    Anbud: Faktorer och förbättringsmöjligheter i anbudsprocessen2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The report shows how extensive the tender process is and what factors to consider in order tosubmit a winning bid. It highlights the different parts of the tender process and makes adeeper analysis of some of the most important factors. Bidding is not just about value whatsomething will cost. Because companies rarely are alone, they are finding ways and solutionsthat make the offer competitive. There is a high pace in the construction industry andconstruction companies currently have a lot to do.The report is written together with RO-Gruppen and a survey is the basis for the analysis. Thegoal was to describe RO-Gruppens work and to find possible improvement potential.As specifications, customers and procurement variations vary, it’s difficult to always followthe same template. Transparency and flexibility is required to analyze what exactly the clientis looking for. Experience proved to be a decisive factor, both according to the literature andthe questionnaire survey.

    En jämförande studie mellan platsgjuten betongvägg och skalvägg: Kostnad och tid för respektive byggmetod2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The thesis is a comparison between two different construction methods: half shell precast walls and site cast concrete walls. The study has been made for SEFA Betongentreprenad AB who is aiming for the most profitable construction method.The important aspects, which are emphasized in this thesis are costs, time and working environment.The result shows that a building with half shell precast walls is causing increased material cost in the project which also leads to a higher prime cost for the concrete contractor. On the contrary it will require shorter time schedule compared to working with the site concrete wall which the main contractor benefits from, because less time equals decreased overhead cost and management cost. In addition half shell precast walls provides a better working environment compared to site cat concrete walls because less work activities are required at the worksite which also leads to a reduction of accidents.Time and cost is based on unit-time from Nybyggnadslistan 1999 and the price inquiry. To compile the prime cost and time for the total work a careful calculation has been performed in various computer programs so like Bluebem, Wikells and Excel. The survey is based on documentation of a project which includes both a school and student dormitory in Lund.

    Digitalisering av byggsektorn2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The digital progress is slow within the constructional sector in comparison to other type of businesses and it has the reputation of being relatively conservative. To say that the progress is standing still would be mistake since the majority of constructional companies are working actively for a more digital construction site. Even though these companies are working hard towards a more digital sector the construction site is dominated by paper documents, non-autonomic systems and the labor is done the same way as it has been done for decades. Even though multiple digital tools and implementation models are available the construction sector is facing a lot of resistance. This report examines those digital innovations that are on the rampaging and can do a significant good within the construction sector.

    Method: Through search engines at the university's database, as well as the internet, collection of raw data was collected, which would then be analyzed and underlie for qualitative collection methods. The literature study was the foundation of the semistructured interviews, which in turn enabled a comparison between the theoretical framework and interview results.

    Findings: A vast majority of the interviewed participants believe that the 3D-printer sometime in the future may be used within the construction sector. An implementation of the 3D-printer would induce shorter production times, reduced production costs, elimination of waste and reduced costs for labor. Autonomic systems will probably not be implemented on construction sites within a short future since different construction projects are to diverse. If the construction would become more monotonic it would ease considerably, but today one project is rarely analogous to the other. Big data is an innovation that could revolutionize the construction sector in a lot of different ways. The respondents did not understand the meaning of the term, which interpret that it is not an innovation in focus for the time being. The possibilities of Big data are substantial and it could be used for more effective communication, more efficiency within the construction site, more detailed checkups of machinery and more controlled building material checkups.

    Implications: For a generally successful implementation of 3D-printers they need to be affordable for the smaller companies. Otherwise the larger firms risk to put the smaller firms out of business. Since concrete is a material with a relatively large impact on the environment this may cause consequences for the environment in the future since its already in an exposed situation. Since it´s globally working actively with improving the environment the focus should be in producing more environmentally acceptable concrete for the 31d-printers.

    Limitations: The study was limited to a handful of Swedish constructional companies within the Gothenburg region. In the report, only the opinions of a few respondent are taken to consideration.

    Fuktsäkerhet inom nyproduktion: Väderskydd2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report is created in order to pay attention to moisture safety in new constructions with the help of weather protection systems. This is a new technique which has been introduced to the construction business, but it is a technique that has still not raised enough attention in the business. It is obvious that the advantages with such a system outweigh the cons although most clients choose the traditional way of retaining a smaller budget when the production starts, a short term solution which leads to greater risks due to a lack of moisture protection during construction. It could be difficult to win procurement for an entrepreneur, with calculations included for weather protection system because of high costs. The combination of weather protected construction and prefabricated material can be used to minimize the risk of moisture damage. Prefabricated construction also contributes to shorter construction times and less workspace. Due to the difficulty in presenting concrete calculations for usage of weather protection systems, the efficiency gains are highlighted to promote knowledge about benefits. The earlier the decision of implementation of weather protection systems are made, the better the construction is secured from moisture. Many clients have been interviewed during this project and they found the high costs of such a system to be a disadvantage. The purpose of this research is to change this viewpoint and prove the long-term practical and economic advantages. Production not reliant on weather will yield favorable results for multiple parties invested in the project.

    Underentreprenörernas säkerhetsarbete genom arbetsberedningar: Riskinventering, riskbedömning och arbetsberedning2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Each year there are serious accidents on building sites in Sweden. This thesis has been carried out in cooperation with Skanska House Region Gothenburg and aims to improve the safety of subcontractors to Skanska.The aim of the work was to find appropriate methods and tools that Skanska as the main contractor can use to support their subcontractors to a better security planning.The work begins with a literature study of how the accident statistics looks at construction sites, as well as a theoretical background to the process of risk inventories, risk assessments and work preparation is handled. The approach has been to examine through interviews, questionnaires and site visits to seven selected construction sites in western Sweden on how the subcontractors manages risk inventories, risk assessments and work preparations. We have also investigated what is being done today in the procurement process to ensure that subcontractors meet their responsibilities in terms of work environment at construction sites and what can be improved.The results of the research show that there are clear differences between how the safety cultures were among the various subcontractors. One of the problems is that the entrepreneurs do not have sufficient understanding of what they have for responsibility in the work environment at construction sites. To solve this, it has been investigated to what is important to strengthen subcontractor’s involvement and commitment that gives the employees the opportunity to improve their own responsibility.

    Erfarenhetsåterföring: En framtagen metod för att främja samverkan2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The construction industry in Sweden has seen a rise in recent years. With the increase of house production, new demands are being made on the construction companies. The construction process is shortened and made more efficient with methods such as using precast elements. But with shorter production times and increased effectivity, problems can arise.  The purpose of this report is to localize reoccurring problems in the production process. We have gathered information from the company’s own carpenters through workshops to get a clear picture of the problems in today’s production.  The construction company is quality, environment and work environment certified according to the requirements of ISO 9001, ISO 1400 and OHSAS 1800. These certifications require structured improvement work. A directive for improvement work within the company exists but is not ensued sufficiently. There are no means in the improvement work that works for all roles within the company. With the gathered information we’ve developed an instrument that can increase effectivity in the production process as well as contribute to a stimulating work environment for the carpenters.  The field we chose to study was the carpenter’s suggestion about a binder for special solutions at inadequate constructions and difficult situations. The developed instruments as well as the method used in our report to counteract reoccurring problems and disturbances in the production, contribute to the work in reaching the company’s goal to promote cooperation within the organization.
