Company Profile

UrbaCon is a Qatar-based construction services company with a substantial international portfolio. UrbaCon has grown to become the number one contractor in Qatar in terms of project value, and the third largest in the entire Middle East.

With resources including a near 34,000 strong workforce and over 2100 plants and machines, UrbaCon has become known for its massive construction projects. Highlights from its portfolio include the Qatar Economic Zone, the Simaisma Island Bridge, and a string of small island developments.


The Challenge

Invicta was approached by UrbaCon with the aim of protecting a car park area at the prestigious 13-15 Prince’s Gate, a Grade II listed property in the heart of London. UrbaCon felt that fire protection was needed to protect against the possibility of a kitchen extract system failing and catching fire.

Invicta had to provide a solution that would fit the protection system into an isolated small area between other services. This would sit between the underground car park and the residence, providing 4-hour fire integrity from above and below, protecting both the buildings and vehicles.


The Constraints

As well as the tight space requirements, the fire protection system would also have to avoid restricting the headroom, as the protection was above a car turntable where head height is crucial, as cars drive through this area. Alternate discreet handles would also have to be used for the demountable panels, as our standard handles encroached lower than the site could accept.


The Solution

Working with UrbaCon, Invicta designed a self-supporting Durasteel ceiling to fit within the allotted space. This included bulkhead returns to the surrounding concrete slab, as well as removable access panels located in the correct areas to enable inspections, maintenance, and routine cleaning.


The Result

The Durasteel ceiling was successfully installed by a team of just two Durasteel engineers, and completed in eight days. The system was signed off and certificated as per the client’s specification and protection requirements.
