Atrium 2

Project description: • Commercial Development project; 14 storey office building • In the heart of Warsaw central business district • Gross leasable office area of 20 244 m2 • Retail area 200 m2 • Technical solutions for reducing use of water and primary energy

Value Engineering: Originally the façade was designed as a column-partition façade with fibre concrete 3D elements. Skanska Curtain Walling and Façades assisted Skanska Property Poland to redesign the project in order to minimize risks during installation and to cut costs. The final solution comprises of unitized curtain walling elements – increasing safety on site – and 3D elements made of metal alloy sheets – helping to reduce costs and fulfil fire requirements. Together with aluminium supplier Skanska Curtain Walling and Façades was developing five different matrixes for new aluminium profiles including the sealing and insulating accessories. All profiles were approved by testing for its water resistance, air permeability, bearing capacity and bending.

Execution: Installation of curtain walls is running simultaneously with ongoing construction works in top floors – installed elements are protected with foil. Due to the limited space on site Skanska Curtain Walling and Façades rented extra space in Warsaw for material storage near the site. Material from the storage space is delivered by smaller vehicle according to the logistics and site time schedule. For smoothening processes our team on site is enriched by our Polish colleague who is aware of the local standards. This makes communication on site easier. The execution of Atrium II is made in consortium between Skanska Poland, Czech Republic and Slovakia, utilizing all possible Skanska in-house resources.

City Green Court

Project description: • Commercial Development project, 8 storey office building• Located in the heart of busy commercial and retail district• Gross leasable area 16 300 m2

• Combination of modern features of the famous architectural studio of Richard Meier designed to meet LEED Platinum

• Distinctive vertical solid panels with fins angled according to the sun´s orientation to minimise solar heat gains

Value Engineering: Skanska Curtain Walling and Façades were involved in the project very early with the cooperation starting in 2010 when our Engineers visited the architect’s office in New York together with the Commercial Development team. Designing the curtain wall required finding a solution for anchoring exterior fins for sun shading in combination with keeping very strict thermal properties (0,84 W/m2K) and finding optimal ratio between glazed and opaque areas.High acoustic requirements (47 dB) for interior glass partitions lead Skanska Curtain Walling and Façades to develop new double walled system for interior walls in cooperation with Schüco, Germany.

Execution:Installation of 6 500 sqm was completed with 8 assemblers on site in 6 weeks. The skylight covering the atrium was installed using a specially designed platform on the top floors in order to avoid using scaffolding and therefore allowing the space for all other interior works.

Corso Court

Project description: • Commercial Development project, 7 storey office building • City Centre location in the heart of an evolving business district• Gross leasable area 17 000 m2

• Designed by the world-class architect Ricardo Bofill, offering its tenants modern, unique and efficient office space designed to meet LEED Platinum

• Sustainable energy-saving solutions for minimizing the building’s environmental footprint and significantly reducing its operating costs

• Project fully designed in BIM, using BIM coordinator

Value Engineering: Being involved early, Skanska Curtain Walling and Façades participated in many design meetings with Ricardo Bofill, his architects and Commercial Development team helping to find optimal solution for the façade. This included selection of material and the way of installation resulting in less time spent on site. The main task from an architectural point of view was regarding the 3D composite cladding installed on the curtain wall, its alignment and connection detail with remarkable ‘Red element’.

Execution:The Installation on site began before finishing the concreting works in the upper floors. This required using a mobile crane in combination with the site crane, based on its availability. Installation of 6 500 m2 curtain walling was completed in two months with 8 workers on site. During production the curtain walls were equipped with built-in sun blinds which after installation were connected to the central control system.

Czech Technical University

Project description: • The Building of Architecture was erected in 1970 as a part of University Campus• Inner working climate is challenged by East-West orientation of the building• The University invested in the refurbishment under specific requirements including creating

a better working environment for staff and students and maintaining the external appearance of the building

Value Engineering: Preparations before starting the refurbishment comprised of the analysis of material in already installed modular façade with regard to its dismounting. The results of this analysis drew special attention to the materials used for fire closures in between floors – asbestos. All further procedures were planned with regard to this hazardous material.For keeping the original look of the building, façade system Trigon Unite L by Hueck Hartmann was used in this project.

