set_value is refresh field automatically
you don’t need to add this refresh_field("grand_total");
And try to change the event to be onload

frappe.ui.form.on("Quotation","onload",function(frm, cdt, cdn){
    var d = locals[cdt][cdn];
    frappe.model.set_value(cdt, cdn, "grand_total", d.total+ d.erection_total_rs);
    });

That because there is another function override this action, you need to make your event on saving also to override it
you can use validate instead of refresh
