About this file

Written by GovTribe AI · Dec 9, 2025

This file contains the architectural and engineering plans for the Terminal Building Standby Generator Project at Texas Gulf Coast Regional Airport in Brazoria County, Angleton, Texas. The project is being undertaken by Brazoria County and involves the installation of a 300 kilowatt diesel-powered standby generator system to provide backup power to the airport terminal and Fixed Base Operator (FBO) support hangar. The plans include civil, electrical, and structural design details prepared by KSA Engineering, a Pape-Dawson company, with the civil work designed by Craig H. Phipps, P.E. and electrical systems designed by R. Cole Ferguson, P.E. The project scope encompasses the installation of a Kohler 300REOZJ or approved equivalent diesel generator with a weather and sound enclosure mounted on a reinforced concrete foundation, a 48-hour diesel sub-base fuel tank, generator maintenance concrete pads, and new automatic transfer switches (ATS-1 and ATS-2) to manage power distribution between utility service and generator output. The electrical infrastructure includes new three-inch conduit pathways, 400-amp and 200-amp disconnect breakers, and connections to existing electrical panels within the terminal building and hangar facilities.

The construction plans establish comprehensive requirements for contractor operations at the active airport facility, including a mandatory 72-hour advance notice to the airport and engineer before commencing construction activities, issuance of a Notice to Airmen (NOTAM), and strict adherence to airport security protocols. The contractor is responsible for obtaining all necessary permits from the City of Angleton and Brazoria County prior to construction, providing their own project office and temporary facilities, and bearing all costs associated with utility locating, dewatering, site restoration, and repair of any damage to existing airport infrastructure. Environmental compliance requirements include investigation for migratory birds and nesting activity, proper handling of hazardous waste, and adherence to wetlands protection regulations. The plans indicate construction must minimize disruption to airport operations, with all utility interruptions coordinated with a minimum 72-hour advance notice and electric service interruptions restricted to 10:00 p.m. to 6:00 a.m. hours. The generator foundation design requires over-excavation to a minimum of four feet below existing grade with compaction to 95 percent standard Proctor specifications, and the contractor must verify all underground utility locations before excavation begins. Upon project completion, all temporary work areas, haul routes, and stockpile locations must be restored to original or better condition at no additional cost to the owner.
