City of Stirling Buildings Asset Managment Plan 2018 - 2028

5.3 Renewal/replacement plan Renewal and replacement expenditure is major work which does not increase the asset’s design capacity but restores, rehabilitates, replaces or renews an existing asset to its original service potential. Work over and above restoring an asset to original service potential is upgrade/expansion or new works expenditure, resulting in additional future operations and maintenance costs.

5.3.1 Renewal plan Renewal is undertaken using ‘low-cost’ renewal methods where practical. The aim of ‘low-cost’ renewals is to restore the service potential or future economic benefits of the asset by renewing the assets at a cost less than replacement cost.

Building assets or their components requiring renewal are identified from condition assessments, requests or proposals from building Service Managers, and also the investigation of customer requests. Building asset condition assessments form the basis of the renewal expenditure forecasts within this Plan.

The useful lives of assets used to develop projected asset renewal expenditures are shown in Table 5.3.1.
