Heathrow third runway timeline: 2015-2028

Charting Heathrow’s third runway from its backing by the Airports Commission to its parliamentary approval – and what comes next for the project.

July 2015

The government approves Heathrow’s third runway expansion, leading Richmond Park’s MP Zac Goldsmith (pictured) to resign in protest.

December 2016

Heathrow chooses seven companies to design its expansion, as exclusively revealed by Construction News. Amec Foster Wheeler, Arup, Atkins, Grimshaw, Mott MacDonald, Jacobs and Quod will be known as the integrated design team and are each awarded four-year contracts.

February 2017

The government publishes a draft National Policy Statement (NPS), for which a 16-week public consultation gets under way. The NPS sets out regulations that Heathrow must comply with to get a development consent order (DCO).

April 2017

Heathrow begins the hunt for locations to host four construction hubs – and for the construction firms to deliver them. The hubs will be responsible for preassembling and consolidating components for the expansion before they are transported to the airport.

May 2017

The government’s 16-week public consultation ends, having garnered 72,239 responses.

July 2017

Hotel operator Arora Group, one of the largest landowners at Heathrow, submits alternative proposals for the airport’s expansion to the Department of Transport that it claims would reduce costs by £6.7bn. It suggests cutting back on terminal design and taxi systems; reducing the site area by 20 per cent; axing the terminal 2 expansion; eliminating the passenger transport systems; and moving the runway so it no longer impacts the M4 and M25 (pictured).

July 2017

Heathrow scraps proposals for a new terminal to lower costs. Instead, it will invest in extending terminals 2 and 5 phasing its work over a 20-year period. Plans for baggage facilities and an underground train are also omitted from the expansion proposals within the airport’s half-year results.

October 2017

The new draft of the government’s NPS and the public’s responses are published. The new NPS states Heathrow must introduce six more domestic air routes by 2030; more support for affected communities; legally binding noise targets; and increased payments to local homeowners. The NPS states that a second runway at Gatwick would cause less environmental damage. Public consultation on the revised draft begins.

November 2017

National Infrastructure Commission chairman Lord Adonis describes the impact of delays to Heathrow as “sacrificing national wellbeing… We have to get on and do it”.

November 2017

Heathrow reveals the 65 companies and local councils on the shortlist to be involved in delivering the offsite hubs, including Balfour Beatty and Laing O’Rourke.

The public consultation on the NPS draft closes on 19 December.
