In case of conflicts between this Addendum and previously issued documents, this Addendum shall take precedence. Acknowledge receipt of this Addendum in the space provided on the Bid Form. Failure to do so may subject the Bidder to disqualification. This Addendum consists of FIVE (5) pages and SIX (6) enclosures with supporting pictures. Item No. 1: Item No. 2: Item No. 3: Item No. 4: Item No. 5: Item No. 6: Instruction to Bidders, item 7, requires the Bidder to supply an Insurance Binder with their bid. The bid documents do not indicate any insurance requirements. Please clarify the insurance requirements so that we can obtain the required document to submit with our bid. SEE ENCLOSURE No. 1. It was requested at pre-bid meeting on September 3 rd, 2015 for additional information on existing concrete slab thickness. SEE ENCLOSURE No. 2. Wall types 3A, 3B & 3C are called out without sound insulation. Theses wall types are shown to be used within the shower room areas. Please confirm the walls called out on Detail 2 on A2.4 do not require sound batt insulation? CONFIRMED, AS DESIGNED. Would it be acceptable to use a shaft wall assembly, such as WP-6850 in lieu of wall type the elevator shaft shown on Detail 1 on A2.4? I WOULD NEED TO HAVE A SUBMITTAL OF WP-6850 TO REVIEW, IT WOULD HAVE TO HAVE SAME FIRE-RATING, LOAD-BEARING/LATERAL STABILITY AND BE ACCEPTABLE TO BOTH FIRE MARSHAL AND ELEVATOR MANUFACTURER. IF ALL THESE ARE REQUIREMENTS ARE MET THEN YES. Provide collateral loading to be applied to the bottom chord of mezzanine floor joist. Spec Sec , page #2, item B references a collateral load requirement of 10 psf for the building design, please clarify the collateral load requirements if any for the bottom chord of mezzanine floor joist. USE 5PSF FOR THE TOP CHORD AND 5 PSF FOR THE BOTTOM CHORD OF THE JOISTS. Spec Sec , page #1, item 1.3 / B - references AISC. The AISC no longer applies to Pre-Engineered Metal Buildings. The AISC has been replaced with the IAS Certification Standards. This can be confirmed with the MOA / Mark Panilo PRE-ENGINEERED METAL BUILDING TO BE COMPLIANT WITH AISC AS APPLICABLE. IAS IS A QUALITY CERTIFICATION PROGRAM AND NOT REQUIRED FOR THIS PROJECT.

2 Item No. 7: Spec Sec , page #3, item 2.1 / I - references red shop primer. Spec Sec , page # 5, item 3.1 / A - references gray shop primer. Please clarify. PROVIDE GRAY STEEL. Item No. 8: Item No. 9: Item No. 10: Item No. 11: Item No. 12: Item No. 13: Page A3.3 references PEMB sub-framing to be Galv. (silver) Will prime painted PEMB secondary sub-framing (painted to match prime painted primary framing) be considered or accepted in regards to cost effectiveness. PROVIDE G-90 GALVANIZED SECONDARY SUB-FRAMING. Page A6.2. Will increased deflection design limits to the PEMB be required for drop ceiling areas. If so, please clarify exact locations and confirm the required deflection limits in these areas. NO. Page S2.1, general notes #5. Bottom of steel to be minus 12. Please confirm/clarify if this is for all PEMB columns, i.e. interior and exterior perimeter PEMB steel columns. ALL PEMB COLUMNS SHOULD BE SET MINUS 12". Page S5.1. It was originally assumed that the exterior hot dipped galvanized stair assembly would be self-supporting (stand-alone), with structural foundation & footings and designed with self-supporting bracing. Per detail #8 on page S5.1 this may not be the case. If the exterior stair assembly is assumed to attach to the PEMB, the PEMB Manufacturer will need to know the loads imposed on the PEMB structure (seismic, wind, etc.) and the location(s) of the vertical girt shown in the detail so that the connections and support members can be designed and sized properly to accommodate the imposed loads. Please clarify and provide information. NOTE: the penetration through the insulated wall panel (PL1/2x4x1-3 ) may be a frost build up area, it is also assumed that this connection plate is required to be hot dipped galvanized. Please clarify. FIELD LOCATE PER THE DETAIL, SIZE MEMBER/CONNECTION FOR A 2 KIP HORIZONTAL LOAD, PER DETAIL THE CONNECTION PLATE IS PER THE STAIR FABRICATORS AND IS GALVANIZED. Page S5.1, detail #2 and #5 shows PEMB columns to be set on leveling nuts with a 3/4 grout spacing. It is common and most typical for PEMB structures to be designed for columns to sit on - full base plate size full load bearing - smooth concrete level surfaces. Can this detail be modified to accommodate a standard PEMB application. THE DETAILS DON'T SPECIFY LEVELING NUTS, CONTRACTORS OPTION YOU SHOULD COORDINATE WITH THEM ON HOW THEY WANT TO ENSURE A LEVEL SURFACE. I NORMALLY SEE EITHER LEVELING NUTS OR SHIM PACKS, BUT THIS IS BETWEEN YOU AND THE GENERAL. Page A3.1 South Elevation. 5 ea. Mechanical Arctic Hoods. For PEMB design provide sizes of the required PEMB framed openings, sill heights of these framed openings, and the weight each framed openings is required to support. THERE ARE 6 HOODS ON THE SOUTH WALL, NOT COUNTING THE SMALL HOOD IN THE ELEVATOR MACHINE ROOM. THE OPENINGS NEED TO BE LARGE ENOUGH FOR THE DUCT TO FIT THROUGH WITH AN ADDITIONAL 1/4" TO 1/2" SPACE AROUND THE DUCT FOR FLASHING/COLLARS. M3.1 SHOWS THREE OF THE SIX; 20/12 HRV EXHAUST, 28/12 HRV SUPPLY, AND 22/22 EF- 3 EXHAUST. M3.2 SHOWS THE OTHER THREE OF SIX; 2 EACH 18/18 EF- 1/EF-2 EXHAUST AND 24/80 MAU S SUPPLY AIR.

If so, please provide all necessary information. THE LOADING OF THE PAD AND EQUIPMENT IS IN THE UNIFORM LOADING REQUIREMENT, NO ADDITIONAL LOADING REQUIRED. Page A4.2 Elevator Safety Beam. This specific beam will require two additional beams connecting between main frame rafters in order to be supported. If this elevator beam and any other structural members are to be provided by the PEMB Manufacturer opposed to the elevator contractor please provide the hoisting capacity and loading requirements for the specific elevator safety beam. THE GENERAL NEEDS TO SUPPLY YOU WITH REQUIREMENTS PER THE ELEVATOR MANUFACTURER THEY CHOOSE. SEE ENCLOSURE No. 5. A3.1 Exterior Finish Schedule - please clarify. A.)
