Midfield Terminal Building Abu Dhabi International Airport
Consollidated Contractors Company’s (CCC) design and construction of the Midfield Terminal Building – a USD 3.2 billion, 750,000 square-foot terminal building for the Abu Dhabi International Airport – had to be achieved as a totally BIM-driven lifecycle to facilitate project delivery. The BIM implementation included engineering and design, project controls and planning contractual and quantity surveying, manufacturing, site logistics, and installation. The new terminal required 69,000 tons of steel, over 680,000 m3 of concrete, 360,000 m3 of suspended ceilings, and 325,000 m2 of natural stone flooring.
CCC leveraged its 17 years of experience with Bentley BIM offerings to integrate Bentley products with its in-house platforms. In addition to Bentley’s structural, architectural, mechanical, and electrical design software, CCC used AECOsim Building Designer, MicroStation VBA, ProjectWise, InRoads, and Bentley Navigator. The client, stakeholders, subcontractors, and nearly all joint venture team departments and disciplines had access to Bentley technology or benefited from the services of the joint venture’s BIM department.
Using a BIM-driven design process facilitated the delivery of the project through the entire project lifecycle – and ultimately minimized risk and ensured success. The benefits of BIM extended to construction as well. For example, leveraging information in ProjectWise, the construction team could accurately forecast construction schedules, perform logistics studies, and validate resource requirements. 4D BIM models were used to accurately forecast the time needed to complete tasks so construction teams could coordinate resources and contractors.
ProjectWise was used to store all project information, as well as manage, secure, and efficiently distribute it to all stakeholders. Through integration with other software, this data drove all other BIM processes. For example, using AECOSim Building Designer for 3D modeling, stakeholders performed highly accurate material take-offs using data embedded in 3D models. Similarly, using AECOsim Building Designer and Bentley Navigator, teams could pull data from files in ProjectWise and perform automated clash detection and design coordination.
- Using a 4D BIM model, CCC validated a tower crane resource study and found that only 20% of the proposed new crane capacity would be used, which helped CCC avoid the cost of new cranes by reallocating existing cranes to meet needs.
- CCC simplified handoffs and reduced the cycle of critical RFIs from 28 days down to two to seven days.
- Automated clash detection greatly reduced costs and man-hours – in one case, it saved CCC US $5 million and 900 hours by eliminating one major clash.
