Full-scale construction for Resorts World Las Vegas is expected to start in the last quarter of 2016, with plans for the casino resort to open on the Las Vegas Strip in 2019.

Developers of the resort was originally eyeing a 2018 opening for the $4 billion Chinese-themed resort, but Resorts World general counsel Gerald Gardner told the Nevada Gaming Control Board early this week that the opening date was pushed back for another year.

The executive was quoted by Vegas Inc saying the delay was due to the ongoing work on the casino resort’s “complex design” as well as the Malaysian currency, which has affected the timeline.

Gardner told the gaming control board to expect site activity to ramp up this summer, but major construction will get underway in the last three months of the year. The company expects to create some 5,000 direct construction jobs once the building activity is in full swing.
