Abstract:
This paper focuses on sustainable transportation of prefab products from factories to construction sites by ship. Since the transportation cost for all the prefab products of a construction site is mainly dependent on the number of cargo holds used on ships, a loading plan for prefab products that minimizes the number of holds required is highly desirable. This paper is therefore devoted to the development of an optimal loading plan that decides which prefab products are loaded into each cargo hold and how to pack these prefab products into the holds so that as few holds as possible are used. We formulate the problem as a large-scale integer optimization model whose objective function is to minimize the total number of cargo holds used and whose constraints represent the cargo hold capacity limits. We develop a heuristic to solve the problem and obtain a high-quality solution. We have tested the model and algorithm on a case study that includes 20 prefab products. We find that different cargo holds carry prefab products that have quite different densities. Moreover, the orientations of many prefab products are different from their default orientations. The results demonstrate the applicability of the proposed model and algorithm.

Abstract:
The paper focuses on the development of a thermal protection and energy requirements in relation to the issue of prefab residential housing buildings and prefab housing estates while emphasizing the need for a conceptual approach and environmental considerations. The development is recapitulated with examples of compositional sets of prefab residential housing on selected sites in the Czech Republic. Based on the comparison of archival documents and results of a long-term observation of the prefab residential housing resources, it outlines the direction of further expected development of prefab housing estates within a social context. The comparison also takes into account the impact of the European Union energy strategy and the implementation of directives into the legal rules and standards of the member states. The aim of the paper is to show the negatives and positives of current political and social strategies in relation to the thermal protection of buildings, the energy management and healthy indoor environment, and that the renovation of prefab residential housing and prefab housing estates is effective with regard to the invested funds.

Abstract:
The paper study the deformation characteristics of the Prefabricated bamboo reinforced porous concrete slab through points with four points focused beam loading method. The results show that flexural behavior of prefab slab can be improved by adding bamboo reinforcement. Along with the increase of bamboo reinforcement ratio, deflection of prefab board will gradually reduce. Through the loading deflection curve, we can discover that the bamboo reinforced prefab slab with the linear elastic state, and the slab can withstand a certain load after cracking. Bamboo reinforced with strengthening and toughening effect for porous concrete, prefabricated bamboo reinforced porous concrete plate can be used better in slope protection engineering.

Abstract:
In South Korea, radiant floor heating has been used from old housing to the recently constructed residential buildings, which is called “Ondol”. The Ondol system is generally a water-based system and it uses hot water as a heat medium provided by boilers fueled by natural gas. With great effort to reduce greenhouse gas emissions, electric Ondol panels have been increasingly applied to the recent residential buildings for floor heating. While the prefab electric Ondol panels were developed with the demand for dry construction method, the information about the prefab electric Ondol system is not sufficient. For the present study, the thermal performance of the prefab electric Ondol panels was investigated through field measurement. In addition, the heating energy and economic performance of the electric panel were compared with the conventional Ondol system. As a result, a significant surface temperature difference was observed. Moreover, the heating cost for the prefab electric Ondol system was more expensive than the conventional system, even though a heat loss was observed by the operation of the conventional system.

Abstract:
Under the India “Housing for all” scheme, 20 million urban houses have to be constructed by 2022, which requires the rate of construction to be around 8000 houses/day. Previous results by the team show that present design methods for affordable buildings and structures in India need improvement. The challenges are the disposal of solid waste generated from agro-industrial activities and the energy peak demand in extremely hot and cold seasons. The development of bio-based urban infrastructure which can adapt to the climatic conditions has been proposed. Inclusion of sustainable materials such as agro-industrial by-products and insulation materials has resulted in effective environmental sustainability and climate change adaptability. Precast components are highlighted as a suitable solution for this purpose as well as to fulfil the need of mass housing. India has a lesser record in implementing this prefab technology when compared to a global view. For the first time, a novel and sustainable prefab housing solution is tested for scale-up using industrial waste of co-fired blended ash (CBA) and the results are presented here. A model house of real scale measuring 3 × 3 × 3 m3 was considered as a base case and is compared with 17 other combinations of model house with varying alignment of prefab panels. Comparison was made with commercially available fly ash brick and CBA brick with a conventional roof slab. A simulation study was conducted regarding cost and energy analysis for all the 18 cases. Various brick and panel compositions with CBA for housing were tried and the superior composition was selected. Similarly, 18 model houses of real scale were simulated, with different combinations of walls made of bricks or panels and different building orientations, to check the impact on energy peak cooling and cost. Results show that peak cooling load can be reduced by six times with bio-based prefab panels. Prefab construction can be considered for mass housing ranging above 100 housing units, each consisting of an area of 25 m2.

