“…environmental specialists have considered the sustainability of environmental evaluation from the point of view of environmental impact assessment putting the emphasis on the fact that the living environment is a complex multi-level system, which needs to be assessed as an integrated aggregate in the context of a wide-ranging model (Bożejko et al 2012).…”

The main aim of this study was to characterize heavy metal compounds of sweep sand particles in the city of Vilnius (lithuania). These research results provide new insight into the distribution and variation of heavy metal compounds in sweep sand in the studied area. The results of this investigation reflect the level of heavy metal pollution during the winter season, thus can be used to judge the quality of storm water flowing from streets. The major heavy metals found to have accumulated were lead, nickel, zinc and copper. These research results are useful for conducting preliminary evaluations of possible heavy metal pollution in other similar cities within the european union. The general anthropogenic factor of three main types of land-use has the greatest influence on contamination of urban topsoil. in industrial sites, concentrations of key contaminants (Pb, Cu, Mn, ni) are significantly higher than in residential and public-residential areas. The present article discussed the significance of systematic sustainable evaluation as one of the most important activities associated with a sustainable approach. Consequently, to reduce a negative effect of salts on street environment, measures of environmentally sustainable development have to be undertaken.Keywords: heavy metals, deicing salts, sweep sand, sustainable development, valuation of environmental effects, environment and development.Reference to this paper should be made as follows: Kazlauskienė, A.; Valentukevičienė, M.; ignatavičius, G. 2013. sustainability assessment of heavy metals and road maintenance salts in sweep sand from roadside environment,

To cite this article: Michał Podolski (2016): Management of resources in multiunit construction projects with the use of a tabu search algorithm, Journal of Civil Engineering and Management, Abstract. The paper presents the problem of optimal management of the resources in multiunit construction project. During the creation of the models of this kind of the project the flow-shop system is rarely used. Flow-shop system now is widely applied in modelling of industrial processes, computer systems. In the model presented in the paper flow shop system with teams of working groups is used. It allows its users to shorten the time of realization of multiunit construction projects in a significant way, because works in the project can be realized by teams of working groups of any cardinality. This is new model of multiunit construction project which has not been examined in field of scheduling of construction project yet. The presented optimization model of multiunit construction project with teams of working groups performing one type of work is NP-hard optimization problem. During the scheduling of such projects there was an artificial intelligence tool used, i.e. metaheuristic tabu search algorithm. Tabu search algorithm can provide solutions of very good quality. The paper also presents a calculation example of the above mentioned problem. The obtained in calculation example result is fully satisfactory.

“…In this case, the contemporary achievements of the job scheduling theory in the field of flow shop problems will be helpful (Gupta & Stafford, 2006), which are NP-hard already for n = 3 objects of the project. These problems are mainly used in electronics, the chemical industry, the automotive industry, and less frequently in construction (Bożejko, Hejducki, & Wodecki, 2012;Bożejko, Hejducki, Uchroński, & Wodecki, 2014;Podolski, 2016Podolski, , 2017. The article (Bożejko et al, 2012) presents the problem of a multiunit construction projects, in which a solution was sought to minimize costs, including only penalties for exceeding the imposed deadlines for the construction of units.…”

The article presents the cost optimization model for multiunit construction projects. Multiunit projects constitute a special case of repetitive projects. They consist in the realization of many different, when it comes to size, types of residential, commercial, industrial buildings or engineering structures. Due to the specific character of construction works, actual schedules of such projects should not only take into account real costs of construction, but also be subject to specific restrictions, e.g. deadlines for the completion of units imposed by the investor. To solve the NP-hard problem of choosing the order of units’ construction there was metaheuristic algorithm of simulated annealing used. The objective function in the presented optimization model was the total value of the project cost determined on the basis of the mathematical programming model, taking into account direct and indirect costs, costs of missing deadlines and costs of work group discontinuities. In the article, an experimental analysis of the proposed method of solving the optimization task was carried out in a model that showed high efficiency in obtaining suboptimal solutions. In addition, the operation of the proposed model has been presented on a calculation example. The results obtained in it are fully satisfying.
