Project Summaries - General Responsibilities

GEC, in association with P.B. Farradyne, was a major team member instrumental in the overall responsibilities for system design and development for several projects as listed below.

GEC responsibilities include the following:

Thorough and exhaustive study and review of available ITS technology.
Preparation of detailed construction plans and specifications for ITS field devices including dynamic message signs, closed circuit television cameras, radar vehicle detectors, video detectors, ramp metering, communication/wireless aggregation hubs, wireless communication systems, wireline communication systems, and systems integration.
Preparation of specifications for special tools, test equipment, spare parts, documentation, system demonstration period, and extended maintenance.

Construction administration services include shop drawing and equipment submittal review and construction engineering and inspection - both technical and on-site daily.

Baton Rouge Field Installation - Phase I

GEC was the lead firm in the system design and development for the Baton Rouge Field Installation Phase I.  The project included engineering services for the specification and preparation of detailed construction plans and specifications for the following:

3 dynamic message signs
10 closed circuit television cameras
24 radar vehicle detectors
1 communication/wireless aggregation hub
Optical communication system - Gigabit Ethernet backbone with Fast Ethernet local loops coverage area of 14 miles
Wireless communication system - 900MHz and 2.4GHz for local hops; coverage area of 6 miles
Special tools, test equipment, spare parts, documentation, system demonstration period, and extended maintenance

In addition, GEC developed standard procurement specifications for CCTV cameras, 40' RVD poles, 60' antenna poles, wireless transceivers for data, wireless transceivers for video, communication hub building, encoder/decoder pairs, and radar vehicle detectors.  Preparation of these specifications required close coordination with the LaDOTD Procurement Section as well as the LaDOTD ITS Unit.

Baton Rouge Field Installation - Phase II

GEC was the lead firm in the system design and development for the Baton Rouge Field Installation Phase II.  The project included engineering services for the specification and preparation of detailed construction plans and specifications for the following:

4 dynamic message signs
14 closed circuit television cameras
14 new radar vehicle detectors
22 existing radar vehicle detectors
2 communication/wireless aggregation hubs
Optical communication system - Gigabit Ethernet backbone with Fast Ethernet local loops; coverage area of 22 miles
Wireless communication system - 900MHz and 2.4GHz for local hops; coverage area of 8 miles
Special tools, test equipment, spare parts, documentation, system demonstration period, and extended maintenance

Furthermore, GEC developed standard construction specifications to be included in future ITS construction projects.  These specifications were modeled after Baton Rouge Field Installation Phases I and II technical specifications and formatted to the LaDOTD standard specification format. Included in these specifications are sections pertaining to CCTV camera sites, RVD sites, DMS sites, ramp metering device sites, ITS hub sites, optical fiber and electrical power distribution systems, system integration, spare parts, training, documentation, system burn-in, and extended maintenance.  Preparation of these specifications required close coordination with the LaDOTD Contracts and Specifications Section as well as the LaDOTD ITS Unit.
