Volatility in the fluctuation of prices of building materials has made price forecast on the cost of the materials less reliable in building project management in Nigeria. In the light of this, the study examines the causes of the constant increase in the prices, as well as the implication of the price fluctuation on building projects in the study area. Survey research designs used to gather information for the study are non-parametric in nature. Data were analyzed using chi-square and likert scale to rank the various factors involved in the price fluctuation, as well as the effects of the variation on building projects respectively. Other analytical tools are price index for the rate of changes in the prices of the materials from time to time on average, and simple regression analysis for the relationship between changes in the average price of building materials and the average house rent within the last ten years. Findings reveal that inflation, force of demand and supply, and exchange rate, as economic factors among others are the most significant ones responsible for the building materials price fluctuations in the study area. Difficulty in forecast and planning, project cost overrun, as well as shortage and high cost of accommodation however, are found as the most common effects of the building materials price fluctuations. Besides, the mean un-weighted aggregate price index, and the mean house rent index for each of the successful year are discovered to be 11.02% and 8.73% respectively. Increase in the aggregate price of the building materials however caused approximately a proportional increase in the house rent, especially in the early part of the period. The variables therefore have a positive and linear relationship with the regression model of Y=5776+0.98xi, as derived from Equ.6. It is therefore recommended that research, development and improvement on local material resources be encouraged by the government and the construction stakeholders with legislative instruments against the importation of the basic building materials in Nigeria. Nevertheless, an appropriate framework designed with the aggregate building materials price indices, the model relationship between the effect of change in the aggregate price of the building materials and the consequent change in the residential house rent should be adopted in the management of building projects; for effective forecast and planning of the projects towards sustainable delivery in the study area.

The United States Environmental Protection Agency (EPA) has labeled as “friable” those building materials that are likely to readily release fibers. Friable materials when dry, can easily be crumbled, pulverized, or reduced to powder using hand pressure. Other asbestos containing building materials (ACBM) where the asbestos fibers are in a matrix of cement or bituminous or resinous binders are considered non-friable. However, when subjected to sanding, grinding, cutting or other forms of abrasion, these non-friable materials are to be treated as friable asbestos material. There has been a hypothesis that all raw asbestos fibers are encapsulated in solvents and binders and are not released as individual fibers if the material is cut or abraded. Examination of a number of different types of non-friable materials under the SEM show that after cutting or abrasion, tuffs or bundles of fibers are evident on the surfaces of the materials. When these tuffs or bundles are examined, they are shown to contain asbestos fibers which are free from binder material. These free fibers may be released into the air upon further cutting or abrasion.

The purpose of this paper is to analyze and research the legal mechanisms which make it possible to improve agroecology through the organization of cultivation of Jerusalem artichoke.Methodology. The methodology includes comprehensive analysis and generalization of available scientific, theoretical, practical and applied material and development of relevant conclusions and recommendations. During the research, the following methods of scientific cognition were used: dialectical, terminological, historical and legal, logical and normative, systemic and structural, functional, normative and dogmatic, generalization methods. Results. The process of analysis and research highlighted the possibilities of cultivating Jerusalem artichoke for improving agroecology, namely improving the ecological state of the atmosphere air and soil, preparing them for organic farming. The article contains examples of practical application of tubers of Jerusalem artichoke and herbage for the production of therapeutic and prophylactic products, alternative energy and highly efficient building materials. Scientific novelty. The study found that the authors summarized and systematized the levels of legal regulation in the field of using Jerusalem artichoke for improving agroecology, preparing soil for organic farming, in particular: the inter-sectoral level which covers the interaction of agricultural and environmental law in terms of cultivation and use of Jerusalem artichoke; the level of integrated environmental and legal regulation; level of individual resource (floristic) legal regulation; the level of environmental protection (anthropoprotection) legislation.Practical importance. The results of the study can be used in law-making and environmental protection activities related to issues of cultivating and using the Jerusalem artichoke as a means of improving agroecology.
