title: Factors Affecting the Selection of Contractors in Green Building Projects

description: The growing interest in sustainable design and construction introduces new set of risks specific to green building projects. One of the challenges in green building projects that requires special consideration is the selection of the appropriate contractors to ensure that the targeted sustainability goals of the projects will be achieved. Rapid growth of green building movement requires that contractors that are willing to be active in sustainable construction learn green building rating systems, application processes, green products, and related laws and regulations. This study investigates major factors affecting the selection of contractors that will be responsible for the construction of projects aiming certification through green building certification systems. An extensive literature survey was completed to identify the significant factors in the selection process, which are important for the successful completion of the projects. It is found that experience in green building projects and certification system procedures, managerial approach, technical approach, price, past performance, and qualification are important in the selection of contractors in green buildings.

title: Public non-consultation related delays in Delivery of Mega Projects

description: Since 1994 the post-Apartheid new dispensation introduced policies that sought to effect equity in all spheres of life, Mega Projects have become indispensable as their sheer size could have an immediate impact on the intended beneficiaries. However the widespread public protestations and rolling juristic disputations have delayed most of these schemes due to costly schedule revisions. The objective of this study is to assess the delays that are directly caused by public discontentment with the projects' implementation. The two biggest Mega projects in the energy sector, Medupi power station and Kusile power stations are used as case studies to assess the delays caused by the endemic protests in the country. Interviews were held with, local communities, top government officials and professionals involved in the implementation of these projects. It was observed that most of these projects are hastily implemented with abnormally heavy pressure from the authorities in order to avoid political embarrassment. The rushed implementation leads to superficial public consultation which results in a lack of psychological contract with the local communities. Up to 30% of delays could be attributed to downtime, picketing, intimidation of workers, sabotage and general disruptions in order to demonstrate disaffection with the implementation of the projects. If consultation could be all-encompassing, meaningful and target critical stakeholders much better improved project delivery could be achieved.

title: APPLICABILITY OF WIDE-RANGE ULTRASONIC TESTING TO NON-DESTRUCTIVE INSPECTION OF GROUT CONDITION IN PRESTRESSED CONCRETE BRIDGES

description: Complete grouting of tendon ducts is important for durability of post-tensioned prestressed concrete (PC) bridges. Voids in the ducts may induce failure of PC tendons, possibly causing a reduction in load capacity and collapse of the bridge. The wide-range ultrasonic testing (WUT) is one of the non-destructive inspection techniques. The focus of this study is to examine the applicability of the WUT to grout inspection. This paper summarizes the characteristics of the non-destructive methods available for the PC grout inspection and outlines the sensing and analyzing techniques of the WUT method performed in practice in PC bridge construction. The inspection accuracy of the WUT method was examined by comparison to a sensor-based inspection method. This paper also reports comparative investigation and discusses the advantages of the WUT method including inspection accuracy, cost performance, time efficiency and safety. It was confirmed in on-site application that the WUT method was capable of determining grout condition at a concrete cover depth of 250 mm.

title: INNOVATION SCENARIOS FOR THE TECHNOLOGICAL DESIGN OF THE OPERATING SUITE: Design criteria and methods

description: Today the operating suite is considered, together with the diagnostic unit, the functional area that is more subject to profound changes, resulting in an increased technological complexity. The road paved by the new approaches to care and illness imply that the coming years will be characterized by a profound and radical change of the medical-scientific knowledge and even more so of the diagnostic and therapeutic methodologies. This paper analyses the characteristics of existing healthcare facilities, with respect to the needs created by the new role of the hospital, as well as the impacts on the more complex and rapidly changing sectors. The identification of the problems and the definition of the number of needs will allow to outline the strategies to adopt for the design of a modern operating suite, defining the basic requirements for an optimum supply of the service. The objective will be to define useful design criteria and methods to favour the inclusion process of innovative factors, so that the building unit can promptly respond to any evolution of needs, overcoming the now consolidated spatial and functional obsolescence that has characterized it lately.

title: Resilient communities for safe cities

description: The increase in the intensity and frequency of natural disasters in recent years require new methods and tools to deal with this change. New approaches must be developed to ensure the safety of cities and settled communities from these events. Implementing the resilience of a territory requires an integrated approach to act simultaneously on physical, economic and social reality. The described research had investigate on possible tools to really improve physical and social dimension. Resilience is assumed as a paradigm within the project for the construction / transformation of the built environment. Is highlighted the fundamental role of the social component in determining priorities and security issues for each specific context. Physical and social environment are characterized, therefore, as an inseparable dyad for any action aimed at strengthening the resilience and safety of the environment built. In the implementation process of the resilience of an urban system, two closely interrelated areas are identified: on one hand the community capability of implementing organizational-procedural adaptability; on the other, the physical space and the natural dimension, as a place of construction of the technological-spatial convertibility, and the ecological and environmental responsiveness. Among the several conditions to ensure adequate levels of connection and correlation with ecological factors, topological, social and technological developments of the built environment, in this paper are described those related to risk communication as fundamental first tool.

