Photo 8: Bridge Crane Photo 9: Rahco Crane

8. (Photos 8 and 9) Bridge Cranes and Rahco Crane: There are three powerplant bridge cranes; two 275-ton capacity cranes, see informational drawings 1222-D-1323 and 1222-M-D-19-526, -527, -528, and one 50-ton capacity crane, see informational drawings 1222-D-1322 and 1222-M-D-19-428. The cranes span the entire width of the powerplant. Additionally, there is a 2000-ton capacity Rahco crane, below the bridge cranes, that spans the width of the powerplant. The top surfaces of these cranes have accumulated debris and stains from water and hydraulic oil leaks. The tops of the cranes shall be thoroughly vacuumed to remove all dust, dirt, foam, and other debris. The cranes and trolley catwalks shall then be cleaned using a water and soap solution to remove all stains. The cleaning is limited to the tops of all surfaces and does not include any vertical or bottom surfaces unless cleaning solution runs down any vertical surface. Those areas shall than be wiped down to ensure a uniform appearance is restored. Final surface appearance shall be uniformly clean.

Photo 15: Debris example on Top side of Sheet metal Cover

15. (Photo 14): Precast tee roof beam joints and behind the 29ga Sheet Metal Covers.

There are 146 Locations with a 29 ga Sheet Metal Covers. Cleaning behind the additional 8 locations at expansion joints will only occur where failed anchors are replaced per specification Section 05 50 00 – Metal Fabrications. Removal and re-installation of the covers per specification Section 05 50 00 – Metal Fabrications. After removal of covers vacuum up loose debris between where the concrete T-beams meet. Any damage found to the concrete T-beams shall be documented with photos to show the extent of the existing damage (if any).

Those photographs shall be numbered to indicate which plate (south to north starting with 1) and distance in linear feet from the west wall. These photos shall be turned over to the Government for use in future monitoring of the condition

B. Accessibility:

1. The parapet ledge, drain lines, air handling units, precast tee roof beam sheet metal covers, and high bay lights are accessible using the two scissor lifts mounted upon bridge crane 1 or the scissor lift mounted upon crane 4, (see Photo 16). However, the NE, NW, and SE corners are only accessible with the use of a 125-foot boom lift. The SW corner and areas adjacent to the observation deck are accessible via the observation deck. The 125-foot boom lift must be equipped with exhaust scrubbers (MSHA compliant) to be used in the powerhouse.

a. Previous contractors have hoisted an electric scissor lift onto the Eagles nest (exterior viewpoint on west face of the powerplant) for use to access the parapet wall ledges in that portion of the powerplant.
