Muligheter og utfordringer i veiprosjekter ved bruk av Best Value Procurement i kombinasjon med totalentreprise : En casestudie av Nye Veier prosjekt…
2018
Masteroppgave industriell økonomi og teknologiledelse IND590 - Universitetet i Agder 2018 Nye Veiers project E18 Rugtvedt-Dørdal is the first project in Norway to use the procurement method Best Value Procurement. The project is carried out as a Design-Build contract, which also is fairly new in the road construction industry. The purpose of this thesis is to reveal how Nye Veiers new project execution model has influenced the project execution phase, regarding cooperation, constructability and customer value. This will be discussed in the context of theories regarding transaction costs, the principal-agent problem, network in value chains and learning. The study is based on an abductive ap…
Overgangen fra utførelsesentreprise til totalentreprise for veiprosjekter : Virkninger på tid, kost og kvalitet. En casestudie av ny E18 Tvedestrand …
2018
Masteroppgave industriell økonomi og teknologiledelse IND590 - Universitetet i Agder 2018 Nye Veier ble opprettet våren 2015, på bakgrunn av Samferdselsdepartementets ønske om effektivisering av utbygging, drift og vedlikehold av riksveinettet. Nye Veier har som mål å være en slank byggherre organisasjon, som skal «bygge gode veier raskt og smart». Effektiv prosjektgjennomføring skal blant annet oppnås med bruk av totalentrepriser. Formålet med denne oppgaven er å belyse Problemstillingen: hva er virkningen av overgangen fra utførelsesentreprise til totalentreprise på samferdselsprosjekter, med hensyn til måloppnåelse. Oppgaven er skrevet som en casestudie, med E18 Tvedestrand – Arendal som…
Modularisering og koordinering mellom flere aktører i et innovasjonsprosjekt : modulbaserte marine løsninger for aktivitetsanlegg og gjestehavner
2014
Masteroppgave i industriell økonomi og teknologiledelse IND 590 Universitetet i Agder 2014 Prosjektet vi har tatt for oss skal i første rekke utvikle fysiske løsninger, prinsipper og produksjonsprosesser som raskt kan oversette kundekrav, arealmessige og naturgitte forutsetninger til bryggeløsninger og anlegg av høy kvalitet. Anlegg og løsninger skal være skalerbare slik at man i tillegg til store gjestebrygger/anlegg, som skal utvikles i samarbeid med Arendal Havn i dette OFU-prosjektet, også kan adressere for eksempel små private bryggeanlegg som marked. Fleksibiliteten og kundetilpasning muliggjøres ved en gjennomgående modularisering- og plattformtankegang. Prosjektet er sammensatt av i…

Master's thesis in Civil and structural engineering (BYG508)
Sustainability assessment of an apartment building containing reinforced concrete or cross-laminated timber (CLT)
2019
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2019 Today, the construction industry contributes to40% of the world’s energy consumption and greenhouse gasemissions(GHGs). According to theIntergovernmental Panel on Climate Change’s(IPCC)report, the greenhouse gas emissions must be reduced by 40-50 percent to limit Global Warmingto 1.5 degreesrather than 2 degreesby 2030. The United nation’s (UN)SustainabilityGoals are the world's common work plan to stop climate change by 2030. To achieve the above goals, it is crucial for the construction sectors to look forbetter,alternative construction materials as top concern to sustainability and environmental issues…
Transition to a fossil- and emission-free construction industry
2018
Master's thesis Industrial Economics and Technology Management IND590 - University of Agder 2018 The object for this thesis is to see how Nettpartner, which is Norway’s largest electrical infrastructure contractor, can contribute to the green change in the construction industry. To go green has become a big topic in the Norwegian construction industry during the last few years, and in 2017 a report concluded that the Norwegian construction industry could reduce their emissions of greenhouse gases with close to 99 % if the industry planned better before they started building. The method used in this research is the constructive research. The aim of constructive research is to solve practical…
Implementering av maskinsyn for montering av fasadeplater
2017
Masteroppgave i mekatronikk MAS500 - Universitetet i Agder 2017 The construction industry has seen a surge in efficiency and automation solutions in recent years. MacGregor, in cooperation with the University of Agder want to use crane and lifting technology to streamline construction processes. Facade panels are widely used due to ease of installation and require minimal maintenance. The process associated with installation has an automation potential. This thesis looks at the implementation of machine vision for installation of facade panels. Installation is done using a ABB IRB6600 industrial robot and a vacuum tool. The machine vision is based on OpenCV and C++. The main components of t…
Silica Green Stone as an SCM in concrete paving stones production : In order to reduce the total environmental footprint
2021
Master's thesis in Civil and structural engineering (BYG508) The cement industry is responsible for around 7% of the global CO2 emissions. Reducing this number has been on the forefront of the industry's mind for decades, but even with constant improvement and constant reduction in CO2 emissions per tonne cement used, the increasing globalization has kept the emissions high. Research in the industry has discovered supplementary cementitious materials (SCMs), that when partly replacing cement will produce most of the same results. SCMs are by-products from other industries and natural progression has led to the need for new ones. This thesis is, together with UiA, Aaltvedt Betong, SINTEF and…
Post weld heat treatment of welded low alloyed steel pipes : Use of AISI 4130 steel in hydrogen sulfide environment and its post weld heat treatment …
2019
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2019 Based on the results from pre-projectand workcovered by this thesis, no better alternatives to AISI 4130 material was found, neither could it be safely concluded for removal of NACE MR0175/ISO 15156 requirementsin any parts of high-pressure drilling fluid system. SinceAISI 4130 hasshown to be the optimal choice for the system,it was decided to look forimprovementsof welding procedure by optimization ofpost weld heat treatmentforthis steel.Heat treatment is an expansive and time-consuming procedure that,if not done correctly,could weaken the materialand jeopardize the safetyof the system.Inthis thesis, whi…
Mixed-valence polyoxometalate clusters. III. Vibronic problem for the 2-electron reduced heteropoly blue with the Keggin structure
1995
Abstract A general approach to the vibronic problem of delocalized electronic pairs in mixed-valence compounds is developed and applied to understand the ways of electron delocalization in dodecanuclear polyoxometalate clusters containing two moving electrons. The interplay between electronic and vibronic interactions is examined. The electronic spectrum is shown to consist of two spin triplets 3 T 1 and 3 T 2 and three spin singlets 1 A 1 , 1 E and 1 T 2 levels determined by the double-transfer processes (parameter P ). Jahn-Teller and pseudo-Jahn-Teller problems ( 3 T 1 + 3 T 2 ) ⊗ ( e + t 2 ) and ( 1 A 1 + 1 E + 1 T 2 ) ⊗ ( e + t 2 ) have been considered in the framework of the Piepho-Kr…
