Evaluation of Factors Affecting Professional Services Of Consultancy Firms in Building Projects
No full textThis study is aimed at achieving improvement of service delivery through identification and establishing of main factors affecting professional services in the building industry. Questionnaire was used to elicit information about their perceptions of the factors affecting services from professionals who are involved in on-going and/or recently completed clients’ building projects. Purposive sampling was used to select the population of the study. The Mean Score(MS) was used to rank the factors as perceived by architects, engineers and quantity surveyors. The spearman rank order was calculated and used to test the hypothesis that there is no significant difference between the perceptions of the different group of professionals. The results showed that there is an agreement in the ranking with a strong relationship among the professionals. Ability of the client to choose the right design team is the most important factor in delivering quality service. Other important factors are staff motivation and training, commitment of members of staff of the design team, long term potential relationship with client organization, adequate authority for the design team to perform effectively and the client’s financial position. The result will guide both client and practitioners about those factors that need to be focused to improve service delivery
PERSONALISATION OF INTERNET BASED BUSINESS OFFICE LAYOUT
Full text linkIn current era, the nature of business is ever-changing where communication and interaction between office workers are encouraged as the scope of work for office is expanding. Traditional offices with identical cubicles separated with panels are ineffective because not all workers are in the same activity mode at the same time. Providing and maintaining a comfortable and healthy office environment is vital consideration in designing an office. The interior layout design parameter involved are the comfortability of furniture, surrounding temperature, amount of lighting provided, the quality of indoor air, spatial arrangement, the condition of environment in terms of noise and privacy, and finally the 2D horizontal and vertical layout. This research seeks to identify the factors of interior layout design parameter that will affect the productivity and performance of the workers. The research is conducted using quantitative method. Questionnaire is distributed to the building occupants to evaluate and obtain their opinion on the satisfaction level of the layout at their workplace. The user satisfaction and perception on the existing interior layout design are gathered by using a questionnaire survey. The study proves that the workers are most satisfied with the lighting and least satisfied with the furniture at their existing interior layout design. The workers from both case studies agreed that the interior layout design parameter that has the most effect on the productivity is the environment noise and privacy; while 2D horizontal and vertical layout has the least effect
SUSTAINABILITY ASSESSMENT IN CONSTRUCTION ORGANISATIONS’ PROJECT DELIVERY PRACTICE IN NIGERIA
Full text linkBased on the growing ethos that construction organisations can benefit from implementing sustainable practices, this study evaluated main contractors’ project delivery practices for sustainability. The objectives were to validate set of empirically weighted criteria for construction organisations’ sustainability practice assessment. The weighted criteria were validated by assessing three main contractors’ organisations’ sustainability performance in four projects. The sustainability performance was evaluated based on sound environmental management principles, robust stakeholder engagement and responsible project management. Data were collected using questionnaire survey and project auditing. The study targeted 76 stakeholders in contractors and engineering consultancy organisations in Akwa Ibom State, Nigeria. Criterion suitability was based on respondents’ agreement score in inter-rater agreement (IRA) scale. Correlational effects were explored in published and assessed weightings using Multiple Analysis of Variance (MANOVA). The finding indicated contractors’ inclination towards sustainable construction practice must be strengthened. MANOVA correlation showed published and assessed weightings differ significantly with (Lambda (4, 2) = 0.056, p = 0.418). The study submits weighted criteria are suitable for assessing a practice. The criteria are by this means validated and form assessment benchmarks for use in the absence of standard tool. The region must institute incentive and reward systems to stimulate widespread sustainable practices application within the contracting sector
ASSESSMENT OF ENERGY CONSUMPTION AS A PERFORMANCE INDEX IN HIGH-RISE BUILDINGS IN HANOI, VIETNAM
