title: KEY KNOWLEDGE ENABLER FACTORS FOR EFFECTIVE BIM IMPLEMENTATION IN CONSTRUCTION ORGANIZATIONS

description: Building information modeling (BIM) is an innovative approach that is widely used to overcome various challenges in the construction industry. Current BIM implementation mainly focuses on information management, but puts very limited effort on knowledge. That is, the current BIM practice is information-centered, but it is not mature enough to generate and capture experiential knowledge. In addition, knowledge management (KM) is limitedly adopted for BIM implementation. Based on this paper's rigorous literature review as well as a survey questionnaire, nine knowledge enablers and 52 knowledge enabler factors for BIM implementation (KEFBIs) are identified. In this paper, we deploy ISM fuzzy MICMAC to identify and classify the key KEFBIs that influence BIM implementation by contractors. The results can guide contractors to avoid difficulties while adopting BIM so that they can plan and allocate their resources optimally.

title: KNOWLEDGE ENABLED TECHNOLOGY SELECTION FOR SEWER CONDITION ASSESSMENT

description: To improve the quality of life of communities, local government provides municipal services, including the sewer collection, effectively and efficiently employing asset management best practices. The condition assessment of assets (including the sewer collection system) is one of the core elements of implementing effective asset management across the utility organizations. Availability of sophisticated and complex condition assessment technologies, lack of common understanding about them and related high cost associated with sewer condition assessment requires the technologies and related knowledge to be explicitly defined in a neutral formatthe ontology, to support the development of applications for technology selection. An ontology of condition assessment technologies for sewer network, CATS_Onto was developed following a seven-step approach at two levels of abstraction: meta-model and detailed ontology. This paper presents the development and verification of the meta-model. The proposed ontology will be used to develop a tool for the selection of the most appropriate technology for sewer condition assessment. The knowledge representation was verified while validation is underway.

title: LIFE CYCLE COST ANALYSIS OF ENERGY EFFICIENT SINGLE FAMILY RESIDENCE

description: Residential and commercial buildings account for more than half of the electricity consumption in the United States. There are numerous practical solutions to make buildings more energy efficient and sustainable. Although it is well-established that green buildings are socially, environmentally and economically beneficial, there is still a lack of green buildings in the residential sector. The installation and upfront costs for these houses are very high. This research aims to facilitate a broader understanding of the cost benefits of energy efficient and sustainable residences. The Life cycle cost analysis (LCCA) approach and energy simulation tools have been utilized and integrated for assessing the traditional single-family residence in the United States. A comparative study has been carried out including passive and net-zero energy through energy simulation software. This analysis will benefit academic researchers and industry practitioners to analyze and evaluate challenges and opportunities in energy efficient and sustainable residences.

title: LOAD BEARING STRUCTURAL ASSEMBLY

description: This article is based on an invention focused on absorbing and redirecting forces two dimensionally or three dimensionally in any mechanism that relies on force resolving members, so more benefits of the mechanism can be achieved. This Assembly is focused on new ideas for framing and connections to resolve forces so the rigidity between members can be minimized and the Assembly can sustain performance under longer durations and more unique loadings, i.e., seismic loading on structure. The Assembly uses several techniques and fundamentals for efficient force dissipation with, or without deflection while creating a controlled rotation when loaded. The allowable arrangement of the Assembly within itself (web members within outer and inner rings and arcs), and as an assortment of assemblies, can be limitless. This arrangement, configuration of web members, numbering, width and flexibility, can be arranged for a predictable and controlled deflection or rotation in any direction, due to loading from any direction and type, thus creating a load bearing and load dissipating Assembly with greater efficiency, and advance the life of interacting parts under loadings, i.e., seismic loading of structures. This Assembly, in particular the web members, can be an arrangement and properties of arcs to offer a desired response, as well as create a rotation when loaded.

title: LOAD PATH REFORMULATION AROUND MULTIPLE RESTRICTIONS FOR AN INDUSTRIAL RETROFIT

description: Process, operational, and electrical restrictions inherent in the design of a regulatory compliance upgrade for an industrial plant, and overburdened existing structure, required an unusual structural retrofit. There were multiple restrictions on placement of structural members and multiple needs for additional strength in the existing members. To manage the constraints, the load path was reformulated to bypass problem areas and focus upgrade work on just a few locations. The key in selecting upgrade locations was determining where there was reserve capacity in the existing foundation. Two such locations were identified and super-bents were formed there using existing moment frames. Horizontal trusses were built to bridge between the super-bents. A super-bent included a new grade beam, with end bulbs surrounding existing column pedestals, column section augmentation, new heavy anchor bolts and new diagonals to convert two parallel beams into a deep truss. Embedded structural steel was utilized in the grade beam end bulbs to distribute anchorage forces and develop reliable load paths around obstructed columns. Unusual uses of structural steel, work in obscured areas, unconventional structural systems and construction schedule interuptions led to an increase in construction management and inspection scope and complexity. CM lessons learned from the project involved better interaction of disciplines during design and greater input from engineering just prior to and during construction.

