Vädrets påverkan på byggarbetsplatsen

This exam report contains studies about how the weather affects the construction site from a planning and productivity perspective. In 1960?s the contractors started to build during the winter, since then the demands to obtain a good construction has been higher on both the contractor and then promoter.In this report you will see how the different actors at the construction site handle the weather problems. By several interviews of the actors at the construction site there have been opinions about the weather situation which has been collected. To get a wide perspective of the problem, field studies from four different construction sites been made.Weather statistics over Halmstad is a mayor part of this report.

Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) in coastal areas of northern Sweden

Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) was studied on 12 sites in coastal areas of northern Sweden. On each site, sample plots were placed in adjacent Norway spruce and Scots pine stands with similar ages in between. Basal area, tree height, Site Index, volume production, simulated maximum mean annual increment (MAImax) and tree vitality were compared for the two species. Average basal area at the time of measurement was 30.4% larger for Scots pine stands than for Norway spruce stands. The difference between the two species in basal area increment during the last 10 years was related to stand age.

Tidsstudie av containerhuggbil

The fork lifter chipper truck is a concept which has been developed for harvest and transport of bio fuel. The system consists of one fork lifter chipper truck and 1, 2 or 3 transport lorries, usually two, which serves the fork lifter chipper truck. The system is driven by the fork lifter chipper truck that produces chipped material into a container on the truck. When the container has been filled the truck drives to the landing site where it?s offloaded.

ANVÄNDNING AV PRODUTIVITETSVERKTYG FÖR ATT NÅ UPPSATTA PROJEKTMÅL : En undersökning på ett Skanska projekt

This is a result of a diploma work in construction engineering. The purpose of this thesis is to investigate the nature of the productivity in a given project and how the Skanska productivity tools were used in this project.Interviews were held among workers and management to get some answers on what affected the work and its productivity. The result of the thesis showed that the productivity tools as propulsion analysis and ?goal cards?, were not used to a wide extent in this project. Furthermore there was almost no feedback for the one who made the calculation and the offer for the project, which might affect the results on projects negatively in the future.Within the project there was a lot of waiting time which affected the productivity.

Produktivitetsstudie Brobyggnad

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd

The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest Site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

En modell för att kostnadseffektivt öka produktionen inom aluminium-bearbetning

The purpose of this study is from a case study develop a model that aims to cost effectively improve productivity in a manufacturing production process. The study highlights the importance of having knowledge about customer needs and using a holistic process perspective when improving productivity to identify the relations between the process stations and by this find problems that cause waste and losses in productivity. Tools and methods used to make production more efficient such as single minute exchange of die, spaghetti diagram, 5s and master production schedule is presented an applied in the model to see how these effect costs, productivity etc.Maintenance effects on quality and productivity in a manufacturing company will as well be covered in this thesis. The results and conclusions finally reveals how the process improvement tools, maintenance and production planning for example effects each other and why it is important to establish an attitude in the company where continuous process improvement should be emphasized..

Redesign av en hemsida : Med sökmotoroptimering och användbarhet i fokus

This paper describes the redesign of a site (Kolonn.se). Some of the problems with the site were a lack of structure and a design that was unclear both visitor and search engines. The site now has a new design and structure that has been taking form in Axure prototypes that has been tested and applied into WordPress. The results are a site with a new main menu, new graphic profile and logo. Also SEO-adapted content such as correctly structured headers, meta tags, descriptions and key words that has been implemented in the content.

Produktivitetseffekter av flerträdshantering

The main purpose of this study is to investigate the productivity effects of multiple tree handling in thinnings. Other important elements have been to investigate in which extent multi-tree handling is used in stands with different stem volumes and the impact of collecting partially delimbed fuelwood assortments has on harvesting performance. The study is based on data from thinnings in Sydved and contractors' operating activities. Collection and compilation of operating schedules, number of stems and surveyed volumes from several contractors and a large number of executed orders underlying the results. Multiple tree handling is used to a much greater extent at lower average stem volumes. Prediction models for productivity of the multiple-tree handling harvesters in the study differ from the productivity models for single-tree handling. In the model developed in this study productivity is not as dependent of stem volume as reference models.

Camping : Vad, Vem & Varför!

What on earth do people see in camping? Why do they choose this compact living in their holiday? All that people in caravans who are put together in a camp site.The purpose of my study was to find out who and wy. My ethnographic study in a camp site with participation observations, interviews and analysis have results in facts that show why.The most common camper is the house owner with average income. And the choice of the camp site depend on the security and the service that the camp site offered. The camp site was controlled and the campers controlled each other.

PLATSCHEFENS FÖRMÅGA ATT ÖKA PRODUKTIVITETEN - en jämförande studie av fyra arbetsplatser hos Peab -

studier visar en låg produktivitet jämfört med andra branscher men också komplexiteten av produktivitetsmätningar. Syftet med rapporten är att undersöka platschefens roll och vilka faktorer som påverkar förmågan att få ut produktiviteten på en byggarbetsplats. Fallstudien genomfördes på fyra av Peabs projekt och frågeställningen besvarades med hjälp av kvalitativa och kvantitativa metoder i form av intervjuer och enkätundersökningar. Vidare undersöks produktivitetspåverkande faktorer såsom kommunikation, motivation, kompetens och samarbete. Vid jämförelse används en incitamentkvot som ställs i relation till enkätundersökningarna och intervjuerna.Resultatet visar tydliga skillnader mellan platschefernas förmågor, arbetssätt och egenskaper som leder till en skillnad i produktivitet på arbetsplatserna.Slutsatsen visar vilka egenskaper och arbetssätt som tenderar i att ge en hög produktivitet..

Stora Södergatan : communicating a street´s potential through site reading

In urban planning and design today interventions tend to take place in already existing areas and inevitably effect also surrounding areas. The many parties involved in any change leads to a demand for a shared language around these areas. This thesis aim to, through understanding and communicating a site, Stora Södergatan in Lund Sweden, inspire to a novel way of looking at an urban site preceding design- or planning interventions. Based on a theoretical framework where site is considered as a relational construct, material as well as immaterial, a framework for site thinking is constructed. Further, with theory of representation, the communication of the site is emphasized and accounted for as part of the framework.

Med Lean i bagaget - En studie om Leans förmåga att öka produktiviteten av en bagagehanteringsprocess

Although Lean has received an increased amount of attention in the service context, research still has not established how successfully Lean manages to increase service productivity; since service productivity consists of both efficiency and quality. Research regarding productivity discusses the risk of a tradeoff between efficiency and quality in service production processes. Therefore, this thesis aims to explore if the tradeoff in a production setting with low variability in demand and low customer participation exists, after Lean has been implemented. With a qualitative approach, a case study has been conducted at Scandinavian Airlines Ground Handling to evaluate the effects of Lean in the baggage handling process. The result of the study shows that the tradeoff has not been overcome; efficiency has increased at the expense of quality.

Produktionschefens arbetssituation : Hur deras arbete kan förändras och utvecklas

This report is written in cooperation with Skanska Sverige Hus Väst and it is discussing the role of site managers within the company. The report will bring up the demands that is put upon site managers and will also discuss stress related problems and how to change and develop the role as a site manager.We came up with three conclusions in this report. We believe that Skanska could develop VSAA to make it easier to use for site managers. We also believe that a further development of the project engineer is of great value, to give him or her greater responsibilities. The last conclusion is to change the responsibilities between the site manager and the production manager, to give the production manager a greater responsibility in the production..
