Bergen Light Rail
Bergen Overview
• Bybanen = light rail:
• Bybanen Utbygging = light rail development
• Bergen dumped trams at sea in 1950’s, when rail lines were closed in Ireland
Tram in operation in Bergen City Strong public uptake Providing an alternative to the Car
Bybanen = light rail
Bybanen Utbygging = light rail development
Overall Bybanen Layout
• 5 stages
• 1 & 2 operational
• 3 Mott MacDonald
• 4 & 5 future
• Mountainous terrain means linear urban development
• Vision: 80% of workplaces and 50 % of homes within 600m of a stop.

Bergen Light Rail
Norwegian construction environment
• G-prog: combined specification and pricing document
• Norwegian construction contracts: • 7 civil and building, 4 technical, 4 specialist equipment.
• Client administers contract – consultant provides technical support
• Differing construction practices: • Blockwork, road gullies, concrete precast on steel frame.
• O drawings: to scale bird’s eye view
• Language: • Norwegian contract language
• Emails in Norwegian or English
• All Deliverables in both Norwegian and English
Bergen Light Rail
Optimisation Stage
• Optimisation exercise a contract obligation:
• Line: 50 optimisation points
• Depot: 25 optimisation points
• Each optimisation point to provide analysis and assessment of functionality, , overall strategy for implementation, risk factors, cost & programme reductions
• Decision Papers
• During optimisation and detailed design
• Identify issue
• Determine options, costs, programme, functionality pro’s and con’s,
• Make a recommendation
• Rastolen example
• Line optimisation report:
• 68 optimisation points
• 27 decision papers (optimisation stage)
• Depot optimisation report
• 25 optimisation points
• 50 decision papers

Construction Progress
........MMD has produced a fantastic
3d model which runs through a very
complex terrain. From what i have
seen on other projects, this is
maybe the most complete and
advanced infrastructure model you
can find today.......
.......A lot of the
things MMD has done in this project
with 3d models will probably set a
benchmark for how things, are
presented in 3d in future
infrastructure projects in Norway.
