Ventilation on demand (VOD) concept has earned significant worldwide attention by several mining companies in recent years. It is a concept where airflow is provided only to areas that require ventilation. The implementation of the concept has resulted in significant savings in annual energy consumption and cost for several companies globally. The research presented in this thesis sought to present the VOD system as an alternative solution and strategy to improve the ventilation system of Konsuln mine. The system is expected to cope with a planned increase in production rate and meet requirements in the new Swedish Occupational Health & Safety (OH&S) regulations, Arbetsmiljöverkets förtfattningssamling (AFS) 2018:1, which is based on the EU directive 2017/164 where Threshold Limit Value (TLV) for gases have been significantly reduced and provide safe work environment for workers in the mine. The thesis work started with planning and execution of a PQ (Pressure – Quantity) survey to calibrate the existing ventilation model of Konsuln mine. This was to ensure that the model is reasonably accurate to give reliable simulation predictions of the performance of Konsuln ventilation system in its current state and for the future. The good correlation between the modelled and underground measured values validated the model for further ventilation planning. The study further investigated and analyzed the current and future ventilation demand of LKAB test mine, Konsuln, to design a VOD system for its operations.The work outlined three main VOD design scenarios I, II, and III based on the proposed production plan, schedule, and the mining process that present the underground working conditions on the three main levels (436, 486 and 536) of Konsuln mine. Diesel, battery-powered, heat, and blast simulations were carried out for all the scenarios in the calibrated ventilation model using VentSim Design simulation software. The model was again used to estimate the annual ventilation power cost for the VOD scenarios to highlight the benefit and cost savings advantage under the VOD design system to deliver enough airflow quantity compared to the conventional system of ventilation. Simulation results showed that about 15.6% – 49.1% and 76.4% - 86.7% of significant cost savings will be achieved for diesel and battery-powered machineries respectively, while still supplying the needed amount of air to working areas to keep contaminants below their Threshold Limit Value -Time Weighted Average (TLV-TWA) and provide a good working environment. For additional benefits and savings of the Ventilation on Demand (VOD) system implementation, some considerations for equipment, personnel positioning and identification, monitoring system, and stations have also been discussed in this work.  These include; (i) Utilization of LKAB’s database system, Giron, in addition to mounting tags with unique IDs on machineries, to track the route of LHDs and trucks to deal with the challenge of airflow supply shortfall associated with auxiliary fans adjustment to affect target locations. (ii) Installation of temperature sensors, flow meters, gases and Diesel Particulate Matter (DPM) monitoring systems at specific, appropriate, and optimal locations in the mine for efficient implementation of the VOD system strategy. The heat simulations for both diesel and battery-powered machineries were carried out for the month of July when the highest temperatures in Kiruna are often recorded for the summer. They predicted the highest temperatures in working areas to be well below the limit used in Australia, 28°C Wet Bulb (WB). Four scenarios A, B, C and D were also considered for blast clearance time simulation using both the ramp and exhaust shaft. The blast simulation results indicated that the time to dilute and clear blast fumes through the exhaust shaft saves some clearance time compared to exhaustion through the ramp, although the shaft exhaustion will require additional financial commitment to purchase and install exhaust fans on each of the three main levels of the mine. Nevertheless, major ventilation work and practices such as removal of regulator in front of primary fans, additional radon measurement, and good auxiliary ventilation practices have been recommended to improve and actualize the benefits outlined in this work.

