SECTION 72

72.0 SUPPLEMENTARY SPECIFICATIONS FOR:

PART A: BUILDING WORKS AT WOODLANDS NEIGHBOURHOOD 7CONTRACT 34 (TOTAL : 194 DWELLING UNITS)

72.1 STEEL PRICE FLUCTUATION

72.1.1 General Requirement

The Contract Sum shall be adjusted by way of variation orders, addition

and/or omission, to reflect the fluctuations of the price of SteelReinforcement during the Steel Covered Period. For the avoidance of doubt, Steel Reinforcement shall be deemed to include both steelreinforcement bars and steel welded mesh reinforcement.

72.1.2 Quantity To Be Covered

The Covered Steel Quantity (hereinafter referred to as "CSQ" for thepurposes of this clause) of Steel Reinforcement to be covered for pricefluctuations shall be that stipulated in Part B of the Annex D of the FormOf Tender.

In the event that the source of any precast concrete components listed inAnnex F of the Form of Tender is obtained from the Employer, or wherethe Contractor’s production of precast components are carried out inoverseas precast plants, the quantity of steel reinforcement to be coveredfor price fluctuations shall be reduced according to the quantities indicatedin the same Annex F and the Contractor shall be notified within one (1)month from the date of the Letter of Acceptance.

The CSQ shall be deemed to be consumed for the Works in 18 equalmonthly parts during the Steel Covered Period of 18 months commencing

from the month following the commencement date of the Time forCompletion.

Notwithstanding the aforesaid and in the event that the project comprisesof at least one (1) building block of 35 storey and above, the CSQ shall bedeemed to be consumed for the Works in 22 equal monthly parts duringthe Steel Covered Period of 22 months commencing from the monthfollowing the commencement date of the Time for Completion.

72.1 STEEL PRICE FLUCTUATION (CONT’D)

72.1.2 Quantity To Be Covered (Cont’d)

To illustrate:

If the Commencement date of the Time for Completion is 31 Mar2007, then,

The Steel Covered Period shall be from Apr 2007 to Sep 2008(inclusive) for 18 months Steel Covered Period applicable to projectswith no building block of 35 storey and above.

72.1.3 Price Fluctuation Computation

The determination of price fluctuations for Steel Reinforcement shall

strictly be based on the "Monthly Material Price Indices ForImplementation Of Fluctuation Clause" produced by the Building andConstruction Authority (BCA). The period when the Price Index equals100 was J une 2006 and the Unit Cost of Steel Reinforcement was$757.00 per tonne.

The monthly adjustment for steel price fluctuation during the said SteelCovered Period shall be computed using the following formula:

[CSQ ÷SCP] x $757.00 x [(Current Index minus Base Index) ÷100]

Where:

CSQ = Covered Steel Quantity in tonnes

SCP = Steel Covered Period in months (Pleaserefer to sub-clause 72.1.2 above).

Current Index = BCA Monthly Material Price Index for SteelReinforcement for the relevant month of theSteel Covered Period.

Base Index = BCA Monthly Material Price Index for SteelReinforcement prevailing in the month of the latest date of Tender Closing. Toillustrate: if the latest date of TenderClosing is 1st Mar 2007, then the BaseIndex shall be based on the BCA MonthlyMaterial Price Index for SteelReinforcement for Mar 2007.

$757.00 = The price of Steel Reinforcement per tonne

when the BCA Monthly Material Price Indexfor Steel Reinforcement was 100

72.1 STEEL PRICE FLUCTUATION (CONT’D)

72.1.4 Other Considerations

(a) Where there is more than one commencement date for the Time for

Completion, the applicable date for determining the commencementof the Steel Covered Period shall be based on the earliestcommencement date of the various Time for Completion.

(b) Material price index for Steel Reinforcement shall be deemed toinclude both Steel Reinforcement and steel welded meshreinforcement.

(c) For each item of material which is subject to price fluctuation, onlyone Material Price Index shall be used regardless of the differentgrades or sizes of the material used.

(d) Only confirmed/final figures published by the BCA shall be used forcomputation of monthly adjustment for steel price fluctuation.

(e) The CSQ shall be fixed and no changes shall be effected for anychanges to the Works for whatever reason.

