Mätchef - Road 261 Ekerövägen E1, Tappström - Lindötunneln Ekerövägen will have an additional lane between Nockeby and Tappström in the direction of Ekerö, so that it will be easier for the buses to get through in rush hour traffic. A new, opening bridge 120m long 4-span steel-concrete superstructure with turned steel sections on Tappström is to be built.

Contract sum: SEK 340,000,000

Surveyor - Lilla Lidingö Bridge for Implenia Sverige AB, the new bridge, which crosses the Lilla Värtan between Lidingö and Stockholm, is 730 meters long with 16 bridge piers and 15 spans and it is one of the longest bridges in Sweden. The bridge width should be just over 16 metres, of which 7.4 meters should be for pedestrians, cyclists and moped drivers and 8 meters for tram traffic. A tension-reinforced concrete bridge with the foundation for the bridge supports in the water, which represents a technical challenge.

Contract sum: approx. SEK 600,000,000

Surveying engineer - Kistagren cross-track, the cross-track is extended with the Kistagrenen, which stretches from Norra Ulvsunda in Bromma on to Kista and connects to Helenelund in Sollentuna. The project includes several detailed plans that enable the expansion of Kistagrenen within the city of Stockholm.

Contract sum: approx. SEK 520,000,000

Surveying engineer - Slussen project, expansion of the new Slussen is one of the largest urban transformation projects in Sweden. The SEK 12 billion project in collaboration with the City of Stockholm aims to create a dynamic district that responds to its historical context and transforms the city centre.

Contract sum: approx. SEK 12,000,000,000

Surveying engineer - FUT- Administration for expanded subway, Stockholm's subway is about to be expanded. Almost thirty kilometers of new tracks and eighteen new stations on four routes. The Stockholm region is responsible for the expansion and planning is well underway. It is an extensive and complex project.

Contract sum: approx. SEK 25,000,000,000

Surveyor - Citybanan, citybanan is a railway tunnel under central Stockholm in Sweden that is used by the Stockholm commuter train. The track is 7.4 km (4.6 mi) long, two-track and electrified. There are two stations: Stockholm City station is located directly under T-Centralen, which is the central station on Stockholm's subway. The Odenplan station is the second station and it is located at the Odenplan metro station.

Contract sum: approx. SEK 16,000,000,000

Surveyor - Nacka Kvarnholm connection Phase 1, an asymmetric arch bridge consisting of a 145m steel arch that transitions to a 48 long bridge of prestressed concrete. The bridge span looks slightly curved from the top of the bridge. This leads to a remarkable solution in the geometry of the main arch girders which have a dynamic slope towards the center of the curve to then compensate for the effects of the forces. Each arch beam has its own inclination angle and radius to optimize the forces in the structure. The superstructure consists of a composite construction where the steel structure forms the structural basis for the concrete carriageway slab. The connection of the bridge on the mainland was also part of the project. It is a long rock tunnel of 260m and a 46m long connecting concrete tunnel in an open pit. A separate long girder bridge of 44m was built on a separate road for pedestrians and cyclists. There are even various concrete retaining walls and a road construction of about 1km with water pipes and electrical installations. The design was handled internally by the technical office in Germany and in coordination with the bridge designer LAP-konsult.

Contract sum: SEK 253,000,000

Surveying Engineer - Sava Bridge Belgrade, The Sava bridge project was a multinational project by Porr Austria, DSD Germany and SCT Slovenia. The Sava Bridge, located in Belgrade, Serbia, is one of the world's largest single pylon asymmetric cable-stayed bridges with a total length of 929m between deck expansion joints. The foundation of a 220m pylon is a circular slot wall with 113 drilled bridge piles. The main span is constructed of 8,600 ton steel bridge construction, supported by 80 stay cables with a maximum length of 373 meters which is counterbalanced by a prestressed, reinforced concrete span of 200 meters. The approach road to Novi Beograd is constructed as a prestressed, reinforced concrete side span of 388m as a continuous box girder bridge. The total width of the deck is 45m and it is designed to carry six lanes of vehicle traffic, 2 tracks for a new light rail transit (Light Rail Transit) and two pedestrian/bicycle lanes. The project contains many ramps of 10-25m height with a total length of 3,200m and a roundabout of 10m height and 100m length which is also called elevated ring.
