Full textThe decision about which constructing method that will be used must be taken in an early stage of planning. There are many different methods in order to construct one and a same part of a building. In this report, we describe two construction methods for flooring elements. The choice of construction method is a current question on Åhlin & Ekeroth AB and the company is on an expansive advance. In order to make their methods more efficient the task of investigating this matter has been given to us. Our main goal is to decide whether it is more appropriate to build a flooring element on-the-spot or with prefabricated flooring- cassettes. We had the possibility to observe an ongoing project in a district called Lambohov and decided to make an investigation of which type of wooden beam is most suitable for small buildings. We mention two kinds of beams in this report. One of them is called the masonitebeam and the other one is an ordinary beam. In order to give the report a larger genuine value we implemented interviews of persons with appreciable experience within the construction industry. Their opinions and knowledge has been to a big assistance in our researching. It has also emerged a lot of exciting facts due to our strategy to give the persons plenty of room during the interviews. In order to get closer the truth about which construction method that is most appropriate for small houses we also performed some economical calculations. Despite of everything it is the economic factor that often decides which constructing method that will be used. We know that the prefabricated flooring- element has a higher price and installation cost but is constructed much faster. The question of which constructing method is the economic most favourable in contrast to the total cost remains to be answered and we would recommend a wider research in this matter. We hope that the report will be a basis in the future for Åhlin & Ekeroth AB when the company carries out similar projects as the ones on Kv Isglassen and Kv Isskulpturen.

Full textPrefabrication of wood wall elements in construction of villas and terraced houses is a building method undergoing growth in recent decades. Cost efficiency is often cited as a reason why prefabrication has undergone such a large growth. At the same time, the issue of environmental impact and climate change has grown. As the construction sector accounts for a large part of Sweden's carbon dioxide emissions, the construction sector needs to become more sustainable. This thesis has examined this cost-effectiveness and if it is possible to combine with environmental sustainability. To examine this more thoroughly a comparison is made with in site-built timber-framed constructed walls. The thesis has been conducted in collaboration with Skidstahus, which produces prefabricated wall elements in a factory environment, especially for data collection. Information and data have also been collected from Varbergshus / Derome producing houses in site-built timber-framed building. A cost comparison of the building methods shows that the prefabricated wall elements manufactured by Skidstahus are more cost-effective, which can be linked to work efficiency. To some extent, the thesis also shows that material use can be optimized at Skidstahus production and therefore results in less waste, which thus reduces environmental impact. Other important factors for durability and accounted life span is the building method’s ability to handle migration of moisture and airtightness. The thesis shows that prefabricated walls have challenges, as joints and connections must be well designed. At the same time, factory production allows an environment which can reduce risk of migration of moisture as it provides protection for climate and weather impact. Another aspect is that it provides a good and well-tempered work environment for the construction worker. On the other hand, it is questionable whether the use of prefabricated wall elements affects the environment as it may increase the need of transportation in relation to on site-built timber-framed walls, as transport to and from the factory is required. In addition, the prefabricated method could influence how design and architecture is carried out while a wood house made from stick timber is more easily modified. In summary, the analysis show that the use of prefabricated wood wall elements reduces building costs while at the same time it can contribute to environmental sustainability. However, further studies are required to compare the estimated life span of the two compared building methods.

Full textCon-Form AS är en norskägd stomentreprenör som projekterar och egentillverkar byggdelarsåsom vägg, bjälklagselement, pelare, balk, trappor och våtrumsmoduler. Att tillverkavåtrumsmoduler är en relativt ny och obeprövad byggteknik i Sverige gentemot platsbyggdavåtrum. Anledningarna till valet av en specifik produkt är priset och kvalitén.Den prisjämförelse som utförts i denna rapport är framtagen utifrån produktion av tjugofyravåtrum. Våtrummet som har kostnadskalkylerats är på 5,9 m2 och består av en toalett, ettduschset med draperi samt ett handfat med tillhörande underskåp och armaturer.Kostnaden för våtrumsmodulen har tagits fram av Con-Form Töcksfors AB och kostnaden fördet platstillverkade våtrummet av NCC Karlstad i samarbete med underentreprenörer. I dettafall blev summan för det platstillverkade våtrummet 52 500 SEK och summan förvåtrumsmodulen 50 900 kr. Vid byggnation av platstillverkade våtrum blir de indirektakostnaderna mer omfattande. Indirekta kostnader är exempelvis ökad material- ochavfallshantering på byggarbetsplatsen. Våtrumsmodulen är därmed det billigare alternativetav de båda.En fördel med det förtillverkade våtrummet är delvis minskad materialhantering påbyggarbetsplatsen då modulen levereras vid inbyggnadstidpunkt och med kranlyft placerasdirekt i byggnaden. En nackdel med våtrumsmoduler är att dessa tidigt behöver komma in iprojekteringen och kunden låser sig därmed vid valt våtrum. Våtrumsmoduler passar därmedbäst i hotell och hyresrätter där det är en och samma beställare som tidigt i projekteringenbeslutar över utseende av våtrummen.En fördel med platsbyggnation är möjligheten att anpassa våtrummet efter kundens tycke ochbehov längre fram i byggskedet. Detta kan vara en avgörande faktor vid försäljning avexempelvis bostadsrätter. Däremot blir kostnaden för våtrummet dyrare vid platstillverkningoch logistik samt materialhantering blir mer omfattande.