Abstract:
Stora problem med fukt i byggnader som kan relateras till så kallad byggfukt rapporteras årligen. Problematiken med tätt ytskikt på betong uppmärksammas i större utsträckning. I skolor och på sjukhus där det ofta finns krav på lättstädade miljöer är problemet som störst, då det i dagsläget enda alternativet verkar vara en tät plastmatta. Att lägga ett tätt ytskikt på betong ställer krav på uttorkning av konstruktionen, betongen ska ha en relativ fuktighet (RF) som är högst 85% innan plastmatta får läggas. Detta för att undvika att fukten i konstruktionen bryter ner limmet, vilket på sikt skulle kunna orsaka skador på byggnader i form av mögel och mikrobiell tillväxt. Personer som vistas i dessa miljöer kan uppleva hälsobesvär. I form av huvudvärk, trötthet, koncentrationsbesvär, irritation och torrhetskänsla i ögon, näsa, hals och hud. Detta examensarbete är en studie genomförd i samarbete med UBAB, Ulricehamns betong, som syftar till att jämföra inverkan av förhållandet mellan vatten och cement (vct) i betongreceptet samt hur förvaringsmiljön påverkar RF. Tre av UBAB:s recept har jämförts. Varav ett recept med lågt vct som är framtaget specifikt för att förkorta uttorkningstiden. För varje recept gjöts två plattor, där den ena förvarades utomhus och den andra inomhus under perioden slutet av januari till slutet av maj. Mätningen av RF skedde genom borrhålsmätning enligt RBK:s manual för fuktmätning. En jämförandemätning gjordes också med uttagsprov. Resultaten visade tydligt att plattorna som förvarades inomhus hade ett lägre RF än de som förvarats utomhus. De recepten med lägre vct hade ett lägre RF än de med högre vct. Av de plattor som förvarades utomhus hade plattan med lägst vct det lägsta RF, vilket var högre än RF hos samtliga plattor som förvarats inomhus. Uttagsproven bekräftade detta, även om dessa resultat kraftigt underskattade RF. En jämförelse mellan prognosvärden i TorkaS och borrhålsmätningen visade att TorkaS inte överensstämmer med de avlästa värdena. TorkaS prognostiserar högre RF för prov som förvaras inne. För prover som förvaras ute beräknas ett lägre RF än avläst.
Major problems with moisture in buildings that can be related to so-called building moisture arereported annually. The problem with dense surface layer on top of concrete slab becomes more common. In schools and hospitals, the environment requires floors that are easy to clean, and the only solution is to use a plastic mat. A plastic mat on a concrete slab demands that the relative humidity (RH) must be below 85 %. This to prevent moisture from dissolve the glue which could lead to microbial growth and mold. People staying daily in this kind of environment could suffer from health issues. Suchas headaches, fatigue, concentration problems, irritation and dryness in eyes, nose, throat and skin. This report in collaboration with UBAB, Ulricehamns betong, is comparing how the different recipes of concrete and the climate of storage will impact on RH. The recipes used are three of UBAB: s standardrecipes. One recipe with low water-cement ratio wich is created to shorten the time for the concreteto dry. Two slabs are made for each recipe, one is stored outdoors and the other one indoors during the period January to May. The method used to measure the RH is by drilling hole in the concrete and make measurements according to RBK standards. A comparing study is made with removed concrete from slab to test tubes. RH is then measured in a climate cabinet. The results show that slabs stored indoors have a lower RH compared to the slabs that have been stored outdoors. The slab with low water-cement ratio stored outdoors has the lowest RH of the outdoor slabs, but still higher than all slabs that have been stored indoors. Results from test with removed concrete confirmed how the environment of storage has large impact on the speed of drying. Although the values of RH were too low to be trusted. Calculations made with TorkaS does not match the results from measurements. TorkaS overestimates RH for slabs stored outdoors. RH for slabs stored indoors are underestimated by TorkaS.

