Comparison of Different Construction Methods for Multi‐Storey Timber Buildings
2018
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2018 In this master thesis, different timber materials and construction methods are examined concern‐ing the application in multi‐storey timber buildings. Although wood as a construction material has many advantages, it is today only used very little for larger constructions, concrete and steel dominate the building industry. Planners and engi‐neers are often lacking necessary expertise to utilise timber in a modern, effective way. In order to promote the development of modern, efficient multi‐storey timber buildings, the goal of this master thesis is to contribute to a better understanding of the wood’s chara…

En studie av fagarbeiderens informasjonsbehov på byggeplass : En kvalitativ casestudie
2018
Masteroppgave industriell økonomi og teknologiledelse IND590 - Universitetet i Agder 2018 Kontekst: Veidekke Agder bygger videregående skole i Tvedestrand, hvor det er gjort innkjøp av digitale verktøy som kan formidle informasjon til og fra fagarbeideren. Oppgaven omhandler gjennomføringen av en casestudie med utgangspunkt i lean-filosofi. Hensikten er at forutsetningene rundt skal effektiviseres og ikke fagarbeideren. Forskeren ønsker derfor å se hvordan fagarbeideren kan få sitt informasjonsbehov dekket, samtidig som at informasjonen ikke møter hindringer til og fra fagarbeideren. Metode: Det er blitt utført en kvalitativ casestudie, hvor data er blitt hentet gjennom Veidekke sine aktøre…
Integrated project delivery (IPD) in Norwegian construction projects : Sharing of risk and opportunities aiming at better cooperation and project ach…
2018
Master's thesis Industrial Economics and Technology Management IND590 - University of Agder 2018 In the architecture, engineering and construction (AEC) industry projects are often temporary in nature and are often characterised as PBO project-based organisations. Each project chooses a number of strategies which makes up a project development model. Traditionally models have focused on transactional contracting between actors in the value chain which opens up the way, for sub-optimisation and risk aversion as the common challenges. In such circumstances, each actor has a different perception of the aim and the success of the project, and so try to find ways to take the lowest risk and gain…
An evaluation of VDC in road maintenance projects -The professionals view on the benefits and barriers of VDC in road maintenance
2018
Master's thesis Industrial Economics and Technology Management IND590 - University of Agder 2018 Purpose: Give an overview of VDC in relation to road maintenance projects and make it easier for companies to decide if VDC is worth investing in. Goal: 1) To find out if there are any differences in the definition and understanding of VDC in the Norwegian market, compared to the definition provided by the CIFE (Center for Integrated Facility Engineering at Stanford University). 2) To identify frequent problems in road maintenance that VDC could solve. 3) To identify the obstacles standing in the way of the use of VDC in road maintenance and to figure out why it has not been adopted in road main…
Design av en offshore gangbru i fiberarmert polymer
2018
Masteroppgave bygg BYG508 - Universitetet i Agder 2018 Innovation and development are essential for a market in demand of faster, lighter and stronger solutions. As a material with high strength to weight ratio, and good possibilities of being premade, fiber reinforced polymers can meet those requirements. However, it has yet to challenge concrete, steel and aluminum as a structural material. This is the underlying challenge for the problem statement of this assignment, to construct an offshore gangway using fiber reinforced polymers. The design concept is based on existing steel and aluminum constructions within the size range of 25- 30m fully extended. To solve the problem and answer the …
The influence of steel fibres on compressive and tensile strength of ultra high performance concrete : A review
2020
Abstract This review paper presents the effects of steel fibre reinforcement regarding the compressive and tensile strength of UHPC. The intention is to give an overview of the research field and supply guidance for future research. Relevant papers were identified through a systematic literature search. An accumulation of the results shows that fibres have potential for improving the tensile strength of UHPC. The effect depends on fibre content, type and hybrid combinations. The effect of fibres on compressive strength seems to be questionable. Variations in test specimen geometry and other factors might also influence the results.
Graphene and graphene oxide on Ir(111) are transparent to wetting but not to icing
2021
Anti-icing coatings reduce the freezing onset temperature for water by changing the chemical and physical environment at the water-substrate interface to prevent ice nucleation and growth. Graphene oxide has several attributes that make it attractive as an anti-icing coating and it has been theoretically predicted that graphene oxide has a lower freezing onset temperature than pristine graphene. Here, we test this hypothesis using carefully prepared, well-characterized graphene oxide substrates. We compare the water contact angle for graphene and graphene oxide coatings, both prepared on iridium(111) surfaces. The results show both materials to be transparent to wetting, but indicate a lowe…
From Waste to Resource – Utilising Residue from Ready-Made Concrete as New Aggregate
2021
Abstract A new admixture is available, to reduce the sludge produced from the cleansing of production and transportation equipment in the fresh concrete industry. The result is agglomerations of hardening concrete, that might be utilised for aggregate. Utilisation depends on adequate properties. This paper reports from investigations on the physical and mechanical properties of the aggregate and discussions on the performance relative to natural and recycled aggregates and towards requirements for utilisation. The findings indicate substantial potential for utilisation, supporting the reduction of waste for deposit and development of the concrete industry towards a circular economy.
A critical perspective on Integrated Project Delivery (IPD) applied in a Norwegian public hospital project
2020
Does the IPD concept deliver as required and expected, and if not, how can that be explained? This paper is a critical realist inspired methodology based on a combination of the inductive and deductive approaches used in case study research. IPD is based on relational contracting between multiple parties, in this case between the Owner, Contractor, MEP subcontractors and a group of Consulting engineers who share control of the project. At the core of the concept is shared risk and opportunities among the parties in the IPD contract. Our theoretical perspectives are based mainly on the Principal-Agent theory (PA), Transaction Cost theory (TC), and its related incentives. This paper reports o…
