It’s been known that checking of construction documents has become worse over time. There’s a lot to get done in a very short period of time and many therefore choose to do a sloppy checking or no checking at all. Checking of construction documents is done to ensure quality. Checking include both strength, building technics and technical drawing. External checking was the standard over 20 years ag
Environmental certification for buildings has become more common since the first certification system became available on the market in the 90s. Today there are hundreds of thousands buildings with an environmental certification. More and more companies choose to place their business in a certified building. The problem when companies are in the election of a new facility may be the lack of knowle
This study concerns materials logistics in the construction processes of complex building projects in urban developing areas, where the authors have carried out a case study on the future urban renewal project Oceanpiren, H+. Urban renewable projects can be regarded as a common category in construction, due to increasing urbanization followed by an enhanced demand. This type of project is often re
With today's sustainability thinking and environmental awareness, it is more important than ever to customize even our railway, with its components, for tomorrow's needs. An investment in the replacement of light source is not only an environmental and economic benefit, but also a win for the maintenance. We have chosen in this thesis to investigate why LED technology is not yet incorporat
The part of a structure which separates two floors is called a slab. A type of concrete slab that is becoming increasingly popular is hollow core slabs. A hollow core slab consists of slabs of 1,2 m width placed next to each other, and the space that is created between the slabs is filled with concrete after mounting. The hollow core slab transfers horizontal forces, such as wind load and earth pr
Abstract: In 2011 Vinnova funded a joint project between Nordkalk AB, Kalkproduktion Storugns AB (KPAB) and the department of Geology at the University of Lund. The goal of the project is to increase the general knowledge of limestone and in extension, facilitate for the industry. This thesis is a part of the project and consists of two separate parts which look into the geochemistry and thermal p
To ease railway traffic between countries in Europe, EU have decided that a new common signalling system should be implemented. This new signalling system is ERTMS, which is a shortening for European Rail Traffic Management System. Beside to ease traffic between countries, ERTMS can improve the level of safety and increase capacity on the railway network. The implementation of ERTMS amount a major
Pavements on bus stops is a complex subject because of the different forces that occur. Cement Stabilized asphalt is therefore used on the bus stops and has been so for about 16 years in Malmö to combine the best qualities of cement and asphalt which is bearing capacity and flexibility. In 2014 a formula was developed to calculate the breakdown of the pavement of bus stops by two students at Lunds
This bachelor thesis endeavors to promote a sustainable development and sustainable construction in Sweden. The purpose is to investigate the possibilities for a supplement to the environmentally certificate of a building, as a concept focused on environmentally conscious choices of building products and materials, based on a strategy named BATNEEC. This is analyzed by responding to six questions
Many construction companies have a construction service department but it is normally never the largest part of the company. Rather, the building services department has been seen as a fender to keep employees engaged when the economy’s been bad, with the result that no large investments have been put towards the service department. The logistics of the construction services business is different
This thesis is about BIM (Building Information Model/Modelling) and answer from The Railroad Industries point of view the questions asked in the report. There are different perceptions in the industry about what BIM means and what it is. This thesis will try to clarify the meaning of the concept BIM. Further on the thesis examines to which extent and how BIM is used in the railroad industry where
This study explores the analytical and conceptual closures within political economy and degrowth literature. In order to explore these closures, poststructural theories of postcolonial and queer have been used. Derridian deconstruction has been applied to the degrowth literature to illuminate the silences and contradictions present within the texts. A deconstructive reading of the degrowth literat
We live in a time where there is an increasing focus on the environment, in terms of classification of vehicle emission standards and environmental zones. Along with this and the fierce market competition that exists, it is odd that a greater effort has not been made in making material-transport more effective by renewing the tarmac on our road-network. The purpose of this report is to show the sa
The coastal city of Kalmar is known as an attractive summer destination, both locally and internationally. The coast has long been included as one of the municipality’s priority goals. In its city development vision, the municipality strives to utilize the coast and take it into consideration in urban planning. On the other hand, Kalmar has a historic character, which is visible through its urban
One problem with the Swedish railways is the low reliability and punctuality. A distinction can be made between major and minor disorders, where minor disorders have a greater impact on overall punctuality because of its large numbers. One way to describe the large disorders are with punctuality dips and punctuality depressions, which are short-term and long-term variations in punctuality. This st
By initiative from Sweco Rail, we have made a comparison between fixed and automatic tensioning devices for tramways to determine when there is an advantage to choosing an automatic device instead of a fixed solution. Main focus has been tramways in city environment, with extra focus on Gothenburg. The report attempts to answer the following questions: • When should the choice be an automatic tens
Lund Municipality, just like many other municipalities, has recurring problems with rutting at their bus stops. There is a notable problem in Lund though and the rutting occurs regardless of whether the stops are placed at high, medium or low-volume roads. In this thesis, eleven of the most vulnerable coatings in Lund Municipality were investigated. This thesis is written in collaboration with roa
This thesis is a study of the possibilities of introducing freight trams on tram networks in cities and to examine the possibilities in Helsingborg as a concrete example. The city of Helsingborg has plans to in the next ten years start the building of a new tram network in the city, a measure implemented to increase the capacity of the public transport system and to improve the environment in the
The average age of the signalling systems the Swedish railways is high and the technology old. Parts of the current system are over 50 years old and requires a high amount of service due to its old age. Due to an EU-directive regarding interoperability, the current signalling system on the most heavily trafficked parts of the Swedish railway (equal to about 2/3 of the total number of signalling po
