Section 16482 Electrical: a. The Motor Control Center should be a NEMA 4 enclosure. Re: Section 16482.2.02.A.1: Change NEMA type 3R to type 4. Drawings: Sheet E1.7. Electrical One -Line Diagram. Change the notation on the motor control center from NEMA type 4R to type 4. b. Sheet E1.2 — Site Power Plan: Delete the electrical service shown from the existing pad mounted transformer on the CDOT site. Add a new pad mounted transformer, by Fort Collins Light and Power, on the east side of the drain pan, along the West property line. Service to the De -Icing Facility shall be from the new transformer. See Attachment F. c. Sheet E1-7 —Electrical One -Line Diagram: Change the note at the pad mounted transformer to read: "New pad mounted transformer by Fort Collins Light and Power". Change the note at the CT cabinet to read: "CT cabinet furnished and installed by E.C.". Change the enclosure type on the 800A main breaker and the 800A4P double -throw switch to NEMA 4. See Attachment G. 6. Thickness of cone. slab in Compressor Room: Detail 3/A3.2 notes this slab as 4". Dome Foundation Plan on S 1 notes it as 6". Structural drawing is correct; 3/A3.2 is incorrect. Slab should be 6" thick, and reinforced per S 1. 7. Detail 7/A3.2 shows the curb at the east side of the concrete drive extending below the bottom surface of the concrete drive, which it shows as 12" thick max. This is incorrect. The correct concrete drive (ramp) detail is shown in Section A -A on Civil sheet C-2. Drive is 7" thick. Bottom of curb is flush w/ bottom of drive. Curbs are poured integrally w/ the drive. 8. The liquid storage tanks in the Tank Yard are to be furnished by the Owner (City) and installed by the Contractor. Contractor shall arrange delivery schedule for the tanks with the Owner. The weight of the tanks (empty) is approx. 5,500 lbs. Lift eyes and tie -down flanges are provided on the top and sides of the tank. Tanks are to be placed on the level, 12'-6" diameter pads at elevation 100'-0" in the tank yard. (Re. Arch. Drawing Al.1 and Dome Foundation Plan S 1.) Contractor shall coordinate anchorage requirements with the tank manufacturer, including type of cast -in anchors, their locations and connections between anchors and tie -downs. The tanks are manufactured by Palmer Mfg. & Tank Inc., Garden City, Kansas. A drawing of the tank is provided as Attachment H. Five of the tanks are currently in the Streets Department's yard, and can be inspected by Bidders, upon request. 9. Pipe supports shown on M2.4 and M2.6 shall be furnished and installed by the Subcontractor installing the piping. 10. The concrete drain pan on the west side of the site is existing. It is incorrectly noted as new on AS.1. 11. Re: AS. I : "New" vinyl covered chain link fence is noted at the north and south property lines. This is incorrect. All chain link fencing shown is existing. No new chain link fencing is required for this work. Note that the existing chain link fencing along the east property line is to be removed as part of this work. 12. Section 13800 Operator Interfaces and Operator Control Sequences: The entire control system and all its components including the operator interface equipment and workstations are to be furnished and installed as part of this Contract. As noted, the Contractor shall coordinate specific details, design, and requirements for the system with the Owner. 13. Section 03100 Concrete Forms and Accessories: Note that paragraph 2.01-A- 2 requires HDO plyform sheets or plastic form liner for the Dome Building concrete walls. This requirement will apply to exposed portions of both interior and exterior faces of all the Dome Building concrete walls, including the Tunnel, Stair and Conveyor Shelter. Section 03300 Cast -In -Place Concrete par. 3.08-F requires a "grout cleandown" for exposed concrete surfaces of the Dome Building. This procedure will be required only for the exposed portions of the exterior faces of the exterior concrete walls of the Dome Building. 14. Section 03365 Concrete Sealer and Hardener & Section 01230 Alternates Alt. No. 2: Sealer Hardener is to be applied to all exposed concrete surfaces on the interior of all parts of the Dome Building. This would include the tunnel, including the underside of the concrete floor slab that forms the ceiling of the tunnel, all exposed concrete surfaces inside the Stair enclosure and the Conveyor Shelter and the Compressor Room. Note that per Section 07192, the exposed exterior faces of the concrete walls at the Dome Building are to receive a Silane-type Water Repellant, which is to be applied over the "grout cleandown" treatment described in section 03300. Concrete Sealer Hardener per 03365 will also be required on all the exposed interior concrete surfaces of the Conveyor Pit. No Sealer Hardener or Water Repellant will be required on other exposed exterior concrete surfaces such as the Tank Yard slab & containment curb or the concrete drive that approaches the Conveyor Pit. 15. Re: Plumbing drawing P1.1 and Civil drawings C3/C4/C5: Note that the civil drawings show the pit for the sump pump located further away from the building than the plumbing drawings. The location shown on the Civil drawings is correct. 16. Section 08710 - 2.02 Security Key Card Reader Locks: Par. C notes Electronic Locks as being supplied under Division 16 Electrical. This is incorrect. Electronic Locks are to be furnished installed as part of the Security Key Card/Card Reader System. Note that per electrical drawings, 120v power is to be provided to the Card Readers. Coordinate exact location(s) required for power with supplier of the Card Readers. All low voltage wiring including wiring to electronic locks is to be furnished and installed by the installer of the Security Key Card/Card Reader System. 17. Re: S1 Dome Foundation Plan: The tie rods in the slab shall be smooth 36 KSI rods. Coupling splices will be allowed. 18. Re: S1 Dome Foundation Plan and detail 3/A3.2: The 8" concrete sidewalls at the north and west sides of the 6" flat slab in the Compressor Room shall be reinforced with #4 rebar @ 12" o.c. ea. way @ the outside face of the wall.
