Abstract Amendment to the Act on special rules of preparation and implementation of investment in public roads resulted in an accelerated mode of acquisition of land for the development of roads. The decision to authorize the execution of road investment issued on its basis has several effects, i.e. determines the location of a road, approves surveying division, approves construction design and also results in acquisition of a real property by virtue of law by the State Treasury or local government unit, among others. The conducted study revealed that over 3 years, in this mode, the city of Krakow has acquired 31 hectares of land intended for the implementation of road investments. Compensation is determined in separate proceedings based on an appraisal study estimating property value, often at a distant time after the loss of land by the owner. One reason for the lengthy compensation proceedings is challenging the proposed amount of compensation, unregulated legal status of the property as well as imprecise legislation. It is important to properly develop geodetic and legal documentation which accompanies the application for issuance of the decision and is also used in compensation proceedings.

Development Prospects

The presented study aims to examine the current state and development prospects of self-regulation in the Russian construction industry.Aim. The study aims to conduct a comprehensive analysis of the current state and development prospects of self-regulation as an institution of public administration, identify the problems of self-regulation in the construction industry, and formulate proposals on solving the identified problems.Tasks. The authors complete the following tasks to achieve the set aim: examine the regulatory framework of the activities of self-regulatory organizations in the construction industry — construction, design, and engineering surveying; analyze the current state and positive trends of self-regulation in the field of construction; identify problems in the activities of self-regulatory organizations in the construction industry — construction, design, and engineering surveying — and development prospects of the examined alternative to government regulation.Methods. The methodological basis of the study comprises the fundamental provisions of the modern economic theory, theories of public and municipal administration and legal sciences. The information base includes regulatory and legal acts of the Russian Federation on self-regulation in the construction industry, data from the State Register of Self-Regulatory Organizations, and statistics in the field of construction.Results. At the current stage of development of self-regulation in the construction industry, the most efficient mechanism for this institution involves guaranteed compensation for damage caused due to shortcomings in the works and services during construction, renovation, capital repairs of construction objects, engineering surveying, design. The victims should be compensated not out of insurance payments under civil insurance contracts, but rather out of the compensation funds of self-regulatory organizations.Conclusion. This study makes it possible to assess the institution of self-regulation in the construction industry — construction, design, and engineering surveying — as an efficient institution for proper protection of the interests of consumers of construction works and services and those of the government.

Abstract Background Mechanical chest compression (mCPR) offers advantages during transport under cardiopulmonary resuscitation. Little is known how devices of different design perform en-route. Aim of the study was to measure performance of mCPR devices of different construction-design during ground-based pre-hospital transport. Methods We tested animax mono (AM), autopulse (AP), corpuls cpr (CC) and LUCAS2 (L2). The route had 6 stages (transport on soft stretcher or gurney involving a stairwell, trips with turntable ladder, rescue basket and ambulance including loading/unloading). Stationary mCPR with the respective device served as control. A four-person team carried an intubated and bag-ventilated mannequin under mCPR to assess device-stability (displacement, pressure point correctness), compliance with 2015 ERC guideline criteria for high-quality chest compressions (frequency, proportion of recommended pressure depth and compression-ventilation ratio) and user satisfaction (by standardized questionnaire). Results All devices performed comparable to stationary use. Displacement rates ranged from 83% (AM) to 11% (L2). Two incorrect pressure points occurred over 15,962 compressions (0.013%). Guideline-compliant pressure depth was > 90% in all devices. Electrically powered devices showed constant frequencies while muscle-powered AM showed more variability (median 100/min, interquartile range 9). Although physical effort of AM use was comparable (median 4.0 vs. 4.5 on visual scale up to 10), participants preferred electrical devices. Conclusion All devices showed good to very good performance although device-stability, guideline compliance and user satisfaction varied by design. Our results underline the importance to check stability and connection to patient under transport.

Key stakeholders in industry are highly responsible for achieving energy performance targets. Particularly, this paper assesses the attitudes, approaches, and experiences of Finnish construction professionals regarding energy-efficient buildings, or nZEBs. A three-tier investigation was conducted including surveys and expert interviews with several stakeholders. The structure of this approach was informed by preliminary data and information available on the Finnish construction sector. The questionnaire showed that the stakeholders ranked energy efficiency and embodied energy/carbon as very important. The survey highlighted that the importance of the embodied carbon CO2 in the materials is less important than the energy efficiency from many of the stakeholders’ points of view. “Energy efficiency” is very important for ESCOs, contractors, and facility managers followed by architects, HVAC engineers, and construction design engineers. Nevertheless, the opinions of architects ranked “embodied energy CO2” as the most important regarding nZEB. When it comes to the importance of “running time emissions” toward nZEB, contractors and ESCO companies ranked it as 1 for importance followed by property owners (78%) and tenants (75%). It is very fascinating to see from the survey that “running time carbon emissions” has been ranked 1 (very important) by all stakeholders. This study will enable construction industry stakeholders to make provisions for overcoming the barriers, gaps, and challenges identified in the practices of the nZEB projects. It will also inform the formulation of policies that drive retrofit uptake.
