Sticklingsetablering av Sedum spp. för gröna tak : biokol som organiskt material i substrat
The popularity of vegetated, or green roofs, has grown over the past years due to their potential
function of maintaining urban environment quality. The aim of this study was to investigate if
substrates with different organic material, peat and charcoal, with two contents (3 or 6 weight%)
influenced the growth of the cuttings during the first critical period of the establishment. Biochar is
used as amendment to agricultural soils and has, theoretically, many of the properties suitable as
organic content in green roof-substrates. Peat is one of the materials that is commercially used in
green roof industry. The substrate has been treated with different amounts of water.
Finanskrisens inverkan på byggbranschen
Recently there have been a lot of talk a about the financial crisis and recession. This is understandable since the crisis, which initially was limited to the U.S. now has spread its concern globally in form of bankruptcies, less investment and lots of people have lost here jobs. The purpose of this thesis is to examine how the financial crisis have affected the construction industry relating to market and personnel, but also examine what measures the construction companies have taken. The examination was carried out by information received from the majority of construction-related websites which then was followed up with interviews in the various construction sectors.
Tekniska system i förskolan : 3-5 åringars uppfattningar om mobiltelefoni
This report will describe a project between two students from Karlstad University and Markus Norström from Hovercraft solutions. The project aim was to develop a cabin for the hovercraft 380TD. The project was divided into two sub parts; one concerning the design of the cabin and one concerning the engineering. Throughout this rapport you can follow the engineering part of the project. The project has followed a systematic product development process resulting in optimized results for material selection and engineering solutions.
Samarbete i byggprocessen : entreprenörens förväntningar på byggherren
Everywhere you look in today?s society many kinds of people are constantly interacting with each other. Especially in large groups of people working together, the phenomenon is even greater. In the construction industry there are many kinds of parts that need to come together in order to get sustainable and successful results. Therefore the relationship between the contractor and the construction client must be at its best.
Fallstudie av kostnader i tornsilo och plansilosystem på en mjölkgård :
I have through a case study looked on a milkingfarm in Dalarna and been counting on
what it would cost to increase the silagestorage. Today they have to little capacity on the
existing towersilo because they built a bigger farm with more cows. The reason is that
two families decided to start having the production on one farm together and moved all
animals from one of the farms to the other farm. So for that reason I have looked on the
costs to build a new towersilo or levelsilo.
The goal has been not only to look at the buildingcost but also which operatingcost that
is included with the different alternatives. I have taken tenders from two different
towersilocompany, Bjurenwall and Svenska Neuero and taken tenders from Abetong for
a levelsilo with roof and one without roof.
The overall feed requirements on the farm is on 240 tonnes dry extract and the old
towersilo hold 110 tonnes dry extract so the need for a new foundation is on 130 tonnes
dry extract.
I have through cost estimate been counting on the specific buildingcost for each
buildingaltenative.
Byggdamm : Vad krävs för att minimera spridningen på ROT-projekt under produktionsskedet
Dust that arises during the construction process is called ?construction dust?.People who are exposed for construction dust for a long period of time are atrisk to develop several forms of lung problems, allergies and cancer. Todayconstruction dust is a huge problem during the production in Skanska´srenovation projects. Every day workers are exposed of the unhealthyconstruction dust and it can cause lung problems and diseases after 10-30years. This is a problem that must be taken into account to obtain a betterworking environment on Skanska´s building sites.Skanska Sweden AB has given two students the task to investigate possibleproblems about the spreading of construction dust.
Kriminalitet sätter mannen på prov ? En studie av identitetsskapande i romanen Snabba Cash.
The aim of this Master?s thesis is to examine how representations of identity construction are performed through the characters in the novel Snabba Cash by author Jens Lapidus. I examine what means the characters are using, and how the identity construction processes are related to the idea of modern society. For a theoretical background I use sociologist Anthony Giddens? theories regarding modernity and self-identity, to study general identity construction.
Vårlamm eller dikoproduktion i Dalarna : fallstudie
This study investigates a farm in Dalarna which includes 16 ha of farmland and 1, 7 ha of
pasture. The purpose is to find out if it is possible to start an animal production in
Dalarna. The study is set only to compare spring lamb production with
nurse cow production.
There are two buildings on the farm that can be used for this purpose. One is an old
cowshed, and the other is an unused silo for silage with a roof on top. Both of the
buildings are compared to every alternative in the calculations.
Byggfel på plåttak : - Bristande kommunikation eller bara slarv?
The mistakes and failures on the roof are noticed during inspection of the construction, many of the commentaries are recurring. A contractor should only need to get a commentary once and then learn from the mistake. It has in this study been brought to light that the solution is not to tell the contractors to "stop slattern", it is more complicated than that. Today, the biggest problems are found in leadership, communication, feedback of experience and that the entrepreneurs take too little responsibility.To minimize the amount of commentaries all contractors need to work with a clearer leadership where the leader is both respected and appreciated. The leader must in an effective way be able to convey all the information to all employees.
Klimatpåverkan vid vägbyggnad -beroende av vald konstruktion
It?s a fact that the climate is affected by the vehicle that runs on the worlds roads. But theconstruction of the road itself is rarely thought of as a climate threat. Svevia and the Swedish roadadministration have opposite views of how the construction of roads should be carried thru. It?sthe difference between those two construction methods that is the base in our thesis.The amount of energy use or the emissions are not analyzed for neither the Swedish roadadministrations nor Svevias construction models.
Energi- och kostnadseffektiva klimatskal : För lager-, industri- och kontorsbyggnader
A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.
L?gkonjukturens p?verkan inom byggf?retag
The purpose of this study was to gain a better understanding of how medium-sized construction companies adapt and how they choose to reorganize their operations in relation to the recession. The study has as its theoretical starting point theories about organizational learning, the impact of the economy on construction companies and strategies for dealing with recessions. The
method used to conduct the study was semi-structured interviews with representatives from 15 different construction companies. The results of the study show that they used several strategies to adapt and reorganize the business in accordance with the recession. Some construction companies had to make cost savings as a result of the recession.
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.
Tillverkarnas syn på utvecklingen av väderskydd
How does the weather protection systems look like today, and how will they be developed in the future? These are questions that we have worked with during this project. At the start of our report there?s a summary of the leading weather protection manufacturers in Sweden. We have explained how these systems are constructed and how they work.
Värdering av anbud vid kommunala upphandlingar av byggprojekt
The thesis deals with evaluation of tenders for communal construction procurement. Each year the public procurement equals the value of millions of Swedish kronors, of which construction projects makes up a large proportion. These projects tend to often exceed their budgets. The aim with the thesis is to investigate if there are faults in the tender evaluation process. The theoretical framework for the study partly consists of a review on how the communal evaluation work is described in law and practice.
