To what extent is the use of a project neutral prevalent in construction projects? What are the benefits?
Today the use of a project neutral internationally is increasing markedly, albeit not under that name.
My first experience of the process was when I assisted a mentor of mine, Peter MacGillivray, in that role, pre-statutory adjudication. Both parties to a dispute sought an independent opinion on several related issues on a project. Unbeknown to us at the time the parties had agreed to be bound by Peter’s opinion; that was not outlined in the tripartite agreement but underscored the level of confidence both had in the opinion of a respected independent and doyen of the profession. I took that experience with me when I moved to Asia and started to work on international projects shortly thereafter.
A project neutral, whilst sharing many of the attributes, is not an expert determiner in that the opinion rendered is not normally binding and enforceable. Initiated through joint appointment with both parties, the purpose is to assist the parties in avoiding or settling a potential formal dispute through the rigour of analysis and independence of opinion to allow the project to progress and/or complete.
That role and function is now being mirrored, to a large extent, in the formal procedures set out under FIDIC 2nd Edition contracts through the DAAB, Dispute Avoidance/Adjudication Board, procedure with an emphasis on dispute avoidance through a standing board.
The advent of statutory adjudication, in its various forms in different countries, may be seen to diminish the utility of the project neutral approach in those jurisdictions unless parties have a genuine incentive to engage in a collaborative solution; where that is the case it has much to recommend it.
What short and long-term affects do you see covid-19 having on the construction industry?
Covid-19 and the restrictions that come with operating on site through imposed social distancing are, as for all businesses, likely to be around until an effective vaccine can be rolled out.
For existing contracts, imposing that new operational requirement will clearly bring discussion around who bears the time and cost implications and what mitigation measure, if any, are available or to be deployed.
Couple that with the complete shutdown of work on site for a number of months and you have the requirement to start up, effectively, suspended projects and the additional cost and loss of productivity that entails together with training and familiarity in new requirements/procedures alongside what will be a lower productivity norm on the job as a consequence of those more restrictive social distancing or PPE operational requirements.
Working through those issues under differing legal implementation approaches adopted, even just within the UK, and contract structures applying to construction projects, coupled with the costs and losses arising in a sector renowned for low margins, is likely to see an increase in determinative dispute resolution.
For new projects going forward, the requirements to address the covid-19 new normal is likely to be written into the contract requirements and the risks/costs associated with that in terms of time and money attributed to one of the parties under the contract-as was seen immediately after SARS and MERS.
What do you think will be the greatest challenges facing construction experts over the next five years and how will you ensure you are prepared to face them?
Mastering increasingly large multisource datasets that are being generated on site and in connection with projects that form the contemporaneous factual project record will be a growing challenge for experts.
Today it is not uncommon to be presented with terabytes of unstructured data from clients or through disclosure; I have seen expert reports used as a strategic vehicle to introduce huge amounts of ‘new’ and unreferenced material at a late stage into a procedure. The expert opposite being left with a matter of weeks before the meeting of experts and response reports to somehow analyse, absorb and form an opinion around that material before being in a position to meaningfully engage with the other expert. Even if tribunals are sympathetic to the plight of the expert on the receiving end of that, procedural timetables and tribunal/party calendars are often such that there is little flexibility in adjusting submission deadlines.
Even without the abusive scenario above exacerbating the issue, the magnitude of project data, captured and communicated across multiple platforms and in varying media requires a full mastery and marshalling of that factual material in context and across the timeframe of the issues under discussion. Whilst there are many analytical tools that can assist in cutting across the volume of data and experts may use specialised assistants to narrow that material, the expert remains responsible for that structured analysis and the opinion proffered in respect of the outcome of the analysis and the issue in question. As such, it is important that the expert is familiar with how those tools operate, any issues or bias inherent in their application and how, or if, that may skew to outcome of those material searches/analysis — the expert cannot rely upon a black box approach of “the computer said” — that does not assist the tribunal and does not satisfy the remit of the expert.
