Green Building Effect in Commercial Building vivatechijri
The key reason behind any environmental strain is the haphazard usage of global natural resources leading to, pollution in the environment, sea level rising, warming the earth, depletion of natural resources etc. The drastic climate variation has been observed worldwide, which in fact is mainly due to the release of CO2 from every energy actions. The building sector consumes nearly 40 % of the total energy and accounts for 30 percent of world greenhouse gas emissions. With all the green features modeled, the project building could achieve 33.76% energy improvement over the baseline building in the present model. The formulated water conservation strategy includes recycled water from sewage, rainwater harvesting, metering and sub metering, and low flow fixtures. The maximum quantity of recycled water generated inside the building is 157.3 KL/month and the total saving of freshwater is 53.85%.
Productivity of Concrete Placement by Dumpers in NigeriaIJERD Editor
The impressive economic growth rate of Nigeria is weakened by towering poverty statistics attributable to low productivity on construction sites. While in-situ concreting operations are important to the construction industry, labour productivity is often crudely estimated or lumped together irrespective of placement method. This research aims at investigating the effects of site productivity factors in the most prevalent mechanized concrete placement method in Nigeria with a view to optimizing its usage. To achieve this objective, data involving 26 concrete pours extracted from a total observation of 167 concrete pours on Lagos building construction sites were analyzed using the multiple regression method. The results which were subjected to optimization analysis using the Microsoft Excel spreadsheet package indicated that major productivity increases could be achieved with efficient scheduling of dumper concreting operations. Further research into the effects of other productivity factors using simulation modeling is recommended to establish optimal situations for a wide range of operating conditions that can be used to provide estimating and planning information for planning engineers on construction sites.

Finally the study suggested that what are the importance of risk function and project risk management for project success.
Risk Management in High Rise Construction Projects: A ReviewA Makwana
This paper gives information about identification of risk factors and perceptions of Indian construction practitioners i.e., contractors, owners, project managers and Engineers on the importance of different construction risks and how the risks should be assigned between the different parties of the contract. As the very common project styles, construction projects have so many characteristics likewise time limitation, specific items, financial restrictions and requirements, extraordinary structural and legal situations, complexity features. For this situation every construction project has own complex method. Risks constantly happen at construction projects and frequently cause time overrun or cost overrun. If you don’t contemplate these risk factors, or neglect the main factors, these risk factors will affect the damage because of the managerial errors. Risk management is the process which covers to identify the risks, for assessment with the help of qualitatively and quantitatively, to response with appropriate technique for management and controlling. The concept has gain popularity in various industries. Various companies frequently found the method in their projects for upgrading their performance, reducing their losses and increasing their profits. Questionnaire survey among clients, contractors, engineers and architects is analyzed using, Relative Importance Index (RII) and Importance Index (IMP.I) methods. The focus of this study is to understand what Risk Management is, understand the process of risk management at construction project and have depth knowledge on the use of risk management in high-rise construction projects.
Risk Severity Framework for a BOT Highway ProjectIOSRJMCE
Adequate attention needs to be given to project risk management for reaping the benefits by way of meeting the objectives of an organisation. Organisations which implement good risk management practices derive maximum advantage by way of fewer risks which are quite manageable in general and more so in infrastructure sector which is subjected to plethora of risks. The role of infrastructure in the overall development of a nation cannot be underscored. Considering this, a study has been carried out for an ongoing highway project being executed in the state of Telangana (India) under NHAI. The study was carried out by administering the questionnaire to 250 experts associated with highway sector and the response received was 110. The respondents were asked to identify the risks in four phases of a project namely Feasibility phase, Development Phase, Execution Phase and Operation phase and also the likelihood and impact of each of the identified risks. The severity of risk was determined based on the likelihood and impact of risks and was categorized accordingly. The severity of risk indicates the extent to which the project is exposed to that particular risk and the mitigation measures need to be taken accordingly to minimise the effect of risk

