Impact of contractor internal tendering procedure governance on tender win-rates: How procedures can be improved

Construction contractors normally, though not always, pursue tenders with the expectation of winning and subsequently making a project profit. Corporate governance (CG) constraints, risk appetite, and selected tender strategy impact contractors' tendered prices and any associated qualifications. Therefore, failure to win may not constitute 'failure' in senior executive's eyes. Increasing CG within some jurisdictions has led to more complicated contractor internal tendering procedures (ITP) with layers of management reviews and risk committee sign-offs. The question arises as to whether these changes make any difference to tender win rates and subsequent project outcomes. A series of qualitative semi-structured interviews were undertaken with 25 high-profile Australasian based construction contractors (11, either directly or via parent companies, operate internationally-Europe, Africa, Asia and North America), providing a mix of publicly listed and privately owned companies, as part of a wider research program investigating the efficiency and effectiveness of contractors' ITP. Moving beyond previous research limitations of smaller contractors (often sub-AU$100m turnover) this qualitative research looks at much larger contractors. Content analyses of the interview transcripts found that, while contractors talked equally about 'win' and 'lose', most did not see losing a tender as 'failure'. Only a quarter felt their changed ITP made a difference to their tender win-rate. Somewhat unexpectedly interview findings suggest that approximately three-quarters of contractors have ITP that do not formally require lessons learned (LL) from previous tenders nor projects to be inputs in subsequent tender pursuits. Larger contractors (over AU$500m turnover) were twice as likely to discuss LL, indicating different governance approaches to tender outcome expectations. Informal LL approaches were applied to clients' reputations (particularly payment) in bid/no-bid decisions. Interviewee suggestions of processes by which contractors can improve resultantly their LL procedures, as part of their CG, are also presented

Rethinking the tendering frameworks of construction contractors in the context of a soft systems methodology approach

Limited research has been conducted on the internal tendering procedures (ITP) of construction contractors because of the commercially sensitive and confidential nature of the subject matter. This limitation explains the reluctance of contractors to undergo interviews. Existing research (outside bid/no-bid and margin decision factor identification and subsequent decision modeling development) only begins to provide insights into key tendering stages, particularly around risk assessments and corporate review processes. Early research suggested one to three review stages. However, when considering the whole work procurement process from prospect identification to contract execution, five to seven series of reviews can be arguably applied by some contractors, wherein some reviews stepped through several layers of internal senior management. Tendering processes were presented as flowchart models that traditionally follow “hard” system (rectangular shapes and straight line arrows) steps, which suggest that a precise process also leads to precise results. However, given that contractors do not win every tender they submit, the process is less precise than that suggested in rigidly structured flowcharts. Twenty-five detailed semi-structured interviews were held with purposely selected high-profile publicly and privately owned construction companies in Australia with significantly varied turnovers. Analyses show that contractors are concerned about the negative effects of increasing corporate governance demands, with many stating that people involved are the most critical element to tendering success. A new way of presenting the ITP of contractors is assessed using a soft systems methodology (SSM) approach. SSM offers an alternative way of considering human interaction challenges within the ITP of contractors, which needs to be tested with the industry. The format graphics of SSM guidelines are presented as a way of offering contractors a different approach, which may assist individuals who are looking to re-structure their tendering activities in a more humanistic and less rigid procedural approach

Affirmative action and effort choice: An experimental investigation (WIDER Working Paper 2016/54)

We study the effect of affirmative action on effort in an experiment conducted in high schools in socioeconomically disadvantaged areas in Queensland, Australia. All participating schools have a large representation of indigenous Australians, a population group that is frequently targeted by affirmative action. Our participants perform a simple real-effort task in a competitive setting. Those ranked in the top third receive a high piece-rate payment and all the others receive a low payment. We introduce affirmative action by providing the lowest (bottom third) performers with a positive handicap increasing their chances to achieve the high payment target. Our findings show that the policy increases effort of those that it aims to favour, without discouraging effort of those who are indirectly penalized by affirmative action

Meeting Curation Challenges in a Neuroimaging Group

The SCARP project is a series of short studies with two aims; firstly to discover more about disciplinary approaches and attitudes to digital curation through ‘immersion’ in selected cases; secondly to apply known good practice, and where possible, identify new lessons from practice in the selected discipline areas. The study summarised here is of the Neuroimaging Group in the University of Edinburgh’s Division of Psychiatry, which plays a leading role in eScience collaborations to improve the infrastructure for neuroimaging data integration and reuse. The Group also aims to address growing data storage and curation needs, given the capabilities afforded by new infrastructure. The study briefly reviews the policy context and current challenges to data integration and sharing in the neuroimaging field. It then describes how curation and preservation risks and opportunities for change were identified throughout the curation lifecycle; and their context appreciated through field study in the research site. The results are consistent with studies of neuroimaging eInfrastructure that emphasise the role of local data sharing and reuse practices. These sustain mutual awareness of datasets and experimental protocols through sharing peer to peer, and among senior researchers and students, enabling continuity in research and flexibility in project work. This “human infrastructure” is taken into account in considering next steps for curation and preservation of the Group’s datasets and a phased approach to supporting data documentation

The identification of Staphylococcus aureus factors required for pathogenicity and growth in human blood

Staphylococcus aureus is a human commensal but also has devastating potential as an opportunist pathogen. S. aureus bacteraemia is often associated with an adverse outcome. To identify potential targets for novel control approaches we have identified S. aureus components that are required for growth on human blood. An ordered transposon mutant library was screened, identifying 9 genes involved specifically in haemolysis or growth on human blood agar compared to the parental strain. Three genes (purA, purB and pabA) were subsequently found to be required for pathogenesis in the zebrafish embryo infection model. The pabA growth defect was specific to the red blood cell component of human blood, showing no growth difference compared to the parental strain on human serum, human plasma, sheep or horse blood. PabA is required in the tetrahydrofolate (THF) biosynthesis pathway. The pabA growth defect was found to be due to a combination of loss of THF-dependent dTMP production by the enzyme ThyA and an increased demand for pyrimidines in human blood. Our work highlights pabA and the pyrimidine salvage pathway as potential targets for novel therapeutics and suggests a previously undefined role for a human blood factor in the activity of sulphonamide antibiotics
