47.(1) Quantities
The quantities set out in the Schedule of Quantities are the estimated quantities of the work and they are not to be taken as the actual and final quantities of the Works to be executed by the Contractor in fulfillment of his obligations under the Contract.
The Engineer shall ascertain and determine the value of the Works but, when required to do so by the Engineer, the Contractor shall measure the work executed during each month and the materials on Site and shall deliver to the Engineer a supporting statement with his monthly statement in terms of Clause 52(1), showing the said measurements and the relevant amounts paid or payable by him for such materials and all other particulars required by the Engineer.
(3) Engineers intention to measure
The Engineer shall, when he wishes to make any measurement on the Site or requires any parts of the Works to be measured in his presence, give notice of that fact and of the date and time at which he will be present to the Contractor who shall
(a) attend or send a qualified agent to assist the Engineer in making such measurement or to make such measurement in the presence of the Engineer, and
(b) furnish all particulars required by the Engineer.
(4) Contractors failure to comply
If the Contractor, despite being required to do so, fails
(a) to submit a supporting statement in terms of Sub-Clause (2), or
(b) to attend or send his agent when given such notice in terms of Sub-Clause (3), then the measurement made by the Engineer or approved by him shall be taken to be the correct measurement of the work for the purpose of the payment certificate in respect of which the measurement has been made.
The work shall be measured in accordance with the methods and procedures described in the Contract or, failing such description, in accordance with the methods and procedures applicable to the category of work concerned as set out in the standard methods of measurement laid down in the SABS 1200 Standardized Specifications current at the time of the tender.
48.(1) Provisional Sums
If any Provisional Sum is set out in the Schedule of Quantities and the
work to which
the Provisional Sum relates has been ordered by the Engineer and is
(a) executed by the Contractor, it shall be valued in accordance with the terms of Clause 40,
(b) executed by a Nominated Subcontractor, the Contractor shall be reimbursed the sum or sums paid by him to the Subcontractor, plus either(i) a commission on the sum or sums actually paid to the Subcontractor by the Contractor or the Employer, at the percentage stated by the Contractor in his tender, or failing such statement at 7,5 percent (seven and one half percent), or,
(ii) if the Contractor in his Tender has added to the Provisional Sum concerned a sum in respect of charges and profits, a pro rata amount of such sum, added in the proportion that the amount paid to the Subcontractor by the Contractor or the Employer bears to the Provisional Sum.
(2) Prime Cost Sums
Where a Prime Cost Sum is provided in the Schedule of Quantities to cover the cost price of certain goods, services or materials to be supplied under the Contract, the amount to be paid therefor to the Contractor shall be the actual price payable by him, in substitution for the Prime Cost Sum, together with any charge included by the Contractor in his Tender to allow for labour, profit, carriage, establishment and for other charges related to such goods, services or materials.
(3) Provisional/Prime Cost Sums and contingency allowance
Expenditure in connection with Provisional and Prime Cost Sums and under the contingency allowance (if any) shall be solely at the discretion and on the instruction of the Engineer. Any parts of the amounts provided in the Schedule of Quantities which are not expended shall not be included in the Contract Price.
The Contractor shall produce all invoices, vouchers and receipts in respect of payments made by him in connection with Provisional or Prime Cost items when he requires payment for these items.
49.(1) Tendered rates and prices
Except as provided in this Clause or elsewhere in the Contract, the rates and prices stated in the Tender shall be final and binding throughout the period of the Contract.
(2) Application of Contract Price Adjustment Factor

