Additional Q&A’s

1. Section 055000 - Metal Fabrications calls for the installation of downspout guards at areas where downspout is vulnerable to damage by vehicles or traffic. What is the hard count on this item?

2. What is the thickness/ga. of the existing structural metal deck?

3. Is a Unit Cost Item No. to be added to the pricing sheet to cover damaged or rusted metal decking replacement as set forth under Section 053100 – Steel Decking?

4. Is a Unit Cost Item No. to be added to the pricing sheet to cover damaged or deteriorated Sheathing as set forth under Section 061600 – Sheathing?

5. The insulation items specified under Section 072100 – Thermal Insulation are a more costly type of insulation than that specified under Section 075323 – EPDM Roofing. Is there a defined area of construction where these items are intended to be utilized.

6. Work related to Section 072119 – Foamed-In Place insulation is not clearly noted on the drawings or details. What/where is the intended use for this product?

7. Section 072500 – Weather Barriers (building wrap) indicates the intended use is for application over new sheathing. Is this to be limited to new sheathing and nailers over the top of exterior parapet walls and face of existing mechanical units? Is a unit cost to be provided for other unforeseen locations (as related to question 4)?

8. Two differing methods for installation of the roof insulation are put forth under Section 075323 – EPDM Roofing. Item 2.5 INSULATION ACESSORIES, B. Insulation Adhesives discusses the use of an adhesive application to attach roof insulation. Item 3.4 SUBSTRATE BOARD INSTALLATION, A.1. discusses the mechanical securement of the substrate board. Is it the intent to adhere any replacement insulation in place and mechanically fasten the substrate/cover board through all layers of insulation into the underlying steel deck to achieve the required wind uplift?

Answers

1. Approximately 48.

2. We have provided all of the information we have on the existing roof.

3. & 4. No, these will be treated as unforeseen site conditions if damage exists.

5-8. Have asked A-E to help respond to these (once I receive these answers I will upload)

Q’s

1. Is the ONLY insulation to be installed on this project the insulation determined to be “damaged insulation”.

2. Specifications section 075323-6 2.6 Walkways detail a flexible walk way. How many and where are these located?

Answers: 1. No. Refer to page 4 and 6 of drawings -- multiple details, multiple notes describe which insulation is to be removed, to remain, and which is to be replaced. Specifically, the internal roof gutter insulation must be removed and replaced to match grade of new roof system.

2. See note 9, page 5 of drawings.

Q’s Is the QC going to be full time and will he be able to perform any other duties? Is there any possibility that active Helicopters can be moved south of the building area to lesson any chance of a mishap such as a roof sheet getting away in a high wind and damaging a Helicopter? Also need to access that side of building with extended forks

Answer Full time QC not required. No, we cannot guarantee that helos will be able to be moved to accommodate the project.
