Bhogapuram Airport, located approximately 50 kilometers from Visakhapatnam Airport, is a pivotal infrastructure project aimed at improving regional connectivity and meeting the increasing demand for passenger services. Spanning 2,203 acres, the airport is designed to handle an annual capacity of 6 million passengers (MPPA) upon completion. The project entails the engineering, procurement, and construction of a 77,500-square-meter Passenger Terminal Building, a 55-meter-high Air Traffic Control (ATC) Tower, and supporting infrastructure that includes 23 ancillary buildings. The master plan also features the creation of a landscaped area covering 2.6 lakh square meters, a 3.8-kilometer-long runway, and comprehensive airside facilities, such as taxiways, aprons, and advanced ground-handling systems to ensure efficient operations.
The scope of work encompasses design, procurement, and execution, including structural steel construction, roofing, and sheeting. It also involves the integration of mechanical, electrical, and plumbing (MEP) systems, along with high-quality finishes, facade, Vertical and Horizontal Transport (VHT) systems, and a baggage handling system. Scheduled for completion in 33 months, this transformative project is set to serve as a modern gateway for the region, driving economic development and enhancing global connectivity.
Autodesk Construction Cloud has transformed our workflow, providing a seamless platform for accessing, measuring, and comparing construction drawings across revisions. Its intuitive interface and robust performance have been invaluable in enhancing collaboration and precision across our project teams.
BIM has enabled us to visualize every aspect of the design with precision before construction commencement. By leveraging the 4D model to analyse look ahead scenarios, we proactively identified potential risks and developed effective mitigation strategies well in advance, ensuring smoother project execution.
At GVIAL, Quantification is done as per Discipline, Building, Zone and Level for various activities like -
BIM provides visualization of structures and finishes in critical areas, essential for precise planning and achieving a 'first-time-right' approach. Direct quantity extraction for concrete and shuttering by zone, level, and pour has saved significant manhours, boosting team efficiency.
Using BIM for subcontractor measurement tracking has streamlined our processes by providing real-time progress insights and reducing reconciliation time. We can quickly visualize which areas are assigned and paid to each subcontractor, enhancing transparency. Quantity Take-Off through BIM has increased our accuracy and efficiency, ensuring precise resource management.
BIM through Augmented Reality simplifies complex designs through coordinated model visualization, making it very easy to understand for all stakeholders. BIM’s accurate quantification streamlines planning, procurement and progress tracking ensuring efficient decision-making and resource management.
Laser Scanning use cases at GVIAL:
External Walls as-built captured through Laser scanning. This scan enabled precise deviation analysis for external openings, including windows and facade alignment. Compared to conventional surveying methods using total stations, this approach saved significant man-days and ensured higher accuracy, making it a game-changer for project execution.
BIM Kick-off, Autodesk Construction Cloud workshop and Navisworks Workshop were conducted for Project Team from various departments – Civil, EHS, Formwork, Mechanical, MEP, Planning, QA/QC, Surveying and EDRC.
Key Outcomes of the programs:
BIM should be leveraged to empower the project execution team in their daily tasks, rather than merely fulfilling contractual requirements. At GVIAL, BIM extends far beyond visualization; Our information model actively supports progress monitoring, delay identification, quantity extraction, reconciliation, bill generation, and more.
BIM has been extensively utilized in the Bhogapuram Airport project from its inception. Beyond enabling complete project visualization and precise planning, BIM is used for Quantity Take-offs across all disciplines, coordinating interfacing services during design stages, and supporting on-site execution. It allows for weekly analysis of progress relative to the baseline schedule across all 24 buildings and external works. The BIM-extracted Quantity Take-offs, combined with status information, have streamlined both client and subcontractor billing, reducing errors and ensuring transparent communication across stakeholders. In a nutshell, BIM has proven to be an exceptionally powerful tool for project sites, and we have leveraged its full potential to achieve significant benefits in this project.