The Identification of Risks and its Criticality in the Nigeria Construction I...Dr. Amarjeet Singh
Failure in project delivering can be attributed to many risk events in the Nigerian Construction Industry. This risk could be as a result of the dynamic, sensitivity, and complexity of the construction Industry towards its environment, socio-political, economic, technology, and cultural variables in Nigeria. Nevertheless, the low level of Risk Management in Nigeria construction Industry, and the little understanding and knowledge of the subject by Project Stakeholders prompt this study.
A quantitative method of research was carried out, and among the sixty (60) questionnaires administered to clients, consultants, and contractors in the Nigerian construction industry, thirty-one (31) valid responses were obtained. The questionnaires were designed on the twenty (20) types of risks that were identified by construction professionals which were categorized into five namely; Government and Politics; Finance and Economical; Management and Technology; social and Cultural; Natural and Environmental Risks. And, findings made revealed that economic and financial risks surpass all other types in the Nigeria Construction Industry.

The focus of this study is to understand what Risk Management is, understand the process of risk management at construction project and have depth knowledge on the use of risk management in high-rise construction projects.
Risks have a significant impact on a construction
project’s performance in terms of cost, time and quality. As
the size and complexity of the projects have increased, an
ability to manage risks throughout the construction process
has become a central element preventing unwanted
consequences. How risks are shared between the project
actors is to a large extent governed by the procurement
option and the content of the related contract documents.
Therefore, selecting an appropriate project procurement
option is a key issue for project actors.
The overall aim of this research is to increase the
understanding of risk management in the different
procurement options: design-bid-build contracts, designbuild contracts and collaborative form of partnering. Deeper
understanding is expected to contribute to a more effective
risk management and, therefore, a better project output and
better value for both clients and contractors. The study
involves nine construction projects recently performed in
Sweden and comprises a questionnaire survey and a series of
interviews with clients, contractors and consultants involved
in these construction projects.
The findings of this work show a lack of an iterative
approach to risk management, which is a weakness in current
procurement practices. This aspect must be addressed if the
risk management process is to serve projects and, thus, their
clients. The absence of systematic risk management is
especially noted in the programme phase, where it arguably
has the greatest potential impact. The production phase is
where most interest and activity are to be found. As a matter
of practice, the communication of risks between the actors
simply does not work to the extent that it must if projects are
to be delivered with certainty, irrespective of the form of
procurement.
A clear connection between the procurement option
and risk management in construction projects has been
found. Traditional design-bid-build contracts do not create
opportunities for open discussion of project risks and joint
risk management. A number of drivers of and obstacles to
effective risk management have been explored in the study.
Every actor’s involvement in dialogue, effective
communication and information exchange, open attitudes
and trustful relationship are the factors that support open
discussion of project risks and, therefore, contribute to
successful risk management.
Based on the findings, a number of recommendations
facilitating more effective risk management have been
developed for the industry practitioners.
Evaluation of Risk Factors Affecting Cost Performance of Construction Project...IJCMESJOURNAL
Effective management of risk is critical to the success of any construction project. The importance of risk management has grown as projects have become more complex. Contractors have traditionally used financial mark-ups to cover the risk associated with construction projects, but as competition increases and the margins become tighter, they can no longer rely on this strategy and must improve their ability to manage risk. This study has carried out an empirical evaluation of the effect of risk factors on cost performance of projects at delivery. The study is based on the analysis of primary data derived from bills of quantities for the construction/erection of hospital projects by the Ministry of Works and Housing, Jalingo in Taraba State. The obtained data was analyzed using linear regression, t-statistics, F-statistics, line and scatter graphs. The study identified the following risk variables as having significant impact on cost performance: project size, project location, project complexity, level of variations, prime cost sums and provisional sums, estimator bias, market conditions, level of competition, fraudulent practices, construction techniques, economic and political factors, construction accidents, health and safety factors. The study concludes that these factors have to be comprehensively assessed in the light of the individual projects. It recommends among others, the need for a departure from the use of traditional approach of percentage risk adjustment factor to a more comprehensive risk management system.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
