TASK 7.0 SPECIFICATIONS Assignment of new equipment to be evaluated will be given by the Department and will involve one or all the following task.
Subtask 7.1 Identifying Parameters of New Equipment
The Department will assign to the consultant new equipment for evaluation. This equipment will be evaluated for usability and functionality in two categories, (1) as new equipment without being substituted for existing ITS equipment or (2) as new equipment with a comparison to existing equipment it is intended to replace. Evaluation parameters shall be listed and submitted to DOTD for approval prior to beginning the evaluation. New equipment that does not replace existing ITS equipment will require description of its ITS parameters. New equipment that will replace existing equipment will include as part of its evaluation a one to one comparison between the equipment’s functionality.
Subtask 7.2 Develop Design Installation Detail
An installation detail will be developed by the Consultant to be added to the Department’s ITS Standard Details. If existing equipment is being replaced then the detail will show retrofitting the existing mount and/or cabling. An associated icon will be devised identifying the new equipment on plan sheets.
Subtask 7.3 Analyze and Design Communications
An evaluation of communication alternatives to service ITS devices shall be done under this task. This task consists of coordinating and/or determining necessary frequency for radio transmissions, connecting with existing copper, coaxial or fiber media, or designing a communications path for ITS devices. Designs are required for connecting to existing communication media owned by franchised companies located within our right of way under permit.
Subtask 7.4 Develop Specifications
Specifications for the equipment being evaluated will be prepared by the Consultant at the direction of ITS Unit. TASK 8.0 PLAN-IN-HAND (IN-OFFICE REVIEW) The Plan-In-Hand task will involve an in-office review of the ACP plans & supplemental specifications at DOTD ITS Unit.
