1 EEESTA Prestige Seminar 9 th November 2011 London 2012 Olympic Park Delivery of a Time Critical Major Programme Simon Wright Director of Infrastructure and Utilities Olympic Delivery Authority

2 At the start

3 Five Clear Phases Planning (to Feb 07) The road to Beijing: making the Park 3D Dig, Demolish & Design The Big Build (to Summer 2011) Test (to Games 2012) Legacy (post 2012)

4 Procurement Approach ODA decided to remain a lean client Total budget was established following publication of the Base Line Report Delivery Partner appointed following a Competitive Dialogue through public procurement ODA remained responsible for the policies, budget, scope, business case and stakeholder management Delivery Partner was responsible for design management, risk, programme, construction management and contract administration, site logistics ODA determined that it would accept appropriate risks Contracts run on a pro-active, incentivised,collaborativebasis

5 Procurement 411 tenders run on etendering system 1457 companies have directly supplied the ODA 98% are UK companies Half are based outside London Over 1/3 are SMEs Programme is on time and within budget

6 Enabling Works Works included Bulk earthworks Geotechnical and environmental site investigations Contaminated soil remediation Invasive species treatment Utility diversions River improvements Procurement started in 2006 by LDA Procurement had to commence before design was completed Flexibility required

16 Utility Concessions ODA had raised the possibility of attracting private sector investment for utilities Government set ambitious targets A multi-utility and energy concession were tendered through OJEU Following some re-shaping of the bid Energy, High Voltage Electrical Distribution Network and Gas Pipeline concessions were successfully awarded Telecoms ducts were installed by ODA with one of the 3 banks now sold to a telecoms company

17 Energy Centre Concession Obligations/Risks 40 Years Concessionaire - The financing, design, build, operation and maintenance of all plant and equipment contained within the two Energy Centres and heating and cooling networks from the Energy Centres to each development Concessionaire - The purchase of all primary energy (fossil fuel, electricity or renewable fuel), and taking risk on input fuel price Concessionaire - The supply and sale of heating and cooling to the end-users and the sale of electricity to the grid Concessionaire Development Build Out Risk Employer - Obligation to connect to the heating network and cooling network within the Olympic Park

18 Community Energy Strategy Olympic Park Olympic Village Stratford Zones Energy Centres First Phase Capacities 120 MW Heating 45 MW Cooling 20 MW Electrical 20 km Networks

19 Kings Yard

20 Energy efficient design CCHP Biomass boilers Photovoltaic panels Micro Renewables

21 Energy Centre 3.3MWe spark ignition gas engine CHP units with 2 stage exhaust heat recovery 20MW dual fired hot water boilers 3MW biomass boilers 4MW two stage adsorption chillers 7MW electric chillers using ammonia as refigerant Open evaporation cooling towers Thermal stores -750 cu m heat and cool stores 45 m high flue tower Maximum output 120 MW heat, 16 MW cooling and 17 MW electrical

22 District Heating and Cooling Networks 16 km of heating and 2 km cooling pipework Diameter up to 700 mm Full insulation and leak detection 40 heating and 20 cooling sub-stations Flow up to 400 l/s at 6 bar initially with maximum flow up to 1000 l/s Low temperature in heating network 95 degrees C out and 55 degrees C return

25 Community Energy Networks Design Criteria Sized for legacy Optimised for life cost (capital, pumping and heat losses) Variable volume with differential pressure control Installation Preinsulated steel pipe Leak detection system Fibre network in same trench for metering/monitoring

26 High Voltage Electrical Network Site was too large for a private wire network ODA undertook the 132kV primary sub-station through a design and construct contract Tenders sought for design, own and operate of 11kV network and adoption of the 132kV substation Value of 132kV substation and future revenue enabled significant discount to be offered on network capital cost
