Full textAbstract:
The past year has seen a downturn in the number of new mining and infrastructure projects in Australia. Despite that, the authors are noticing a continuation of the trend towards a greater use of engineering, procurement and construction management (EPCM) style contracting. The increased use of EPCM contracts is in part due to projects becoming larger and more complex. As these projects can only be delivered by multiple contractors who all seek to limit their liability, the EPCM contract offers a useful framework for coordinating and managing those contractors, and maximising the owner’s recourse to them. This is particularly so in the oil and gas industry, with many projects using this form of project delivery. As there is no standard-form EPCM contract, however, and given the complex technical nature of these types of projects, negotiating an EPCM contract can be fraught with danger, especially for owners who may not have used this style of contract before. This paper discusses the unique characteristics of the EPCM contract (particularly in contrast to the engineering, procurement and construction style contract), the typical risk allocation, and the creative use of compensation and incentive regimes to drive optimum performance. The EPCM model is not suited to all projects, but if it is appropriately negotiated and drafted, and is well managed by an appropriately skilled and resourced owner’s team, it can provide a platform for excellence in project delivery.

Full textAbstract:
Purpose – The purpose of this paper is to evaluate the effectiveness of the statutory adjudication legislation in Western Australia against its stated aims. Design/methodology/approach – The four objectives of the Western Australia Construction Contracts Act 2004 were identified. For each objective a number of criteria has been devised. In total, 22 registered adjudicators were interviewed, representing 28 per cent of all adjudicators in Western Australia. The interviewees were divided into two groups, one with legal background (being both lawyer and adjudicator), the other without (construction professionals). They were asked to evaluate the criteria against a five-point Likert scale in addition to open ended comments. Mann-Whitney U tests were used to examine whether there were significant differences between the two groups. Annual reports of Building Commissioner, database of the WA State Administrative Tribunal and some law cases were also referred to. Findings – It is found that the West Coast Model is fair to both parties, the adjudications are generally completed speedily according to the prescribed timeframe, and they have been conducted in various levels of formalities. Adjudications are very cost effective for larger claims. However, they are not so for smaller claims. The increasing uptake rate shows that adjudication is getting more popular, while the low appeal rate shows that decisions on dismissal are fair. Research limitations/implications – The adjudicators’ opinions are only part of the overall picture and that more research on this topic needs to be done. Originality/value – There have been two distinct legislative models in Australia, commonly known as East Coast Model and West Coast Model. A number of authors have called for a national dual model incorporating both current models. However, it might be too early to discuss the national dual model when there have been very few evaluations on the West Coast Model and among the few there have been problems in the research design. This paper seeks to bridge the gap by evaluating the West Coast Model against its stated aims.

Purpose In Australia, national harmonisation of occupational health and safety (OHS) regulation was pursued through the development of model Work Health and Safety legislation. The model Work Health and Safety Regulations specify that construction works above a threshold cost of AU$250,000 are deemed to be construction projects requiring the appointment of a principal contractor with duties relating to OHS planning and coordination. The purpose of this paper is to explore the effectiveness of the monetary threshold as a suitable trigger for specific OHS planning and coordination duties. Design/methodology/approach Interviews were conducted with 46 Australian construction industry stakeholders, including union representatives, employer groups, construction firm representatives and regulators, as well as four international construction OHS experts, to explore perceptions about the effectiveness of the monetary threshold. Two construction scenarios were also modelled to test for variability in operation of the threshold by geographical location of works and design conditions. Findings The monetary threshold was perceived to be subject to two forms of capture problem, reflecting inadvertent capture of low risk works or failure to capture high risk works. Organisations were also reported to deliberately split contracts to avoid capture by the threshold. The cost-estimate modelling revealed inequalities and variation in the operation of the monetary threshold by geographic location and design specification. Practical implications The analysis suggests that limitations inherent in the use of a monetary threshold to trigger duties relating to OHS planning and coordination in construction works. Opportunities to use more sophisticated risk-based mechanisms are considered. Originality/value The study explores a fundamental challenge of risk-based OHS regulation, i.e., how to ensure that workers’ health and safety are adequately protected without creating an unnecessarily high regulatory burden. The research provides evidence that using a monetary value as a proxy measure for OHS risk in construction projects may be problematic.

