In connection with the establishment of Odense Light Rail, Spotland is carrying out the surveying at a large part of the line, about 15 km. Because of the bad GPS-signal in Odense, which is a very compact built-up city, we have added 150 extra fix-points to the existing 25 fix-points, or else we could not use our total station tool. After adding extra fix-points we can now use our total station tool and measure in which direction e.g. the curbs must be placed and and at what height they should be placed.
Spotland is helping Barslund and various contractors with the rebuilding of the stations on the new Ringsted-Femern Train Line.
Spotland is carrying out situational surveys of existing conditions as well as Topographical surveying of: drainage, draft pipes, masts, piles for noise shields, road stakeout, etc.
All stakeouts are performed with a total station, as the required tolerances exclude GPS measurements.
In connection with a coastal security project at Sjællands Odde Spotland has performed an area overflight and taken pictures with one of our phantom drones. Through photogrammetry we have converted images to 3D pointcloud images. The data can be used for multiple purposes, including visualizing conditions for the area down to the smallest detail.
In the picture, you see a pointcloud of more than 16,000,000 points, divided into approximately 25000 m². This corresponds to a density of 640 points per square meters. Based on this, it is possible to draw high curves or reduce the number of points to a level where you can use it to make a surface that can be used for further processing.
It is also possible to remove some of the points to give a more accurate picture of the actual surface, e.g.: land surface, cars, signs or crash barriers.
Odense Data Center is under construction and the data center’s amazing 55.000 m² is taking form. Spotland has four surveyors, and two BIM/VDC engineers attached to the project. Our work consists of stakeout, surveying, smaller projecting tasks, design for GPS-machines, measurement of quantities and As-Built documentation.
Our client Shoulders A/S has done pile driving of around 449 piles for a total of 8 foundations for the metro project in Nordhavnen. Spotland A/S was hired to do surveying of the piles, along with supporting the production with VDC services. One of the project milestones was delivery of as-built documentation.
As an addition to the usual as-built documentation, the VDC department developed a script in Grasshopper for additional documentation purposes.
The script simulates the pile intersection with a particular cutting elevation, as well as the rotation and tilt of the pile. The exact location of the pile has been modeled after measurements done by our land surveyor. Besides being able to document where the piles are placed, the involvement of the VDC department has provided the possibility of continuously performing collision controls. As a side benefit, the 3D model was also used as a cooperation and communication tool among project team to achieve increased transparency so that informed decisions could be made throughout the project.
