24 Per the Finish Material Legend on A00.20 there are alternate materials listed (RF1 ALT., RF2 ALT., T2 ALT.), which are no found in the Division 1 Alternates specification. Please add these to this specification and associate a number (ex. Alternate #6) with each.

The alternates section in the specifications have been updated to include this information.

25 For RF1 ALT.: Finish Material Legend on A00.20 lists this as being installed in "BACK OF HOUSE CORRIDORS/STORAGE ROOMS." Please confirm that this is correct. Please confirm that Vestibule 01E01, Computer Area, Air Quality Lab, etc. (other areas shown as RF1 in the base bid) are not to be included in this alternate. Is Corridor 01F11 (CPT3 in the base bid) to be included in this alternate?

RF1 ALT would replace everything that is shown as RF1 on A04.01 except for the following rooms - Public Educ. & Vol. Stor. 01J10, Monitoring Equip. Stor. 01J11, Battery Charging & Stor. 01I13

26 For RF2 ALT.: Finish Material Legend on A00.20 lists this as being installed in "LABS." In the base bid RF2 is included in Chem Storage 01I09, Water Quality Lab 01J08, D.I. Water 01I06, and Bio. Lab 01J06. Please confirm that these are the rooms are to receive RF2 ALT. in this alternate pricing.

RF2 ALT would replace everything that is shown as RF2 on A04.01.

27 A specification for fire protection specialties has been provided, but none can be found on the drawings. Please show

these on the drawings. See Life Safety Plans on A00.04 and A00.05 for locations of fire extinguishers, cabinets, and brackets.

28 Per detail 9 on drawing A07.01 there is a recessed pan with floor drain in Lab Loading 01G02. This location is an existing slab-on-grade. Please confirm that a pan that is not recessed is acceptable. Also, provide a specification for this pan.

30 Per detail 2 on drawing A07.01 there is a work bench that is relocated. Is this OFCI? Also, in this detail there is a peg

(3)

31 There are multiple items tagged with Sheet Notes #11 on details 1 and 3 on drawing A07.03. Please provide a description of these items.

These are various items that will be relocated from the existing Bio Lab, including but not limited to work benches, loose floor cabinets and upper cabinets. These are all OFCI. The upper cabinets will need blocking in the wall for attachment.

32 Provide an elevation of the cabinets on the plan north side of the Bio. Lab. Please see detail 04/A07.03 for this elevation.

33 Provide elevations / section cuts / specifications of the items shown in the middle of Air Quality General Lab. These will be OFCI lab benches.

34 Per the plumbing there are P-3 sinks in the lab areas the are integral to the counter top and "provided by others." Per the only casework section cut (1/A08.00) the sinks are under mount. Please clarify and provide a specification for the P-3 sinks.

Further coordination is required with the user. We will resolve and answer this in the final Addendum (#3).

35 Sheet P01.01 does not clearly show the demo work to be performed. Line weights for existing system is the same as that

for the portion being removed. This may be misinterpreted. Lineweights for phases was originally assigned by REVIT and were left on default type. Lineweights have been adjusted and should be more visible.

36 Sheet M01.02 demo drawing is showing the same ductwork as the M02.02 drawing, but we are not demolishing and reinstalling the identical ductwork, correct?

Correct. For Dwg. M01.01, ductwork to be removed is shown dashed. Refer to demolition notes 1 and 2. Ductwork to remain is shown solid. For Dwg. M02.01, existing duct is shown light line weight and new duct is shown in a heavier line weight. New duct also has a new to existing duct connection symbol located at the new duct connection point. 37 Sheet M02.01 implies almost all new air distribution (grilles) since most are in heavy line weight. Is this correct? No. New grilles have a grille mark such as "A", "B", "C", etc. as shown on air device schedule on dwg. M03.01. Existing

grilles have an ( E ) listed at the end of the grille size and no grille mark. Slot diffusers in lay-in ceilings at the south end of the building are existing, as well as, many of the open return air grilles labeled with a keynote 2. Most of the the grilles on the north end of the building are new. New grilles are marked with a grille mark at the beginning of the grille size such as "A", "B", "E", or "F".

38 Sheet M02.04- what is the purpose of the 20’x14” “box”? This is assumed to be a duct but has no connections points. The existing RTU-1 supply air vertical riser with level 01 supply loop and return air ductwork is existing and is to remain in place. Revit shows existing ductwork as a light line weight and new ductwork shows at a heavier line weight.

39 Sheet M02.04 is not clear on what is existing and for reference only- it may be interpreted that we are installing new Supply air ducts (72”x24” for example), etc. This will lead to unnecessarily high proposals. Same for Sheets M02.02 and M02.03.

The existing RTU-1 supply air vertical riser with level 01 supply loop and return air ductwork is existing and is to remain in place. Revit shows existing ductwork as a light line weight and new ductwork shows at a heavier line weight.
