Successful construction with PERI

SKYDECK – the light-weight slab formworkfor large-scale projects on fast-trackConference Center on Parcel A01, Riyadh, Saudi Arabia

Daniel Keogh, Senior Construction Manager: “The project involves multiple work fronts that require multiple solu-tions. The PERI range of systems, especially for formwork, enabled the construction team to address each differing situation with a system to suit. Where individual work areas incurred varying conditions, the flexibility of the PERI systems al-lowed for adaption of the formwork to the requirements. Each PERI system offers its own efficiency, whether through plant, resources or rotation of material, which can be imparted into the programming of works.”

The conference center is part of the King Abdullah Financial District (KAFD) in North Riyadh, which is one of the most prestigious developments in Saudi Arabia. The construction of the confer-ence center commenced in August 2011 and is expected for finalization mid

high speed erection with minimum cycle timings as well as optimizing the cost of material by using economical systems. All of the above objectives have been met by PERI. For the large number of columns the LICO column formwork was selected. Due to the easy handling and few components needed, a one day cycle was achieved with 11 sets of shutters. The contractor was able to cast the core walls in a 3 to 4 days cycle by using the VARIO GT 24 wall formwork. One major concern was the huge slab area, which needed to be casted in a very short time. PERI provided the light-weight slab form-work SKYDECK with its dropheads, MULTIPROP MP 480 and MP 350. The 24,400 m² of easy-to-use decking system and the 36,000 m² propping were utilized in a most efficient way. Furthermore, SB-2 Brace Frames have been used for the single-sided retaining walls with heights up to 4.80 m. All in all, PERI is able to provide the perfect formwork solution for any fast-track project requirement.

The large-scale footprint and fast-track program of the project required the delivery of a huge form-work volume in a short time, which was success-fully executed by PERI in Saudi Arabia, Germany and several other subsidaries worldwide.

The SKYDECK slab formwork allows a systematic and fast erection by using its few components.

The Horizontal Ledger (UH) with gravity lock: secure connection also under vibrations.

The metal decking design combines high permissible loads (up to 10 kN/m²) with low weight and a slip resistant surface.

PERI UP Rosett Flex scaffold can be used for various applications such as access stairs, access scaffold, façade scaffold, industrial scaffold and shoring. Its standard grid of 250 mm was devel-oped to ensure maximum flexibility in any direction and has proven to be highly adaptable to any structure or height.

PERI UP Rosett Flex main components are vertical standards (UV), horizontal ledgers (UH), braces (UB) and decks (UD). The horizontal ledgers are fixed to the vertical standards through PERI UP Rosett Flex gravity lock. Once a ledger is hinged into the rosett node it is immediately secured and can’t come off. The gravity lock uses vibrations on the scaffold to further tighten the connection.

All metal decks are perforated and self- locking, ensuring a high slip resistance and always safe connection to horizon- tal ledgers. All decks are hot dip galva-nized. Oil, chemicals or salt water can therefore easily be removed. Metal decks are available in widths of 250 mm and lengths from 500 mm to 3,000 mm. Any decking surface can be closed completely by using available system components. The result is a gap free and safe working area.

Economical formwork solutionsfor a project leading towards an eco-friendly future

TRIO panel formwork – the best solutionfor any project requirement

Masdar Institute of Science and Technology, MIST 1B, Abu Dhabi, United Arab Emirates

Nilona Tower, Dubai, United Arab Emirates

The expansion of Masdar Institute of Science and Technology covers the construction of a student accom-modation, seven open laboratories, a multi-use hall facility, swimming pool and a gym. It will incorporate similar energy efficient design elements such as shaded streets, natural ventilation and heat reflecting facades that makes the facility and architecture unique. The total built up area is 82,000 m² and is expected to be completed over the course of 18-months, with approxi-mately 35% size increase to the current campus.

PERI has been awarded the contract to supply formwork for columns, core walls and slabs. In order to be able to realize such project, PERI has de-signed customized solutions to satisfy the needs of the client. To achieve

Nilona Tower is located in Dubai Healthcare City Phase II, and will house 24 storeys, ground floor and 3 base-ment floors for parking. The tower will feature 352 elegant and luxurious guest rooms, 128 luxury serviced apartments, comprehensive health and fitness facilities. Guests and residents will also have an array of nutritious gourmet din-ing and be surrounded by spectacular sceneries.

