Annual Report Highlights 2015


Focusing on essential national needs

National need:

Plasma Vitrification

With the UK’s nuclear decommissioning programme set to gather pace in the near future, the plasma vitrification project has enormous potential, both in the UK and globally. Plasma vitrification has the ability to greatly reduce the volume of ILW and ease the burden on the UK’s waste storage facilities, leading to considerable savings, both in building future storage facilities and in other areas of ILW treatment. Billions of pounds could be saved by the nuclear industry over the coming decades, with the added possibility of income through sale of the technology abroad.

I am very proud of our team of engineers from Costain and Tetronics, who are working so creatively to develop a new approach to one of the key issues in the nuclear sector: reducing the volume of nuclear waste dramatically, whilst at the same time enhancing safety and environmental performance.

Severn Trent Water

Water Treatment Works

This was a complex operation that involved the coordination of a multitude of trades and skill sets. Collaboration between Severn Trent Water, Costain, MWH, Draper Civil Engineering, Freeflow Pipe Systems, Ainscough and Cemex, meant the work went without a hitch. The team worked around the clock to ensure the connections were successfully completed first time, safely and on programme, ensuring that no one went without water in one of the UK’s biggest conurbations.

Our work on this major Water Treatment Works epitomises the excellent team ethos and good working relationship we have with Severn Trent Water. Around 30 people were involved in the work, reflecting our logistical capabilities and trusted delivery. That’s why we continue to be the partner of choice in AMP6.

National need:

Dimlington Gas Terminal

As well as ensuring compliance with the legislation, Costain’s solution increased the site’s efficiency and eliminated the need for costly plant shut-downs, estimated at £3 million/day in lost revenue at full throughput. Costain’s solution reduced the initial capital costs by over 60% and helped to retain plant flexibility for economic processing of future gas field finds. An Environment Agency compliance milestone was achieved in December 2014, and the project won Industry Project of the Year at the Institution of Chemical Engineers (IChemE) Global Awards 2015.K.

For 18 months, I was part of a highly motivated and innovative team that really wanted to create as much value as possible for the customer. I was fortunate enough to be part of the team for the entire project life‑cycle, from design to construction, and receiving such positive client feedback throughout was really encouraging for me as a graduate.

National need:

Paddington New Yard

Costain was a member of a talented and integrated delivery team, supported by specialists from across the business. As a major tier-one contractor, Costain was able to bring together the right people on the right contracts, which allowed for greater collaboration even on the biggest and most complex infrastructure projects in Europe. In total, Costain was awarded 13 Crossrail contracts.

We had to implement a number of different techniques in order to achieve the best possible outcome, without compromising on health and safety. It has been a huge achievement to hand over the Royal Oak Portal and track bed to the railway systems team.

Transport for London (TfL)

Hammersmith Flyover Refurbishment

The project team worked day and night over two years to fully restore and strengthen the 1960s flyover, extending the life of the structure by a further 60 years, saving the UK economy an estimated £101 million per annum if the flyover was out of service.

The strengthening and refurbishment of the Hammersmith Flyover was a highly complex project but the whole team rose to the challenge, safely completing the work this summer within a very tight timescale to the delight of Transport for London. I am immensely proud of what we have achieved.

National need:
Thames Water

Haslemere Water Treatment Works

Our UV solution saved in excess of £2 million in capital expenditure compared to the filtration solution in Thames Water’s business plan. By commissioning the new plant in time for the summer peak demand, the need for Thames Water to install temporary process equipment was eliminated, saving Thames Water approximately £500,000 of operational costs. The project was initially scheduled as a seven-month design and build programme, but the offsite construction method brought the delivery time down to less than five months, 30% lower than originally planned.

This project is a fantastic example of what can be achieved if you focus on innovative thinking and challenge everything you do to ensure that the output is as efficient as it possibly can be.
