About this file

Written by GovTribe AI ·

This is a Construction Safety and Phasing Plan (CSPP) drawing set prepared by H.W. Lochner for the City of Gallup, New Mexico, in coordination with the New Mexico Department of Transportation for the installation of a new AWOS-III P/T system at Gallup Municipal Airport under NMDOT Project No. GUP-24-03. The drawings depict the Phase 1 construction scope, which includes installation of a new Automated Weather Observing System and removal of the existing ASOS system within a 30-calendar-day completion window. The project site plan identifies construction limits, contractor staging areas, haul routes along Mendoza Road, aircraft access gates, and the locations of existing airport infrastructure including Runway 6-24, five taxiways, terminal building, fuel farm, hangars, and electrical vault. Construction personnel and equipment are prohibited from airport operations areas until NOTAMs are issued and aircraft operations are suspended. The contractor must monitor CTAF/UNICOM frequency 122.95, utilize hand-held radios, and maintain low-profile barricades with reflective sheeting and flashing red caution lights spaced no greater than 12 feet on center. Temporary erosion control devices must be installed prior to soil-disturbing activities, and any pavement rutting or damage caused by contractor operations must be repaired at the contractor's expense by project completion.

The CSPP details specify that runway safety dimensions include a Runway Safety Area of 7,915.66 feet by 150 feet, a Runway Object Free Area of 7,915.66 feet by 500 feet, and a Runway Obstacle Free Zone of 7,715.66 feet by 400 feet. Taxiway safety dimensions establish a Taxiway Safety Area of 79 feet wide and a Taxiway Object Free Area of 124 feet wide. Low-profile barricades must be Sherwin Industries 10-inch by 96-inch barriers or approved equal, weighted against propwash and capable of withstanding 100 miles-per-hour wind forces, with flashing red caution lights mounted and spaced at no more than 10 feet. The eight construction limit and staging area points are identified with specific latitude, longitude, site elevation, obstruction height, and obstruction elevation coordinates, all derived from Google Earth data. The contractor must coordinate with the airport manager during the pre-construction meeting for gate codes and keys, maintain airport surface cleanliness throughout construction, and remove all equipment, materials, and personnel upon completion of the AWOS installation and ASOS removal work.
