On form: How formwork projects are pouring in across the region

1/7/06:

formwork contractors are casing the best deals as mega-tower construction demands the latest technology
Last year turned out to be a bumper one for those involved in the formwork industry.

A clutch of high-profile GCC jobs, from shopping malls and hospitals to super-high residential towers, has kept the local and international formwork suppliers busy. And this year looks set to offer more of the same.

Aluma Systems has seen a rise in demand for its big Flying Tables: “Our speciality is high-rise, so Dubai is a prime target for us,” says Bob O’Riordan, regional sales director, Aluma Systems (Middle East).

“With this system we can create the lightest, strongest and largest flying tables that can be manufactured by any formworks supplier — no one else can match it for size, weight or strength,” he adds.

According to O’Riordan, much of this is attributable to the unique manufacture and design of Aluma’s tables: “We believe we are the only ones to use a lightweight aluminium truss, so we’ve brought into the marketplace a new innovation to the traditional method of casting in-situ concrete slabs.”

The company aims to build on the success of its big
Flying Tables with the introduction of a new system called Aluma Dek.

“We expect to launch this lightweight aluminium panel and beam quick-strike decking system by the end of the first quarter of 2006. Like all of our products, it will be manufactured in the UAE and will be suitable for virtually any sort of in situ concrete slab construction — from multi-storey towers to villa complexes.”

What sets this new product apart from the competition, according to O’Riordan, is speed. “You’ll be able to cast concrete decks and then remove the decking material and transfer it to its next position very quickly. Ultimately it depends on what the consultant will allow you to do, but for the spans we’re looking at, you’ll be able to take the deck out within 72 hours and move it to its next position, leaving the shoring behind.”

To help keep pace with Aluma’s growth and new product
launches, the company is about to move into a new purpose-built site in Al Quoz incorporating two-storey offices, fabrication facilities and a 9000 m2 stockyard, that can be expanded upon if required.

One of the biggest formwork projects in town (or anywhere else, for that matter) is Emaar’s Burj Dubai. Now standing at around the 20-floor mark, the project is presenting some demanding formwork challenges.

Austrian firm Doka is supplying the self-climbing formwork for the tower, which is expected to reach a height of around 800 m when completed.

Following the pouring of the heavy foundations in autumn last year (also using Doka formwork), and the subsequent site installation work, the main formwork assignment got off the ground in March this year.

The architectural form of the tower means that the formwork for the shaft core and wing walls needs to be highly adaptable. In turn, the extremely tight construction schedule also calls for an ingenious and streamlined utilisation plan.

With its Y-shaped floor plan, the three-element tower thrusts upwards from a pyramid-like base, with setbacks occurring at each element in an upward spiralling pattern. Towards the top, the tower shaft tapers to form a finishing spire.

Often varying from one floor to the next, the building’s complicated floor plates present a key formwork-engineering challenge in the construction of the shaft core and walls of the three wings of the building.

Safety is paramount when working at such heights, and this is compounded by high wind speeds. To counter this, Doka’s automatic climbing formwork is designed to withstand extreme wind speeds of more than 200 km/h, and is completely enclosed in a steel grille to provide the greatest possible safety for the crew at these heights.

While Doka is supplying the self-climbing formwork for the Burj, Germany’s Hünnebeck is providing the plan and materials for the wall, soffit and joist formwork for the five to nine-story podium area — in addition to the soffit and joist formwork for the first 10 stories of the tower itself.

For the soffit areas in the podium and tower alone, Hünnebeck is supplying 9500 m2 of Variomax wooden beam formwork, almost 5000m2 of table forms, 900 ID 15 frame supports and around 12 000 tubular steel props to the site.

All of this will be joined for the walls and columns by approximately 1000 m2 of Manto giant frame formwork, 14 Manto column sets and almost 700 m2 of Ronda circular formwork.

According to Frank Odzewalski, CEO of Hünnebeck Middle East, the main advantage of using the Manto giant steel-frame formwork on the walls is its aligning clamp, which connects the Manto panels flush with tension- and vibration-resistant joints in a single action.

“The easier the handling of the formwork equipment employed, the smoother the operations on site,” he says.
The region’s busy formwork industry is also providing excellent opportunities for Mivan, which specialises in hand-held aluminium formwork systems.

“All of our projects to date in Dubai have been 30-storey plus residential contracts,” says Steven Murray, Mivan’s Dubai-based business development manager.

Here, the firm has just finished working on two towers at Dubai Marina: the 52-floor Al Fattan Marine Towers and the 41-floor Al Moosa Tower.

Murray says the Al Fattan towers project was particularly challenging due to the tight construction programme: “We were doing five to six days per floor, so speed — as well as
quality — was a key element on the project.”

He says it is important to work together and coordinate with all the trades on site to make sure that the formwork progresses as quickly as possible. This means good coordination on site with the main contractor and with Mivan’s supervisors.

“Meeting deadlines often means squeeze production in our own factory facilities and trying to get involved as early as possible with the client both pre-tender and during the tender process.”

