title: BOND AND SHEAR-STRENGTHENING PERFORMANCE OF FRCM COMPOSITES

description: This paper is aimed at studying the bond and shear-strengthening performance of fabric reinforced cementitious matrix (FRCM) systems. Three FRCM systems were compared, namely, polyparaphenylene benzobisoxazole (PBO)-FRCM, CarbonFRCM, and Glass-FRCM. At first, six double-shear specimens were tested to investigate the FRCM/concrete bond, with the test variables including the fabric type and the bond length. After that, seven shear-critical reinforced concrete (RC) beams were tested under three-point loading, considering the fabric type and strengthening configuration (full/intermittent) as the test variables. As for the double-shear test results, the failure observed was fabric/matrix debonding in carbon-FRCM, matrix/concrete debonding in PBO-FRCM, and fabric rapture in glass-FRCM. The FRCM/concrete bond increased with the bonded length, and the PBO-FRCM showed the highest bond to concrete. Regarding the RC beam tests, the FRCM-strengthened beams showed the same failure mode that is debonding at the FRCM/concrete interface. Nonetheless, FRCM had successfully strengthened the beams in shear: an average gain of 57% in the load carrying capacity was achieved as compared to the non-strengthened reference. Indeed, the full-length strengthening resulted in a better structural improvement compared to the intermittent-strengthening configuration. Amongst the three systems, carbon-FRCM systems were the most efficient in shearstrengthening RC beams.

title: BUILDING A SUSTAINABLE WORLD: ECONOMY INDEX OF GEOPOLYMER CONCRETE

description: Geopolymer concrete offers a considerable solution not only to the environmental problem but also to the structural deterioration confronting the world. But, limited or no study is found on its cost implications. Consequently, this study evaluates the production cost and the economy index of geopolymer concrete (GPC) and compares it with the Portland cement concrete (PCC). Corncob ash (CCA) and ground granulated blast furnace slag (GGBFS) were used as source materials in the production of geopolymer concrete. Alkaline liquids were prepared to obtain 12 molar concentrations. The concentration was used to activate the source materials. Grade 30 concrete (M30) was adopted as a mix design proportion. GGBFS was replaced by CCA in varying percentages as 0%, 20%, 40%, 60%, 80%, and 100%. The research findings reveal that GPC is 27.71% lesser than the PCC in terms of production cost while the economy index of GPC is higher than the PCC for the same grade of concrete. The results infer that GPC is cheaper and more viable than the PCC. Thus, geopolymer concrete proves to be an innovative product and appears to be a feasible solution not only to the environmental and structural deteriorating problems but also to the problem of high cost of Portland cement in the construction industry.

title: BUILDING COST INFORMATICS WEB-BASED NEURAL NETWORK-REGRESSION HEURISTICS PROTOCOL FOR DECISIONS IN BUILDING CONSTRUCTION PROJECTS

description: Building Informatics is a body of knowledge that uses ICT computer system, digital system, building information modeling and state of art software in solving technical and management issues in building and construction fields. The data was generated through the combination of parametric regression method and neural network (an expert system). One of the modern methods used in data forecasting and modeling is Artificial Neural Network considering its advantage over traditional regression method. Data sample of One thousand and five hundred (1500) residential building projects completion costs, out of original data trained with an Artificial Neural network were selected at random and divided into two half as sample for the study
description: one part was used to generate the network heuristic algorithm while the second part was used in modeling and simulation of the system for model validation. Regression analysis was carried out and model validated with functionality and Jackknife re-sampling technique. 150 Questionnaires was used to capture data on factors influencing application of heuristics protocol for decisions in residential building construction projects and data samples were analyzed using severity index, ranking and simple percentages. Analysis of data brought to the fore some factors that influences effective application of heuristic protocol in solving decision problems in construction decision process. The linearity analysis was carried out on the model and results indicate high level of tolerance and - 0.0876 lowest variation prediction quotients to 0.9878 highest variation quotients. Also 0.069 regression model fitness coefficient (R-square) was generated with 0.9878 highest variation quotients with standard error of 0.045. The results data attest to the stability of the model generated and the model is flexible in accommodating new data and variables, thus, allows for continuous updating

title: BUILDING INFORMATION MODELING AND OPERATION

description: The research project "BIM-based operation" contributes standardization and uniform understanding of the BIM process and the resulting changes in the construction and real estate sectors. The project develops an ideal-type target process chain, based on an actual process analysis, for using the BIM method in real estate operations. A standardized life-cycle process is intent to show required information for operation actives in concrete terms. Based on this, information and communication interfaces can be identified to analyze changing performance requirements of the parties involved, and open questions such as legal issues can be further elaborated or dealt with. Based on literature research and numerous expert interviews, it analyzes and determines how individual process steps are carried out and which parties need to deliver what kind of information to which participant at what time, to fulfill build owners' requirements to a successfully constructed and managed building. The focus is thus on the exchange of information between those involved in the operation phase. Existing standards are consciously integrated into the development. Companies, institutions, and other stakeholders are thus given an overview of the situation in relation to the important exchange of information. In particular, the real estate operating phase is attributed to a high optimization potential through digitization.

