Manasi,
Greetings .....
I do not know if any Insurance Company is offering an Insurance Policy under BOCW Act or if at all there is an Insurance Policy that could cover all risks as detailed in BOCW Act which looks into almost all aspects of Construction activity and made certain guidelines for "safe working" at construction sites. BOCW focuses more on "Construction Safety" and provides guidelines to avoid unwanted accidents at site. It even specifys guidelines for use of heavy construction machinaries. Also, it covers Payment of Cess on value of Construction Work,
As far as I know, only WC and ESIC covers the risks involved in construction activities.
