"Our world is changing faster than ever before. Urban areas all over the world have been developed rapidly. Unfortunately construction sector has been rejecting most of the technological opportunities while other industries have undergone significant changes over the last years due to some process and product innovations. The sector has still an intractable productivity problem. However, construction is the world's largest industry in terms of resource (including energy) usage and waste generation. Improving whole-life cycle resource efficiency and environmental impacts are considered the main challenges of the construction industry in the European Union. Such improvement can be reached thanks to digitalization, advancement of computational tools, brand new construction techniques and methods as well as innovative technologies. Incidentally, companies can boost productivity as well. To make cost performance more efficient, planners/designers should explore more construction/design alternatives and - as a result - make more accurate decisions. High complexity of the construction projects reduces a simplicity of setting up a reliable construction model ready to multi-objective optimisation. Building Information Modelling (BIM) is considered as the innovation that allows for the consistent management of information in the construction projects. This tool turns out to be useful in managing the process of building construction in the whole-life cycle perspective. Additionally, people, standards, processes and the technology form the integral parts of BIM. It is inevitable that construction companies would customise BIM gradually and have to refine and attune the method with increasing know-how."

Like in other EU countries, in Poland can be observed many ecological activities that play an important role in a balanced development of the society. Bicycle-sharing systems get more and more popular. In urban areas, tramway lines are being constructed. Local governments promote healthier and faster means of public transport. However, there are many problems waiting to be solved. This article describes a complexity of problems related to the sustainable development in urban areas. This kind of activity is represented by many different undertakings (projects) aiming for an improvement of human life while remembering about future generations. Like any project, eco-urban-projects have several important aspects that need to be considered (managed). Among them there are a cost, a scope and a schedule of the project. A quality seems very important too. Apart from the constraints represented by the Iron Triangle1, eco-urban-project planners and managers should remember about its uniqueness based on a significant impact on the environment. None undertaking is successful if it is not consulted with all stakeholders, especially those who are engaged in a dialogue on better development based on sustainability (e.g. civil society or public authorities). In the article, some examples of best practice for sustainable development in city areas were presented. A risk of ecourban-projects was discussed. ; Jarosław Górecki
