Introduction (and purpose) – Since the 1970s, digital development and modeling has improved from simple digital illustrations of a building to advanced software, such as Building Information Modelling (BIM), that allows contractors to easily collaborate on a shared model. These advanced modelling systems create the opportunity to optimize planning as well as produce a higher quality product by modelling how all the various parts of a build work together and decreasing the number of potential errors that occur on-site. To better understand how BIM can improve production, this study aims to investigate the current use of BIM and potential areas of opportunity within the prefabricated housing construction sector. Method – Data was collected through semi-structured interviews with five employees of five separate companies active in the Swedish production industry of single-family houses. Additional data was collected through a survey that was shared with a total of 17 companies, three of which partook in the survey and shared it with the companies’ employees. Results – The interviews and surveys revealed limited use of BIM technology in current developmental practice, although the company representatives still expressed interest in future technological advancement. The company representatives endorsed the ability to automate work processes in both the planning phase as well as the production phase as the greatest reason for expanding future usage. The survey revealed interest in using BIM technology to provide the opportunity to reduce the number of mistakes that occur between different contractors, where collisions may occur between unique models that have not been integrated by a single system. Analysis – According to the interview respondents, the use of BIM technology could create opportunities for businesses to remain relevant by more easily integrating future technological developments. In addition, the use of BIM technology can attract new, competent personnel. The possibility of using cloud-based BIM allows a greater degree of customer involvement in projects. However, the economic value of BIM implementation is not clear as changing established work processes may require new procedures in the company. Therefore, changing to a BIM-based work system may not be economically advantageous to companies that already have a working business model. Discussion – While indicating an interest in future development using BIM, this study revealed currently limited use of BIM technology in prefabricated housing companies, where companies currently dedicate various amounts of recourses for its technological development. A larger, randomized sample would allow for a more generalizable idea of BIM use, as this study’s results could be biased by including opinions only of those who chose to respond from a limited number of companies. The volunteer method of data collection may have skewed results, as people who choose to respond often have strong opinions about the topic. However, using a mixture of interviews and surveys did allow collection of both qualitative and quantitative data and provided an initial look into current opinions about BIM as well as areas where participants believed it could help in production, even if it is not currently in use. / Introduktion (och syfte) – Sedan 1970-talet har utvecklingen av digitala verktyg gått från enkla illustrationer, till Byggnadsinformationsmodellering (BIM), en avancerad samarbetsteknologi som tillåter olika yrkesgrupper att arbeta i en gemensam modell. Tekniken möjliggör både optimeringsmöjligheter vid planering och höjd produktionskvalitet där modelleringen av en byggnad kan minska andelen kollisioner som riskerar uppstå vid montage. För att bättre förstå hur BIM kan förbättra produktion fokuserade studien på att utvärdera nuvarande och framtida potentiella användningsområden inom den prefabricerade småhussektorn. Metod – Datainsamlingen bestod av fem semistrukturerade intervjuer från fem enskilda företag inom den svenska småhusbranschen. Intervjuerna kompletterades med en enkät som delades med totalt 17 företag, varav tre företags medarbetare delade enkäten internt inom företaget. Resultat – Både intervjuerna och enkäten visade ett begränsat användande av BIMteknik i företagens arbetsmetoder, trots det uppgav företagsrepresentanterna ett intresse i framtida teknikutveckling. Företagsrepresentanterna förespråkade möjligheterna att automatisera både projektering och produktion som drivande orsaker för fortsatt teknisk utveckling. Enkätundersökningen visade ett intresse att, i deras arbete använda BIMteknik för ökad kommunikation mellan yrkesgrupper, där potentiella kollisioner mellan modeller från olika system kan hanteras på ett effektivare sätt. Analys – Användandet av BIM-teknik kunde öka företagens möjlighet att lättare implementera framtida teknisk utveckling. Samtidigt som ett högt teknikanvändande kan attrahera ny kompetent personal. Möjligheten att förlägga BIM-tekniken till webbtjänster tillåter beställare att bli mer involverade i sitt husprojekt. Trots det är det inte klart vilket ekonomiskt värde BIM-användandet ger, där implementeringen av ett nytt system kan kräva att justering av flera redan befintliga system inom företaget. Implementeringen av ett BIM-baserat arbetssystem är därför inte en självklar investering för företag som redan i dag har en fungerande verksamhet. Diskussion – Trots ett, i dagsläget, begränsat användande av BIM-teknik visade företagen i den prefabricerande småhusindustrin ett intresse i teknikens framtida utveckling, där företag dedicerar varierande mängd resurser för teknikens utveckling. Fortsatta studier föreslås genomföra med mer omfattande, och slumpmässiga datainsamlingar eftersom undersökningen, som använt ett begränsat antal företag, har krävt att respondenten har velat delta i studien och kan med det tros kunnat gett en partisk bild om ämnet. Användandet av intervjuer för kvalitativa data och enkät för kvantitativa data tillät för en bredare spektrum av åsikter att bli hörda rörande det aktuella användandet av BIM-teknik, och inom

The aim of the thesis is the process of building technological project LIWA manufacturing facility in Pelhřimov. It deals mainly a technological process for the realization of the main building. The thesis contains a technical report, technological specification, control and test plan. Other parts of the work are time and financial plan, machine and mechanic design, project about equipment of construction site and time schedule. The annexes are further addressed drawings of the building site equipment.

This thesis deals with the construction process of the apartment house Ponavia Park located in Brno. The thesis solves the individual realization phases of the main building phase. Building site equipment is designed for the projected construction process in three different variations. A technical report is also included in the building site. Critical points within the transport of materials and machines are also verified. A financial plan for the whole building is made as an summarizing time schedule for the apartment building. The sources for the financial plan are the figures taken from the Czech building objects classifications (JKSO). The summarizing time schedule is made in MS Projekt software and it’s designed as a Gantt diagram. A design of the main building machines and mechanisms was also made for the projected construction process. All of the machines were assessed for their respective required function on the building site. Also included in this thesis is a construction method for the reinforced concrete structures. The construction method deals with the realization process of waterproof concrete, reinforcement binding, formwork of the vertical and horizontal structures and also the process of concrete curing. The construction method is followed up by quality control and test plans for reinforced concrete structures, and a construction site safety plan that is made in the form of predicted main safety risks at the building site. For the noise load on the surrounding buildings a noise study is made. The study examines the intensity of noise in the protected outdoor space. This study was made in the Hluk+ software. The thesis also includes an item budget for the apartment house that was made in Build Power S software.
