which will come from taxes on tickets for arena events and rooms at Cuyahoga County hotels.

The extra $45 million will cover several improvements that the Cavs identified during construction. The team wanted to complete the additional work now while construction is ongoing, according to Cavs CEO Len Komoroski and spokesman Tad Carper.

One of the improvements will be a total overhaul of the Cavs locker room, which officials say will be ready before the start of the 2018-2019 season.

Other improvements are related to extra upgrades for the audio/visual equipment, LED lighting, and multi-media improvements, Komoroski said.

Carper said that the project did not generate $45 million in cost overruns. Rather, the team opted to invest the extra money to improve upon the already-planned upgrades.

The original $140 million transformation plan was a 50/50 split between the Cavs and the public.

The public dollars were committed for re-designing a portion of the arena's public areas and expanding square footage to accommodate those improvements. The Cavs' portion covers all non-public, club, suite, team and premium spaces, as well as lighting and technology upgrades. The team is also covering a portion of the public space improvements, like changes to the concourse and an expanded building footprint.
