Khalifa Ports and Industrial Zone

Project Summary

Khalifa Port and Industrial Zone Abu Dhabi is one of the world’s largest greenfield development projects as well as one of the world’s largest combined port and industrial zone developments. It is an integral part of Abu Dhabi’s vision of sustainable economic growth in the United Arab Emirates (UAE).  The industrial zone is located almost equidistant to Abu Dhabi and Dubai, with extended frontage along the E11 Highway connecting the two cities.

Habtoor Leighton Group was proud to secure the project. Scope of work includes the onshore civil and building package for the Khalifa Port and Industrial Zone. As a design and construction project, the works included around 40 buildings ranging from single guard houses to the 80,0000 square metre central facilities, to civil engineering infrastructure works such as 18km of 4 -and 6-lane expressway, 38 RCC culverts, 2 interchanges with entry and exit ramps, 2 railway bridges, and 11kV/33kV networking. Other utilities such as combined waste water, potable water, groundwater, stormwater, process water and services are also included, as are associated infrastructure works consisting of a series of road networks, bridges, utility installations, containment structures, reinforced earth embankments, patrol roads, an exterior maintenance system, MEP works, building detailing, signage, hard and soft landscaping, and maintenance.

The Challenge

This complex project involved design issues such as road top level clashes with existing utilities, bridges, culverts, and the deck top level. Most of the road profiles the team used were revised as per site condition. At the project’s outset, it seemed there would not even be enough time for them to design profiles and work out these issues before the milestone.

The Solution

With the help of 12d Model software, though, the Leighton team did achieve success in this project.
They raised the levels on the profile as necessary, edited super alignments by string, and changed the vertical intersection points from the vertical IP properties. They also input all the data such as IP chainages, vertical curve length, and ‘click to set’, by which 12d Model automatically regenerated the vertical profile and automatically set the k values and radius as required, giving the ability to change the profile of roads as per the control line.
Next, they edited their design models and retriangulates TINs as per the new controls, then uploaded to the millimetre GPS in asphalt paver, by which they were able to smoothly pave asphalt with the required thickness above the concrete deck.
In addition to assisting design, 12d Model helped the team to minimise their required survey crew, as they did not need to fix any Line/Levels on the pavement work. Once they created models, they were able to upload these to the machines (graders, bull dozers, etc.) so that a single operator could finished the grading work both quantitatively and qualitatively.
12d Model also helped the team to prepare conformance reports, plotting the topographic survey in a short time and with attractive presentation.

Result

The Leighton team found 12d Model to be a very efficient and useful software product to help them save a great deal of money by reducing manpower and time, and helping them finish their project ahead of schedule.
