617.03 Construction Requirements
617.03.1 General
Consult with the Project Manager and affected utility companies about the work prior to commencement of work. Obtain daily, safety circuit clearance from the servicing utility before starting work on existing series street lighting circuits. Pull cut-out plugs and place worker signs at cut-out boxes before work is started. Use rosin core solder in all electrical soldered connections. Pick up Department-furnished material and equipment from the Traffic Engineering Section, 2701 Prospect Avenue, Helena, Montana, and transport to the project as part of the contract unit price. Provide the Traffic Signal Engineer at least 5 business days’ advance notice before arriving to take delivery. The date/time arranged for equipment pickup will be mutually agreed to and be as close as possible to the contractor’s request. Repair or replace all existing improvements and equipment disturbed, damaged, or removed in performing the work at Contractor expense. The locations in the contract for signal and light standards, controller pedestals, conduit runs, pull boxes, illuminated signs, and appurtenances are approximate. The Project Manager will establish the exact field locations and elevations. Furnish and install all incidental parts not specified but necessary to complete or modify the traffic signal, lighting, or other electrical systems at Contractor expense. Make arrangements with the serving utility for providing service to the project. Work with the serving utility to determine the schedule for and exact location of the service. Pay all fees and energy costs used for temporary Contractor operations. The Department will pay the energy costs to operate signals and lighting used by the public. All systems must be complete and operable when the work is completed. Coordinate all construction activities to ensure all interim and/or permanent pavement markings and all associated signs are in place prior to the signal turn-on. Place new traffic signal installations into “flash” for a period of 3 to 5 days immediately prior to the turn-on. The traffic signal will be put into operation upon approval, and at the sole discretion, of the traffic signal engineer from the traffic engineering section. The sole discretion of the traffic signal engineer is based on the whether the project intent has been met, the completeness of the project, and the ability to turn on the traffic signal safely. Inform the Project Manager of the desired turn-on date prior to the time the signals are to become operational. Have the project manager inform the traffic signal engineer of the desired turn-on date at least 2 weeks prior to that date. The date arranged for the signal turn-on will be mutually agreed to and be as close as possible to the contractor’s desired turn-on date. 617 – TRAFFIC SIGNALS AND LIGHTING 2020 EDITION V5.1 617-2
617.03.2 Equipment Lists and Drawings

4.Documentation required by the QPL for items that are on the approved QPL list.
5.Submit signed documentation in accordance with Subsection 106.09 and the manufacturer’s certification that pole material and galvanizing meets specifications. Materials and equipment listed as approved on the QPL at the time that the list of proposed equipment and materials is submitted, may be accepted as a pre-approved QPL item in lieu of the normal submittal and approval process outlined in this section. Obtain further information and requirements on the QPL website, located at http://www.mdt.mt.gov, within the contracting/consulting link. The Department has 20 business days after receipt to approve the submittals. Upon receipt of the approved list of equipment and material, immediately order the materials and submit copies of the dated purchase orders for major items. Re-submit any disapproved items for Department review within 20 business days of notification of disapproval. Submit the invoices showing the shipping dates within 10 calendar days of the invoice dates. The calendar date or the number of working/calendar days allowed for completion of the contract will be adjusted by the number of days the Department’s review of the submittals overran the Department’s review time, if the Departments delay effects the Contractors operation as shown on the most recently reviewed schedule. No additional compensation is allowed for these Department-caused delays. The Department is not liable for any materials purchased, labor performed, or work delay (except as stated above) before approval of the required submittals. All material is subject to inspection after delivery to the project and during installation on the project. Failure by the Project Manager to note defective material or faulty workmanship during construction does not relieve the Contractor of responsibility for removing or replacing defective material or redoing work at Contractor expense. Inspection or sampling of certain materials may be made at the factory or warehouse before delivery to the site at the Project Manager’s discretion. No material rejected before delivery is to be delivered to the project, and all material rejected on the project must be removed from the work. Submit all equipment guaranties and warranties.
