The latest estimate of Golden 1 Center’s construction costs have increased to $556.6 million.

Costs have increased by $21.7 million in just one month.

The $556.6 million price represents a more than $79 million increase since the Kings broke ground in October 2014 on what was envisioned as a $477 million project.

The original estimate when proposed in 2013 was $447 million, bringing the total increase to $109 million.

With the city’s subsidy capped at $255 million, all the additional costs are coming from the Kings.

The Kings have maintained that the increases aren't cost overruns as much as the costs of design changes implemented since the initial proposal.
