Request for Information/Market Survey for Non-Rotating Antennas to Support NAS Modernization and On-Going BNATCS Efforts

The document outlines a comprehensive project for the replacement of the existing 37-foot ASR-8 tower at Lihue Airport, Kauai, Hawaii. The scope of work includes dismantling and disposing of the old tower and associated infrastructure, and then furnishing, installing, and reassembling a new 37-foot free-standing ASR-8 steel tower. The new tower and its components will meet or exceed current FAA, OSHA, and building code standards, featuring hot-dip galvanized steel with Carboline coatings for durability. The project also entails significant upgrades and replacements of integral systems, including a new pressurized waveguide system, Heliax RF cabling, GRSC-PVC for electrical and control runs, and new electrical wiring. Additionally, the existing site security fence will be replaced with a new PVC-coated fence system, and a wash-down system with water capture will be installed. The foundation will be upgraded, and a new electric davit crane capable of lifting 2,000 pounds will be installed. The existing radome will be reused, and the site will receive new gravel/crushed stones upon completion. The project adheres to strict FAA governing standards and requires the contractor to comply with all environmental and Lihue Airport Authority requirements.

This comprehensive government file details the design, layout, and structural specifications for the Federal Aviation Administration's (FAA) ASR-8 Airport Surveillance Radar tower. The document includes detailed plans for the tower's main and mezzanine floors, stair layouts, and electrical installations. Key features include galvanized steel construction, specific bolt and gusset plate requirements, and detailed railing and grating specifications. It also outlines the lightning protection system, conduit runs, and power distribution for various tower heights (17 to 77 feet). The file further provides extensive information on foundation plans, reinforcing steel requirements for both dry and wet conditions, and detailed loading diagrams for dead and wind loads on the tower's piers. The file emphasizes safety standards, material specifications, and installation guidelines, including specific requirements for temporary feeders and weatherproofing.

The document outlines the design and fabrication details for an ASR-8 Tower, developed by the Department of Transportation, Federal Aviation Administration. It specifies anchor bolt settings, 10-foot section details, stair and rail configurations, floor beams, hangers, and handrails. Key specifications include hole diameters, hot-dip galvanization, steel stencil marking requirements, and detailed measurements for various structural components. The document emphasizes adherence to precise templates for drilling and welding, ensuring structural integrity and proper assembly. It also includes instructions for a bronze nameplate with specific material and finish requirements, highlighting the project's focus on standardized construction and durable materials for airport surveillance radar towers.

This comprehensive government file details the erection drawings and bill of materials for various sections of an ASR-8 Airport Surveillance Radar tower, ranging from 17ft to 77ft in height. The document includes detailed elevations, sections, and plans for the top, 10ft, main, and mezzanine floor sections, specifying structural components like beams, columns, and handrails. Bolt schedules, grating arrangements, and hold-down clip details are meticulously outlined, emphasizing galvanization and material specifications. The file provides instructions for erectors regarding bolt installations, washer and shim requirements, and field drilling. This document is crucial for the construction, assembly, and maintenance of the ASR-8 tower, ensuring structural integrity and compliance with FAA and Department of Transportation standards.

The Federal Aviation Administration (FAA) is conducting a market survey for non-rotating antenna radar technologies to modernize the National Airspace System (NAS) under the Brand New Air Traffic Control System (BNATCS) initiative. The FAA seeks to replace existing rotating antenna systems with non-rotating alternatives, including integrated, non-cooperative-only (NCSR-Only), and cooperative-only (CSR-Only) surveillance antenna systems. The survey aims to assess product maturity, technical readiness, deployment viability, manufacturing readiness, and integration considerations. Industry responses should include rough order of magnitude pricing, address operational considerations for various environments (enroute, terminal, remote/harsh, dense airspace), and detail how proposed solutions meet FAA objectives for improved reliability, detection performance, and reduced sustainment costs. The FAA is particularly interested in solutions that can interface with current BNATCS RSR radar systems (Raytheon ASR-XM/Condor Mk3 and Indra PSR-2D/MSSR-NEO) and provide information on Technology Readiness Level (TRL) and Manufacturing Readiness Level (MRL). Submissions must follow specific formatting guidelines, including answers to detailed questions provided in the announcement, and are due by May 29, 2026, at 3:00 PM ET. The FAA emphasizes that this is for informational purposes only and does not constitute a Screening Information Request (SIR) or Request for Proposal (RFP).
