Crossrail awards £1.25 billion NEC3 tunnelling contracts


SIMON FULLALOVE EDITOR


Transport for London’s Crossrail project awarded three major tunnelling contracts worth £1.25 billion under the NEC3 Engineering and Construction Contract (ECC) option C (target contract with activity schedule) in December 2010. The largest of these for the eastern running


The £68 million ECC-procured Velodrome is the first venue to be completed at the London 2012 Olympic Park


The NEC3-procured 6000-seat Velodrome for the London 2012 Olympic and Paralympic Games was completed in February 2011. It is the first major venue to be completed at the Olympic Park in London. The £68 million permanent venue was


completed ahead of programme and to budget by contractor ISG for the Olympic Delivery Authority (ODA). Like all other major London 2012 venues, it was procured under an NEC3 Engineering and Construction Contract option C (target contract with activity schedule).


Most energy-efficient venue The dramatic structure features a 12 000 m2


double-curvature cable-net roof, red cedar external wall cladding and a 250 m International Cycling Union approved cycling track made from Siberian pine. It is the most energy-efficient venue in the Olympic Park, achieving a 31% improvement over 2006 Building Regulations part L requirements. The compact design minimises heated air


volume and extensive use is made of natural ventilation and lighting. Potable water demand has also been reduced 73% by installing rainwater harvesting and low-water sanitary ware. The design team of Hopkins Architects,


Expedition Engineering and service engineer BDSP also sought to minimise the amount of construction material used through a detailed value engineering exercise. This resulted in ISG developing a lightweight 30 kg/m2


cable-


net system, which saved 1000 t of steelwork and reduced the size and depth of foundations.


Reasons for selection of NEC3 According to ODA deputy head of procurement


John Fernau, ‘The NEC3 Engineering and Construction Contract was selected for procuring the Velodrome and other London 2012 venues as it provides a collaborative approach supporting timely delivery, which was fundamental to ODA. There is full visibility of costs supporting effective programme budget management, and full visibility for assessing the impact of change, for example as designs were developed. ‘The contracts provide a prescribed


methodology for project management, with processes and procedures to manage delivery and support a standardised contract management approach. They also have a proven record of use and understanding within the supply chain, in contrast to potential market uncertainty over any new ODA bespoke contract.’ ODA made a number of enhancements to the


contract to support its policy ambitions, including enhanced payment terms (18 days), enhanced dispute-avoidance provisions, which include the use of an ODA appointed independent disputes avoidance panel, sub-contract provisions including the use of competitive tendering and flow-down of other policy requirements, and changes to insurance clauses reflecting ODA’s use of project insurance.●

tunnels, worth over £500 million, went to a joint venture of Dragados and John Sisk. A joint venture of Bam Nuttall, Ferrovial Agroman and Kier Construction won a combined contract for the western running tunnels and station tunnels, also worth £500 million. The third contract for the eastern station tunnels was awarded to a joint venture of Balfour Beatty, Vinci and Morgan Sindall.


Europe’s largest project With an estimated total cost of £14.5 billion


and a peak workforce of 14 000 people by 2013, Crossrail is Europe’s largest construction project and the biggest ever to be procured by NEC3 contracts. Work started in May 2009 and is due for completion in 2018. The central section through London


includes 21 km of new twin-bore rail tunnels, eight new sub-surface stations, shafts for ventilation and escape, provision of all necessary railway systems and a mainline train fleet allowing 58 peak-period services along its overall 118 km route. NEC3 contracts are being used to procure all central section works and systems requirements. Over 20 more major ECC contracts will


be awarded in 2011 and 2012, including £1.5 billion for the six central stations.


Full range of NEC3 contracts As reported by NEC Users’ Group chairman


Steve Rowsell in issue 49, a full range of NEC3 contracts are already being used on the project. Programme partner Transcend – a joint


venture of Aecom, CH2M Hill and Nichols Group – is engaged under a £100 million NEC3 Professional Service Contract (PSC), and project delivery partner Bechtel is similarly engaged under a PSC worth £400 million. Design framework agreements totalling


£300 million have been secured by 12 engineering consultancies, along with enabling works framework agreements with 17 contractors worth £350 million. All of these are based on the NEC3 Framework Contract.●