Dubai is Mivan’s first step in the UAE market — the Northern Irish construction company has only been here for two years. According to Murray, the mature nature of the Dubai market presents many challenges.

“It’s a very competitive and time-related market: The construction contract time periods are very time-orientated, as are delivery periods,” he says.

“But the market is still growing and continuing to boom, and there’s plenty of exciting projects to become involved with in the foreseeable future.”

this is the newest masterplan
should give you an idea of what is being built around it


1 burj dubai
2 dubai mall
3 the old town
4 burj dubai boulevard
5 & 5a the residences (18 towers)
6 burj dubai lake park
7 south ridge (6 towers)
8 burj dubai business hub (6 low-rises)
9 burj dubai lake hotel (63 storeys 300m)
10 buej dubai metro station
11 the lofts (3 towers)
12 burj views (3 towers)
13 8 boulevard walk (38 storeys)

these are the projects announced and under construction within the complex, except the metro station

now you can also see how many plots for towers on the left side of the burj dubai are yet to be announced!!!

tower and what exactly that means.

When a foundation is specified, what are the key specs? Is it the amount of vertical pressure it can sustain before it fails? Is it the amount of shear force? Are there any structural engineers who can answer this? What does it mean to be able to support a building of a partcular height? Pressure on the foundation is mass/area. What mass does the 950m spec refer too assuming that the area is the area of the pad uniformly distributed? Couldn't
one go taller by making a skinnier building to keep the mass the same?

Wouldn't the building height then be limited by the building stabiliity itself rather than the foundation. 950m sounds rather an odd number for us to just take at face value without knowing its engineering origins. I see no reason based on the foundation alone why one couldn't slap a 350m needle on top of the building!

thoughts?

The foundation size for a slab foundation like this one is based on the bearing capacity (pressure resistance) of the soil beneath the foundation. The amount of bearing capacity of the soil determines how big a footprint can be placed on the soil. The bearing capacity is site, so one site might be able to support more than another, without having to go to caissons or piles. So there is not particular value, other than what the site can hold, so maybe this site could not support this much load without going to a different foundation system.

The thickness of the slab and the amount/size of rebar in the slab is designed to resists punching shear. The shear is based on the loads present in the building, so depending on the design, they might just size the slab for the highest load, or most likely they will thicken it, add more rebar in areas where columns are coming down throught the building (especially around the core area).

You will also get huge moments built up at the base of the tower from the amount of wind pressure and earthquake forces that will have to be designed for. The foudnation design will also have to resist the tendancy to slide or overrotate based on these forces.

Any other questions, I might be able to help. I do some tower design here in the U.S., and have some limited experiance (but obviously with nothing near this magnitude, the tallest I have worked with is 35 ST.)

everything is under construction except 10 & 6
not sure what's up with 13, there is no way we can see what's going on in this area
4 is the burj dubai boulevard, they have built a road which will be a part of it
they will demolish it again though, it's not wide enough, just to ease construction traffic for the future

ETA joint venture in $272.3m Burj Dubai deal
Posted: Monday, January 09, 2006
Dubai

An ETA-led joint venture with Voltas and Hitachi has won a Dh1 billion (around $272.3 million) contract for mechanical, electrical, plumbing and fire-fighting works for the world’s tallest tower – Emaar’s Burj Dubai.

The challenges ahead of the joint venture will be to meet the highest quality standards required for such skyscrapers and to meet the scheduled completion date of December 2008.

ETA is executing this prestigious project with joint venture partners - Hitachi Plant Engineering and Construction Company Ltd Japan and Voltas Limited of India.

The Burj Dubai is the ‘jewel’ of the entire 500 acre Burj Dubai Development and will feature one of the world’s first Armani hotels, luxury residential apartments, boutique offices and a host of world class restaurants and leisure options.

Currently growing at a rate of one floor per week, the Burj Dubai is located off Shaikh Zayed Road at the heart of the mixed use development which when completed will create an elegant new downtown for Dubai.

The Burj Dubai development will also host The Dubai Mall – the largest mall in the world when completed, Burj Dubai Business Hub – commercial offices and a variety of living options varying from the traditional Arabic inspired Old Town to the ultra modern lofts.

ETA Group, an ISO 9001:2000 certified company, has also been associated with several premium projects such as Emirates Towers, Dubai International Airport, Deira City Centre, Dubai Convention Centre, Dubai Marina, the Gardens Jumeirah Island and Springs Villas among other landmark projects in the UAE and other Gulf Countries.

Emirates Trading Agency-Associated Constructions and Investments (ETA Ascon) is a multinational and diversified Group established in 1973 as a joint venture under the UAE’s Abdulla Al Ghurair Group and Amana Investments,

Emaar Properties, the Dubai-based Public Joint Stock Company, is listed on the Dubai Financial Market and is part of the Dow Jones Arab Titans Index.

Very good.
I guess it's time to start watching thier website now for promotional pics.



SSP still showing level 13 pics. I guess there really is no comparison between the two websites as far as quicker to post updates.

burj dubai complex is 1km x 1km.

'the most prestigious square kilometre on the planet' as they call it.
