• A Decision Support Tool for the Valuation of Variations on Civil Engineering Projects

      Sutrisna, Monty; Buckley, Kevan; Potts, Keith F.; Proverbs, David G. (RICS (Royal Institute of Chartered Surveyors), 2005)
      The valuation of variations has been recognised as a prime cause of conflict and dispute in construction management. Such disputes often concern the prices and/or rates to be applied to the varied works. Previous research has identified the subjectivity of the decision-maker in interpreting the valuation rules to be the major problem, particularly with regard to defining the work conditions and/or characteristics during a variation event. Findings of a survey, conducted to elicit the views and perceptions of experienced practitioners towards interpreting the valuation rules are presented. The development of a decision-making tool based on a robust framework for valuing variations in civil engineering projects is described. The tool was developed by analysing changes in various decision attributes. The result of the changes was then mapped to relevant sets developed using fuzzy-logic principles. Various operators were used to perform the fuzzy-aggregation operation. The modelling technique was demonstrated to be reliable in replicating the decision-making process performed by experienced practitioners. As such is considered a suitable aid for decision-making involved in valuing variations on civil engineering works. The results of the analysis reported here have suggested the fuzzy-logic as an appropriate tool to model human decision-making, particularly in valuing variations on civil engineering works. This is considered an essential progress of the current study in modelling human decision-making process, particularly since there are so many unknown aspects associated with such a process. The modelling technique successfully developed here is then used as the main algorithm for decision-making in the subsequently developed Knowledge Based System (KBS) which is intended to assist practitioners minimise conflict and dispute arising from the valuation of variations.
    • Achieving Best Value in Private Finance Initiative Project Procurement

      Akintoye, Akintola; Hardcastle, Cliff; Beck, Matthias; Chinyio, Ezekiel A.; Asenova, Darinka (Routledge (Taylor & Francis), 2003)
      The wherewithal of achieving best value in private finance initiative (PFI) projects and the associated problems therein are documented. In the UK, PFI has offered a solution to the problem of securing necessary investment at a time of severe public expenditure restraint. In PFI schemes, the public sector clients must secure value for money, while the private sector service providers must genuinely assume responsibility for project risks. A broad-based investigation into PFI risk management informs the discussion in this paper. It is based on 68 interviews with PFI participants and a case study of eight PFI projects. The research participants comprised of contractors, financial institutions, public sector clients, consultants and facilities management organizations. The qualitative software Atlas.ti was used to analyse the textual data generated. The analysis showed that the achievement of best value requirements through PFI should hinge on: detailed risk analysis and appropriate risk allocation, drive for faster project completion, curtailment in project cost escalation, encouragement of innovation in project development, and maintenance cost being adequately accounted for. Factors that continue to challenge the achievement of best value are: high cost of the PFI procurement process, lengthy and complex negotiations, difficulty in specifying the quality of service, pricing of facility management services, potential conflicts of interests among those involved in the procurement, and the public sector clients' inability to manage consultants.

    • BIM for deconstruction: an interpretive structural model of factors influencing implementation

      Obi, Lovelin; Awuzie, Bankole; Obi, Chukwudi; Omotayo, Temitope S; Oke, Adekunle; Osobajo, Oluyomi (MDPI, 2021-05-25)
      Transitioning from demolition to deconstruction practices for end-of-life performances is gaining increasing attention following the need for the construction industry to minimise construction and demolition waste. Building information modelling (BIM) presents an opportunity for sustainable deconstruction. However, the notion of BIM for deconstruction (BIMfD) is still in its infancy in the United Kingdom. Although a few studies on BIMfD are evident, a focus on identifying the underlying factors necessary for successful implementation of BIMfD is lacking. The purpose of this study was to identify and analyse the underlying factors necessary for BIMfD implementation in the UK construction industry. It employed a four-stage research design. The reviewed literature explored extant views on BIM implementation factors to identify an initial list of possible factors influencing BIMfD implementation. Subsequently, a mix of questionnaire, focus group discussions and structured interviews were employed at various stages to refine and contextualise 15 factors necessary for BIMfD implementation in the UK construction industry. The contextual interrelationships among the factors were evaluated using interpretive structured modelling (ISM). This evaluation culminated in a BIMfD implementation factor model. The findings identified BIMfD experts, responsiveness of business models to innovative practices and industry’s acceptance to embrace change as the principal factors influencing BIMfD implementation in the UK. The implications of the findings attest that BIMfD experts and advisors must champion the adoption and implementation of BIMfD in the UK and business models need to become more responsive to accommodate BIMfD innovative practices. A BIMfD framework was conceptualised. Even though the BIMfD framework was designed from the UK perspective, the global construction industry can leverage the outcomes of this study. This paper, therefore, brings to the fore, a hierarchical BIMfD implementation factor model to support improved deconstruction practices in the construction industry.
    • Effects of Palm-mat Geotextiles on the Conservation of Loamy Sand Soils in East Shropshire, UK

