Rewired ten existing Hold Signs and installation of two new Hold Signs, and 380 linear feet of 4-way Underground Electric Duct. To power additional lighting, inadequate 7½Kv regulator was replaced with three 7½Kv and one 15Kv Constant Current Regulators, allowing three levels of intensity controlled manually or by radio transmission. All electrical design was underground and in accordance with FAA standards.
Runway 6-24 Parallel Taxiway Reconstruction
Rehabilitation of Plymouth Airport's 3,500 linear foot, construction of new taxiway on Runway 15-33, installation of taxiway lights along 15-33 parallel taxiway, and construction of security fencing. Responsibilities included collection and evaluation of existing plans, pre-applications, and survey data; preparation of design drawings and specifications and construction cost estimates; and management of bidding and other construction services. During design phase, DuBois & King attended hearings to explain designs and plans to regulatory agencies. Prepared grant applications for submission to FAA and Massachusetts Aeronautics Commission and provided administrative assistance in management of grant monies. Attended preconstruction conference and provided construction management and resident inspection services.
Master Plan Update
Comprehensive Master Plan Update to guide airport development for next 10 to 20 year period. Planning services consisted of intensive review of both ground and air requirements and recommendations for future changes and improvements. Airside elements reviewed included current and future types and levels of airport operations and need for runways, taxiways, holding aprons, and safety areas to support operations.
Groundside elements were reviewed in the context of support for air operation needs. Examined need for new municipal administration building with fixed-base operations center and offices for airport commission, additional corporate and T-hangars, and industrial and commercial development on airport property.
Master planning study included computer-modeled noise level study of both present and projected operations and basic level of environmental impact study for each recommended airside and groundside element.
Throughout planning process, met extensively with Airport Commission and committees of users and citizens. Meetings informed Commission and public of study's progress and obtained information about needs and problems of those who use airport and are affected by its operation.
Fuel Farm Upgrade
