Project Manual, Plans and Specifications:

Questions and Clarifications:  

Q1 - Do we need to design build the irrigation system to cover all the sod and seed (or just sod)? Is additional landscaping planned or is it still just the sod and seed based on the alternates?

A1 - There will not be any other landscaping. Sod and permanent seeding only as called out in the plans. Seed and mulch in areas if alternate 1 not accepted per previous addendum. No permanent irrigation is required. Contractor responsible for protecting and watering sod 4 weeks after install per Sod note on Sheet C551. 

Q2 Can you provide clarification about the Extruded Parapet Cap noted on page A7 of the drawings?

A2 – There is a better detail on A13. The parapet cap (aka coping) will be approximately 15” wide with a single slope to the interior. Please provide PAC-Continuous Cleat Coping System, 22 gauge steel. Black Kynar painted finish. Equivalent products may be submitted for approval.

Q3 - Can you specify what specifications for coverboard noted on A7?

A3 – See Spec Section 07 5419, Page 15, 2.2B – (1/2” fiberglass faced primed roof board, fully adhered)

Q4 - We would like some more Information about the Metal panel at the back of the parapet wall on page A8. Do all Parapet walls receive this Metal panel?

A4 – See Addendum # 4 Sheet A5 Wall Material Designations 

Q5 - PVC roof spec basis of design is Durolast 60 mil with no KEE . There is an approved substitution of 80 mil PVC KEE and a Not approved GAF 60 mil  PVC  KEE in addendum 3. What is the preferred specification?

A5 - Any substitutions shall meet the physical requirements of the specifications.  Ones that have been submitted that meet the requirements have been approved.  Ones that do not have been rejected.  For example, some manufacturers do not make a 60 mil product that meets the requirements but their 80 mil product line does, therefore they have submitted it. 

Q6 - Please clarify what types of cables are required for each outlet circled on E6. 1) How many cables are required for the floor boxes (circled in RED)?  2) What cables are required for the TV outlets if “X” means coax (circled in BLUE) 3) What is the green circle in the middle of the operations room (camera or data)?

A6 -     1)  4 per box

            2)  Ethernet cables only at those locations (2 per TV)

Q7 - For specification section 07-2800, please confirm that item 2.2A is not utilized and the only the weather barrier required is 2.2B, which is Tyvek sheathing or equivalent.

A7 – See Q8, A8 below.

Q8: - Specification section 072800 for moisture barriers describes sheet moisture barriers, similar to a Tyvek product. However, there are exterior metal stud/sheathing locations as well as exterior concrete wall locations. Please clarify the type of moisture barrier to be used at the different types of exterior walls. Also, if a different product is to be used at concrete wall locations, please provide a spec. 

A8 – Section 07 2800 MOISTURE BARRIERS.

a. In lieu of WRB sheet products listed, provide a continuous fluid applied WRB at all exterior wall surfaces, including cast-in-place concrete and gypsum sheathing, except as noted below.

b. Do not apply WRB at rear concrete wall, adjacent to the Mechanical Court. 

c. Provide a fluid applied air and water barrier membrane with a single component Silyl-Terminated Polymer (STP). Membrane. It shall NOT include a vapor barrier component.

Q9 - The wall legend on sheet A2 calls for 8” 16 ga. 4” C/C metal studs at the ICC wall. Please advise if this wall furr-out is intended to be spaced every 4” on center, or if this is intended to be every 24” similar to other wall types. 

A9 – Sheets A1, A2, A3 – WALL LEGEND – INTERIOR PARTITIONS: 8” WALL STUDS:

Change 4” C/C      to 24” C/C.

Q10 -. Will the 6" slab on grade be reinforced the same as the 4"slab on grade?

A10 – Yes

Q11 - Will additional reinforcements be required around the storm shelter wall block-outs for the column base plates?

A11 - No

Q12 - What is the expected finish on the exposed concrete wall at the Mechanical Court?

A12 - – Section 09 9100 PAINTING

Q13 - At the Mechanical Court, the roof is open.  How will the water drain out of that area? 

A13 - There are six 3” galvanized surface drain pipes through the east (plan south) court wall at the floor. Sheets A5, S4.03.

Q14 - Is Xypex or equal required in the concrete shelter walls?  Can Stego 10 mil vapor barrier be used in lieu of the Moistop Underslab product that is listed int spec section 03-3000?

A14 - Yes the Xypex is required in the shelter walls. Yes, Moistop Underslab is just the basis of design.

Q15 - In the spec section 03-3000, Section 3.11 Floor Flatness/Levelness Requirements, these requirements do not match ones listed in Note 8 on S1.01.  Which should we follow?

A15 - The requirements noted in the General Notes is acceptable.

Q16 - Tiling spec section 09-3000 section 3.2F: Please provide further details or specifications for the referenced trim.

A16 - Section 09 3000 TILING - All wall and floor tile to be Dal Tile “Advantage” Series. 12”X24” “Renoir Gray” floor and wall tile.  Equal products from other manufacturers will be considered.  Provide Schluter radius trim at outside corners and radius floor cove at showers, stainless steel finish.

Q17 - Will the equipment in the Mechanical Court be on individual housekeeping pads?

A17 - Yes. See Sheet M6 Key Notes 4,5.and Sheet E9 Detail E-GEN.

Q18 - On Sheet E8 of the HVAC Electrical Plan, multiple equipment disconnects are shown, including those serving HVAC units and other mechanical equipment. However, the drawings do not indicate the required enclosure rating for these disconnects. No designation such as NEMA 1, NEMA 3R (rain-tight), NEMA 4, or NEMA 4X is provided in the plan notes equipment callouts, or the disconnect symbols on the sheet.  We require clarification to ensure proper specification and installation of disconnects in accordance with project requirements and environmental conditions. Please confirm the required enclosure rating for the disconnects highlighted in red on Sheet E8. 1) Are these disconnects to be NEMA 3R (rain-tight)? 2) NEMA 4 / 4 or NEMA 1 (indoor rated)? Reason for asking is these disconnect enclosure ratings affect environmental suitability, code compliance, and procurement. The contract drawings do not currently identify the required rating, and clarification is needed prior to installation. The disconnects in question are highlighted in red below. 

A18 - Per Specification Section 262816-3.1(C), “Switch enclosures shall be rated NEMA I indoors in dry locations and NEMA3R outdoors and in wet areas.”  For the switches highlighted in red on the markup, only switches in Mechanical Room 164 shall be considered indoor.  Switches for units within Server Room 160 are integral/factory provided.N  All other switches shall be considered outdoors.  See project specifications for additional requirements for disconnect switches and electrical installation.

Q19 - Please provide a responsibility matrix of owner/GC provided items for electrical equipment referenced in divisions 27 & 28.  There have been multiple questions from subcontractors for these divisions (security access controls & structured cabling). 

A19 - The question related to cabling was addressed in Addendum #4, Question 2. The question related to the electronic access control scope was addressed in Addendum #4, Question 3. The contractor is responsible for installing a complete system as specified, see plan sheet E13 Access Control System Notes.
