Written by GovTribe AI · Apr 6, 2026

This Construction Safety and Phasing Plan (CSPP) document is prepared for the City of Gallup, New Mexico, through the New Mexico Department of Transportation (NMDOT Project No. GUP-24-03), and outlines the implementation strategy for installing a new AWOS-III P/T system at Gallup Municipal Airport. The project scope includes installation of a new automated weather observing system while removing the existing ASOS system, with all work to be completed within thirty (30) calendar days from the Notice to Proceed. The CSPP details construction limits, contractor staging areas, haul routes, and phasing requirements to maintain airport operations throughout the project duration. The document specifies that Runway 6-24, Taxiway A, Taxiway A1 through A5, and the Terminal Apron will remain open for operations during Phase 1 construction. Key safety requirements include contractor provision of portable hand-held radios, continuous monitoring of CTAF/UNICOM frequency 122.95, installation of survey lath at construction limit corners, temporary erosion control devices, and restoration of any pavement damage caused by contractor operations. Low-profile barricades with reflectorized striping, flashing red caution lights, and checkered orange-and-white flags must be installed per specifications, spaced no greater than twelve feet on center, with lights spaced at ten-foot intervals and capable of withstanding winds up to one hundred miles per hour.

The CSPP establishes construction limits and contractor staging areas at specified geographic coordinates with site elevations ranging from 6,470 to 6,471 feet, and obstruction heights capped at forty feet for construction limits and twenty-five feet for staging areas. The contractor is required to utilize designated access gates for project ingress/egress and electrical vault access, with coordination of gate codes during the pre-construction meeting with the Airport Manager. All airport surfaces must be cleaned and all equipment, materials, and personnel removed from work areas upon completion. The document references runway safety dimensions including a Runway Safety Area (RSA) of 7,915.66 feet by 150 feet, Runway Object Free Area (R-OFA) of 7,915.66 feet by 500 feet, and Runway Obstacle Free Zone (R-OFZ) of 7,715.66 feet by 400 feet. Taxiway Safety Area (TSA) dimensions are established at seventy-nine feet wide, with Taxiway Object Free Area (T-OFA) at one hundred twenty-four feet wide. The plan emphasizes that construction personnel and equipment cannot enter areas open to aircraft operations or the Airport Operations Area (AOA) until the area is closed to aircraft and Notices to Airmen (NOTAMs) are issued, with the contractor required to confirm NOTAM placement prior to AOA entry.
