The firm has now lodged a planning application seeking permission to raise ground levels across the site, using use imported, inert fill material.
The location is Site 3, Atherton Way, backing onto the M180 and not far from Brigg Primary School.
The reasons for raising the ground level is in preparation for developing the site following the granting of permission last year for Site 3 to be used for industrial and office development.
Condition 12 of the planning permission granted by North Lincolnshire Council specified that all finished floor levels must be above 2.4m.
CLS says it has currently raised the ground level across the site to approximately 2.0m "with the anticipation of constructing the concrete slab for the future development from this level to achieve the required 2.40m AOD finished floor level."
AOD = Above Ordnance Datum...a vertical gradient....Related to MSL = Mean Sea Level.
ReplyDeleteCentred on a datum point in Newlyn, Cornwall...which was itself established upon statistics obtained between 1915 to 1921..
Similar datum point in Belfast for Ireland.
B4 1921, the AOD was at Victoria Dock in that famous city, Liverpool.
The dock is now filled in and now forms the site of the Irish ferries.
I was there some years ago...my daughter and co had been trapped at Dublin airport for 3 days just after Crimbo because of heavy snow. In desperation, my daughter phoned me..I arranged a passage on the Irish ferries for them....met them at 7pm in Liverpool....took them to Greenwich, London...When we got to the North Circular, traffic news said the Blackwall Tunnel was closed.
There was panic...they'd miss a drink at their local, The xxxxx...but my family are an enterprise lot and a phone call ensured we joined a lock-in til 4am!!!
Once I get started, you can't stop me, Nige...
ReplyDeleteWhile the AOD (height) is based on Newlyn; time is based on Greenwich ie GMT..
The government Weights and Measures Office held the datum for imperial measurements.
B4 this office was established, there were all sorts of misleading measurements. For example, the Roman Mile was shorter than an English Mile...there were also Scottish, Welsh and Irish miles....all longer than the English Mile...indeed, the Welsh Miles was over 3 miles compared with an English Mile...!
The Mile is still not universally defined; the American Miles remains a shorter distance...
So when studying historical documents, it's important to x-refer to which mile distance is being used.
On motorways, there are Count Up and Count Down markers...Based on the official starting point of the motorway, travelling away from such a datum, the markers will display 'A' with the kilo distance....the opposite carriage-way will show 'B' markers....
Anyway, not all things are perfect, my bathroom scales still keep telling me that I'm too fat!
It will be interesting to see what the ground survey reveals...
ReplyDeleteThere is a lot of overlay in this area of the Ancholme...the result of soil tipping build up following the various land drainage schemes and the canalising of the river.
However, there is a known Bronze Age trackway xing the Ancholme and the embankment running from Brigg to the motorway bridge is a likely place, if the trackway extended that far, to find such archaeological remains...
