This research presents an integrated quantitative framework for developing sustainable airport airside infrastructure by integrating Building Information Modeling with Geographic Information Systems, the use of smart construction equipment and sustainable pavement material technologies, alongside evaluating the environmental and economic impacts of carbon emission reduction strategies during the construction phase, aiming to reduce Greenhouse Gas Emissions (Scope1).The methodological scope comprises three main pillars: The first focuses on leveraging Building Information Modeling and Geographic Information System to achieve an optimal cut -and -fill balance within the airport boundary and the deployment of equipment guided by 3D GPS technology and Artificial Intelligence during the execution of excavation, backfilling and fine grading of the subgrade, as well as during the spreading of the subbase course and base course, achieving a high level of elevation accuracy ranging between ±3: ±5 mm.The second pillar involves using Warm Mix Asphalt in paving, produced via mechanical water injection to lower mixing temperature by 20: 40 °C.The third pillar focuses on capturing carbon dioxide and reinjecting it into fresh concrete during central mixing, a processing called carbon mineralization.Using equipment's guided by 3D GPS technology and Artificial Intelligence reduces directly equipment operating hours by 30: 50% during earthworks, subgrade / base layer preparation and fine grading.Carbon mineralization is using in rigid paving for runway thresholds and aircraft aprons, this technology permanently sequesters carbon as calcium carbonate, boosting the concrete's early compressive strength and reduces cement consumption.As a baseline model, assuming 1000 direct equipment operation hours, this reduction yields a direct fuel savings 10000 liters of diesel, which translates to a direct fuel cost reduction of $10000.Cumulative operational savings reach $ 24000 including labor and maintenance, while abating 26.8 tCO2 e in scope1 emissions.Concurrently, Warm Mix Asphalt cuts plant burner fuel consumption by 20 % and reduces site level volatile organic compounds by 50%.Regarding carbon mineralization technology, it permanently sequesters up to 15kgCO2/m3 in concrete pavement without compromising structural integrity or flexural strength under heavy aircraft gear loadings.Consequently, the approach presented in this study offers airfield infrastructure engineers and aviation authorities a validated, scalable pathway toward achieving carbon neutrality during airside infrastructure construction.
