The list of recent engineering marvels in the UK air travel sector should perhaps mention expansion as a major project. Heathrow Airport's mega infrastructure status, involving the Terminal 5 project, aimed to increase the airport's capacity to reach the 35 million passenger threshold per year. Built before current air travel engineering and related technologies, Heathrow has been transformed piecemeal over the years, to overcome the hurdle of managing air travel demand. As Brady and Davies (2010) noted, over the years the airport has found it inevitable to host larger aircraft models, testaments to this age and civilisation. “This was a megaproject that was on time and on budget from the start of construction, bucking all trends in previous megaprojects…” (Brady and Davies 2010, p. 151) In terms of innovation, the Most of the project included several innovative construction and safety systems compliant with the best global standards. Valued at £4.3 billion, the scale and 19-year duration of the Terminal 5 project exceeded normal mega projects, making the project one of the largest in any sector (Brady and Davies 2010). Some of the project's areas of improvement targeting the travel experience included the following innovative components. According to Coop et al. (2007), Heathrow's Terminal 5 mega project was to incorporate a huge runway reconstruction component for improved traffic management. Using modern technology, construction required advanced assessment of the runway foundations to ensure long-lasting engineering works. Perhaps the most notable innovation noted by the authors concerns the investigation of the stability characteristics of the track, through elaborate tests... middle of paper... the allocated budget but also the saving of public money. “T5 is already a testament to the skill and hard work of thousands of people, including architects, planners, construction workers, airport and airline staff, who together made the building a reality,” (Brady and Davies 2010, p. 152). As mentioned, the involvement of government agencies and the country's highest office facilitated security in securing the financing needs of the megaproject (Fugeman et al. 2008). By involving efficient integrated management systems, the T5 project has delivered savings of up to £200 million. The integration of every component of the project ensured that nearly every component was delivered on time, with only a small fraction of incompleteness reported at launch. When obstacles arose, the T5 integration score allowed management to regain control of the airport's operations within hours.
