Q&A’S ROUND 2

Question 1A – Sheet 1-E1 Electrical installation note #16 states to refer to specification section 26 05 53 for Color/label Requirements for conduit, box, cable/wire, and equipment. This specification section is not included in the project specification manual.

Answer 1A – This note was removed from the sheet as it's not applicable to this project.

Question 2A – Reference Sheet A-4A Room 5S09 and note FL8. Please provide brand name and/or photos of information to identify the existing storage bins. The new storage bins are to match and the information to match is needed.

Answer 2A – Existing storage bins are Par Excellence Systems, see pictures

Q&A’S ROUND 2

Question 3A – Reference Sheet 1- A3, Note DE3 is the only note that would indicate flooring demolition. The demolition pages do not identify the flooring to be demolished. Please note type of flooring to be removed in each room (sheet vinyl, ceramic, vct, carpet etc..).

Answer 3A – See keynotes on sheet 1-A2. Typical floor is vinyl tile, fully adhered.

Question 4A – Reference Sheet 1-A20 Equipment List A5215 TV Bracket Ceiling Mounted.

There is no specification for the ceiling bracket. Can you provide information on the basis of design?

Answer 4A – Basis of Design for TV Bracket is MOUNT-E-FD70. Addendum is revising TV locations; most should be mounted to a wall or column wherever possible

Question 5A – Can you provide the total height from the floor to roof deck for the Dialysis area?

Answer 5A – Per record drawings received by A/E, floor to top of roof deck is 11'-5 1/2". Deck is 4 1/4" thick.

Question 6A – Reference sheet 1-A11 details 8 and 9. These details show tube steel from floor to deck as support for grab bars. The details require a thru bolt to mount the grab bars to the tube steel. There is not a layout shown for these on the floor plan pages. It is very likely these will land in a location of a stud. What is the detail for locations that the tube steel lands in the space required for typical stud spacing? Secondly, please clarify the bolt? The shown thru bolt cannot be used as the wall will require drywall prior to mounting handrails.

Answer 6A – Grab bar support is VA standard. Typical stud spacing should be modified to accommodate. A/E is not responsible for means and methods of construction.

Question 7A – Reference sheet 1-A10 Detail “Partition Blocking-Backing Types” Blocking type “B” includes handrails up to 250#. Can you clarify which handrails are to be rated up to 250#?

Answer 7A – All handrails to use grab bar support.

Question 8A – Reference specification 10 28 00 and sheet 1-A20 Equipment Schedule. There is no basis of design for any of the toilet accessories. Please provide the basis of design.

Answer 8A – VA is providing the toilet accessories
