A View to Timber Industry
2nd Speaker: Aleksei Petrushkevich, Deputy Director of the State Research and Development Institute, Russia
10.30-11.00: Restoration and Conservation of Traditional Timber Structures in Russia
Aleksei Petrushkevich presents a number of important projects on Restoration and Conservation of Timber that have already been implemented with the techniques elaborated by the State Research Institute for Restoration. Special attention is attributed to Conservation of historical Timber Buildings and Structures, as well as their constructions that are being adapted to the use in the modern context. Restorative materials that are used on the monuments located in a natural environment have to be really weather resistant.
3th Speaker: Dr.Dmitry Tuzov, Head of Department “Restoration and Timber Processing” of the College of Architecture, Design and Re-engineering N26, Russia
11.00-11.30: Educating Restorers of Timber Monuments through Real-Life Restoration Projects
Dr.Dmitry Tuzov; The Department “Restoration and Timber Processing” of the College of Architecture, Design and Re-engineering N26 has an experience of education programmes including traditional educating process, modern one, as well as individual restoration projects for students. We involve our students in real-life research and production projects. It includes items of furniture, decorative and applied art objects, as well as architectural sites.
4th. Speaker: Arnstein Brekke, Carpenter, and Engineer, Project Manager Member of National Board of ICOMOS Norway, National committee: Wood, Norway
11.30-12.00: Conservation of Timber Constructions in Norway
Arnstein Brekke; will give an overview of Norwegian building traditions in timber structures, from the oldest known from the 10th century up to the 20th century.
Buildings are built and kept, conservated and restored trough compromises. We can see different values and have different priorities in buildings. In this paper, the focus will be on the older buildings and their importance as source value. What can we learn from a building? Aspects of handcraft, technology, resource economics, variations of wood used for different purposes as climate shell and constructive measures, traditional ways of reuse of buildings or elements, cultural traditions, and aspects, regional and international influences.
There are different methods to discover and to protect this source value, and the paper will give examples on this.
12.00 -12.30: Discussion

Moderator: Prof. Dr. Deniz Mazlum
5th.Speaker: Beyza Nur Bozkurt, Architect, Mukogowa Women’s University, Japan

14.00-14.30: A Comparative Study on Traditional Farmhouses in Japan and Turkey
Focusing on Culture, Environment, and Behaviour
Beyza Nur Bozkurt’s presentation focuses to explore the relationship of environment and culture on farmhouses of Japan and Turkey through the users’ behaviors. Within the scope of the study, three farmhouses from Miyazaki, Fukui and Iwate Prefectures (from south to north) in Japan, and one farmhouse from Rize City, Eastern Blacksea Region in Turkey will be chosen.
The reason for choosing farmhouses from Miyazaki and Iwate Prefectures is they are from the southernmost and northernmost of Japan observed on-site visits so far. Thus, it is aimed to observe the similarities and differences in shaping the physical culture within Japan.
The climate of Fukui and Rize have similar characteristics. The choice of regions with similar characteristics from both cultures is also to observe similarities and differences in shaping the physical environment between cultures when the physical conditions are as close to each other as possible.

6th Speaker: Esin Eştürk, Architect, Siska A.Ş., Turkey
14.30- 15.00: Reconstruction of Sait Pascha and Kocatas Mansion on Bosphorus
Historical buildings which are Saitpaşa and Kocatas Mansions are located on the coastal road in the central neighborhood of Sarıyer. Kocatas Mansion was built in 1860-1865 in the period of Abdulhamit II by a French architect. There are records that Saitpaşa Mansion has been built in earlier periods. Founded as Elite Shores Project, the new function is located on a 30-acre land with 56 bedrooms, converted into a six-star hotel. It has a construction area of 15.000 m2. The reconstruction of the mansions started with ground works at the beginning of 2017.
15.00-15.15: Discussion
15.15.-15.40: Coffee Break

7th.Speaker: Dr. Francesca Brancaccio, Italy
15.40-16.20: Tree, Timber, and Wood: Protection, conservation and valorization of the Archeological Park of Sorrento, Italy
The study arises from the opportunity offered by the recent acquisition, by the Municipality of Sorrento, of an agricultural area of about 56,600 square meters, mainly cultivated with olive groves and vineyards, which develops for subsequent terracing to the sea, including the remains of famous Maritime Villa of Pollio Felice, known as Bagni della Regina Giovanna, dating back to the mid-1st century B.C.; inside the area there are some rural buildings and small comfortable areas to be restored and reused.
The extraordinary archaeological value of the place, together with its equally astonishing environmental and landscape importance must be protected and it is also necessary to
prefigure compatible uses in view of public enjoyment of this heritage, protecting it both from natural risks and from any speculative damages.

