1. The Scope of Work 7.3, States; Contractor shall install a PVC material that is durable, resistant to water, mold and UV rays. The material must contain a 40 mil thickness, 14X18 scrim, and tan in color.

In talking with the original shade manufacture (USA SHADE & Fabric Structures) it was discovered that the new specification to install the PVC material replacement fabric to the existing shade steel structure, that the original steel structure and existing foundations will not support the PVC fabric.

a) Is it the intent of the Government too have contractor redesign existing shade structure by a Licensed Structural Engineer as need to include possible foundations modifications as well but not limited to existing fabric attachment point modifications to support the new PVC material specification?

Answer: Please use the original fabric type.

b) Will the Government change the specifications back to an original HDPE fabric material as how the original shade structure was engineered thus, saving additional costs to have existing shade structure Re-Engineered?

Answer: Please use the original fabric HDPE fabric material type, with the traditional look as shown on the drawings and described during the site visit.

2. Please clarify that the scope includes the expectation that the redesign undertaken will require some modification to the fabric connections or connection details to the steel superstructure. These modifications would be included in the bid. If further modifications are determined to be needed to the steel superstructure (columns/trusses) itself – to bring it into compliance – that would entail a scope change.

Answer: It is assumed the modifications will be to the cables and connections, if the structure needs to be reinforced then a modification must be made as the structure is not part of the SOW.

3. ASCE 7 typically requires a compliance with a max wind of 110 mph with some possible reducing factors – please confirm that 100 mph wind speed is the specification for engineering.

7. Are the terms for Buy American applicable to the fabric? There is only one manufacturer in the US so source options are limited.

Answer: There will be a return to the original fabric, per the as built plans.