title: LOOKING FOR PROJECT SUCCESS IN INFRASTRUCTURE PROJECTS: HOW CAN WE ACHIEVE IT?

description: Even though the main aim of project management (PM) is to assure successful projects, the PM literature still lacks a clear definition of project success (PS), since it highly depends on the stakeholders' expectations and the point in time in which the project was evaluated. In this context and due to their specialties e.g. long duration or a large number of stakeholders, the infrastructure projects are subjected to time delays and cost overruns and therefore, criticized in the society and described as failed or unsuccessful projects. This paper hypothesizes the need to adapt our PM approach to follow more systemic methods and presents the main principles of systematic project management (SPM) as a success factor (SF) for infrastructure projects. In addition, a case study about the Gotthard Base Tunnel is presented to verify the literature findings.

title: MACROMECHANICAL ANALYSIS OF SPHERICALLY VOIDED BIAXIAL CONCRETE SLABS

description: The use of spherically voided biaxial concrete slab (SVBS) system, which uses hollow plastic balls as infill material, has increased widely because of its reduced weight-tostrength and weight-to-stiffness ratios when compared to solid concrete slabs. However, SVBS is a heterogeneous composite structure in which building a representative continuum model poses a significant challenge. To mitigate this challenge, the feasibility of determining the macromechanical structural behavior of spherically voided biaxial concrete slabs is studied using plate theories, aided by mechanical properties that were determined from a homogenization process of the representative volume element (RVE). This paper presents numerical analysis results of SVBS using both Mindlin-Reissner (thick) and Kirchhoff-Love (thin) plate theories. The results from both theories predicted the slab behavior reasonably well and they were within 10% of each other with the exception of the prediction of the twisting moment. Possible explanation of this deviation is provided in the paper.

title: MAGNETIC FIELD TREATED WATER INFLUENCE ON STRUCTURAL CONCRETE ELEMENTS: ENVIRONMENTAL ISSUES OF CONCERN

description: The impact of magnetized water on the strength properties of concrete calls for a holistic appraisal of its effect on the environment of production and use. In this study, the influence of the Magnetic Field Treated Water (MFTW) on the strength of concrete produced under various environments is considered. The work considered three environments of use of magnetized water in concrete with respect to partial replacement of fine aggregate with waste glass
description: quality of curing medium on mechanical properties of concrete and effect on the mechanical properties of selfcompacting concrete. The three scenarios presented involved preparing and testing concrete cubes made with magnetized water, cement, fine (sand and glass) and coarse (granite) aggregates at various levels of combination and environment of curing. The concrete cubes were cured for 7, 14, 28, and 56 days and the strength and other parameters, such as slump and workability, were compared with conventional concrete in normal environment. It was observed that concrete under self-compacting concrete made with MFTW had a 9.1% increase in compressive strength than normal
description: for concrete made with clay brick powder and MFTW, both the workability and compressive strength was higher than normal. The magnetized water in concrete with waste glass as partial replacement had higher slump value and 24% increase in compressive strength than conventional concrete. MFTW therefore improves strength development of concrete.

title: MECHANICAL AND DURABILITY CHARACTERISTICS OF GGBS DOLOMITE GEOPOLYMER CONCRETE

description: Production of Portland cement causes global warming due to the emission of greenhouse gases to the environment. The need for reducing the amount of cement is necessary from sustainability point of view. Alkali activated and geopolymeric binders are used as alternative to cement. Industrial by-products such as fly ash, ground granulated blast furnace slag (GGBS), silica fume, rice husk ash etc. are commonly used for the production of geopolymer concrete. This paper focuses on the development of geopolymer concrete from slag (100% GGBS). Effect of different cementitious materials such as lime, fly ash, metakaolin, rice husk ash, silica fume and dolomite on strength properties of slag (GGBS) based geopolymer concrete are also discussed. It is observed that the addition of dolomite (by-products from rock crushing plants) into slag based geopolymer concrete reduces the setting time, enhances durability and improves rapidly the early age strength of geopolymer concrete. Development of geopolymer concrete with industrial by-products is a solution to the disposal of the industrial wastes. The quick setting concrete thus produced can reduce the cost of construction making it sustainable also.

