Sky-high surveying

“You can almost compare high-rise buildings with living organisms that breathe, shrink and expand. In order to handle all these small changes, you have to constantly monitor the building and make use of virtually all the competencies you have acquired over the years. ”

HLM’s senior surveying technician, Grant Fountain, says. He has almost 25 years of industry experience in the Tender, where he and Nikolaj Halborg are interviewed about HLM Land Survey’s specialty in building in heights.

Sky-high surveying

A specialized and innovative approach characterizes HLM Landmåling, which in recent years has been involved in a large number of the country’s most prominent high-rise buildings – a focus area that requires special skills due to the buildings’ dynamic nature.

“You can almost compare high-rise buildings with living organisms that breathe, shrink and expand. To handle all these small changes, you have to constantly monitor the building and make use of virtually all the competencies you have acquired over the years, “says HLM’s senior surveying technician, Grant Fountain, who has almost 25 years of industry experience.

MANY FACTORS MUST BE INCLUDED

HLM Landmåling is currently involved in the construction of three high-rise buildings in Carlsberg Byen – including Pasteur’s Tower, which will be 120 meters high and thus Copenhagen’s tallest residential property. Grant Fountain highlights some of the factors that make the work special:

“Our work is dictated to a large extent by the tolerances, which vary greatly and require a keen eye for detail. In addition, we are constantly aware of climatic factors such as the solar cycle, which has an effect on how much the concrete expands, just as extra settlement and wind impact are important focus points when building in height, ”he explains and continues:

“These are all factors that you have to take into account on the construction site, where production follows a tight schedule and must never stop. Therefore, for us, it is about identifying the windows where we can carry out our work with the least possible impact on the construction process. ”

A COMPLETE PACKAGE

HLM Landmåling embraces a wide range of measurement, monitoring and quality assurance – among other things due to a close partnership with the sister companies SMT Nordic and De Fakto Rådgivende Landinspekterer. “We use a combination of classic methods and state-of-the-art technology, and here it is a big plus that we can draw on SMT Nordic, which can monitor the construction itself and surrounding buildings, so you can intervene immediately if, for example, critical sentences,” says Nikolaj Halborg Sørensen, customer director at HLM Landmåling.

“With De Fakto Rådgivende Landinspektører, we also have the legal and cadastral competencies to define who owns what, so you are sure to start in the right place. This is particularly important in a country like Denmark, where we have an incredibly high standard of property rights,” he concludes.

HLM Landmåling has most recently won the land survey linked to the five high towers that KPC is constructing at Postgrunden in Copenhagen.

HLM Landmåling A/S is one of Denmark’s leading specialists when it comes to measuring, monitoring and quality assurance of height construction.
