Uppföljning av system för vägentreprenörer i skogen

Holmen Skog is one of the largest forestry companies in Scandinavia and they depend heavily on a large network of forest roads for production and logistics in connection to their forestry operations. The company recently introduced a new system for planning of road management. The system will also be developed with the intention to facilitate the monitoring of actions performed by road contractors. This report will provide information to support future decisions regarding further development of the system, after its introduction. In addition to a presentation of results from interviews, the report also provides a smaller study of the different subjects associated with roads, process work and process development. The study is largely based on interviews with road contractors that perform work for Holmen Skog today.

Stress i byggbranschen : Orsak till stress i byggbranschen samt förslag på åtgärder

Stress and burnout are two words that are commonly occurring in many contexts today. More and more people experience that they are stressed and that they does not feel well. The long term sick -leave increases as a consequence of people being burned out. These phenomena prolong over all ages, sexes, classes and professional categories, which probably means that the construction industry would not be spared.  In the construction industry, stress and bad health are no new phenomenon, already during the 1970s and big parts of the 1990 s, the construction sector were exposed to the phenomena.A sector that has a large turnover annually cannot presumably be faultless.

Att få tillträde till trädgården: Om konstruktionen av chefskap i coaching

During the last decade executive coaching has become an increasingly popular method of management development. Few studies have been conducted within this area, especially in Sweden, and little has been said about the construction of management in executive coaching. The purpose of this master?s thesis is to study executive coaching from a social constructionist perspective, focusing on the construction of management. The two research questions are: How is management constructed in executive coaching? How can we understand the construction of management in executive coaching? Additionally, we identify gender as a social construction of importance and thus include a gender perspective in our analysis.

Performativitet och bildkonst: eller hur apor verkar i världen

This essay examines the visual art of Helena Blomqvist with theory of performativity from Judith Butler among others, with a focus on the potential of visual art to question and dislocate norms. It consists of an analysis of three works of art from three aspects: the work of art, the viewer and the situation, and eventuates in an analysis of how the works relate to representation and norms. The construction of the works is related to Butler's theory of identity construction..

Skotares bränsleförbrukning :

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

Implementering av Virtuellt Byggande i byggprocessen : Fallstudie av NCC Construction Sverige AB

Virtual Design and Construction (VDC) is the definition for using BIM in the construction process to simulate and analyse the building. Resulting use of the technology will according to proponents lead to fewer construction errors, a better understanding between stakeholders for the construction project, less communication problems and a smoother construction process. Although BIM has according to researchers a big potential, few companies have succeeded in broad and continues implementation. The study aims to identify the factors affecting the implementation. More precisely identify what factors influencing the decision to adopt VDC and potential barriers in the diffusion process. The empirical findings are based on a case study of NCC Construction Sweden.

Effects of Driver, Vehicle, and Environment Characteristics on Collision Warning System Design

The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.

Flodpärlmusslans status i Laxtjärnbäcken : Effekter på flodpärlmusslan av sedimentbelastning och förekomst av bäckröding

The aim of this present study was to determine and evaluate whether the presence of brooktrout (Salvelinus fontinalis) and sediment load may be a threat against the reproduction anddistribution of freshwater pearl mussel (Margaritifera margaritifera) in a creek located innorthern Sweden. Freshwater pearl mussel is an endangered species and is dependent ofbrown trout (Salmo trutta) to reproduce. Therefore there are concerns of indirect effects onthe population of pearl mussel by competition between brown trout and brook trout. Ditchesfrom a nearby gravel road have been fixed to lower the sediment load into the creek. I tried toevaluate this action plan.

Ett kvalitativt arbete på väg : - En kvalitativ undersökning för att öka kunskapen gällande systematiskt arbetsmiljöarbete inom en organisation som arbetar med vägservice.

The purose of the study is to increase knowledge regarding systematic enviromentarl work in an organization that works with road services. Work on the road is done in a hazardous environment with constant danger regarding the life of the individual. The site of the work varies in accordance with where the needs ae . This requires skilled workers capable of working independently and that they are experienced din doing their own risk assessments in accordance with the individual believes that the situation calls for work to be performed safely. The study was conducted with a qualitative research approach in which four employees of different positions, knowledge, experience and vision to work in a hazardous environment were interviewed. The focus rests on the organization, management, and individual aspirations for a safe and secure working environment. The study adds weight to the relationship between the purchaser of the work and the organization as a prime contractor due to the compexity of the organization.

Byggnadsarbetarens syn på att bli involverad i projekteringen : En intervjustudie i byggprojekt

Title Becoming involved in the planning process - from the construction workers perspective.University/Institution Halmstad UniversityKeywordsEmpowerment through participation, construction workers involvement in decision making in the planning process, knowledge management and communication in the planning process, partnering, human resource managementAimThe aim of this bachelor thesis is to provide knowledge and examine how construction workers perceive involvement in the planning process of partnering projects, what they can contribute and what they get out of the planning process.Methodology The study was conducted with a qualitative approach in the form of semi-structured interviews.          The interview studie consist of 10 interviews with construction workers who are specially educated in participating in the planning process at the company ByggDialog AB.ConclusionAll respondents are positive to be involved in the planning process. The main advantages they can see is that they are able to influence technical solutions and methods that will be used later on in the production. Therefore it is important to consider when construction workers should be involved in the planning process so that they get the chance to influence in this decisions.When it comes to the decision making the construction workers should be involved in the decisions that are related to their tasks in the production such as technical solutions, choice of methods and materials. Their main duties and working hours should be in the production.Involvement in planning does not automatically mean that the construction workers are involved in the decision making, it is up to them how much they participate.

Konstruktion av efterbehandlare

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

Chefers identitet och identitetsskapande: en studie av chefer i offentlig verksamhet

The interviews were analyzed from a hermeneutic approach. The results showed that the managers´ experience of their identity and their construction of identity were full of nuances and was characterized by a being and a becoming. The managers had several social identities at their disposal, which were brought to the fore due to the situation.

En jämförelse avseende beståndsgående-och stickvägsgående gallringsmaskiner

The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted. The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages. The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent). Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated. Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same. However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time. If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..