title: Experimental study of Ultra-High Performance Fiber Reinforced Concrete dosages with ultra fast setting time

description: The overall objective of the work is the development of ultra high performance fiber reinforced concrete (UHPFRC) dosages, with ultra fast setting time, that can be used for shotcrete.In this study, a number of UHPFRC mixtures with different amount of admixtures (plasticizers and accelerating) and different mixing time were tested, to increase either the rate of stiffening or setting of the concrete or the rate of hardening and early-strength development. Workability, consistency and mechanical properties of UHPFRC including compressive and flexural strengths at different ages were assessed. Results showed mixtures than begin their first setting in less than 1 minute, with very good mechanical properties in 24 hours, and without reducing the compressive strength at 28 days. From the results obtained, various uses of these mixtures are proposed taking into account, the new context of the Construction field, with the appearance of new placing concrete techniques.

title: Microstructure, Texture, and Mechanical Properties of Geopolymers Prepared using Industrial Waste

description: Alkali activation presents a prospective possibility for the reuse of waste brick powder, though it should be noted that ceramic materials were a subject of alkali activation only rarely to date, probably due to the technological difficulties accompanying the preparation process. In this case the binder can be prepared while avoiding the Portland cement entirely. Therefore, the environmental benefits are even more remarkable than if the brick powder is used as a supplementary cementing material replacing only a part of cement.In this paper, several geopolymer mixes are designed, using waste brick powder as the main component and a combination of water glass and sodium hydroxide as alkali activator. At first, the hardened mixes are subject of detailed material characterization experiments, including microstructural studies using scanning electron microscopy, textural studies by mercury intrusion porosimetry, and qualitative and quantitative X-ray diffraction analyses. Then, their functional properties are assessed by the measurement of basic physical properties and mechanical parameters. Experimental results show satisfactory performance of all analyzed mixes which makes good prerequisites for their practical application as an environmental friendly alternative to cement-based materials.

title: DISASTER IMAGINATION GAME ENHANCED BY MOBILE MAPPING SYSTEM AND ITS APPLICATION

description: DIG (Disaster Imagination Game) is carried out as an emergency drill in Japan. What is DIG ? Assuming a situation where a large disaster occurs in the region, the predicted hazard is indicated on the transparent sheet which is put on top of the regional map by using pen and seal by the participants in a workshop. Thus creating the original hazard map in the region, the information of risk can be shared in advance and the required preparation and cooperation can be recognized among the participants. Moreover, it is helpful to determine the appropriate location for the shelter and evacuation routes.However, the hazard is often overlooked since planar maps are generally used in DIG and the participants are required to predict the hazard by their prior knowledge about the region and the information acquired from the map. In this study, the new developments are proposed in which the serial video captured by MMS (Mobile Mapping System) is used as well as the map. The combination of the map and the serial video helps the detection of the hazard. Moreover, the hazard detected in the workshop is illustrated not only on the map but also in the serial video by superimposing the displays and captions. The effectiveness of the proposed system is discussed through the application to the practice of DIG.

title: CORPORATE FINAL NODAL DESTINATION CHOICES IN THE EXODUS FROM JOHANNESBURG CENTRAL BUSINESS DISTRICT

description: The opening up of the invisible barriers after the fall of apartheid in South Africa led to massive internal migrations and relocations to bigger cities. Johannesburg as the biggest economic hub not only in South Africa but in Africa pulled the majority of the new opportunity seekers from even across Africa. This uncontrolled influx led to overcrowding, increased crime and grime in the city centre of Johannesburg. The loss of value of property in this part of the city led to a lot of corporate organizations relocation to budding economic nodes in and around Johannesburg. The study seeks to understand the processes that were applied in deciding the suitable new Headquarters for these blue chip companies. The new nodes that took in the new relocators have over time assumed their own identity in terms of the type of companies that are mostly found in these areas. Although these identity nuances are not pronounced at first glance they are accentuated with greater scrutiny. The study sought to see if there is a fit between the independent observation of the characteristics of these locations and the perceived attractors to the blue chip firms. This was achieved by interviewing the executives and sending emails to some in order to understand the processes and triggers affecting their decisions. It was generally observed that prestige and locational characteristics that complemented the company's ethos were the overriding triggers in deciding on the final nodal destination.