title: MECHANICAL AND MICRO-STRUCTURE CHARACTERIZATION OF STEEL FIBERREINFORCED GEOPOLYMER CONCRETE

description: This paper aims to investigate the mechanical performance of steel fiber-reinforced geopolymer concrete made with fly ash and ground granulated blast furnace slag as blended aluminosilicate source material. To activate the binding phase, combinations of sodium silicate (SS) and sodium hydroxide (SH) solutions with three different molarities (8M, 10M, and 14M) were used. Steel fibers were added to the geopolymer concrete mix in varying proportions up to 3%, by volume. Constant binder, activator solution, and aggregate contents were adopted for all 13 mixes. Samples were cast and cured at ambient conditions for measuring the rheological and mechanical properties, including slump, modulus of elasticity, compressive strength, tensile splitting strength, and flexural strength. Experimental test results show that geopolymers made with higher molarity of SH were less workable but had improved mechanical performance. The effect of adding steel fibers on the mechanical performance was more apparent at early age and in weaker geopolymer concretes. Additionally, scanning electron microscopy, differential scanning calorimetry, and Fourier transform infrared spectroscopy highlighted the co-existence of calcium aluminosilicate hydrate and sodium aluminosilicate hydrate gels.

title: MECHANICAL PROPERTIES OF STRUCTURAL STEEL AND HIGH-TENSION BOLT AT ELEVATED TEMPERATURE

description: This paper presents the test results of the mechanical properties of three types of structural steel at high temperature, which are generally used for the Pre-Engineered Building (PEB) system. The PEB system is generally used for non-residential buildings, such as factories and warehouses. The structural steel members are installed without fire resistance protection, which means they are very weak in the case of fire. The end-plate connection could be critical in the case of fire because most of the moment is resisted by the tensile force of the bolts. Therefore, the mechanical properties of bolts at elevated temperatures are tested. Coupon test specimens for SS400(SS275), (SM490(SS355), and F10T bolts were tested according to ASTM E8M. The high-temperature coupon tests were performed at 20ฐC, 400ฐC, 500ฐC, 600ฐC, 700ฐC, and 800ฐC. The test results were compared with the design reduction factors obtained from the American and European standards. The yield strength and tensile strength satisfied the minimum strength of the specified standards at 20ฐC. However, the reduction factor for yield strength obtained at a high temperature was lower than that of the standard value suggested by the code. In particular, the reduction factors for the high-strength bolt (F10T) were lower than those of the structural steel members (SS400(SS275), SM490(SM355)).

title: MECHEดS HOUSE OR "BEING IN THE WORLD": A POST-DISASTER COMMUNITY BUILDING EXPERIENCE

description: On April 16, 2016, Ecuador had suffered a 7.8 earthquake. The experience designing and building of Mecheดs house, a post-disaster alternative building process, is analyzed in this paper applying Martin Heideggerดs concepts of Dwelling, Being in the World and Being There. These allow better understanding to the idea of housing in the community where the object is built, to visualize its most symbolic space, also it enables to see how the users of the built dwelling make it their own, the construction, form and materials despite that in the beginning of the construction process they did not accept them. This article tries to explain two questions: The house of Meche reflects its habitat: Where is it built? And how Meche, who is the homeowner, and the participants make the house and experience their own, in order to replicate the appropriate construction and resilience.

title: MICROSTRUCTURE INVESTIGATION OF SEAWATER VS. FRESHWATER CEMENT PASTES

description: Recently, seawater has emerged as viable mixing water for concrete, especially in the case of non-reinforced concrete applications or with the use of non-corrosive reinforcement. Previous studies concerning seawater-mixed concrete mostly revealed an initial slight increase in its strength performance (i.e., till Day 14 following mixing), followed by a strength reduction of 715% (i.e., after 28 days or longer) as compared to the conventional freshwater-mixed concrete. With an attempt to explain such observations, this paper aims at comparing the microstructure of freshwater- and seawater-mixed cement pastes. Scanning electron microscopy was utilized to observe the microstructure of freshwater and seawater pastes at Days 3 and 28 following mixing. At Day 3, seawater paste was observed to have more densified microstructure as compared to that of the freshwater counterpart, resulting in relatively higher strength performance. At Day 28, the microstructure was almost similar for the two cement pastes. However, seawater paste was observed to have salt impurities as a result of seawater ions, which possibly cause a slightly lower strength performance as compared to the freshwater paste.

