THE construction of the casino on Denarau, Nadi, will involve the excavation of mangrove land.
And solidifying the grounds on which the $290million casino will be built on is a high priority for the construction company tasked to build the gambling facility on.
Covering about 17 acres of land, the casino's construction began earlier this year by AATS Investments.
"We are in the process of doing some preloading of soil on to the land because it's quite moist and soft at the moment," AATS Investments director Riyaz Ali said.
"Preloading is basically putting soil on top of the soft soil so we can ensure that the foundation is strong enough.
"The preloading process will take about three months."
Mr Ali said construction of the actual facility would begin once the ground was secured.
The casino will be a single-level tall building located separately from a convention centre.
Resort rooms are also expected to be laid out towards a marina, which will be built simultaneously as the casino.
Construction work began in April following months of negotiations between government and the developers, One Hundred Sands Limited.
The company was awarded the exclusive licence to construct and manage the $290m casino, however, delays in construction work resulted in the company paying a fine of $185,000 per month to government from October last year.