De nombreuses études concluent que la charge mécanique supportée par le genou, qu’elle soit reliée à l’obésité, aux sports intenses, à une altération biomécanique des structures de l’articulation ou à une exposition à des charges lourdes durant les activités occupationnelles, est considérée comme un facteur de risque important au développement de la gonarthrose. La gonarthrose reliée au travail a été le sujet de nombreuses études et plusieurs d’entre elles ont rapporté une prévalence accrue de la gonarthrose chez les travailleurs de certains domaines en particulier, comme la construction, la pose de plancher, la peinture, l’exploitation minière, l’agriculture et le travail en atelier et en milieu de la santé. Les personnes qui travaillent dans ces métiers sont exposées à des positions ou des activités nuisibles, comme travailler à genoux ou accroupi, monter des escaliers ou des échelles, transporter des changes lourdes et marcher de façon prolongée. Ces gestes surchargent l’articulation du genou, ce qui cause des modifications aux structures de l’articulation du genou ou aux adaptations neuromusculaires de patron de mouvement du genou. Ces modifications structurelles et adaptations neuromusculaires peuvent apporter des changements cinématiques à la marche qui peuvent initier la gonarthrose ou contribuer à sa progression. L’objectif principal de la présente étude était d’analyser l’effet d’une surcharge mécanique sur l’articulation fémoro-tibiale (AF-T) subie au travail lors d’une tâche de marche et comparer le patron cinématique de l’articulation fémoro-tibiale des travailleurs exposés à une surcharge mécanique à celui des travailleurs non exposés. Vingt-quatre travailleurs exposés à une surcharge mécanique et neuf travailleurs non exposés ont participé à l’étude. Les données cinématiques de la marche ont été enregistrées au niveau du genou dans des conditions cliniques en utilisant un système de suivi du mouvement électromagnétique. Les paramètres suivant ont été extraits et utilisés pour la comparaison des groupes : l’angle maximum lors du contact initial, l’angle ii maximum de flexion durant la réponse à la charge, l’angle minimum au moment de l’appui unipodal et l’étendue max-min du cycle. La comparaison des groupes pour les variables cliniques et cinématiques a été effectué par l’utilisation de tests-t bilatéraux (« Student-t tests ») et de tests ANCOVA utilisant le poids et la vitesse comme covariables. Les travailleurs exposés à une surcharge mécanique présentaient un plus grand angle de flexion de l’articulation fémoro-tibiale au contact initial, durant la réponse au chargement et à la phase unipodale et ils ont démontré une étendue d’angle moindre que les travailleurs non exposés. Nous croyons que les données cinématiques de la marche peuvent donner des idées sur les facteurs biomécaniques qui pourraient prédisposer les travailleurs au développement ou à la progression de la gonarthrose. Une meilleure compréhension de ces facteurs pourrait être un premier pas vers le développement d’une intervention plus efficace pour cette population. / Many studies agree that mechanical knee loading, either related to obesity, intense sports, biomechanical alteration of the knee or exposition to heavy load occupational activities, is an important factor in knee OA development. Work related knee OA has been the focus of numerous studies, many of them reporting increased knee OA prevalence in workers involved in particular occupational fields such as construction, floor layer, painting, mining, agriculture, shop assistant and health care employees. Persons working in these occupations are exposed to noxious positions or activities such as kneeling, squatting, climbing stairs or ladders, carrying heavy load and prolonged walking. These gestures overload the knee joint, resulting in modifications of the knee joint structures or in neuromuscular adaptations of the knee movement pattern. These structural modifications and neuromuscular adaptations can bring about gait kinematic changes that can either initiate knee OA or contribute to its progression. The main objective of this study was to analyze the effect of mechanical overloading on the tibial-femoral joint suffered during walking tasks at work and compare the kinematics gait tibial femoral joint of workers exposed to knee overloading (KO workers) to that of non-knee overloaded workers (non-KO workers). Twenty four KO workers and 9 non-KO workers participated to the study. Gait kinematic data were recorded at the knee in a clinical setting using an electromagnetic motion tracking system. The following parameters were extracted and used for group comparison: knee angle at initial contact, peak knee flexion angle during loading response and angle range. Group comparison for clinical and kinematic variables of interest was performed with Student-t and ANCOVA tests. KO workers had greater knee flexion angle at initial contact, during loading response and single limb support, and they demonstrated a lower angle range than non-KO workers. iv We believe that gait kinematic data can suggest biomechanical factors that could predispose workers to the development or progression of knee OA. A better understanding of these factors could be a first step toward more efficient intervention within the population.