Abstract:
This is an investigation of a mobile prefabrication factory´s competitiveness and profitability which also will result in a suggestion for a design of the factory. The mobile prefabrication factory is an idea of a new concept for production which is meant to be used in the manufacture of slab. The main intention with this concept is that by using a fast established prefabrication factory to produce elements near the construction site, thus avoiding transport from the factory to the building site. This means not only an environmental and economic gain, but also that you can avoid risking damage the elements which often occur during transportation. The contractor is owner of the mobile prefabrication factory and can thus avoid long waiting times and cyclicality. These are parameters that often can be a concern when using prefabricated element from factory´s off-site. When the building is finished, the prefabrication factory is able to be packed onto trucks, moved, and reestablished close to next building site. The portable production capacity also means that production can be kept close to the product development and can therefore quickly test new solutions, thus this concept facilitating a continuous improvement.   After a rough estimate of the cost for the establishment, operation and maintenance turned out that the mobile prefabrication factory needs to be established by large projects that require more than 7 970 m2 of slab in order to recoup these expenses. Then to recoup the investment cost of 5, 64 million crones the project must have a need for more than these 7 970 m2 of slab. Counting on a life expectancy of 30 years for the mobile factory, the factory needs to produce 1 568 m2 of slab á year, in addition to the slab required for accrued cost for establishment.

Prefabricering eller platsbyggt hus? Många ställer sig den frågan. Vad finns det för fördelar respektive nackdelar med prefab

gentemot platsbyggt hus? Vilka ritningar behövs och hur går man tillväga?

Detta examensarbete är en framtagning på hur man anpassar ett småhus till prefabricering.

Platsbyggt hus är ett hus som byggs på plats. Material fraktas dit, förvaras och kapas.

Den vanligaste byggmetoden för byggande av hus.

Prefabricering av hus är däremot ett hus som byggs i en fabrik eller industri. Huset byggs i färdiga block som kan innehålla

fönster, dörrar, el och vattenledningar etc.

På arbetsplatsen lyfts blocken på plats och monteras ihop.


Prefabricate or on-site made house ? Many ask that question. What are the advantage and disadvantage with prefabricate

towards on-site made house ? Which drawings need to be done and how do you draw them?

This diplomawork deal with how you adjust a house into prefabricate.

On-site made house is a house that is build on place. Materials freights there, stores and bucks. The most common

construction method.

Prefabricated house is however a house that are built in a factory or in a industry. The house build in complete blocks and

can include things like windows, doors, electricity and pipelines etcetera.

At the workplace they lift the blocks in place and assembles together.

Abstract:

The Results of this thesis was the creation of two designed house variants with a module to

all the apartments. In addition till the first module there are three other modules of

apartments that can be put in the houses if it so needs. The house are volume prefabricated

and are placed on site in a way that it create an enclosure of the area which faces against the

nature and car parks also lies hidden behind these houses.

For the actual structure, a cross beam was created to carry the floor above and it is support

by all four walls. The structure between the first and the second floor has no "syll" but

instead there are two differently alternative to linking the floors in order so that it will not

move. The reason with this solution was that there will not be any subsidence when the

forces from above are pressed down ward. The forces are instead directly down to the next

timber frame system. This can happen when the real estate's owner might want to build

more floors on the house than the present two floors house when there is no land to build

and spaces are needed in the future.

