That took a lot of coordination from other GTAA teams and the airlines, Payter remarks. To minimize impact to flight operations, Dufferin worked closely with GTAA Operations to ensure critical surfaces remained available throughout the runway and taxiway work. The phasing plan required tactical steps to swiftly follow one another along specific sections of the runway, often with multiple construction disciplines operating at the same time. It almost resembled an assembly line, Goddard recalls. You saw the demolition process start and then all the rebuild processes were happening behind it. You could see all processes of the operation happening all at once within a 750- to 1,000-meter stretch. It was pretty cool. Crews worked simultaneously on material removal, subgrade preparation, cement-stabilized base and concrete installation, asphalt paving and electrical work. Construction began April 4, 2022, and was completed Nov. 18, 2022. We used every one of these days, Payter remarks.When estimating capacity for various phases, GTAA project teams factored in the potential for bad weather, but crews ultimately enjoyed favorable work conditions for more than seven months. It is unusual for a project of this magnitude to be completed in one construction season,The Airports Authority strategically reduced runway slots during construction.
