Geosigma does “nothing”

Ge­o­sig­ma’s rock en­gi­ne­e­ring ex­per­ti­se is co­ming in­to play as part of de­ve­lop­ment work in the “In­gen­ting” (which li­te­ral­ly me­ans “nothing”) area of the town of Sol­na. In­gen­ting li­es direct­ly north of the he­ad of­fi­ce of the Swe­dish post of­fi­ce in Sol­na (known as the Fin­land fer­ry ter­mi­nal) and is cur­rent­ly ho­me to the Swe­dish In­s­ti­tu­te for Com­mu­ni­cab­le Di­se­a­se Con­trol. Skans­ka is the ge­ne­ral cont­ractor for the pro­ject, which in­vol­ves buil­ding around 48,000 m² of of­fi­ce spa­ce and ap­prox­i­ma­tely 700 new ho­mes. It al­so in­clu­des new in­f­ra­structu­re in the area, such as ro­ads and wa­ter and se­wage sys­tems.

This is a de­scrip­tion of the area pro­vi­ded by the or­ga­ni­sa­tion “The Fri­ends of Ha­ga-Brunnsvi­ken”: “The In­gen­ting fo­rest re­mai­ned in ex­is­ten­ce un­til the start of the new mil­len­ni­um, hid­den away between iron-age tombs and a gla­ci­al rid­ge with a vi­ew ac­ross Stockholm. Ne­ar­by lay the pro­per­ty of In­gen­ting. Ma­ny pe­op­le doub­ted that it ever ex­is­ted, but a rough map drawn by Ser­ge­ant E. von Plom­g­ren in 1891 shows In­gen­ting si­tu­a­ted north-west of the Karl­berg pa­la­ce gar­dens. Ey­ewit­nes­ses who li­ved in the gar­den cot­ta­ges ne­ar the Tom­te­bo­da post ter­mi­nal say that In­gen­ting was de­mo­lished when the ter­mi­nal was built between 1981 and 1983.

One spring day in the 18th cen­tu­ry, po­et and mu­si­ci­an Carl Mi­chael Bell­mann asked King Gustav III of Swe­den to gi­ve him a hou­se to spend the sum­mer in. “De­ar Bell­mann,” sa­id the king. “I ha­ve nothing (“in­gen­ting”) to gi­ve you this ye­ar.” To which Bell­man rep­li­ed: “If I can ha­ve In­gen­ting to spend my sum­mers in, I will be ve­ry gra­te­ful.” The king re­a­li­sed that he had been tricked and ga­ve In­gen­ting to Bell­man as his sum­mer re­si­den­ce. Ma­ny histo­ri­ans be­li­e­ve that this sto­ry has no ba­sis in truth.

Bell­man did spend part of his ti­me in Karl­berg, so why not in In­gen­ting? The town mu­se­um has a pho­to da­ting from around 1900 showing the hou­se at In­gen­ting stan­ding next to a lar­ge oak tree.”

Ge­o­sig­ma’s job in In­gen­ting is to car­ry out in­spec­tions of the rock in ex­is­ting tun­nels in the area which may be af­fec­ted by ex­ca­va­tion work abo­ve the tun­nels. We are al­so ac­ting as con­sul­tants on rock en­gi­ne­e­ring is­sues re­la­ting to the ex­ca­va­tion, in­clu­ding sta­bi­li­ty as­sess­ments, rock re­in­for­ce­ment and con­nec­tions to the tun­nels. So­me of the in­spec­tions ha­ve been car­ri­ed out in wet tun­nels, whe­re the wa­ter is flowing through the tun­nel it­self rather than through the pi­pes in the tun­nel. In ad­di­tion to Ge­o­sig­ma’s spe­ci­a­list ex­per­ti­se, this work requi­res ap­pro­pri­a­te sa­fe­ty equip­ment and re­scue ser­vi­ces in pla­ce.