      Bhattacharyya, Ranjan; Davies, Kathleen; Fullen, Michael A.; Booth, Colin A. (Catena Verlag, Reiskirchen, Germany, 2008)
      Some 30% of world arable land has become unproductive, largely due to soil erosion. Considerable efforts have been devoted to studying and controlling water erosion. However, there remains the need for efficient, environmentallyfriendly and economically-viable options. An innovative approach has used geotextiles constructed from Borassus aethiopum (Black Rhun Palm of West Africa) leaves to decrease soil erosion. The effectiveness of employing palmmats to reduce soil erosion have been investigated by measuring runoff, soil loss and soil splash on humid temperate soils. Twelve experimental soil plots (each measuring 1.0 x 1.0 m) were established at Hilton, east Shropshire, UK, to study the effects of geotextiles on splash erosion (six plots completely covered with Borassus mats and six non-protected bare soil plots). Soil splash was measured (10/06/02-09/02/04; total precipitation = 1038 mm) by collecting splashed particles in a centrally positioned trap in each plot. An additional field study (25/03/02-10/05/04; total precipitation = 1320 mm) of eight experimental runoff plots (10 x 1 m on a 15o slope) were used at the same site, with duplicate treatments: (i) bare soil; (ii) grassed, (iii) bare soil with 1 m palm-mat buffer zones at the lower end of the plots and (iv) completely covered with palm-mats. Runoff volume and sediment yield were measured after each substantial storm. Results indicate that total splash erosion in bare plots was 34.2 g m-2 and mean splash height was 20.5 cm. The use of Borassus mats on bare soil significantly (P<0.05) reduced soil splash height by ~31% and splash erosion by ~50%. Total runoff from bare plots was 3.58 L m-2 and total sediment yield was 8.58 g m-2. Thus, application of geotextiles as 1 m protective buffer strips on bare soil reduced runoff by ~36% and soil erosion by ~57%. Although total soil loss from the completely covered geotextile plots was ~16% less than the buffer zone plots, total runoff volume from the completely covered plots was ~94% more than the buffer zone plots. Thus, palm-mat (buffer strips) cover on vulnerable segments of the landscape is highly effective for soil and water conservation on temperate loamy sand soils.
    • Factors relating to soil fertility and species diversity in both semi-natural and created meadows in the West Midlands of England

      McCrea, Alison R.; Trueman, Ian C.; Fullen, Michael A. (Blackwell, 2004)
      The post-war decline in the area and diversity of neutral meadows in Britain, resulting from agricultural intensification, has prompted schemes to restore and create new habitats. Their success relies on understanding the relations between soil fertility and species diversity. We have investigated these relations, using multivariate analysis, in 28 semi-natural meadows and eight artificially created urban meadows. Mineralizable nitrogen was the most important soil characteristic in the semi-natural sites; the more N the soil contained the fewer were the species characteristic of traditional meadows. Both potassium and total magnesium favoured diversity, perhaps because their deficiency in many traditionally managed meadows jeopardizes the survival of broad-leaved species in competition with grasses. Available lead, at sub-lethal concentrations and measured as a Pb:Ca ratio, appeared to favour diversity in the semi-natural sites, possibly by inhibiting the uptake of P by competitive grasses and allowing the less competitive species associated with diversity to flourish. The main differences between the soils of the artificial and the semi-natural meadows were that the former contained more extractable P and less mineralizable N and organic matter. It seems that large soil phosphorus concentrations may be the main reason why relatively few species colonize or survive in grassland on many urban soils.
    • Field studies of the effects of jute geotextiles on runoff and erosion in Shropshire, UK