Background: Swedish law demands a systematic work environment management system (SWEM) and establishes the employer as responsible for this. In 2016, 44 % of Swedish Work Environment Authorities’ submissions regarded lack of SWEM. The law defines occupational health and safety services (OHSS) as an objective part with expert knowledge within the fields of work environment and rehabilitation. Aim of the study: The purpose of this study is to investigate how OHS engineers employed in OHSSs assist customer enterprises in the work of developing and maintaining OHS management systems. The study further aims to identify resources, factors of success, necessary skills and other factors that facilitate this work. Method: Six semi-structured interviews were conducted with OHS engineers employed in one of the top five largest OHSS companies in Sweden. Result and analyses: Respondents were found to apply similar methods in supporting clients’ OHSM although working in different regional branches and no nationwide training program exists. In working with OHSM support the OHS engineers mainly used self-produced, flexible tools along with external checklists and templates. Dialogue, an active involvement of the client in developing the OHSMS, internal motivation of the company and experience and competence of the OHS engineer was described as the most essential factors of success. Conclusions: Our study shows that the OHS engineers interviewed to a large extent work with OHSM support in a way that is consistent with what is found in other studies to be a successful way of collaborating with client companies. Areas of improvement for the OHSS company include deepening relations with clients, contracts better supporting collaboration and procedures for spotting client’s OHSM shortcomings earlier.There is a challenge to find a balance between giving OHS engineers freedom in choosing how they work, providing clients flexible solutions and assuring that certain standards of service are met.We identify the need of a mentorship program for OHS engineers within the OHSS company that would include tutoring both in OHS interventions and the consultant role.Finally, OHS engineers may need to develop their skills in OHS related business economy and how to integrate OHS interventions with the business strategies of the client companies. / Bakgrund: Svensk lagstiftning kräver att arbetsgivare arbetar med systematiskt arbetsmiljöarbete (SAM). Under 2016 ledde 44 % av Arbetsmiljöverkets inspektioner till anmärkningar på grund av brister i SAM. Lagen definierar företagshälsovård (FHV) som en objektiv part med expertkunskap inom arbetsmiljö och rehabilitering. Syfte: Syftet med studien är att undersöka hur arbetsmiljöingenjörer inom FHV hjälper kundföretag med arbetet att utveckla och underhålla ledningssystem för arbetsmiljö. Studien syftar också till att identifiera resurser, framgångsfaktorer, nödvändig kompetens samt andra faktorer som främjar arbetet med SAM. Metod: Sex semi-strukturerade intervjuer utfördes med arbetsmiljöingenjörer anställda i ett av Sveriges fem största företag inom företagshälsovård. Resultat och analys: Respondenterna använde liknande arbetssätt i arbetet med att stötta kunders SAM. Detta trots att de arbetade i olika regioner inom företaget samt avsaknad av nationella riktlinjer. I arbetet med SAM använde arbetsmiljöingenjörerna framförallt egenproducerade, flexibla verktyg samt externa checklistor och mallar. Dialog, aktiv deltagande av kund under utveckling av SAM, intern motivation hos kundföretaget samt erfarenhet och kompetens hos arbetsmiljöingenjören beskrevs som de viktigaste framgångsfaktorerna. Slutsatser: Studien visar att de intervjuade arbetsmiljöingenjörernas arbete med SAM i stor utsträckning överensstämmer med vad andra studier funnit vara ett framgångsrikt samarbete med kundföretag. Förbättringsområden för FHV-företaget inkluderar fördjupande av kundrelationer, kontrakt som bättre stödjer sådant samarbete och rutiner för att upptäcka brister i SAM tidigare.En utmaning är att hitta en lämplig balans mellan arbetsmiljöingenjörens behov av fritt arbetssätt, erbjuda kunden flexibla lösningar och samtidigt säkerställa en likartad service inom företaget.Behov av ett mentorprogram, som inkluderar handledning inom både arbetsmiljöarbete och konsultrollen, för arbetsmiljöingenjörer inom FHV-företaget identifierades.Slutligen kan arbetsmiljöingenjörer behöva utveckla kompetens inom arbetsmiljöekonomi samt hur arbetsmiljöarbetet kan integreras med affärsstrategier inom kundföretagen.

