Extra Care Unit in Porthmadog
The new £7-£8m Extra Care Unit in Porthmadog – designed by architects Ainsley Gommon of Hawarden, with Datrys as Civil and Structural Engineers – has been submitted for planning approval on behalf of Grwp Cynefin.
As the Porthmadog area is well-known for its difficult ground conditions and susceptibility to flooding, Datrys has prepared a Flood Consequence Assessment for the site and identified the level to which the building must be raised.
Datrys also let and managed the borehold Site Investigation which revealed a sloping rock shelf beneath the estuarine deposits.
“We provided close supervision of the SI”, explained Engineering Geologist, Niel Williams.
“This meant that we could react quickly to the variable ground conditions as we found them.”
The proposed solutions being considered for the foundation design involve using deep piles or founding on the upper denser strata. Datrys has calculated values of potential settlement to design out the effects of differential movement.