Execution: The dismounting and removal of the original façade was carried out by our specialized in-house team and in conjunction with Skanska Azbest, Prague (Asbestos disposal company). The Installation was performed during full operation of the University; therefore special measurements had to be taken to ensure safety on site. The new façade was produced with in-built motorized sun blinds to create required working space inside the building.A record installation time was achieved on Eastern façade (2 700 m2) where dismounting of original façade and installation of new one took half of the originally planned time, only 17 days.

Project description:• Penta Investment project, 7 storey office building with retail space in the ground floor• First project of the extensive development of Waltrovka brownfield, designed to LEED Gold• Gross leasable area of 27 000 m2

• A-class standard office space

Value Engineering: Through optimization of number of elements (creating the round shape with elements wider than originally planned) we could lower the carbon footprint through reduced consumption of aluminium profiles, accessories, transports and shorten the time of installation. Additionally through accoustic analysis Skanska Curtain Walling and Façades were able to reduce the amount of acoustic walls on the roof (installed only where neccessary) and therefore helped to lower the final costs while keeping the required parameters.

Execution: Execution was managed in shorter time than expected – whole 13 600 m2 of façades ware completed in 9 months. In order to speed up the execution according to the Client’s requirement all architectural details on elements were installed additionally from platforms after closing the building against weather conditions.

The installation lasted for 9 months and was completed with an average of 20 workers on site.

Biomedicum

Project description:• Karolinska Institutet research space investment on Solna Campus• Ultramodern, purpose-built facility for experimental medical research• Premises space of 55,000 m2 will accomodate approximately 1,700 researchers • Effective use of shared infrastructure within Kolinska Campus• Biomedicum will become one of Europe‘s largest research laboratory.

Value Engineering: Special design of double skin curtain wall with exterior skin creating the „saw-tooth“ effect required over three months of design optimization. A Total number of 13 customized matrixes was designed in order to satisfy Investor’s requirements and ensure the technical properties of the façade. Purpose of the building – laboratories – required the design to meet specific fire requirement for the curtain wall. Therefore each floor void is designed to ventilate separately in order to avoid fire spreading.

Execution: To minimize carbon footprint and reduce the number of trucks, it was decided that the transport of double skin façade will be done separately for interior and exterior skin. The final element will be completed on the floor in-situ. In order to minimize risks during assembly, the cooperation with local recommended façade company (FasadGlas) was established.

Green Court Bucharest, buildings A, B and C

Project description:• Commercial Development project, three 11 storey office buildings• Located in one of the most dynamic parts of the city• The complete project consists of three buildings (A, B and C) totalling in gross leasable area of 52,000 m2

• The first phase of the project, building A with 19 500 m2 of leasable area was delivered in the last quarter of 2014

• The second project, building B with about 18 000 m2 of leasable area will be delivered in the summer 2015• The third and last phase, Building C, is currently under construction

Value Engineering:The design for curtain wall was challenged mainly by local conditions in Bucharest, typical for its regular earthquakes. Standard connections between façade elements were re-designed and tested to allow horizontal motions while at the same time keeping the technical properties of curtain wall. Similar challenges were also considered in the design of spider glass façade in the ground floor, especially in design of its steel sub-construction.

Execution: Execution on building A was challenged after completion by the client’s decision to change the colour of the façade from green to orange. In order to avoid waste of green glass the replacement was treated carefully and the glass was reused on building B. The challenge after completion of building B was to additionally replace 18 fixed glazed units with standard windows. Completion of 18 000 m2 lasted 16 months with average of 15 people on site.

Kapelanka 42

Project description:• Commercial Development project, two 9 storey office buildings• Gross leasable area of 60 000 m2 of a modern class A office space• Designed and built in accordance with the policy of green, sustainable building process• With goal for the construction to use as many local products as possible, therefore the whole Skanska

Curtain Walling and Façades execution was modified in order to help Skanska CDE to achieve the goal

Value Engineering: The curtain walling in Kapelanka was designed as a column-partition façade installed on site from scaffolding. The requirement for design was a special chameleon effect changing colour in accordance with the angle of sun light (special composite boards). For reaching the required comfort internally the façade was designed to allow the day light in a minimum of 75% of working space. The façade also meets the requirement for low-emission materials used in construction, which contain minimum VOCs and substances harmful to health.

