14. DESCRIPTION OF AMENDMENT/MODIFICATION (Organized by UCF section headings, including solicitation/contract subject matter where feasible.)

The purpose of this amendment is to provide answers to questions and provide a legible copy of drawing (CRL roof plans- Sheet A202.2). Also provided is the sign in sheet for the pre-solicitation meeting.

Q.1: The spec calls for ½" per foot slope to taper. Is that in the crickets only with ¼" per foot slope on the remaining areas of the deck?

A.1: Statement of Work Item 5.C, stated "The CONTRACTOR shall install new fully adhered tapered insulation to attain a minimum slope of ½" per foot." That will be changed to "a minimum slope of ¼" per foot so that the parapets and most roof curbs will not need to be raised, but the roof drains will need to be raised to attain the average R-30 insulation

Q.2: Existing RTU RA Duct on south side of RTU less than 2" above surface of the existing roof deck (See SOW IMG_0712 for photo). This area is too tight to allow removal and proper replacement of new roofing system. Contractor recommends sealing off this area with new roofing system and leaving existing portion of roof in place. Please advise.

A.2: Rooftop Air Handling Unit #3's duct on the

South side of the unit shall have its bottom sealed off with a new curb system, leaving the existing portion of the roof under the duct left in place.

Q.3: Areas of existing parapet wall cap intersect/underlay greenhouse end wall flashing and counter flashing (see attached Pics 1-4). The metal in these areas appears to be in good condition. R&R of the flashing and closure strips may require authorized greenhouse representative to remove and replace their components proprietary to their greenhouse system to maintain warranties. Contractor recommends replacing parapet cap around these areas in question, resealing these existing areas with approved sealant and or counter flashing and sealing, and providing appropriate sealant/fasteners where new wall cap overlays existing, to create water-tight seal(s). Please advise.

A.3: Existing Greenhouse end wall framing shall remain as is. But the existing parapet wall flashing and coping intersecting the GH end wall framing shall be removed and replaced. New details shall be required to be sketched by the fabricator after investigative removal of the existing intersecting flashings for approval by the Location Coordinator.

Q.4: Several existing (Abandoned?) roof penetration curbs are under 4" in height and maybe too close to the roof deck to provide warrantable roof for this project. This may require removal of sheet metal caps, reworking the curbs and replacing the caps. Is this acceptable solution or shall these location(s), Continued ...

if unused, be filled in and curbs/caps removed?

Curbs(s) in question are directly north of

Greenhouses A & B on flat roof.

A.4: Curbs questioned are directly North of GH A

& B on the flat roof. Abandoned roof penetration curbs and sheet metal caps are anticipated to have existing concrete curbs, therefore will need to be built up for adequate height for curb flashing details for warranty, and is applicable to the total HH Roof.

Q.5: H.H. Drawing 1 of 1 General Notes: Roof

Replacement Outlined in Green and Option1

Outlined in Red. Is this correct?

A.5: NO, That note was from the initial roofing project done in 2017. This is to be corrected to

"Roof Replacement Base Bid Boundaries are shown in Red." There are no option areas.

Q.6.: Please provide a higher quality drawing

A202.2. This is the main roof plane. The dimensions are not legible.

A.6: An additional drawing of A202.2 is attached, with the dimensions in metric.

Q.7: In the project statement of work, Item

5-Project Requirements Paragraph C states to install taper insulation with ½" per foot slope minimum. There are a lot of curbs and other units that might need to be raised if this slope is used. The typical slope on the roof is ¼" per foot. Please advise.

A.7: See the Answer to Question 1.
