Abstract
Protecting critical parts of UK infrastructure resources from criminal or terrorist attack in the UK is an industrial sector which is rapidly expanding. In 2016 the UK Security sector grew by 17% and in the last five years, its turnover has doubled to £12.2 billion. There are 13 sectors of Critical National Infrastructure (CNI) that are included in the security sector, where there is a high regard for the protection of the assets within CNI. The National Infrastructure Delivery Plan, outlines details of £483 billion of investment in over 600 infrastructure projects and programmes in all sectors and spread across the UK, up to 2020-21 and beyond.
The development and successful certification of Loss Prevention Certification Board (LPCB) products, demonstrates their ability to resist physical attack for guaranteed periods of time. LPCB state that the failure rate on products submitted to them for testing is 95%, the development and testing of these new products has historically been undertaken using an iterative ‘by eye’ approach. Although this has clearly developed suitable products, the iterative approach of fabricate, test, improve, retest is inefficient and can be improved upon using digital techniques.
The aim of this thesis is to develop a new method in which to design and test new security products, so that the probability of new products passing an LPCB attack test is greatly increased through two key methods; The assimilation and interpretation of historic test data and the finite element analysis of proposed structures. This, in turn, leads to more highly engineered products that are quicker and more economical to design and develop.
A novel database that contains unique data related to the physical testing of the LPCB rated products has been proposed, created and implemented. This has shown that a saving of £10,000 could have benefitted the company on a single product with its implementation and an overall saving of £30,000 spread over a year with multiple product test regimes. This reduction in time and money spent testing individual products multiple times could also mean that the Company can have an increased capacity for the development of new products in a year. Equally a new digital workflow which is validated against a bespoke physical testing regime has been developed and implemented, which when combined with the database has led to reduced product development and increased efficiencies of product design.
This proposed methodology within the sector is unique and has generated interest from companies such as the Loss Prevention Certification Board. LPCB which is part of BRE Global, is commissioned by the BRE Trust, and wish to see the methodology rolled out across the sector.