      Mitchell, David J.; Barton, A.P.; Fullen, Michael A.; Hocking, Trevor J.; Zhi, Wu Bo; Zheng, Yi (Wiley InterScience, 2003)
      Jute geotextiles are widely used to stabilize steep banks and road cuttings. Jute protects bare surfaces until seeded grass becomes established, then after several years, the jute decays. To evaluate two types of jute geotextiles, eight erosion plots were established in July 1994 at the Hilton Experimental Site, Shropshire, UK. On 10 April 1995, the plots were treated as follows: (1) jute geotextile net; (2) jute mat; (3) perennial rye grass (Lolium perenne); and (4) bare soil, with duplicates of each treatment. Over one year, sediment yields from jute net and jute mat were 1.1% and 1.2%, respectively, of the yield from the bare control. Although both had similar soil protection qualities, runoff was very different. The runoff from the jute net was 35% and the jute mat 247% of the control. Results demonstrate the effectiveness of jute net for erosion and runoff control, while the jute mat may both conserve soil and 'harvest' rain or redirect runoff.
    • Green business models in the construction sector: An analysis of outcomes and benefits

      Abuzainab, A; Qadri, A; Arif, Mohammed; Kulonda, D (Emerald, 2017-10-01)
      Purpose –Green business models (GBMs) in the construction sector represent the logic of green value creation and capture. Hence, the call to examine GBMs is growing ever louder. The aim is to identify benefits of GBMs by adopting five essential elements of the GBM from the literature: green value proposition (GVP); target group (TG); key activities (KA); key resources (KR); and financial logic (FL). Design/methodology/approach Nineteen semi-structured interviews are conducted with construction sector practitioners and academics in the UK. Thematic analysis is used to obtain benefits of GBMs. Further, the Interpretive Ranking Process (IRP) is used to examine which elements of the GBM have a dominant role in providing benefits to construction businesses. Findings – The benefits are grouped into three themes: credibility/reputation benefits; financial benefits; and long-term viability benefits. The IRP model shows that the element of KR is the most important when evaluated against these three benefit themes. Implications – Linking GBM elements and benefits will help companies in the construction sector to analyse the business case of embracing environmental sustainability. Originality/value - This research is one of the few empirical academic works investigating the benefits of GBMs in the construction sector. The IRP method is a novel contribution to GBMs and construction research.
    • Green business models transformation: evidence from the UK construction sector

      Abuzeinab, Amal; Arif, Mohammed; Kulonda, Dennis J.; Awuzie, Bankole Osita (Emerald, 2016-11-07)
      Purpose – Sustainability has the potential to bring enormous benefits to our built environment. To release this potential, a change in business models is required. Green business models (GBMs) transformation is investigated by adopting five essential elements of green value creation and capture: Green Value proposition (GVP), Target Group (TG) Key Activities (KA), Key Resources (KR), and Financial Logic (FL). Design/methodology/approach – In this qualitative study, 19 semi-structured interviews are conducted. Interviewees were selected purposively. The emergent data is analysed with the aid of themes. Findings – It is observed that significant effort is being made towards enabling the transformation of certain elements pertinent to green value creation: KA and KR. This is particularly so when compared to other elements like GVP, TG, and FL. Implications –Findings from this study should encourage construction managers to align their extant BMs to green activities hence enabling new approaches to green value creation and capture. Furthermore, the study will aid in improving the environmental and economic positions of the value chain within the construction sector. Originality/value - This research is one of the few empirical academic works investigating GBMs in the construction sector.
    • Influence of vehicular traffic on a major trunk road on rural air quality in UK

      Obara, Paul G.; Obara, Chizi E.; Roberts, Clive L.; Young, Christopher; Williams, Craig D. (Elsevier, 2011)
      Although poor air quality has long been linked to urban areas, it is seemingly apparent that many rural areas have locations where air quality strategy objectives may be threatened in the wake of increasing vehicular traffic. This study examined the contributions of traffic towards air quality status by conducting monthly assessment of rural air quality along the A49 trunk road. The aim is to observe differences in main pollutant concentrations depending on the distance from the road. Monthly data of particulate deposits were monitored at roadsides, 50 m and 100 m distance in proximity to the A49 trunk road over a 22-month period (June 2008–Apr 2010). Direct analysis by SEM-EDS, ICP-MS, PTrak and XRF revealed a seasonal, intra-and inter-site variations and a distance–decay relationship. However, at some locations with increased vehicular activities, this relationship was altered.
    • Insolvency and resolution of construction contract disputes by adjudication in the UK construction industry

