Peri, a leading manufacturer and supplier of formwork and scaffolding systems, said work was going as per schedule at the Abu Dhabi International Airport for the completion of the new X-shaped airport terminal being built between the north and south runways.

The Midfield Terminal Complex (MTC) is currently one of the most important construction projects in the UAE, said the German company in its statement.

On completion in 2017, the airport terminal will handle some 30 million passengers annually, supported by the world's largest baggage handling system.

Peri has provided yet another convincing performance with the construction of the Midfield Terminal at Abu Dhabi International Airport with the delivery of enormous amounts of materials at short notice as well as competent engineering for the related formwork and scaffolding planning., it stated

More than 6,000 slab tables were in continuous use at the massive project, the statement added.

The new X-shaped airport terminal is being built between the north and south runways. At the four piers of the so-called Midfield Terminal Building (MTB), 65 large aircraft up to the size of an Airbus A380 can be accommodated.

Centrepiece of the terminal is the over 50 m high terminal building, the so-called Central Processor. The seven-storey
structure features an area totalling 700,000 sq m, said Peri in its statement.

More than 12,000 construction workers are currently working in shifts around the clock while, at peak times, this increases to almost 17,000 site personnel, it added.

This is because more than 1,000 cu m of concrete must be formed every day. Once finally completed, this airport construction project will have processed 700,000 cu m of concrete and 200,000 T of steel, it stated.

In order to comply with the short construction period, Peri said its engineers were designing as well as
 supplying the formwork and scaffolding systems, and had impressed with the provision of competent engineering services and fast deliveries of huge quantities of materials.

The concept developed by them can be flexibly adapted to suit the different ground plan geometries and storey heights of the terminal complex.

At present, around 6,200 slab tables are in continuous use on the construction sites as only 18 months have been earmarked for realizing the shell of the Central Processor, said the German firm in its statement.

The Peri on-site formwork provision amount to almost 65,000 sq m, an area nearly as large as 10 football pitches. Within a very short time, over 60,000 robust stacking frames of the proven PD 8 shoring system were delivered to the jobsite.

The shoring towers are quickly and easily assembled requiring a minimum of personnel and the high loads from the floor slabs and beams are reliably and safely transferred into the ground.

The massive, mostly 0.85 m wide and 1.10 m high beams are being constructed together with the slabs in one pour. The 6 m to 10 m high PD 8 slab tables serve as the supporting structure which can be moved manually to the next section each time by means of a transportation trolley without the use of a crane, it said.

In addition to the cost-effective slab formwork concept for the floor areas, Peri engineers said they have developed a comprehensive formwork solution for walls and columns.

For realizing the total of 4,000 massive, reinforced concrete columns with 1 m to 2.50 m edge lengths – resulting in wide range of dimensions – the construction crew are using Vario GT 24 column formwork and project-related SRS circular column formwork elements, said the Peri engineers.

Furthermore, the up to 12.5 m high reinforced concrete walls are being efficiently formed with the Vario GT 24 girder wall formwork system, they added.-TradeArabia News Service