title: BURIED TRANSPORTATION STRUCTURES: FUZZY-MARKOV COMPUTATION CASE STUDY

description: This paper will focus on how to improve buried structures' resilience and sustainability so that they hold up over time, withstand extreme weather events, and minimize the use of natural and financial resources. Generally, buried Transportation structures are those which have some portion of their elements and configuration dormant, such as culverts, bridges, and their foundation systems. These structures are a significant part of transportation networks and their related systems. These structures can be disrupted by extreme weather events such as seismic activities, extreme wind gusts, tornado, and tropical cyclones. Repairing the damage after such events can challenge resources and negatively impact the area's economy by disrupting traffic. Moreover, a common problem with buried structures is the lack of understanding about each individual structural element. Accordingly, as a part of this paper's focus, careful attention is given to such important structural integrity. Nevertheless, a number of Australian case studies were undertaken to further improve the buried structures' resilience and sustainability. To support this paper's aim a Fuzzy-Markov computation using a modified FuzzyStatProb for buried assets were also explored. The Fuzzy-Markov computation accurately identified the appropriate treatment regimes for selected bridges
description: which ultimately reduced the natural and financial resources usage.

title: CASE STUDY COMPARISONS OF THE ECOLOGICAL FOOTPRINT ON SOCIAL HOUSING AFTER EARTHQUAKE

description: This research seeks to distinguish which factors influence the ecological footprint and what types of construction have the least environmental impact in a post-disaster social housing building. The first case study is a government social housing design, built with bamboo and concrete masonry blocks, and another design by Ensusitio, a private practice approach to social housing built with bamboo and earth. These houses were granted to victims of the April 2016 earthquake in the Ecuadorian coastal region. The investigation process was carried out based on primary research, which was used to understand how Ensusitio carried out the construction process of Meche's house and also based on a secondary investigation of government social housing. With this information, a comparison is made between them to determine which of the two has the least ecological footprint.

title: CASE STUDY OF 3D SEISMIC PUSHOVER ANALYSIS OF INTEGRAL ABUTMENT BRIDGE

description: Integral abutment bridges (IABs) have a continuous deck monolithically encased into abutment stem, and typically using single row of piles to carry vertical loads and accommodate longitudinal thermal deformation. Except for smooth pavement and low maintenance cost, IABs have also outperformed conventional seat-type abutment bridges in seismic performance due to increased redundancy, higher damping, and smaller displacements. However, lack of information on their seismic design and performance may have discouraged their use in high seismic zones. In this study, current research and implementation of IABs are comprehensively reviewed. IABs with steel-concrete girders provided by NYDOT are chosen for intensive seismic case study. Three-dimensional finite element models of IABs for nonlinear seismic analysis are elaborated to capture the behavior of components of superstructure, abutment stem, piles, backfill, etc. Pushover analyses are carried out to obtain the capacity curves. Through parametric studies, the effects of bearing are outlined. Conclusions and some recommendations are made for seismic evaluation and design practice of IABs.

title: CHALLENGES AND RISKS RELATING TO MEP ENGINEERING IN LARGE BUILDING CONSTRUCTION PROJECTS

description: MEP (mechanical, electrical, plumbing) systems are integral parts of modern buildings. Adequate conception, design, and installation of MEP systems are an essential prerequisite for a successful project. Experience has shown that the practical implementation of this aspect is often a challenge for the involved project stakeholders due to the increasing complexity of MEP systems. This raises the question of whether the field of MEP engineering is particularly sensitive to potential conflicts and disruptions in complex construction projects compared to other trades. In order to investigate these questions, a survey based on a standardized questionnaire was carried out among Austrian experts with experience in large building construction projects. Overall, 515 experts participated in this survey, with 365 completely answering the questionnaire. The results show that the participants consider proper project integration of MEP engineering as a critical success factor in complex construction projects. They also show that inadequate consideration of this aspect poses a substantial risk for project disruptions.

