A. Three (3) exit lights shown on A4.01 & A4.02 have been added to electrical drawings. The attached sketches ESK-3.1 & ESK-3.2 illustrate the revision. Contractors are directed to refer to the Electrical lighting drawings and the attached sketches for the full scope of exit lighting. Changes are “clouded” as revision #3 on the above referenced ESK sketches. (2 pages)

B. Contractors are directed to refer to electrical drawings, sheet E3.1 & E3.2 for location of exit lights X1, X2, and X3. X1 and X3 are the same fixture, except for the fact that X1 is single-face, while X3 is double-face. Please see attached for cut sheets: X1 & X3 - Lithonia LE EL N; X2 - LITHONIA ELM2 (4 pages)

8. LOCATION OF UTILITIES BELOW STRUCTURAL SLAB

The foundation system for this project is a concrete raft of varying thickness typically 18-24". Due to the structural requirements of this type of foundation, pipes and conduits should not be located within the raft itself. All pipes and conduits will be required to be located below the raft and should be consolidated as much as possible in several primary trenches which can be recompacted. Vertical sleeves can then be used to pass through the raft. To avoid a random, haphazard installation, the Contractor shall submit a utility layout plan for review and approval prior to excavation. This would help in avoiding rerouting and reworking of pipes and conduits after installation. Please refer to the attached typical detail 16/S1.1 (1 page).

Please Note that bidders are required to acknowledge receipt of Addendum 1 in the Bid Form. Very truly yours, GLASS ASSOCIATES, INC.
