Description: We are working with 9 partners on a major new flood scheme for Oxford, which will reduce flood risk to homes, businesses, and major transport routes into the city. Our scheme will provide a long term solution to flooding in Oxford, helping protect the city as flood risk increases with climate change. The scheme will run through the existing floodplain west of Oxford. It will be formed of a new stream surrounded by a gently sloping floodplain of new wetland habitat and grazing meadow to create more space for water away from built-up areas.
DCA (RAG) Amber
DCA text: The Infrastructure Project Authority's Delivery Confidence Assessment rating is Amber.This is primarily due to the following factors: We have confidence in the delivery of Oxford Flood Alleviation Scheme with respect to the design, quality and ability to meet our current programme. The scheme is fully funded and we have confidence that this will remain to be the case for our Full Business Case. We are carefully managing and monitoring the risk that our programme could move due to external factors. We are working closely with Oxfordshire County Council to mitigate this risk.
Start date 2014-04-02
End date 2030-01-09
Schedule text The project end-date is 09 January 2030. This is primarily due to the following factors: Project delivery is within cost and programme forecasts.
Baseline £2.94m
Forecast £2.24m
Variance -24.00%
Variance text: The budget variance exceeds 5%. In the last financial year the scheme has undergone significant change brought about by external challenges that have led to re-design of certain elements of the scheme and withdrawal of our Compulsory Purchase Order and planning application. This has resulted in a longer programme, pushing out planning approval and construction completion. This has changed our expenditure needs, reducing contractor costs significantly, as well as consultants and our internal staff.
Whole Life Cost £204.83m
WLCost text: The projects Baseline Whole Life Cost is £204.83m. This is primarily due to the following factors: The whole life cost for the Oxford Flood Alleviation Scheme, considers all the work needed before, during and after scheme construction. This includes the cost of the work needed to design the scheme; gain the necessary planning approvals; purchase the required land and obtain business case approvals. It also considers the cost of materials and labour to construct the scheme, allowing for inflation and contingency for any risks which could occur and impact the delivery programme or cost. It also further includes the estimated cost of works needed to maintain the scheme over a 100 year period to ensure that it can operate at full capacity as a flood alleviation scheme and ensure benefit delivery.
