Heathrow Airport Limited (HAL) and Arora Group\u2019s Heathrow West Limited (HWL) have been competing for the lucrative third runway expansion plans contract since the summer, when HWL announced their slightly cheaper(but smaller in scale) plans<\/a>.<\/p>\n The question of building around the M25 has long plagued plans to expand Heathrow with a third runway northwest of the airport. HWL’s plans largely avoided extensive works through shortening the length of the new runway and using an ‘outside-in’ phasing approach, which would reduce the footprint of construction works over time. This was estimated to cost under \u00a325bn, though the plans did not include the redevelopment of the airport’s existing central area.<\/p>\n HAL’s \u00a333bn proposal will realign the motorway underneath the new runway, at a cost of \u00a31.5bn. The plans include an additional \u00a312bn of associated terminal infrastructure, as well as the \u00a321bn for the actual runway construction. The airport also intends \u00a315bn of investment into existing airport facilities for upgrades and modernisation, which will go ahead regardless of the final planning decision on a third runway. These works will make an estimated total of \u00a333bn.<\/p>\n This proposal will influence the review of the Airports National Policy Statement (ANPS)<\/a> framework, where the planning decision on expansion at the airport will be made. The government is now expecting an application for development consent next year.<\/p>\nHeathrow versus Arora<\/h3>\n
