hello everyone this is teammate consisting of Kim hye-won Lee Nam hoon Cho a rah and Justin Chan today we will be presenting about the Haida alum center in Baku Azerbaijan the presentation will cover a brief history and purpose of the Heydar Aliev center as well as construction design and communication issues of the building process starting with a brief history of the building the Haida our leave center was proposed as the main cultural center that would represent the future direction of the country of Azerbaijan it aimed for design that broke the traditional Soviet landscape of the country it served as not only a representation of Azerbaijan independence but also as a movement of optimism for the country's future arts and culture the center was constructed to serve as an auditorium Museum Plaza and cultural meeting place with public areas restaurants and parking facilities for the city and its people large cultural events are often held at the Haida our leave center as well as many different city and museum exhibitions in addition the centre was also used as a part of Azerbaijan's bid for the 2016 Olympics the building's exterior is meant to mimic topography being a single continuous fluid surface that splits and curves around the entire exterior the beginning of the exterior acts as the ground surface of the plaza and Rises into the formation of the building from there undulations bifurcations and folds split the singular building into different sections forming the museum concert hall and exhibition halls the elaborate formations welcomed visitors by guiding them towards the building as part of the landscape of the surrounding area for some background in statistics on the building the employer is the state property committee of Azerbaijan located in Baku Azerbaijan construction of the building started in 2007 and ended in 2012 the area of the building is about 57,000 and 500 meter squared with the cost estimating to be around 250 million dollars USD the architect in charge of the building was AHA Hadid and her architecture firm Hadid Architects with the main cottage contractor being dia with additional contractors of a KT Tunstall engineers and the RO and many more next we move into the design issues of the Heydar Aliev center beginning with the design concept the main design concept the center is fluidity the building blurs the conventional difference between an architectural object in urban landscape as the building envelopes around the area as an urban Plaza interior and exterior of the building you may ask how can this complex freeform envelope be designed let's take a look at practical aspect to determine the modeling of the space structure for the freeform envelope enclosing this building the general requirement for the structural system supporting the envelopes was to provide a construction system in which the cladding panels could materialize the skins during the design not only the visual appearance but also the functional aspects are considered to materialize the structure am er o tsk spherical notes space frame system was chosen the task of the structural geometry designer here is to use the possibilities and advantages of the chosen construction system as well as limitations to design a spatial structural network which satisfies as many requirements as possible in the best way the space frame geometry proposed for the baka cultural centre is commonly used square on offset square double layered grid as shown in this picture this picture indicates the initial line length and orientation optimization would in the framework of the general design parameters a line length optimisation coupled with the line orientation strategy has involved whenever the possible to achieve a highly homogeneous and continuous configuration there are three aspects modifying the initial geometric optimization first the support positions and interaction with internal architectural elements second the variable distance between interior and exterior skins and lastly the apron at the Museum in the dovetails to the library auditorium the pictures above show in plan view the resulting internal and external grids for the both space structures where the oxide layer shift between both grids can be appreciated the pictures below are the examples of the interaction of double layered structural grid with interior architectural elements in this slide these pictures show the variable inner skin distance and think those space structure of the library auditorium and Museum respectively here are the apron and dovetail structures considered they depict complex transition from the double-layer space frame to the one-leg construction of the curved steel sections like at the pictures lastly here is the complete space frame model with all the considerations I mentioned before the final 3d line model of the space structures for the BOK cultural center serve as the basis of the subsequent structural analysis and CAD processing of the construction and for the generation of geometric information for the fabrication of the space reference components also the model constituted geometric constructional basis for the further engineering and construction of the enclosing cladding surfaces next I'll be discussing about construction issues of the building for some background on the framework the Haida Eileen Center principally consists of two clearing systems one the concrete structure into the space frame system in order to achieve large-scale column-free spaces that allow the visitor to experience the fluidity of the interior vertical structure elements are absorbed by the envelope and curtain wall system the space frame system enabled the construction of a free-form structure and save significant time throughout the construction process while the sub structure was developed to incorporate a flexible relationship between the rigid grid of the space frame in the freeform exterior cladding seams the external solid scheme is the most important architectural feature of the building it has a 3d freeform geometry and is both of several layers of different functions efforts were made to facilitate design production logistics of the solid skin and to achieve the unique appearance proposed by the architects let's take a look at the function and the substructure of panels used in this building the first layer is a prefabricated weatherproofing tray system which rests on top of the chord nodes of the main roof structure space frame and best exhibits a faceted geometry the trays consists of 2-u session purlins a trapezoidal metal deck in-between a self-adhesive vapor barrier a layer of rigid non flammable rock wall insulation boards and a weatherproofing membrane on top in a special overlapping system covering the gaps between the two adjacent trays this picture shows a substructure in one panel the white solid skin is an open joint rainscreen cladding system which required a secondary substructure to fix it in the space frame the secondary steel structure is attached to the nodes of the space frame by means and rods from there the secondary steel layer is responsible for interfacing between the faceted nodal regular space frame cord nodes geometry and the solid skin joint pattern defined by the architecture now let's take a let's talk about the exterior skin of the panel introduced earlier the exterior skin is divided into the solid skin of the building and the plaza with a steady and invisible transition in between the total surface is about thirty-nine thousand one hundred meter squared for the solid skin it and another nine thousand meter squared for the plaza there are two main materials used to make the panel's GF RC glass fiber reinforced concrete and GF RP the last fiber reinforced polyester the G RFC is to use on surfaces that are walked upon in the positive spaces and the GF RP is used as the roof cladding panels which are lighter in weight and have a more compatible color and surface finish the interior skin of the building has the same geometric complexity as the exterior skin for the technical system extensive research into their various options was needed to create these unique interiors two basic methods were investigated a panel mold-making approach as used for the exterior skin and a cold benching approach lastly when constructing the hata I'll leave Center there were a lot of issue that resulted from miscommunication to recap the complexity of the building there are about 15,000 panels each with an individually curved geometry in sizes of up to maximum of 1.5 meters wide and 7 metres long not equal to each other in addition there are 40,000 metres of 3d computer-generated substructure metal tubes underneath the panel's each unique and perfectly matching the panels at their fixed positions as mentioned each panel had a different curved geometry those making traditional manufacturing the panel is extremely difficult to solve this an adaptable mold that can change shapes was used so instead of making a different mold for each panel they made a transformable mold that could be shaped into a specific panel and check for depth ability since Azerbaijan was also a remote country that had even very basic tools must be imported the constructor had to generate all the production information associated with the exterior panels to be out sourced so that they can be manufactured then shipped to the site for installation by local workers the panels are screwed to fittings on the space frame once constructed microchips are fitted to all the 16,000 panels so these could be traced dramatically accelerating the instant installation time of the panels this video here shows the panel construction process and interviews of engineers before I show you the video how to do some of the scenes here for ironworkers are sitting on the piece of tube steel of the space frame the width of the balance beam is just four inches in this scene shows that each panel is lifted by a crane then fitted into position by hand they have to position each panel with just a half-inch of tolerance lastly in this part the crew has to line up the bracket on each of the corner of four bolts of the space frame plate finally here's a 30 second video and any presentation thank you shake that had to be really challenging engineering feat yeah we have a concrete core and we have a steel space frame which allows us to do this freeform these panels have they been custom-made we able to solve this by making a mold which actually can add up so instead of doing different molds for every panel it's like we make a mold which transforms an adaptor check that every final is different it's all complex geometry some of them are flat some of them are single curvature some other where double curvature this is amazing we're riding all the way up to the top of the vulture Center right now you
