Abstract Construction surveying consist in overall surveying works performed at every stage of the construction and use of a building structure. The surveyor participates in the processes of designing, direct implementation, maintenance and use, as well as demolition of a building structure. Advanced surveying techniques, such as laser scanning and UAV photogrammetry, are being increasingly used to perform the surveyor’s tasks. The aim of this research paper was to analyze the Polish legal regulations for the possibilities of applying the above-mentioned techniques to carry out the surveying works which are subject to the obligatory submission to public administration authorities. The primary focus was placed on the type of the works associated with construction surveying. The conducted research studies confirmed the lack of appropriate guidelines that would clearly define the scope and method of using laser scanning and UAV photogrammetry in construction surveying. At the same time, it was demonstrated that both these techniques of spatial data acquisition were sufficiently accurate to perform plane and vertical land surveys pursuant to the legal acts currently in force in Poland, and they can be used at selected stages of construction surveying. Finally, the authors proposed some solutions that would make it easier for the surveyors to use laser scanning and UAV photogrammetry in standard surveying works.

Promoting and managing sustainable territorial development require adequate tools that enable territorial managers to formulate appropriate choices. Technological solutions have emerged, and the paradigm has shifted from isolated GIS to a more collaborative production and dissemination of geographic data using spatial data infrastructures (SDI). A critical dataset for municipal land administration is cadastre. ISO 19152 standard of the Land Administration Domain Model (LADM) was published in 2012. Also, technology evolution, namely unmanned aerial vehicles (UAV), has changed data acquisition for cadastre. These are three pillars of modern territorial management: openness, co-production, and data sharing (SDI); models (LADM); affordable technology (UAV). This chapter presents how municipalities can develop an SDI project, incorporating LADM guidelines and UAV data acquisition. The case study is based on a group of 32 small municipalities from São Paulo state, in Brazil, known as UNIPONTAL.

A project started last year called MORE-CONNECT, which focuses on the renovation of buildings (especially building facades) using prefabricated elements. The aim of this project is to create a competitive solution consisting of a technology and processes which enable fast, cost-effective renovation with minimal difficulties to inhabitants. Significant cost savings in renovation costs lies in the usage of prefabricated elements and the reduction of construction works on site. The precision of the prefabricated element depends on the precision of the construction, project and building documentation. This article offers an overview of the possible methods for building documentation and spatial data transfer into BIM (Building Information Modelling) software. The description of methods focuses on laser scanning and photogrammetry (including RPAS based), its advantages, disadvantages and limitations according to the documented building, level of renovation, situation on site etc. The next part involves spatial data transfer into BIM software. A proposed solution is tested in a case study.

Unmanned aerial vehicles, equipped with various sensors and devices, are increasingly used to acquire geospatial data in geodesy, geoinformatics, and environmental studies. In this context, a new research and professional field has been developed – UAV photogrammetry – dealing with photogrammetry data acquisition and data processing, acquired by unmanned aerial vehicles. In this study, we analyse the selected factors that impact the quality of data provided using UAV photogrammetry, with the focus on positional accuracy; they are discussed in three groups: (a) factors related to the camera properties and the quality of images; (b) factors related to the mission planning and execution; and (c) factors related to the indirect georeferencing of images using ground control points. These selected factors are analysed based on the detailed review of relevant scientific publications. Additionally, the influence of the number of ground control points and their spatial distribution on point clouds' positional accuracy has been investigated for the case study. As the conclusion, key findings and recommendations for UAV photogrammetric projects are given; we have highlighted the importance of suitable lighting and weather conditions when performing UAV missions for spatial data acquisition, quality equipment, appropriate parameters of UAV data acquisition, and a sufficient number of ground control points, which should be determined with the appropriate positional accuracy and their correct distribution in the field.

Unternehmen des produzierenden Gewerbes sind mit einem zunehmend dynamischen Marktumfeld konfrontiert, weshalb fabrikplanerische Anpassungen immer schneller erfolgen müssen. Der größte Zeitanteil in Fabrikplanungsprojekten wird jedoch für die Datensuche, -aufbereitung und den anschließenden Informationsaustausch zwischen den unterschiedlichen Beteiligten aufgewendet. Um diesen Aufwand zu reduzieren, wird ein Konzept zur kollaborativen Fabrikplanung mit Building Information Modeling vorgestellt.   The production industry is facing increasingly dynamic market conditions. Therefore, the adaption of production systems must happen ever more quickly. However, data acquisition, processing and the subsequent exchange of information takes up a lot of time in factory planning projects. To reduce this effort, the paper introduces a method for collaborative factory planning based on building information modelling.

Purpose This paper aims to develop a framework for optimising building performance through the integration between risk management (RM) and building information modelling (BIM) during the design process. Design/methodology/approach To achieve this aim, a research strategy consisting of literature review, case studies and survey questionnaire is designed to accomplish four objectives. First, to examine the concepts of design process, building performance, RM and BIM; second, to present three case studies to explain the role of using RM and BIM capabilities towards optimising building performance; third, to investigate the perception and application of architectural design firms in Egypt towards the role of RM and BIM for enhancing building performance during the design process; and finally, to develop a framework integrating RM and BIM during the design process as an approach for optimising building performance. Findings Through literature review, the research identified 18 risks that hamper optimising building performance during the design process. In addition, 11 building performance values and 20 BIM technologies were defined. Results of data analysis showed that “Design budget overrun”, “Lack of considering life cycle cost” and “Inefficient use of the design time” were ranked the highest risks that affect the optimisation of building performance. Respondents ranked “Risk avoid” or “Risk transfer” as the most risk responses adopted in the Egyptian context. In addition, “BIM As Built” was ranked the highest BIM technology used for overcoming risks during the design process. These findings necessitated taking action towards developing a framework to optimising building performance. Originality/value The research identified the risks that affect optimising building performance during the design process. It focuses on improving the design process through using the capabilities of BIM technologies towards overcoming these risks during the design process. The proposed framework which integrates RM and BIM represents a synthesis that is novel and creative in thought and adds value to the knowledge in a manner that has not previously occurred.