La répétition d’efforts de faible intensité provoque de la fatigue musculaire et représente un facteur de risque de développement des troubles musculosquelettiques (TMS) à l’épaule. La détection de la fatigue musculaire permettrait de meilleures interventions de prévention de TMS liés au travail répétitif. L’objectif de ce mémoire est de développer de nouveaux indicateurs permettant d’évaluer le mouvement des travailleurs à l’aide de capteurs inertiels portatifs afin d’offrir un outil d’évaluation du niveau de fatigue employable sur le terrain. Pour ce faire, vingt-quatre travailleurs ont réalisé une tâche de travail avant et après une tâche de pointage répétitif (RPT) générant de la fatigue musculaire. La fatigue était évaluée à l’aide de l'échelle CR10 de Borg toutes les 30s et d’une contraction maximale réalisée toutes les 2 minutes. Des données de capteurs inertiels, positionnés sur le tronc et les membres supérieurs des travailleurs, ont été analysées en temps-fréquence et leur coordination inter-segment calculée afin d’extraire des indicateurs de fatigue. Les résultats montrent une augmentation du spectre de puissance et de la variabilité de la coordination sur les segments proximaux du haut du corps (tête, sternum, bassin, épaule, bras, avant-bras et main) pendant la RPT. Aussi, une augmentation du spectre de puissance moyen a été observée sur les segments du bras (main, avant-bras et bras supérieur) pendant la tâche de travail réalisée immédiatement après la RPT. En conclusion, il semblerait possible, en observant de tels changements cinématiques, de détecter la fatigue musculaire des travailleurs en industrie à l’aide de capteurs inertiels. / The repetition of low-intensity efforts causes muscle fatigue and represents a risk factor for the development of musculoskeletal disorders (MSD) in the shoulder. The detection of muscle fatigue would allow for better interventions to prevent MSDs related to repetitive work. The objective of this dissertation is to develop new indicators to evaluate the movement of workers using portable inertial sensors to provide a tool for evaluating the level of fatigue that can be used in the field. To do this, twenty-four workers performed a work task before and after a repetitive pointing task (RPT) generating muscle fatigue. Fatigue was assessed using the Borg CR10 scale every 30s and a maximal contraction performed every 2 minutes. Data from inertial sensors, positioned on the trunk and upper limbs of the workers, were analyzed in time-frequency and their inter-segment coordination calculated to extract indicators of fatigue. The results show an increase in the power spectrum and coordination variability on the proximal upper body segments (head, sternum, pelvis, shoulder, arm, forearm and hand) during RPT. Also, an increase in the average power spectrum was observed over the arm segments (hand, forearm, and upper arm) during the work task performed immediately after RPT. In conclusion, it would seem possible, by observing such changes in kinematics, to detect muscle fatigue in industrial workers using inertial sensors.

