The project officially began on October 2000. Demolition of the old structure was scheduled on December 2000 and the new stadium was expected to open in 2003. However, the project was delayed to 9th March 2007. This was because of delays caused by various factors chief among them financial and disputes related issues.
Upon completion, the one kilometre circumference Wembley Stadium was supposed to have a bowl volume of 1,139,100m3 and 90,000 sitting capacity with demountable seats. The most spectacular thing is the 1750 tonne and 133-metre tall arch that became the symbol of the stadium. Wembley Stadium has 2618 toilets, state of art conferencing and banqueting facilities as well as 103,000m2 foot print.

Other workings were 15000 steel reinforcements, 21,000 sprinkler heads and 1720 km small power and lighting. However, it was not possible to develop retractable new roof of the stadium and fans became disappointed.
The work was quite satisfactory as most specification in the contract was met despite the delay occasioned by factors beyond the construction Company. Multiplex Construction Company made £70 million over budget.
The planned cost of the total project was £798 million. However, Multiplex was later paid a total of £834 million indicating project variance cost of £36million. There are many reasons that explain the delays and increase in the project cost of Wembley Stadium. The delays caused millions of losses in pounds to the Wembley National Stadium Limited, Multiplex and other outsourcing companies such as Cleveland Bridge (steel contractor) and PC Harrington (concrete contractor). Wembley National Stadium Limited paid additional £36m to the Multiplex (WNSL 2010). In addition, the