title: THE IMPACT OF OBSOLESCENCE IN HEALTH PUBLIC PRIVATE PARTNERSHIP PROJECTS

description: Obsolescence is a major challenge in Infrastructure implementation around the world. South Africa has been implementing PPPs close to 20 years now and some of the first projects will soon come to closure as the end of their term is drawing nigh. Obsolescence is generally mitigated by stipulating that there should be a general overhaul of the facility very close to the end of term in order to preserve and elongate the economic life of the project. However the health projects are very much dependent on the ever-changing technological developments for their optimal performance. Some of the new technological equipment might require infrastructural adaptations. Through interviewing designers, managers and clients the research sought to garner information that could be helpful for future projects in this sector and that could be adapted to other sectors as well. Although it was found that obsolescence was not properly catered for, the experiences of the aforementioned respondents were valuable in proposing general considerations in future projects. It is hoped that lessons will be instructive and beneficial to the other countries which are new to the PPP procurement method, especially when it comes to the implementation of the health facilities.

title: A REVIEW OF CORPORATE SOCIAL RESPONSIBILITY PRACTICES IN DEVELOPING COUNTRIES

description: The construction industry plays a vital role in every economy by contributing substantially to the national GDP. Managing societal and environmental impacts are at the heart of corporate social responsibility (CSR). CSR has been adopted by many industries to address the negative impacts that result from their operations. Research in CSR within the construction is limited and still in its infancy, especially in The Kingdom of Saudi Arabia (KSA) where there is a negligible uptake of CSR activities and a lack of strategies and guidelines. The construction industry in KSA has not fully embraced the concept of CSR. This paper represents a comprehensive review of the reasons which often militate against the adoption of CSR in general, and specifically in construction within KSA. The paper adopts a structured approach to analyze materials published on the subject looking at CSR in general and how it has been applied in the construction sector, including KSA. The analysis indicates that there are critical factors which have hampered fulfillment of CSR requirements in construction. A lack of awareness and knowledge is the greatest barrier, and the lack of a practical and theoretical framework to examine the level of CSR implementation closely follows in tow. Suggesting that CSR within KSA is currently at a basic level and focused on philanthropic activities. Therefore,there is a need to develop appropriate framework to assist KSA construction companies in integrating CSR fully into their business practices.

title: Structural Design and Analysis of High-Rise Building Using Ultra-Lightweight Floor System

description: Abstract - The main objective of this paper is to study feasibility of using ultra-lightweight (ULW) slab as an alternative design solution for floor component used in high-rise buildings. The main method is numerical case study by comparing the structural performances of 60-storey building in which floor component designed using one type of ULW called cross laminated timber (CLT) relative to floor component designed using conventional reinforced concrete (RC) slab using ETABS. The structural performances were compared between the two types of floor system including: total drift, inter-story drift, and base reaction which results in smaller frame sections and less reactions for the foundation demands by using ultra-lightweight (ULW). Additional study in term of survey to assess the awareness level of the public and engineering professionals about general high-rise building demand and new alternative building materials such as timber and its potential application in Saudi Arabia was also conducted.

title: EFFECT OF HEIGHT AND ORIENTATION OF INTERFERING BUILDINGS ON WIND LOADS ON TALL BUILDINGS

description: The research work presented in this paper investigates the effect of interference on wind loads on a tall building (instrumented building) having rectangular cross-sectional shape due to the presence of two interfering buildings close to the instrumented building. The effect of interference on the instrumented building is studied with the variation of height and relative orientation of the interfering buildings with respect to the instrumented building. Wind tunnel experiments are undertaken using five component force balance load cell and the results are reported in the form of X-Y plots. The effect of interference in both shielding as well as enhancing the wind load on the instrumented building, is seen to increase with the increase in the height of the interfering building. Negative drag force is also observed in few cases where shielded part of the instrumented building is large. Value of torsion on the instrumented building is observed to be as high as ten times of that in the isolated case.

title: ASSESSING THE BEHAVIOR OF COLUMN-SPLICE CONNECTIONS BETWEEN CFSTS IN AXIAL TENSION

description: Increasing the sustainability of construction materials is a key goal in the construction industry. As the demand for high-rise residential structures grows, new more efficient methods of achieving sustainability are required. Rendering larger structures demountable to enable the re-use of steel structural members is one solution. The aim of this study was to investigate and assess the behaviour of blind bolted column-column connections between concrete filled steel tubes in axial tension. The investigation aimed to address the need for accurate design guidelines for tensile members in the composite design standards such as Eurocode 4 and encourage the use of column-column connections in large-scale demountable structures. A numerical investigation of the blind bolted column-column connection has been performed using ABAQUS. The model consisted of two concrete filled square hollow steel sections connected using sleeve plates welded to the top tube only, as well as 16 M20 Lindapter Hollo-bolts connecting the tubes. The numerical investigation revealed that the sections tested conformed with AS1170.1 regarding columns in tension. Results of the numerical investigation have been compared against experimental results for a continuous CFST and it was found that the connections performed better in tension. The parametric analysis revealed no dependence of the shape of force-displacement relationships on diameter to thickness ratio, concrete compressive strength or yield stress.
