Could Blockchain prevent the next Carillion?


Could Blockchain prevent the next Carillion?


The construction industry has gone through a lot of changes in the ten years I have been recruiting across it, yet in many ways, it has also has stayed the same. A lot of the technical innovations that have been implemented within the industry are using software to speed up processes that were done by hand (or mind) previously. For example, CAD has added a number of iterations, rather than just alter the way that we work. Also one of the recent challenges in BIM implementation is that clients are often thought not to realise the full benefits of it other than it being mandatory. With the recent Winfield Rock report[1] highlighting the issues legal professions have in understanding BIM Level 2 and “what that actually means in terms of parties’ obligations, rights and deliverables”.

Could the industry use digital engineering to truly change the nature of collaboration between clients, consultants, main contractors and sub-contractors with a technology such as Blockchain being used to independently control the flow of information across a project? For those of you who are not familiar with Blockchain it's summarised by Wikipedia rather well;

"A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a cryptographic hash of the previous block, a timestamp and transaction data.By design, a blockchain is inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way".For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority."

Whilst I am not suggesting that cryptocurrencies be used as a viable way of arranging project finance, by using the underlying technology systems could be put in place to authorise transactions once work is completed and avoid multiple intermediaries on a project. It would also provide a transparency on costs and progress to a client throughout the programme.

Some of the fallout from the collapse of Carillion, particularly from non-industry commentators such as MPs, were questions around the payment terms to contractors and the high level of risk on projects, something which often isn’t in the interest of the end client. A system where funds are held centrally and released on verification of work could prevent both main contractors being withheld funds from clients and main contractors withholding funds from sub-contractors etc. The use of peer-to-peer networks could also help real-time decision making and help increase liability between parties in the event of adverse weather, commodity price changes or other unexpected events due to the open and trustworthy information available across the system. For consultants, it can also help reduce the disconnect between design and construction throughout a project.

I would be interested in any thoughts on whether the recent events could create an impetus to create real change in the industry, would Clients embrace a new methodology and reward it at the bid stage now that we are starting to have the tools to do so?


DominicI joined Mattinson Partnership in 2014 after completing a BSc in Geography from Aberystwyth University. Over the last 3 and a half years with the business I have become a Team Leader whilst developing the Construction & Real Estate sector - placing professionals across Health & Safety, Building Surveying, Quantity Surveying, Project Management, Valuations, Development and Land. Outside of work I enjoy going to art galleries and film events, as well as using all of my annual leave to climb up mountains in Africa and travel around Southern India and Europe.

London Wildlife Trust.

We are proud partners of The London Wildlife Trust, a charity dedicated to protecting the wildlife and wild spaces of London by driving environmental projects throughout the city. Our team often get involved at ground level in Wild Workdays by helping to maintain and restore treasured spaces and land… we love to get our hands dirty! We also run multiple interactive workshops, providing their conservation trainees with invaluable career advice and insights into the environmental sector to prepare them for employment. Most recently, we worked with young people taking part in their Keeping it Wild programme, which engages young people from backgrounds currently under-represented in nature conservation.

Royal Town Planning Institute.

The RTPI represents planning professionals in the UK and Ireland and aims to encourage the development of vibrant and prosperous places and communities. Our Senior Consultant Freddie enthusiastically attends the annual Planning Convention, and we host several events throughout the year to show our support, including drinks networking and a literal pub quiz. We also keep in close contact with our friends down under, at the Planning Institute Australia and New Zealand Planning Institute. In addition, we sponsor the London Planning Summit, an event designed to address the biggest challenges facing the industry. This is our opportunity to stay on top of the latest changes in town planning by meeting with other key professionals in the sector, while celebrating our achievements.

Land Securities Group Plc.

One of our clients, LandSec, are the clever people behind Girls Can Do It Too, an initiative designed to encourage girls to consider a career in construction. Currently, only 11% of the construction workforce are female, and LandSec are attempting to increase this number by providing education and engagement projects and workshops for girls aged 11-13. Featuring workshops on demolition and tower building, as well as challenging the girls to design a planning project of their own (with a focus on budgeting and environmental considerations), LandSec have proven their dedication to addressing the need for diversity in this very male dominated industry. Ruth assists the project by sharing her fascinating insights into the industry and is even on the project judging panel!

Urban Land Institute.

In partnership with Urban Land Institute we are able to play an imperative role in creating a larger and more diverse pool of candidates within the planning & property professions. Working in schools we take part in the Urban Plan Educational workshops programme, which has now reached more than 2,500 pupils in 100 schools since its launch. Alongside more than 200 industry volunteers engaged across the country, we provide invaluable industry & careers advice to students while guiding them through their workshops and helping judge their presentations.

Carbon Footprint.

Carbon FootprintTM works to help organisations offset their CO2 through tree planting and community projects worldwide. By partnering with Carbon FootprintTM, we have planted native trees and shrubs such as Whitebeam, Hazel, Field Maple, Silver Birch, Rowan, Beech, Blackthorn, Holly and Dog Rose to create a Mattinson Forest that spreads across South East England. Carbon FootprintTM work in conjunction with the Florestal Santa Maria Project (FSM-Redd Project), designed to reduce deforestation in the Amazonian Rainforest. So, for every tree we plant in the UK we guarantee a tonne of CO₂ offset in Brazil too. Carbon FootprintTM have allowed us to not only do our bit for the environment but also commemorate moments of growth for our clients and candidates.