8th. Speaker: Assistant Professor Meltem Vatan Kaptan, Dr. Melek Elif Somer, Bahçeşehir University, Turkey
16.20-16.50: Structural Documentation: Villa Tarabya
Documentation is one of the fundamental actions for preventing and safeguarding cultural heritage. The aim of this study is to document the structural system of Villa Tarabya, the Summer Embassy Palace of Italy, constructed in 1905 - 1906 by Raimondo D’Aranco and located along the Bosporus in Istanbul. The motivation of this study is to document the structural system of this building because of its current damaged condition facing a state of disrepair. Villa Tarabya was built at the location of the former embassy building and is one of the traditional Ottoman mansion buildings which represents Art Nuevo style, constructed by timber frame standing on a masonry ground floor. Due to the sloping topography, the backyard was constructed on several terraces. Although the building was designed as the modern style of Ottoman Period it includes vernacular details of timber-framed buildings.

9th. Speaker: Süheyla Koç, Architect, Prof. Dr. Deniz Mazlum, Turkey
16.50-17.20: The Evaluation of The Repairs Executed in Beyşehir Eşrefoglu Mosque in Consideration of IIWC 2017 Principles
The wooden columned mosque tradition in Turkey which dates back to the 13th century and mostly located in Central Anatolia Region, do not get the attention it deserves, although the examples of this style have great importance for Turkish architectural history. In the context of this paper, Beysehir Esrefoglu Mosque which is regarded as the oldest and biggest wooden columned mosque in Turkey will be the case study. The mosque, which was built in the late 13th century, survived, almost intact, thanks to both the details of the construction technique and the repair works implemented during its long history. In this research, firstly, a methodology, which includes the data collection, in-situ assessment, and analyses of the structural system, deteriorations and repair history, for the examination of wooden built heritage is suggested.

Moderator: Ario Cecotti
10th.Speaker: Arch. Dl. Oliver Sterl, RLP Rüdiger Lainer + Partner, Partner and Managing Director Austria 10.00-10.45: HoHo Wien, Reach Higher with Wood: New Timber Tower in Vienna
With its 24 floors, HoHo Wien is at the moment the tallest timber tower under construction in the world. More important, however, is its future urban usage. The tower forms an integrative element in the new urban district of Aspern in the Northeast of Vienna. From 2019 there will be offices, serviced apartments, a hotel and wellness areas on 19.000 square meters usable area provided. The prerequisite for this round-the-clock usage mix is an innovative construction system: all interior walls are interchangeable so that a high degree of variability and flexibility is achieved. Moreover, these walls provide a special spatial atmosphere because the material of wood remains visible and tangible. With this flexibility, HoHo Wien shows the advantages of hybrid construction compared to pure timber construction. The cores and accessions are made of concrete, 74% of the house have a timber construction share. Developed by RLP Rüdiger Lainer + Partner this is an innovative system which contributes significantly to the combination of economy and ecology, architecture and utility value.

11th. Speaker: Prof. Dr. Civil Engineer Ario Cecotti, Boğaziçi University, Turkey
10.45-11.15: Modern Platform Construction Using CLT Plates
Since the year 2000 when first University of Graz (Austria) did research on them there has been strong and growing European interest in timber plates that are known collectively as cross-laminated timber (CLT or XLAM, shortly crosslam) as superstructure elements in low-rise and medium-rise buildings as substitutes for reinforced concrete (RC) and masonry elements. More recently interest has spread to places as diverse as North America and South Hemisphere countries like Nez Zealand, Australia, Chile, and Brazil. Such products are manufactured as large plates/panels having three or more layers of finger-jointed structural grade softwood lumber, with layer thicknesses ranging from 17 to 38 mm. There are many proprietary CLT products available in thicknesses that range from around 50 to 500 mm. Lumber pieces in some layers are arranged orthogonally to pieces in other layers, such that when layers are bonded together using rigid adhesives the composite arrangement allows the axes of these pieces “cross-reinforce” pieces in other layers. Finally, CLT is cross-reinforced in all directions in the same manner as plywood – a giant plywood, indeed.