Execution: Execution was divided into production of aluminium profiles in Skanska Curtain Walling and Façades, production of composite cassettes with contracted manufacturer and glass deliveries right on site. Installation was executed from scaffolding with continuous construction works in upper levels. Installation of 14 000 m2 was finished in 11 months, with an average number of 30 labours on site.

Malmö Kontor

Project description:• Skanska Öresund AB investment project; 8 storey office building• Gross leasable area of 10 000 m2

• Dynamic and architecturally interesting building with varying heights • Designed by the internationally renowned and award-winning architect Dorte Mandrup• Malmö Kontor is situated close to project Malmö Live, complementing the leisure set up with

a commercial offering

Value Engineering: The design is inspired by glimmering seas and solar shading fields so that exterior impression achieves the game between sun, light and shadows while contributing to indoor climate through solar shading effect. Technical solution for such curtain walling elements required months of calculations and testing of the resistance of anchoring points for decorative elements. New technology for glass reflecting as much heat and transmitting as much light as possible through large screens on building was used to ensure the interior comfort.

Execution: The elements were fully completed in Skanska Curtain Walling and Façades production hall so there was no necessity for extra works on site. Such system sped up the construction process and enabled finishing the building two weeks earlier.The installation lasted for 4 months of installation with average number of 15 workers on site.

Malmö Live

Project description:• Private Public Investment of the City of Malmö, Hotel Clarion and Malmö Symphony Orchestra

consists of 25 storey hotel, concert hall, congress hall and a restaurant• Built in the heart of the city• The hotel section consists of 445 rooms, spa and two large restaurants, one of which is a sky bar on

the 25th floor • The large, flexible conference building offers a wealth of innovative exhibition opportunities• The concert hall boasts worldclass acoustics• The whole complex will open in the summer of 2015

Value Engineering: The original façade design for this project considered using ceramic tiles on a wooden frame which would be completed on site. Being involved early, Skanska Curtain Walling and Façades designed a customized curtain walling elements with an aluminium support structure for the ceramic tiles preassembled in our production facility. This enabled a cost-effective alternative and provided reliable structural performance. Using this solution we were able to reduce assembly time, costs for both sides and improve logistics.

Execution: Fast and effective assembly of curtain walling elements sped up the delivery by two weeks than originally planned. 18 000 sqm of element façades were installed in 6 months with average of 20 workers. In order to reduce the carbon footprint through reducing the number of trucks, specially designed “foldable” cages for transportation of elements were used so the number of returning trucks was reduced to one-third.

Project description:• Statoil SA investment project in a new headquarters • 5 office buildings connected together through a steel-glass atrium• 6th building standing alone from the office complex is facilitating the main entrance and canteen area• Gross leasable area of 55,000 m2 accomodating 1,100 employees• Project implementation in accordance with Skanska‘s Green Workplace concept

Engineering: Challenges in the design were to combine the advantages of modular façade with using new architectonic solutions and materials. The key for success was finding suitable materials and the right sub-contractors from around Europe. For final execution fiber-concrete boards from Denmark and aspen wooden slats from Latvia were chosen.

Execution: The whole execution in Bergen was completed with our own in-house labour and lasted for two years. Skanska Curtain Walling and Façades were highly commended as a good example in health and safety on site by both Skanska Norge and Statoil SA. The successful completion was challenged by Norwegian weather – therefore the right procedures for installation had to take in account difficult conditions on site.

Green Towers, Wroclaw

Project description:• Skanska Commercial Development project; two 10 storey office buildings• Gross leasable area of 23,300 m2

• Conveniently located in the proximity of Wroclaw’s Old Town• Green Towers was the second office investment by Skanska CDE in Wroclaw• Designed in accordance with LEED Platinum requirements

Value Engineering: The original design considered standard column-partition façade, however early involvement of Skanska Curtain Walling and Façades allowed changes to the design and the whole concept was modified into curtain walling elements. This benefited the project as it shortened the time for installation, reduced risks on site through lowering the number of workers and eliminated usage of scaffolding.

Execution: Green Towers in Wroclaw was Skanska Curtain Walling and Façades’s first project in curtain walling systems outside the Czech Republic. Therefore a new way for transportation of the elements had to be designed in order to increase its effectiveness over long distances. Special cages were made accommodating 7 elements per cage with 3 cages taken on one truck (equalling 21 elements per truck) reduced the number of vehicles to one half and lowered our carbon foot print in this project. The façade works on site lasted 11 months with average number of 10 workers.
