title: Feasibility, Value Engineering and Rock Fill Dams Construction: A Case Study

description: In this study details of structure of Shahr-e-Bijar CFRD in Guilan (a province in the north of Iran) and the reasons to select concrete-faced rock-fill are presented. To select CFRD first by investigation of 18 different types of dam based on local availability of materials and the ability of constructing by available technology (both Iranian and foreign available technology) six types of them were selected for value engineering. By attention to construction costs, execution time, durability, reliability and performance and ease of construction and operation; and also the importance coefficient for local government were selected for value engineering. After that 3 types of dam structure (vertical clay core dam, asphalt core dam, and cfrd) had maximum scores. Finally rock fill dam with concrete surface is selected because despite being more expensive in some cases than other options, it could be considered as a successful dam construction option in Iran because the construction needs no foreign technology and its technology of construction and materials are available. On the other hand the necessary time for the project is 24 months. The main objective of this project is to avoid time loosing because of materials availability and local technology that needs no finance transferring and no foreign contract that may not be affected by some political condition that delays the project.

title: BIOLOGIC STEP STIFFNESS SIMULATION OF TANGENCY JOINTS ON SHEET PILE LOAD TRANSFER INTO WATERWAY BED

description: The Irrigation project of Abadan will supply fresh water through the three flat dams in the NW of the Persian Gulf. Circular cofferdam is located in the Bahmanshir River upstream in 2007. Cell dam and ship lock walls will be constructed using sheet piling and PPM Pipe-Pin-Micro piles on the steel walls. Next step is required to design ship lock concrete bed. It should have compatible behavior with the sheet walls, micro piles and Gelatin concrete. The main purpose is transferred the extra bending moment of waterway impact from the sheet walls into the concrete bed. It is mentioned that steel walls and concrete bed will operate individually without any connections with each other. Also, tangency joints will resolve the problems such as structural bed connection and steel wall thermal enlargement. In addition the bed and walls must perform independently.

title: Professional Education for Design Management in the Context of Industrial Projects

description: Studies on developments in the Brazilian civil construction report there is still a disconnection between the design phase and implementation in addition to a lack of management and coordination of effective design. This frequent dissociation compresses the time and cost of a project development to be understood as an isolated instrument. In this context, it is understood that the academy significantly influences the practices exercised by professionals in the labor market. The fragmented form of education currently adopted does not provide a collaborative environment, affecting the integration of the various agents involved in the development of the project and during the execution of the building. Thus, the main objective of this study is to evaluate the influence of vocational training in project management activities by applying a case study of a large project.As a result, it was observed that the company studied could have presented better management and coordination of the design process. Similarly, it could have reduced costs and project development time if it had applied an effective risk management to avoid negative impacts and losses. The conclusion was that management concepts provide important inputs to the professional training of construction agents.

title: Desired versus Realized Benefits of Alternative Contracting Methods on Extreme Value Highway Projects

description: Highway agencies choose alternative contracting methods (ACMs) to for a wide variety of reasons, primarily their potential for superior cost and schedule performance. Most literature focuses on these two factors by analyzing aggregate datasets covering a wide-ranging contract values. These analyses create two voids that this paper attempts to explore: (1) ACMs provide a wide variety of benefits, which cost and schedule performance alone do not identify; and (2) projects of differing contract values benefit differently. This paper investigates the selection criteria for ACMs and why US agencies chose ACMs for projects at the extreme ends of the cost spectrum (defined as projects at the upper and lower 10th percentiles for each delivery method) and what benefits are realized, above and beyond cost and schedule performance. These findings are presented through a survey of 291 US projects, interviews of sixteen US agency representatives, literature review, agency ACM manual content analysis.