12th. Speaker: Tom Westwood, Senior Architect, Waugh Thistleton Architects, UK
11.15-11.45: How Timber Can Save The World
Waugh Thistleton Architects have been building with engineered timber for 15 years. It’s a key attribute for the practice is it’s sustainability, however, the multiple benefits of the material enable us to use it widely – not only where sustainability is a driver. Murray Grove, a 9 storey, 29 home apartment block in London, was the first substantial building where Waugh Thistleton employed Cross-Laminated Timber (CLT), and largest building of it’s kind when it was completed 10 years ago. We have kept pushing boundaries, with Dalston Works, completed in 2017, reaching to 10 storeys, and containing 121 apartments, making it again the largest CLT building in the world at the time.

13th Speaker: Dr. Simon Aicher, Head of Department of Timber Construction
Materials Testing Institute, University of Stuttgart, Germany
11.45-12.15: Engineered Wood Products for Contemporary Timber Structures – Manufacture, Build-up, Analysis and Repair
The presentation gives a detailed overview on the most commonly used contemporary engineered solid wood-based products employed for the primary structure of timber buildings. The main focus is on glued laminated timber (GLT) and cross-laminated timber (CLT) where manufacture, build-up, engineered derivation of basic mechanical characteristics and design aspects are addressed. For GLT also the options resulting from block gluing and large finger joints are demonstrated. The po-tential of hardwoods is shown for both, GLT and CLT. In addition to the standardized products GLT and CLT, some other modern high-performance timber elements such as the so-called „Kielsteg element“ representing the world´s longest spanning box-type element are shown and discussed.
Finally the state-of-the-art in adhesive-based repair of cracked timber structures - modern and traditional - is presented.

14th. Speaker: Prof. Dr. Antonio Frattari , Dr. Arianna Cescatti Trento University, Italy
14.00-14.30: Use of the Wood in the Buildings Refurbishment: Case Study the Reclamation of a Rural Building in Trentino Region, Italy
The reuse and refurbishment of existing buildings represent, for the future, one of the most important sustainable approaches in the construction industry, considered one of the most responsible for the environmental crisis affecting our planet. The use of wood, a natural and renewable material, is a correct answer to this problem. The sawed wood helps to reduce the greenhouse effect because it incorporates forever in 1 m3 of wood 1,01 ton of CO2. The culture of using wood is not yet part of the Italian housing recovering process.
The Laboratory of Building Design at the University of Trento has developed, from the middle of 2016and the end of 2018, an exemplary case study to promote the wood culture. It consists of the reclamation of an old barn converted into an accommodating building. The adopted constructive solution introduces the use of CLT panels in order to realize an envelope inside the existing building according to the theory developed in 2002 by Prof. Antonio Frattari concerning the concept of “Envelop Within an Envelope”. To increase the environmental sustainability particular attention has been paid to the exploitation of the free energy contributions from the building surrounding and to increase the energy characterization of the envelope in order to realize a Near Zero Energy Building (NZEB) for a sustainable characterization of the building.

