Study Results

The oil price has fallen significantly from its peak at $128.14 per barrel in March 2012, reaching a low of $29 in February 2016. Kuwait depends mainly on oil revenue to finance infrastructure governmental projects. Oil price decline has a direct impact on economic and capital expenditure in the construction industry’s resources in Kuwait, specifically construction material. This research investigates the effect of changes in oil prices over range from 2007-2017 on the construction industry in Kuwait. Different types of data regarding global economic data, construction materials, and awarded contracts during the study period were gathered and analyzed. A set of statistical and correlation analysis are performed. The study revealed that many construction materials are affected by oil price in Kuwait. The GDP is highly affected by oil price drop; this implies that there is a limited result of government plans to divers governmental finance. A regression model is proposed to forecast the construction cost per square meter in Kuwaiti dinar based on study variables. The study results can be used to evaluate the effect of oil price drop in similar construction environments such as Gulf countries and to predict construction costs changes due to oil price decline.

The Impact

This work is set out as an investigation into the impact of change in oil prices on government revenue broken into oil and nonoil component. Drawing data from the Central Bank Statistical Bulletin and covering the period 1981 to 2018. The Autoregressive Distributed Lag (ARDL) Model was used because of its advantages over other regression techniques. It was found that changes in oil price affected oil revenue within the studied period leaving no significant impact on nonoil revenue. The result obviously reflects the Nigerian economy and its mono-product characteristic. It is therefore recommended that a conscious policy effort should be made to diversify the economy in a manner that makes revenue to the government multifarious functions.

The Impact

Concrete has been used in the construction industry since long times. It is probably the most widely used construction material in the world, largely due to the abundance of the raw materials for cement manufacture, low relative cost and the versatility and adaptability of concrete in forming various structural shapes. Massive production of concrete and the associated substantial manufacture of cement have however been observed to have a very negative impact. One of the biggest issues of growing concern at the moment faced by concrete industries is the impact of cement production on the environment. The production of cement not only depletes significant amount of natural resources, but also liberates a considerable amount of carbon dioxide (CO2) and other greenhouse gases into the atmosphere as a result of decarbonation of limestone and the combustion of fossil fuels. In addition, cement is among the most energy intensive construction materials, after aluminium and steel [1].

Globally, the construction industry is a catalyst for economic development. This is because it is the bedrock for economic activities. Over the years, the construction industry has been criticised for under-performing which brings about a decline in productivity. In order to improve construction project performance for infrastructural delivery, there are factors to be considered, inter alia, construction material related factors, construction machinery related factors, and project management related factors. In achieving this objective, a questionnaire survey was expedited to purposive practioners to evaluate the relative importance index of these factors. The paper reveals that in the category of construction material related factors, unsuitable locations for material and late delivery of construction materials topped the list with a MS value of 4.53 and 4.15, respectively; in the category of construction machinery related factors, poor maintenance of tools and machinery and difficulties in hiring construction tools and machinery topped the list with a MS value of 4.54 and 4.50, respectively; while in the category of project management related factors, efficient time management and project quality management topped the list with a MS value of 4.83 and 4.70, respectively. In addition, performance improvement factors were also highlighted.

Purpose The purpose of this paper is to quantify the carbon emissions emitted by two different typical apartment units representative of two different construction periods in Kosovo due to main construction materials as a consequence of embodied energy. Design/methodology/approach The present study uses a three-step (bottom-up) process-based life cycle analysis of the construction material set for two different apartment units. The current study uses material analysis. Embodied CO2 is estimated by multiplying material masses with the corresponding ECO2 coefficients (kg CO2/kg). Due to the lack of a comprehensive Kosovo database, data from an international database are utilized. The results provide practical baseline indicators for the contribution of each material in terms of mass and embodied CO2. Findings Results of quantitative research find that apartment unit representative of the old communist-era construction produces 50 percent more embodied CO2 emissions than an apartment unit that is representative of modern construction in Kosovo. The study finds that this difference comes mainly because of the utilization of larger quantities of steel, concrete, and precast fabricated concrete in the apartment unit that is representative of the old communist era. Research limitations/implications The calculation of embodied CO2 emissions for major construction materials in typical apartments in Kosovo can help in the development of national databases in the future. The availability of such databases could help the construction industry in Kosovo to open up to new sustainable design approaches since such databases and evaluations performed in the national context in Kosovo could help the builders in selecting, assessing and using environmentally friendly materials during the design or refurbishment stage of a building. Originality/value This paper is the first investigation of the embodied carbon emission in two different typical apartment building structures in Kosovo.