title: CHALLENGES HINDERING THE ATTAINMENT OF SMART CITIES

description: The concept of smart cities has become a buzzword in most developing countries. Most professionals within developing countries are quick to adopt this idea in their every day discuss on developing the state of their nation, without actually considering what this concept means to the average individual on the streets. Even lesser consideration is given to the readiness of these developing nations in terms of adopting the concept of smart cities. It is based on this notion that this study, through the review of existing studies, assessed the readiness of cities in Nigeria in adopting the concepts needed for achieving smart cities. The study gives an insight on the challenges impeding the attainment of city smartness in the country. It was observed that solving the problems caused by rapid urbanization within cities is the first step towards making these cities "smart ready". Therefore, if cities in Nigeria are to attain city smartness, first looking inward and solving the endemic problems within these countries is necessary before adopting concepts of smart cities that have been mastered in developed countries. Although the submissions of this paper form part of a much larger ongoing study, it contributes to the body of knowledge as it brings to light the challenges that must be solved if cities in Nigeria are to ever become smart.

title: CHALLENGES OF USING NON-DEGRADABLE WASTE MATERIAL POLYSTYRENE PACKING IN REINFORCED CONCRETE DESIGN AND CONSTRUCTION

description: Weight and Environmental concerns are two elements that have made the search for alternative materials of construction critical in today's construction industry. The importance of finding a solution to the problem has given rise to the use of nondegradable materials. This study examines the challenges of making such material as polystyrene used in product packaging a part of the structural element in construction. Such adventure it is envisaged reduced the volume and number of landfill sites in Nigeria where air pollution arising from dump sites affects the health of citizens. To achieve this aim, Styrofoam was used as a partial replacement for coarse aggregate (granite) by volume. The replacement was carried out in varying percentages of 10, 20 and 30% Styrofoam concretes respectively with a concrete mix ratio of 1:1:2. The result obtained showed that concrete produced using Styrofoam as the alternative aggregate possess lesser values of compressive strength when compared with the control of conventional concrete without Styrofoam. The optimal percentage of a replacement for Styrofoam concrete was 10% with a compressive strength of 21.33 N/mm2 while the control concrete had a compressive strength of 33.26 N/mm2 . The loss of strength of Styrofoam concrete is compensated by the reduction of the requirement for landfill sites and the attendant pollution generated while the concrete can be used for non-structural elements in construction.

title: CHANCES AND RISKS OF COMBINED PRICING

description: Appropriate costing creates a plausible, reliable basis for determining the bid price. One of the key requirements that applicable laws, standards, and guidelines stipulate for (structural) specifications is that works should be specified clearly, completely and objectively so as to ensure bid comparability. Furthermore, cost estimates should be possible for the specified works (excluding non-quantifiable risks). The specifying party usually requires combined pricing because works related to various structural components, construction trades, subsoil types, rebar diameters etc. that necessitate a variety of types and combinations of production factors are merged into a single item. Combined pricing occurs whenever a unit price is to be derived from different cost estimates with respect to the utilization of production factors. This means that bidders intending to develop an activity-based costing model would have to know the type of work or service, the underlying conditions for performing the work, and the associated timeframe (i.e. project start, binding milestones, project end). This paper investigates if combined pricing items meet these requirements whilst putting a particular focus on the relevance of combined pricing to construction management and economics, including construction expert opinions on the chances and risks of this approach. For this purpose, this paper primarily deals with reinforcing works.

title: CLAYEY SOIL TREATED BY CEMENT AND QUICKLIME BY MICROSTRUCTURE: A MINERALOGICAL ANALYSIS

description: Soft clayey soil was treated by a combination of cement (PC) and Quicklime (LQ) in order to modify and stability. This study shows an improvement of clay soil brought from Garma Ali site in the Al Basra governorate, Iraq. The PC was added in percentages of 0, 2, 4, 6, 8, and 10%, and LQ was added to 2 and 4%, of dry weight. Also, this research used Microstructure Analysis by Scanning Electron Microscope (SEM) testing and Mineralogical Analysis by X  Ray Diffraction (XRD) testing on the examination soil treated with mix between cement (PC) and Quicklime (LQ) for the purpose of knowing the reasons for the increase in the shear strength and decrease maximum dry density. Through the micrographs that result from the scanning electron microscoping and the curves of X-ray that demonstrate presentence, the formation of the hydration reaction product (CSH gel) shows tiny bristle (rod) crystals. The CSH gel and the tiny bristle (rod) crystals worked on coating and contact the particles together. The micrographs for soils treated with (2% LQ + 10% PC) show an increase in the amount hydrated gel (CSH) compared to the soil treated with 6% PC and 2% LQ and 8% PC and 4% LQ, but the number of bristlelike crystals decreases compared to soil treated by 8% PC and 4% LQ.
