Geodetic surveys

Nordecon AS has performed geodetic surveys since 1992 

Long experience and highly qualified engineers enable us to be the best partner in performing all geodetic surveys that the customer needs. We perform works in Estonia, Sweden and Finland. The majority of the specialists of the geodesy department has been working for us over ten years. To validate their education and experience, all our specialists have received a professional certificate of surveyor by the Association of Estonian Surveyors.

In 2015 and 2016 we completely renewed the instruments available to us and now we have the high precision technology from Leica and Trimble. Since 2016 we are testing partners with Leica Geosystems AG, one of the world’s largest manufacturers and developers of geomatics products.

We have the following instruments available to us:

Leica MS50, Leica TS 16 and Leica TS15 tachymetres, for their management we use outdoor computers Leica CS20 with Leica Captivate software, in total 7 instruments.

Trimble S5 tachymetres with TSC 3 outdoor computers, in total 2 instruments.

The receivers of Leica GS14 or Trimble R8 GNSS are available to all surveyors.

For the precise levelling works we use Trimble DiNi 0.3 Digital Level.

For after-treatment and special works (point cloud treatment, calculating gears etc) we have the softwares of Lieca Infinity and Trimble Business Center.

For drawing works we use Autodesk Civil 3d 2017 or Autocad Map 3d 2013 software. For modelling we have Autodesk Revit 2017.

Within time we have contributed our knowledge and skills to the success of numerous unique and large projects. We perform works from surveying the ground plan to laser scanning. Here is the small selection of the works:

Construction surveying on the building construction objects:

Meerhof 2.0 construction (currently in work) – we perform geodetic surveying of the entire construction from courts, tracks to buildings, including surveying the consolidation of the neighbouring buildings within the construction

Reconstruction of Seaplane Harbour hangars – we performed construction surveying, also special works like determining and identifying the location and length of the cracks of the hangar shells

Construction works of the bureau building at Liivalaia 45, the Nordea House – we performed all necessary construction surveying works and carried out the construction-related consolidation observations of the neighbouring buildings.

Construction surveying on the road construction objects:

Reconstruction of the 20.87-30.7 km of Meoma-Alatskivi section (currently in work) - we perform all construction surveys, including necessary calculations of volume and control measurements. 

Planning and construction of V construction area of the western detour of Tartu – we participated in all working stages from planning to delivery.

Planning and construction of the Aruvalla-Kose section of E263 Highway - we participated in all working stages from planning to delivery.

Construction of IV construction area of the western detour of Tartu - we participated in all working stages from planning to delivery.

Planning and construction of I construction area of the eastern roundabout of Tartu - we participated in all working stages from planning to delivery.

Planning and construction of Mäo traffic junction - we participated in all working stages from planning to delivery.

Construction of the Vaida-Aruvalla road section – we performed geodetic surveys, including necessary calculations of volume and control measurements for the larger part of the object.

Engineering geodetic surveys:

II and III stage of the construction of Tivoli apartment buildings – we performed the laser scanning for the historic ships found during the construction works

Consolis Parma factory (Nummela, Finland) – the pre-renovation measurement of the bridge crane tracks and processing the trueing data and trueing the crane ways.

Planning and construction of V construction area of the western detour of Tartu – we performed works on all bridges and constructions, including the measurements, scanning and consolidation works necessary for the load testing of the railway viaduct

Construction of Lõõtsa 5 bureau building – before the façade works we performed laser scanning surveying of the building’s façade

Planning and construction of I construction area of the eastern roundabout of Tartu – we performed all works from establishing ground mesh to preparing the drawings, also railway embankment consolidation surveys, calculation of surface volumes and works on the established railway viaduct.

Establishment of temporary railway-detour passes for Ülemiste traffic junction – we performed all works from establishing ground mesh to preparing the drawings, also railway embankment consolidation surveys, calculation of surface volumes etc.

Planning and construction of the Aruvalla-Kose section of E263 Highway - we performed all works from establishing ground mesh to preparing the drawings, including all works on the established bridges, viaducts and ecoducts, plus the calculation of surface volumes etc.

Construction works of the Koidula border station (4 new viaducts were built and 3 existing viaducts were renovated) - we performed all works from establishing ground mesh to preparing the drawings, including railway embankment consolidation surveys, calculation of surface volumes.

Closing of Narva ash field no. 2 - we performed all works from establishing ground mesh to preparing the drawings, including the calculation of surface volumes and organisation of 3d machine control.

Closing the radioactive waste deposit in Sillamäe - we performed all works from establishing ground mesh to preparing the drawings, including the calculation of surface volumes and organisation of 3d machine control.

Construction surveys

State road No 29, the section of Märjamaa – Koluvere km 2.583–14.40 – creating a ground mesh, construction surveys (about 81ha) and laser scanning of Sipa bridge

Performing geodetic and geologic surveys of state road 35, the section Iisaku-Tudulinna-Avinurme km 0.7-28.5. The volume of the surveys about 106 ha.

Into inventory of waste pollution objects in 2014-2015. Geodetic measurements of the rivers Purtse and Erra and the creek Kroodi. The volume of the surveys about 55ha.

Geodetic surveys Estwin ELA 037, 056, 060 & 062. The volume of the surveys is about 1000ha.

This is only a small part of our works; for more information, please contact us.
