Great article Mark!
Head Spelunker Report:
I have spent the better part of this year coordinating an overall U/G site drawing for a new AP that Teck is set to build in 2017. We’ve had to dig thru the archives (late 1800’s-1980’s), ask for survey after survey, watch them excavate and find things that were never documented and apply some of the best guess work we could. Sometimes its felt like I’m just spinning my wheels and remodeling, re-cutting and revising the same 10 dwgs over & over again.
Biggest part was the relocation of 3 existing lines: 14″ Wastewater, 4″ Effluent and 6″ Sanity sewer (all pumped) that shared the same trench and just happened to run directly under where the new converter was set to go. Those 3 lines ran almost 2km crossed above & below a boatload of other services and had to be tied in to the new location in a 12hr shut down – no exceptions.
Tie-In’s were successful and the construction team has been more than happy with what we’ve done and outside of a few things the contractor took upon themselves to change it’s been pretty smooth!
I’ll be happy to crawl above ground to see the light of day and resume fighting for space on already overloaded racks of varying integrity LOL
