Next Generation Smart Contracts – Improving Temporal Specificity

We are pleased to announce that following on from the supply chain school workshop in 2019, a research paper on Improving Temporal Specificity written by Associate Professor Chris Clack and Alan Midgely was presented by Chris at UCL’s CBT Research Showcase on February 20th 2020.

The construction industry contributes approximately £117 billion or six per cent to the UK economy[1], and Infrastructure contributes a further one to two per cent[2]. However, both industries are hampered by low productivity[3], unpredictability[4] and a strongly ingrained adversarial culture[5]. One consequence of this friction is lifecycle contract management which is estimated to contribute 10% of the project costs. Continue Reading

The Golden Thread of Responsibility


Professor David Mosey Director, Centre of Construction Law and Dispute Resolution at King’s College London has produced the third in a series of Videos on FAC1 and collaborative working. 

This video explores how Futures Housing Group has used the FAC-1 framework alliance contract to combine agreed cost savings with new opportunities for small local contractors and more integrated support for their residents. We also hear the Housing Forum’s assessment of FAC-1 as a means to deliver improved safety and social value.

DLT in Construction 2

We are pleased to highlight that Alan was invited to chair the second of the Supply Chain Schools events on DLT in Construction on Thursday 21 March 2019.

Feedback from Wilmott Dixon on the session:

Great morning with Action Sustainability [supply chain school] and a few experts from the hashtagblockchain world exploring, discussing and hashtagdebating emerging applications in the built hashtagenvironment sector. I’ve been actively seeking practical applications for some time and believe today’s conversation has helped me turn a corner. hashtaginsightshashtaglearninghashtagapplicationhashtaginnovation

At this session, we were fortunate to have the support of experts in DLT.
Dr Barry Childe, Damian Kozak and David Michael shared their experience of DLT in Banking and Finance, while Matt Colmer presented his findings from the research work of Digital Catapult and the Institute of Civil Engineers. Alan delivered a presentation on the risks and opportunities of DLT for the construction industry, as well as facilitating a workshop that brought together the various views of the audience and speakers. Alan’s review identified poor payment practices as an ongoing problem in the industry, which DLT could address. Furthermore, he focused on the relationships between multiple stakeholders, scope change across the project cycle and multiple platforms as exacerbating the problem. Therefore, the workshop looked at combining the work stages in the RIBA plan of work, with the contract matrix and DLT to streamline data flows:


Sir Michael Latham’s report* identified that It is absolutely fundamental to trust within the construction industry that participants should be paid for the work which they have undertaken… The report also recommended a ban on “pay when paid”  and Mandatory trust funds for payments.

One of the biggest changes to the industry that arose from these enquiries was the introduction of the Construction Act, which underpins Statutory Adjudication.

However and as we know from the collapse of Carillion, late payment remains a problem in the industry. DLT has been used to streamline commercial transactions in other sectors, perhaps its time to bring this knowledge to Construction…

Constructing, A.Blockchain

Blockchain – what does it mean for construction?

Supply chain school

Alan helped to coordinate, and delivered a speech at, a conference on Blockchain in the construction industry. The event was coordinated by ActionSustainability’s supply chain school  which provided with the following outputs:

  • Attendees received insight and understanding of Blockchain technology and its potential application in construction supply chains – especially linked to advancing sustainable construction outcomes.
  • The speakers shared their experience of what is currently happening in relation to Blockchain technology in our industry.
  • They also shared experiences and lessons learned of early adopters of Blockchain tech.
  • Inspiring more conversations about the technology within the industry, and how it can be used to drive better construction and social outcomes.

Feedback from the event “…was very good and it was good to see that our partners and members are keen to explore the opportunities that DLT’s present in more depth…

We are pleased to note that expert evidence provided by Alan for an adjudication in May 2018 was instrumental in the Adjudicators decision to award in favor of his client.

In particular he received the following commendations:

Had a chance to look over the decision….I read a pleasing amount of “I agree with Mr Midgley.” I was also happy to note no sign whatsoever of any agreement with [the other expert] !” – Hardwicke Chambers, Barristers.

I am delighted to inform you that the adjudicator (on adjudication 1) has reached his decision and agreed with pretty much every point we have made.” – Pennington Manches, Solicitors.

What really happened at Carillion?

For those who are interested in the facts, the attached parliamentary report should make an interesting read.

Parliamentary report into the collapse of Carillion

…When dividends are paid on the basis of expected profits, the company is effectively borrowing money to pay its shareholders…

…In the five years from 2012 to 2016, Carillion paid out £217 million more in dividends than it generated in cash from its operations…

Carillion: Retention Title Vesting Clauses – Do they provide security over goods ?

This July 2016 SCL paper by Michael Mendelblat, may make an interesting read for those facing a dispute over goods or materials on site, the ownership of which has come into question as a consequence of the recent and unfortunate demise of Carillion.
