3 BLACKPOOL BOROUGH COUNCIL STRATEGIC OUTLINE BUSINESS CASE FOR BLACKPOOL BRIDGES MAINTENANCE GROWTH FUND BID TO LANCASHIRE ENTERPRISE PARTNERSHIP SCOPING DOCUMENT INTRODUCTION AND PRINCIPLES This paper sets out the proposed scope of the Strategic Outline Business Case (SOBC) for intervention for Lancashire Enterprise Partnership (LEP) Growth Deal funding for the maintenance of Blackpool s ten strategic bridges and highway structures. These bridges provide key transport links both into and within Blackpool and their continued use is essential for the social and economic wellbeing of the town. The SOBC will set out the preferred way forward for the bridges and will present evidence for decisions to be made. The anticipated Growth Deal funding for the first phase of work to Blackpool s priority bridges is 4.23m. The project is defined by DfT as a small project (i.e. < 5.0m). A proportionate approach is therefore proposed to be adopted in the preparation of this business case. This is particularly appropriate given that there are ten bridges and structures being considered within this business case. A full rigorous assessments of all ten projects would be disproportionate and a more appropriate approach is proposed. Given that the nature of the proposed work is capitalised bridge maintenance (i.e. like for like ), the predicted do something outcomes will have no effect on highway network capacity or economic, social and environmental wellbeing other than to maintain the status quo. A comparison therefore has to be made of the effects that the do minimum option would have when compared to the existing conditions. It is anticipated that, for some of the ten bridges, the do minimum option would result in traffic restrictions such as weight/width restrictions or closure of the bridge to vehicular traffic with consequential detrimental effects on highway network capacity, and economic, social and environmental wellbeing. It is proposed therefore to discuss the do minimum and do something options for each bridge in outline. Where practicable and achievable, the economic impact and value for money of the scheme will be assessed in accordance with the WebTAG guidance. However, given that traffic modelling is not available for the Blackpool BC area, traffic count data will be utilised within the TUBA assessment. It is proposed to utilise the programme level TUBA assessment work previously undertaken by Jacobs (modified where appropriate) as a basis for economic assessment. Undertaking more rigorous assessments would be considered as disproportionate, costly and time-consuming. The previous work will be updated with recent traffic count data, revised traffic diversion routes and latest cost estimates.

4 Principles for agreement in advance of detailed assessment are therefore as follows: TUBA assessments to be undertaken on do minimum cases only where this requires implementation of permanent weight/width restrictions or closure of the bridge to vehicular traffic. Programme level TUBA assessment work previously undertaken by Jacobs UK Ltd to be utilised as a proportionate approach measure. Prioritisation of individual projects to be based on both quantitative assessment (where undertaken) and qualitative information (e.g. programming of work by Network Rail). TUBA, TEE, AMCB and PA tables to be generated collectively where possible (e.g. for works to bridges on Seasider s Way). PROPOSED FORMAT OF THE SOBC FOR BLACKPOOL BRIDGES MAINTENANCE It is proposed to develop and submit the proposal using the Strategic Outline Business Case Template (May 2014) previously provided by LEP. The scope of the proposed business case is as follows:

Standard approaches and assumptions as per webtag guidance, e.g.: 2010 base year 60 year return period Standard approaches and assumptions as per webtag guidance. Sensitivity testing against scheme cost (inflation, construction costs, professional fees etc.). webtag webtag 2.4 VfM Statement Using the Appraisal Summary Table (AST) (see section 2.5), please include a summary of the conclusions from the Summary of AST required.

10 Value for Money assessment. The statement should provide a concise summary of the proposed scheme s economic, environmental, social and public accounts impact. 2.5 Preliminary Appraisal Summary Table AST to be generated for each bridge. 3. FINANCIAL CASE: 3.1 Affordability Statement Please explain how the affordability of the proposed scheme has been assessed. Affordability Assessment Cost estimates by Wilde Consulting Engineers (WCE) based on current market rates with similar projects in NW. Cross check with SPONS etc. 3.2 Financial Costs Please provide details of the Whole Life Costs of the proposed scheme and a profile of the costs over the period shown. See Scheme Costs Guidance Profile required Whole Life Costs ( m) Year 2015/ / / /19 >2019 Profile 3.3 Financial Cost Allocation Please illustrate how the Whole Life Costs (WLC) will be allocated between the organisations involved in the delivery of the proposed scheme. Profile required Local Growth Fund (WLC m) Profile Private Sector (WLC m)

11 Also provide a cost profile of the costs allocated to each organisation over the period shown. Profile Profile Other Public Sector (WLC m) 3.4 Financial Risk Please provide details of any financial risks associated with the delivery of the proposed scheme. Explain how these have been assessed and quantified. Have funds been committed? Identify any known shortfall in funding and provide evidence of how this shortfall will be addressed. BBC contribution (Initial funding for inspections and assessments). Scheme delivery in strict priority order. Construction cost inflation. Unknown contingencies (mitigated through advance site investigation and materials testing) It is understood that the initial bid for funding Blackpool s Bridges Maintenance programme was for 4.23m and that this has been approved in principle by LEP subject to submission of a SOBC. Since the initial submission further inspection and in-situ materials testing has been undertaken and feasibility/options reporting commenced. At time of writing it is anticipated that the total cost of completing the bridge maintenance programme is approximately 8.5m (Total cost of schemes in table below is 8.5m). Affordability beyond 4.23m is still being considered by BBC. Further applications for grant funding from LEP/Dft are not ruled out. For the purposes of this SOBC, projects will be prioritised up to a value of 4.23m. Third party involvement from Network Rail. 3.5 Financial Risk Management Please provide details of any risk allowance or contingency built into the Whole Life Costs of the project.
