Objectives It is anticipated that the following objectives will be met: Stage 1: Development of a Methodology It is proposed that this is developed along with the consultant who will then carry out the design assessment. The proposed methodology will aim to produce a document that can be used to assess all future assets. The details of the methodology are as follows: ; Identify the various types and groups of structures that are part of the ScottishPower network;; Identify assessment methods;; Produce a summary of asset attributes and ratings to be assessed;; Determine scoring system which will produce a condition rating to determine if the asset can be reused;; Set out Health and Safety assessments that will be used along with the condition assessments. ; Highlight acceptable risks. Stage 2: Design Assessment The outline scope will be as detailed below: ; Desktop assessment of the as-built records to determine the original design loadings;; Consider dynamic loadings and understand design loadings from old and new electrical infrastructure;; Determine where the weak points in the structures are and what proposed strengthening works could be undertaken to the existing structures;; Determine a condition assessment/testing strategy that is required to complete the assessment. Stage 3: Visual and Condition Assessment It is proposed that a visual and condition assessment will be carried out, with any specialist testing being undertaken by an approved contractor. It is expected that a combination of Non-Destructive and Intrusive testing will be required and that test samples will be sent to a UKAS accredited laboratory for evaluation. Stage 4: Report The final report will collate the data gained from project Stages 2 & 3 providing recommendations such as: ; Identify repair/reuse/strengthening works that need to undertake to increase the service life of the asset(s);; Repair specification for a contractor to provide an accurate cost and in turn carry out the necessary repair / improvement works;; Detail of the risk that ScottishPower will need to accept in order to continue using these existing assets, such as reduced factors of safety etc;; Cost benefit analysis of repair / reuse / strengthening works including ongoing inspection and maintenance requirements against the cost of replacement. It is expected that this project will be successful if the following outcomes can be returned: ; Increases the lifespan of existing structures by 20+ years;; Demonstrates notable savings in-line with the service life;; Reduced on-site working times and number of outages required.
Abstract There is a very large asset base of concrete structures within ScottishPower that are approaching or have potentially reached the end of their service life. Current practice within ScottishPower is to demolish these concrete structures and replace them with new steel structures. It has been identified that alternative methods are available that can possibly extend the lifespan of the existing structures. Where it is identified within the concept design that certain existing structures can be reused then ScottishPower want to investigate the viability of this. To realise the potential benefit of this, ScottishPower wants to review current practice and identify a methodology that is more sustainable, requires less outage time to construct and is more economical. The aim of this project is to create an assessment process and specification to determine whether these existing concrete assets are suitable for reuse. This project will develop a methodology to determine the assessment criteria, reuse, strengthening and repair process. The methodology will then be used to implement the recommendations from the design assessment which will be collated through the design reporting stage. This will allow recommendations to be implemented within each asset replacement programme to allow existing concrete assets to be re-furbished as appropriate. It is anticipated that this approach will allow ScottishPower and the wider industry to achieve cost and time savings on major construction projects which in turn will help reduce system charges and provide increased network resilience by reducing outage requirements. The reuse of these structures will also support ScottishPower’s sustainable development policy. It is anticipated that identified projects will be used to develop the assessment process and specification. This learning will then be implemented as business as usualNote : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
