3 REPEX model key requirements: Built on a bottom up approach to enable a better control and estimate of expenditure Model built on a dynamic structure which supports a number of degrees of freedom, such as: Overall group assets REPEX strategy adjustments Particular assets REPEX strategy changes Addition/removal of assets as required Dynamic adjustments to predictive /preventative & corrective expenditure to individual or assets groups Assess amounts of spent as a function of the maintenance strategy and its effect on the assets lifecycle Control assets life cycle/ expenditure and benchmark against past figures and other airports If successful, be the base for a risk based Asset Stewardship process. The REPEX model intends to estimate the annual and overall expenditure associated with maintenance & repair costs of the assets (including pavements) that make up a major airport investment
4 REPEX model key features: Comprehensive list of infrastructure assets/ subassets which represents the majority of infrastructure value Assessment of assets quantities Qualify each asset condition by assigning them an equivalent age. Equivalent age is the assets age, relative to its prescribed useful life, it would be expected the asset to have given its current condition Definition of preventive and corrective maintenance strategies and associated costs to each asset Calibration of the strategies to optimize the expenditure along the life of the concession with a view of providing enough residual life in the assets so as to meet the hand back conditions. Validation of the model against known REPEX expenditure of well maintained assets worldwide Assets groups for REPEX policy & strategies assignment: Asset Group 1: Passenger Terminals Asset Group 2: Airside Infrastructure Asset Group 3: Primary Utility Networks Asset Group 4: Equipment Asset Group 5: IT Systems Asset Group 6: Other Buildings

8 RWY panel being repaired RWY panel being repaired Shoulder widening A stretch of 2200m of RWY 10/28 are currently closed to operations. A number of pre-stressed pavement repairs are taking place together with 2x7.5 m shoulder widening project. The manholes closer to the runway are now being corrected/ reinforced (heights/ cover types)
9 Identify and quantify pavements differentiating the different pavements type of and year of construction Classify current pavements condition and with an equivalent age NO DETAILED ASSESMENT OR TESTING WAS POSSIBLE OR INTENDED AT THIS STAGE.
10 Identify and quantify different nature assets and sub assets types/ year of construction/ associated maintenance policy, etc. Subdivide assets in components. Classify current condition and attribute them an equivalent age

16 General Rules for REPEX Strategy/ Policy Definition and Costing Replacement periods and work intervals used in the models are based on published/ internal benchmark data (USD/m2/pa), feedback from buildings in use and our experience. Sensitivity analysis have been undertaken taking account of the impact on corrective and preventative asset maintenance procedures relative to the service life frequency and the percentage change in the lifecycle fund. This is particularly relevant for the M&E services and the specific in-use conditions of operation. The amounts included for Life Cycle Replacements take account of Main Asset and Sub-components only. They do not include for spare parts and consumables replaced as part of Frequent Maintenance. The life cycle costs have been calculated based on the following assumptions: All workmanships / installations / maintenances / operations / uses are in accordance with manufacturers' recommendations. Like-for-like performance replacement with best value for money solution Replacement periods assume that the appropriate planned maintenance is carried out in accordance with good industry practice and manufacturers' recommendations. Some assets are replaced at the end of foreseen obsolescence (i.e. IT systems). General lifecycle on-cost allowances: LC Management fee Design Fees FM Manage Fee LC Prelims Contractor s overhead and profit Strip Out Risk / Contingencies Exclusions: Inflation Taxes Capital Allowances Decant costs Condition surveys & inspections, structural and heritage surveys

18 REPEX Model
20 General Asset Info Strategy costing REPEX Strategy The above pictured templates were used to input the defined base case maintenance/ repair strategy into the model for each component.
21 Hand back asset life reflects the contractual obligation Discount factors are standard government economic discount rates Cost efficiency factors represent the general impact that reflects efficiency gains expected from a private entity running the airport
22 Passenger forecast numbers can be used to calculate REPEX/ PAX rates to benchmark the model s outcome against other airports Inflation can be considered within the model Strategies (1 & 2): the user can specify two periods where preventive spent deviates from the base case (e.g. -20% to + 20% to each asset ground). These changes on preventive spent affect the frequency of corrective maintenance interventions. The underlying relationship is being adjusted by the team of experts.