Full text linkThis research aims to at investigating the actual performance of high-rise office buildings in terms of the indoor environment and energy consumption. Data collection was based on the onsite measurement of five buildings in operation in Hanoi, Vietnam. The thermal environment, illuminance, CO2 concentration, and energy consumption were the basic parameters analyzed as a fundamental step toward realizing and determining energy-efficient buildings. The current situation can be roughly was described; the most of methodology follow the western standard and there still be less data that show the actual situation under building operation documented. To analyze and evaluate, this research conducted measurement of indoor environment quality (IEQ) and energy consumption of high-rise office buildings between 2014 and 2015 in Hanoi. From the result, it is presented evident that the overall energy consumption and indoor environment of office buildings in Vietnam are not in a negative situation to compare favorably with international standards. However, it is also presented that there is a large high fluctuation in the thermal environment. The electricity consumption has strong relationship with outdoor temperature obviously and the peak consumption is observed in the summer. The consumption doesn’t increase in winter despite indoor temperature show being lower than the standard comfort criteria-zone. This results in the lower energy consumption in the observed buildings due to the unique climate of Hanoi and inappropriate building operation mainly because of such as the insufficient operation of air conditioning systems and the air-tightness of building envelopes

The results conclude that there were significance relationships between the groups of variables in the conceptual framework, thus, contribute in managing uncertainties factors of building refurbishment projects through leadership qualities among project managers and for furthered research in this area
ASSESSMENT OF CRIME PREVENTION MECHANISMS IN PUBLIC BUILDINGS IN AKWA IBOM STATE OF NIGERIA
Full text linkThe occurrence of crime is very rampant in the Nigerian society and its multi-dimensional nature is a threat to both national and individual security, safety and development. This paper argued that the environment and building could be designed to deter, delay, detect and deny access to unauthorised users thereby preventing crime. The research methodology adopted for the study was survey research method. Purposive sampling was used. Observation of facilities in legislative and judiciary complexes was undertaken. The findings revealed that only basic crime prevention mechanisms were applied. Critical and important anti-terrorism and high profile crime prevention mechanisms such as protective glazing, vehicle access control systems and barriers among others were not applied leaving the facilities vulnerable to criminal actions involving use of light arms. The test of hypotheses using chi-square with significance at 0.05 revealed that the application of the mechanisms depended on the type of facility. The study concluded that the public buildings and the users in the study area were not adequately secured against high profile criminal actions. It recommended appropriate upgrading of the existing facilities and use of relevant crime prevention mechanisms that can impact on terrorism and general crime prevention through proper collaboration among professional stakeholders
A FRAMEWORK FOR SUSTAINABLE ARCHITECTURE IN IRAN WITH EMPHASIS ON THE VIEWS OF SCHOLARS
Full text linkDevelopment of the built environment needs to be addressed in a way that is socially and ecologically responsible. There is great urgency to make sustainable interventions in Iran, while built environments are being created without the above engagement. Lack of awareness and consensus on sustainable actions needs formulation of a framework set by scholars analyzing effects of its components in a comprehensive model. The need to develop an instrument for investigation of views of scholars has instigated the researcher to collect the necessary data through interviews and prepare a research questionnaire. Moreover, the exploratory factor analysis survey method was employed, so that structural equation can be used for modeling purposes. The results led to development of a theoretical model to describe views of sustainable architecture in Iran. Results show that environmental and productivity in the use of nature aspects of buildings is the cause of transition to sustainable architecture. Technology, construction and operations of buildings aspects as mediating variables have effects on environmental awareness as dependent variable of transition to sustainable architecture in Iran. The results can pave the path for further research in this area and orient the research priorities for sustainable architecture in Iran

INVESTIGATING THE AESTHETIC IMPACT OF TALL BUILDINGS ON URBAN LANDSCAPE
Full text linkIn this paper, we tried to investigate the aesthetic role of tall buildings in urban landscape to provide a better understanding of future tall buildings. In this study first we explained aesthetics in urban landscape; since our focus was on scenic beauty, we reviewed some techniques for evaluating visual aesthetics. In the second part, we discussed aesthetics of tall buildings in urban landscape. Finally we derived the most important factors in aesthetic impacts of tomorrow’s tall buildings. In reviewing tall buildings, it was found that the top is the most important component of the tall building in terms of its impression in the city silhouette. We also found out that factors, such as “the degree of silhouette complexity”, “shape”, “number of view corridors”, “the height of tall building against the natural backdrops”, and “skyline” are important factors in the aesthetics of tall buildings in the city context