Full textSyftet med examensarbetet är att göra en jämförelse mellan prefabricerade och platsbyggda tak. Arbetes mål är att finna om något av alternativen är mer fördelaktigt än det andra med avseende på ekonomi, arbetsmiljö och kvalité. Två olika byggarbetsplatser har besökts för att samla in kunskap om hur arbetet går till. För prefabricerat tak har bygget av en eventhall i Kristinehamn studerats och för traditionellt platsbyggt besöktes en sporthall i Årjäng. Genom litteraturstudier och intervjuer med leverantörer och insatta personer i branschen har kännedom skaffats.
Prefabricerade tak har använts med stor framgång i Norge under en längre tid men är inte lika vanligt här i Sverige. Genom att öka förståelsen för för- och nackdelarna med prefabricerade element kan dessa utnyttjas med större framgång. Genom att branschen pressas hela tiden att bygga snabbare och billigare kan prefabricerat vara en väg att nå dessa mål.
The main purpose with this diploma work is to compare the two production methods, premanufacturing and on-site construction. The goal is to deduce if one of the alternatives is more attractive than the other in view of economy, work environment and quality. To gather information about how the construction works, two various construction sites have been studied. The premanufactured roof was studied in Kristinehamn during the construction of an eventhall and for the on-site construction a sport arena in Årjäng. Information was also gathered through a literature study and by interviewing active persons in the building industry.
The premanufactured roofs have been used in Norway with great success during a long period of time but are not that common here in Sweden. By increasing the understanding of the advantage and disadvantage of premanufactured building elements, they can be used with greater success. The building industry has under some time been pushed to build cheaper and faster, maybe the premanufactured element is the way to achieve this goal.

Full textThe premise of this thesis is a comparison study of which prefabricated bathroom modules are compared to on-site built bathrooms from an economic, time and quality standpoint. This work is done in collaboration with Gunnar Prefab AB where a survey is carried out based on 300 fictitious bathrooms. The main objective of this work is to develop a cost estimate, a timeline and the quality aspects for each method. The purpose is to provide guidance when choosing what production method is the most optimal choice when producing bathrooms. The comparison is based on a self-made quantity list and the bathrooms are examined under arbitrary conditions in new production. The survey has also been limited to one contractor and one specific architectural plan. The thesis starts off with a theoretical reference framework which is considered as the foundation of this report. In this chapter, an explanation is carried out on how the production of a bathroom is constructed for each method and the theory behind the production of a cost estimate. Lastly, an explanation is given on how the timeline and the quality aspects are developed throughout the project. The following subheading presents the approach of calculating direct and common costs and the implementation of the comparison in time and quality. It proved difficulties to make a cost comparison based on a project as large as 300 bathrooms do to that literature in this subject showed different figures revolving the cost issue. The result of collected quotes and cost calculations gives a total of 17 533 544 kronor for the prefabricated bathroom modules and 18 290 691 kronor for the built on-site bathrooms. To compare the quality and its advantages, disadvantages and quality- and management systems were examined from a quality point of view. The results concluded that the quality of the prefabricated modules was slightly better due to the fact that they were manufactured under a controlled environment. The main difference between said construction methods was the construction time. For the prefabricated bathrooms it took 34 weeks to produce and for the built on-site bathroom it took 102 weeks. The conclusion of this thesis is that the prefabricated bathroom could be the cheaper option only if the project would be of a larger scale and could be a better choice from a time-saving perspective. One recommendation when selecting this method is that the contractor needs to be involved from an early stage in order to reduce construction time and lower the costs. For projects with several different type of bathrooms where they have different layouts, it is recommended to combine the prefabricated method with the built on-site, as modules can’t be implemented for plans with smaller WC. Due to the high pressure on the market, it can be difficult to obtain materials and labour, which can lead to consequences for the end result. In projects where time and cost is of essence, the prefabricated modules may be preferable when produced in a factory that runs by the assembly line principle.
