4 [Extract] Specification of Service Level Criteria for Paved Roads This section specifies the Service Levels to be complied with in the case of paved roads. There are four overall criteria: Road Usability Road User Service and Comfort Measures Durability Performance Measures Management Performance Usability of the Road The CE will have to ensure that the road is open to traffic and free of interruptions at all times. Interruptions are defined as any obstruction on the road causing disruption of traffic. Transitability of the whole road must be maintained during the construction activities. This includes the necessary activities to keep the road opened to traffic in three different fronts: Bridges to be replaced: passage will be maintained either across the current temporary bridge during the construction of the new one, when the location of the new one allows to keep the temporary bridge in service, or by constructing a temporary passage across the stream, over its bed. New construction links: During the construction a service road with a laterite surface or diversion / service roads will be made available, in order to keep an open passage for traffic. Rehabilitation links: During the rehabilitation works on the road, the traffic must be accommodated either within the existing carriageway or by constructing short bypasses around the construction fronts. In addition, transitability of the whole road must be maintained during maintenances stage. This includes all the activities required by the service level criteria. Appendix A 4

21 [Extract] Specification of Service Level Criteria for Paved Roads Determination of Payment Reductions The results of each formal inspection of the Service Levels and other performance criteria will be recorded by the Project Manager in the form of a Memorandum. The Memorandum will state the type and location of any non-compliance detected, in particular those non-compliances already shown in the standard tables provided by the CE as part of their monthly statement. For each individual case of non-compliance, the Project Manager (PM) will determine a date by which CE must have completed the necessary measures in order to remedy the cause of the non-compliance. A follow-up site visit is therefore necessary at the date fixed by the PM, or soon thereafter, in order to verify that the CE has remedied the cause of non-compliance. If at the date indicated in the Memorandum, the CE has not remedied the cause for noncompliance, independent of the reason given for their failure to do so, the CE is subject to Payment Reductions in accordance with the relevant clauses of the GC. Payment Reductions are variable over time. If the CE fails to remedy a cause of noncompliance for which a payment reduction has already been applied, the amount of the payment reduction increases month by month for that particular cause of non-compliance, without a ceiling being applied, until compliance is established. The calculation of the initial (first month) amounts of payment reductions, and the formula for their adjustment over time, is to be based on the following rules: For paved roads, there are three types of Payment Reductions: (i) Payment Reductions for non-compliance with Road User Service Comfort Measures: For any road or road section as specified in Section II of this document (Bid Data Sheet), the Employer may reduce the monthly lump-sum payment by the percentage of non complying kilometers as determined by the Project Manager each month. [Clause 2.1.1]. The payment will therefore be the basic lump-sum multiplied by the ratio of length of complying road to the total length of the network. (ii) Payment Reductions for non-compliance with road roughness criteria: Calculated based on the provisions shown in section 2.4 of Part A3: Level of service. The amount of the reduction is to be deducted by the Employer from the monthly lump-sum payments due to CE. (ii) Payment Reductions for non-compliance with pavement deflection criteria: In case of non-compliance, the payment reductions are equivalent to the amount needed by the Employer to have the works carried out which are necessary to establish the conditions of compliance which the CE should have complied with according to the contract. However, the maximum amount of payment reduction applicable by the Employer for non-compliance with Service Level criteria on pavement deflection is equivalent to the performance guarantee provided by the CE for the entire contract. For payment reductions there are three stages to influence and condition the contractor. The first stage consists on the application of the payment reductions for non compliance of level of service required. Those reductions are applicable during the first 30 days of non compliance after official notification. If the non compliance has not been remedied or repair within the first thirty days, a second stage is presented where another thirty (30) days may be given to the CE as grace period to repair the no compliances after official notification and deduction of payments will be calculates using the formula mentioned before. Appendix B 4

22 If the non compliance has not been remedied or repair within the first sixty (60) days after notification, the third and last stage will be applied providing the Employer with the option of sub-contracting another company to remedy all the non compliance that the CE did not repair. It should be noticed that if this stage is reached, the Contracting Entity will be fully responsible for all works and repairs done by the sub-contractor and the Employer will pay to the subcontractor deducting the amount from the payments to be done to the CE. In addition, from the day 61 after notification to the date of Compliance of Service levels by the CE, the non-compliance formula presented before will be applied. For paved roads: The following table applies: Appendix B 5
