- NOTE: BID DUE DATE CHANGE TO: May 14, 2003 @ 3:30p.m. Questions and Answers from Site Visit on April 16, 2003 1. Q. Section 11601-2.1.6, Where is a HEPA filter required? A. HEPA filter is not required. 2. Q. Section 11601-2.2.1, the fume hood dimensions are 48" wide, 30" deep and 96" high. On the A-4 Casework/Equipment Schedule , 60" wide, 37" deep and 85" high. Which, if any, are correct? Would manufacture?s standard dimensions of 48" or 60" wide, 36" deep and 89?" high be acceptable? A. The fume hood should be a 60-inch wide hood. The standard 60-inch wide by 36-inch by 89?-inch high hood is acceptable. 3. Q. Section 11601-2.2.1.2 calls for ?" radius intersection of interior walls w/epoxy work surface. While this detail is very common where work surfaces are integral SS, it is highly unusual as specified. (See 4 following). A. Concur, the ?" radius for the epoxy counter tops is not required. 4. Q. Section 11601-2.2.6.c specifies a SS cupsink. This would appear to be further indication that perhaps a SS worktop in the fum hood was intended. While a SS cupsink can be mounted in an epoxy worktop, it will definitely not be "integral". A. Epoxy cup sinks should be provided. 5. Q. Sections 1601-2.2.2.2 & 12346-2.3.1 specify epoxy resin curbs/splashes 4" high. A-4 dimensions on elevations show 8" high. Which is correct. A. Eight-inch high curbs/splashes are required. 6. Q. Section 12346-2.3 Work Surfaces (countertops) are epoxy resin. Per 2.4.a see drawings for sink size - none are noted. A. Provide epoxy sinks consisting of either two side-by-side single-compartment types or one double-compartment types. Minimum size for single compartment type is 15-inch side by 18 - inch front by 8 - inch depth. Minimum size for double compartment type is 15 - inch side by 36 - inch depth. 7. Q. A-4 Sinks are dotted in as double-bowl which would be typical for SS integral is SS tops. Section 12346-2.3 specifies tops as epoxy resin. A. Provide epoxy sinks (see item 6 above). 8 Q. Sections 11601-2.3.3 & 12346-2.3.2 specify Chemical Resistant Plastic Laminate Shelving. We find none shown. Is this correct? A. Concur, no chemical resistant plastic laminate shelving is required. 9 Q. There is no fume hood airflow alarm specified or detailed. Hoods are required to have a method of airflow measurement with alarm is unsafe conditions arise. Kewaunee Air Alert 300 should be included. A. Yes, an airflow alarm is required for the fume hood. 10. Q. Section 11601- 3.3.2 requires that the fume hood be field tested to ACGIH 2080. The hood will be certified at the factory to perform in accordance with 2080. Bringing in an independent out side tester to perform the test in the field, the same one performed in the factory test room, will cost the best part of $2,000.00. Is the field test considered necessary or will the factory test certification be acceptable? A. The factory test certification for fume hood is acceptable. 11. Q. Asbestos Keynote #2 directs the removal and disposal of all gypsum board on walls and ceilings. Does this pertain to all wall and ceilings or only those scheduled for demolition? A. This keynote pertains only to ceilings and walls that will be "disturbed". 12. Q. There are not symbols for water lines. A. The identification of the different water piping symbols is given on sheet M-2 at the bottom right corner of the floor plan (in Equipment Room area). 13. Q. Is the sanitary piping to be cast iron? A. The sanitary piping can be the PVC piping called for in the specifications. 14. Q. Are the water lines to be routed through the ceiling or under the concrete? The water lines are to run through the attic and are to be insulated. 15. Q. Can the laboratory casework be wood casework? A. The laboratory casework to be provide shall be steels as specified. 16. Q. The vent hood shown on M-3 by note 5 in room 100 has a 12" exhaust pipe. This conflicts with the wall cabinet shown above the hood on elevation 4/A4. A. Concur, the wall cabinet shown above the vent hood need to be deleted from the project. 17. Q. Is the plumbing shown to be above the ceiling or under the floor? There is no insulation above the ceiling joists to protect any plumbing in the attic area. A. The water lines need to be routed above the ceiling and need to be insulated 18. Q. The R-11 insulation specified to be above the ceiling is only 3 ?" thick and not 6" as is usual for a ceiling. A. The R-value of the ceiling insulation (paragraph 2.1 of Specification Section 07232) should read R-19 in lieu of the R-11 indicated. 19. Q. Why not use metal studs on the outside block walls with plumbing being added. Otherwise the plumbing will have to be cut into the block or run in a gap in the insulation. Either way there is no insulation protecting the pipes. This also would make it much easier to get the 2" vent pipe on the roof. On the walls with no plumbing, using z channels instead of the hat channels will eliminate the large gaps in the insulation due to the width of the hat channels. A. The water lines will need to be insulated. Deeper metal framing section can be used to conceal the plumbing behind the finished wall surfaces, but will have to be consistent across the full width of the wall (no pilaster type areas for the plumbing). The plumbing wall in Toilet 103 can not be made deeper because of ADA space requirements. 20. Q. There is an emergency eye wash/shower to be installed but the plans do not call for a floor drain. Is a floor drain required? A. A floor drain is not required. **Offerors who have submitted a bid for the April 30, 2003 bid date may request that their bids be returned or can make changes to their original bid by mail or fax.