(3) Variation in cost of special materials
Price adjustments for variations in the costs of special materials specified in the Appendix shall be made in the manner set out in the Contract Price Adjustment Schedule.
(4) Subsequent changes in legislation
If at any time after 28 days before the closing date for tenders there occur changes to any Act of Parliament, Ordinance, Regulation or By-law of any local or other statutory authority which cause additional or reduced cost to the Contractor (other than in terms of Sub-Clauses (2) and (3)) arising from the execution of the Contract, such additional or reduced cost shall, after due consultation between the Employer and the Contractor, be determined by the Engineer and shall be added to or deducted from the Contract Price and the Engineer shall notify the Contractor accordingly, with a copy to the Employer.
50.(1) Adverse physical conditions and artificial obstructions
If during the execution of the Works the Contractor shall encounter adverse physical conditions (other than weather conditions a. the Site or the direct consequences of those particular weather conditions) or artificial obstructions, which conditions or obstructions could not have been reasonably foreseen by an experienced contractor at the time of submitting his tender, and the Contractor is of the opinion that additional work will be necessary which would not have been necessary if the particular physical conditions or artificial obstructions had not been encountered, he shall give notice to the Engineer in writing as soon as he becomes aware of the conditions aforesaid, stating
(a) the nature and extent of the physical conditions and artificial obstructions encountered, and
(b) the additional work which will be necessary by reason thereof.

(4) Contractors right to claim
If the Contractor has duly given the notice referred to in either Sub-Clauses (1) or (2), he shall be entitled, in respect of any delay or additional Cost, to make a claim in accordance with Clause 51, provided that the cost of all work done by the Contractor prior to giving the notice or notices in terms of Sub-Clauses (1) and (2) shall be deemed to be covered by the rates and prices referred to in Clause 3(4).
51.(1) Claims procedure

(3) Records of facts and circumstances
In order that the extent and validity of claims in terms of this Clause may be properly assessed when they are submitted, the following provisions shall apply:

of discounts to the Contractor and inclusive of General Sales Tax, or any tax imposed in
replacement thereof, and duties payable on such materials by the Contractor;

Provided that(a) if the Defects Liability Period is extended in terms of Clauses 54(4) or 56(2) or if at the expiration of the original Defects Liability Period there remains to be executed by the Contractor any works ordered during such period in terms of Clauses 30 and 56, the Employer shall be entitled to withhold payment until the completion of the work concerned of so much of the second half of the retention money as shall, in the opinion of the Engineer, represent the cost of such work;

(b) In the event of a Defects Liability Period being applicable to the Contract and of a guarantee having been accepted by the Employer, the guarantee shall be released and returned to the Bank by the Employer on the issue of the Certificate of completion against its replacement by a guarantee to be executed by a Bank in a form approved by the Employer for an amount equal to half the amount of the initial guarantee and valid for the Defects Liability Period.
(c) When the whole of the retention money to which a guarantee in terms of paragraph (a) or a replacement guarantee in terms of paragraph (b) applies, would, but for the guarantee, have become payable to the Contractor, the guarantee shall be released and returned to the Bank.
(7) Set-off and delayed payments
In respect of any amount payable to the Contractor in terms of the Contract,
(a) the Employer may deduct from such payment any amounts which he is entitled by law to set off against such payment and shall state in a notice accompanying the said payment the reasons for such deductions, and
(b) in the event of failure by the Employer to make the payment on its due date, he shall pay to the Contractor interest at the prime overdraft rate as certified by the Contractors bankers upon all overdue payments from the date on which the same should have been made, without limiting any other right which the Contractor may have by reason of such failure to make due payment.

When all contract work has been completed, all final measurements agreed or, failing agreement, determined by the Engineer and all defects remedied, the Engineer shall, at the end of the Defects Liability Period (if any), issue to the Employer and the Contractor a Final Payment Certificate, the amount of which shall be paid to the Contractor within 28 days of the date of such certificate, after which no further payments shall be due to the Contractor (save in respect of matters in dispute, in terms of Clause 61, and not yet resolved)
If, at the time of the preparation of the payment certificate following the issue of the Certificate or Certificates of Completion for the whole of the Works, it is found that the aggregate of
(a) all the variations made by the Engineer in terms of Clause 39,
(b) all additional payments allowed by the Engineer in terms of Clause 51, and
(c) the adjustment upon measurement of the estimated quantities set out in the Schedule of Quantities
results in an increase or decrease in the Contract Price, determined before adjustment in terms of this Clause, greater than 15 per cent of the Tender Sum, excluding any allowance for contingencies therein and excluding from both the said Contract Price and the Tender Sum all payments or allowances for
(i) variations in price in terms of Clause 49,

agreement, determined by the Engineer having regard to all relevant factors
affected by such increase or decrease, including any adjustments to the Preliminary
and General allowances already made.