Full textAbstract:
Public–Private Partnership (P3) handback experience is very limited in the U.S. and internationally. This paper analyzes the handback experience in three highway P3 projects: East-Link Bridge in Dublin, Ireland, Highway 4 (VT4 Järvenpää-Lahti) in Finland, and M4 Tollway in New South Wales, Australia. Two of the projects did not have any material handback clauses in their P3 contracts. Still, the handback processes and outcomes of all three projects are considered successful. The projects experienced a relatively smooth handback process, mainly because of very good working relationships between the contracting authority and the P3 concessionaire. There have not been significant technical quality concerns or problems in the years immediately following the handback. Other drivers for successful P3 handback include clear definition of handback requirements, sufficient incentives and protections, clear procedures and joint inspection processes, a collaborative approach, and workforce sustainment. These contractual requirements and financial incentives and protections are very beneficial as working relationships between P3 agencies and concessionaires will not always be excellent, which could lead to less smooth handback processes.

Building Information Modelling (BIM) is seen as a panacea to many of the ills confronting the Architectural, Engineering and Construction (AEC) sector. In spite of its well documented benefits the widespread integration of BIM into the project lifecycle is yet to occur. One commonly identified barrier to BIM adoption is the perceived legal risks associated with its integration, coupled with the need for implementation in a collaborative environment. Many existing standardised contracts used in the Australian AEC industry were drafted before the emergence of BIM. As BIM continues to become ingrained in the delivery process the shortcomings of these existing contracts have become apparent. This paper reports on a study that reviewed and consolidated the contractual and legal concerns associated with BIM implementation. The findings of the review were used to conduct a qualitative content analysis of the GC21 2nd edition, an Australian standardised construction contract, to identify possible changes to facilitate the implementation of BIM in a collaborative environment. The findings identified a number of changes including the need to adopt a collaborative contract structure with equitable risk and reward mechanisms, recognition of the model as a contract document and the need for standardisation of communication/information exchange.

Full textAbstract:
ANZAC, the acronym of the Australian and New Zealand Army Corps, is the name given to a new class often frigates under construction for the Royal Australian and Royal New Zealand Navies. The prime contract was awarded in November 1989, and a separate design sub-contract was awarded concurrently. HMAS ANZAC, the first of eight ships for the Royal Australian Navy (RAN), was delivered in March 1996. HMNZS Te Kaha, the first of two ships for the Royal New Zealand Navy (RNZN), was delivered in May 1997. The paper describes the collaborative process, involving the Australian Department of Defence, the New Zealand Ministry of Defence, and Defence Industry in Australia, New Zealand and overseas, for the design and production of the ships. The need to maximise the level of Australian and New Zealand industrial involvement, led to a process of international competition between prospective suppliers, and significant configuration changes from the contract design baseline. Delivery of the first ship was extended to accommodate the revised approach, and in the event only five months additional time proved necessary. Although formal acceptance of HMAS ANZAC is not due until the completion of operational test and evaluation, the contractor's sea trials have successfully demonstrated the performance exceeding the requirements and the expectations of the RAN. The paper also describes the growing maturity of Australia's naval shipbuilding industry. It suggests some lessons learned from the project, and identifies issues important for the further development and sustainability of the industry. It advocates the need for agreed methodologies to evaluate the productivity of the various elements of the shipbuilding process, and to help ensure the establishment and maintenance of world competitive costs and quality.

Full textAbstract:
Very little research has examined the emergence of Western Muslims into the elite professions that are central to the operation of the capitalist free market and that serve as a central location of economic and political power. Less research still has examined how this is shaping citizenship among Muslims and the future of Islam in the West. These professions include finance, trade and auditing and supporting free market infrastructure including commercial law, consulting and the entrepreneurial arms of government public service. Many Muslim men and women in these professions maintain a commitment to their faith and are often at the forefront of identifying opportunities for the application of Islamic principles to the free market through the development of social engineering mechanisms such as Islamic finance and home loans, Islamic wills, marriage contracts, businesses and context-specific solutions for Muslim clients. These may have a potentially profound impact on belonging and practice for current and future generations of Western Muslims. The political and economic clout (and broader potential public appeal) of these new Muslim elites often significantly outweighs that of Imams and Sheikhs and thus challenges traditional textually based Islam. This article, grounded in empirical research, seeks to build upon very limited research looking at Muslim elites, exploring these developments with specific reference to professionals working in Islamic finance and law across the Western contexts of Australia and the United States, two countries with capitalist free markets and significant Muslim minorities.

AbstractThe late 1950s were chiefly characterised by immense frustration and very difficult relations with the British designers Freeman, Fox and Partners (FFP). A crucial change forced by Bowen and initially resisted by FFP, was to call for competitive bids. Despite the pressure to select a British firm for the construction contract it was awarded to a German firm, Maschinenfabrik Augsburg-Nürnberg (MAN). This dramatically illustrates the extent to which an ex-British colony was now truly independent and capable of making what certainly transpired to be an excellent solution. The combination of the innovative UK FFP mechanical design, the efficient MAN German construction and the Australian radio systems engineering was a great success.

