Appendix A WBTC No. 9/90 Appendix A Mathematical Derivation of Characteristic Factor (CF(T)) for Accepted Tender Number of tenders received p(i); i=p(t) p Standard deviation (())pipCharacteristic factor for accepted tender CF(T) ppt Appendix B Worked Example for Adjusting Uncharacteristically Low Tender Data Accepted tender price p(t) = $41.377 M p = $48.877 M = $3.301 M Characteristic factor of accepted tender CF(T) = ($48.877-$41.337)M $3.301 M = 2.284 (1) �CF(T) = 2.284 1.922 (Refer to Para. 2(4) of Circular) Therefore, it is an uncharacteristically low tender i.e. CF = 1.922 (2) Adjusted tender price (p) = Average tender price ( p - CF = $(48.877 - 1.922 = $42.533 M (3) Adjusted factor = Adjusted tender prices (p) Accepted tender price (p(t)) = $42.533 M/$41.337 M = 1.029 (4) Adjusted Cost of Works = Adjustment factor Cost of Works = Appendix C WBTC No. 9/90 Appendix C Worked Example for Adjusting Uncharacteristically High Tender Data Accepted tender price p(t) = $147.153 M p = $156.931 M = $18.594 M Characteristic factor of accepted tender CF(T) = ($156.931-$147.153)M $18.594 M = 0.526 (1) �CF(T) = 0.526 0.612 (Refer to Para. 2(5) of Circular) Therefore, it is an uncharacteristically high tender i.e. CF = 0.612 (2) Adjusted tender price (p) = Average tender price ( p - CF = $(156.931 - 0.612 = $145.522 M (3) Adjusted factor = Adjusted tender prices (p) Accepted tender price (p(t)) = $145.522 M/$147.153 M = 0.989 (4) Adjusted Cost of Works = Adjustment factor Cost of Works = Appendix D WBTC No. 9/90 Appendix D Standard Clause for Adjustment for Uncharacteristic Tenders Adjustment for Where the accepted tender for any part of the Works is considered uncharacteristically low or high in accordance with criteria given in Works Branch Technical Circular No. 9/90 "Adjustment of Consultants Remuneration for Uncharacteristic Tenders", the Cost, the Net Cost and the Adjusted Net Cost of that part of the Works as the remuneration to be paid under Clause ....... by the application of a percentage increase or decrease calculated by the method given in the above Works Branch Technical Circular. Any revisions or changes to Works Branch Technical Circular No. 9/90 shall not apply to this Agreement without agreement between the Director's Representative and the Consultants.