title: MODEL ANALYSIS OF HIGH-RISE STRUCTURES FOR WIND AND EARTHQUAKE FORCES

description: The objective of the present work is to study and analyze the effect of wind and earthquake loads on a chosen symmetrical plan of a multi-storied building to assess the behavior of the structure in all the seismic zones based on IS 1893 and subjected to different wind velocities based on IS 875 codes. For the present study, six cases (6 floors, 9 floors and 12 floors each for earthquake and wind) are considered under which 30 structures are modelled in ETABSv16.0 software and static analysis is carried out. Structural parameters like story drifts, story displacements and story shears are studied. Finally, it is found that story drifts are found to be maximum at 2nd floor (i.e., at 6 m) and 40% increase is observed in parameters when wind speed is increased from 33 to 39 m/s and by 21% when wind speed is increased from 50 to 55 m/s. With increase in wind speed on moving to higher seismic zones, with increase in number of stories from 6 to 9 story drifts increased by 109%, story displacements increased by 185% and increased by 15% and 62% on moving to higher seismic zones. Also, wind forces on the structure subjected to variation in increasing wind speeds and increasing heights in zone II and zone III but in no case are they greater than the earthquake forces in zone IV and V.

title: MODEL DISASTER PREVENTION LESSONS IN PRIMARY SCHOOL BASED ON DISASTER PREVENTION EDUCATION POLICIES

description: This study deals with disaster mitigation education in primary schools and as a final goal aims to improve citizens' capabilities to mitigate disaster situations in society. This report summarizes the current national policy on safety education in Japan and follow it up with a summarization of the Tokyo Metropolitan Government policy, which is based on the national policy. In addition, it compares Japan's education policy with that of New Zealand. Analysis revealed the following three points. First, the content of safety education in Japanese primary schools consists of six fields (traffic safety, daily life safety, disaster safety, etc.). Just before, and after, the Great Tohoku Earthquake in 2011, the main educational content changed from daily life safety to disaster safety. Second, by focusing on lessons, it was found that the content of disaster safety was taught not as part of various subjects but largely during "homeroom activities". Third, it became clear that the subject of earthquakes now accounts for half of the disaster prevention lesson contents in Japanese primary schools and has been included in disaster prevention lesson contents in all school grades.

title: MODELING CONSTRUCTION ORGANIZATION PERFORMANCE IN POST-CONFLICT ENVIRONMENT

description: In the field of the construction industry, research work has widely focused on identifying Key performance indicators and critical success factors without assessing the impact of conflict environment factors. This study focusses on the impact of postconflict environment factors on local construction organization performance. This paper presents a framework for improving construction organization performance in a post-conflict environment. The proposed framework consists of four stages: identify post-conflict environment impacting factors, determine critical success factors (CSFs), determine key performance indicators (KPIs), and adopt the best strategy to improve performance. Analytical hierarchy process (AHP) and multiple linear regression (MLR) modeling has been used to analyze quantitative and qualitative variables obtained from the literature and expert opinion through comprehensive literature search, meetings, and survey to determine critical success factors and to identify performance improvement strategy. The study finding suggests that twenty factors from the questioner have a critical impact on the identified five performance measures. The presented CSFs helps the organization management team to consider the impact of these factors on their firm and to formulate a competitive strategy in a post-conflict environment.

title: MODELING CONTRACT PRACTICES RESULTING IN RISK MISALLOCATION

description: Risk misallocation has been a topic of discussion in the extent literature for some time now. The literature points out that risk management is the key to ensuring that optimal risk allocation is achieved. While the focus on risk allocation has been about the party best suited to carry a given risk, the issue of how misallocation occurs is rarely dealt with. This paper modeled how risk misallocation can result from contract practice. This was done through a literature review and 15 purposive heterogeneous semistructured interviews conducted with clients, project managers, architects, engineers and quantity surveyors in the Zambian building sector. The derived model suggests that misallocation could result from inappropriate selection of risk mitigation mechanisms provided for in the contract, poor selection of contracts and use of inappropriate procurement routes. These findings advance knowledge that necessitates the allocation of risk appropriately as the areas of contract practice and risk management are rarely researched with regards to risk misallocation.

title: MULTI-CRITERIA DECISION MAKING IN EARLY STAGE DESIGN: CAPTURING THE DYNAMICS USING UTILITY THEORY

description: This paper introduces a conceptual framework that captures the key processes in early stage design (ESD) processes mapping out Decision Making (DM) to support value delivery using utility theory. A lot of construction waste in downstream processes can be traced back to the design stage according to research. Yet there's currently little research into interdependences key to value generation in this most dynamic of construction processes. This research identifies the role of the end-user as a key element in the process of value generation in ESD. Understanding the user requirements is just as important a step as it is for the design process to engage in requirement forecasting. This paper explores new ground in understanding of DM processes in ESD in defining and understanding value. The research first explores the theoretical concepts in multi-criteria DM, UT and value generation in ESD. Design science research methodology is used to review literature to inform the framework that's validated with case studies in two design firms.
