Participants of our Global BIM Management for Infrastructure Projects Certification Program have the unique opportunity for an on-site visit to the Abu Dhabi International Airport Midfield Terminal Building (MTB-ADIA). This site visit gives participants the chance to apply the material learned within the course in a practical way, by relating it directly to this mega project based on what has been estimated to be the largest and most comprehensive BIM model ever created. In this three-part article, we will give an in-depth look at the project, including the project requirements, pre-award preparations and tender, electronic data interchange and the difficulties and challenges faced within the project.
The Midfield Terminal Building of the Abu Dhabi Airport (MTB-ADIA) is a $3 billion, 700,000 square-meter development, providing a terminal building with passenger and cargo facilities, duty-free shops and restaurants for a total capacity of 27-40 million people per year. The unique X-shaped building will be located between the two existing runways, hence the name ‘Midfield’.
Designed to render an open and spacious environment, the Midfield Terminal Building features large column-free zones with inclined steel arches supporting the soaring roof. A large hall leads passengers to the center of the building, which contains a hotel, lounges, cultural outlets, stores and a park-like garden.
Guided by environmental objectives, the Midfield Terminal Building is designed to meet the UAE’s Two Pearl Rating for Sustainable Design. Towards this goal, the terminal limits the use of potable water by incorporating dry climate landscaping and uses low energy lighting supplemented by daylight, filtered through the transparent walls.
The project is challenging in terms of engineering, construction and procurement due to the unique nature of the design and the inherent complexities of its operation. Anticipating the challenges that such complexities posed the owner, Abu Dhabi Airport Companies (ADAC), sought to promote technologies that would facilitate the delivery of the project and enhance its operation throughout its lifecycle. One such initiative was the requirement for BIM-integrated processes. This was enforced by a set of demanding, ambitious and quite unique specifications.
BIM Specifications at the Tender Phase
Project tender requirements stipulated that the general contractor must develop, communicate and share a comprehensive BIM for all disciplines, involving all sub-contractors’ and manufacturers’ scope. The BIM Implementation, therefore, had to cover engineering and design (clash mitigation, design coordination, an RFI [Request for Information] system, shop drawings), project controls and planning (scheduling, cost estimation, progress, and 4D studies), contractual and quantity surveying (quantity take-off and measurements) and manufacturing (digital fabrication). Site logistics, temporary installation, scaffolding, and formwork were also to be BIM-driven.
The client invited five major international Joint Venture (JV) Consortia to bid for the construction contract of the Midfield Terminal Building project. The JV of Consolidated Contractors Company (CCC), Arabtec and TAV developed an approach based largely on the experience and expertise developed in-house by CCC over the past decades. CCC’s accomplishments in this field are recognized by its peers and reputed manufacturers of BIM software. Their BIM processes were developed entirely in-house, building on the needs of their core business and the control systems that had been established within the company.