Abstract:
Prefabricering av väggelement är en byggmetod under stark framväxt i byggandet av småhus de senaste decennierna. Kostnadseffektiviteten nämns ofta som ett skäl till att prefabricering av småhus har en sådan stor framväxt. Samtidigt har miljö- och klimatfrågan växt och då byggsektorn står för en stor del av Sveriges koldioxidutsläpp krävs det att byggsektorn ställer om till ett allt med hållbart byggande. Detta examensarbete har undersökt denna kostnadseffektivitet och hur och om en går att kombinera med ett hållbart byggande och sedan jämfört detta med platsbyggda väggar i trä. Underlag har tagits fram i samarbete med Skidstahus som producerar prefabricerade väggelement i fabriksmiljö och underlag från Derome Hus AB/ VarbergsHus vad berör småhus i lösvirke. En kostnadsjämförelse av de två byggmetoderna visar att de prefabricerade väggelement som Skidstahus framställer är mer kostnadseffektiva och det beror till stor del på att arbetstiden effektiviseras. Till viss del visar examensarbetet att materialanvändningen även resurs effektiviseras vid Skidstahus produktion och resulterar i mindre spill som därmed gynnar ett hållbart byggande. Andra viktiga aspekter för hållbarhet och livslängd såsom fukt och lufttäthet visar att prefabricerade väggar har utmaningar då skarvar och anslutningar måste vara väl utförda. Samtidigt innebär arbetet i fabriksmiljö att risken för fuktproblem minskar då det ger ett skydd för klimat och väder. Detta är medför även att byggarbetarna får en god och vältempererad arbetsmiljö. Däremot finns frågetecken kring hur byggande med prefabricerade väggelement påverkar miljön i form av transporter i förhållandet till platsbyggda väggar av lösvirke, då transporter till och från fabrik krävs. Utöver detta påverkar byggmetoden hur gestaltning och arkitektur utförs då ett platsbyggt hus i trä enklare går att utföra med valfri gestaltning. Analyserna visar sammanfattningsvis att användandet av prefabricerade väggelement i trä reducerar byggkostnader samtidigt som det kan bidra till ett hållbart byggande. Det krävs dock ytterligare studier för att jämföra den beräknade livslängden på prefabricerade väggar och platsbyggda.
Prefabrication 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.

Abstract:
Enligt uppskattningar byggs 40 % av alla projekten på Skanska Jönköping med en prefabricerad betongstomme. Detta kan anses lite i förhållande till Skanska Sverige där ca 70 % av alla projekt byggs med en prefabricerad stomme. I resterande projekt byggs betongstommarna på plats, d.v.s. de är platsgjutna stommar. I och med detta så finns det en stor potentiell utveckling för prefabricerade betongstommar inom Skanska Jönköping, men även för resterande Svenska byggföretag då 2/3 av alla flerbostadshus uppförs med en platsgjuten stomme. I rapporten tas de ekonomiska för- och nackdelarna för de olika stomtillvägagångs sätten upp, hur yttre förutsättningar kan påverka projekten och hur de mjuka parametrarna påverkar den utförande organisationen. I rapporten definieras mjuka parametrar som stress, motivation och personskador/slitage. Syftet är att underlätta valet av stomme så att det blir mer ekonomiskt hållbart, att bättre trivsel på arbetsplatsen uppnås samt att ge en ökad kunskap om prefabricerade stommar och platsgjutna stommar. Underlag för rapporten har tagits fram genom litterarutstudier och intervjuer med anställda på Skanska Jönköping med olika befattningar. Även en enkät undersökning har gjorts bland yrkesarbetarna på Asken och Atollen, två projekt som har byggts i Jönköping. Asken har en platsbyggd stomme medan Atollen har en prefabricerad stomme, dessa två har varit referensprojekt till rapporten. Den stora skillnaden mellan en prefabstomme och en platsgjuten stomme är tiden. Enligt studier kan byggtiden minska med 22 % vid prefabricering och detta medför mervärden för både samhället och företaget. För entreprenören påverkas valet av stomme av yttre förutsättningar som ritningsunderlag, erfarenhet och leverantörernas situation. Var och en av dessa kan påverka priset på prefab upp till 20 %. Från genomförd enkätundersökning på Skanska i Jönköping framgick att 69 % av yrkesarbetarna upplevde att det oftare blev övertid på platsgjutet. Ökad arbetsmängd och ökat arbetstempo leder både till stress och slitage.