      Ndekugri, Issaka E.; Russell, Victoria (Taylor & Francis, 2005)
      The Housing Grants, Construction and Regeneration Act 1996 provides that a party to a construction contract has a right, at any time, to refer any dispute under the contract for adjudication. This resolution method requires a neutral third party, the adjudicator, to determine the dispute within 28 days after receipt of the referral regardless of the complexity of the issues in dispute. The decision is to be implemented even if it is palpably wrong in fact or law. A key assumption of this legislation is that any mistakes made by an adjudicator can be corrected by reference of the same to litigation or arbitration. It is a major concern that restoration of the parties to their correct positions may become impossible where, after implementation of an adjudicator's mistaken decision, the beneficiary of the decision becomes insolvent. This article is a critical review of all the cases in which the courts have dealt with the effect of insolvency on the right to adjudicate and the enforceability of adjudicators' decisions. Two main conclusions are derived from the review. First, the court may decline to enforce an adjudicator's payment decision where there is strong evidence that, on account of formal insolvency, the payee would be unable to make repayment if final resolution of the dispute necessitates it. Second, the only exception so far to the general right to refer to adjudication arises where the other party is in administration. (Taylor & Francis)
    • Outsourcing the Risk Analysis Function in 'Private Finance Initiative' Projects

      Akintoye, Akintola; Beck, Matthias; Hardcastle, Cliff; Chinyio, Ezekiel A.; Asenova, Darinka (University of Salford, 2003)
      The optimisation of risk transfer and risk management in ‘Private Finance Initiative’ (PFI) projects involves the accurate assessment of these risks. The manner in which risks are analysed and the extent, to which this function is outsourced in PFI projects, is examined in this article. The discussions are informed by an investigation conducted at Glasgow Caledonian University. Literature was reviewed, upon which a survey instrument was developed. A qualitative methodology was adopted, and involved a total of 90 interviews with diverse PFI participants in the UK. The ‘AtlasTi’ software was utilised in the analysis of data. The interviews revealed that the bulk of the risk analysis function in PFI is usually done in-house, while a minor part is often outsourced to technical, legal and financial cum insurance experts. Other disciplines consulted, albeit occasionally, include traffic engineering, environmental science, planning and surveying. The objective is to outsource those aspects where in-house expertise is deficient. When tasked with risk analysis, consultants were adjudged to usually render a good job.
    • Private Finance Initiative in the Healthcare Sector: Trends and Risk Assessment

      Akintoye, Akintola; Chinyio, Ezekiel A. (Emerald Group Publishing Ltd., 2005)
      Abstract: Purpose – The UK Government has now adopted Private Finance Initiative (PFI) as a major vehicle for the delivery of additional resources to the health sector in order to achieve a greater investment in healthcare facilities. The purpose of this paper is to examine the trends and risk assessment of the PFI in the healthcare sector. Design/methodology/approach – The paper employed secondary data and interviews of key participants in two hospital PFI projects to highlight developments in healthcare PFI and the risk management of hospital projects. Findings – The results show that the use of PFI in the provision of healthcare is increasing in terms of number, capital value and size of projects. What emerged in the healthcare PFI project was a usage of a plethora of risk management techniques, albeit to varying degrees. Experience appeared to be the prime risk assessment technique employed, while risk avoidance was first explored before pricing and allocating any residual risks. “Risk prompts”, such as using checklists and risk registers were also useful in the identification of risks. Among all participants, insurance cover and sub-contracting appear to be the most prominent strategies employed for managing out the risks. Originality/value – The negotiations that precede the signing of a healthcare PFI project contract had an impact on the final choice of facilities or their specifications. The two contracting parties sought a balance between an optimal allocation of risks, choice of facilities and project price. Although the risk management techniques being used are generic in nature, there is still no evidence at the moment to show that these are appropriate for PFI projects. It is important that further investigation is undertaken to assess the level of current skills in risk management techniques to deal with PFI projects and the extent to which these techniques are appropriate to tackle complex healthcare PFI projects.