Hybridarbete har medfört fördelar och utmaningar som arbetsgivare behöver uppmärksamma för att främja ett hälsosamt arbete. En hybrid arbetsform kan bidra med det bästa från två världar, distans- och kontorsarbete, förutsatt att arbetsgivare och arbetstagare samverkar för att utveckla nya färdigheter för att anpassa sig till det nya arbetssättet. Denna studie syftar till att skapa en djupare förståelse för den organisatoriska och sociala arbetsmiljön vid hybridarbete. Studien är genomförd med en kvalitativ ansats och materialet har samlats in med hjälp av tio semistrukturerade intervjuer med både medarbetare och chefer inom en svensk offentlig organisation. Studiens metodval är inspirerad av empirisk fenomenologi med ett hermeneutiskt förhållningssätt som syftar till att skapa förståelse. Empirin har tematiserats och analyserats med hjälp av tematisk analys. Studiens resultat visar att den främsta fördelen med hybridarbete är flexibiliteten till att påverka balansen mellan arbete och fritid. Till följd av den hybrida arbetsformen visar resultatet utmaningar i egenskap av minskade fysiska interaktioner med kollegor, digital trötthet, uteblivna pauser samt svårigheter med gränsdragningen mellan arbete och fritid. Resultatet visar att tydliga riktlinjer för hybridarbete får betydelse för hur individen upplever den organisatoriska och sociala arbetsmiljön. Studien konstaterar att tillgång till socialt stöd, delaktighet, dialog, autonomi samt explicita riktlinjer och rutiner som kan anpassas efter individuella behov främjar en god arbetsmiljö. Avslutningsvis presenteras en modell som kan användas av praktikersamhället för att bidra med kunskap om hur känslan av sammanhang (KASAM) främjas i den hybrida arbetsmodellen. / Hybrid work has brought benefits and challenges that employers must observe to promote healthy work among employees. Hybrid working can create the best of both worlds, remote and office work, if employers and workers work together to develop new skills to adapt to the new way of working. This study aims to create a deeper understanding of the organizational and social work environment in hybrid work. The study is conducted with a qualitative approach and the material has been collected using ten semi-structured interviews with employees and managers within a Swedish public organization. The study's choice of method is inspired by empirical phenomenology with a subjective hermeneutic approach that aims to create understanding. The empiricism has been thematized and analyzed using thematic analysis.The results of the study show that the main advantage of hybrid work is increased flexibility regarding the ability to influence the balance between work and leisure. The results also show some possible disadvantages of the hybrid working form, such as reduced physical interactions with colleagues, digital fatigue, missed breaks and difficulties with drawing the line between working time and free time. The results shows that clear guidelines for hybrid work are important for how the individual experiences the organizational and social work environment. The study states that access to social support, participation, dialogue, autonomy and explicit guidelines and routines that can be adapted to individual needs promote a good work environment. Finally, a model is presented that can be used by the practitioner community to contribute knowledge about how the sense of coherence (SOC) is promoted in the hybrid work model.

Cette thèse vise à répondre à trois questions fondamentales: 1) La diminution de l’excitabilité corticospinale et le manque d’inhibition intracorticale observés suite à la stimulation magnétique transcrânienne (SMT) du cortex moteur de la main atteinte de sujets hémiparétiques sont-ils aussi présents suite à la SMT du cortex moteur de la jambe atteinte? 2) Est-ce que les altérations dans l’excitabilité corticomotrice sont corrélées aux déficits et incapacités motrices des personnes ayant subi un accident vasculaire cérébral depuis plus de 6 mois? 3) La vibration musculaire, étant la source d’une forte afférence sensorielle, peut-elle moduler l’excitabilité corticomotrice et améliorer la performance motrice de ces personnes? Premièrement, afin d’appuyer notre choix d’intervention et d’évaluer le potentiel de la vibration mécanique locale pour favoriser la réadaptation des personnes ayant une atteinte neurologique, nous avons réalisé une révision en profondeur de ses applications et intérêts cliniques à partir d’informations trouvées dans la littérature scientifique (article 1). La quantité importante d’information sur les effets physiologiques de la vibration contraste avec la pauvreté des études qui ont évalué son effet thérapeutique. Nous avons trouvé que, malgré le manque d’études, les résultats sur son utilisation sont encourageants et positifs et aucun effet adverse n’a été rapporté. Dans les trois autres articles qui composent cette thèse, l’excitabilité des circuits corticospinaux et intracorticaux a