Al Hamra Business Tower was designed by the US based architects SOM who had set very high standards and quality with their designs incorporated with their quality and demanding specifications, during the tender stage it was up to the architects to decide the best elevator company that will be able to exceed the standards and deliver in a timely manner.
Al Hamra project was exceptional with its design and transportation system that were both complex. The designer had put many criteria's in place one being the speed at which the elevators travelled per floor and the capacity that were both unavailable in Hitachi’s product range.
To ensure the effectiveness of the elevators that were to be accomplished it was necessary that the engineers of Al Hamra tower take into consideration the elevators through all the prior phases finalizing the construction of the tower. Achieving the required specifications and installation techniques of the unique high rise elevators were the most challenging.
Alhamra tower architects faced challenges of designing a building with minimum spaces in order to accommodate the big number of lifts yet not to disturb the offices area and they had put in place many criteria’s in mind one being the speed at which the elevators will travel per floor and the capacity due to Al Hamra complex vertical transportation system which came from the building’s unique design.

The ultra-high speed elevators had immense motors weighing 18 tons each and the team were faced with a challenge of hoisting the heavy motors to their final locations in the machine rooms at top of the building because the buildings’ tower crane was not prepared to lift such a high capacity. Hitachi was faced with having to come up with a technique that will assist in lifting these heavy motors to the top of the tower in a timely manner in order to complete the elevators project on time.
During the tender stage, several models of customized lifts were required by the customer but were not available, as well as specs required (in terms of load and speed) that were out of Hitachi’s production range. It was also the first time for Hitachi and Ahmadiah to install, design and test these customized elevators. Hitachi and Ahmadiah had to find a solution to develop new models of elevators that can travel at a high speed of 10meters per second.
Achieving the required specifications and installation techniques of the most distinctive high rise elevators were the most challenging as it was necessary to generate new approaches for the alignments of the rails to assure in the speedy travels

Additionally, there were heavy tower transformers that were (weighing 10 tons each) and were located at one of the upper floors. Needing to lift these transformers to their final location and potential replacement later on the project the consultant required this process to be done through one of the tower service elevators; that is with a load of 4500kg and the speed of 6m/s. Hitachi was faced with this lifting challenge and was able to solve it through effective communications and problem solving methods with Ahmadiah.
