Section 5: High Mast Lighting Inspection and ServicingAnchor: #i1000434
Inspect high mast lighting poles and assemblies and provide proper preventive maintenance. The inspection and servicing routine outlined in this section should be performed every time the lamps are changed or the ring is lowered for any reason.
For general guidelines on maintenance practices related to highway illumination, see the Maintenance Operations Manual, Chapter 4, Section 3. Also the Maintenance Management Manual, Chapter 3, explains the “maintenance level of service” concept, and Section 2 of that chapter provides the maintenance level of service guidelines for highway illumination.Anchor: #i1000463
Documentation (Inspection Form)
Personnel carrying out inspections of high mast lighting should document their findings using the Inspection Record for High Mast Lighting Pole Assembly form (TxDOT 1409) or a similar form. Districts must retain these completed inspection forms for a minimum of three years.
A sample inspection form is provided in Appendix A. This sample may be photocopied as necessary. Copies may also be obtained from TRF. A Microsoft Word version of this form is also available through the online version of this manual (click on the form number above).Anchor: #i1000482
Items to Inspect
The entire lighting assembly and pole should be inspected each time the ring is lowered for maintenance. Items to be checked and maintained during these inspections are listed on Form 1409 in the form of a check list.Anchor: #HIIMEMKL
Replacement fixtures for high mast lighting must be obtained by special order. There are many different types of fixtures on the various high mast poles. Each fixture is selected based on critical photometrics. Each fixture must be replaced only with an exact equivalent.
Fixtures must be aimed in exactly the correct direction.
The fixture catalog number can be obtained from the fixture or from submittals made on the construction project. These submittals also show how to aim the fixture.Anchor: #i1000518
Responsibility of Cities
High mast lighting assemblies, which by agreement are the maintenance responsibility of a city, should also be inspected and serviced as set forth in this section. This work may be performed by the city or its agent. When this inspection and servicing is performed by the city or its agent, districts should occasionally check that the work is performed correctly.
Districts should provide a copy of the shop drawings (pole and high mast ring), submittals, and “as built” plans to cities that are maintaining high mast lighting.Anchor: #i1000533
Further assistance with high mast lighting inspection and servicing may be obtained from TRF.
Construction and maintenance videos are available through TRF.
