THIS AMENDMENT IS BEING ISSUED TO INCORPORATE THE FOLLOWING

INFORMATION INTO THE REFERENCED SOLICITATION

QUESTIONS AND ANSWERS

1. QUESTION: The tower spec in this RFQ calls for a “222G”. The “222G” specifications are for a 90 MPH windload with up to .75 radial ice. Later in the RFQ, it calls for a 140 MPH rated tower with no ice, and 60 MPH with 1.25 inch ice. Which is a different tower all together. Please clarify.

FAA ANSWER: As called out in the project Specifications in Section 2.1.3: - “Unless otherwise indicated” EIA Standard TIA-222-G (Structural Standards for Steel Antenna Towers and Antenna Supporting Structures” shall govern….. in addition to being in accordance with AISC and AISI specifications and engineering practices.

Specification Section 2.1.4 – “Service Conditions” – within the Tower Design Criteria… we have stated that the tower design shall be analyzed based on wind speed inputs of: Basic wind speed = 140 mph with no ice (0” of radial ice), and also 60 mph wind speed (with 1.25” of radial ice) included….

Therefore, we have chosen to increase both the wind speeds and the radial ice thickness input during the design and analysis of this tower….. If this was not “otherwise indicated”, then the default would be the 90mph basic wind speed with no ice, and 40mph wind speed with 0.75” ice thickness as indicated from TIA would apply….

Other criteria to be used in the analysis, such as; Tower Classification, Exposure category and Topography category are also stated.

Tower Design Criteria TIA Standard RS-222-G 140 mph Basic wind speed (with 0” of radial ice) 60 mph wind speed (with 1.25” of radial ice) Class – III Exposure - C Topographic Category – 1 Location – Bakersville, PA
