In all times of history, engineers and architects have searched for opportunities to develop adaptive structures, buildings and building parts, which are equipped for adjusting to ever-changing requirements and conditions. The reasons behind this interest relate to the growing need for functional/ spatial flexibility, sustainability and extended capabilities of structural performance. Recent advancements in construction technology, robotics, architectural computing and material science have increased the interest for these structures/ systems; and allowed us to develop examples that are more advanced. This paper aims to introduce the state of art contemporary adaptive systems in architecture and structural engineering; and presents a future perspective for these systems and their potential applications in the construction industry.

It is thought that climate change will radically affect societies in the future, leading to radical changes in the structural and spatial mechanisms of cities. Today, most of the World, particularly 10% of the World's population living in settlements below the sea level are expected to be affected by extreme climatic conditions such as sea-level rise, change in ocean currents, destructive weather events and heat waves (IPCC, 2019). As discussed in the literature (see. Hjerpe & Linner, 2009; Foust, 2009), in this study, the most severe effects of climate change are described as a dystopian period. In this direction, the study aims to share and discuss the samples of futurist urban utopia thoughts for the environments such as floating, underwater/sub aqua, underground/subterranean and overhead/aerial (sky, space), which are considered as uninhabitable or difficult to live under normal conditions together with their structural and spatial properties, in order for societies to survive in the dystopia of climate change. In the context of climate change, the futurist urban utopias, which are envisaged for different environments, are analyzed through four variables; technological features, ways of obtaining resources, spatial and urban form conceptions, and their mutual evaluation has been determined as the method to be followed in the study.

The most controversial aspect in heritage conservation; is determining the values of monuments. Each value has attributes that can be shaped and consequently impact the society’s mindset and approach towards their heritage. The whole process starts with historians and conservators who can contextualize the monument and set up their conservation plans. However, this process doesn’t guarantee the recognition of real heritage values by the societies. Therefore, the after-plan phase is crucial in evaluating the conservation project’s effectiveness in various aspects. This paper questions the discipline of heritage recognition and the conservation project’s evaluation in Egypt where many conservation actions neglect their true values and alter the originality of monuments. Moreover, investigates the role of the Conservation project’s “Monitoring” as a new actor in re-establishing values to be pursued by the society through site visits to successful conservation projects in Cairo and analytical surveys regarding their performance and the social responses.

The fact that humanity realized the damage it caused to the environment and expressed the situation in scientific meetings has led to the emphasis on the importance of sustainability and to determine the measures and targets to be taken. Considering the future, the measures to be taken and the systems to be implemented in the environment we live in to prevent environmental problems have great importance. The success of sustainability activities on a global scale is possible with the integration of sustainability studies at different scales by harmonizing with each other. The sustainability that will be provided at the residential settlement / neighborhood scale will greatly help to achieve success in urban areas too. The study will focus on examples of sustainable new settlements located outside the city, on the periphery of the city or within the city, as well as existing sustainable settlements that have been transformed and improved in the city. An evaluation will be made on the basis of which principles these settlements have been designed and implemented. In sustainable settlements, the role of the architect in the context of social dynamics will be questioned and inferences about where the architect is located in sustainable settlement design will be evaluated.

The commercial dynamics that the city of Annaba has experienced in recent decades, due to social and economic development and market liberalization, have changed its urban and architectural heritage. This city, located in north-eastern Algeria and created before the tenth century, has seen many civilizations and dynasties pass by. Every civilization has left behind traces that time has sometimes taken care of protecting them, to bequeath us or erasing them completely. This heritage wealth testifying and telling the story of our ancestors' past, unfortunately, began to lose its value and originality after the transformations and modifications that took place in the old residential buildings inherited from two opposing cultures by integrating new forms of commercial activities. The objective of this communication is to analyse and measure the evolution of these mutations, with a focus on the ancient colonial areas of the city of Annaba where the phenomenon is most pronounced.

As a result of the constantly increasing needs, developments in technology and industry cause an increase in waste. With the increase of wastes, it has become necessary to recycle wastes in order to reduce the environmental problems that arise. For this purpose, many sectors try to minimize the expenses during the manufacturing stages, energy consumption, raw material, and space usage as much as possible. In the construction industry, where raw material consumption is the highest, the most consumed raw material is aggregate. Approximately 95% of the materials used in road constructions consist of aggregate, and the aggregate used is obtained from the quarries. The need for aggregate quarries is increasing day by day and the general structure of the earth is partially deformed. In this context, the wastes generated in the marble quarries of Bilecik province were evaluated as road base material according to the Turkey Highways Technical Specification (TKTŞ). Laboratory experiments defined in TKTŞ were carried out and the results showed that marble wastes can be used as road base material. As a result, using marble wastes as road base material will provide an environmental and economic benefit.

Architectural design curriculum is based on the premise that students want to learn Architecture. However, there is a significant decline in the motivation and enthusiasm of Architecture students for designing projects within the studio courses. This phenomenon can be the natural result of the Covid-19 pandemic that locked young architect candidates down, forcing them to attend courses online. However, the motivation behind the act of designing is loosely related with the designers’ physical or online presence. This study aims to understand the basic motives underlying the desire to design by examining online architectural design education processes. The paper looks into cognitive processes, neuroscientific knowledge around the act of design, and pedagogical knowledge around learning to design. The main question of the research is to see whether the motivation to design can be explained

Unit Price Method (UPM) and Unit Area Cost Method (UACM) are widely used in the cost of reinforced concrete multi-storey housing buildings. In this study, it is aimed to determine the cost estimation method with high performance (its use will provide an advantage to the estimator over the other) by comparing the cost estimates in the modeling by making “Regression Analysis” (RA), with the data of such struction. In the literature review, studies of equivalent and different structures were evaluated. In modeling; Number of rooms, floor area, total area, number of floors, floor height, facade area, facade void area, Bathroom/wc areas, balcony areas, building height are parameters. UPM and UACM based costs which were created with the data of 2020 of 41 similar structures (38 for modelling, 3 for tests) were used as independent variables, and cost models were created with linear regression analysis. The results were randomly selected and compared with test groups that were not used in these models, and the error rates and performances of the methods were tested. According to the comparison, in the UACM analysis, there was a high R2 value in 6 data and a low error rate in 8 predictions; In the UPM analysis, it was determined that an equally high R2 value and a low error rate occured in 7 predictions. As a result, UACM reached a better performance in finding the estimated cost; It has been observed that using it in cost estimation gives better results. However, even if UACM performed better, the difference in error rates is very low, at 2.7%.