Abstract:
Av världens totala utsläpp av koldioxid står cementindustrin för ungefär 8 %, vilket är ungefär två gånger så mycket som flygindustrins utsläpp. Koldioxidutsläppen orsakas främst genom den energikrävande metod som används när cementklinker ska framställas från kalksten samt koldioxiden som avges vid den kemiska processen som sker under förbränningen. Nya cement- och betongrecept, med nya egenskaper framställs med målet att minska koldioxidutsläppen. Detta examensarbete är en studie genomför i samarbete med UBAB, Ulricehamns betong. Målet är att hitta möjliga sätt att reducera koldioxidutsläppet relaterat till betongelement genom att ändra på betongrecepten. Tre olika betongrecept med olika tillsatsmaterial har undersökts: glasfiller, slagg och flygaska. I försöken har 30% av bindemedlet ersatts med ett av tre tillsatsmaterial. I samtliga försök har CEM II använts. Syftet var att undersöka betongen med tillsatsmaterial med avseende tryckhållfasthet och arbetbarhet samt jämföra med referensbetongen när det gäller självuttorkning. Resultat av tryckhållfastheten efter ett dygn visar att receptet som innehåller glasfiller hade den största tryckhållfastheten på 20 MPa, följt av receptet med slagg på 19 MPa och sist med flygaska som hamnade på 16 MPa. Tryckhållfastheten mättes ännu en gång efter 28 dagar och resultaten blev 53,2 MPa för receptet med glasfiller, 50,2 MPa med slagg och 48,1 MPa med flygaska. Betongplattor har gjutits med referensbetong och betong med de tre tillsatsmaterialen för att jämföra uttorkningsprocessen med referensbetongen.
Of the world’s total carbon dioxide emissions, the cement industry accounts for about 8 percent, 3 which is about twice as much as the aerospace industry. Carbon dioxide emissions are mainly caused by the energy-intensive method used when cement clinker is to be produced from limestone and by carbon dioxide released during the chemical process that takes place during calcination. New cement and concrete recipes, with new properties, are prepared with the goal of reducing carbon dioxide emissions. This thesis is a study conducted in collaboration with UBAB, Ulricehamns Concrete. The goal is to find possible ways to reduce their carbon dioxide emissions by changing their current concrete recipe. Three different concrete recipes with different additives have been investigated. In the tests, 30 % of the binder was replaced with one of three additives. The three additives were glass powder, blast furnace slag and fly ash. CEM II has been used in all experiments. The purpose was to investigate the compressive strength and workability of the new concrete mixes and investigate if the selfdrying changes in comparison to the reference concrete. Results of the compressive strength after one day show that the recipe containing glass filler had the highest compressive strength of 20 MPa, followed by the recipe with slag of 19 MPa and fly ash 16 MPa. The compressive strength was measured again after 28 days and the results were 53.2 MPa for the glass filler recipe, 50.2 MPa for slag and 48.1 MPa for fly ash. Concrete slabs are casted with reference concrete and with the three secondary cementitious material replacements in order to compare the relative humidity in the slabs with the reference concrete.

Abstract:
This thesis conducted at the University of Uppsala investigateshow well a prefabricated building component from the manufacturerMasonite Lättelement AB can be incorporated into ahouse projected to accomplish the demanding criteria of a passivehouse. The thesis is organized as a comparison betweenthe prefabricated elements and an on-site built component fromthe passive house area of Oxtorget in Värnamo, Sweden. Theaspects investigated were air leakage, energy, moisture, economyand noise conditions.Results of the comparative analyzes shows that the prefabricatedproducts were capable of accomplishing the requirementsof passive houses and therefore this thesis should beviewed as a basis to confirm that the technology of prefabricatedbuilding components today in Sweden are mature enoughto be a significant part of the passive houses that are to be builtin the near future. The development of prefabricated technologyis of crucial significance if we are to accomplish the goalsof reduced energy consumption by the year 2020.