title: Forecasting Conceptual Costs of Bridge Projects Using Non-Parametric Regression Analysis

description: The cost of bridge construction is influenced by numerous internal and external factors, making it very difficult to approximate. Years prior to a bridge project letting, state highway agencies (SHAs) must set a reliable budget for the proposed project, but the information available to them is very limited. Developing reliable cost estimates for bridge projects during the early pre-construction phases is very important and challenging for SHAs. This study employed a non-parametric regression analysis technique

title: Calculation of NORMAL CONSTRUCTIONTIME FOR BUILDING CONSTRUCTION PROJECTSWHILST CONSIDERING UNCERTAINTIES

description: Construction time has a major influence both on the cost-efficient execution of construction works and on the overall project outcome achieved by the client. Clients would do themselves a disservice if they specified short or extremely short construction periods for their projects. The same applies to time made available for project preparation, particularly for the design and tender stages. Any project that is poorly planned, tendered and executed under time pressure will adversely affect actual construction work but also the building

title: Analyzing Databases in the Taiwan Bridge Management System Using Big Data Approaches

description: This paper describes some preliminary results of this research. Before conducting a comprehensive big data analysis of the whole system of Taiwan Bridge Management System (TBMS), a pilot test was performed to explore possible outcomes. A total number of 34,099 records each having 305 fields of 24 bridges in a specific region were analyzed using the famous R software. The resulting correlations between inventory fields and deterioration of bridge components are categorized in three types: explicable, inexplicable, and irrelevant. For those inexplicable correlations, interviews with experts are found necessary in order to explore useful or meaningful maintenance information. Two more similar tests are also being planned for two groups of bridges that are nearby sea or solely in the mountainous area. In addition to the correlation between a specific deterioration and all existing inventory fields, other maintenance information such as frequently maintained components as well as their maintenance frequencies and costs, and other crucial relationships among fields in the TBMS are highly anticipated in this research in order to establish beneficial suggestions to the bridge maintenance strategies in Taiwan.

title: SPATIAL REGRESSION ANALYSIS FOR MODELING THE SPATIAL VARIATION IN HIGHWAY CONSTRUCTION COSTS

description: Price volatility in wages, materials, and equipment has a significant impact on highway construction costs. As the construction market and economy have experienced dynamic changes in prices, the price volatility becomes less predictable. In addition, various levels of the price volatility in different market locations aggravate the prediction. Transportation agencies face significant uncertainties in price volatility across different geographical locations. This volatility may not be uniformly distributed across different geographical locations due to changes in the availability of local contractors, materials, equipment, and labor. The objective of this research is to develop statistical models that are capable to explain spatial variations in submitted unit prices for asphalt line items in highway projects considering local market condition factors. Historical bid data used in this research consist of resurfacing and widening projects let in the state of Georgia, the United States, between 2008 and 2015. The methodology of this research is a spatial regression analysis to explain the spatial variation in the submitted unit prices for asphalt line items. The findings of this research indicate that volatility in submitted bid prices is not uniformly distributed across different geographical locations within the same transportation agency. The contribution to the body of knowledge of this research is an improved understanding of the role of local construction market and macroeconomic conditions to explain geographic variability in construction costs.

title: Genetic Algorithm Optimization of Multiple Resources for Multi-Projects

description: Optimization of resources is very important in all construction projects. Project managers have to face problems regarding management of cost, time and available resources for single projects. This is more challenging when managing multiple projects. Most of the recent studies focused on optimization of resources for a single project, or a single resource. This paper presents a numerical model of multiple resources optimization for multiple projects using Genetic Algorithm. Most of the companies in the construction industry optimize the resources for single projects only. However, with the presence of several mega projects in several developing countries running at the same time, there is a need for a model to enhance the efficiency of available resources, and decreases the fluctuation as much as possible and try to maximize the use of the available pool of resources. The proposed model is user friendly, and it can optimize up to nine resources in three different projects running at the same time. The model is used on the identified critical resources. It calculates the cost of each resource, minimize the cost of extra resources as much as possible and generate the schedule of each project within a selected overall program.

title: Influence of baseboard height on wind force of scaffolds at building edge

description: When scaffolds are installed in construction sites, their resistance against wind force needs to be calculated. Japanese design guidelines require a specific scaffold resistance against wind force, but such rules and regulations are applicable solely to old-style scaffolds. A number of risks are inherent in the existing guidelines. First, new-style scaffolds are used in construction sites without practitioners knowing whether the design guidelines are appropriate for modern building components. Second, scaffolds are set near buildings, but workers are unaware of the effect of the wind force at the building edge. Finally, conventional designs feature the use of baseboards as scaffold components. While considering the aforementioned issues, a wind tunnel test was carried out as part of this study to examine the wind force exerted on scaffolds erected near a building edge. The parameters used in the test were baseboard height and the distance from the building edge. From the results, when the distances between the building