Automated decision support systems with high stake decision processes are frequently controversial. The Online Compliance Intervention (herewith “OCI” or “RoboDebt”) is a system of compliance implemented with the intention to facilitate automatic issuance of statutory debt notices to individuals, taking a receipt of welfare payments and exceeding their entitlement. The system appears to employ rudimentary data scraping and expert systems to determine whether notices should be validly issued. However, many individuals that take receipt of debt notices assert that they were issued in error. The commentary on the system has resulted in a lot of conflation of the system with other system types and caused many to question the role of decision of support systems in public administration given the potentially deleterious impacts of such systems for the most vulnerable. The authors employ a taxonomy of Robotic Process Automation (RPA) issues, to review the OCI and RPA more generally. This paper identifies potential problems of bias, inconsistency, procedural fairness, and overall systematic error. This research also considers a series of RoboDebt specific issues regarding contractor arrangements and the potential impact of the system for Australia's Indigenous population. The authors offer a set of recommendations based on the observed challenges, emphasizing the importance of moderation, independent algorithmic audits, and ongoing reviews. Most notably, this paper emphasizes the need for greater transparency and a broadening of criteria to determine vulnerability that encompasses, temporal, geographic, and technological considerations.

Full textAbstract:
Experience has shown that regional factors can contribute to significant variability in decommissioning costs for offshore platforms. Nevertheless, previous studies aimed at estimating decommissioning costs have been valuable inputs for operators, regulators and decommissioning contractors as they develop abandonment and decommissioning strategies and public policy. Estimated costs associated with decommissioning offshore oil and gas platforms in Australia have not been reported widely in the open literature. This paper summarises the physical and regulatory environment in Australia, and develops a cost model which reflects the decommissioning challenges for fixed platforms in this remote region. This cost model could be readily applied to other remote petroleum provinces provided that mobilization times and the nature of the local ocean environment are known. The total cost of decommissioning all 39 current fixed platforms in Australian waters is estimated to be between US$845 and US$1044 million.

Full textAbstract:
In a sector that is seeing unprecedented levels of activity, the opportunity to assess skill sets to take an integrated approach to subsea system design can be challenging. Contracting strategies that compartmentalise engineering scopes at any stage of the project lifecycle also require a high level of interface and project management. An informed methodology ensures a holistic approach to subsea design and interfaces is undertaken. Many challenges to subsea design are influenced by other disciplines such as reservoir, production technology, process, flow assurance and facilities engineering. Traditionally these considerations are outside of subsea engineering scopes and are controlled at the next level in the supply chain, or within other designers or contractors. This paper considers not only the regional challenges to pipeline and riser design in the Australian region, but also how the inclusion of an integrated approach encompassing multi-disciplined teams allows a more informed outcome. Using these highly skilled teams, this approach can: • Reduce interface management requirements; • Reduce design cycles; • Create optimised solutions within a shorter timescale. This has the potential to reduce overall CAPEX and OPEX costs by identifying value and reducing uncertainties in key areas. This adds significant value in the current climate of extended procurement lead times and resource constraints. Examples of current projects demonstrating how this approach can be applied in concept selection through to detailed design are described. Practical examples of how the possible design outcomes have been assessed using this approach are detailed. Considerations of how key factors such as subsurface, field layout, architecture, materials selection, operability, construction and HSE influence pipeline and riser design are also discussed.

Full textAbstract:
This paper describes temporal variations in embedment of several existing pipelines on the North-West Shelf (NWS) of Australia, and the sediment mobility processes that cause them. Distinct and explainable patterns in the extent, distribution and rate of the development of pipeline embedment have been revealed through systematic detailed examination of repeated annual integrity surveys by ROV. This represents a unique data-set that has been used to optimize the reliability of a newly designed pipeline. This paper explains why these clear findings should not be overlooked in both the buckling and stability design of initially unburied pipelines, which is in contrast to currently established industry practice. This new information supports the presumption that conventional approaches for calculating the hydrodynamic stability of unburied pipelines may be more conservative than necessary. Conversely, and arguably more importantly, it is shown that conventionally accepted methods for calculating pipe-seabed resistance forces when planning buckling schemes should be considered unsafe if embedment due to sediment mobility is possible. Consequently, this paper proposes an innovative calculation methodology that statistically captures these sediment mobility effects, and which facilitates a more justifiable geotechnical input to pipeline engineering than what is conventionally adopted. This methodology is currently being used by the authors as a state-of-the-art design practice for unburied offshore pipelines in regions of sediment mobility.