    • The relationship between the last planner® system and collaborative planning practice in UK construction

      Daniel, EI; Pasquire, C; Dickens, G; Ballard, HG (Emerald, 2017-05-15)
      © 2017 Emerald Publishing Limited. Purpose: The purpose of this paper is to identify how the newly emerging UK practice of "collaborative planning" (CP) for construction project delivery aligns with the advocated principles of the global last planner system (LPS) of production planning and control. Design/methodology/approach: A mixed, qualitative, exploratory approach was adopted for the study. This entailed qualitative data through three techniques, namely: semi-structured interviews, documents analysis, and structured observation. In total, 30 in-depth interviews were conducted over a 12 month period with lean construction consultants, clients, main contractors, and subcontractors drawn from the building, highways and infrastructure and rail sector. In all, 15 projects were visited where practices were observed. Findings: The study reveals that the current practice of CP in the UK partially aligns with the LPS principles. Where practitioners have heard of the LPS they believe it to be the same practice as CP. Research limitations/implications: This study is limited to 30 interviews, observation of 15 projects and document analysis. The aim of the study is not to generalise the findings, however, since the study examined top construction companies and practitioners in the UK and the findings were consistent across the sample, some conclusions could be made. The study is also limited to examining the construction phase only, future studies should incorporate the design phase. Practical implications: A clear identification of the elements of current practice compared to the components of the LPS provides a contribution to the future practice of project production planning and management in the construction industry. Social implications: The study highlights a continuing resistance to collaboration within the industry. This resistance is subtly embedded within implemented practices even though they are based on collaborative working for their success. Originality/value: This is among the first studies in the UK that comprehensively examines and reports the application of LPS/CP practice in construction across the major construction sectors. Future studies could build on the findings from this work to develop an approach/methodology to improve the current practice.

    • The Effect of Coal and Diesel Particulates on the Weathering Loss of Portland Limestone in an Urban Environment

      Searle, David E.; Mitchell, David J. (Amsterdam: Elsevier, 2006)
      Due to reductions in domestic usage, legislation and changes in fuel use, coal derived particulates in the UK urban atmosphere have been significantly reduced. However, a large increase in road usage and an expansion in the use of diesel engines, has meant that the majority of particulates, now present in the urban atmosphere, originate from vehicle exhausts. Particulate matter, resulting from coal combustion, has been recorded as being present in black patinas observed on some historic stone buildings and monuments and has been associated with accelerated weathering of stone surfaces as a result of enhanced gypsum formation. In contrast, the effects of particulates resulting from vehicle exhaust on stone are much less understood. To investigate this, a comparative study was undertaken using the technique of microcatchments under ambient atmospheric conditions. This compared the elemental composition and volume of precipitation runoff from Portland Limestone coated with three different particulate treatments. Treatments consisted of coal and diesel particulates, both separately and in combination. Combining these treatments attempts to investigate any synergistic effects that may occur when coal derived particulates are overlain by layers formed by particulates from more contemporary sources. It was found that diesel-coated samples were much darker in appearance and showed a significant reduction (P < 0.05) in the overall rate of weathering loss when compared to untreated samples. Microcatchment runoff volume was reduced from diesel-coated Portland Limestone compared to untreated stone. Enhanced surface temperatures may be increasing the rate of moisture loss from the pore network between rainfall events. Since, generally, the pores must be full before runoff can occur, the reduction may be due to the differential volume of empty pore space between diesel-coated and untreated Portland Limestone.
    • The Performance of Contractors in Japan, the UK and the US: A Comparative Evaluation of Construction Cost

      Xiao, Hong; Proverbs, David G. (Routledge (Taylor & Francis), 2002)
      Globalization of the world economy demands that performance comparisons are undertaken at an international level. A new research protocol has been developed for comparing contractor performance internationally by combining the appropriate characteristics of two established approaches in order to balance the requirements of comparability and representativeness. This new approach is used to reveal some important international performance characteristics among Japanese, UK and US contractors. Building costs in the UK, when adjusted for exchange rate fluctuations, are significantly higher than those in Japan and the USA. Furthermore, cost certainty and client satisfaction are higher in Japan than in the UK, but there is no significant difference between Japan and the USA. Disparities in cost performance between the three countries are believed to originate from differences in the relationships between contractors and clients and also in the construction process.