The differently dimensioned reinforced concrete columns were formed with TRIO, CB 240, MULTIFLEX and PD 8 shoring support, according to the re-quirements using the optimal system in each case. By using the CB 240, the floor cycle can easily be achieved, while

PD 8 Shoring Towers provided optimal support for the typical slabs.

The Masdar Institute was established in coopera-tion with Massachusetts Institute of Technology (MIT); it focuses on research, technological development and human capital development in renewable energy and clean technologies.

With a customized solution for cantilever, PD 8 shoring, with a legload capacity of up to 70 kN, has been the ideal product choice.

With PERI‘s table modules and props the amount of single components could be reduced drastically.

The high flexural stiffness of VARIO‘s girders and matching steel walers can often be used to speed up shuttering, by optimizing the formwork panels and minimizing the number of tie points. In many cases the VARIO system yields the most cost-effective solution. The components of the VARIO system were used to provide individual, movable beam side shutters which fulfilled the requirement of preassembling and reusing of all beam shutters.

“Due to the flexibility of PERI‘s TRIO panel formwork, it was possible to cover the large variety of different vertical elements in our project. With their MULTIFLEX system, we tackled the challenges of non-typical struc-tures, covering immense construc-tion areas. For our typical slabs we used PERI‘s table forms, which allowed us to reach a short construc-tion cycle. Throughout the project we were satisfied with PERI‘s sup-port and their technical experience and solutions.“

Wolfgang Kopf,Construction Manager Formwork:

Kahtan al-Tikriti and Safwan S Boumorra,Construction Managers:“Despite the fast track nature of MIST-1B project and the continuity of the superstructure works 24/7, for a duration of 7 months, PERI proved their capability to present the site required technical sup-port and on site solutions for the complicated cases, backed up with the calculation and the praticality of the said solutions.“

keeping a safe working environment and being in need of less manpower. For forming, reinforcing and concreting the shear floors, TRIO resources were used. Swivel Head Table form served for the slab edge formwork.

The broad PERI product range and opti-mized logistical operations through only one formwork partner simplified and accelerated the construction progress. This meant, for example, that the TRIO with CB 240 wall formwork system could be used extremely versatile: for forming the core walls as well as constructing the shear walls. In addi-tion, MULTIFLEX and PD 8 slabs tables ensured that formworking was carried out very efficiently.

minimum cycle times, the client used VARIO GT 24 girder formwork system for the walls and columns. It is a fast, easy to use system that adapts to any required wall shape or height. One of the main advantages for this system is the flexibility in use, by pre-assembled panels fitting exact design require-ments.

In order to meet the slab heights up to 4.97 m, PERI offered MULTIFLEX system with GT 24 and VT 20 gird-ers and a tailor-made slab and beam support solution, with a combination of MULTIPROPs and PD 8 towers. As a result the client got an adaptable slab formwork, with individual system com-ponents consisting of props, tripods, crossheads, PD 8 towers, primary and secondary girders.

The tower is located on the most desirable and exclusive beachside Al Ras Al Akhdar district of Abu Dhabi on an area of over half a million square meters.

Mohsin Khater, Contracts Manager:“The PERI formwork system contributed greatly to the success of Etihad Towers. Not only did it provide an excellent structural solution for the com-plex project, but also provided an economical way for sav-ing manpower. I would highly recommend PERI in the future projects.“

Occupying the built-up area of the pro-ject approximately 5.1 million square metres, Etihad Tower project is a pres-tigious mixed-use development com-posed of five towers, a large multi-level podium and a four level underground parking for more than 3,000 cars.

With the use of PERI system on site, inclusive of PD 8 for supporting and concreting PT beams in the podium area, it was easy and safe to erect despite the heavy and high structure. PERI’s climbing formwork was used

for concreting corewalls from B4 to P5 in Towers 1, 2, 3. This created a cost-effective solution for the client, in comparison to the hydraulic sys-tem. Additionally, as safety on site is and has been a main concern in such heights, the unobstructed platform made the work for labor and staff safe and fast. For all typical floors in the towers UNIPORTAL table form has been used: it was customized for each tower’s shape which made it ideal for the high-rise building.

individual weights of the elements, which allow as-sembly and dismantling by hand. This means that the formwork crew is still in a position to effectively use the newly gained crane avail-ability in a productive way.
