Detta examensarbete, Tidplanering av ett stort byggprojekt är en fördjupning inom byggstyrning med fokus på hur planeringsarbetet kan förbättras. Rapporten baseras på Skanskas planeringsarbete av Nya Karolinska Solna. Fördjupningen bygger på kvalitativa intervjuer med personal ur utvalda projektfaser och erforderliga dokument, som ger en närmare inblick i hur arbetet med tidplanering utförs och kommuniceras. Arbetet resulterade i slutsatsen att ledningsverktyget Last planner får samtliga befattningar på byggarbetsplatsen att kommunicera bättre med varandra och uppmärksammar eventuella problem i god tid. Skanska rekommenderas därför att implementera Last planner i framtida projekt. Skanska bör avsätta mer tid för projektering innan produktionen påbörjar. Detta gör att de minskar risken för förseningar i sina projekt. Tillämpning av 4D‐odeller förenklar förståelsen för hur projektet utvecklas under arbetets gång i jämförelse med det planerade arbetet. Därför kan Skanska med fördel använda sig utav 4D-modellering inom framtida projekt. Skanska rekommenderas att ta fram arbetsmallar för 4D-modelleringen och till stöd för framställandet av 3-veckorstidplaner, där det framgår hur de använder vissa funktioner i planeringsprogrammen samt riktlinjer för hur tidplaner ska utformas. Vi rekommenderar att planerare ges möjligheten att hålla återkommande möten för erfarenhetsutbyte. Även om faserna skiljer sig åt, kan planerare använda sig av varandras erfarenheter i framtida projekt och det är ett bra sätt att bibehålla kunskapen inom Skanska. / This thesis is an in-depth study of building management focusing solely on time planning of a large-scale building project. The report is based on planning within New Karolinska Solna, a project by Skanska. The study was conducted through qualitative interviews on site as well as acquiring necessary documents in relation to the thesis subject. The material that was gathered gave insight into how the time plans are produced  and communicated. This brought about the conclusion that Last planner, a communications method, should be implemented in future Skanska projects as it is a holistic approach to communicating time plans by involving all involved in the project.  The design team should be given more time to finish all necessary drawings before construction work begins. This will result in a decrease of delays caused by lack of drawings. Applying the use of 4D-models clarifies, in a generally understandable way, the development of the construction work in comparison to what was initially planned. Therefor, the usage of such models is an advantage for use in future projects. Develop working templates for 4D-models, and as support for producing 3-week look-ahead time plans, with  clear guidelines for the layout of time plans as well as how certain functions are used within planning programs. We recommend that the planners be given the opportunity to hold regular meetings to exchange ideas and individual experience, even though phases may differ from each other. This would be a positive step in maintaining knowledge within Skanska.

In November 2016 a brand new and highly technological hospital called New Karolinska Solna opened in Stockholm. In connection with the planning of the hospital, new medical devices were procured, including a new infusion system that is now in use. Previously, each ward at the hospital had their own pumps and was responsible for updates and maintenance. Now, the hospital will instead have a floating pump system, which means that the hospital will own the pumps. The infusion pumps will be floating between the wards without being linked to a specific ward or department. The updates that were previously done when the need arose at the ward will now be a common process for the entire hospital. The aim of the project was to develop new guidelines for how the update process should be done on New Karolinska Solna's new infusion pump system. Through interviews with key personnel during the procurement process, the medical technicians department and caseworkers, new guidelines have been written, given the already existing technical conditions. During the course of the project it has been found that there are major shortcomings of information and communication within the hospital. The guidelines presented in the result are an important part to ensure that information related to the update comes to the caregivers at New Karolinska Solna, thus simplifying and streamlining the update of the infusion pumps.

The purpose of the study was to explore how property management companies view of Building Information Modeling (BIM) as a working method in property management process, and to explore the companies efforts at BIM in terms of the level of detail on BIM object implementation in property management. The study includes both companies that have and do not have contributions in BIM. The exploration was aimed at two companies and their varying ways of working to inform the needs of BIM in property management. The purpose of the study was also to give a clear picture of how BIM tools should be defined in the management process. The work was used of qualitative methods to answer the questions first consisted of a literature review, interviews and case study. The case study was about BIM implementation in New Karolinska Solna. The result showed that the definition of BIM in property management companies is not clear yet. The companies have intended to use BIM, but they are not there yet, there should be a type of requirements list that works with planning and production and benefit from using BIM in the property management. According to respondents, most of the common reasons why BIM was not used were because the approach of the tool. There is no proper structure or common working method of how the tool would be applied. Many literature sources including respondents claimed that BIM seemed good and have a good potential to be the future work process. BIM leads to improved work environment, improved sustainability development, good marketing, increased quality in work, time savings, and improved project management. As a suggestion as to how BIM could be implemented, it can be described in a few steps, which is status analysis, identify the benefits of BIM, start implementing on a smaller scale, follow up continuously, improve and expand the work and last but not least Integrate information. The conclusions that can be drawn from the results and literature study were that BIM can improve the quality management of the properties, but it is important to find a reasonable level of BIM implementation as well as a suitable detail level of BIM-model.