    • Understanding the Construction Client

      Boyd, David; Chinyio, Ezekiel A. (John Wiley, 2006)
      This book breaks new ground by creating a framework to understand clients' actions and needs. Most construction management books focus on improving the construction process; this one focuses on a better engagement with the client. It challenges conceptions of both the construction industry and clients' businesses so that a more effective process and greater client satisfaction can be achieved. The book suggests that 'buildings are not about building but about changing and developing the client'. The technical, organisational and psychological aspects of this are described and analysed in detail so that current experience can be explained and better practice determined. The book offers well-researched information about clients in a number of sectors - developers, supermarkets, NHS, government, airports and housing associations - which will help you understand what these client's business or service needs are and how construction fits into this. It demonstrates how to develop an appreciation of the client's perspective with a toolkit for ensuring successful client engagement. This makes Understanding the Construction Client a user-friendly and practical guide, as well as significant text for academia. (Blackwell Publishing)

    • Use of palm-mat geotextiles for rainsplash erosion control

      Bhattacharyya, Ranjan; Fullen, Michael A.; Davies, Kathleen; Booth, Colin A. (Elsevier, 2010)
      Soil detachment by raindrop action (rainsplash erosion) is a very important subprocess of erosion by water. It is a particular problem in the UK as most soils are sandy or loamy sand in texture and lands have gentle to medium slope. However, few studies report potential rainsplash erosion control options under field conditions. Hence, the utilization of palm-mat geotextiles as a rainsplash erosion control technique was investigated at Hilton, east Shropshire, U.K. (52°33′5.7″ N, 2°19′18.3″ W). Geotextile-mats constructed from Borassus aethiopum (Borassus palm of West Africa) and Mauritia flexuosa (Buriti palm of South America) leaves are termed Borassus mats and Buriti mats, respectively. Two-year field experiments were conducted at Hilton to study the effects of emplacing Borassus and Buriti mats on rainsplash erosion of a loamy sand soil. Two sets (12 plots each) of experiments were established to study the effects of these mats on splash height and splash erosion. Splash height needs to be known to assess the transport mechanism of major soil fraction and its constituents on sloping land by rainsplash. In both sets, six randomly-selected plots were covered with mats, and the rest were bare. Results (during 22/01/2007 23/01/2009; total precipitation= 1731.5 mm) show that Borassus mat-covered plots had ∼89% (Pb0.001) less total splash erosion (2.97 kg m−2) than bare plots (27.02 kg m−2). Comparatively, mean splash height from Borassus matcovered plots (0.12 m) was significantly (Pb0.001) less than the bare plots, by ∼54%. However, Buriti matcover on bare plots had no significant (PN0.05) effect in rainsplash erosion control during that period, although plots with Buriti mats significantly (Pb0.05) decreased splash height (by ∼18%) compared with bare plots (0.26 m). Buriti mats, probably due to their ∼43, 62 and 50% lower cover percentage (44%), mass per unit area (413 g−2) and thickness (10 mm), respectively, compared with Borassus mats, were not effective in rainsplash erosion control. Both mats did not significantly (PN0.05) improve selected soil properties (i.e., soil organic matter, particle size distribution, aggregate stability and total soil carbon) as soil organic matter (SOM) input from mat-decomposition was much less than total SOM content. However, the changes in fine and medium sand contents (after 2 years) in the Borassus covered plots were significantly (Pb0.05; n=6) related to the total rainsplash erosion during 2007 2009. Emplacement of Borassus and Buriti mats on bare soils did not decrease SOM contents after 2 years, indicating that improvements in some soil properties might occur over longer durations. After ∼10 months, Buriti mats lost ∼70% of their initial weight (Pb0.001) and their initial cover percentage (C, %) decreased drastically (Pb0.05); whereas, Borassus mats maintained similar C to the initial condition, although mass per unit area decreased by ∼20% (Pb0.05). Moreover, the functional longevity of Borassus mats was ∼2 years against only 1 year for Buriti mats. Hence, use of Borassus mats is highly effective for rainsplash erosion control in the UK.
