MALU 257817 01 11 00 - 2

2. Integration of new systems to include a new mechanical system, electrical system, fire protection system and fire alarm system. Electrical work will require replacement of the existing exterior weatherhead with an underground electrical feed. The house is transitioning from a single phase to a three-phase system which will require coordination with Georgia Power for the installation of four new electrical poles between the Birth

Home location and Boulevard and a pad transformer to be located in the Gift Shop rear yard.

a. The electrical wiring and wiring for the fire alarm system will be replaced and will require strategic removal of plaster for access. See the Specification 02 4100

Selective Demolition for the process of probing at the plaster finish to establish the most minimal amount of plaster removal required for the replacement of this writing,

3. Interior work will include the repair to any plaster that is disturbed in the course of installing the new systems. The existing wallpaper is to be removed and replaced with replicated patterns.

a. The area with head height in the crawlspace is to be enlarged for new mechanical and fire protection equipment.

b. A mechanical room will be constructed in the attic.

4. Structurally, the brick masonry foundation walls and piers will be repointed. New CMU piers and 4 x 4 posts are to be added. New shear walls are to be added within the crawlspace. In the attic, connections will be strengthened. The existing kickers will be removed to maximize space in the mechanical room. The mid-span of the roof rafters will be supplementally supported with the new mechanical walls and a strongback beam.

5. There are two Bid Options as indicated in the B series sheets of the Construction Drawings.

1) Bid Option #1: The removal and replacement of the Gift Shop Retaining Wall

2) Bid Option #2 includes interior painting of all previously painted interior finishes.
