This project includes the erection of 900 Tons structural steel at two new buildings and 3 small bridges in Montana.
The Dewatering Facility structure:
footprint of 106x132ft with 42 columns (26 spliced at 51ft)
7 elevated levels of steel framing
sloped roof with peak at 92ft above grade
3 sets of stairways
7 levels of elevated concrete deck and grating
roof includes 5 shop-assembled trusses that span 105ft
installation of two crane rails per CMAA tolerances
10 Ton Overhead Bridge Crane
The Loadout Facility is a smaller structure with:
24 columns covering a staggered footprint of 86x116ft
5 elevated levels of framing
sloped roof with peak 61ft above grade.
Both buildings are enclosed with insulated metal wall panels and metal roof panels.
Scope also includes the erection of 2 Takeaway Conveyor Bridges spanning from the Dewatering Facility up to the Loadout Facility. They are supported on 3 column bents each and are shop assembled in 4 segments with 3 bolted field splices. There is also a smaller Pipe Bridge, similar in design to the Takeaway Conveyors. It spans from the new Dewatering Facility to an existing structure.
