The current construction climate in the UK is moving forward with a much greater attention on cost certainty, sustainability and adoption of innovative technologies. The UK Construction Strategy 2025 provides a clear direction towards achieving such goals by 2025. Life Cycle Costing (LCC) is one of successful techniques for identifying the total cost of ownership in construction assets. Even though the technique has 50 years of history, the application and the diffusion of the technique within the construction domain is comparatively limited. Therefore, this study aims to investigate the evolution and current status of LCC within construction context through Bibliometric Analysis of journal publications indexed in Web of Science database (1970-2020). A series of Contents Analyses was performed and visualisation maps were generated via VOSviewer. The findings proved that LCC has been absorbed into construction in late 90’s and there is a continuous rise in the global uptake from 2013 onwards. With limited budgets and growing demand for sustainability, an integrated methodology linking LCC, Life Cycle Assessment and Performance optimisation is apparently the way forward for LCC.

This paper presents a review of research in the area of life cycle costing and offers a critique of current commercial cost estimation systems. The focus of the review is on relevant academic research on life cycle cost from 2000 onwards. In addition to this a comparison of the current cost estimation systems is presented. Using the review findings and industrial investigations as a base, a set of mathematical representations for design and manufacturing costs and the introduction of the critical factors is proposed. These are considered in terms of the operational, maintenance and disposal costs to create a method for ascertaining the life cycle cost estimate for complex products. This is presented using as an exemplar, research currently being undertaken in the area of low volume and long life electronic products in the UK defence sector. The benefit of the method proposed is that it aims to avoid the inflexibility of traditional approaches which usually require historical and legacy data to support the cost estimation processes.

Purpose – The purpose of this paper is to establish the extent to which life cycle costing (LCC) is used as an early stage project evaluation tool by practitioners in the UK construction industry. The use of this evaluation tool has long been advocated by academics as a means of ensuring best value rather than lowest cost is a driver for business decisions related to potential built environment projects. Therefore there is a need to appraise its current uptake levels amongst built environment professionals and assess whether there are any barriers affecting its use in UK practice. Design/methodology/approach – Using a mixed methods approach, the authors present the findings from a survey of construction professionals located in the UK and the results from a series of follow up semi-structured interviews designed to further explore the factors found to affect the use of LCC in practice. Findings – The study shows that LCC is still not widely used by built environment professionals in the UK. The greatest inhibitor on the take up of the tool is the need of clients to budget on short-term horizons. Other factors such as a lack awareness of the tool by practitioners and clients, unreliability of data into the long term and the overriding need for commercially driven projects to achieve maximum return on investment continue to inhibit the widespread adoption of LCC as an early stage project evaluation tool. These findings have implications for the capability of the UK construction industry to deliver on its commitment to enhance the sustainability of the built environment. Originality/value – The paper offers insights into the current use of LCC and the factors affecting its use in the UK.

The Impact

The USAF’s R&M 2000 policy emphasizes the integration of reliability and maintainability considerations into a system’s preliminary design phase. This emphasis leads to unique requirements for turbine engines, including those of “wooden rounds” such as a HARPOON type missiles. In particular, it requires the development of tools for assessing the impact of design iterations on the reliability of “wooden round” weapon systems. Such tools must account for design iterations impact on storage, captive carry and launch reliability. A Markov approach is described in this paper, which provides an ability to track the reliability of a fleet of missiles/engines on a period by period basis, allowing one to assess when scheduled maintenance is appropriate and what components require such maintenance. Thus, inputs for Life Cycle Costing are generated, as well as the ability to determine tradeoffs between R&M and performance.

The development of electric delivery trucks has attracted much attention in recent years. The purpose of this study is to assess the greenhouse gas (GHG) emissions and the total cost of ownership (TCO) of light-duty and medium-duty diesel trucks (DTs), plug-in electric trucks (ETs), and battery-swap ETs. A simplified life cycle assessment (LCA) method and a TCO assessment method are used. Numerical results show that the average GHG emission of light-duty ETs is 69% lower than that of light-duty DTs, while that of medium-duty ETs is 9.8% higher than that of medium-duty DTs. As regards TCO, those of plug-in ETs and battery-swap ETs are 37.8% lower and 21% higher than that of light-duty DTs, while for medium-duty trucks, the TCO of plug-in and battery-swap ETs are 6.7% lower and 18.9% higher than that of medium-duty DTs. The main conclusion of this paper is that light-duty plug-in ETs exhibit the best performance in terms of cost saving and GHG emission reduction. Moreover, ETs show more advantages than DTs when the frequency of use is higher or when the driving environment is more congested.

In the U.K. full-authority digital controls are now being successfully demonstrated on military aero-engines following some years of practical research into suitable configurations for this class of power plant. For the case of Civil aero-engines the appropriate configuration of systems that will enter service from the mid-1980’s has been the subject of much debate between engine/airframe manufacturers and the principal accessory suppliers. This paper discusses the major features that will be embodied in these new systems, particular reference being made to: System tasks and performance requirements; configuration; life cycle costing; electronics design and system interfacing; and reliability and integrity.
