5. Selective demo of (E) 6" thick concrete panels as outlined.

6. demo louver. selective demo of EIFS.

7. Remove disconnect associated equipment as needed. Main breaker is located in electrical RM off main lobby

8. Demo control panel and compressor. (See note 12)

9. Condensing unit and ducting.

10. Demo evaporator coil.

Coil will have to be disassembled to be removed from mezzanine.

Move existing mixing box due to thicker coil.

11. demo condensate line.

12. Gov will provide tanks for recovered refrigerant and will dispose of tanks.

1. New evaporator coil.

2 .Line sets, controls, needed conduits will be mounted to bottom cord of roof truss using unistrut.

3. Polymer concrete trough will run under wall and shall be sized as needed for lines and conduits. Lines and conduits will be mounted as close as possible to the wall. Trough cover sall be cut and drilled to accommodate line sets conduits.

4. Connect existing feeder to new interior J-box thru wall to new exterior rated 400-amp fused disconnect switch. Feeder will return to interior and be ran in 2.5" conduit thru trough to mechanical unit.

5. Infill wall. 18 gauge metal framing. gyp board 8" type X moisture and mildew resistant. Provide backing. Patch any holes or damaged areas on entire south wall to a level 4 finish, 1 coat of primer with minimum of 2 coats of paint. EIFS cut back to nearest control joint or full panel. Match existing ridged insulation board thickness, match existing EIFS texture, style, profile and facility colors.

6. Polymer concrete troughs shall be rated for light traffic, 5' lengths, width sized as needed for lines sets and conduits.

Contractor shall verify size of polymer concrete trough to meet their needs.

House keeping pad will need to be poured and placed to accommodate the trough terminating underneath condensing unit as needed to make connections.

Trough will be installed prior to wall being built.

The 3 troughs shall be 5' long. 2 will be installed intact, 1 will be cut in half and adjusted as needed to create the ends with formed in-place concrete to create the end caps.

The trough end underneath the condensing unit shall have a 2-1

2" conduit poured and placed in the end of the trough and the conduit shall continued thru the slab and turned up in an open area in the bottom of the unit framing to make power supply connection.

PCC placed next to trough and cut concrete shall have edges finished with 18" radius, All other edges shall be finished with 34" radius.

Place 6" of 3/4- base rock compacted to 95% over compacted native soil.

New raised concrete pad shall match elevation of existing sidewalk then have a minimal slope to shed water away from the sidewalk. The house keeping pad will be extend 3" above the raised concrete pad and level in all directions.

And extending 4" beyond the base of the unit.

The cable trough example is made by Armorcast Products.
