             According to Rule 2A of Service Tax (Determination of Value) Rules, 2006, subject to the provisions of section 67, the value of service portion in the execution of a works contract, referred to in clause (h) of section 66E of the Act, shall be determined in the following manner, namely:-
(a) Regular Scheme [Rule 2A(i)]
(b) Standard Deduction Scheme [Rule 2A(ii)]
So, if the service portion is seperately determined, ST  @  full charge or 15% with cess will be appliicable under Rule 2A(i)(here on Rs. 23,000/-)
Your liability under RCM would be 50% of the ST chargeable.
