The answer provided under Amendment 000004 was not applicable; therefore, the answer is provided as part of this amendment.

The concrete design does not appear to be adequate for the building uplift and the curb on top of the slab is inefficient. Can alternate, engineered designs be proposed that meet the apparent design criteria?

Answer 01:

The curb is not a structural component of the concrete slab. It is intended to assist in rodent control and water intrusion.

The footings are currently sized for a building that has not been fully designed, and are based on preliminary calculations. Once the building submittal from the selected contractor has been approved through the submittal approval process, the foundation design will be revisited to determine if modifications are needed. The final foundation load calculations are required from the actual building manufacturer in order to verify the footing sizes and provide a final design and footing size, this is a submittal requirement per specification 13 34 19.

Question 02: No reference indicated

What is the R-value in Bay 7 for the walls and the ceiling?

Answer 02:

Question 06: Refer to Specification Section 13 34 19, Paragraphs 1.9.B. and 2.3.A.

Specification section calls for a t-year warranty for … coverage for rust and corrosion and weather tightness of the building. Paragraph 2.3.A. calls out for a screw down roof based on the purlin spacing and rib height. There is not a screw down that provides an extended coverage for weather tightness according to the responses received. Only a standing seam roof provides this weather tightness coverage and it has coverage of only 24” vs. the specified minimum 36”. What is the intent of the design, to have an extended leak warranty for the roof or to meet the letter of the specification?

Answer 06:

Provide the extended leak warranty with a standing seam roof.