Materials Recycling

Today, rapidly industrialization and an accompanying increase of the world population cause diminishing of the limited amount of natural resources. The purpose of this study is to examine the recycling applications in the construction industry and to investigate the contribution of scrapped tires to construction industry and national economy. The construction industry is one of the fields that has the largest raw material consumption. Due to the high demand for the construction materials recycling is often employed and provide a significant economic contribution. Today, scrapped tires both exist abundantly and are currently worthless wastes. This wastes not only pollute the environment but also cause negative effects on the human healthy. Because of this reason, old tires are either reduced to certain dimension or melted in the recycling plants. The new products that therefore emerges is added in to the hot mix asphalt and then used in highway constructions, which are a significant capital expenditure for the national economy. As a result of this study, it is reveal that recycling in the construction industry has very significant positive contribution to natural environment and the existing recycling resources are not well-utilized. Moreover, the applications that have been done so far provided significant contributions to the national economy. Consequently, recycling studies should be speeded up and governmental supports should be put into practice.

The Impact

The paper examines the impact of oil price shocks on inflation, as well as the impact of the choice of the monetary policy regime on the strength of this influence. We used dynamic models on panel data for the countries of the world for the period from 2000 to 2017. It is shown that mainly the impact of changes in oil prices on inflation is carried out through the channel of exchange rate. The paper demonstrates the influence of the transition to inflation targeting on the nature of the relationship between oil price shocks and inflation. This effect is asymmetrical: during periods of rising oil prices, inflation targeting reduces the effect of the transfer of oil prices, limiting negative effects of shock. During periods of decline in oil prices, this monetary policy regime, in contrast, contributes to a stronger transfer, helping to reduce inflation.

Study Results

The clamour for better quality graduates by architects in the Nigerian Construction Industry (NCI) necessitates a look into the core competencies and the adequacy of architecture education in preparing architecture graduates for professional practice. 116 self-report likertscale questionnaires from architecture graduates (2009-2015), academics and employers were analysed to establish core competencies developed by the graduates while in school. Descriptive statistics, t-tests as well as Mann-Whitney tests for differences in ratings were employed for the study. Results reveal the perceived adequacy of architecture education for the future career of graduates from the academic perspective. Graduates were most proficient at design related competencies while AutoCAD was still considered the most important CAD competency for architecture graduates in the NCI. The study recommends more frequent evaluations of competencies for employability in collaboration with industry as well as embracing BIM related software in line with global best practices.

The Impact

This study analyses the impact of exchange rate and oil prices on the yield of sovereign bond and sukuk for Malaysian capital market. This study aims to ascertain the effect of weakening Malaysian Ringgit and declining of crude oil price on the fixed income investors in the emerging capital market. This study utilises daily time series data of Malaysian exchange rate, oil price and the yield of Malaysian sovereign bond and sukuk from year 2006 until 2015. The findings show that the weakening of exchange rate and oil prices contribute different impacts in the short and long run. In the short run, the exchange rate and oil prices does not have a direct relation with the yield of sovereign bond and sukuk. However, in the long run, the result reveals that there is a significant relationship between exchange rate and oil prices on the yield of sovereign bond and sukuk. It is evident that only a unidirectional causality relation is present between exchange rate and oil price towards selected yield of Malaysian sovereign bond and sukuk. This study provides numerical and empirical insights on issues relating to capital market that supports public authorities and private institutions on their decision and policymaking process.

The objective of this study was to determine the requirements for steels used as construction materials for chemical apparatus operating at an elevated temperature and to correlate them with the properties of the tested steels. The experimental part examined the influence of the annealing process on the structure and properties of X2CrNiMoN22-5-3 (1.4462) and X2CrNiMoCuWN25-7-4 (1.4501) steel. Heat treatment was carried out on the tested samples at a temperature of 600 °C and 800 °C. Changes were observed after the indicated time intervals of 250 and 500 h. In order to determine the differences between the initial state and after individual annealing stages, metallographic specimens were performed, the structure was analyzed using an optical microscope and the micro-hardness was measured using the Vickers method. Potentiostatic tests of the samples were carried out to assess the influence of thermal process parameters on the electrochemical properties of the passive layer. An increase in the hardness of the samples was observed with increasing temperature and annealing time, the disappearance of magnetic properties for both samples after annealing at the temperature of 800 °C, as well as a significant deterioration in corrosion resistance in the case of treatment at a higher temperature.

Bounds Test

This paper analyses the links established between environmental indices and the oil price adopting a double perspective, long-term and short-term relationships. For that purpose, we employ the Bounds Test and bivariate conditional heteroscedasticity models. In the long run, the pattern of behaviour of environmental indices clearly differed from that of the oil prices, and it was not possible to identify cointegrating vectors. In the short-term, it was possible to conclude that, in contemporaneous terms, the variables studied tended to follow similar paths. When the lag of the oil price variable was considered, the impacts produced on the stock market sectors were partially of a negative nature, which allows us to suppose that this variable plays the role of a risk factor for environmental investment.
