Section 4: High Mast Lighting Inspection and Servicing
Introduction
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.
Districts
should lower the ring, inspect and maintain the high mast pole assembly,
and clean the luminaires on a regular interval such as every three
to five years, in addition to repairing as needed.
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
) or a similar form. Districts must retain these completed
inspection forms
for the duration of the District’s inspection
interval.
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
in
the form of a check list.
Replacing Fixtures
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 and oriented 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.
Responsibility of Cities
High mast lighting assemblies under 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 submittals, and “as
built” plans to cities that are maintaining high mast lighting.
Assistance
Further assistance with high mast lighting inspection and
servicing may be obtained from TRF.
Construction and maintenance videos are available through
TRF.