été étudiée chez 27 sujets hémiparétiques et 20 sujets sains sans atteintes neurologiques. Les fonctions sensorimotrices ont aussi été évaluées par des tests cliniques valides et fidèles. Tel qu’observé à la main chez les sujets hémiparétiques, nous avons trouvé, par rapport aux sujets sains, une diminution de l’excitabilité corticospinale ainsi qu’un manque d’inhibition intracorticale suite à la SMT du cortex moteur de la jambe atteinte (article 2). Les sujets hémiparétiques ont également montré un manque de focus de la commande motrice lors de l’activation volontaire des fléchisseurs plantaires. Ceci était caractérisé par une augmentation de l’excitabilité nerveuse des muscles agonistes, mais aussi généralisée aux synergistes et même aux antagonistes. De plus, ces altérations ont été corrélées aux déficits moteurs au membre parétique. Le but principal de cette thèse était de tester les effets potentiels de la vibration des muscles de la main (article 3) et de la cuisse (article 4) sur les mécanismes neuronaux qui contrôlent ces muscles. Nous avons trouvé que la vibration augmente l’amplitude de la réponse motrice des muscles vibrés, même chez des personnes n’ayant pas de réponse motrice au repos ou lors d’une contraction volontaire. La vibration a également diminué l’inhibition intracorticale enregistrée au quadriceps parétique (muscle vibré). La diminution n’a cependant pas été significative au niveau de la main. Finalement, lors d’un devis d’investigation croisé, la vibration de la main ou de la jambe parétique a résulté en une amélioration spécifique de la dextérité manuelle ou de la coordination de la jambe, respectivement. Au membre inférieur, la vibration du quadriceps a également diminuée la spasticité des patients. Les résultats obtenus dans cette thèse sont très prometteurs pour la rééducation de la personne hémiparétique car avec une seule séance de vibration, nous avons obtenu des améliorations neurophysiologiques et cliniques. / This thesis aims to answer three basic questions: 1) Are the decrease in corticospinal excitability and the lack of intracortical inhibition observed following transcranial magnetic stimulation (TMS) of the affected hand motor cortex of stroke patients present after TMS of the affected leg motor cortex? 2) Are the alterations in corticomotor excitability correlated with motor impairments and disabilities of subjects who have suffered a stroke for over six months? 3) Can muscle vibration, as a source of strong sensory afference modulate corticomotor excitability and improve motor performance of these subjects? First of all, to support our choice of intervention and to assess the potential of local mechanical vibration to promote the recovery of persons with neurological impairment, we conducted a thorough review of its physiological effects and clinical applications in the scientific literature (article 1). The wealth of information on the physiological effects of vibration contrasts with the lack of studies that have evaluated its therapeutic effects. Nevertheless, we found that, despite the paucity of studies, the results on its clinical use are encouraging and positive and no adverse effects were reported. In the other three articles included in this thesis, the excitability of corticospinal and intracortical circuits has been studied in 27 hemiparetic patients and in 20 healthy subjects without neurological disease or injury. Sensorimotor functions were also evaluated with valid and reliable clinical tests. Similar to that observed in the hand of hemiparetic patients, we found, compared to the healthy subjects, a decrease of corticospinal excitability and a lack of intracortical inhibition following TMS of the affected leg motor cortex (Article 2). The hemiparetic patients also showed a lack of focus of the motor output during voluntary activation of plantar flexors. This was characterized by an increase in the neural excitability not only of the agonist muscles, but also of the synergists and even the antagonist muscles. The main goal of this thesis was to test the potential effects of vibrating hand (Article 3) and thigh (Article 4) muscles on the neural mechanisms that control these muscles. We found that vibration increases the amplitude of motor responses in the vibrated muscles and even produces a response in subjects with no motor response at rest or during a voluntary contraction. The vibration also decreased the intracortical inhibition recorded in the paretic quadriceps muscle (vibrated muscle). The decrease was however not significant at the hand. Finally, using a cross-over design study, the vibration of the paretic hand or leg resulted in specific improvements in hand dexterity or leg coordination, respectively. In the lower limb, quadriceps vibration also reduced the spasticity in patients. The results obtained in this thesis are very promising for stroke rehabilitation because with a single session of vibration, we obtained neurophysiological and clinical improvements.