Full textAbstract:
The behavior of pipelines, cables and umbilicals on rocky seabeds has to date received little research attention. This is despite the marine renewable energy and oil and gas industries relying on these ‘pipes’ to cross a variety of rocky seabed types in the presence of extreme metocean conditions. Present design solutions are challenging and costly, yet there remains a track record of in-service failures. This paper forms part of a wider research effort being undertaken by the University of Western Australia (UWA) into pipe behavior on rocky seabeds. This work includes the effects intermittent gaps have on hydrodynamic forces, the effect of seabed roughness on enhanced boundary layer thickness and the validity of existing hydrodynamic force models for small diameter cables. In this paper, the lateral resistance of pipes on rocky seabeds is investigated using both physical and numerical testing of model pipes over artificially-created rocky seabeds. Four model pipes of varying diameter have been displaced laterally over 1 m square model rocky seabeds, with a range of pipe to rock diameters. The lateral resistance of the physical pipe tests were recorded using load cells and a digital data-logger. Analysis of the physical test results has enabled comparison to (and refinement of) numerical models as well as improved understanding of the importance of different parameters. Our results show peak frictions above 6 arising under conditions where interface friction is only about 0.3, which contrasts dramatically with the friction value of 0.6 nominated in F109. This work contributes towards generation of new design methods suitable for application to field conditions.

Full textAbstract:
In April 2012 Heerema Marine Contractors (HMC) successfully performed the float-over of the North Rankin B topsides. With a weight of 24,250mT it is the heaviest deck installed in a single piece in the harsh offshore environment of Australia’s North West Shelf to date. During years of preparations extensive hydrodynamic analyses have been undertaken to achieve design loads, optimize the float-over equipment and ultimately determine operability limits for the installation. As the float-over analysis contains various components with non-linear characteristics (e.g. fenders, leg mating units, mooring lines), a non-linear problem solving approach was used. The selected analysis tools use an efficient time step integration enabling a large number of simulations to be run. The strong non-linearity of the system requires a Monte Carlo simulation to obtain statistically reliable results. The numerical model included purpose built modules for the float-over equipment (such as LMUs) taking into account relevant details and project specific geometries. Available data from model tests was used in calibration and validation of the model. Towards the offshore execution phase, the limiting combinations of wind sea and swell waves were identified. Forthese combinations the system response remained (just) within its ‘Not To Exceed’ values. During the offshore operation, prior to the actual float-over, the spectral wave conditions, wind and current were constantly monitored to validate the forecasts. Also the barge motions were measured and compared against results from the numerical models. This was used in support of the final decision to proceed with the float-over operation.

Full textAbstract:
Steel catenary risers (SCRs) are economical to assemble and install compared to conventional vertical risers. However, accurate evaluation of the fatigue life of an SCR remains a major challenge due to uncertainty surrounding the interaction forces at the seabed within the touchdown zone (TDZ). Fatigue life predictions are heavily dependant on the assumed stiffness between the riser and the seabed and therefore an accurate assessment of seabed stiffness — or more specifically the nonlinear pipe-soil resistance — is required. During the lifespan of an SCR, vessel motions due to environmental loading cause repeated penetration of the riser into the seabed within the TDZ. This behaviour makes assessment of seabed stiffness difficult due to the gross deformations of the seabed and the resulting soil remoulding and water entrainment. This paper describes a model test in which the movement of a length of riser pipe was simulated within the geotechnical beam centrifuge at the University of Western Australia. The model soil was soft, lightly over-consolidated kaolin clay with a linearly increasing shear strength profile with depth, typical of deepwater conditions. The pipe was cycled over a fixed vertical distance from an invert embedment of 0.5 diameters to above the soil surface. This range represents a typical vertical oscillation range of a section of riser within the TDZ during storm loading. The results indicate a significant degradation in the vertical pipe-soil resistance during cyclic vertical movements. Due to the cyclic degradation in soil strength, the component of the vertical resistance created by buoyancy was significant, particularly due to the influence of heave. A new approach to the interpretation of heave-enhanced buoyancy was used to extract the separate influences of soil strength and buoyancy, allowing the cyclic degradation in strength to be quantified. During cycling, the soil strength reduced by a factor of 7.5 relative to the initial penetration stage. This degradation was more significant than the reduction in soil strength during a cyclic T-bar penetration test. This contrast can be attributed to the breakaway of the pipe from the soil surface which allowed water entrainment. This dramatic loss of strength and therefore secant stiffness, and the significance of the buoyancy term in the total vertical pipe-soil resistance, has implications for the fatigue assessment of SCRs.
