Unacceptable for late night construction works

What is the rational of having constructions extended to 10pm in an area full of residential homes?

The construction of Rumah WIP Wangsa Meranti in Medan Idaman has gotten into controversy and criticism from residents nearby. The project, belongs to a consortium, rumored to be owned by a controversial figure (now in opposition).

Today, until very recently, the constructions were often extended past late night causing unwanted white noise pollution especially to condominiums nearby.
