3D modeling of a slab-fram bridge in Tekla Structures : Methodology of a case-study (English)
Abstract [sv]

Detta examensarbete ämnar besvara huruvida Tekla Structures kan fungera som ett lämpligt 3D-modelleringsprogram för konstruktionsgruppen Nyanläggning och Bro inom Grontmij Sverige. Med goda erfarenheter av Building Information Modeling, s.k. BIM, och 3D-modellering inom andra delar av Grontmij så fanns en önskan att optimera gruppens arbetsprocesser med den senaste kunskapen inom området. Arbetet har fokuserat på att praktiskt modellera en fallstudie baserat på ett av Grontmij tidigare genomfört anläggningsprojekt. För att säkerställa fallstudiens representativitet valdes en plattrambro med stor mängd armering som ansågs ha en komplex geometri vilket potentiellt skulle fördelaktigt kunna representeras i 3D.

Vid skapandet av 3D-modellen och tillhörande ritningar delades processen in i tre steg; modellering, detaljering samt visualisering. Uppbyggandet av 3D- modellen påvisade unika för- och nackdelar i varje steg där också nedlagd arbetstid jämfördes med fallstudieprojektets tidplan. Resultaten visade att stegen modellering och detaljering (armering) uppvisade stora fördelar i relation till tidsåtgång. För steget visualisering, skapandet av 2D-ritningar enligt rapportens nomenklatur, var slutsatsen den omvända. Grontmij Nyanläggning och Bro rekommenderas därför att selektivt integrera Tekla Structures fördelar i sin framtida arbetsprocess samt fortsätta utvärdera programmet inom andra relaterade områden.

Abstract [en]

This thesis intends to answer whether Tekla Structures can function as a suitable 3D modeling software for the department of Transportation & Mobility within Grontmij Sweden. Given positive experiences from Building Information Modeling, so called BIM, and 3D modeling in other areas of Grontmij there was a desire to optimize the work processes of the department with the latest knowledge in the field. This report focuses on practical modeling of a case study, based on one of Grontmij’s previously conducted construction projects. To ensure a representative case study, a heavily reinforced slab-frame bridge was selected which was considered to have a complex geometry that potentially would be advantageously represented in 3D.

The process of creating the 3D model and associated drawings was divided into three stages; modeling, detailing, and visualization. The construction of the 3D model demonstrated unique advantages and disadvantages in each stage where also this thesis’ work plan was compared with the case study’s time plan. The results showed that the steps modeling and detailing (reinforcing) showed benefits in relation to the time spent. For the visualization step, i.e. the creation of 2D drawings according to the terminology of this report, the conclusion was the opposite. Grontmij’s Transportation & Mobility department is therefore recommended to selectively integrate Tekla Structures’ advantages into their future work process and continue to evaluate the program in other related fields.