(f) The Steel Covered Period shall be fixed and no changes shall beeffected for any changes to the progress of work for whateverreason.

72.8.2 Reserved

72.8.3 Bonus And Discount For The Project

The bonus threshold score for this project is 88.7 points.

The discount threshold score for this project is 82.7 points.

The bonus and discount shall apply to the effective contract sum which is100% of the Contract Sum stated in the Letter of Acceptance.

A bonus/discount of 0.2% of the effective contract sum will be given foreach point scored above/below the bonus/discount threshold score. The

bonus/discount shall be subjected to a maximum of 3% of the effectivecontract sum or S$2 million whichever is lower. GST is not applicable forthe payment of bonus and deduction of discount amount.

The bonus shall be based on the CONQUAS score, and shall be payablein the Final Account and in accordance with the CONQUAS Certificate.

The discount, if any, will be deducted from the Final Account accordingly.

(a) Example 1

If a new project with an effective contract sum of S$100 millionachieved a CONQUAS score of 77.7 against the bonus thresholdscore of 75.5, the Contractor shall be rewarded the bonus amountof :

S$100M x 0.2 x (77.7 - 75.5) ÷100 = S$440,000

(b) Example 2

A project had a total contract sum of S$50 million. Sixty percent of the contract sum was estimated for the construction of 5 new blocksof 4-storey buildings. The remaining forty percent was for additionand alteration works to 2 existing buildings. If the project achieved aCONQUAS score of 78.0 against the bonus threshold score of 75.6,the Contractor shall be rewarded the bonus amount of :

S$50M x 60% x 0.2 x (78.0 - 75.6) ÷100 = S$144,000

(c) Example 3

A new project of S$100 million achieved a CONQUAS score of 67.5against the discount threshold score of 69.5, the discount applicable

shall be :S$100M x 0.2 x (69.5 - 67.5) ÷100 = S$400,000

72.8.4 Other Disincentives

For poor CONQUAS score, the relevant default points shall be recorded

against the Contractor under the Guidelines on the Default Points Systemwhich is administered by the BCA Contractor's Registry.

(a) Downgrading

The Contractor may be recommended for downgrading of financialcategories by one financial grade for up to a 12-month period if itaccumulates more than 5 CONQUAS default points in the latest fivecontracts completed within the last three years. Downgrading bymore than one financial grade will be considered on a case-by-casebasis, depending on the severity of the situation.



BSS S7272-25 of 72-37



72.8.4 Other Disincentives

(b) Price-Loading

BCA shall compile a list of contractors indicating the totalCONQUAS default points accumulated for the latest five contractscompleted within the last three years by each contractor. The listshall be given to the Employer on the first working day of eachmonth. This listing will be valid for every tender where the closingdate of the tender falls within that month.

A price-loading of 0.2% will be imposed for each CONQUAS defaultpoint. The applicable price-loading will be computed based on theproduct of the price-loading factor and the effective tender sum,subject to a maximum of S$2 million. The effective tender sum isthe portion of the tender which is subject to CONQUAS assessmentand is equal to the percentage indicated in the foregoing subclause"Bonus And Discount For The Project" for the application of thebonus and discount.

The Employer shall evaluate the tender based on the effectivetender value which takes into consideration the effective tendersum, price-loading as well as the portion of non-building work.Assuming all other things being equal, the contractor with the lowesteffective tender value will be awarded the project.

An example of computing penalty for Firm A who has completed 6projects is shown below :

ProjectName

Project 1 1 J anuary 1995 1

Project 2 1 J uly 1995 3


Project 4 1 J uly 1996 2


Project 6 1 August 1997 2

The penalty accumulated is 2 CONQUAS default points, calculatedfrom Project 2 onwards (most recent 5 projects) :

ie. (2+2+2) - (3+1) = 2.

In the above example, based on the effective tender value, Firm Cwill be awarded the project at his tendered sum of $301.3 million,

even though Firm A and B has tendered lower actual prices of $301million and $300 million respectively.

For joint ventures, the price-loading used to compute the effectivetender value shall be based on the highest default point among thepartners.

The price-loading is to be used for tender evaluation purposes only. The Contract Sum will be based on the actual tendered prices.
