The paper presents the problem of building disturbances, which are usually an inseparable element during the implementation of construction projects. They were classified, their causes and sides of the construction process responsible for their creation were identified on the basis of the analyzed construction investment. In addition, using the Earned Value Management method, the scale of delays arising in construction works and the related effects were determined. The important role of close cooperation and good communication between all participants of the construction process was emphasized, which would reduce the phenomenon of building disturbances, but also mitigate the negative effects of delays that have already occurred.
Ninety-eight per cent of world ship breaking (ship demolition) today is carried out in India, Bangladesh, China, Pakistan and Turkey.
The 1989 Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal as well as Dutch, French, Turkish, Indian and British case-law consider decommissioned ships as waste. Due to limited effectiveness of the Basel Convention a new one has been adopted — the 2009 Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships. The Hong Kong Convention will enter into force when three conditions set out in its Article 17 are met; it means at least one leading ship breaking country must ratify it.
The European Union is a leading proponent of signature of the Hong Kong Convention. Its ratification by the EU shall be a significant quantitative and political stimulus towards its entry into force. In order to encourage the ratification processes by EU member states, the European Parliament and the Council have adopted Regulation (EU) No 1257/2013 of 20 November 2013 on ship recycling.