title: Design for Safety Knowledge-Based BIM-Integrated Risk Register System

description: Safety is a major challenge in the Construction industry. Researchers have shown that many construction fatalities could have been avoided with proper design considerations. Design for safety (DfS) knowledge helps designers to identify how their design may pose a risk during the life cycle of a building facility. Hence, designers can use DfS knowledge to address these safety issues in the design phase. Nevertheless, identified risk and required mitigation of the risk must be noted in a risk register. Moreover, all the risks cannot be addressed or eliminated during design. Hence, residual risks must be addressed during actual construction, operation and maintenance. This study proposes a DfS knowledge-based risk register system that registers design deficient risk with mitigation action and the residual risks that must be addressed during actual construction. The risk register is integrated with the BIM so that the residual risks can be easily visualized in BIM compliant 3D model for further action in later phases. A structure of risk identification procedure incorporating DfS knowledge is described. Identified risks are stored in a database. Mitigation action along with residual risks and responsible persons/parties for a design element are linked with the BIM model. Such early identification of hazard would be very useful to be prepared for any potential risk in advance which can save significant time and cost for the constructor.

title: Comparison of Cooling and Heating Requirements Between Brick Veneer and Fibro Cement Walling System

description: Space cooling and heating in residential sector is significant contributor to energy consumption in Australia. Therefore, it is important to reduce the cooling and heating requirements. The selection of a good walling system helps to save energy by homes. This research compared the thermal efficiency of a modern house (constructed using brick veneer walls with concrete floor slab) with an old house (constructed using fibro cement walls raised timber floor) using the AccuRate simulation tool. A standard house with two living rooms, one kitchen, one laundry and four bedrooms are simulated in a Sydney Suburb in Australia. It was found that modern house showed lower inside temperature variation than the old house all year around. The results also showed that the modern house has a lower energy consumption for space heating and cooling than the old house. The annual energy use for space heating and cooling in both the modern house and old house were 5197 kWh and 15,712 kWh respectively. Moreover, the annual energy costs were found to be $1,403 and $4,242 respectively for modern and old houses. The modern brick veneer house saved about 33 % of energy compared to old old house. When the net present value of the energy cost for f both houses over 50 years is computed, the energy cost of modern house was found to be $25,629 while it of old house is was $77,488 for the old house

title: PRESERVING TRADITIONAL CONSTRUCTION TECHNIQUES AND MATERIALS, AS AN ANSWER TO FUTURE ENERGY-FUEL CRISIS

description: Once a highly skilled and experienced professor told us: the future of architecture is in its hand craft past. We were not able to completely understand him at that time. Looking forward to the future where architecture and engineering professionals will perform facing energy fuel crisis and global warming, an endogenous approach, working with what is available, may be a subsistence tool. Preserving and further development of traditional construction materials, methods and techniques now has become a must, not form the cultural heritage stand point but as a survival instrument. In this paper we will analyze three different roofing systems, two of them ancestral techniques; toquilla leaf roof and straw thatch roofs, using them in real contemporary construction circumstances by incorporating them into the professional life through real construction projects and the educational system through Con lo que hay, a design-build class room in architectural school in Ecuador, facing them with conventional zinc metal roofing. This study will show the impact of recovering these techniques and materials within the academic, the professional, scientific development and on the local economies.

title: WORKING WITH WHAT IS AVAILABLE, TO DEVELOP LOCAL KNOWLEDGE TO SUSTAIN FUTURE DEVELOPMENT IN CRISIS SITUATIONS

description: This past April 2016 the coast of Ecuador suffered a devastating 7.8 earthquake. The automatic response was to run to the disaster area and help, not knowing that most of the time these unskilled volunteers became another casualty. Months later, government, universities etc. are working nonstop in order to responsibly restore the area. None the less, are we being efficient in order to prevent the possible effects of disasters to come? Almost 70% of Latin America is built on informality, and almost 80% of the destroyed and demolished infrastructure was due the lack of technical support. As professionals and academics, are we acting where it is necessary? A crisis creates opportunities, and knowing that most of Ecuador is in constant danger because of probable natural disasters, acting local may be more effective and can have a long lasting effect, rather than focus all the resources and effort in the disaster areas. These two academic case studies, one which took place just a couple of days after the earthquake which required immediate attention and the other several months later which required a local analysis, value the endogenous work in order to build a consciousness about our reality as a stronger service than simply rebuilding.