15th. Speaker: Nevzat Sayın, Architect, Turkey
14.30-15.00: 3 New Prototypes of Timber Use in Architecture
When timber is concerned, the first structures which flash through our minds are traditional ones. However, timber is just a construction material and it will be defined by how we use it. Since timber is almost never used in contemporary new structures in Turkey, it does not occur to us as a material in new structures. Yet, as we think of it as a construction material, we can come to realize that it can also be used in contemporary structures. From time to time, we can see timber framing as a load bearing system in structures where interior and exterior infilling and cladding are achieved with different materials. In some cases, we can see timber framing as both a load bearing and cladding system, or sometimes timber is used just as a cladding material in cases where the load-bearing system is constructed using non-wooden materials.
What I would like to stress is the use of timber in architecture practiced in Turkey today. In this respect, I would like to show forth the use of timber through three samples; namely a high-school in Ciftehavuzlar, office building in Goksu and a mosque in Malatya.
The high-school is a significant example with a precast concrete bearing system, where both the load-bearing system and the interior cladding of the top floor which incorporates a gym, a library and a student club are made of timber. The office is significant in terms of its reinforced concrete and steel bearing system, while the cladding is fully in timber, and finally, the mosque bears a significance with its massive timber structure.

Moderator: Prof. Dr. Ufuk Kocabaş

16th. Speaker: Dr. Khoi Tran, ARC-Nucléart Conservation Centre, CEA-Grenoble, Grenoble, France
15.30-16.00: Radiation Processing in France for Cultural Heritage Preservation
The Research and Conservation Centre, ARC-Nucléart, is located in the Grenoble Technology Research Centre of the French Atomic Energy Commission (CEA) and was set up jointly by the CEA, the Ministry of Culture, the Grenoble City, the Region Rhône–Alpes and the Association Pro-Nucléart. This consortium was officially created in 1989, and got an administrative status called Public Interest Group for Culture (G.I.P.C) in 1997, permitting an independent management such as a small company, offering services in the conservation-restoration of cultural heritage mainly in wood by various processes described later.
At that pioneer time, the small group of scientists and technicians took the challenge of consolidating by a radiation-curing resin the ancient parquet of the Stendhal museum at Grenoble, in 1970. The success of the operation was followed by the implementation of the
technique to the disinfection and consolidation of dry wood cultural heritage objects such as sculptures, furniture, and ethnographic artifacts. In the same time, archaeological artifacts excavated from subaquatic sites in the Grenoble area were conserved by the resin radiation-cured process, following the request and agreement of the local archaeologists and curators. In 1997, the mummy of Ramses II was successfully disinfected by gamma irradiation in the CEA Center at Saclay, near Paris. During the ’80s, the conservation of waterlogged archaeological wood was enhanced by the creation of a dedicated Center, jointly supported by the CEA, the Grenoble city and the Ministry of Culture.

17th. Speaker: Assistant Professor Dr. Namık Kılıç, Istanbul University, Turkey
16.30-17.00: Degradation of Yenikapı Shipwrecks Caused by Iron Compounds and the Solution Suggestion
Remains of 37 shipwrecks dating from the 5th to 11th centuries were uncovered during the archaeological excavations carried out under the direction of the Istanbul Archaeological Museums in Yenikapı. The wooden ship elements of the Yenikapı shipwrecks absorbed water during the time undersea and moist soil, so they became waterlogged. Waterlogged wood conservation completed with the replacement of water that was absorbed by the wood with a chemical material and the process took a very long time. Understanding of the degradation process and the cause of the degradation of the wood provides management of conservation procedure correctly. Therefore, before starting the conservation, it is necessary to know the properties of the wood before and after the degradation

18th. Speaker: Dr. A. Gökçe Kılıç, Istanbul University, Turkey
17.00-17.30: Monitoring of the Conserved YK1 Shipwreck During Storage
The maximum water content of YK 1 shipwreck, one of the Yenikapı shipwrecks whose conservation works have been undertaken by the Istanbul University Yenikapı Shipwrecks Project, was detected between 400-900 (% w/w). The maximum water content of YK 1 shipwreck woods, which is over 400, shows that the wood is heavily damaged. In order to prevent the negative effects of iron compounds on woods of YK 1 and protect the conservation chemicals, iron corrosion products were removed with mechanical and chemical cleaning methods. Due to the high degree of degradation of the waterlogged wood, it was decided that high molecular weight PEG impregnation was appropriate for the wood. When all these data were evaluated, impregnation studies of YK 1 wreck started by using PEG 2000 and continued with the use of one-stage PEG. After PEG pre-impregnation, woods were dried by vacuum freeze-drying method.
