Amendment 02

Amendment No. 02 is issued to:

1) Provide the list of attendees at the site visit on 08/19/09 (included as a separate attachment); and

2) Provide responses the following questions:

Question 6: Can you please confirm that the scope of work for the Base Bid, Bid Option 1, and Bid Option 2 are correctly defined on the Cover Page of the Drawings. (See Revised Schedule of Items – B.2–attached).

ANSWER: The scope of work is correct. However, the roof deck is steel not concrete as stated on the drawings and was addressed in Amendment No. 01.

Question 7: Can you please confirm that Bid Option 3 on the Cover Page of the Drawings is not included in the solicitation and shall not be included in the bid.

ANSWER: Bid Option 3 is not part of the solicitation.

QUESTION 8: In Amendment No. 01 (question 5) an alternate was proposed which allows a change in the specification in the Project Manual from TPO 60 m. ATSM D 6878 to “Duro-last 50 mil membrane installed by a master applicator…with a 20 year NDL warranty.” Duro-last is a PVC membrane (not TPO as required by the project manual) meeting ASTM D 4434 (not ASTM D 6878).

May any PVC membrane of at least 50 ml membrane installed by a master applicator with a 20 year NDL warranty meeting ASTM D 4434 be acceptable so long as installation meets the manufacturer’s specification warranty?

ANSWER: The product specified is a 60 mil. TPO, white roof. The substituted product shall meet the requirements of the specifications. A Duro-last roof product is not an allowable substitution.

QUESTION 5: Would an alternate bid offering a Duro-Last product be accepted? A Duro-Last 50 mil membrane installed by a master applicator can be offered to the customer with a 20 year NDL warranty. ANSWER – AMENDED - This product is not and equal to the specified product. See response to item 8 above.

Looking at the site conditions and elements that will require such precision attention to detail and flashing requirements, the Duro-Last line of products along with expert installation will achieve a much more reliable result. ANSWER – AMENDED - This product is not and equal to the specified product. See response to item 8 above.

3) THE TIME AND DATE SPECIFIED FOR RECEIPT OF OFFERS HAS BEEN CHANGED TO SEPTMBER 9, 2009 at 2:00 p. m. Offeror's are required to acknowledge receipt of all amendments (if any) to this solicitation.
