it's as simple as
construct (arg1: type1, arg2: type2, arg3: type3)
    super(arg1, arg2, arg3)

BUT this won't work if the base class isn't defined in vala, in which
case you'll need to find the properties initialized by the creation
method (usually the same as the arg name) and chain up to GLib.Object
directly, something like (untested) :

construct (arg1: type1, arg2: type2, arg3: type3)
    Object(arg1: arg1, arg2: arg2, arg3: arg3)