Health and safety during construction remains a worldwide challenge that the construction industry is facing. The German construction industry recorded an average of 110,000 accidents per year in the period of 2010 to 2019. A discernible trend toward a decrease in occupational accidents is not visible. In this context, traditional safety planning does not seem to be able to guarantee sufficient health and safety during construction. In line with the BIM Roadmap published by the German Ministry of Transport in 2015, it can be recognized that Building Information Modeling (BIM) is supposed to be increasingly used in upcoming years. This paper aims to identify how BIM could positively impact Occupational Health and Safety (OHS) during construction. Therefore, a thesis procedure, combining quantitative and qualitative research with an in depth literature review is introduced. This study reveals a high added value of using BIM for (1) safety rule checking and design validation and (2) safety education, training and communication. BIM as a decision supporting tool has the potential to reduce the underestimation of safety hazards and improve safety reporting, which have been identified as current vulnerabilities in the construction industry. Furthermore, an added benefit to sustainability following the concept of Construction Hazard Prevention through Design (CHPtD) is illustrated. In practice, however, BIM for OSH remains unused, while those working with BIM are not familiar with safety planning. This study indicates that in order to fully utilize the potential of BIM, intuitiveness and standardization is required, while those implementing BIM and those using BIM need to be aware of and willing to exploit the potential of new technologies. The challenge now is to recognize the potential of BIM in relation to OHS and to actively use BIM for health and safety purposes. / Att skapa en säker arbetsmiljö på byggarbetsplatsen är fortfarande en global utmaning för byggbranschen. I den tyska byggbranschen inträffade till exempel i genomsnitt 110 000 olyckor per år under perioden 2010-2019 och det syns ingen märkbar minskning. I detta sammanhang verkar traditionell säkerhetsplanering inte kunna garantera tillräcklig hälsa och säkerhet under byggandet. I samband med den strategiska BIM-implementeringsplanen som publicerades av det tyska transportministeriet 2015 ska Building Information Modeling (BIM) användas i allt större utsträckning under de kommande åren. Syftet med den här artikeln är att identifiera hur BIM skulle kunna ha en positiv inverkan på arbetsmiljö och säkerhet (OHS) på byggarbetsplatsen. Studien kombinerar kvantitativ och kvalitativ forskning med en djupgående litteraturgenomgång. Resultatet visar att det finns ett stort mervärde i att använda BIM för (1) kontroll av säkerhetsregler och validering av konstruktionen och (2) utbildning, träning och kommunikation om säkerhet. BIM som beslutsstöd kan möjliggöra en mer realistisk bedömning av säkerhetsrisker och förbättra säkerhetsrapporteringen, vilket har identifierats som aktuella sårbarheter i byggbranschen. Det finns också fördelar med att implementera konceptet Construction Hazard Prevention through Design (CHPtD). I praktiken är dock BIM för arbetsmiljöfrågor fortfarande oanvänd, samtidigt som de som arbetar med BIM inte är tillräckligt bekanta med säkerhetsaspekter. För att BIM:s potential ska kunna utnyttjas fullt ut krävs en ökad användarvänlighet och standardisering av verktygen. Samtidigt måste de som implementerar och använder BIM vara medvetna om och villiga att utnyttja den nya teknikens potential. Utmaningen är nu att förstå potentialen av BIM för arbetsmiljöaspekter och att proaktivt använda BIM för att öka säkerheten på byggarbetsplatser.
